Water shortage will create far-reaching global security concernsOctober 7th, 2009 WASHINGTON - Water scarcity courtesy climate change will create global security concerns, according to Dr. Rajendra K. Pachauri, chair of the intergovernmental panel on climate change, a co-recipient of the 2007 Nobel Peace Prize.
New soil tester to assess earth's healthOctober 2nd, 2009 WASHINGTON - Our planet has a fever. But global warming's effects on farming and water resources is still a mystery.
Humans may have pushed Earth's system beyond 3 of its biophysical thresholdsSeptember 24th, 2009 WASHINGTON - In a new international research, scientists have determined that human activities have already pushed the Earth system beyond three of the planet's biophysical thresholds, with consequences that are detrimental or even catastrophic for large parts of the world. The research was conducted by 29 European, Australian and US scientists.
'Capturing carbon from air only way to save earth'September 24th, 2009 TORONTO - Capturing carbon directly from the air is the only way to prevent dangerous climate changes, says a pioneering Canadian scientist. University of Calgary scientist David Keith says governments need to earmark more research funding for technologies to capture carbon dioxide in surrounding air to save the planet.
A cosmic but too hot place to stand: Astronomers find first rocky planet outside solar systemSeptember 16th, 2009 Found: Firm place to stand outside solar systemWASHINGTON — Astronomers have finally found a place outside our solar system where there's a firm place to stand — if only it weren't so broiling hot. As scientists search the skies for life elsewhere, they have found more than 300 planets outside our solar system.
Astronomers find first rocky planet outside solar systemSeptember 16th, 2009 WASHINGTON - A group of European astronomers said Wednesday that they had found the first known rocky planet outside the solar system. The find by European Southern Observatory scientists in Garching, Germany, is an important step forward in answering the question of whether humans are alone in the universe, because it is the first of the more than 300 known exoplanets - as planets outside the solar system are known - that is not large and gaseous.
Man-made volcanoes may cool Earth by reflecting sunlight back into spaceAugust 30th, 2009 LONDON - The Royal Society in London seems to be convinced that man-made volcanoes can help stave off climate change, as it is backing research into simulated volcanic eruptions that will spray millions of tons of dust into the air to cool the Earth. This week, the society will call for a global programme of studies into geo-engineering, which can help devise new ways to manipulate the planet's climate to counteract global warming.
Doomed planet: Astronomers find planet so big and close to star it may be killing itselfAugust 26th, 2009 Suicidal planet seems on death spiral into starWASHINGTON — Astronomers have found what appears to be a gigantic suicidal planet. The odd, fiery planet is so close to its star and so large that it is triggering tremendous plasma tides on the star.
NASA's Kepler space telescope detects atmosphere of known giant gas planetAugust 10th, 2009 WASHINGTON - NASA's new exoplanet-hunting Kepler space telescope has detected the atmosphere of a known giant gas planet. The find is based on a relatively short 10 days of test data collected before the official start of science operations.
'Super Earth' has rocky surface, say astronomersAugust 7th, 2009 SYDNEY - European astronomers have said that the smallest planet yet detected outside our Solar System, dubbed 'Super Earth', appears to have a solid surface. According to a report by ABC News, the European team describe the exoplanet CoRoT-7b, a so-called Super-Earth, which has a diameter approximately twice that of Earth.
Humans are damaging the world's oceans, say scientistsJuly 30th, 2009 WASHINGTON - In a new study, scientists have said that there is mounting evidence that human activity is changing the world's oceans in profound and damaging ways. The study was carried out by Professor Mike Kingsford of the ARC Centre of Excellence for Coral Reef Studies and James Cook University and colleague Dr Andrew Brierley of St Andrews University, Scotland.
40th anniversary of Moon landing an opportunity to look forward to future space explorationJuly 22nd, 2009 WASHINGTON - A scientist has said that the 40th anniversary of the Apollo lunar landing is a time to look back and, especially, an opportunity to look forward to future space exploration, including the Moon missions now being planned by NASA and other space agencies. Mark A. Bishop, an associate research scientist with the Tucson-based Planetary Science Institute, made the statement.
Snapshot of Earth's chemical fingerprint may help search for life in the universeJune 12th, 2009 WASHINGTON - In a new study, a group of international scientists took the help of a lunar eclipse to take a snapshot of earth's chemical fingerprint, which could help to identify planets most similar to earth where life may be thriving. The team used some of the world's largest optical and infrared telescopes located at the Roque de los Muchachos Observatory in La Palma (Canary Islands, Spain) to observe light reflected from the moon toward the earth during a lunar eclipse on August 16, 2008.
Broken dwarf planet may have scarred the Moon in early solar systemJune 11th, 2009 London, June 11 (ANI: A new analysis of craters of the Moon has suggested that the shattered remnants of a dwarf planet may have bombarded the inner planets in the early solar system. According to a report in New Scientist, several large impact scars on the moon appear to be around 3.9 billion years old, suggesting that the Earth and other objects of the inner solar system were heavily pounded at that time.
