New population of Iberian lynx raises hope, says World Wildlife Fund
Spanish authorities have announced they have discovered a previously unknown population of Iberian lynx, triggering hope for one of the world's most endangered cat species, said World Wildlife Fund today. view more (2007-10-24)
Adult brain neurons can remodel connections
Overturning a century of prevailing thought, scientists are finding that neurons in the adult brain can remodel their connections. view more (2008-11-25)
Water, air and soil pollution causes 40 percent of deaths worldwide, Cornell research survey finds
About 40 percent of deaths worldwide are caused by water, air and soil pollution, concludes a Cornell researcher. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases, which the World Health Organization has recently reported. view more (2007-08-14)
Increased suicide risk from low birthweight babies and those born to teenage mothers (pp 1102, 1135)
Results of a prospective population study from Sweden in this week's issue of THE LANCET highlight how low birthweight and being born to a teenage mother are independent risk factors associated with increased risk of suicide in later life. The study also shows how being born fourth or more in sibling order and poor maternal socio-economic status... view more... (2004-09-22)
Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust. view more (2005-08-08)
Global trade in tiger shrimp threatens environment
The cultivation of shrimp and fish in tropical coastal areas is often described as an environmentally friendly way to alleviate poverty, but in fact this cultivation has negative consequences for both the local population and the environment. Daniel A. Bergquist of Uppsala University, Sweden, has studied how policies for sustainable development... view more... (2008-02-15)
Fly population set to double with global warming
A leading biological scientist from the University of Southampton is warning of massive increases in the UK's fly population if temperatures continue to rise. view more (2004-09-27)
Harvard scientists identify compounds that stimulate stem cell growth in the brain
cientists at Harvard University have identified key compounds that stimulate stem cell growth in the brain, which may one day lead to restored function for people affected by Parkinson's disease, strokes, multiple sclerosis, and a wide range of neurological disorders. view more (2006-09-01)
Scientists find potential protein biomarkers for growth hormone
Ohio University scientists have identified several proteins in mice that might act as biomarkers for growth hormone. The research could be the first step to finding a more reliable way to detect recombinant human growth hormone (rhGH), which some athletes and teenagers use illegally to boost muscle and reduce fat. view more (2008-06-18)
The 'green revolution gene' goes to the root of how plants control their growth.
Scientists at the John Innes Centre (JIC) Norwich(1), have discovered how plants coordinate and control their development by using a master signal to regulate the growth of cells throughout the plant. The signal, a plant hormone called auxin, affects the ability of cells to respond to another hormone (gibberellin(2)) that 'switches on' cell... view more... (2003-02-11)
How does one sex grow larger than the other?
Why are males larger than females in some animal species (such as most mammals), females larger than males in others (such as most insects), and why are the sexes alike in yet other species (such as several birds)? view more (2007-01-30)
Herbal alternative to farmyard antibiotics
Research at the University of Leeds into herbal remedies in the farmyard could soon see pigswill garnished with garlic and cows chewing on cinnamon-flavoured cud. With an EU ban on antibiotic growth promoters in animal feed from 2006, alternatives need to be found urgently. The use of plant extracts, once dismissed as quack science, is attracting... view more... (2004-01-26)
Carnivore extinction risk determined more by biology than human population density, says study
Carnivores around the world are more at risk of extinction due to their own intrinsic biological attributes than from an increasing human population with whom they share their space, say scientists in a study published this week. Researchers looking at all 280 carnivore species around the world estimated the risk of their extinction by 2030 based... view more... (2004-07-15)
Assessing levies for accidental by-catch, say researchers, could generate money to protect threatened species
Fishing industry lines accidentally catch so many seabirds and turtles that their populations are being threatened. One solution offered by a Cornell researcher and an Australian government scientist is to assess fines when threatened species are caught and killed. view more (2007-07-19)
Catching waves: Measuring self-assembly in action
By making careful observations of the growth of a layer of molecules as they gradually cover the surface of a small silicon rectangle, researchers from the National Institute of Standards and Technology (NIST) and North Carolina State University (NCSU) have gained basic insights into how self-propagating self-assembly wave fronts develop and have... view more...

Anti-fungal drug stops blood vessel growth
Researchers at Johns Hopkins have discovered to their surprise that a drug commonly used to treat toenail fungus can also block angiogenesis, the growth of new blood vessels commonly seen in cancers. view more (2007-04-30)
Novel model of osteosarcoma
In the June 15th issue of G&D, Dr. Stuart Orkin (HHMI, Dana-Farber Cancer Institute, Children's Hospital Boston) and colleagues present a new mouse model of osteosarcoma. view more (2008-06-16)
The bonsai effect: Wounded plants make jasmonates, inhibiting cell division, stunting growth
It is well known that plants growing under unfavourable conditions are generally smaller than those growing in stress-free conditions: indeed it is estimated that in the US, abiotic stress reduces the yield of agricultural crops by an average of 22%. view more (2008-11-12)
New research may explain why some who receive growth hormone therapy develop colon polyps
The use of growth hormone therapy has been linked in some people to the development of colon polyps, a possible precursor to colorectal cancer - but medical researchers have debated the extent of a cancer risk. view more (2006-04-10)
Exercise boosts sex hormone in older men
Older men who take regular and intensive exercise produce more growth hormone and testosterone, the male sex hormone, than those who lead an inactive life, according to researchers at the University of Newcastle-upon-Tyne. Men aged 55-65 who ran more than 40 miles a week were found to have higher levels of both hormones in their bodies compared to... view more... (2000-05-30)
