New brain hormone puts brakes on reproduction

...ey assistant professor of psychology. "This is an example of the reproductive system being fine tuned," said George Bentley, UC Berkeley assistant professor of integrative biology. "We know a lot about the gross regulation of the reproductive system, but fine tuning hasn't been well understood at all." GnI...

Protein finding could lead to treatment for inflammatory diseases

... "Our findings regarding MC160 provide yet another example of how viruses inhibit NF-kB activation," Shisler said. "So we are starting to get a broader feeling that there is a common mechanism, that of inhibiting NF-kB activity, that all viruses are trying to utilize to survive in the host. What is interesti...

Extinctions linked to climate change

... global amphibian decline said this is another key example of unanticipated and complex impacts from climate change. The Central and South American crisis is "an amphibian alarm call," he said, but also is a harbinger of much greater biological disruption. What had been seen as an enigma is now understood as...

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

...e experience in everyday life," Dolcos added. "For example someone driving on a highway, attempting to pay attention to the driving task might encounter an emotional distracter such as an accident. As everybody knows, at that moment drivers lose focus on the task." "Also, the three types of distracters gave...

Honeybee decision-making ability rivals any department committee

...ifts off toward its new home. "This is a striking example of decision making by an animal group that is complicated enough to rival the dealings of any department committee," said Seeley, a professor of neurobiology and behavior at Cornell and lead author of the article. For more than 10 years, Seeley, Uni...

UCSB researchers discover shape matters to macrophages

...lay or prevent phagocytosis. Such a discovery, for example could allow researchers to design drug carriers that can be purposefully retained by the body for a longer period of time, or could help researchers create vaccines that would be quickly removed to stimulate a rapid immune response. ...

International HIV/AIDS trial finds continuous antiretroviral therapy superior to episodic therapy

... coordinating center director, notes, "SMART is an example of how a large group of investigators around the world can work together to obtain an answer to an important HIV treatment question." Further information concerning the study findings can be found in a Questions and Answers document below. An earlie...

Ticks, flukes, and genomics: Emerging pathogens revealed

... in its regular diet. "This study is a beautiful example of how in-depth comparative genomics can lead to the identification of molecular features that underlie the lifestyle of pathogens," says TIGR molecular biologist Hervé Tettelin, senior author of the PLoS Genetics article. "We could not have reached ...

New hybrid virus provides targeted molecular imaging of cancer

...tumors in the animals," Gelovani says. "This is an example of the so-called "theragnostic" approach, a combination of the words therapeutic and diagnostic." Next, the international collaborative research team plans to evaluate the safety and efficacy of other hybrid vectors in animal models. The ultimate go...

New University of Toronto research a 'pore' excuse for engineering

... for a better insulator," Hatton says. "This is an example of how materials chemistry can provide innovative solutions to the design of novel materials." ...

Darkness unveils vital metabolic fuel switch between sugar and fat

...xcept the brain and kidneys. "This is the first example of a gene that is turned on by darkness, where darkness itself is a signal," Lee said. "Twelve hours of darkness didn't do the job; it had to be at least 48 hours." Tests showed it subsequently took five to seven hours of light exposure to inhibi...

New research demonstrates bone-marrow derived stem cells can reverse genetic kidney disease

...this inherited kidney disease and offers the first example of how stem cells may be useful in repairing basement membrane matrix defects and restoring organ function. Led by researchers at Beth Israel Deaconess Medical Center (BIDMC), the findings are described in the Proceedings of the National Academy of...

World faces challenge as life expectancies lengthen, scientist says

...out." Medical technologies around the globe An example of this inequality, Tuljapurkar said, is the lack of availability of AIDS antiretrovirals in Africa. Although these medications are widely available in the West, they are out of reach for many African patients, who make up more than 60 percent the wo...

Tastier tomatoes in the future?

...open, the pigment that makes tomatoes red, can for example prevent heart disease. Tomatoes furthermore contain a lot of vitamins C and E, indispensable for human nourishment. But after centuries of cultivation for shape, colour, and other useful qualities, our cultured tomatoes today are of small genetic div...

Pleasing plant shapes explained by new computer model

...lop from primordial stem cells. "This was a great example of the synergy you can have between biology and computer science and how the tools of one discipline can be used to answer questions in another," said Prusinkiewicz, who specializes in computer simulations and visualizations in plant biology. " ...

Hyena mothers give their cubs a helpful dose of hormones

...program helped support this work, "this is a clear example of how the complex integration of genetics, physiology and social environment leads to reproductive success for this species." Wolff believes that Holekamp's work will create a paradigm shift in how scientists view the establishment of dominance in ...

Scientists look to the Bahamas as a model for coral reef conservation

... get disease from being infected. The best recent example of this, said Falkow, is H. pylori. First identified only 25 years ago, the organism earned researchers last year's Nobel Prize in Medicine or Physiology for being implicated as a cause of ulcers and stomach cancer. As is typical in the world of mi...

Learning to love bacteria: Stanford scientist highlights bugs' benefits

Computers to save unique type of American red squirrel

...also important ecological reasons to save it - for example the squirrel's middens are an important source of food and habitat for chipmunks, voles, and mice, and the forest would be quite different without these animals. Moreover, if we can't save a species in a relatively controlled, isolated environment l...

Minimal genome should be twice the size, study shows

...a bacterium with desired metabolic properties, for example identifying which genes would a bacterium need to efficiently digest specific waste chemicals. The research has been supported by the Hungarian Scientific Research Fund, EMBO, the Human Frontier Science Program, DFG and the Biotechnology and Biologi...
