Astronomers discover distant, icy Earth-like planet
An international team of astrophysicists has discovered a new planet five times the size of Earth, the smallest extrasolar planet revealed to date outside of our solar system.   view more (2006-01-27)

UBC study may solve age-old mystery of missing chemicals from Earth's mantle
Observations about the early formation of Earth may answer an age-old question about why the planet's mantle is missing some of the matter that should be present, according to UBC geophysicist John Hernlund.   view more (2007-12-06)

A Warm South Pole? Yes, on Neptune!
An international team of astronomers using ESO's Very Large Telescope has discovered that the south pole of Neptune is much hotter than the rest of the planet. This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years.   view more (2007-09-19)

Meteorites are rich in the building blocks of life, claims new research
Amino acids that are the building blocks of life have been found in their highest ever concentration in two ancient meteorites which crashed to Earth millions of years ago, scientists claim today.   view more (2008-03-14)

It will be possible to predict earthquakes from space
The scientists of the Department of Physics, Moscow State University, have proposed to predict earthquakes by measuring polarization of the solar light that is reflected from the surface of the Earth. The small and cheap equipment, which the scientists have designed, can be placed on meteorological satellites. Polarization of solar light at... view more... (2001-01-17)

Astronomers use Hubble to 'weigh' Dog Star's companion
For astronomers, it's always been a source of frustration that the nearest white-dwarf star is buried in the glow of the brightest star in the nighttime sky. This burned-out stellar remnant is a faint companion of the brilliant blue-white Dog Star, Sirius, located in the winter constellation Canis Major.   view more (2005-12-13)

Earthquakes Happen at Full Moon
Russian physicists have found that flashes of neutron radiation from the Earth surface are bound to increasing in seismic activity. They believe that this phenomenon can be used as a novel kind of earthquake foreboding. The researchers of the Department of Cosmic Radiation of the Research Institute of Nuclear Physics at Moscow State University... view more... (2001-02-02)

European Space Agency to probe asteroid blind spot
In the past five weeks two asteroids have passed close by Earth, at distances of 1.2 and 3 times the distance to the Moon. Another asteroid has recently been shown to be on course for a collision with Earth in 2880. Monitoring known asteroids allows astronomers to predict which may collide with Earth. But that is only true for the asteroids we... view more... (2002-04-15)

UGA researchers propose new hypothesis on the evolution of hot springs microorganisms
Since their discovery in the late 1970s, microorganisms known as archaea have fascinated scientists with their ability to thrive where no other life can — in conditions that are extremely hot, acidic or salty.   view more (2006-06-06)

Seismic images show dinosaur-killing meteor made bigger splash
The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.   view more (2008-01-24)

Blue light used to harden tooth fillings stunts tumor growth
A blue curing light used to harden dental fillings also may stunt tumor growth, Medical College of Georgia researchers say.   view more (2008-06-25)

Study plunges standard theory of cosmology into crisis
As modern cosmologists rely more and more on the ominous "dark matter" to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists.   view more (2009-05-06)

No Core In Volcanoes
A hot debate in the Earth Sciences is finally resolved in this week's issue of Nature. Researchers from the Department of Earth Sciences at Bristol University show that large volcanoes do not contain material from the Earth's core. This overturns previous theories that conflicted with models of how the Earth's magnetic field is sustained. The... view more... (2004-01-12)

Magnetic Storms And Earthquakes
For years scientists have been studying the impact of different geophysical fields on the earthquakes occurrence. It has been assumed that the fields, generated due to the solar activity, earth flows fluctuations, the Earth`s speed of rotation and even the launch of magnetohydrodynamic generators affect the strained state of the earth`s crust,... view more...

Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide.   view more (2009-10-15)

Scientific breakthrough will help protect astronauts and spacecraft
A breakthrough by a team of British, US and French scientists will help protect astronauts, spacecraft and satellites from radiation hazards experienced in space.   view more (2005-09-08)

Astronomers find grains of sand around distant stars
In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. The report will be published online this week by the journal Nature.   view more (2008-03-13)

New Models of Weather Pattern
For a mathematician, Joseph Biello spends a lot of time thinking about the weather. But the UC Davis assistant professor isn't looking out the office window. He is using mathematical theory to build a model of the Madden-Julian Oscillation, a tropical weather pattern that influences drought and rainfall in the western U.S.   view more (2005-12-12)

Mathematicians find way to improve medical scans
Mathematicians at the University of Liverpool have found that it is possible to gain full control of sound waves which could lead to improved medical scans, for technology such as ultra sound machines.   view more (2008-01-08)

How to deflect an asteroid
STRANGE as it may seem, averting Armageddon isn`t the top priority for most asteroid hunters. They`d be happy just to know where the rock that could wipe out life on Earth will come from. But an astronomer in Italy thinks he can save the world-with space-based missiles.         By the end of the decade,... view more... (2002-02-13)
