UMaine teams with fishermen to study affects of trawling on seafloor ecology

...serve complex bottom habitat, there will be little chance that fishery will ever recover to levels seen 50 or 100 years ago. Small, bottom fish need complex habitat and it is clear that rock hopper gear reduces habitat complexity," said Watling. "No good habitat, hardly any fish." The good news is that rec...

UC Riverside psychologist explores human perception, finds 'wow factor'

...he shape of sound-occluding objects at better than chance levels, with some listeners displaying near-perfect performance," Rosenblum said. That research, he said, seeks a better understanding of how human hearing is affected by silent objects. His projects are all motivated by theoretical questions rather...

High resolution 'snapshots' detail dynamics of a cocaine antibody

...tem- basically soaking up the drug before it has a chance to cross the blood brain barrier-as a potentially effective new approach to treat cocaine abuse." Using a monoclonal antibody endowed not only with high binding ability, but also with sufficient catalytic activity to metabolize cocaine, would have p...

Key heart and Alzheimer's disease protein imaged for first time in native state

...ne apoE4 allele results in an estimated 45 percent chance of developing Alzheimer's by 85 years of age. With two apoE4 alleles, the risk increases to 50?0 percent. "Insights into the basic biology of apoE--and particularly apoE4--gained by Gladstone scientists have been invaluable in the study of Alzheimer...

Multi-million pound UK Biobank underway

... combination of environment, lifestyle, genes ?and chance ?but all studies to date have had limitations, which mean we still don't have a clear picture of how these different elements interact. By being so large and detailed, UK Biobank will be able to study many different risk factors together, each of whi...

Findings advance use of adult stem cells for replacement bone

... program included funding for tuition as well as a chance to begin research in Mikos's lab during her freshman year. "My research experience at Rice has been life-changing in ways I could never have imagined four years ago," Datta said. "I never anticipated I would be traveling to international conferences...

Thin tough skin, slow-growing gills protect larval Antarctic fish

...he department of animal biology. "We finally got a chance to look at the larval fish, and it seems that they don't always have to have antifreeze proteins to survive." Cziko, who earned bachelor's degrees in honors biology and biochemistry in 2004 from Illinois, studied in Antarctica as an undergraduate wi...

Researchers test new way to quit smoking

...kers trying to kick the habit might stand a better chance of staying smoke-free if they begin using replacement nicotine patches or gum in the weeks before they quit cigarettes. That's a theory a team led by the Clinical Trials Research Unit (CTRU) at The University of Auckland's School of Population Healt...

Rhinos clinging to survival in the heart of Borneo, despite poaching

...ah government agencies are hopeful that there is a chance to save this group of rhinos and are diligently working to protect them." In addition to the 13 rhinos found in the interior of Sabah during this survey, a few individuals still survive in other parts of the state that weren't covered in this survey...

How 'hot' emotional brain interferes with 'cool' processing

...e design of these experiments gave us an excellent chance to fill in a missing link in our earlier studies," said Dolcos. "It enabled us to determine whether there was, indeed, a behavioral connection between deactivation of the dorsal system and impaired performance. "The experimental design mimicked the...

Utah researchers confirm chromosome may harbor autism gene

The chance of the same variants of SNPs in a particular region on a chromosome being passed through several generations from a founding couple to multiple affected family members is slight. When such identical blocks of SNPs are found, the chromosomal region of...

The onset of SCA5 usually occurs between the ages of 30 and 50, but can appear earlier or later in life, with reported ages of onset ranging from 4 to more than 70 years...

Study finds drug may cut down involuntary movements

Thirteen years ago the gene that causes the disease was identified by scientists, and now a simple blood test can tell people whether they will develop the disease or not. But since there is no way known to prevent the di...

In the final analysis, Tuljapurkar stressed the need for scientists and policymakers alike to confront the full environmental and sociological imp...

Natural selection at single gene demonstrated

Co-author Magnus Nordborg, associate professor of molecular and computational biology in USC College, predicted that earlier research would need to be revisited because the model makes it too easy to infer selection at any given gene...

There's something fishy about human brain evolution

...y that initial hominid brain expansion happened by chance rather than adaptation. But, he says, the evidence of the importance of key shoreline nutrients to brain development is still with us ?painfully so. Iodine deficiency is the world's leading nutrient deficiency. It affects more than a 1.5 billion pe...

Fruit fly's beating heart helps identify human heart disease genes

...isease in the fruit fly, then there is a very good chance that there is a corresponding gene in humans," Rockman said. "It is an enormous breakthrough to demonstrate that a human gene can induce disease in a fly. With this novel fruit fly model, we can now screen genes we believe are involved in human heart...

Terahertz imaging may reduce breast cancer surgeries

...r the edges, this indicates that there is a higher chance of cancer recurrence. A second operation is required to remove more tissue, involving additional hospital resources and increased risk of patient morbidity. Thus, there is a clinical need to accurately define the margins of the tumor during surgery. ...
