Successful kidney transplantation despite tissue incompatibility
Donor kidneys can be successfully transplanted even if there is strong tissue incompatibility between donor and recipient. An interdisciplinary working group showed in a study of 34 sensitized high-risk patients that the success rate in these patients was not different from the success rate of patients with a low immunological risk.
UF research provides new understanding of bizarre extinct mammal
University of Florida researchers presenting new fossil evidence of an exceptionally well-preserved 55-million-year-old North American mammal have found it shares a common ancestor with rodents and primates, including humans.
Dogs' anxiety reflects a 'pessimistic' mood Dogs' anxiety reflects a 'pessimistic' mood
Many dogs become distressed when left home alone, and they show it by barking, destroying things, or toileting indoors. Now, a new study reported in the Oct. 12 issue of Current Biology, a Cell Press publication, suggests that this kind of separation anxiety occurs most often in dogs that also show "pessimistic"-like behavior.
Whale poop pumps up ocean health
Whales carry nutrients, especially nitrogen, from the depths where they feed back to the surface via their feces. This waste strongly enhances productivity of fisheries.
This"whale pump," reverses the assumption that whales speed loss of nutrients to the bottom. This nitrogen input in the Gulf of Maine is more than the input of all rivers combined, 23,000 metric tons annually.

What a Scientist Didn't Tell the New York Times About His Study on Bees
Few ecological disasters have been as confounding as the massive and devastating die-off of the world's honeybees. The phenomenon of Colony Collapse Disorder (CCD)--
in which disoriented honeybees die far from their hives--has kept scientists, beekeepers, and regulators desperately seeking the cause. ...
SETI Participant Claims He Found A Signal From Near Gliese 581 Already
Astronomers are certainly not strangers to manipulating public relations through mass media - they write reasonable papers and then encourage the press to go nuts with it.
Witness the recent arXiv paper by Vogt, Butler, et al on Gliese 581g, should it even exist, which reads
Why it's hard to crash the electric grid
A new study shows why it would be hard for terrorists to bring down the US electric grid.
Moonlighting as a Conjurer of Chemicals
The scope and details of Sir Isaac Newton’s interest in alchemy are only now becoming clear.
Observatory: Salt Infusion Could Be a Remedy for Damaged Cells
An infusion of sodium helped tadpoles regenerate amputated tails.
Vital Signs: Mental Health: Fog May Be From Cancer, Not the Chemo
Cancer survivors often complain about the mental fog of “chemo brain.” But the problem may not be limited to cancer patients who undergo chemotherapy, a new study suggests.
Rotten experiments help to create picture of our early ancestors
How can watching primitive fish rot away reveal answers to the fundamental questions of how, when and why our earliest vertebrate ancestors evolved? An innovative experiment at the University of Leicester that involved studying rotting fish has helped to create a clearer picture of what our early ancestors would have looked like.
Melanoma drug shrinks brain metastases in phase I/II study
A new drug being developed to treat potentially deadly melanoma skin cancers has shown a promising ability to shrink secondary tumors, known as metastases, in the brain in patients with advanced forms of the disease, Australian researchers report.
Tiny tubes point to ancient life
Microscopic tubes thought to have been etched into South African rocks by microbes 3.3 billion years ago have had their great antiquity confirmed.
Human Ancestors Hunted by Prehistoric Beasts
Early humans appear to have occupied a much lower link of the food chain than their modern counterparts.
Prenatal treatment of congenital toxoplasmosis could reduce the risk of brain damage
Prenatal treatment of congenital toxoplasmosis with antibiotics might substantially reduce the proportion of infected fetuses that develop serious neurological sequelae (brain damage, epilepsy, deafness, blindness, or developmental problems) or die, and could be particularly effective in fetuses whose mothers acquired Toxoplasma gondii, during the first third of pregnancy.
Compound in celery, peppers reduces age-related memory deficits
A diet rich in the plant compound luteolin reduces age-related inflammation in the brain and related memory deficits by directly inhibiting the release of inflammatory molecules in the brain, researchers report.
Planet hunters no longer blinded by the light
UA astronomers have developed a way to see faint planets in faraway solar systems previously invisible to Earthly eyes. The technique "opens new doors in planet discovery," said Phil Hinz, director of the UA's Center for Astronomical Adaptive Optics at Steward Observatory.
Low beta blocker dose can put patients at risk for subsequent heart attacks
In a breakthrough study, a Northwestern Medicine cardiologist finds the majority of patients are putting their recovery from heart attacks into peril by taking an incorrect dose of beta blockers.
Researchers develop method for curbing growth of crystals that form kidney stones
Researchers have developed a method for curbing the growth of crystals that form cystine kidney stones. Their findings may offer a pathway to a new method for the prevention of kidney stones.
Overseas nurses feel their skills are underused and they aren't valued or respected
Since 1997, 100,000 overseas nurses from 50 countries -- led by the Philippines, India, South Africa and Australia -- have registered in the UK. But retention is an ongoing issue. A detailed review has found that many overseas nurses have negative experiences of living and working in the UK, as they don't feel personally valued and professionally respected.
Scientists suggest that cancer is purely man-made
Cancer is a modern, man-made disease caused by environmental factors such as pollution and diet, a study by University of Manchester scientists has strongly suggested.
Bilingualism Good for the Brain
The longer a person has spoken two or more languages, the greater the cognitive effects.
First TB vaccine booster unveiled by Seattle scientists
Seattle scientists have developed a tuberculosis vaccine that may boost the effectiveness of the only existing vaccine, extending immunity against the disease.
Study confirms: Whatever doesn't kill us can make us stronger
We've all heard the adage that whatever doesn't kill us makes us stronger, but until now the preponderance of scientific evidence has offered little support for it. A new national multi-year longitudinal study of the effects of adverse life events on mental health has found that adverse experiences do appear to foster subsequent adaptability and resilience, with resulting advantages for mental health and well being.
Wind turbines 'lure in' animals
Wind turbines attract insects, which may explain why their blades strike and kill significant numbers of insect-eating bats and birds.
Giant Pterosaurs Could Fly 10,000 Miles Nonstop
Flying reptiles as tall as giraffes could soar nonstop up to 10,000 miles, burning fat stores equal to an adult human, new research says.
