Black Holes Lead Galaxy Growth, New Research Shows
Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores.   view more (2009-01-07)

Jupiter-like Planets Could Form Around Twin Suns
Life on a planet ruled by two suns might be a little complicated. Two sunrises, two sunsets. Twice the radiation field.    view more (2009-01-06)

Researchers make breakthrough in the production of double-walled carbon nanotubes
In recent years, the possible applications for double-walled carbon nanotubes have excited scientists and engineers, particularly those working on developing renewable energy technologies.   view more (2008-12-23)

Where did Venus's water go?
Venus Express has made the first detection of an atmospheric loss process on Venus's day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side.   view more (2008-12-19)

Biggest breach of Earth's solar storm shield discovered
Earth's magnetic field, which shields our planet from particles streaming outward from the Sun, often develops two holes that allow the largest leaks, according to researchers sponsored by NASA and the National Science Foundation.   view more (2008-12-17)

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)

Wind, water and sun beat biofuels, nuclear and coal for clean energy, Stanford researcher says
The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental... view more (2008-12-11)

Astronomers use ultra-sensitive camera to measure size of planet orbiting star
A team of astronomers led by John Johnson of the University of Hawaii's Institute for Astronomy has used a new technique to measure the precise size of a planet around a distant star. They used a camera so sensitive that it could detect the passage of a moth in front of a lit window from a distance... view more (2008-12-11)

NASA's Swift Looks to Comets for a Cool View
NASA's Swift Gamma-ray Explorer satellite rocketed into space in 2004 on a mission to study some of the highest-energy events in the universe.   view more (2008-12-04)

Solar-Powered Sea Slugs Live Like Plants
The lowly sea slug, "Elysia chlorotica," may not seem like the most exciting of creatures, but don't be fooled: it behaves like a plant and is solar-powered, says a Texas A&M University biologist who has been studying these tiny creatures for the past decade and, along with... view more (2008-11-26)

Jupiter's rocky core bigger and icier, model predicts
Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms.   view more (2008-11-26)

Tiny protein provokes healthy bonding between cells
In human relationships, a certain "spark" often governs whether we prefer one person to another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that... view more (2008-11-26)

Boosting the power of solar cells
New ways of squeezing out greater efficiency from solar photovoltaic cells are emerging from computer simulations and lab tests conducted by a team of physicists and engineers at MIT.   view more (2008-11-25)

Beta Pictoris planet finally imaged?
A team of French astronomers using ESO's Very Large Telescope have discovered an object located very close to the star Beta Pictoris, and which apparently lies inside its disc.   view more (2008-11-24)

Mars Express observes aurorae on the Red Planet
Scientists using ESA's Mars Express have produced the first crude map of aurorae on Mars. These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by Mars's crustal rocks.   view more (2008-11-24)

Los Alamos Observatory Fingers Cosmic Ray 'Hot Spots'
A Los Alamos National Laboratory cosmic-ray observatory has seen for the first time two distinct hot spots that appear to be bombarding Earth with an excess of cosmic rays. The research calls into question nearly a century of understanding about galactic magnetic fields near our solar system.    view more (2008-11-24)

Mystery of missing hydrogen
Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life.   view more (2008-11-24)

Researchers make new electronics -- with a twist
They've made electronics that can bend. They've made electronics that can stretch. And now, they've reached the ultimate goal -- electronics that can be subjected to any complex deformation, including twisting.   view more (2008-11-20)

Scientists Discover New Planet Orbiting Dangerously Close to Giant Star
A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun.   view more (2008-11-19)

Carbon dioxide already in danger zone, warns study
A group of 10 prominent scientists says that the level of globe-warming carbon dioxide in the air has probably already reached a point where world climate will change disastrously unless the level can be reduced in coming decades.   view more (2008-11-19)

Precise measurement of phenomenon advances solar cell understanding
Researchers at Washington University in St. Louis have shed light on a basic process that could improve future solar cells.    view more (2008-11-19)

Just Scratching the Surface: New Technique Maps Nanomaterials as They Grow
Researchers at Rensselaer Polytechnic Institute have developed a measurement technique that will help scientists and companies map nanomaterials as they grow.   view more (2008-11-05)

Surgical Removal of Small Colon Polyps is Costly and Unnecessary
Polypectomy (the surgical removal of polyps by colonoscopy) of small polyps found during CT colonography is costly and unnecessary according to a study performed at the University of Wisconsin School of Medicine and Public Health in Madison, WI.    view more (2008-11-04)

Solar Power Game-Changer: "Near Perfect" Absorption of Sunlight, From All Angles
Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy.   view more (2008-11-04)

New spaceship force field makes Mars trip possible
According to the international space agencies, "Space Weather" is the single greatest obstacle to deep space travel. Radiation from the sun and cosmic rays pose a deadly threat to astronauts in space.   view more (2008-11-04)
