New diagnostic advance seen for head, throat cancer

CORVALLIS, Ore. Pharmacy researchers at Oregon State University today announced the discovery of a genetic regulator that is expressed at higher levels in the most aggressive types of head and neck cancers, in work that may help to identify them earlier or even offer a new therapy at some point i...

Origin of claws seen in 390-million-year-old fossil

New Haven, Conn. A missing link in the evolution of the front claw of living scorpions and horseshoe crabs was identified with the discovery of a 390 million-year-old fossil by researchers at Yale and the University of Bonn, Germany. The specimen, named Schinderhannes bartelsi , was found fos...

High numbers of right whales seen in Gulf of Maine

A large number of North Atlantic right whales have been seen in the Gulf of Maine in recent days, leading right whale researchers at NOAA's Northeast Fisheries Science Center (NEFSC) to believe they have identified a wintering ground and potentially a breeding ground for this endangered species. ...

Aquaculture's growth seen as continuing

Aquaculture production of seafood will probably remain the most rapidly increasing food production system worldwide through 2025, according to an assessment published in the January 2009 issue of BioScience . The assessment, by James S. Diana of the University of Michigan at Ann Arbor, notes th...

Vendee Globe route seen from above

'Nanoglassblowing' seen as boon to study of individual molecules

While the results may not rival the artistry of glassblowers in Europe and Latin America, researchers at the National Institute of Standards and Technology (NIST) and Cornell University have found beauty in a new fabrication technique called "nanoglassblowing" that creates nanoscale (billionth of ...

Lung cancer cells' survival gene seen as drug target

One of the deadliest forms of cancer appears to carry a specific weakness. When a key gene called 14-3-3zeta is silenced, lung cancer cells can't survive on their own, researchers have found. The gene is a potential target for selective anti-cancer drugs, says Haian Fu, PhD, professor of ph...

White blood cells in lung produce histamine seen in allergies

In a surprise finding, scientists have discovered that histamine, the inflammatory compound released during allergic reactions that causes runny nose, watery eyes, and wheezing, can be produced in large amounts in the lung by neutrophils, the white blood cells that are the major component of pus. ...

Single molecular 'mark' seen as pivotal for genome compaction in spores and sperm

In higher order animals, genetic information is passed from parents to offspring via sperm or eggs, also known as gametes. In some single-celled organisms, such as yeast, the genes can be passed to the next generation in spores. In both reproductive strategies, major physical changes occur in the g...

Experimental cancer drugs counter muscle deterioration seen in muscular dystrophy

Muscle weakness and fiber deterioration seen in muscular dystrophy can be countered by a class of drugs currently under study for their effects against cancer, a Burnham Institute study has found. The report shed light on the potential use of these drugs, called histone deacetylase inhibitors, i...

Higher risk for cervical cancer seen among women infected with multiple HPV types

Although doctors have known that the cervical tissue at the opening to the womb can harbor multiple HPV types, this study is the first to document that the risk for developing cervical cancer, the second most common form of cancer in women worldwide, is higher in females infected with multiple HPV ...

Laws that explicitly forbid overexploitation and specify clear rules and targets for rebuilding were seen as an important prerequisite, for example in the U.S. While the study suggests that these tools have long-term benefits, they also come with short...

Health benefits of physical activity more pronounced in women

... The authors speculate that these novel differences may arise from hormonal differences between the sexes, especially considering the extra effects seen post-menopause. The racial differences observed may stem from genetic variations that require further exploration. The authors do also note that t...
