MIT: Oceans are a major gene swap-meet for plankton

...on among tiny plankton, and the "coinage" they use seems to be a flood of viruses, MIT scientists report. ...lates their populations. And now genetic diversity seems to be an important factor," said Chisholm, who holds appointments in the Department of Civil and Env...

Ancient DNA provides clues to the evolution of social behavior

Novel molecular 'signature' marks DNA of embryonic stem cells

... When combined in this way, the negative influence seems to prevail and, as a result, the genes positioned near bivalent domains are silenced. However, the activating influence appears to keep the genes poised for later activity. "For genes, this is equivalent to resting one finger on the trigger," said St...

Spousal illness can trigger partner death

...ust after the hospitalization of the spouse." "It seems clear that a person's illness or death can have health consequences for others in his or her social network," Christakis says. "This means that efforts to reduce disease, disability, and death can be self-reinforcing, since a decrease in the burden o...

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

...tay on task. It's as if when you're sad, the world seems sadder and all you see is bad news." "Our aim is to reverse that with drug treatment, so we're using these kinds of studies to determine whether particular antidepressants influence the response of that ventral system. And what is particularly excit...

Attractive birds more immune against bird flu

...odies if they have large forehead spots. "Thus it seems that the female uses the forehead spot as a health indicator. When she chooses males with a large forehead spots, she takes not only the healthiest males but also the ones with the best immune defence against future virus infections." The study also...

Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests

...n in an animal's development," says Dr. Troje. "It seems like their brains are 'hard wired' for this type of recognition." One impetus for starting this research several years ago was a question by his young daughter, who asked him why she could get so much closer to wild rabbits in their neighborhood w...

Flu not the only germ threat this time of year

The flu hasn't even hit hard yet this year, but it seems like everyone's getting sick. What's the deal? Simply put, there are a lot more infectious invaders besides the flu to worry about. They don't get the big headlines, but they still knock people down for days or weeks and cause thousands of deaths ea...

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

...ly 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 with animal biology professors Chi-Hing (Ch...

Cuttlefish masters of disguise despite colorblindness

...ontrast threshold, which we would like to know. It seems that cuttlefish camouflage themselves by matching intensities of objects in the environment and we're collecting data to test see whether this is really the case." In addition to looking at contrast between different objects, Mäthger and her colleag...

Protein finding could lead to treatment for inflammatory diseases

...roteins that dampen the immune response, but MC160 seems to be an important one," Shisler said. "Another goal is to design a drug that would override the activity of the protein as a cure for MCV." ...

High resolution 'snapshots' detail dynamics of a cocaine antibody

To reach this ambitious goal, however, it may be necessary to explore new incremental approaches for optimizing the efficiency of such catalytic activity. Novel functional groups could be introduced ...

Component in soy products causes reproductive problems in laboratory mice

"I don't think we can dismiss the possibility that these phytoestrogens are having an effect on the human population," said Dr. Jefferson. "They may not show their effects or be det...

Zebra finches remember songs dad sang

...uman babies have formal similarities, which it now seems they do, then studying the songbird brain can tell us how this imitation trick is actually performed by cells in the brain," Vicario says. "The bird's brain provides a laboratory for studying how memories that underlie vocal learning are stored in th...

Loosen leash on cancer protein 'watchdog,' researchers say

...s needed, acting like a leash on a watchdog. "p53 seems to be an important stress response gene that fights cancer when it works," Mendrysa said. "So we decided to see what we could do to increase p53's activity without completely cutting its Mdm2 leash." The scientists spent three years creating a strai...

Finding a virus is not all bad news

Dr Alexei Drummond, from The University of Auckland's Faculty of Science, has been part of a global research team analysing the genetic sequences of viruses in animals. This pioneeri...

"(Fighting cancer) is the type of work that makes you feel good about being a scientist," she says. "If you can really contribute to humanity and do something that's usefu...

Thinner and younger

Overweight and obese people tend to have higher levels of inflammation than lean people, so it makes sense that losing weight might increase average lifespan by lowering the risks of some age-related diseases, such as diabetes and a...

Alaska seal pup diet may hold key to decline of population

... weaned were less likely to survive the winter. It seems that mother seals, which produce high fat milk, must impart enough fat to get pups over the 26kg mark, Polasek noted. And once weaned, they must ingest sufficient food to get through the winter when food is less abundant. Seals rely on blubber both ...
