Discovered: World's Largest Tsunami Debris
A line of massive boulders on the western shore of Tonga may be evidence of the most powerful volcano-triggered tsunami found to date. Up to 9 meters (30 feet) high and weighing up to 1.6 million kilograms (3.5 million pounds), the seven coral boulders are located 100 to 400 meters (300 to 1,300 feet) from the coast. view more (2008-09-26)
Study of coastal disasters yields surprising findings, arresting images
Two of the world's worst natural disasters in recent years stemmed from different causes on opposite sides of the globe, but actually had much in common, according to researchers who are part of a large National Science Foundation-funded research initiative that has been studying both the Indian Ocean Tsunami of 2004 and the Hurricane Katrina of... view more...

Robot-assisted, laparoscopic surgery for vaginal vault prolapse found to be effective
Mayo Clinic researchers have found that laparoscopic surgery assisted by a surgical robot to fix vaginal vault prolapse, a collapse of the vagina that can occur after a hysterectomy, is an effective option to the traditional, open surgical repair when measured at least a year after the surgery. view more (2006-07-24)

Insomniac flies resemble sleep-deprived humans
Researchers at Washington University School of Medicine in St. Louis have created a line of fruit flies that may someday help shed light on the mechanisms that cause insomnia in humans. view more (2009-06-03)
Predators drive the lemming cycle in Greenland
A recent study conducted in eastern Greenland and published in the October 31 issue of the Science magazine provides new understanding of the dynamics of arctic lemming populations. Olivier Gilg and Ilkka Hanski from the University of Helsinki, Finland, and Beno'®t Sittler from the University of Freiburg, Germany, combined long-term field... view more... (2003-10-29)
GEN reports on expanding NextGen sequencing applications
Next-Generation Sequencing (NGS) technologies are not only beginning to supplant traditional Sanger sequencing methodology but are also giving DNA microarrays a run for the money as well, reports Genetic Engineering & Biotechnology News (GEN). view more (2009-09-04)
Gannet population under threat from global warming
Researchers at the University of Leeds have warned that global warming is a major threat to the gannet, a species known for its stable populations and constant breeding success. view more (2007-06-19)
One in four patients has been drinking before arrival at accident and emergency
One in four patients has been drinking before arrival at accident and emergency, reveals a study in Emergency Medicine Journal. Alcohol was implicated in almost all cases of self-harm, almost half of collapses, half of all assaults, and half of admissions to hospital, the findings show. A survey was carried out of all new attenders aged 10 and... view more... (2001-06-29)
Stressed cells spark DNA repair missteps and speed evolution
When Dr. Susan Rosenberg, professor of molecular and human genetics at Baylor College of Medicine, first published her finding that the mutation rate increased in bacteria stressed by starvation, sometimes resulting in a rare change that benefited the bacteria, it was controversial. view more (2005-09-16)
Accelerating loss of ocean species threatens human well-being
An international group of ecologists and economists has shown that the loss of biodiversity is profoundly reducing the ocean's ability to produce seafood, resist diseases, filter pollutants and rebound from stresses such as overfishing and climate change. view more (2006-11-07)

Superglue from the sea
Sandcastle worms live in intertidal surf, building sturdy tube-shaped homes from bits of sand and shell and their own natural glue. view more (2008-11-25)
Turn back, wayward axon
To a growing axon, the protein RGMa is a "Wrong Way" sign, alerting it to head in another direction. As Hata et al. demonstrate in the March 9, 2009 issue of the Journal of Cell Biology, translating that signal into cellular action requires teamwork from two receptors. view more (2009-03-09)
Crustacean shell with polyester creates mixed-fiber material for nerve repair
In the clothing industry it's common to mix natural and synthetic fibers. Take cotton and add polyester to make clothing that's soft, breathable and wrinkle free. view more (2009-06-17)
Equations against hypothermia
Sharks are, by tradition, the eternal threat facing divers. Yet, a diver is quite a lot more unlikely to meet such a creature under the water than, at some time or another, to come up against an even greater danger - hypothermia, or exposure. To enable divers to prevent this syndrome from creeping silently up on them, two researchers from the Area... view more... (2004-09-01)
Death by hyperdisease
It took less than a decade for native rats to become extinct on the Indian Ocean's previously uninhabited Christmas Island once Eurasian black rats jumped ship onto the island at the turn of the 20th century. view more (2008-11-05)
Budget research credit for private sector welcome - Public sector research must benefit from the Spending Review
Save British Science today welcomed the Chancellor of the Exchequer`s £400 million package of tax credits for companies carrying out research and development. "We knew this credit was coming, because there has been extensive consultation, but now we know the rate," said Dr Peter Cotgreave, Director of SBS. "Some people may complain that this... view more... (2002-04-17)
Students blow up the universe for Morse creator Colin Dexter
School students will blow up the universe, smash spinning eggs together, and make cola cans implode to try and win one of the UK's most challenging science competitions, to be held in London on Wednesday 31st March. Paperclip Physics is organised by the Institute of Physics and the students taking part will have to explain some of the most complex... view more... (2004-03-30)
New Tools Developed for Studying Neurodegenerative Brain Disorders
Penn State researchers have created an elegantly simple model of an axon-the extension of a neuron that communicates with other neurons-and have used this model to reproduce a change in the axon's shape that is characteristic of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. view more (2006-03-22)
