Piecing together the cyanobacteria puzzle
Blue green algae are significant species in the global carbon cycle because they transform nitrogen gas from the atmosphere into a useable nutrient, enabling photosynthesis in nutrient-poor waters.   view more (2007-07-11)

Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide   view more (2006-04-13)

The Universe, seen under the Gran Sasso mountain, seems to be older than expected
Some nuclear fusion reactions inside stars occur more slowly than we thought and, as a consequence, stars themselves, as well as galaxies and the entire universe are a bit older than expected. This is what comes out from the last results of Luna experiment (Laboratory for Underground Nuclear... view more (2004-05-13)

Tracing poisonous gases in the ocean
About one and a half years ago the Deutsche Forschungsgemeinschaft assigned the Research Center Ocean Margins to the University of Bremen. In the future the Center shall act as a center of excellence in the field of marine research. Having completed its building-up phase today the first marine... view more (2003-01-21)

Confirmed - deforestation plays critical climate change role
Dr Pep Canadell, from the Global Carbon Project and CSIRO Marine and Atmospheric Research, says today in the journal Science that tropical deforestation releases 1.5 billion tonnes of carbon each year into the atmosphere.   view more (2007-05-14)

Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health.   view more (2006-04-03)

Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today.   view more (2007-12-11)

Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.   view more (2008-10-02)

Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the... view more (2006-03-09)

New Centre For Satellite Observation Established In North Wales
North Wales is to play a major role in using information from earth-orbiting satellites to improve predictions of future environmental change. The School of Ocean Sciences at University of Wales, Bangor will be part of a national Centre of Excellence in Earth Observation which is to be established... view more (2002-10-17)

Metal-containing compounds show promise as HIV weapon
A molecule consisting of two "cages" of metallic atoms bound to carbon has shown great promise in preliminary tests of becoming a new weapon in the anti-HIV arsenal, researchers at UT Southwestern Medical Center report.   view more (2005-11-01)

Fertility experts urge clinics to consider 'natural cycle' IVF instead of routine use of ovarian stimulants
A team of UK fertility experts wants IVF clinics to consider taking advantage of a woman's natural cycle during infertility treatment instead of routinely using drugs to stimulate ovaries into producing extra eggs. A study published today (Wednesday 31 January) in Europe's leading reproductive... view more (2001-01-28)

Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common... view more (2001-06-21)

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... view more (2002-09-09)

Ocean's 'twilight zone' may be a key to understanding climate change
A major study sheds new light on the role of carbon dioxide once it's transported to the oceans' depths. The research indicates that instead of sinking, carbon dioxide is often consumed by animals and bacteria and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below... view more (2007-04-30)

IGBP calls for better observation of Earth's "Achilles' heels"
Monitoring the most sensitive "hotspots" of the Earth is an important way of assessing the health of our planet and predicting our future, said IGBP (International Geosphere-Biosphere Programme) scientists speaking at the Earth Observation Summit in Washington last week. The summit was... view more (2003-08-06)

Carbon offset warning from international team of scientists
Leading marine scientists from across the world have issued a warning that it is too early to sell carbon offsets from ocean iron fertilisation.   view more (2008-01-11)

UA scientists part of Supreme Court case on carbon dioxide emissions
Four faculty members from The University of Arizona in Tucson were part of an amicus curiae brief supporting the plaintiff in today's historic U.S. Supreme Court decision on carbon dioxide emissions and climate change.   view more (2007-04-03)

Improved wettability of carbon nanotubes opens the door to new possibilities
Carbon nanotubes have long been touted as the wonder material of the future but their wonder properties can also be their downfall. The non reactive nature of carbon nanotubes means they can be difficult to incorporate into other materials for real world applications.   view more (2007-11-26)

Ocean growing more acidic faster than once thought
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide.   view more (2008-11-25)

Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the... view more (2004-02-25)

Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates.   view more (2006-02-17)

New earth observation centres announced
Two new centres which will use satellites and models to help forecast earthquakes and the effects of carbon in climate change were announced (Wednesday 17 October) by Lord Sainsbury, Science & Innovation Minister. Said Lord Sainsbury, " I am delighted to announce that the Natural... view more (2001-10-19)

Another type of nanotube, a how-to guide to making bamboo-structured carbon nanotubes
Nanotechnology is area if science that has recently captured the attention of people all around the world. At the heart of the nanotechnology revolution are carbon nanotubes, amazing materials with astonishing properties. They have applications in most fields, with new possibilities emerging... view more (2007-11-26)

High Value Semiconducting Carbon Nanotubes
Moore's Law states that the number of transistors on a chip doubles every eighteen months. However current silicon technologies are approaching the limits imposed by quantum mechanics, which will stop Moore's Law in its tracks within 20 years.
