Radio Telescopes Reveal Unseen Galactic Cannibalism
Radio-telescope images have revealed previously-unseen galactic cannibalism -- a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies. Astronomers have long suspected that the extra-bright cores of spiral galaxies called Seyfert galaxies are powered by... view more (2008-06-24)
North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels. view more (2005-10-11)
Chandra discovers light echo from the Milky Way's Black Hole
Like cold case investigators, astronomers have used NASA's Chandra X-ray Observatory to uncover evidence of a powerful outburst from the giant black hole at the Milky Way's center. view more (2007-01-11)
CO2 emissions increasing faster than expected
Carbon dioxide emissions from fossil fuels - the principal driver of climate change - have accelerated globally at a far greater rate than expected over recent years. view more (2007-05-22)
The fight for the best quantum bit (qubit)
Our results give us, for the first time, the possibility to understand the interaction between just two electrons placed next to each other in a carbon nanotube. view more (2008-06-25)
Unexpected growth in atmospheric CO2
A team of scientists has found that atmospheric carbon dioxide (CO2) growth has increased 35 percent faster than expected since 2000. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2007-10-23)
Magnet Made Of Pure Carbon
All known magnets contain metals and so far scientists believed that non-metallic material could not behave like a strong magnet. However, at the end of 20th century, some organic substances with strong magnetic properties were found, but they were magnetic only at very low temperatures, just above... view more (2001-10-24)
Carbon nanotube absorption measured in worms, cancer cells
University of Michigan researchers have discovered how to measure the absorption of multi-walled carbon nanoparticles into worms and cancer cells, a breakthrough that will revolutionize scientists' understanding of how the particles impact the living environment. view more (2006-03-29)
Monster black holes grow after galactic mergers
An analysis of the Hubble Space Telescope's deepest view of the universe offers compelling evidence that monster black holes in the centers of galaxies were not born big but grew over time through repeated galactic mergers. view more (2006-01-11)
Nutrition and heredity are genetically linked
A challenging goal in biology is to understand how the principal cellular functions are integrated so that cells achieve viability and optimal fitness under a wide range of nutritional conditions. view more (2007-05-17)
Plants' role in global warming re-examined in ORNL Science paper
Estimates of increased plant respiration in response to higher global temperatures may be somewhat overstated as they have not taken into account plants' ability to adjust to changing conditions, according to researchers from Oak Ridge National Laboratory. view more (2006-05-02)
Ancient Oak Trees Help Reduce Global Warming, MU Study Finds
The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers from the University of Missouri have discovered that nature has been lending a hand. Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in... view more (2008-06-30)
New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate. view more (2007-12-12)
Cosmic thermostats provide clue to 30 year old astronomy puzzle (Embargoed until 1900 hrs London time Wednesday 17 July 2002)
A cosmic phenomenon involving pockets of hot gas in space which appear not to cool down has been puzzling astronomers for three decades. Now new research by Dr Christian Kaiser at the University of Southampton and Professor Marcus Brüggen of the International University Bremen, Germany, shows... view more (2002-07-16)
Astronomers shed surprising light on our galaxy's black hole
In the most comprehensive study of Sagittarius A (Sgr A), the enigmatic supermassive black hole in the center of the Milky Way Galaxy, astronomers - using nine ground and space-based telescopes including the Hubble Space Telescope and the XMM-Newton X-ray Observatory - have... view more (2006-01-11)
Chemists Find Too Much Air Sticks Precious Carbon Footballs Together
Ever since researchers discovered a form of carbon consisting of a class of miniature, football-like structures known as fullerenes, they have been racing to use the unique structures in all kinds of novel ways from drug delivery to nanotechnology. However, chemists at the Universities of Warwick... view more (1998-12-15)
Some ethnic groups more susceptible to adverse drug reactions
Some ethnic groups may be more susceptible to adverse drug reactions, finds a study published on bmj.com today. view more (2006-05-05)
Identification of carbon dioxide receptors in insects may help fight infectious disease
Mosquitoes don't mind morning breath. They use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria, yellow fever, and West Nile encephalitis. view more (2006-12-14)

Hungry microbes share out the carbon in the roots of plants
Sugars made by plants are rapidly used by microbes living in their roots, according to new research at the University of York, creating a short cut in the carbon cycle that is vital to life on earth. view more (2007-10-19)
From black box to optimized plant
In times gone by, something complex as a steam engine was hardly understood by amateurs. They perceived it as a black box and thought it should simply work. There are basic similarities in today's factory planning and plant design: Something goes in at one end in a continuous flow (steam, wood... view more (2003-05-22)
UN body asks Lund Researchers to investigate new type of carbon sink
Trade in emission rights is intended to reduce global emissions of greenhouse gases. Countries with natural carbon sinks—areas that absorb more carbon dioxide than they give off—can ‘trade off’ that resource in return for their commitments to reduce emissions. Thus far this... view more (2001-11-09)
Studying rivers for clues to global carbon cycle
In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part... view more (2008-02-11)
Obesity may keep some women from getting screened for breast, cervical cancer
A review of cancer screening studies shows that white women who are obese are less likely than healthy weight women to get the recommended screenings for breast and cervical cancer, according to researchers at the University of North Carolina at Chapel Hill's School of Public Health. view more (2008-03-25)
Neutron stars join the black hole jet set
NASA's Chandra X-ray Observatory has revealed an X-ray jet blasting away from a neutron star in a binary system. view more (2007-06-28)
