1 July 2013: Giving a big boost to vanishing tigers, the Maharashtra government approved the Koka Wildlife Sanctuary, 20km from Bhandara. The 92.34 sq km protected area is hardly 10km from New Nagzira and Nagzira wildlife sanctuaries and will act as a gene pool for tigers and wildlife. The proposed sanctuary includes 29 compartments with a total sanctuary area comes to 92.34 sq km. Koka has huge potential for sustaining flagship species such as tigers and panthers. The sanctuary will be an extension of already existing New Nagzira and Nagzira wildlife sanctuaries. In future, the area will be treated as buffer zone of proposed Nagzira-Navegoan Tiger Reserve.

2 July 2013: Today's midnight launch of IRNSS-1 A (Indian Regional Navigational
Satellite System),will enable India to have its own navigational satellite and
its own GPS technology. The satellite is one of the seven satellites
constituting the IRNSS network which will also provide better disaster
management. It was launched from Sriharikota by Polar Satellite Launch
Vehicle-XL (PSLV-XL) which is a four-stage rocket powered by solid fuel
(Hydroxyl-terminated-poly-butadiene) and liquid propellants (unsymmetrical
Dimethyl-hydrazine-hydrate and 25 percent of Nitrogen tetroxide for second
stage and Mono-methyl-hydrazine and mixed Oxide Nitrogen for fourth stage.

3 July 2013: Researchers at
the Institute de Biologia Evolutiva in Spain have made the most comprehensive
catalogue of great-ape genome diversity ever, offering insight into the primate
evolution. The catalogue shows chimpanzees are much more genetically complex
than humans. Researchers sequenced a total of 79 great apes, including
Chimpanzees, Bonobos, Gorillas and Orangutans, as well as seven apes.
Chimpanzees and Bonobos remain humans' closest living relatives, splitting off
from humanity about 5 million years ago. The findings also settle a hot debate
over the relationships among the four chimpanzee subspecies. The new findings
don't change man's position in the evolutionary history of mankind involving
primates. Link: http://www.ibe.upf-csic.es
4 July 2013: Researchers from the University of
Leeds, UK, have found that in the last decade, the Earth's spin has missed a
beat, three times. These seemingly random blips cause days to temporarily
stretch and shrink. Richard Holme of the University of Liverpool, UK, looked at
50 years of GPS and astronomical data to find out that in recent years our
planet's spin has stuttered three times,in 2003, 2004, and 2007. The jumps
interrupt the longer-term changes by a fraction of a millisecond, and last
several months before going back to normal. The researchers from the University
of Leeds says that we need to rethink the dynamics of the Earth's core in the
light of these new findings regarding Earth's spin.This article

5 July 2013: Green Chemistry was this year's theme at the 63rd Lindau
Nobel Laureate Meeting which was concluded in Lake Constance, the picturesque
town on Germany. Under graduate and post graduate students - from 80 countries
participated with 35 scientists, all Nobel Prize winners. Lake Constance hosted
22 students from India, sponsored by the Department of Science and Technology
and the DFG (German Research Foundation). Lindau meet addressed and discussed
renewable energy sources - solar cells, photosynthesis, photobiological
hydrogen production and catalytic production of renewable fuels. And other
topics like Climate change. Link: http://www.lindau-nobel.org
6 July 2013: 'Team Rat', a 25-member
international team of scientists have braved harsh Antarctic conditions of
South Georgia to get rid off rats that were wiping out rare bird populations.
South Georgia is one of the world's last great wilderness areas and amongst the
wildlife on the island are 90% of the world's Antarctic fur seals and half the
world's elephant seals. Four species of penguins nest on the island, including
King Penguins with around 400,000 breeding pairs. The team led by professor
Tony Martin, made 1,000 flights over the Antarctic island to bait 70% of the
island's rat-infested areas, five times larger than any other rodent
eradication project ever undertaken. Link: http://www.sght.org
7 July 2013: Today marked the 10th
anniversary of the launch of NASA’s Mars rover, Opportunity, which was launched
on July 7, 2003. Opportunity landed on Mars' Meridiani Planum on January 25,
2004, three weeks after its twin Spirit (MER-A), also part of NASA's Mars
Exploration Rover Mission, touched down on the other side of the planet. While
Spirit became immobile in 2009 and ceased communications in 2010, Opportunity
remains active as of 2013, having already exceeded its planned activity by 9
years, 95 days (in Earth time). Mission highlights included finding
extramartian meteorites such as Meridiani Planum, and over two years studying
Victoria crater. It reached Endeavour crater in 2011.Link: http://science.nasa.gov
8 July 2013: Yahoo which now owns AltaVista, the
first searchable, full-text database of a large part of the World Wide Web,
decided to close it, today. AltaVista was founded in 1995 by Digital Equipment
Corporation.It was once one of the most popular search engines, but it lost
ground with the rise of Google and was purchased in 2003 by Yahoo!, which
retained the brand but based all AltaVista searches on its own search engine.
AltaVista was publicly launched on December 15, 1995. It was based on the
original idea of Paul Flaherty, a researcher at Digital Equipment Corporation.
The name AltaVista was chosen in relation to the surroundings of their company
at Palo Alto. Link: http://www.altavista.com
9 July 2013: A baby boy has been born to a couple in
the USA through a revolutionary IVF technique, that enables doctors to detect
chromosome defects, even at womb. The technique, developed by British
scientists from the National Institute for Health Research (NIHR) Oxford
Biomedical Research Centre will tremendously help in improving the success rate
of IVF cycles. Until recently, such abnormalities have been hard to detect as
they do not affect the appearance of embryos under the microscope. The new
approach can identify embryos with the correct number of chromosomes and may
cut the cost of embryo screening. It also improves IVF success rates by
around 30%. Link: http://oxfordbrc.nihr.ac.uk
10 July 2013: Death Valley's record temperature of
134 degrees Fahrenheit (56.7 degrees Celsius), the hottest ever measured on
Earth, was set exactly 100 years ago today. For decades, scientists debated
whether El Azizia, Libya, or the Death Valley in eastern California desert had
the definitive claim to the hottest place on Earth. An international
meteorology committee was tasked with investigating the competing claims, but
their efforts were disrupted by a revolution in Libya. In 2011, the Libyan
scientist, Kahlid Ibrahim El Fadli's measurement declared Death Valley as the
hottest-known place on Earth, with the record-setting temperature, marked on
July 10, 1913. Link: http://www.pbs.org
11 July 2013: French researchers have made a new type
of atomic clock that can measure time more accurately. The new device called
Optical Lattice Clock, would only lose just one second in every 300 million
years.Currently, atomic clocks are used to count the seconds, but the new
clocks proved to be more precise in tests and offered a better system for
defining the second. Just as a clock uses the swing of a pendulum to measure
intervals of time, an atomic clock uses the "vibrations" of atoms to
measure time. In earlier atomic clocks, microwaves were used to make the atoms
oscillate. But in the new ones, light is used. The finding is published in
Nature Communications. Link: http://www.nature.com
12 July 2013: Scientists have discovered a second
'blue planet' in the Universe, although this one is decidedly inhospitable and
unlikely to support life. "Blue Planet" is the nickname of Earth as
it appers blue in photographs taken from space. Planet HD 189733b lies some 63
light years beyond our Solar System in the constellation Vulpecula. It has a deep
cobalt blue colour according to data gathered by the Hubble space telescope,
but its azure hue is not due to water but drops of liquid glass. It is the
first time that scientists have been able to calculate the visible colour of an
"exoplanet" beyond our own Solar System. The planet is a gas giant
with temperatures 1,000C or higher. Link: http://iopscience.iop.org
13 July 2013: The US military has unveiled one of its
most-advanced humanoid robots known as Atlas, which was created to assist in
future emergency situations. The 1.9-meter tall, 150-kg Atlas robot, built by
Boston Dynamics, is funded by the Pentagon's Defense Advanced Research Projects
Agency (DARPA).The Atlas also boasts 28 hydraulically-actuated degrees of
freedom, two hands, arms, legs, feet as well as an articulated sensor head that
employs laser beams to measure distances. DARPA also wants to demonstrate that
robots can be made to use tools from screwdrivers to fire trucks, and that
robots can be supervised by people who aren't trained to operate robots. Link: http://www.darpa.mil
14 July 2013: In a world first, Japanese scientists
have grown human liver tissue from stem cells, paving way for alleviating the
critical shortage of donor organs. Takanori Takebe and Hideki Taniguchi at
Yokohama City University showed the generation of vascularised and functional human
liver from human induced Pluripotent Stem Cells (hiPSCs) by transplantation of
in vitro grown liver buds. The study demonstrates a proof-of-concept that organ
bud transplantation offers an alternative approach for treating organ failure
by generating artificial organ and also that liver bud formation can be
mimicked in vitro. The study was published in the journal Nature. Link: http://www.nature.com
15 July 2013: The Hubble space telescope has
discovered a new moon orbiting Neptune, NASA has confirmed. Designated S/2004 N
1, this is the 14th known moon to circle the giant planet. It also appears to
be the smallest moon in the Neptunian system, measuring just 20 km across,
completing one revolution around Neptune every 23 hours. It is so small that
the Voyager spacecraft failed to spot it in 1989 when it passed close by
Neptune and surveyed the planet's system of moons and rings. It was discovered
by US astronomer Mark Showalter while studying rings around Neptune.The new
Neptunian moon is roughly 100 million times dimmer than the faintest star.

16 July 2013: A satellite has detected that 300
billion tonnes of ice is being lost every year from the Antarctic and Greenland
glaciers, dramatically increasing sea levels around the world. The satellite
that detected the melting is Gravity Recovery and Climate Experiment (GRACE).
Dr Bert Wouters and his team compared nine years of satellite data from the
GRACE mission with reconstructions of about 50 years of mass changes to the ice
sheets. The findings underscore the need for continuous satellite monitoring of
the ice sheets to better identify and predict melting and the corresponding
sea-level rise. The study is published in Nature Geoscience. Link: http://www.csr.utexas.edu
17 July 2013: Wild life Conservation and Agro- Rural
Development Foundation, a voluntary organisation and International Veterinary
Students' Association (India) have started a councelling centre in Nagpur for
veterinary students with the aim of helping bright students from poor families.
The center will help the students with processes like international education,
training, research, scholarships and fellowships, passport and visa, reference
letter and so on. This year, five students of Nagpur Veterinary College have
been sent to USA for their higher education. Students who want help can contact

18 July 2013: Scientists from
Aix-Marseille University in France, have discovered the largest viruses ever
discovered, called Pandoraviruses. The name comes from the myth of the
'Pandora's Box'. The virus was first discovered by Dr. Jean-Michel Claverie from
sediment off the coast of Las Cruces, Chile. Second virus of the same kind was
found by the scientists in a pond in Melbourne, Australia. The strain found in
Chile is called Pandoravirus salinus while that found in Australia is called
Pandoravirus dulcis. The new giant viruses are visible with light microscope,
being a full micrometer while typical viruses are maybe 20 to 300 nanometers. The study is published in Science. Link: http://www.sciencemag.org
19 July 2013: An international team
of scientists has discovered a new class of white blood cells that play a
critical role as the first line of defense against harmful microbial
infections. The discovery of these white blood cells, found in human lung and
gut tissues, may lead to better design of vaccines and targeted
immuno-therapies for dieseases such as pneumonia caused by infectious microbes.
T cells are immune cells that circulate around our bodies to scan for cellular
abnormalities and infections.The scientists identified a new subset of DCs
(named CD11b+ DCs), which are essential for activating this response. The study
is published in the journal Immunity. Link: http://www.cell.com
20 July 2013: Biologists from the Japan’s Forestry
and Forest Products Research Institute and Tübingen-based Max Planck Institute
for Developmental Biology have described a tiny new species of nematode from
Fukushima province, Japan, and named it after the German theoretical physicist
Max Planck. The new nematode, called Pristionchus maxplancki, is the first
species to carry the name of the Max Planck. It is a microscopic threadworm
belonging to the genus Pristionchus. The nematode Pristionchus maxplancki which
is only 1 mm long, can change the shape of its mouth depending on its
nourishment. The paper published in Zoological Science. Link: http://www.bioone.org
21 July 2013: European Space Agency/NASA Solar and Heliospheric Observatory,
or SOHO, captured images of a gigantic coronal hole hovering over the Sun's
north pole. Coronal holes are dark, low density regions of the sun's outermost
atmosphere, the corona. They contain little solar material, have lower
temperatures, and therefore, appear much darker than their surroundings.
Coronal holes are a typical feature on the sun, though they appear at different
places and at different times of the sun's activity cycle. The activity cycle
is currently ramping up toward Solar Maximum, predicted for late 2013. During
this portion of the cycle, the number of coronal holes decreases. Link: http://sohowww.nascom.nasa.gov
22 July 2013: Sunetra Gupta, an India-born chemist and physicist has joined

operations in 2022 on Mauna Kea, Hawaii. Link: http://www.tmt.org
24 July 2013: The genome of one of the world's key commercial crops, the
oil palm, has been sequenced. The plant's oil is used in many food and
household products, but has caused controversy because large areas of
rainforest have been cleared to make way for plantations. Through deciphering
the crop's DNA, researchers have identified the genes that could help to
produce a more sustainable crop.The oil from palms has a wide variety of uses
and is found in food, soaps and shampoos and biofuels. But as demand for the
product has grown, rainforests, particularly those in South East Asia, have
suffered. The work is published in Nature. Link: http://www.nature.com
25 July 2013: Rosalind Franklin, a British biophysicist and x-ray
crystallographer helped discover the structure of DNA (Deoxyribo Nucleic Acid)
but controversially missed out on the Nobel prize. Born on July 25, 1920 in
London, Rosalind Franklin was the second child and eldest daughter of her
parents who belonged to an affluent British Jewish family. Franklin's
scientific work lead to X-ray diffraction images of DNA which resulted in the
discovery of the DNA double helix. Besides this Franklin's studies also helped
in the understand the molecular structures of RNA, viruses, coal and graphite. In
April 1958, at the age of 37, Rosalind Franklin died of ovarian cancer. Link: http://www.sdsc.edu
26 July 2013: An Ariane 5 rocket takes off at the French and European
spaceport Guyana Space Centre, near Kourou in French Guiana, today. The rocket
carried two satellites; Alphasat, a telecommunication satellite, and Insat-3D,
a meteorological satellite, India's advanced weather satellite Insat-3D. Though
it had developed some anomalies after the launch, it was corrected these
immediately. The satellite has now been successfully placed in a geosynchronous
orbit. According to Indian Space Research Organisation's statement, Insat-3D
has moved towards its final geostationary orbit and its instruments were
switched on August 8, 2013, which are running smoothly. Link: http://www.isro.org
27 July 2013: UK scientists at
European Space Agency (ESA) have designed a concept mission to land astronauts
on Mars by 2021 , twelve years before NASA expects to send a manned mission to
the Red Planet. The plan envisages a three-person crew journeying to Mars
aboard a small two-part craft. NASA says they will get on Mars at the earliest
by 2033. According to professor Tom Pike, the leader of the London team, the
trip would be the next major step for mankind in space and create a Neil
Armstrong and Buzz Aldrin for the 21st Century. The landing on Mars will be an
extreme ride. European Space Agency's Mars landing module will approach Mars at
22530.8kph. Link: http://sci.esa.int
28 July 2013: India is in the process of increasing
its presence in the Arctic and at "Himadri", India's research lab
located there. Last month, India scored a major diplomatic victory by managing
to swing itself a seat on the Arctic Council as a permanent observer with
support from countries like Norway which are primary members. The 'Seed Vault',
buried deep inside a mountain on Longyerbyen is a testament to that effort. The
'Seed Vault', consists of millions of seeds from across the world, including
India, to be stored for safe-keeping should a disease or disaster strike. The
brainchild of conservationist Cary Fowler, the bank was built in 2008, by the Norway.

29 July 2013: Euclid, the
1.2 metre diameter telescope being built by the European Space Agency (ESA)
will map the shape, brightness and 3D distribution of galaxies and looking back
over three-quarters of the history of the universe. To be launched in 2020,
Euclid's 1.2 metre diameter telescope is the most ambitious mission to date to
map the geometry of the universe. Scientists hope it will help solve key
problems in the understanding the roles played by dark matter and dark energy.
Euclid is optimised to answer one of the most important questions in modern
cosmology: why is the universe expanding, rather than slowing down due to gravitational
attraction. Link: http://sci.esa.int
30 July 2013: Within three years, a telescope as big as a shoe box and
