Sequence matters in droughts and floods
When extremes of drought and flood come in rapid succession, the extent of damage to vegetation may depend in part on the sequence of those events, according to a new study published in The American Naturalist. view more (2009-01-08)
Emerging model organisms featured in CSH Protocols
Biological research has long relied on a small number of model organisms, species chosen because they are amenable to laboratory research and suitable for the study of a range of biological problems. view more (2008-10-02)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Better Smaller, But More
In the city, frogs do not feel as comfortable as in the wild nature because of dirty water, a lack of food, and dangers at every turn. That is why the life of frogs in urban areas is shorter. However, they do not leave these habitats, but adapt to them. Apparently, there are two ways to adapt: either become more tolerant or increase the number of... view more... (2002-04-12)
New findings contradict a prevailing belief about the inner ear
A healthy ear emits soft sounds in response to the sounds that travel in. Detectable with sensitive microphones, these otoacoustic emissions help doctors test newborns' hearing. A deaf ear doesn't produce these echoes. view more (2008-02-13)
Sea mollusks taste their memories to build shells
University of California, Berkeley, graduate student Alistair Boettiger has amassed a beautiful collection of seashells, but not by combing the beach. He created them in his computer. view more (2009-04-02)
NASA's robotic sub readies for dive into Earth's deepest sinkhole
An underwater robot, shaped like a flattened orange, maneuvered untethered and autonomously within a 115-meter-deep sinkhole during tests this month in Mexico, a prelude to its mission to probe the mysterious nether reaches of the world's deepest sinkhole. view more (2007-03-01)
Study rules out inbreeding as cause of amphibian deformities
Although research has linked inbreeding with elevated rates of deformity in a wide variety of animals, a new study finds it plays no part in the high incidence of malformation among salamanders. view more (2008-10-29)
Scientists find solution to solar puzzle
Scientists from the University of Sheffield and Queen's University Belfast have made a unique discovery which will help us understand one of the most puzzling features of the Sun. view more (2009-03-23)
Beavers helping frogs, toads survive
The humble beaver, besides claiming a spot of honour on the Canadian nickel, is also helping fellow species survive. view more (2007-01-12)
MTBE contamination: A microbial approach for groundwater
Max Häggblom's Rutgers laboratory has taken an important step on the path to using microbes to rid the environment of methyl tertiary-butyl ether (MTBE), a toxic gasoline additive now classified as a potential human carcinogen. view more (2006-03-22)
Case Western Reserve professor helps control infectious diseases with models and math
Can an algebraic equation hold the secret to eradicating malaria or schistosomiasis? A Case Western Reserve University mathematics professor is utilizing the combination of algorithms and models in an effort to assist his medical colleagues in the fight against infectious diseases. view more (2008-12-22)
Disorder enables extreme sensitivity in piezoelectric materials
A research team working at the National Institute of Standards and Technology (NIST) has found an explanation for the extreme sensitivity to mechanical pressure or voltage of a special class of solid materials called relaxors. view more (2008-05-19)
Has SOHO ended a 30-year quest for solar ripples?
The ESA-NASA Solar and Heliospheric Observatory (SOHO) may have glimpsed long-sought oscillations on the Sun's surface. The data will reveal details about the very core of our central star and it contains clues as to how the Sun formed, 4.6 billion years ago. view more (2007-05-04)
Remote island provides clues on population growth, environmental degradation
Halfway between South America and New Zealand, in the remote South Pacific, is Rapa. This horseshoe-shaped, 13.5 square-mile island of volcanic origin, located essentially in the middle of nowhere, is "a microcosm of the world's situation," says a University of Oregon archaeologist. view more (2006-08-28)
Now hear this
Deep in the ear, 95 percent of the cells that shuttle sound to the brain are big, boisterous neurons that, to date, have explained most of what scientists know about how hearing works. view more (2009-10-23)
Toxic chemicals affect steroid hormones differently in humans and invertebrates
In a study with important consequences for studies on the effects of chemicals on steroid responses in humans, a team of French and American scientists, including Michael E. Baker, PhD, professor in UC San Diego's Department of Medicine, Division of Nephrology-Hypertension, have found that - contrary to earlier assumptions - enzymes used for the... view more...

The precautionary behaviour of Octopus vulgaris: the biology of common octopus populations off North-West Africa
Having appeared abruptly in abundance off the Senegalese coasts in 1986, the common octopus, Octopus vulgaris, today represents the main income of 6-7000 traditional fishing concerns in Senegal. In 1998, nearly 2500 tonnes were landed generating a turnover of 3000 million CFA (French African Community) francs. So important is this fishing resource... view more... (2000-05-22)
Researchers reveal mystery of bacterial magnetism
Scientists at the Naval Research Laboratory (NRL) and Purdue University have shed light on one of microbiology's most fascinating mysteries-why some bacteria are naturally magnetic. view more (2006-10-23)
Nanotechnology may increase longevity of dental fillings
Tooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. view more (2009-07-02)
