Can hearing voices in your head be a good thing?
Psychologists have launched a study to find out why some people who hear voices in their head consider it a positive experience while others find it distressing. view more (2006-09-14)
Scientists use seismic waves to locate missing rock under Tibet
Geologists at the University of Illinois at Urbana-Champaign have located a huge chunk of Earth's lithosphere that went missing 15 million years ago. By finding the massive block of errant rock beneath Tibet, the researchers are helping solve a long-standing mystery, and clarifying how continents behave when they collide. view more (2007-02-08)
Disease-impact models may rely on incorrect assumptions
Even when we know how a disease affects individual animals, it is challenging to predict what impact it will have on the whole population, and yet predicting how disease affects a population is a primary concern for wildlife conservation and even public health. view more (2006-04-13)
Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness. In the February issue of Ecology Letters,... view more... (2003-01-28)
The future of tropical forests
Deforestation and habitat loss are expected to lead to an extinction crisis among tropical forest species. Humans in rural settings contribute most to deforestation of extant tropical forests. view more (2006-04-07)
Researchers build an ultrasound version of the laser
Researchers at the University of Illinois at Urbana-Champaign and at the University of Missouri at Rolla have built an ultrasound analogue of the laser. view more (2006-06-09)
Insect population growth likely accelerated by warmer climate
Insects have proven to be highly adaptable organisms, able through evolution to cope with a variety of environmental changes, including relatively recent changes in the world's climate. But like something out of a scary Halloween tale, new University of Washington research suggests insects' ability to adapt to warmer temperatures carries an... view more... (2006-10-31)
Man-Made Climate Change
A new study published in this week's issue of Nature is the first to show that human activity is altering the circulation of the tropical atmosphere and ocean through global warming. view more (2006-05-04)
Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on population growth are rarely perfect, but are... view more... (2003-12-10)
Preserved in crystal
Scientists at the Weizmann Institute of Science recently discovered a new source of well-preserved ancient DNA in fossil bones. view more (2006-02-03)
U of MN researchers identify new cord blood stem cell
Researchers at the University of Minnesota Medical School have discovered a new population of cells in human umbilical cord blood that have properties of primitive stem cells. view more (2006-02-14)
Cure for cancer worth $50 trillion
A new study, to be published in a forthcoming issue of the Journal of Political Economy, calculates the prospective gains that could be obtained from further progress against major diseases. view more (2006-04-27)
Research advances understanding of how hydrogen fuel is made
Oxygen may be necessary for life, but it sure gets in the way of making hydrogen fuel cheaply and abundantly from a family of enzymes present in many microorganisms. view more (2005-10-06)
Brighter future for giant panda?
Scientists at Cardiff University, using a novel method to estimate population, have found that there may be many more giant pandas remaining in the wild than previously thought. view more (2006-06-20)
Inside a quantum dot: Tracking electrons at trillionths of a second
Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. view more (2005-11-28)
Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust. view more (2005-08-08)
Scientists discuss evolutionary roots of social behavior
Researchers have long reflected on that most intriguing of evolutionary questions: what led to the emergence of social behavior? view more (2006-02-21)
Genetic study shows humans have pushed orangutans to the brink of extinction
A new study published in the open-access journal PLoS Biology shows strong genetic evidence of a catastrophic collapse in orangutan populations living in the fragmented forests of the Kinabatangan Wildlife Sanctuary in Sabah, Malaysia. view more (2006-01-24)
Astronomers shed surprising light on our galaxy's black hole
In the most comprehensive study of Sagittarius A (Sgr A), the enigmatic supermassive black hole in the center of the Milky Way Galaxy, astronomers - using nine ground and space-based telescopes including the Hubble Space Telescope and the XMM-Newton X-ray Observatory - have discovered that Sgr A* produces rapid flares close to the... view more...

MIT researcher sees big impact of little cracks
An MIT researcher's atom-by-atom simulation of cracks forming and spreading may help explain how materials fail in nanoscale devices, airplanes and even in the Earth itself during a quake. view more (2006-01-19)
