SCIENCE OF THE MONTH: NOVEMBER 2011



Danica Mae Camacho, Philippine's symbolic 7 billionth baby  

1 November 2011:  India's most populous state Uttar Pradesh greeted the arrival of the world's seven billionth baby, yesterday morning . The symbolic seven billionth baby is a girl child named Nargis, born to Ajay and Veenita Yadav of Dhanaur village in Mall block on the outskirts of Lucknow, the capital of Uttar Pradesh. Celebrations were also being held in the Philippines, where Danica May Camacho was named the seven billionth baby.In Bangladesh, authorities named another baby girl Oishee as the world's seven billionth child. With countries across the world, including Combodia, staking claim to being home to the seven billionth baby, UN Chief Ban Ki Moon said his office would not be able to pin-point who the world's seven billionth inhabitant is and where the baby was born.

2 November 2011: The Forest Department of Kerala has just completed the first-ever ornithological survey for the Malabar region recording 341 species of birds.The survey spaned locations in North Kerala, which covers Palakkad, Malappuram, Kozhikode, Wayanad, Kannur and Kasargode districts.Yellow-browed Bulbul (iole indica) is credited with the highest density (122.4 birds/sq km).22 of the 341 species surveyed belong to globally-threatened category as notified by IUCN. Alarmingly, of the 22 threatened species 17 are residents and, of which 9 are specifically endemic to Western Ghat. The survey was conducted by an efficient team of five ornithologists led by Shri.C.Sasikumar. Link: http://www.keralaforest.org

3 November 2011: A group of thirty-one Indian scientists from Indian Council of Agricultural Research (ICAR) Institutes, State Agricultural Universities and Banaras Hindu University, have achieved a break through in decoding the genome of Pigeonpea (Cajanus cajan), the second most important pulse crop of India. The pulses variety also known as 'Arhar' and 'Tur'is an important grain legume crop of India. About 85% of the world Pigeonpea is produced and consumed in India where it is a key crop for food and nutritional security of the people. India imports Pigeonpea from Myanmar which is the second largest producer.This is the first plant genome sequenced entirely through a network of Indian institutions. Link: http://www.nrcpb.org

4 November 2011: The genome of Wheat- the most important crop globally - will be cracked within the next three years. Indian scientists have joined 16 other nations - the US, the UK, France, Italy, Switzerland, Germany, Czech Republic, Norway, Israel, Turkey, Russia, China, Japan, Australia and Argentina - in the initiative.The department of biotechnology (DBT) has sanctioned about Rs 34 crore for over four years to three institutes - Punjab Agriculture University, ICAR and Delhi University, for the project which is likely to be completed in five years. Wheat has 21 chromosomes and each will be decoded by the 21 Indian scientists. Once wheat's genetic code is cracked, it will help in developing disease-resistant wheat faster.

5 November 2011: Indian scientists are working on a device to detect tuberculosis (TB) in the early stage of the disease by trapping human breath in air-tight plastic jars. An electric nose that would sniff out sick molecules in a person’s breath is being developed by a four-member research team at the Delhi-based International Centre for Genetic Engineering and Biotechnology (ICGEB) to produce a faster diagnosis of the deadly but curable disease.Late detection of this infectious illness means most patients are treated at advanced stage. Available tests take days, sometimes weeks, to show results. Early diagnosis and timely treatment could potentially save lives, reduce medical costs and prevent the spread of infection.

6 November 2011Revolutionizing cancer treatment throughout the world and serving as an excellent example of highly effective patient-oriented research, the Eldorado Cobalt-60 radiation technology, nicknamed the "Cobalt Bomb", was first installed at London Health Science Centre on October 23, 1951. This was world's first cancer treatment with Cobalt-60 radiation took place at Victoria Hospital. This marked an important milestone for both the fight against cancer and LHSC's emergence as a leader in the field of radiotherapy.Cancer treatment technologies have steadily progressed since the introduction of the mega-voltage period in 1951. Today, linear accelerators with more penetrating x-rays and built-in 3D imaging capabilities are used in most developed countries. Link: http://www.lhsc.on.ca


7 November 2011: Almost twenty-eight years after it set up the first permanent research station in the South Polar region, India is all set to commission and occupy third such station, named as 'Bharti', in Antarctica by March next year. After 'Bharti' becomes operational, India will join the league of select nations that have multiple operation stations in the region. The new station is located almost 3,000 km away from the existing 'Maitri' station which has been serving the nation since its inception in 1988-89. India’s first station in Antarctica was Dakshin Gangotri (1983. After decommissioning, it had been marked as a historic site.Link: http://www.ncaor.gov.in

8 November 2011:An 400m-wide (1,300ft) asteroid will pass by the Earth today, closer to it even than the Moon. It poses no danger to the Earth and it will be invisible to the naked eye. Asteroid 2005 YU55's closest approach, at a distance of 325,000km, will be at 2328GMT. It is the closest the asteroid has been in 200 years. It is also the largest space rock fly-by the Earth has seen since 1976; the next visit by such a large asteroid will be in 2028. Two radio telescopes - the Goldstone Observatory in California, US and the Arecibo Observatory in Puerto Rico, US - will be tracking radio echoes off it in a bid to understand better what it is made of and how it is shaped.Link: http://www.gdscc.nasa.gov

9 November 2011: A recent butterfly survey in the North Wayanad Forest Division organised jointly by the Ferns Naturalists Society, an environment organisation, and the Forest and Wildlife Department reported the sighting of 140 species, including 17 which had not been hitherto reported in the region.Rare species such as Yellow-Jack Sailer and Club Beak were sighted at the Thirunelly reserve forest. Species such as Orange Awlet, Nilgiri Tiger, Tamil Lacewing, and Malabar Banded Swallow-tail were sighted in the Periya reserve forest, Brahmagiri Hills, Hilldale reserve forest, and at the Kunjome forest.The new species in the region included Black-Veign Sergeant, Dark Pierrot, Nilgiri Tiger, Blue Pansy, Common Banded Demon, and Yellow-Jack Sailer.

10 November 2011: India-born scientist Har Gobind Khorana, who won the 1968 Nobel Prize in Physiology or Medicine, died in United States. He was 89. Khorana was born in 1922 in Raipur village of that part of Punjab which is now part of Pakistan. He was Massachusetts Institute of echnology(MIT)’s Alfred P. Sloan Professor of Biology and Chemistry emeritus. In 1976, Khorana achieved the synthesis of the first fully functional manmade gene in a living cell. He was among the pioneers of the now-familiar series of three-nucleotide Codons that signal to the cell which amino acids to use in building proteins, for example, Uracil-Cytosine-Uracil, or UCU, codes for the amino acid Serine, while CUC codes for Leucine.

11 November 2011: Russia has launched an audacious bid to scoop up rock and dust samples from the Martian moon Phobos and bring them back to Earth for study.The dusty debris should provide fresh insights into the origin of the 27km-wide moon that many scientists suspect may actually be a captured asteroid.The mission is called Phobos-Grunt - "grunt" means "soil" in Russian.The venture is also significant because it is carrying China's first Mars satellite-Yinghuo-1. But as per the latest report, the probe is stuck in its earth orbit as its engines failed to fire.After the booster rocket put the spacecraft on a support orbit around the earth the probe’s own engines were to start to put it on a trajectory to Mars, but they did not.

13 November 2011: Scientists claim to have discovered two huge sunken islands in the Indian Ocean, which once formed part of the last link between India and Australia. A team from Sydney University, Macquarie University and the University of Tasmania say the two islands, about the size of Tasmania, were once part of the supercontinent Gondwana and are more than 1.5 kilometres underwater. The discovery was made while the scientists were mapping the seafloor of the Perth Abyssal Plain.The islands, called "micro continents", were formed when India began to move away from Australia, 130 million years ago during the Cretaceous period, when dinosaurs roamed the Earth.

14 November 2011: Scientists from Centre for Cellular and Molecular Biology (CCMB), Hyderabad have named their newly discovered bacteria as an honour to India and Indian scientists. Bacillus isronensis was named in honour of ISRO while another microbe from a Himalayan glacier was named after CCMB (Bacillus cecembensis).Another microbe from Antarctica was christened as Arthrobacter gangotriensis in memory of Dakshin Gangotri, the first Indian research station set up in Antarctica. One of the microbes found in Indian Ocean was named in honour of the founder-director of CCMB, P.M. Bhargava (Bhargavaea cecembensis).The other names are Indibacter alkaliphilus, Pedobacter himalayensis, Bacillus aryabhattai, Sphingobacterium antarcticus.Link: http://www.ccmb.res.in

15 November 2011: The Jim Corbett National Park here on Tuesday opened its gates to wildlife enthusiasts for a landmark season, having turned 75. The park will now remain open to visitors till June 15 next year.While Corbett has succeeded in recent times in making the surrounding community active stakeholders in its activities, there was a need to frame central-level policies on tourism to solve problems related to sustainable tourism that is currently faced by parks all over India, including Corbett. To mark the platinum jubilee, there is a newly introduced online reservation system for visitors.Visitors looking to book passes for entry to the park can now log in to corbettonline.uk.gov.in to make their reservations.

16 November 2011: A team of scientists at the Indian Institute of Petroleum (IIP) here has developed a new technology to convert environmentally-hazardous plastic into petroleum products. After nearly a decade-long experiments, the team of six scientists of IIP led by its Director Madhukar Omkarnath Garg has managed to achieve a breakthrough in developing a "combination of catalysts" which can convert the plastic either into gasoline or diesel or aromatics along with LPG as a common byproduct. Moreover, the process is completely environmental friendly as no toxic substances are emitted. The unique features of the technology is that liquid fuel- gasoline and diesel, meets Euro III fuel specifications and different products can be obtained from the same raw material simply by changing the catalysts and operating parameters.

17 November 2011: GP Birla Observatory and Astronomical Research Centre, one of the amateur observatories in the country will be opened in Hyderabad today. The G P Birla Observatory and Astronomical Centre is situated within the sprawling B M Birla Science Centre, which is a tribute to one of the greatest visionaries and philanthropists of India, Padma Bhushan Late Mr. Ganga Prasad Birla. The roof of the building the Astronomical Observatory houses the powerful C-11 Telescope which is an ultra modern compact telescope instrument capable of detecting even Exoplanets. This has been set-up in collaboration with Uranoscope De France. The Observatory is an Indo-French collaborative effort and is one of the few public observatories in India.

18 November 2011: According to scientists from the University of Texas at Austin –a pleasant city by the way– as well as other contributing scientists, they’ve discovered what they believe to be a large body of liquid water on Jupiter’s moon Europa. The body of water is so large, they compare it to the North American Great Lakes. The water could represent a potential habitat for life, and many more such lakes might exist throughout the shallow regions of Europa’s shell, lead author Britney Schmidt, a postdoctoral fellow at The University of Texas at Austin’s Institute for Geophysics, writes in the journal Nature.Based on similar processes seen here on Earth, the researchers developed a four-step model to explain how the features form on Europa.

19 November 2011: India’s longest distance travelling train, Dibrugarh-Kanniyakumari Vivek Express was flagged off at Dibrugarh Railway Station, Assam today. The weekly train (15905/15906) will travel a distance of 4,286 kilometres from Dibrugarh railway station to Kanniyakumari through the states of West Bengal, Orissa, Andhra Pradesh, Tamil Nadu and Kerala. The train will reach its destination in about 82:30 hours.The train has been christened as Vivek Express in the name of the great saint Swami Vivekananda. Earlier, the longest distance travelling train was the Himsagar Express, which travels from Jammu Tawi to Kanniyakumari, covering a total distance of 3715 kilometres in about 71 hours.

20 November 2011: Two species of frogs found in Kerala are endangered, a study has found. The Green-eyed Bush Frog and the Resplendent Shrub Frog, found in the Western Ghats and in Munnar, have been listed as ‘critically endangered’ species in the paper published in the November issue of the IUCN magazine.The Bush frog, whose scientific name is Raorchestes chlorosomma, is found in the hilly areas of Munnar. Another is the "Shrub frog" found only in certain parts of Anamudi. Its scientific name is Raorchestes resplendens. The "Shrub frog" was found in 3 sqkm of the Eravikulam National Park in Munnar. Redline Torpedo Barb (Puntius denisnii-colloquially named "Miss Kerala", an ornamental fish found in the Western Ghats and in certain parts of South India, was also termed critically endangered.

21 November 2011: A group of international scientists from India, Tanzania and Thailand are doing a research to find out ideal variety of 'Bitter gourd’ that could beat diabetes.Today, India has the highest rate of diabetes in the world. The city of Hyderabad as been selected for ‘Project bitter Gourd’ as it has emerged as the diabetes capital of the country. As many as 10 hybrids of the Indian bitter gourd are being studied for their germplasm and chemical constituents, particularly Momordicin. The higher the content of Momordicin, the higher is the anti-diabetes effect.Along with the Indian hybrids, 10 hybrids from Thailand are also included in 'Project Bitter Gourd' that is sponsored by the Asian Vegetable Research and Development Centre.

22 November 2011Assam has declared tea as the ‘state drink’ in a bid to encourage the industry. Going one step forward, former president APJ Abdul Kalam described tea as India’s ‘national drink’ saying over 22% of tea produced worldwide is consumed in India. The declaration came at inaugural function of the three-day World Tea Science Congress. Indian Tea Board's main focus in the 12th Plan was to brand Indian tea under one umbrella and one logo. As the country was losing out major markets due to inadequate promotions, she said, an aggressive programme called "555" would be introduced five focus countries for five years and for five identified activities. The five countries are Russia, Kazakhstan, USA, Iraq and Egypt which are the biggest buyers of Indian tea. Link: http://www.tocklai.net/teacongress

23 November 2011: Four of the seven countries bordering the Himalayas, India, Bangladesh, Nepal and Bhutan have agreed to work together to deal with the harmful effects that climate change is expected to bring to the region. They were meeting at the Climate Summit for a Living Himalayas in Thimphu, Bhutan, last weekend. There, they agreed to work together on issues including food and water security. All four countries rely on melt water from Himalayan glaciers. Historically, Himalayan countries have rarely worked together, but to have a lasting impact, though, the group will need to include China, Pakistan and Afghanistan.

24 November 2011: The first night-flowering orchid known to science has been discovered by botanists on the island of New Britain, near Papua New Guinea. The new species, called Bulbophyllum nocturnum, is the first which has flowers which consistently open up at night and close in the morning, say botanists. It was found by Dutch orchid specialist Ed de Vogel. According to de Vogel, the buds would flower at 10pm before closing again around twelve hours later. The flowers only last one night. Botanists aren't sure why this species flowers after dark but suggest it might be because its pollinators are midges which forage at night.The newly-described orchid belongs to a group of species called Epicrianthes.

25 November 2011: Researchers at the University of Massachusetts Medical School have released the full genomic sequence of Monarch butterfly. This adds a new fame to this iconic butterfly, which is famous for its ability to travel up to 2,000 miles from North America to central Mexico every fall.  The new genome is the first for any butterfly. It is also the first complete genome of any long-distance migrant.The researchers focused their genome analysis on pathways known to be critical for this migration, including those responsible for vision, the circadian clock, and oriented flight.The genome also revealed the complete set of genes required for synthesizing juvenile hormone.The findings appeared in November 23rd issue of the Cell.Link:http://www.sciencedirect.com

27 November 2011: The world's biggest extraterrestrial explorer, NASA's Curiosity rover, rocketed toward Mars on Saturday on a search for evidence that the red planet might once have been home to itsy-bitsy life. It will take 8 1/2 months for Curiosity to reach Mars following a journey of 354 million miles.An unmanned Atlas V rocket hoisted the rover, officially known as Mars Science Laboratory, into a cloudy late morning sky. A Mars frenzy gripped the launch site, with more than 13,000 guests jamming the space center for NASA's first launch to Earth's next-door neighbor in four years, and the first send-off of a Martian rover in eight years. It is the first astrobiology mission to Mars since the 1970s-era Viking probes.

28 November 2011: Representatives from 194 countries and thousands NGOs are gathering today in Durban, South Africa, to participate in a new round of climate negotiations, including how to extend the Kyoto Protocol. The Durban Conference, the COP 17, will hold from November 28 to December 9, aiming to make efforts to reduce greenhouse gases emissions under the United Nations Framework Convention on Climate Change (UNFCCC).Efforts to negotiate a successor to the Kyoto Protocol, which committed industrialized nations to reducing greenhouse gas emissions by a set amount by 2012, have been on hold since the failure of the climate conference in Copenhagen.The conference will also consider ways to raise $100 billion a year for the Green Climate Fund to cope up with global warming.Link: http://www.cop17-cmp7durban.com


29 November 2011: The International Cooperation to Sequence the Atlantic Salmon Genome (ICSASG, the "Cooperation") has awarded the Phase II contract for next-generation sequencing and analysis of the Atlantic salmon genome to the J. Craig Venter Institute (JCVI) in Rockville, Maryland. JCVI will be sequencing the Salmon genome using next-generation technologies, including assembly to integrate Sanger and next-generation sequence, and comparative genomics. This effort is expected to generate a high-quality resource for those responsible for the management of wild salmon stocks and the salmon aquaculture industry, as well as providing a reference genome for work with other Salmonids. The salmon genome is large and contains repetitive sequences which make it a more difficult sequencing effort. Link: http://web.uvic.ca/grasp/

MOVIE OF THE MONTH: NOVEMBER 2011

            
Director        :Andrew Niccol
Writer          : Andrew Niccol
Camera        : Roger Deakins
Distributor    : 20th Century Fox
Runnng Time: 115 minutes

There are only a handful of science fiction movies that deserve or achieve the level of being called a cult classic. Such futuristic “controlled society” programs as Logan’s Run, Escape From New York and The Island came to mind quickly when the trailers were released for Justin Timberlake’s new sci-fi adventure In Time. It’s easy to compare the story ideas of a world where people stop aging at 25 and are running on a society where an implanted life clock replaces currency.

Previously titled Now and I'm.mortal, In time has a story set in a retro-future when the aging gene has been switched off. At the age of 25, aging stops, meaning that everyone looks 25 forever and could be immortal. But to prevent overpopulation, each person is genetically engineered so that by default they have just one more year to live after 25. Embedded in their arm is a bioluminescent clock displaying how much time they have left. Once the clock reaches zero, they die.  

But this does not mean that everyone automatically dies at 26. Time can be transferred into and out of persons, and therefore, it has become the new currency. People earn time by working and spend it to pay for everyday necessities. For example, in the film, a coffee costs four minutes and a day's labor in a factory will earn a worker a little over 24 hours. Time can also be stolen or robbed from another person. Consequently, the poor are constantly trying to earn, steal, beg, or borrow enough time to stay alive for one more day, while the rich can theoretically live forever (unless they are murdered or killed in accidents).     

Different economic classes are segregated into different "time zones." To preserve the status quo, it costs a whole year just to cross the border into a wealthy time zone.A wealthy man named Henry Hamilton (Matt Bomer) goes to a bar in the impoverished time zone of Dayton, having over a hundred years left on his clock. He attracts some unwanted attention from a gang of robbers who try to steal his time, but is saved by local poor man Will Salas. After they find shelter in an abandoned warehouse, Hamilton explains to Salas that he is 105 years old and tired of life.

Later, while Salas is asleep, Hamilton transfers his time to Salas.  Waking up, Salas discovers he now has over 116 years on his clock. Out the window, he sees Hamilton sitting on the edge of a bridge as his time runs out. Before Salas can do anything, Hamilton dies and falls into the shallow water of a storm drain.Salas uses Hamilton's time to access the wealthy time zone of New Greenwich, but then finds himself accused of Hamilton's murder.  

He is forced to go on the run from an FBI-like police force known as the "Timekeepers" led by Raymond Leon, as well as from a hoodlum-like middle-aged mob called the "Minutemen", led by a senior citizen named Fortis, who is 75 years old. Along the way, Salas become acquainted with Sylvia Weis , and her father, timelending magnate Phillippe Weis.

BOOK OF THE MONTH: NOVEMBER 2011


Title:         Blogging as Change: 
                 Transforming Science 
                 and Math Education 
                 through 
                 New Media Literacies 
Authors  : Raffaella Borasi, April Luehmann 
Publisher: Peter Lang Publishing
Pages      : 368 
ISBN       : 13: 978-1433105586
Price        : $149.95


Blogs and other Web 2.0 technologies are rarely being used in schools in the powerful ways they are taken up outside of school—in ways that position learners as producers of their own knowledge. These radically different engagements in new media literacies are even more rare in science and math classrooms, but a research team from the University of Rochester's Warner School of Education has recently released a book to help practitioners and researchers discover the true power of blogging in science and math education.

April Luehmann, associate professor, and Raffaella Borasi, Frederica Warner Professor of Education, the co-editors of Blogging as Change: Transforming Science and Math Education Through New Media Literacies believe that blogging can support classrooms in realizing reform-based science and math education.Blogging can promote authentic engagement in learning and teaching and contribute to a much-needed transformation of science and math education so that all students, especially those historically marginalized from participating in their school-based education, are involved in doing the real work of science and mathematics.

The book was inspired from Luehmann's own practice as a teacher educator as well as years of studies on part of her research team on the use of blogs in a number of different instructional contexts. The 14 chapters in Blogging as Change, which were written collaboratively by Luehmann and her graduate students as well as Borasi, illustrate and critically analyze the potential of blogging to encourage different ways of communicating, interacting, learning, and thinking about science and math.

Grounded on empirical data gathered from teachers and students engaged in blogging in a variety of contexts, the book examines ways in which blogging can be most conducive to transforming science and math classrooms into places that are more equitable and just—places that invite and nurture new, more social and authentic, forms of participation and learning for both students and teachers.

The book focuses on two different, yet valuable, forms of blogging. The first is classroom blogging, where blogging practices are introduced and often designed by teachers, and taken up and often customized by students. Classroom blogging can engage students more centrally in their own learning and in ways that transform their identities in science and math. The second is teacher blogging, where teachers develop professional blogs as a tool to support professional learning. The book looks at the power of blogging not only to foster new modes of interactions in the classroom through classroom blogs but also as a tool to support teachers' reflection, introspection, meaning-making, community-building, and growth through new forms of digitally-supported communication.

Luehmann is a science educator, teaching in the science teacher preparation and doctoral programs at the Warner School. She focuses her research on the design and use of new media literacies, out-of-school learning contexts and experiences, and innovative teacher development programs to explicitly address issues of equity and social justice. Borasi is dean of the Warner School and a mathematics educator with a special interest in an inquiry approach to teaching school mathematics, school mathematics reform, and professional development.

EVENT OF THE MONTH: NOVEMBER 2011


The 17th Conference of the Parties (COP17) to the United Nations Framework Convention on Climate Change (UNFCCC) and the 7th Session of the Conference of the Parties serving as the meeting of the parties (CMP7) to the Kyoto Protocol, will be held in the sunny city of Durban, South Africa.

Since the UNFCCC entered into force in 1995, the Conference of the Parties (COP) to the UNFCCC have been meeting annually to assess progress in dealing with climate change.The COP adopts decisions and resolutions, published in reports of the COP.  Successive decisions taken by the COP make up a detailed set of rules for practical and effective implementation of the Convention.

In 1992, the United Nations Framework Convention on Climate Change (UNFCCC) sets an overall framework for intergovernmental efforts to address climate change. It is called a framework convention because it is seen as a starting point of addressing the problem of climate change. The Convention entered into force on 21 March 1994.The ultimate objective of the Convention is “to stabilise greenhouse gas concentrations at a level that will prevent dangerous human interference with the climate system”.

As with previous United Nations (UN) Climate Change conferences, participation at COP 17 and CMP 7 will be restricted to appropriately nominated representatives of Parties, observer States, accredited observer organizations and the accredited media.Those Parties to the Convention that are not Parties to the Protocol may participate as observers in the meeting of the Parties.

Thousands of participants from government representatives to observer organizations take part in sessions.  The COP 15 in Copenhagen in 2009 attracted over 24,000 delegates, including some 10,590 government officials, over 13,000 representatives of UN bodies and agencies, intergovernmental and non-governmental organizations, and 3,221 accredited media members. COP 16 / CMP 6 in Cancun last year had over 11,800 participants.


SPECIES OF THE MONTH: NOVEMBER 2011

                                                                                 
Kingdom: Plantae
Division  : Cycadophyta
Class      : Cycadopsida
Order     : Cycadales
Family    : Cycadaceae
Genus     : Cycas


It was believed that dinosaurs in the Jurassic period roamed among them. But now, a Sydney-based scientist says she has proven that modern cycads or `dinosaur plants' did not grow 200 million years ago.Dr Nathalie Nagalingum, research scientist at Sydney's Royal Botanic Garden said that for her study, she look at the plant's 'molecular clock' - a way to age species based on the rate of change in their DNA.She found that today's living species are different to those found during the Jurassic period, when dinosaurs roamed.

"We then looked at the extinction of dinosaurs 65.5 million years ago and found there was a gap of 55 million years between when dinosaurs were extinct and modern cycads started to diversify," she says. "We can now say that living cycad species are not ancient or leftovers from dinosaur times. They evolved independently of dinosaurs only 10 million years ago."

After studying 11 groups of the plants, Nathalie discovered that all cycads, no matter were they grew, began diversifying 10 million years ago. This indicates a trigger may have been responsible."It seems that the trigger was a change in the climate; that is, when global cooling began and when the world started having distinct seasons."She says climate change is now threatening the species. 

"Today, cycads are listed as [among] the most endangered plants and most likely victims of a mass extinction being caused by humans," she says. "Cycads are very slow-growing plants so it's hard to predict whether cycads can survive, now that climate change is occurring at a much faster rate."Nathalie's findings were the result of her research at Harvard University and the University of California, Berkeley, using a combination of fossils and DNA sequences. The study was published in the journal Science this week.

1 October 2011: The Bangalore-based Ganit Lab sequenced and analyzed the genome and coding parts of the Neem plant. Neem tree and its parts have been used since time immemorial in the country and its insecticidal, pesticidal, fungicidal and medicinal properties are well known. Understanding the molecular architecutre of the Neem genome and its various coding parts will enhance the knowledge about this wonder species further. Ganit labs is currently building an open access portal to host information gathered from the current study on genome, genome architecture, coding parts and molecular evolution of the Neem plant. In addition to Neem, Ganit Labs has sequenced 'tongue cancer genomes' from Indian patients. Karnataka Government's IT and BT department is funding Ganit Labs, a non profit organisation.Link: http://www.ganitlabs.in

2 October 2011: This year's Ig Nobel prizes were annouced last night in a ceremony at Harvard University. The biology prize was given to a team or researchers for discovering that certain types of beetles try to mate with particular types of short, dark beer bottles in Australia which they confuse for female beetles. Japanese researchers who have applied for a patent for an odor-generation alarm based on the pungent sushi condiment wasabi received the chemistry prize. Other winners had research looking at why we sigh, whether yawning is contagious in the Red-Footed Tortoise etc. Presented by the Annals of Improbable Research Magazine the Ig Nobel Prize awards are famous for "first making people laugh, and then make them think”.Link: http://improbable.com

3 October 2011: Three scientists shared this year's Nobel prize for medicine. Bruce Beutler, of the US, Jules Hoffmann from France and Ralph Steinman from Canada all shared the prize. Profs Beutler and Hoffman discovered how the body's first line of defence was activated. In 1996, Prof Hoffmann discovered that a gene called "Toll" was essential for kick starting the innate system in fruit flies. Without the gene, the flies could not "sense" and then fight bacterial infection. An equivalent gene, Toll-like receptor, was found by Prof Beutler in 1998 in his study on mice. Prof Steinman discovered the dendritic cell, which helps defeat infection.He showed that it can act as a bridge between the two immune systems, deciding whether to activate the adaptive system.

4 October 2011: Three U.S.-born scientists won the Nobel Prize in Physics for discovering that the universe is expanding at an accelerating pace, a stunning revelation that suggests the cosmos will eventually freeze to ice. The American scientist Saul Perlmutter would share the award with U.S.-Australian Brian Schmidt and Adam Riess, another American. Working in two separate research teams during the 1990s, the scientists raced to map the universe's expansion by analyzing a particular type of supernovas, or exploding stars. Perlmutter, heads the Supernova Cosmology Project at the Lawrence Berkeley National Laboratory and University of California, Berkeley. Schmidt, is the head of the High-z Supernova Search Team at the Australian National University in Weston Creek, Australia. Riess,is an astronomy professor at Johns Hopkins University and Space Telescope Science Institute in Baltimore, Maryland. Link: http://www.nobelprize.org
5 October 2011: Israeli scientist Daniel Shechtman won this year's Nobel Prize in Chemistry for discovering a material in which atoms were packed together in a well-defined pattern that never repeats. Shechtman, 70, a professor of materials science at Technion - Israel Institute of Technology won "for the discovery of quasicrystals." Dr Shechtman had to fight a fierce battle against established science to convince others of what he had first seen in his lab at the National Institute of Standards and Technology in Washington - formerly called the National Bureau of Standards - on an April morning in 1982. Dr Shechtman himself is said to have cried "Eyn chaya kazo", which translates from the Hebrew as "there can be no such creature". Link: http://www.nobelprize.org

Craig Venter Institute, a nonprofit research facility in Rockville, Va., and two companies, Synthetic Genomics andSynthetic Genomics Vaccines.Link: http://www.jcvi.org/

8 October 2011: ESA’s Venus Express spacecraft orbiting Venus has discovered an ozone layer high in the planet’s atmosphere, similar to that surrounding Earth and Mars according to astronomers. The study was recently presented at the Joint Meeting of the European Planetary Science Congress and the American Astronomical Society’s Division for Planetary Sciences.While observing stars visible right at the edge of the planet, set through its atmosphere, ESA’s Venus Express spacecraft made the discovery. Ozone has also been regarded as a potential biomarker, since it traces the distribution of molecular oxygen. Ozone was found previously only in the atmospheres of Earth and Mars.

10 October 2011: A team of researchers trawling the ocean floor have just published their findings of the world's new largest virus, found lurking off the coast of Las Cruces, Chile. The virus with the scientific name Megavirus chilensis can even be viewed with a basic light microscope. The previous virus record holder was Mimivirus, which boasted the largest diameter of any virus to date. The Megavirus' DNA features 1,259,197 base pairs, which encode some parasitic bacteria-like features. Mimivirus was found in 1992, lurking in an amoeba in Bradford, England. Most viruses fall in the range between 20 and 300 nanometres, making both Mimivirus and the new Megavirus titans of the microscopic world. Link: http://www.giantvirus.org/

13 October 2011: An international team of scientists has sequenced the entire genome of a varient of the Plague bacterium (Yersinia pestis), extracted from skeletons more than 700 years old. It's the first time scientists have been able to draft a reconstructed genome of any pathogen older than 100 years or so, and could lead to a better understanding of modern infectious diseases. The team found that a specific variant of the Yersinia pestis bacterium was responsible for the plague that killed 50 million Europeans between 1347 and 1351.The team analyzed skeletal remains from victims buried in the East Smithfield plague pits in London, located under what is now the Royal Mint.The direct descendants of the Smithfield bubonic plague still exists, however, killing 2,000 people each year.

14 October 2011: The high peaks of the Himalayas may soon be a beacon for adventurous solar power entrepreneurs, suggests a new study.Other regions not traditionally considered hotbeds of solar power potential include the Andes of South America and Antarctica, note Takashi Oozeki and Yutaka Genchi with the National Institute of Industrial Science and Technology in Japan.In addition to copious amounts of sunlight, these regions are chillier than the usual suspects such as the southwestern United States and the deserts of North Africa. Colder temps increase the operational efficiency of certain photovoltaic solar cells, which turn sunlight into electricity.The finding is based on a global analysis of photovoltaic potential that takes into account the effect of ambient temperature, something the team says has not been done before.

15 October 2011: Bristol University students, both past and present, are behind the most popular student-run online news magazine in the country. Erudition began as a print publication but has evolved into a collection of three magazine-style websites, each covering the broad topics of the economy, politics, science, engineering, arts and culture.The latest addition to the online series is Experimentation, which covers the latest news and views on the world of science and engineering. It has just been launched by editor-in-chief Alistair Jacklin, who has worked hard with his news team over the last six months to create the website. The websites, which are updated with new editions each month, actively promote debate through its news and in-depth features. Link: http://www.eruditiononline.co.uk/

16 October 2011: The contest begins for the new name for New Mexico’s world famous radio telescope facilities. This telescope seeks a new name after completing extensive upgrades, which started in 2001.They are looking for a creative name that reflects the VLA’s future role in astronomy, while still honoring its past achievements of success. The National Radio Astronomy Observatory (NRAO) wants to open up the choice to the public’s creativity.The contest is open until 1 December and the winner will be announced at the American Astronomical Society conference in January.The search for a new name comes after the radio telescope underwent an expansion of upgrades. Officials say the VLA’s original, 1970s electronics have been replaced with state-of-the-art equipment. Link:  http://www.nrao.edu/namethearray/

17 October 2011:The Soviet-era work-horse, Soyuz rocket will be launched from Europe's space base in South America.It will be the first time that the legendary rocket, which traces its lineage to Sputnik and Gagarin, has been deployed outside Russia's bases. And its payload will be the first two operational satellites in Galileo, Europe's €5.4bn rival to the US Global Positioning System (GPS). Soyuz is the world's most successful rocket, with a whopping 1 776 launches under its belt if the count includes forerunners dating back to 1957.Until now, Soyuz has been launched from Plesetsk, in northern Russia, or from Baikonur, in Kazakhstan. Under a 2003 deal, Russia agreed to launch it from ESA's base in Kourou, FrenchGuiana.Link: http://www.esa.int

18 October 2011:Researchers have sequenced the genome of a Dutch woman who held the title of the world's oldest person when she died, aged 115. The study of Hendrikje van Andel-Schipper, could help to understand the biology of ageing, scientists say. A team led by Henne Holstege, of the VU University Medical Center in Amsterdam, has begun to compare DNA from van Andel-Schipper's blood and brain, to determine how different genetic mutations arise in these tissues. The genome will provide researchers with an unprecedented resource for investigating how DNA contributes to longevity and diseases of old age such as Alzheimer's. Van Andel-Schipper died of gastric cancer, having survived breast cancer at the age of 100.Link: http://www.vumc.com/

19 October 2011: The documentary produced by Indian Institute of Science Education and Research (IISER), Chandra: In Quest of Perspectives, on the life and works of the astrophysicist Subramanyam Chandrasekhar will be aired on Doordarshan today at 9.30am.His work showed that a star higher than the so called "Chandrasekhar Limit"(mass 1.44 times that of the sun) will continue to collapse beyond what is called the White Dwarf to become a Neutron star or a Black hole following a supernova explosion. The documentary, an initiative to popularise science, is part of the centenary celebrations highlighting Prof S. Chandrasekhar’s contribution to physics and mathematics in general and astrophysics in particular. Link: http://www.iiserpune.ac.in/

20 October 2011: Stem cell scientist Hwang Woo-suk at the Sooam Biotech Research Foundation released eight Coyotes also known as the American jackal or the Prairie Wolf (Canis latrans) that he and his research team claimed to have cloned in Pyeongtaek, Gyeonggi Province. The coyotes will be donated to a wildlife center. With this Hwang has become the world`s first to clone coyotes. Amother news said that Royal Blue Boon, the Quarter Horse mare which was the first commercially cloned horse, died last week in Texas, at the age of 31.The Quarter Horse mare was one of the leading producers of cutting horses in recent years. The clone--the filly Royal Blueboon Too-still resides on Hall's farm.

21 October 2011: 2011 New data released by NASA and NOAA show in September the Ozone hole over Antarctica was the 9th largest on record – stretching over 16.17 million square kilometers. On the southern hemisphere the story seems much the same. Earlier this month over Antarctica the 10th lowest ozone concentration was measured: 102 Dobson units. CFC-induced ozone breakdown requires: extremely low stratospheric temperatures and sunlight. That’s why the ozone layer depletes more just after winter, when temperatures 10 kilometers up in the sky can be low enough for polar stratospheric ice clouds to form, and the onset of spring adds a little UV radiation to get the catalytic breakdown reaction going.Link: http://www.wmo.int

22 October 2011: Fresh from the successful launch of Megha Tropiques satellite on October 12,India and France today eyed another milestone of a new satellite dedicated to environment monitoring. The forthcoming launch of SARAL, a joint satellite to study sea surface altitude would be another milestone in space cooperation. SARAL would help ocean scientists gather accurate data on the rise in the sea level which could threaten the low lying and coastal areas of the country. The joint statement by Indian Space Research Organisation (ISRO) and the French National Space Agency (CNES) will be pursuing the cooperation further within the framework of a memorandum of understanding signed in December last year.

23 October 2011:The 21-year-old German Roentgen Satellite, or ROSAT, re-entered Earth’s atmosphere over the Bay of Bengal today. It is not known whether any debris reached Earth’s surface.Damage to property caused by ROSAT has not been reported. Engineers expected that 1.7 tons of debris from the X-ray astronomy satellite would survive re-entry and reach the surface, creating a 1-in-2,000 chance that someone would be injured by it.NASA’s Upper Atmosphere Research Satellite, or UARS, re-entered the atmosphere on Sept. 24 and plunged into the Pacific Ocean, well away from the North American coastline. The 6.5-ton UARS spacecraft was the largest NASA satellite to fall uncontrolled from orbit since 1979.  

24 October 2011: China would next month launch its much-awaited Mars probe mission, entering further deep into space exploration following two lunar projects, as the country braces itself for a deep space competition with the US. China's first Mars probe will be launched between November 8 and 20, after two years delay, a top scientist said. Yinghuo-1, a micro-satellite weighing 110 kg, will be sent into space with Russia's Phobos-Grunt mission at the Baikonur Cosmodrome launch site in Kazakhstan. The probe is expected to enter a preset orbit around Mars between Aug-Sept next year. Last month China successfully launched its maiden space lab Tiangong-1.Link: http://www.cnsa.gov.cn

25 October 2011: In context of World Polio Day today, Government of India declared that only one polio case has been detected so far this year in the country making it the longest polio-free period ever since eradication efforts were launched. The only case of polio reported this year has been from Howrah district in West Bengal on 13th January 2011 as compared to 39 cases in the country in the same period of 2010. For the first time no case of polio has been reported from UP (since April 2010) and also from Bihar (since September 2010). No case of type 3 polio has come up for over a year.  Closest ever to eradicating polio, Government of India has decided to treat any fresh case of polio as a 'public health emergency'.

26 October 2011: Now an international team of scientists led by Dr Aaron Jex from The University of Melbourne have sequenced the genome of the common roundworm (Ascaris suum). The team hope the genetic roadmap of the giant worm, which infects pigs, can lead to the development of treatments for both animals and humans. It is a very close relative and excellent model for a really important parasite in humans which is Ascaris lumbricoides. While Ascaris suum causes major losses in the pig industry, Ascaris lumbricoides causes a disease called ascariasis, which kills around 135,000 people — mainly children — each year in developing regions of South East Asia, China, South America and Africa.Their results appear in today's issue of Nature.Link: http://www.nature.com
 
27 October 2011: Bangladesh, India and the Democratic Republic of Congo (DRC) are among 30 countries with "extreme" exposure to climate shift, according to a ranking of 193 nations by Maplecroft, a British firm specialising in risk analysis. Five Southeast Asian nations - Indonesia , Myanmar, Vietnam, the Philippines and Cambodia - are also in the highest category , partly because of the rising seas and increasing severe tropical storms. Maplecroft's tool, the Climate Change Vulnerability Index ( CCVI), looks at exposure to extreme weather events such as drought, cyclones, wildfires and storm surges, which translate into water stress, loss of crops and land lost to the sea. Of 30 nations identified in the new report as at "extreme" risk from climate change, two-thirds are in Africa and all are developing countries. Link: http://maplecroft.com/
 
28 October 2011:A team of researchers including from the Zoological Survey of India, Western Ghat Regional Centre, Kozhikode has discovered a new species of limbless amphibian from Western Ghats. The new species, Ichthyophis davidi, a yellow striped caecilian was discovered from the Belgaum district of Karnataka, which is part of the Western Ghat. Ichthyophis davidi is one of the largest known yellow striped caecilians from Western Ghats and is named in honour of David Gower, Department of Zoology, The Natural History Museum, London, in recognition of his contributions to Indian caecilian studies. The members of the genus Ichthyophis include both striped and non-striped caecilians.The discovery has been published in the latest issue of Current Science. Link: http://cs-test.ias.ac.in

29 October 2011:Indian scientists have mapped the genome of a Sri Lankan individual. The project involved the Centre for Genomic Application, a public-private company floated by the Council of Scientific and Industrial Research (CSIR) and Kolkata-based Institute of Molecular Medicine.Sridhar Sivasubbu, a CSIR researcher involved with the Sri Lankan genome-mapping exercise, said that though the mapping project was a commercial deal, it involved Indian scientists “sharing knowledge” with Sri Lankan collaborators. India was now a $25 million market for genome sequencing applications.Though the Sri Lankan genome was mapped in December, it is yet to be formally announced via a scientific publication.

30 October 2011: On November 8, an asteroid 400 meters across will pass by us, missing the Earth by the very comfortable margin of about 320,000 kilometers. Named 2005 YU55,it is one among those called Potentially Hazardous Asteroid because its orbit intersects that of Earth. But observations have shown that it won’t be a danger to Earth for at least a century, and probably much more, eventhough astronomers world over will be observing it carefully, as it is a very closer pass by. There are plans to use NASA’s Deep Space Network of radio telescopes, as well as the Arecibo ‘scope in Puerto Rico (which was used to make the image above back in April 2010) for observing it.

31 October 2011: In the wake of September’s surprising experimental results that suggested the observation of faster-than-light neutrinos, CERN has announced that it has been re-running the experiment over recent days. Criticisms of the experiment have proposed errors in the time measurement, or have asked whether CERN properly accounted for Earth’s rotation, or queried the statistical analysis of the results. The old experimental design, which used 10 microsecond bursts of protons at CERN to generate the neutrinos, is being replaced by a new design in which the proton bursts will last just a couple of nanoseconds, with a 500 ns gap between bursts.This should permit a more precise calculation, scientists think.
