  • The Spices Board on 5 June 2011 launched a campaign to educate farmers, traders and exporters about aflatoxin, a naturally occurring toxin that degrades spices exported from India. The campaign was launched following rapid alerts issued by the European Union against aflatoxin in nutmeg and mace exported from India.Nutmeg and mace are important spices that find wide application in food industry and medicine, and hence monitoring their quality is of utmost importance. Countries from the EU and West Asia, and South Africa and Japan import large quantities of these products in the raw form and as value-added spice oils and oleoresins.The board launched a nationwide publicity campaign to create awareness on the need to get rid of the toxin. Exporters, scientists from the Indian Institute of Spices Research and Kerala Agricultural University, the board, and educated farmers will address the campaign meetings. In the meetings the major nutmeg- and mace-growing regions of Kerala, Konkan coast and Raigad district of Maharashtra will be focussed upon. 
  • A new report released by the International Energy Agency on 5 June 2011 stated that despite 20 years of effort, greenhouse gas emissions are increasing instead of decreasing. The IEA report revealed that energy-related carbon emissions topped 30 gigatons in 2010 which is 5 percent more than the previous record in 2008. If the emission increases further, it could lead to catastrophic climate shifts affecting global agriculture and water supplies. Moreover, it will set off more frequent and fierce storms besides causing an increase in sea levels that would endanger coastlines.The IEA report was released ahead of the Bonn summit to debate a new global warming accord taking place from 6 June to 17 June 2011. It should be noted that the World Environment Day is celebrated on 5 June 2011 every year. 
  • The century’s longest and darkest lunar eclipse has taken place on june 15 night. The awesome spectacle was visible all over the country, including the national capital.

Apart from opening up the remote sensing sector, the RSDP 2011 will remove restrictions to facilitate more users to get high resolution data for developmental activities. Restrictions as per the earlier 2001 policy, was removed. Now there is no bar on publishing of high resolution, remote sensing data of up to one metre resolution.
  • After 134 flights over three decades, The space shuttle Atlantis’ voyage will close when the final space fly to International Space Station(ISS) from Florida’s Kennedy Space Centre on July 8. The shuttle began its long-career in the 1970s as a successor to the Apollo moon craft and was designed to be the first reusable space craft. The maiden flight in April 1981 by astronauts John Young and Robert Crippen aboard shuttle Columbia formally ushered in the new era with a two-day, six-hour mission and 36 orbits of Earth. Since then, shuttles have flown more than 800 million kilometres -- more than the distance between Earth and Jupiter -- and brought more than 350 people into orbit, launched crucial satellites, ushered in a new era of cooperation in space and built the International Space Station.
AUGUST
  • Scientists achieved a major breakthrough in the fight against Type 1 diabetes by developing a treatment which would save the sufferers from a lifetime of insulin injections.The new treatment was codenamed DiaPep277. It will block the process which causes the body's immune system to attack the pancreas in people with Type 1 diabetes. The treatment will be available in the markets within three years. 
  • Planetary scientists have discovered the closest young star to Earth. An international team carried out a research and showed that the star, named AP Columbae, is the closest so-called pre main sequence star. Scientists used the telescopes in Coonabarabran, Chile, Hawai and California to show that the red-dwarf star AP Columbae is the closest to the Earth. Scientists added that for decades it was believed that young stars only resided in vast star-forming regions like Orion Nebula. These regions are usually hundreds of light years away from Earth. Scientists have carried out accurate, all sky surveys to find young stars much closer to home. 
  • A 10-meter long periscope, indigenously developed for a nuclear reactor at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam and claimed to be the longest in the world, was dedicated to the nation on 22 August.

Chetal. The periscope is the longest in the world and would be used in the Prototype Fast Breeder Reactor to view objects inside the reactor during maintenance. 
  • Scientists at the Lawrence Livermore National Laboratory in California who analysed lunar rock samples, thought to have been derived from the original magma, found that the moon could be about 200 million younger than thought. It is believed that the moon took its birth from a giant impact between a large planet-like object and Earth. The energy of the impact was so high that the moon formed from melted material that was ejected into space and as it cooled down, the magma solidified into different mineral components. The rock they analysed is called ferroan anorthosite, or FAN, and it is believed to be the oldest of the moon's crustal rocks.
  • The Zoological Survey of India will establish five DNA laboratories in Dehradun, Chennai, Kolkata, Hyderabad and Pune with the objective of restraining wildlife poachers. The laboratory set by the country’s premier organisation in zoological research and studies will carry out the DNA test of animals listed under Wildlife Protection Act, in order to keep a tab on poaching of these species. The main aim behind setting DNA test centers is to help the wildlife experts in the investigation of dead animals and body parts smuggled to different countries for therapeutic and spiritual purposes. By DNA test it will also become easy to trace out that the dead animal found was being poached or killed by another animal. 
  • Two teams of astronomers discovered the largest and farthest reservoir of water ever detected in the universe. The water in the reservoir is equivalent to 140 trillion times all the water in the world’s ocean. The water surrounds a huge feeding black hole, called a quasar more than 12 billion light years away. A quasar is powered by an enormous black hole that consumes a surrounding disk of gas and dust. Astronomers studied a quasar called APM 08279+5255. This quasar harbors a black hole 20 billion times more massive than the sun and produces as much as energy as a thousand trillion suns.
  • Scientists at the University of Columbia in New York developed a portable blood test devicewhich can diagnose an infection within minutes. The device could be used effectively to prevent HIV and AIDS. The device is in the form of mChip, costing 1dollar and looks like a credit card.

  • The US space agency NASA said ,the twin satellites blasted off aboard a Delta II rocket on September 10 from Cape Canaveral, Florida on a mission to unveil the inner secrets of the moon, “Trying to understand how the moon formed, and how it evolved over its history, is one of the things we’re trying to address with the Grail mission,” said researcher Maria Zuber of the Massachusetts Institute of Technology.
OCTOBER
  • Scientists identified a new biochemical mechanism, which allows brain tumours to survive and grow. This finding will pave the way for new and effective treatments for some of the most aggressive tumours. An international team, led by the University Hospital of Heidelberg made the discovery. Scientists identified the major role played by kynurenine, in favouring the brain tumour growth and at the same time suppressing anti-tumour immune response. Kynurenine is a by-product of metabolism of essential amino acid tryptophan.
  • Astronomers discovered a mysterious little dwarf planet which is believed to be covered in ice. The planet was nicknamed Snow White. It orbits the Sun as part of the Kuiper belt (the ring of the icy body that orbit the Sun beyond Neptune). The planet is located outside Neptune. Officially known as 2007 OR10, it is actually red, half of its surface is covered by water ice that probably emitted from ancient cryovolcanoes. The planet is red because of the thin layer of the methane. Snow White had broken off long ago from another dwarf planet, called Haumea. 
  • The union government of India decided to ban the use of infertility drug Letrozolethat is mainly recommended for treating Cancer patients. The Ministry of Health and Family Welfare issued a directive to ban the use of Letrozole completely with immediate effect. While banning the drug, the Ministry stated that harmful effects were found in the use of Letrozole. Letrozole is used worldwide for cancer patients but it was being used in India as an infertility drug for a long time. 
  • Australian Scientists created the world’s first drug that can prevent blindness from cataracts. At present, the only treatment available to prevent the blindness from cataracts is to remove surgically the affected eye lens and replace it with a synthetic lens. Cataracts are formed when a protein, known as calpain, clouds the eye lens and impairs vision. This is for the first time that a non-surgical cure for the debilitating condition was discovered.
  • A study conducted jointly by the Institute for Health Metrics and Evaluation, University of Washington, University of Hong Kong and the Public Health Foundation of India (PHFI) found that Avahan successfully slowed the transmission of HIV among the general population. Avahan managed to slow down transmission of HIV by raising the coverage of prevention interventions in high-risk groups like female sex workers, their clients and partners, men who have sex with men (MSM), intravenous drug users and truck drivers. About 100, 000 fresh HIV cases among the general population were averted in India in five years by targeting the most vulnerable section. Avahan was launched in 2003 and received $258 million from the Bill and Melinda Gates Foundation. It complemented the government’s own efforts on HIV prevention. The programme was implemented in four large states — Andhra Pradesh, Karnataka, Maharashtra and Tamil Nadu and 2 small northeastern states of Manipur and Nagaland. These six states were estimated to have the highest HIV prevalence in India in 2003, and a total population of 300 million.

Crews rotate every six months.
  • Scientists discovered two sunken islands west of Australia, in the Indian Ocean, which once formed part of the last link between India and Australia. The two islands were about the size of Tasmania. They were once part of the supercontinent Gondwana and more than 1.5 kilometres underwater. The islands, called micro continents, were formed when India moved away from Australia, 130 million years ago during the Cretaceous period (when dinosaurs roamed the Earth). 
  • Indian scientists succeeded in decoding the genome of the arhar dal, which is also known as pigeon pea. This will help not only in developing new varieties but also in increasing the productivity. Indian Council of Agriculture Research and Banaras Hindu University (BHU) carried out the research. Professor Nagendra Kumar Singh spearheaded the project. In fact, 85 per cent of the world's arhar dal is produced and consumed in India. Therefore, this discovery will help decrease the inflated cost of pulses in India.
  • China launched its unmanned spacecraft, Shenzhou-8 on 1 November 2011. Long March-2F rocket propelled the unmanned spacecraft into orbit in the next step towards China's ambitious plans for a manned space station by 2020. Shenzhou-8 carried an experimental facility developed by German and Chinese scientists. Shenzhou 8 was launched from North Gobi desert in China that entered into the orbit successfully. The mission was considered China's most important since its first manned space flight in 2003. In September 2008, the Shenzhou 7, piloted by three astronauts, carried out China's first spacewalk.
  • Australian senate on 8 November 2011 passed legislation that would impose a carbon tax on the nation’s 500 largest polluters. The government reasoned that it was necessary to control climate change. Australia's largest polluters will now pay 23 Australian dollars for every metric ton of carbon gases they produce. Australia is one of the world's worst greenhouse gas emitters per capita because of its heavy dependence on abundant reserves of coal to generate electricity.

  • China launched a high-speed bullet train in Quingdao, Shandong province. Its speed can reach up to 500 kmph. The train was launched by China’s largest rail vehicle maker, CSR Corp. Ltd. China has the largest network of bullet-train track in the world, with 8000 miles of track. 
  • NASA's Kepler mission on 20 December 2011 discovered the first Earth-size planetsorbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun. The discovery marks the next important milestone in the ultimate search for planets like Earth. Both planets reside in a five-planet system called Kepler-20, approximately 1000 light-years away in the constellation Lyra.
  • The indigenously designed and developed Rustom-1 (medium altitude long endurance unmanned combat aerial vehicle) completed its 8th successful flight. It flew at an altitude of 6,000 ft and at a speed of 90 knots during its 30 minutes flight near Hosur, said a Defence Research and Development Organsiation release. Rustom-1 weighs 661 kg.
  • A team of researchers from NASA’s Kepler Mission discovered a habitable earth-like planet,called Kepler-22b. This newly discovered planet orbits around a sun-like star 600 light years away from the planet earth. The star is located near the constellations of Lyra and Cygnus. The planet is very much similar to earth in key aspects. It has a surface temperature of about 72 degrees Fahrenheit and it is likely to have water and land. 
    The star was categorized as a G5 star. It has a mass and radius smaller than that that of the Sun. It makes the star 25 percent less luminous than the Sun. NASA's Kepler mission confirmed its first planet in the habitable zone, the region where liquid water could exist on a planet’s surface. The new exoplanet has the smallest radius amongst all the planets so far discovered. 
  • The theme of World AIDS Day 2011 was Getting to Zero. Backed by the United Nations the Getting to Zero campaign will run until 2015. The Getting to Zero campaign draws heavily from successful 2010 World AIDS Day’s Light for Rights initiative encompassing a range of vital issues identified by key affected populations. In 2011 the global community committed to focusing on achieving 3 targets: Zero new HIV infections, Zero discrimination and Zero AIDS-related deaths.
  • Green Film Festival was held in Delhi from 6 December to 10 December 2011. Leading environment and wildlife films from across the world were screened as part of the CMS Vatavaran film festival. Biodiversity Conservation was the theme of the festival. 114 films were screened, taking viewers into the diverse geographical realms of planet Earth through the lens of the finest environment and wildlife film-makers. It was a summit for Asian film-makers, special programmes for children throughout the event and discussions on the environment with more than 50 speakers and 300 delegates from 15 different countries. 
  • India successfully test-fired its nuclear capable Agni-I strategic ballistic missile on 1 December 2011 from the test range at Wheeler Island off Odisha coast, as part of the Indian Army's user trial. The trajectory of the missile, which had an operational strike range of 700 km, was tracked by sophisticated radars and electro-optic telemetry stations located along the sea coast and ships positioned near the impact point in the downrange area. Agni-I was developed by Advanced Systems Laboratory (ASL), the premier missile development laboratory of the DRDO in collaboration with Defence Research Development Laboratory (DRDL) and Research Centre Imarat (RCI) and integrated by Bharat Dynamics Limited (BDL), Hyderabad. Agni-I strategic ballistic missile is an indigenously developed surface-to-surface missile. Agni-I can carry payloads up to 1000 kg. It Weighed 12 tonnes.
  • The first Eld’s deer was born via in vitro fertilization in Thailand. The researchers at the Smithsonian Conservation Biology Institute (SCBI) collected eggs, inseminated in vitro with thawed semen to produce embryos and transferred the embryos to a surrogate mother. As a result, a fawn was born on 17 October 2011 at the Khao Kheow Open Zoo in Thailand. Eld's Deer is also known as the Thamin or Brow-antlered Deer. It is an endangered species of deer indigenous to southeastern Asia.
