The next great earthquake
The 2004 Sumatra-Andaman earthquake and resulting tsunami are now infamous for the damage they caused, but at the time many scientists believed this area was unlikely to create a quake of such magnitude.   view more (2007-03-23)

Travelers can avoid jet lag by resetting their body clocks
A simple, at-home treatment - a single light box and the over-the-counter drug melatonin - allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones.   view more (2005-11-02)

Volcano-like tremors detected deep within Earth's crust near San Andreas
Tremors within the Earth are usually-but not always-related to the activity of a volcano. Now, such vibrations have been recorded nowhere near a volcano, but at a geologic observatory at the San Andreas Fault.   view more (2006-04-13)

DNA: Bacteria's survival ration
The ubiquitous bacteria E. coli rank among nature's most successful species for lots of reasons, to which biologists at the University of Southern California have added another: in a pinch, E. coli can feast on the DNA of their dead competitors.   view more (2006-05-30)

Study of 2004 tsunami forces rethinking of giant earthquake theory
The Sumatra-Andaman earthquake of Dec. 26, 2004, was one of the worst natural disasters in history, largely because of the devastating tsunami that followed.   view more (2006-03-06)

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)

San Andreas Fault Observatory at Depth reveals new insights into the 'earthquake machine'
The San Andreas Fault Observatory at Depth (SAFOD)-the first underground observatory to provide physical samples and real-time seismological data from deep inside an active fault zone-is yielding surprising new clues about the origin of earthquakes.   view more (2005-12-06)

Hunt for planets outside solar system uncovers a small one
Perhaps edging closer to finding planets that harbor life, astronomers have discovered the smallest planet yet identified outside our solar system.   view more (2006-01-26)

Prelude to an Earthquake?
A geophysicist from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has identified possible seismic precursors to two recent California earthquakes, including the 1989 Loma Prieta earthquake that wreaked havoc throughout the Bay Area.   view more (2005-12-12)

Astronomers find first habitable Earth-like planet
Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water.   view more (2007-04-25)

Chronic oil pollution takes toll on seabirds along South American coast
Chronic oil pollution has been a long-standing problem along a 4,200-mile stretch of coast from southern Brazil to northern Argentina.   view more (2006-02-01)

Sediment layer may forecast greatest earthquakes
Researchers at Yale and the University of Washington report that great earthquakes, like the 2004 Sumatra earthquake, may be caused by the build up of sediment on top of subduction zones, suggesting a new way to forecast these most severe earthquakes.   view more (2006-01-31)

Picky female frogs drive evolution of new species in less than 8,000 years
Picky female frogs in a tiny rainforest outpost of Australia have driven the evolution of a new species in 8,000 years or less, according to scientists from the University of Queensland, the University of California, Berkeley, and the Queensland Parks and Wildlife Service.   view more (2005-10-31)

No safe ground for life to stand on during world's largest mass extinction
The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today.   view more (2005-12-02)

Red Tide causes sea turtle die-off in El Salvador
A "Red Tide" event that occurred off the coast of El Salvador late last year directly caused the deaths of some 200 sea turtles.   view more (2006-03-24)

Forests damaged by Katrina may contribute to global warming
Researchers led by biologist Jeffrey Chambers of Tulane University have determined that the losses inflicted by Hurricane Katrina on Gulf Coast forest trees are enough to cancel out a year's worth of new tree biomass (trunks, branches and foliage) growth in other parts of the country.   view more (2007-11-16)

Astronomers link old stars and mysterious cosmic explosions
Cosmic gamma-ray bursts, the most powerful explosions in the universe, have the extreme brilliance of a billion billion Suns and occur several times a day.   view more (2005-12-15)

Sediment could be a major factor in biggest subduction zone earthquakes
The most powerful earthquakes - such as those that shook Indonesia in 2004, Alaska in 1964, Chile in 1960 and the Pacific Northwest in 1700 - occur in subduction zones, areas of the sea floor just offshore where two tectonic plates meet and one dives beneath the other.   view more (2006-01-31)

Fewer Deaths than 2004, but Earthquakes Still Kill Nearly 90,000 in 2005
Although there were fewer deaths worldwide in 2005 due to earthquakes, more than 89,353 casualties were reported, according to the U.S. Geological Survey (USGS) and confirmed by the United Nations Office for Coordination of Humanitarian Affairs (OCHA).   view more (2006-01-16)

Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells.   view more (2006-02-17)
