Intensive training may not be as bad for young women as previously thought
Intensive training may not stunt young women's physical development as we have been led to believe. Writing in the British Journal of Sports Medicine, Professor Nicolo Maffulli of Keele University and Dr Adam Baxter-Jones of the University of Saskatchewan, Canada, contend that this widely held view is not supported by the available evidence. view more (2002-02-01)
Study finds human population expanded during late Stone Age
Genetic evidence is revealing that human populations began to expand in size in Africa during the Late Stone Age approximately 40,000 years ago. view more (2009-07-29)
Predicting growth hormone treatment success
Growth hormone treatments work better on some children than on others, but judging which candidates will gain those vital inches in height is no simple task. view more (2007-12-13)
Climate change following collapse of the Maya empire
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease in the population following the collapse of the... view more... (2002-01-29)
Growth factor stimulates rapid extension of key motor neurons in brain
A growth factor known to be important for the survival of many types of cells stimulates rapid extension of corticospinal motor neurons - critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease). view more (2006-11-06)
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)
Einstein researchers identify potential target for metastatic cancer
The deadliest part of the cancer process, metastasis, appears to rely on help from macrophages, potent immune system cells that usually defend vigorously against disease, researchers at Albert Einstein College of Medicine of Yeshiva University report. view more (2009-08-11)
Risk threshold of daily alcohol intake and drinking duration in liver injury?
Alcoholic threshold effect rather than a dose-response effect on mortality from alcohol-related liver injury. Alcohol intake, rather than the type of alcoholic beverage, was more significant to liver injury. view more (2008-05-21)
Population growth puts dent in natural resources
It's a 500-pound gorilla that Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, sees standing on the speaker's dais at political rallies, debates and campaigns. Its name is population growth. view more (2008-10-08)
Researchers Turning Freshwater Farm Ponds into Crab Farms
Work by researchers at North Carolina State University is leading to a new kind of crab harvest - blue crabs grown and harvested from freshwater ponds, instead of from the sea. view more (2008-10-10)
Edge density key to controlling gypsy moth spread
Controlling population peaks on the edges of the gypsy moth range may help to slow their invasion into virgin territory, according to a team of researchers. view more (2006-11-16)
Greenhouse Gases - Nothing To Blame For?
In the nearest future we may witness global cooling in spite of increasing concentration of greenhouse gases in the atmosphere. That can happen, if the following hypothesis is correct: not the growth of greenhouse gases concentration provokes temperature to rise, but vice versa. It is generally believed nowadays that greenhouse gases are... view more... (2004-07-30)
HIV's impact in Zimbabwe explored in new research
The impact of HIV in Zimbabwe since the early 1980s is explored in new research published this week in the journal PNAS. view more (2007-08-28)
Twins have lower risk of suicide than general population
Twins have a lower risk of suicide compared with the general population, concludes a study in this week’s BMJ. view more (2003-08-12)
Commercial fishing causes dangerous fluctuations in fish populations
Commercial fishing causes serious fluctuations in fish populations leaving them in danger of total collapse, says new research published today. view more (2006-10-19)
DNA research flies high with Seychelles kestrel
A new research project at the University of Kent is looking for genetic evidence of a historical population bottleneck in the Seychelles kestrel by analysing DNA extracted from museum specimens estimated to be 100-150 years old. Dr Jim Groombridge, Lecturer in Biodiversity Conservation at the University's Durrell Institute of Conservation and... view more... (2004-06-01)
May supplementation of docosahexaenoic acid suppress colon tumor cell growth?
Colon cancer is one of the leading causes of death in Western countries. The role of n-3 and n-6 PUFAs in colorectal carcinoma cell growth has not been well studied. It is known that PGE2, generated from AA, is an important factor in the tumorigenesis of colorectal cancer. view more (2009-03-09)
Behind The Growth Of Alternative Medicine: Unmet Psychosmatic Needs Of Medical Practice
The past decade has witnessed an impressive growth of alternative medicine. The Authors of this review suggest that key psychosmatic concepts (a holistic consideration of patient care; the role of psychosocial factors in affecting individual vulnerability to all types of disease; the interaction between psychosocial and biological factors in the... view more...

Cardiac stent patients with diabetes may benefit from drug that counteracts the effects of leptin
The naturally high levels of leptin in diabetic patients may reduce the effectiveness of drug-eluting stents used to treat heart blockages, but using a chemical that differs from the one commonly used to coat stents could counteract this effect. view more (2008-12-18)
