Tropical Birds Have A Slower Pace of Life

In the tropics, even the birds know how to relax better than those in the north. Tropical birds expend less energy at rest than do birds living in more northern climates, according to a study published online this week in the Proceedings of the National Academy of Sciences.Take a tip from tropical birds. Enjoy life a little.

Scientists building "Ice Top" for a telescope - at the bottom of the world

The University of Delaware is helping to build a huge "IceCube" at the South Pole, and it has nothing to do with cooling beverages.

"IceCube" is a gigantic scientific instrument--a telescope for detecting illusive particles called neutrinos that can travel millions of miles through space, passing right through planets.The IceCube telescope's optical detectors are deployed in mile-and-a-half deep holes in the Antarctic ice.

Study Focuses on Only Carnivore with 'Fingerprints'

A new study in the May issue of the Journal of Wildlife Management reports that scientists from the New York State Museum, Wildlife Conservation Society and other groups have teamed up with the New York State Department of Criminal Justice to developed a new technique that uses fingerprints to track the fisher--an elusive member of the weasel family, and the only carnivore species known to have unique fingerprints.Scientists recovered this camera trap photo of a fisher, an elusive member of the weasel family.

Biologically active paper holds promise for improved global health

Next time there is a global pandemic, contaminated water caused by flooding, or questionable-looking meat in a supermarket, we may be reaching for a piece of paper.

It won’t be just any type of paper but a Canadian-invented bioactive paper that contains the ingredients to detect and ward off life-threatening bacteria and viruses like E-coli, salmonella and SARS, to name just a few.

Botulism bug has few genome wrinkles

The genome of the organism that produces the world's most lethal toxin is revealed today. This toxin is the one real weapon in the genome of Clostridium botulinum and less than 2 kg - the weight of two bags of sugar - is enough to kill every person on the planet. Very small amounts of the same toxin are used in medical treatments, one of which is known as Botox®.

Moderate drinking lowers women's risk of heart attack

Women who regularly enjoy an alcoholic drink or two have a significantly lower risk of having a non-fatal heart attack than women who are life-time abstainers, epidemiologists at the University at Buffalo have shown.

Moderation is the key, however. Women in the study who reported being intoxicated at least once a month were nearly three times more likely to suffer a heart attack than abstainers, results showed.

Tiny genes may increase cancer susceptibility

New evidence indicates that small pieces of noncoding genetic material known as microRNAs (miRNAs) might influence cancer susceptibility. Differences in certain miRNAs may predispose some individuals to develop cancer, say researchers.

Long-term ulcerative colitis study shows Remicade responders maintained improvement

Findings presented today at Digestive Disease Week® 2007 (DDW), from long-term extensions of the ACT trials (Active Ulcerative Colitis 1 & 2) show that subjects with moderately to severely active ulcerative colitis (UC) who had responded to REMICADE® (infliximab) in the blinded phase of the trials maintained improvement in their clinical symptoms for up to two years.

In new statistical approach, data decide models

A data-driven computational approach developed by a University of Illinois statistician is revealing secrets about inner Earth and discovering unique gene expressions in fruit flies, zebra fish and other living organisms.

"Using mathematical concepts from inverse scattering and modern statistics, we let the data 'speak,' and automatically generate an appropriate model," said Ping Ma, a professor of statistics at the U. of I. and lead author of a paper describing the technique that has been accepted for publication in the Journal of Geophysical Research.

Coming: plants that produce more vitamin C

UCLA and Dartmouth scientists have identified a crucial enzyme in plant vitamin C synthesis, which could lead to enhanced crops. The discovery now makes clear the entire 10-step process by which plants convert glucose into vitamin C, an important antioxidant in nature.

Botox for prostate problems

Botox is not just for keeping aging actresses looking eerily young any more. Injecting botulinum toxin A, or Botox, into the prostate gland of men with enlarged prostates eased symptoms and improved quality of life for up to a year after the procedure.

The study was based on 37 men with benign prostatic hyperplasia (BPH).

Aspirin to prevent colon cancer?

A colon cancer researcher at the Ireland Cancer Center of University Hospitals Case Medical Center (UHCMC) has laid out the roadmap for how medical science should employ aspirin and new aspirin-like drugs for use in preventing colon cancer in certain high-risk individuals.

Some stem cells may look mean but act nice

Call it the cellular equivalent of big glasses, a funny nose and a fake mustache.

Bone marrow stem cells attracted to the site of a cancerous growth frequently take on the outward appearance of the malignant cells around them, University of Florida researchers report in a paper to be published in the August issue of Stem Cells.

Resistance genes in our food supply

Could the food we eat be contributing to the continuing rise of antibiotic-resistant infections? Harmless and even beneficial bacteria that exist in our food supply may also be carrying genes that code for antibiotic resistance. Once in our bodies, could they transmit the resistance genes to disease-causing bacteria?

Canadian study says blacks in America perceive people with health problems as less valuable

Leave it to white Canadians to tell African-Americans how they feel about people with health problems.

A study by the University of Alberta, published in the Journal of Clinical Epidemiology, says African Americans appear to perceive people with extreme health problems as less productive or valuable

The study examined the differences in preferences for the EQ-5D health states among African Americans, Hispanics, and other races living in the United States.
