Adenine 'tails' make tailored anchors for DNA
Researchers from the National Institute of Standards and Technology (NIST), the Naval Research Laboratory (NRL) and the University of Maryland (UMD) have demonstrated a deceptively simple technique for chemically bonding single strands of DNA to gold. view more (2006-12-27)
Discovery of a unique symbiosis between bacteria and a marine worm
Dr. Nicole Dubilier, a scientist in the Molecular Ecology research group of Dr. Rudolf Amann at the Max Planck Institute of Marine Microbiology in Bremen, and her colleagues have discovered a unique symbiosis between bacteria and a marine worm, described in the journal Nature, issue May 17th 2001. The term symbiosis typically evokes an image of... view more... (2001-05-17)
Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth. view more (2008-06-03)
Detox cure for art treasure
Many museums and churches own pieces of art which were treated with toxic pesticides in the past. Between the 1940’s and 80’s, it was quite usual to protect wood against insects and microorganisms with PCP (pentachlorophenol), DDT and lindane. Though the adverse effect was only recognized later: Lindane and PCP evaporate into the air,... view more... (2002-09-09)
Last time carbon dioxide levels were this high: 15 million years ago, scientists report
You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report Oct. 8 in the online edition of the journal Science. view more (2009-10-09)
Learning to trade in carbon dioxide
"You have to be well prepared to enter the emissions trading arena. Otherwise you'll run the same financial risks as on a conventional stock exchange," declares Franzjosef Schafhausen of the German ministry for the environment, who heads the working group on the national climate change program. Poor awareness of the implications of... view more... (2003-12-01)
Ancient global warming episode holds clues to future climate, UH Manoa researcher says
When scientists take Earth's temperature, they usually use thermometers. But when scientists want to figure out Earth's temperature in the past, they have to rely on other tools. view more (2009-07-17)
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)
RAND study: Alternative fossil fuels have economic potential
Alternative sources of fossil fuels such as oil sands and coal-to-liquids have significant economic promise, but the environmental consequences must also be considered, according to a RAND Corporation study issued today. view more (2008-10-08)
Climate protocol may save Amazon region
If Brazil gets a climate protocol, like the Kyoto Protocol for the rich countries, it will be possible to create an incentive for the country to reduce the deforestation of the Amazon region. The Kyoto Protocol targets a reduction of emissions of carbon dioxide and greenhouse gases. In a new study, Martin Persson, in collaboration with Christian... view more... (2004-05-28)
A New Family of Molecules for Self-Assembly: The Carboranes
To be useful in real-world applications, a self-assembled monolayer (SAM) of molecules on a surface must have a stable and controllable geometry. Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability by making SAMs out of different carboranethiol isomers, which are cage-like molecules. view more (2009-03-26)
Marine scientists return from expedition to erupting undersea volcano
Scientists who have just returned from an expedition to an erupting undersea volcano near the Island of Guam report that the volcano appears to be continuously active, has grown considerably in size during the past three years, and its activity supports a unique biological community thriving despite the eruptions. view more (2009-05-06)
Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't. view more (2008-03-12)
1600 Eruption Caused Global Disruption
The 1600 eruption of Huaynaputina in Peru had a global impact on human society, according to a new study of contemporary records by geologists at UC Davis. view more (2008-04-24)
CAT scan reveals inner workings of volcano island
On the ground and in the water, an international team of researchers has been collecting imaging data on the Soufriere Hills Volcano in Montserrat to understand the internal structure of the volcano and how and when it erupts. view more (2008-12-19)
New materials can selectively capture carbon dioxide, UCLA chemists report
UCLA chemists report a major advance in reducing heat-trapping carbon dioxide emissions in the Feb. 15 issue of the journal Science. view more (2008-02-15)
Coral reefs may start dissolving when atmospheric CO2 doubles
Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. view more (2009-03-10)
Study Finds Plenty of Carbon Dioxide Storage Capacity Underground in Kentucky
As concern has grown over the effects of the human release of carbon dioxide (CO2) gas into the atmosphere, so too has research into technologies to manage CO2. view more (2006-10-09)
ESA tests laser to measure atmospheric carbon dioxide
A recent ESA campaign has demonstrated how a technique using lasers could be employed to measure carbon dioxide in the atmosphere. The campaign supports one of the main objectives of the candidate Earth Explorer A-SCOPE mission. view more (2008-12-04)
Titanium dioxide — It slices, it dices ...
Chemists from the National Institute of Standards and Technology (NIST) and Arizona State University have proposed an elegantly simple technique for cleaving proteins into convenient pieces for analysis. view more (2007-04-02)
