Human activities are boosting ocean temperatures in areas where hurricanes form, new study finds
Rising ocean temperatures in key hurricane breeding grounds of the Atlantic and Pacific oceans are due primarily to human-caused increases in greenhouse gas concentrations. view more (2006-09-12)
Scientists warn of climate change risk to marine turtles
North American marine turtles are at risk if global warming occurs at predicted levels, according to scientists from the University of Exeter. An increase in temperatures of just one degree Celsius could completely eliminate the birth of male turtles from some beaches. view more (2007-02-20)
UC Riverside researchers release new variety of asparagus
UC Riverside researchers have released a new variety of asparagus that offers a higher yield than previous varieties of the vegetable and boasts an excellent spear quality, marked by a high percentage of marketable spears. view more (2006-02-15)
How to Grow a Bigger Brain
Hatchery-reared steelhead trout show increased growth of some parts of the brain when small stones are scattered on the bottom of their tank, according to a new study by researchers at UC Davis. view more (2006-03-07)
Penguins marching into trouble
A quarter-century of data reveals how changing weather patterns and land use, combined with overfishing and pollution, are taking a heavy toll on penguin numbers view more (2009-02-13)
Males with elevated levels of testosterone lead shorter lives but have more success siring offspring
Comparative studies have studied testosterone levels and related them to mating systems and aggression, but very few studies have attempted to relate testosterone to fitness, that is, the combination of lifetime reproductive success and survival, in the wild or experimentally. view more (2006-04-13)
Found — the apple gene for red
CSIRO researchers have located the gene that controls the colour of apples - a discovery that may lead to bright new apple varieties. view more (2006-12-04)
Northern birds are fatter!
"The further birds migrate north for the summer, the faster they put on weight", says Dr Williams (Simon Fraser University, Canada) who has been tracking migrating birds for several years. view more (2006-04-04)
Building disease-beating wheat
Disease resistance genes from three different grass species have been combined in the world's first 'trigenomic' chromosome, which can now be used to breed disease resistant wheat varieties. view more (2007-12-13)
Sexual reproduction delays aging in a mammalian species
Past research on aging and the life histories of diverse species has shown that sexual reproduction is biologically costly for individuals and tends to decrease lifespan rather than increase it. view more (2006-02-22)
Proteins are key to cell death in heart disease, stroke and degenerative conditions
Researchers at Yale School of Medicine have gained deeper understanding of two members of a family of proteins called caspases that play a key role in promoting apoptosis, a process in which the cell responds to external signals by essentially committing suicide. view more (2006-02-23)
Conflict over rearing young shapes breeding systems
An article in the October 2006 issue of BioScience, the monthly journal of the American Institute of Biological Sciences (AIBS), describes evidence that conflict between male and female shorebirds over which member of a breeding pair will raise their young has had a profound influence on the evolution of breeding systems in these birds. view more (2006-10-03)
Race to halt global amphibian crisis boosted by rediscovery of endangered Colombian frogs
The rediscovery of two frog species feared extinct has made a new Colombian protected area the focal point for efforts to save amphibians from a deadly fungus decimating their populations in Central and South America. view more (2006-06-07)
Sharks in danger
There are 370 species of shark, each with their own particular habitats and behaviours. Most sharks are slow to reproduce and do not have large numbers of young. They are therefore particularly sensitive to predation or large losses. Caught as accidental by-catch (estimated at 3000 per day), sharks are also fished for their fins (for food),... view more...

Experts develop global action plan to save amphibians facing extinction
A summit of leading scientists have agreed to an action plan intended to save hundreds of frogs, salamanders and other amphibians facing extinction from familiar threats such as pollution and habitat destruction, as well as a little-known fungus wiping out their populations. view more (2005-09-21)
Duke study examines evolutionary consequences of bluebird aggression
In findings that may offer insight into how evolution operates, a Duke University evolutionary ecologist reported evidence that aggressive male western bluebirds out-compete less aggressive males for preferred breeding territories. view more (2006-04-13)
Ray of hope for vultures facing extinction
Today saw a glimmer of hope for the three species of Asian vulture threatened with extinction. view more (2006-01-31)
Important gene controlling tree growth and development found
Scientists at the UmeĆå Plant Science Centre (UPSC) and the Swedish University of Agricultural Sciences (SLU) report today about a breakthrough in our understanding of how the growth and development of forest trees is controlled. view more (2006-05-05)
Dog genome sequence and analysis published in Nature
An international research team led by scientists at the Broad Institute of MIT and Harvard announced today the completion of a high-quality genome sequence of the domestic dog, together with a catalog of 2.5 million specific genetic differences across several dog breeds. view more (2005-12-08)
Ancient genes used to produce salt-tolerant wheat
Two recently discovered genes from an ancient wheat variety have led to a major advance in breeding new salt-tolerant varieties. view more (2007-02-05)
