Biologists find regions of rice domestication

...r instance, one direction that the researchers are going is Thailand, where the Karen tribe has been using ...passed down many generations, Schaal said. "We're going to try to find out how landrace varieties change after domestication," Schaal said. "These landrace...

UNH researcher restoring oyster reefs to Great Bay

...ng 20 acres of oyster reefs by 2010. "I hope we're going to have a bay with a healthy oyster population, and we're going to work hard to do it," he says. His research explores which are the best reef restoration technique...

Triple threat polymer captures and releases

... ?are "strange, if not weird, but there is so much going on here, we want to explore it all.." That weirdness suggests equally weird mechanical properties. Wooley and her post doctoral researcher Jinqi Xu, Ph.D., are exploring those properties and one essential irony ?the material, similar to a hydrogel...

C-myc required by the immune system

Female guppies risk their lives to avoid too much male attention

...[sexual segregation] occurs is essential if we are going to conserve and protect species and habitats," explains Croft, who points out that fish are not the only species who display this social characteristic. "In many ecosystems, predators are the first to go extinct, and our work shows that this may have...

Leptin found to control appetite and limb development in frogs

...d a different response to the hormone. Rather than going off their feed as the older frogs did, these tadpoles kept right on eating and quickly sprouted limbs. Denver, who has studied the ability of frogs to speed up their metamorphosis in response to a drying pond, thinks that the tadpoles' feeding mech...

Researcher studies, treats military with 'silent disease'

...ious. They think they have HIV or something that's going to kill them overnight," she said. "We like to talk to the patient and put them at ease, and say 'Look this is the story, let's work together.'" Having the disease doesn't end a military career. Military members who have it can still deploy, though...

A sweet solution for Alzheimer's disease?

...rge-Hyslop said. "Alzheimer's disease is probably going to be treated by a cocktail of drugs," he predicted. "Some of them might be this compound, or one like it, that blocks the toxicity and aggregation of amyloid." ...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

... mystical experiences. "I had a healthy skepticism going into this," says Griffiths, "and that finding alone was a surprise." But, as important, he says, "is that, under very defined conditions, with careful preparation, you can safely and fairly reliably occasion what's called a primary mystical experienc...

Study shows frogs can play key role in stem cell research

...e when they will decide what type of cell they are going to be. This is probably what Oct4 is doing in mouse and human embryonic stem cells. The findings are also interesting because they highlight that the remarkable capacity of embryonic stem cells to divide without limit is at least 300 million years o...

UC Davis researchers reveal apples' protective ways

...e case of apples, we have a good idea about what's going on," said Eric Gershwin, professor of allergy, rheumatology and immunology at the UC Davis School of Medicine. Gershwin and his colleagues found that apple extract was able to protect cells from damage and death by interfering with communication bet...

Vampire bats recognise their prey's breathing

The vampire bats were able to spontaneously associate the clips with the particular individuals, regardless of whether the i...

Time of day tempers tadpoles' response to predators

...risk may still be fairly high and the tadpoles are going to feed very little anyway. That means the growth rate-to-predation risk ratio is low. At night, the ratio is higher because that's when the tadpoles do most of their feeding. This favors a quicker return to their pre-cue activity levels." Consider...

Bacteria can help predict ocean change

"We expect to need data from at least 1,000 such individuals in order to define the genetic factors associated with this extraordinary outcome," she adds. "This effort will only be possible with the collaboration of HIV researchers, providers...

Spinal cord bridge bypasses injury to restore mobility

...rs. Silver describes them as "trucks stuck in mud going no where." It also explains why some people gain some movement back or come out of comas after many years as the nerve fibers sprout through weakened or remodeled areas of the scar. About 16 years ago, Silver also made another find that proteoglyc...

MIT 'seeing machine' offers hope to blind

NASA technology helping injured US troops

...When we first put him in the walker, he was up and going for 25 minutes," explained Messier. "He's now walking for up to 25 minutes every day and even using SAM to perform exercises to strengthen his leg muscles." The SAM walker, born by way of NASA's technology transfer program, also gives patients with...

RNA interference stops colon cancer spread in mice

To study the effects of siRNAs targeted against the PI3K pathway in mice, the researchers used a well-established technique in which human colorectal cancer cells were implanted into the spleens of genetically engineered immu...
