Controlling algal blooms
Diatoms, highly successful photosynthetic plankton responsible for 40% of the net primary production in the oceans, undergo seasonal population explosions called phytoplankton blooms that attract billions of krill, copepods, and other grazing predators. view more (2006-02-21)
Cholera vaccine could protect affected communities
A vaccine used to protect travelers from cholera, an infection characterized by diarrhea and severe dehydration, could also be used effectively among those living in cholera-prone (endemic) areas. view more (2007-11-27)
Quantum Evolution - The New Science of Life
A clue to understanding life is the realisation that its dynamics are different than those that rule the non-living. For inanimate objects, the dynamics we see are the product of the disordered motion of billions of particles; they are a kind of average dynamics. At the macroscopic level we see patterns and order, but at the molecular level there... view more... (2000-01-31)
Eutrophication affects diversity of algae
Eutrophication of the seas may have an impact on genetic variation in algae, research at the University of Gothenburg shows. view more (2009-10-20)
Scientists from Scotland to Sweden Arrive at NIMBioS to Study Bovine TB
In 2008, the U.S. Department of Agriculture spent $31 million to depopulate herds of cattle affected by bovine tuberculosis (TB), even though the risk of the disease has been significantly reduced in the U.S. over the past several decades. view more (2009-07-13)
Study finds cancer is the second most frequent cause of death in individuals with schizophrenia
People with schizophrenia die from cancer four times as often as people in the general population. view more (2009-06-22)
Screening for colorectal cancer should start at age 50
New estimates of the lifetime risk of developing colorectal cancer, published in the Journal of Medical Screening, suggest that screening should start at age 50 or 55 in the general population. For individuals with a family history of colorectal cancer, screening is recommended from age 40-44. Using cancer registry data, researchers in France... view more... (2000-11-20)
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)
Polluted prey causes wild birds to change their tune
Considerable attention has been paid to the effects of endocrine disrupting chemicals in aquatic environments, but rather less attention has been given to routes of contamination on land. view more (2008-02-27)
Harvard scientists predict the future of the past tense
Verbs evolve and homogenize at a rate inversely proportional to their prevalence in the English language, according to a formula developed by Harvard University mathematicians who've invoked evolutionary principles to study our language over the past 1,200 years, from "Beowulf" to "Canterbury Tales" to "Harry Potter." view more (2007-10-11)
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)
WHEN BIKES BEHAVE LIKE SHIPS AT SEA
The precise conditions which generate these instabilities are not properly understood, but anecdotal evidence suggests that they are triggered by an uncommon combination of road profiling, road surface conditions and motorcycle loading, while the machine is executing a cornering manoeuvre. view more (1999-11-30)
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)
Evolution can occur in less than 10 years
How fast can evolution take place? In just a few years, according to a new study on guppies led by UC Riverside's Swanne Gordon, a graduate student in biology. view more (2009-06-11)
Which is more accurate, serology test or C14-urea breath test?
Serology and C14-UBT are the most commonly used non-invasive tests of H. pylori infection. The diagnostic characteristics of the tests depend also on the prevalence of H. pylori infection in the population tested. view more (2008-09-10)
FLUCTUATIONS IN BIOLOGICAL PRODUCTION IN THE EQUATORIAL PACIFIC UNDERTHE EFFECT OF EL NINO
A region of the western equatorial Pacific, the Pacific warm pool, has exceptionally warm surface waters (an average 28.5°C) which have low salinity and are oligotrophic (nutrient-poor). At the Equator the Eastern edge of this pool comes into contact with cooler water (24°C on average) which is saline and nutrient rich (especially in... view more... (1999-05-11)
NASA snow data helps maintain nation's largest, oldest bison herd
Grainy photographs of America's Old West recall a time when large bison herds migrated across wide prairie lands, 30 million strong, with the changing seasons determining their path and destination. view more (2006-11-03)
Bulimia And Impulsive Behavior Are Associated In Adolescence.
A group of investigators of the University of Tampere, headed by R.Kaltiala-Heino have found a strong association between bulimia and impulsive behavior. In clinical samples, bulimia seems to be associated with various dyscontrol behaviours suggesting weakness in impulse control. Population studies of adolescents, however, are needed. We evaluated... view more... (2003-01-13)
Which came first, the moth or the cactus?
It's not a good idea to put all your eggs in one basket- unless you're a senita moth. view more (2007-08-15)
Stroke victims at twice the risk of suicide
Stroke victims are at twice the risk of suicide, finds a study in the Journal of Epidemiology and Community Health. The increased risk remains for around five years after the stroke. view more (2001-11-09)
