Something new under the Sun
That plants grow better if grown in a greenhouse in the correct climate is nothing new. Dutch researcher Rachel van Ooteghem has designed a control system for an improved solar greenhouse that yields more.   view more (2007-01-31)

Solar Contribution To 'Global Warming' Predicted To Decrease
New research on the sun's contribution to global warming is reported in this month's Astronomy & Geophysics. By looking at solar activity over the last 11,000 years, British Antarctic Survey (BAS) astrophysicist, Mark Clilverd, predicts that the sun's contribution to warming the Earth will... view more (2003-10-01)

Greenhouse Gases - Nothing To Blame For?
In the nearest future we may witness global cooling in spite of increasing concentration of greenhouse gases in the atmosphere. That can happen, if the following hypothesis is correct: not the growth of greenhouse gases concentration provokes temperature to rise, but vice versa. It is generally... view more (2004-07-30)

Biodiesel won't drive down global warming
EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel.   view more (2007-04-23)

Despite Britain's weather, the sun always shines on PV
Contrary to popular opinion, Britain's weather is suited to solar power, say researchers at the University of Oxford. In an independent test of the leading types of solar photovoltaic (PV) panels, they are finding out which types of solar panels work best in Britain's often dull and varied climate.... view more (2001-05-24)

At Least Part of Climate Change is Man-Made
Humanity does seem to have been a major contributor to global warming after all. This has been demonstrated by new simulations carried out at the University of Bonn. The Bonn meteorologists used about 30 different models to investigate how the Earth's average annual temperature would have developed... view more (2005-04-13)

Nano surfaces could slash cost of solar energy
Nanotechnologies which can artificially change the optical properties of materials to allow light to be trapped in solar cells could greatly reduce the cost of solar energy.   view more (2005-02-03)

Plastic solar cell efficiency breaks record at WFU nanotechnology center
The global search for a sustainable energy supply is making significant strides at Wake Forest University as researchers at the university's Center for Nanotechnology and Molecular Materials have announced that they have pushed the efficiency of plastic solar cells to more than 6 percent.   view more (2007-04-20)

New isotope molecule may add to Venus' greenhouse effect
Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus.   view more (2007-10-11)

Sun's direct role in global warming may be underestimated, Duke physicists report
At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities.   view more (2005-10-03)

Astrophysicists find fractal image of Sun's 'Storm Season' imprinted on Solar Wind
Plasma astrophysicists at the University of Warwick have found that key information about the Sun's 'storm season' is being broadcast across the solar system in a fractal snapshot imprinted in the solar wind.   view more (2007-05-29)

Link between tropical warming and greenhouse gases stronger than ever, say scientists
New evidence from climate records of the past provides some of the strongest indications yet of a direct link between tropical warmth and higher greenhouse gas levels, say scientists at the University of California, Santa Barbara.   view more (2005-10-14)

Storage of greenhouse gasses in Siberian peat moor
Wet peat moorlands form a sustainable storage place for the greenhouse gas carbon dioxide but are also a source of the much stronger greenhouse gas methane. According to Dutch researcher Wiebe Borren, peat moorlands will counteract the greenhouse effect under the present climatic conditions.   view more (2007-01-31)

Researchers demonstrate 'avalanche effect' in solar cells
Researchers at TU Delft and the FOM Foundation for Fundamental Research on Matter have found irrefutable proof that the so-called avalanche effect by electrons occurs in specific, very small semiconducting crystals.   view more (2008-05-27)

Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr... view more (2004-04-07)

New study: Why solar cells lose potency
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent.   view more (2005-06-20)

New study of solar system speculates about life on other planets
A comprehensive review by leading scientists about our Solar System which speculates on the possibility of life on other planets has been published.   view more (2006-09-13)

The future of solar-powered houses is clear
People could live in glass houses and look at the world through rose-tinted windows while reducing their carbon emissions by 50% thanks to QUT Institute of Sustainable Resources (ISR) research.   view more (2008-04-10)

A New Russian Meteorite?
On Thursday 3 October, residents of the village of Bodaibo in the Irkutsk region of Siberia witnessed the fall of a large glowing object from space. Witnesses saw a large fireball in the sky, followed by a thunder-like sound, a flash of light, and a small earth tremor. Scientists from the Institute... view more (2002-10-04)

Shift toward services industries won't end global warming
The shift toward a service-based economy won't automatically reduce the amount of greenhouse gases (GHS) in the air, a University of Minnesota researcher has found. His research contradicts assumptions about global warming often preferred by some economists and national policy experts.   view more (2006-11-02)

Voyager data may reveal trajectory of solar system
Nearly 30 years after launch, the two Voyager spacecraft are still operational and returning useful data. In their early years they produced some of the first close up images of the large outer planets.   view more (2006-05-31)

Star on a Hubble diet
How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated.   view more (2006-12-12)

NASA Study Finds Warmer Future Could Bring Droughts
NASA scientists may have discovered how a warmer climate in the future could increase droughts in certain parts of the world, including the southwest United States.   view more (2007-02-14)

Industrial collaboration on Uppsala solar cells
In five years' time, the first factory-made solar cell panels developed in Uppsala will be on the market. This can become a reality thanks to a new agreement between three major companies, two investment funds, and a spin-off company from the Uppsala University Ã"¦ngström Solar Center.... view more (2003-06-27)

Winds of 320 000 kilometres per hour on the Sun
The SUMER instrument on the ESA-NASA SOHO spacecraft has measured amazing wind speeds during its observations of the Sun. It sets a new record in its examination of two loops of gas arching in the solar atmosphere, where NASA`s TRACE satellite spotted bright blobs of gas. Shifts in the wavelength... view more (2002-05-17)
