Scientists uncover solar cycle, stratosphere and ocean connections
Subtle connections between the 11-year solar cycle, the stratosphere, and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research appearing this week in the journal Science. view more (2009-08-28)
Moon and Earth Formed out of Identical Material
According to the «Giant Impact» theory the moon was formed by a collision between a proto-earth and a smaller planet. In the October 12 issue of Science, ETH researchers present results showing that the composition of the oxygen isotopes of the moon and the earth are identical. This is a strong indication that the proto-earth and the planet with... view more... (2001-10-11)
Life elsewhere in Solar System could be different from life as we know it
The search for life elsewhere in the solar system and beyond should include efforts to detect what scientists sometimes refer to as "weird" life -- that is, life with an alternative biochemistry to that of life on Earth -- says a new report from the National Research Council. view more (2007-07-09)
Stable power supply thanks to wind turbines
Wind turbines can help keep the voltage in the electricity network at a constant level. The power electronics in the turbines can effectively correct peaks and dips in the mains voltage. This is the conclusion reached by NWO-funded researchers. Modern wind turbines are a good means of coping with fluctuations in the mains voltage. Such... view more... (2001-10-08)
Wobbly planets could reveal Earth-like moons
Moons outside our Solar System with the potential to support life have just become much easier to detect, thanks to research by an astronomer at University College London (UCL). view more (2008-12-12)
NOAA: Sunspot is harbinger of new solar cycle, increasing risk for electrical systems
A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM transactions, showed signs it was on its way late Thursday when the cycle's first sunspot appeared in the sun's Northern Hemisphere, NOAA scientists... view more...

Features of early Martian environment and presence of water drive search for life forms
olar energy and winds, collisions with asteroids and comets, and changing magnetic fields have all altered the environment of Mars, a planet that may have been able to support life during its history. view more (2009-04-17)
Silicon Thin-Film Solar Cells Gaining In Efficiency
An important goal of modern energy research is to directly convert sunlight into electricity at low cost. Silicon thin-film solar cells promise comparatively lower costs than conventional solar cells. However, to become a mass product of the future, the efficiencies of large-area modules must climb from currently about 6 to 7 percent to 10 percent... view more... (2002-08-08)
Evidence of liquid water in comets reveals possible origin of life
Comets contained vast oceans of liquid water in their interiors during the first million years of their formation, a new study claims. view more (2009-07-31)
IBEX satellite finds ribbon-like structure at edge of heliosphere
The invisible structures of space are becoming less so, as scientists look out to the far edges of the solar wind bubble that separates our solar system from the interstellar cloud through which it flies. view more (2009-10-16)
Connections among solar cycle, stratosphere and ocean discovered
Subtle connections between the 11-year-solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research results appearing this week in the journal Science. view more (2009-08-28)
Flower power
A plastic "energy flower'' that collects solar and wind energy that can then be used to power appliances in the home for free has won a Northumbria University student a top award. Paul Richardson, a third year design student, won a £1,750 Design International Attachment Award from the RSA (Royal Society for the encouragement of Arts,... view more... (2002-05-24)
Earliest meteorites provide new piece in planetary formation puzzle
Researchers trying to understand how the planets formed have uncovered a new clue by analysing meteorites that are older than the earth. view more (2005-09-20)
Nanopillars Promise Cheap, Efficient, Flexible Solar Cells
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have demonstrated a way to fabricate efficient solar cells from low-cost and flexible materials. view more (2009-07-10)
Tiny crystals promise big benefits for solar technologies
Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials that previously thought. view more (2006-01-05)
Renewable energy wrecks environment
Renewable does not mean green. That is the claim of Jesse Ausubel of the Rockefeller University in New York. Writing in Inderscience's International Journal of Nuclear Governance, Economy and Ecology, Ausubel explains that building enough wind farms, damming enough rivers, and growing enough biomass to meet global energy demands will wreck the... view more...

NASA Sees Solar Eclipse in a Different Light
NASA is offering the public a front row seat for the total solar eclipse on Wednesday, March 29 thanks to a partnership with the University of California at Berkeley and San Francisco's Exploratorium. view more (2006-03-29)
Solar cycle linked to global climate, drives events similar to El Nino, La Nina
Establishing a key link between the solar cycle and global climate, new research led by the National Center for Atmospheric Research (NCAR) shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Nina and El Nino events in the tropical Pacific Ocean. view more (2009-07-17)
Neutrinos galore - an old problem, a new challenge - The Physics Congress 2002
Neutrinos - probably the most baffling forms of known matter in the Universe - are setting new challenges for physicists, just as one long-running mystery seems close to being resolved. On Wednesday 10 April, John Bahcall from the Institute for Advanced Study in Princeton, USA, will tell the Institute of Physics Congress in Brighton how we are at... view more... (2002-04-02)
New Carbon Material Shows Promise of Storing Large Quantities of Renewable Electrical Energy
Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar... view more...
