Study finds 60 new genes controlled by DNA snippet

...a set of criteria that a given piece of DNA had to meet in order to be considered a functional CArG box. Thanks to their work and that of several other labs, they knew going in all the CArG box variations and how close they typically lie to the genes they regulate (within 4,000 base pairs). The data-scre...

Losing sleep undoes the rejuvenating effects new learning has on the brain

...comes harder to balance home and work, many people meet their obligations by getting less sleep. But sleep deprivation impairs spatial learning -- including remembering how to get to a new destination. And now scientists are beginning to understand how that happens: Learning spatial tasks increases the p...

UCSD team unmasks family of immune system invaders

...eria pass into the intestine and colon, where they meet up with a layer of cells lining these organs called the epithelial cells. The epithelial cells form a protective wall without any doors, a barrier that blocks bacterial entry from the intestine and colon into the rest of the body. However, bacteria...

World shark attacks dipped in 2005, part of long-term trend

...tten, and on the rare occasion where they actually meet up with a shark, are doing the right thing to save their lives," he said. In one such case, a surfer bitten by a great white shark off the Oregon coast on Dec. 24 had the presence of mind to drive it away with a well-timed punch to the nose, he said...

Chemical guidance of T cells leads to immunologic memory and long-term immunity

...Germain. If passengers know that limo drivers will meet them in the terminal, they will look for their drivers upon arrival. Rather than hoping to run into each other by chance, the drivers crowd around the arrival gates and hold up signs that the passengers can read from a distance. Moreover, CD8+ T ce...

Dr Ferguson said the EST database has already helped expand scientific understanding of apple, enabling HortResearc...

Warbling whales speak a language all their own

...the authors do not claim that humpback whale songs meet the linguistic rigor necessary for a true language. "Humpback songs are not like human language, but elements of language are seen in their songs," said Ryuji Suzuki, a Howard Hughes Medical Institute (HHMI) predoctoral fellow in neuroscience at Mas...

New RNAi tools enable systematic studies of gene function

...viral delivery is an especially effective means to meet this need." The parallel analysis of thousands of genes using RNAi allows researchers to more readily pinpoint the genes that control a biological process. Therefore, TRC developed the high-throughput techniques and quality-control measures required...

Sustainable farm practices improve Third World food production

...hough it is uncertain whether these approaches can meet future food needs, there are grounds for cautious optimism, particularly as poor farm households benefit more from the their adoption," Pretty says. ...

Climate change: The rice genome to the rescue

...ms facing rice production in Asia ?and continue to meet the demand for rice in the region ?yields will have to double over the next 50 years. Research has confirmed that global warming will make rice crops less productive with increasing temperatures decreasing yields. "Clearly, climate change is going t...

Alcoholism, smoking and genetics among Plains American Indians

...cs drink heavily, but episodically ?yet they still meet the criteria for alcoholism." Two, she continued, "they have a very different comorbidity. They don't smoke heavily." In statistical terms, although 62 percent of the male alcoholics and 40 percent of the female alcoholics were smokers, only 12 pe...

Diabetes researchers pioneer islet cell xenotransplantation in primate studies

... in primates," said Drs. Korbutt and Rajotte. "To meet the needs of the millions suffering from type 1 diabetes, we must find new donor sources to allow large-scale application of islet cell transplantation in humans," said Dr. Larsen. "While there is much work to be done these studies suggest that the r...

Stem cells from muscles can repair cartilage

...e (cartilage covering the ends of bones where they meet in a joint) frequently occurs due to injury or illness, and can lead to degenerative disease. Treatments and experimental approaches to repair this articular cartilage have achieved limited results, but currently there is no method to fully restore t...

Picking particles faster than one at a time

...atic particle-picking methods have been devised to meet this challenge, but until now even the best yield more than 30 percent false positives -- either poor-quality images of particles or something else altogether, like debris or background noise. Therefore "a human still has to go through them and pick ...

UCR environmental scientists propose chemical solution to cleaning California's Salton Sea

...t development of the surrounding region could help meet the needs of California's growing population, support commercial growth in the neighboring Imperial and Coachella Valleys and achieve high property values in an area that is easily accessible from cities such as Los Angeles, San Diego and Riverside. ...

Worms know bad food when they smell it

...a. As it writhes through its world, the worm might meet up with hundreds of different species of bacteria in as little as five minutes. But while some bacteria make ideal worm food, others are toxic. "The worm swallows them and then they establish an infection inside the worm's gut and they proliferate ...

After initial treatment and evaluation, a pediatric surgeon will approach the injured child's parents to explain the trial and request permission to enroll the child in the study. If permission is granted, bone marrow...
