'Thirst for knowledge' may be opium craving
Neuroscientists have proposed a simple explanation for the pleasure of grasping a new concept: The brain is getting its fix. view more (2006-06-21)
Obesity genetics
New evidence that genetics plays a key role in obesity is published today in the International Journal of Bioinformatics Research and Applications. The findings relate to the genetics of modern Pima Indians who have an unusually high rate of obesity but could be extrapolated to all people. view more (2007-10-16)
Apes - not monkeys - ace IQ tests
The great apes are the smartest of all nonhuman primates, with orangutans and chimpanzees consistently besting monkeys and lemurs on a variety of intelligence tests. view more (2006-08-02)
Old mystery solved, revealing origin of regulatory T cells that 'police' and protect the body
More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years. view more (2005-10-13)
Scientific design of GM farm-scale evaluations made public
The 40th anniversary issue of the British Ecology Society's Journal of Applied Ecology this month leads with two major papers describing the background, methodology and experimental design of the farm-scale evaluations of genetically modified herbicide-tolerant crops. In laying out the statistical design and methods of data collection for the... view more... (2003-02-07)
A vision to establish the UK as a global leader in oceanography
A vision for the future of Southampton Oceanography Centre (SOC) is revealed today by the Director designate, Professor Edward Hill. view more (2004-12-17)
Deakin University has developed a prototype tasty snack food with special health benefits
Dr Russell Keast, a senior lecturer in the school of exercise and nutrition sciences, has developed a new snack food with a parmesan cheese cracker, organic mashed potato and special healthy additives. view more (2006-06-27)
U of MN researchers use human embryonic stem cells to kill cancer cells
For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors). view more (2005-10-12)
Damage to sperm DNA affects older men's chances of fathering children
Damage to DNA in sperm is significantly higher in older men than in those who are younger, according to research presented today (Tuesday 21 June 2005) at the 21st annual conference of the European Society of Human Reproduction and Embryology. view more (2005-06-21)
Haplotype map offers new insights into human disease, evolution
In several papers published this week in Nature, Nature Genetics, PLoS Biology and Genome Research, Broad researchers and an international set of collaborators announce substantial advances in relating human genetic variation to disease and understanding human evolutionary history. view more (2005-10-27)
Working memory retains visual details despite distractions
The ability to retain memory about the details of a natural scene is unaffected by the distraction of another activity and this information is retained in "working memory". view more (2006-01-20)
Natural selection has strongly influenced recent human evolution, Cornell/Celera Genomics study finds
he most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species. view more (2005-10-24)
Species evolve to the brink of evolution
A biologist at The University of Texas at Austin has presented a new theory that sheds light on how organisms, including viruses like HIV, rapidly evolve in the face of vaccines and antibiotics. view more (2005-08-29)
Fish evolve a longer lifespan by evolving a longer reproductive period, researchers find
A UC Riverside-led research team has found that as some populations of an organism evolve a longer lifespan, they do so by increasing only that segment of the lifespan that contributes to "fitness" - the relative ability of an individual to contribute offspring to the next generation. view more (2005-12-27)
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 population growth are rarely perfect, but are... view more... (2003-12-10)
Why some people are more attractive than others
Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different? view more (2007-03-28)
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)
New 'implanted contacts' designed to fix nearsightedness
UT Southwestern Medical Center ophthalmologists will be the first in the area to insert a new type of implanted lens to fix nearsightedness. view more (2006-02-28)
How butterflies got their spots: A 'supergene' controls wing pattern diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive-some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid. view more (2006-09-26)
DNA size a crucial factor in genetic mutations, study finds
Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA. view more (2005-10-27)
