As concerns about the effects of global warming continue to mount, a new study published in the December issue of Physiological and Biochemical Zoology finds that an increase in average temperature of only two degrees Celsius could have a devastating effect on populations of Australia's iconic kangaroos. view more (2008-10-16)
More Evidence Chicxulub Was Too Early
A new study of melted rock ejected far from the Yucatan's Chicxulub impact crater bolsters the idea that the famed impact was too early to have caused the mass extinction that killed the dinosaurs 65 million years ago. view more (2006-03-30)
A world ruled by fungi
The catastrophe that extinguished the dinosaurs and other animal species, 65 million years ago also brought dramatic changes to the vegetation. In a study presented in latest issue of the journal Science, the paleontologists Vivi Vajda from the University of Lund, Sweden and Stephen McLoughlin from the Queensland University of Technology,... view more...

New window into ancient ozone holes
British researchers have hit on a clever way to search for ancient ozone holes and their relationship to mass extinctions: measure the remains of ultraviolet-B absorbing pigments ancient plants left in their fossilized spores and pollen. view more (2005-08-10)
Glucose levels trigger compensation for type 2 diabetics
Many individuals with type 2 diabetes are diabetic because the cells of their body no longer respond to the hormone insulin, which is crucial for lowering blood sugar levels (blood glucose levels). view more (2007-01-03)

Obesity associated with higher risk for urinary tract infections
As body mass increases, so does a patient's risk of urinary tract infection (UTI), according to Baltimore researchers. A new study, presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA) assesses and stratifies this risk. view more (2009-04-27)

Lean muscle-mass may give even obese people an advantage in battling cancer, a University of Alberta study shows. view more (2008-12-18)
Wobbly Toddlers
The immature co-ordination of first-time walkers makes balance difficult. To overcome this problem toddlers adopt a more stable pattern of walking. A pilot study presented at the Society for Experimental Biology conference in Swansea today has recorded this pattern of locomotion which may help in the understanding and treatment of walking... view more...

Research shows women's weight gain brings loss of income, job prestige
An increase in a woman's body mass results in a decrease in her family income and a decline in her occupational prestige, according to research conducted by New York University sociologist Dalton Conley and Rebecca Glauber, an NYU graduate student. The study was sponsored by the Cambridge, MA-based National Bureau of Economic Research. view more (2005-05-26)
New standard mass made with ISTC help
This program began three years ago and it involves scientists from eight countries. The task is immense. A new standard mass will be created with maximum possible precision on a modern level of development for world science and technology. view more (2005-03-03)
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)
Tiny pikas seem to be on march toward extinction in Great Basin

The delayed rise of present-day mammals
It took 10 to 15 million years after the dinosaurs were wiped out before modern mammals-including our ancient human ancestors-were able to diversify and rise to their present-day prominence across the globe, a landmark new study has found. view more (2007-03-29)
Widespread uncontrolled use of antibiotics to prevent anthrax will lead to resistance
Giving antibiotics to large numbers of potentially exposed individuals to prevent anthrax will lead to resistance, according to researchers from Liverpool in this week's BMJ. As such, it is essential that they are used carefully and according to national guidelines. Although generally safe, the antimicrobial drug ciprofloxacin, which has been... view more... (2001-10-31)
Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when the Isthmus of Panama was formed. view more (2007-03-13)
