Infants can organise visual information at just four months

...lookers' and shift visual attention rapidly, while others are 'long-lookers' who keep their attention fixed for longer. Previously, these categories were thought to be relatively stable traits indicative of individual differences, with links to later cognitive development. However, the research revealed t...

Growth hormone is made in the brain, report scientists

...re of the brain. Several studies in our lab and in others have shown that males learn differently than females. It is possible that sex differences in these hormones are somehow involved." ...

Tiny polyps gorge themselves to survive coral bleaching

...eaching events, some corals quickly died off while others close by were able to recover. To answer that, she returned to Hawaii Institute of Marine Biology where she has been studying corals for the past 13 years. There, she and her collaborators focused on two types of common coral that thrived on the lo...

Scientists discover interplay between genes and viruses in tiny ocean plankton

...information that drives their core metabolism, and others that are more mobile, which can be found in unique combinations in different microbes." The distributors or carriers of new genes, the scientists suspect, are the massive numbers of viruses also known to exist in seawater. Some of them are adept at ...

Invasive species harms native hardwoods by killing soil fungus

...duced. Some alien species cause little harm, while others can become very aggressive and radically transfigure their new habitat. "The mechanisms for this phenomenon and its potential long term impacts remain poorly understood," Stinson adds, "but one possibility is that invasive species may disrupt fragil...

Ernst Mayr's theory illustrated in genetic epidemiology studies

...actors, some genes seem to play a larger role than others at any given time. "The real causation of the trait is at the interaction level and not the single gene level, and therefore if you change just the frequency of the gene you'll change what's major and what's minor, and that's another way of saying y...

Driver of anthrax toxicity could lead to late-stage therapy

...niversity School of Medicine in collaboration with others at Stanford and the National Institutes of Health. The level of anthrax protection afforded by the antibodies rose with increasing dose. Anthrax is a lethal disease of humans and other animals caused by the spore-forming bacteria Bacillus anthracis,...

Junk DNA may not be so junky after all

Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice

Cell therapy slows progression of an inherited neurological disease; Improves motor skills in mice

...such as myelin-producing cells, may be better than others when used for therapy." "These results contribute to a growing field of intense research where the use of brain-derived cells, including myelin-producing cells and neural stem cells, may be envisioned as direct cell therapies to target specific neur...

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

...information that drives their core metabolism, and others that are more mobile, which can be found in unique combinations in different microbes. "So it is these unique combinations of genes that create the diversity we see, and which allow microbes to flourish in all environments on Earth," she added. "And...

Study finds drug may cut down involuntary movements

...patients are affected as early as childhood, while others aren't affected until their older years. Virtually everyone with the disease had a parent with the disease, and children of a person with Huntington's have a 50-percent chance of inheriting the disease. Thirteen years ago the gene that causes the d...

Powerful technique for multiplying adult stem cells may aid therapies

...p into all of the red and white blood cells, while others form the immune system. Using fetal tissue from mice as the source of these cells, Zhang discovered a population of cells that were not stem cells, yet appeared to interact with stem cells, preserving and allowing them to multiply in the fetal enviro...

Clock molecule's sensitivity to lithium sheds light on bipolar disorder

... Rev-erb, a receptor shown previously by Lazar and others to play a role in maintaining normal metabolism, is prevented by GSK3 in mouse and human cells. "It's like pulling a pin out of the gears of the clock, to allow them to turn in a synchronized manner," says Lazar. Lithium blocks this action of GSK3, ...

Waking a sleeping virus

...for the virus during its latent state, whereas all others are necessary to produce new viruses and to infect new host cells. Those have to be switched on, and ZEBRA functions as the switch which turns the cell into a factory to manufacture thousands of copies of the virus." One result is the disease infec...

Ticks, flukes, and genomics: Emerging pathogens revealed

...many different pathogens, some closely related and others diverse, we're able to identify genes linked to different diseases and organisms," explains molecular biologist Julie Dunning Hotopp of TIGR, first author of the PLoS Genetics paper. Because the pathogens causing ehrlichiosis are obligate intracellul...

When mice choose mates, experience counts

...tly provided by an individual, such as odor, which others observe use to make decisions such as mate choice, food location, or presence of danger. Specifically in birds and fish, 'public information' has been shown play a role in when and what to eat and with whom to mate with, but its use in mate choice ha...

Gene therapy 'turns off' mutation linked to Parkinson's disease

...o selectively turn off one gene in a cell, leaving others unaffected. By placing the RNA interference into a crippled, non-disease-causing virus, scientists in the Bohn lab have been able to deliver the RNA interference tool to the brain of rats and turn off the alpha-synuclein protein in neurons. "This i...
