Physical activity more likely to prevent breast cancer in certain groups
Physically active women are 25 per cent less likely to get breast cancer, but certain groups are more likely to see these benefits than others, finds a review of research published online ahead of print in the British Journal of Sports Medicine. view more (2008-05-13)
Mega Eruption of Yellowstone's Southern Twin
North America isn't the only continent that's experienced super-colossal volcanic eruptions in the recent geologic past. view more (2006-03-29)
Volcanoes cool the tropics, say researchers
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics-but suggest that such effects may have been masked in the 20th century by rising global temperatures. view more (2009-01-06)
UB Geologists to Help Communicate the Dangers of Colombian Volcano
During the past decade, residents of Pasto, Colombia, and neighboring villages near Galeras, Colombia's most dangerous volcano, have been threatened with evacuation, but compliance varies. view more (2009-07-01)
Natural climate change may be larger than commonly thought
A new study of climate in the Northern Hemisphere for the past 2000 years shows that natural climate change may be larger than generally thought. This is displayed in results from scientists at the Stockholm University, made in cooperation with Russian scientists, which are published in Nature on 10 Feb 2005. view more (2005-02-09)
New, hands-on science demos teach young students how volcanoes 'blow their tops,' spew lava
A popular volcano demonstration in grade school science class rivets students' attention as it spews bubbly liquid over a tabletop, but it comes up short in explaining all the ways that volcanoes form and evolve. view more (2006-10-25)
A hidden drip, drip, drip beneath Earth's surface
There are very few places in the world where dynamic activity taking place beneath Earth's surface goes undetected. view more (2009-05-27)
Tiny tremors and earthquakes provide intriguing clues about seismic activity, study finds
The elusive science of earthquake prediction has been reinvigorated in recent years with the discovery of "non-volcanic tremors"—faint vibrations that originate deep inside active fault zones. view more (2006-07-13)
How much are you really exercising?
People struggling with obesity often underestimate how many calories they are actually consuming, which can hinder weight loss efforts. It should follow that the same person would overestimate the amount of exercise they're doing, right? view more (2008-10-06)
CU-Boulder tracks movements of ancient Central Americans using satellites, video-game technology
Satellite imagery meshed with video-game technology is allowing University of Colorado at Boulder and NASA researchers to virtually "fly" along footpaths used by Central Americans 2,000 years ago on spiritual pilgrimages to ancestral cemeteries. view more (2007-01-04)
Calculations favor reducing atmopshere for early Earth
Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth's atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor. view more (2005-09-08)
Sexual pleasure improves after hysterectomy
Many women are concerned that hysterectomy may affect their sexual attractiveness, but a study in this week's BMJ finds that sexual pleasure improves after hysterectomy. Researchers in the Netherlands compared the effects of three types of hysterectomy (vaginal, subtotal abdominal, and total abdominal hysterectomy) on the sexual wellbeing of 413... view more...

Did death-dealing cyanobacteria cause the mass deaths of Messel?
In 1875 the remains of a prehistoric crocodile were found in the brown coal mine at Messel near Darmstadt; since then a large number of well preserved fossils have also been discovered. Palaeontologists have long puzzled over what could have been the reason for this annihilation of so many creatures. In the latest issue of the Pal'¤ontologische... view more... (2004-11-17)
Ocean's journey towards the center of the Earth
A Monash geoscientist and a team of international researchers have discovered the existence of an ocean floor was destroyed 50 to 20 million years ago, proving that New Caledonia and New Zealand are geographically connected. view more (2009-03-05)
Obsidian 'trail' provides clues to how humans settled, interacted in Kuril Islands
Archaeologists have used stone tools to answer many questions about human ancestors in both the distant and near past and now they are analyzing the origin of obsidian flakes to better understand how people settled and interacted in the inhospitable Kuril Islands. view more (2009-06-23)
Tremors on southern San Andreas Fault may mean increased earthquake risk
Increases in mysterious underground tremors observed in several active earthquake fault zones around the world could signal a build-up of stress at locked segments of the faults and presumably an increased likelihood of a major quake, according to a new University of California, Berkeley, study. view more (2009-07-10)
Geologists discover signs of volcanoes blowing their tops in the deep ocean
A research team led by the Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. view more (2008-06-26)
Mars meteorite similar to bacteria-etched earth rocks
A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria. view more (2006-03-24)
Venus mission will hold surprises says U. of Colorado planetary scientist
University of Colorado at Boulder planetary scientist Larry Esposito, a member of the European Space Agency's Venus Express science team, believes the upcoming mission to Earth's "evil twin" planet should be full of surprises. view more (2005-11-03)
Higher levels of common daily activity associated with lower risk of death
Older adults who expend more energy through any daily activity, including non-exercise activity, have a lower rate of death than adults who are less active. view more (2006-07-12)
