Lineage trees for cells
Some fundamental outstanding questions in science - "Where do stem cells originate?" "How does cancer develop?" "When do cell types split off from each other in the embryo?" - might be answered if scientists had a way to map the history of the body's cells going back... view more (2005-10-31)

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... view more (2004-07-30)

No need to thank dinosaur-killing asteroid for mammalian success
It is a natural history tale that every third grader knows: The dinosaurs ruled the Earth for hundreds of millions of years, until an asteroid struck the Yucatan Peninsula and triggered a mass extinction that allowed the ancestors of today's mammals to thrive.   view more (2007-03-29)

Researchers put gingko on trial for treatment of dementia
Researchers in London are to explore the effectiveness of gingko, a complementary medicine traditionally used to treat circulatory problems, as a treatment for early dementia. The study of 250 patients aged over 55 will seek to find out whether GPs can help patients by prescribing the supplement to... view more (2004-08-19)

Colorado River streamflow history reveals megadrought before 1490
An epic drought during the mid-1100s dwarfs any drought previously documented for a region that includes areas of Arizona, Colorado, New Mexico, Utah and Wyoming.   view more (2007-05-18)

Transgene Aspen And Cloned Karelian Birch
Long ago genetic engineering got deep reach into pharmacological and food industry, agriculture and medicine. The trees are no exclusion, but genetic engineers started to deal with them approximately ten years later than with other objects: the trees are too difficult for genetic investigations and... view more (2003-06-16)

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... view more (2000-06-09)

Growth hormone is made in the brain, report scientists
Scientists have found that growth hormone, a substance that is used for body growth, is produced in the brain, according to an article published in this week's Proceedings of the National Academy of Sciences.   view more (2006-03-28)

Winning by a neck — Giraffes avoid competing with shorter browsers
The giraffe's elongated neck has long been used in textbooks as an illustration of evolution by natural selection, but this common example has received very little experimental attention.   view more (2006-12-26)

Scientists discover a genetic switch that links animal growth and cancer
Laboratory discoveries by scientists at two universities may lead to new directions in cancer therapy drugs.   view more (2006-04-18)

Hormone therapy helps short children grow up
Growth hormone treatment may significantly increase final height in children diagnosed with short stature, even in cases where the child is not growth hormone deficient, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism... view more (2008-11-06)

NEW TEST FOR DOPING IN RACEHORSES
Scientists from Britain, Australia and South Africa have collaborated to develop a new test for drug abuse in racehorses. Use of growth hormone doping is worrying both horse racing and athletics authorities. Now new work, presented at the British Endocrine Societies annual meeting in Birmingham,... view more (2000-03-07)

Growth hormone's link to starvation may be clue to increasing life span, researchers find
Researchers at UT Southwestern Medical Center have determined that starvation blocks the effects of growth hormone via a mechanism that may have implications in treating diabetes and extending life span.   view more (2008-06-30)

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... view more (2003-12-10)

Historic Colorado River streamflows reconstructed back to 1490
A new tree-ring-based reconstruction of 508 years of Colorado River streamflow confirms that droughts more severe than the 2000-2004 drought occurred before stream gages were installed on the river.   view more (2006-05-26)

Fungal factories may save hemlock forests
Reaching into a box glowing with fluorescent light, Stacie Grassano pulls out a tube. "This is a great one," she says, holding the clear plastic up to her face. Inside, a tree branch is speckled with white fluff. "It's growing really well," she says, handing it to Scott Costa.   view more (2007-01-29)

First functional insulin-binding protein in invertebrates
Insulin-like growth factor (IGF) signaling that helps to regulate mammals' growth, metabolism, reproduction and longevity is well documented.   view more (2008-04-15)

New family of gecko discovered by researchers from the U of Minnesota and Villanova University
Researchers at the University of Minnesota's Bell Museum of Natural History and Pennsylvania's Villanova University have discovered a new family of gecko, the charismatic large-eyed lizard popularized by car insurance commercials.   view more (2008-05-23)

Firewood unintentionally transports emerald ash borer
What could be more harmless than a bundle of firewood? Depending on where it came from, it could be a Trojan horse for emerald ash borers.   view more (2007-02-01)

Causes of rubber tree bark necrosis identified
The rubber tree, Hevea brasiliensis, is cultivated in many humid tropical countries for the latex it produces, from which is extracted natural rubber mainly used by the tyre industry. Asia alone provides almost 95 % of the world production, where the first producer is Thailand whose rubber industry... view more (2005-04-15)

Dual-drug therapy targets one colon cancer gene
Johns Hopkins Kimmel Cancer Center scientists have found that interferon, used for 30 years to treat blood cancers, multiple sclerosis and hepatitis, selectively kills colon cancer cells when combined with another standard chemotherapy agent.   view more (2005-08-18)

Growth hormone to boost athletic performance risks diabetes
Use of growth hormone to boost athletic performance can lead to diabetes, reports a study published ahead of print in the British Journal of Sports Medicine.   view more (2007-02-26)

Poplar DNA code cracked — new possibilities for sustainable energy
Sustainable or renewable energy - in the form of bio-ethanol, for example - can be produced for us by trees. The influence trees have on our daily life is enormous. Forests cover 30% of the world's land area, accommodate two thirds of life on earth, and are responsible for 90% of the biomass on... view more (2006-09-15)

Prostate cancer spurs new nerves
Prostate cancer - and perhaps other cancers - promotes the growth of new nerves and the branching axons that carry their messages, a finding associated with more aggressive tumors, said researchers from Baylor College of Medicine in the first report of the phenomenon that appears today in the... view more (2008-12-01)

Can poor growth explain link between marital status and health?
A recent study in the BMJ found that men who were small at birth were less likely to marry, but can slow growth also explain why unmarried people are more likely to die of heart disease?   view more (2002-02-13)
