UF scientists reveal ancient origin of vertebrate skeleton

... basically have a head at one end and cartilage to hold it together, but no bone. But this work says the common feature of vertebrates is not the presence or absence of bone, but the presence of a shared gene system that produces cartilage. This conclusion is illuminating and extremely important." ...

Largest study of human 'interactome' reveals a novel way

...ysis of interactions between proteins in our cells hold promise for identifying new genes involved in genetic diseases, according to researchers at Johns Hopkins and the Institute of Bioinformatics (IOB) in Bangalore. The findings, reported in the March issue of Nature Genetics, were made using a databas...

Researchers unlock how cells determine their functions

...ells during animal development. The findings could hold promise for the advancement of cancer and stem-cell research. The research is published in the Feb. 24 edition of the journal Science. UCR Biochemistry Professor Frank Sauer, with German colleague Elisabeth Kremmer of the Institut für Molekulare Im...

Collaborators on the study include research and development engineer Edward Light, assistant professor of pediatrics Salim Idriss, Pratt undergraduate Kathryn Sulli...

Source of crucial immune cell in the skin discovered

...y, the researchers point out that the new findings hold promise for potential therapeutic for patients with a Langerhans histocytosis, a rare disease effecting approximately 200,000 children annually. In children with this disorder, large numbers of Langerhans cells infiltrate organs and tissues throughou...

Common molecular 'signature' identified in solid tumors

...tic pathways that become scrambled as cancer takes hold and spreads. He says narrowing the list of the most active ones provides a guide to directing future research. "We know that there are hundreds of miRNAs, and some of them may have multiple gene targets. Finding the ones that appear over and over a...

A salty tale: New bacterial genome sequenced from ancient salterns

...trikingly stable. And that means the bacterium may hold promise for industrial applications. Meanwhile, TIGR's collaborators are pursuing studies of Spain's salterns, testing the ponds to find out what other microbes call the briny waters home. "How much diversity is there?" Mongodin asks. "We'll all be i...

Stress substantially slows human body's ability to heal

... are key elements in the human immune system. They hold a delicate balance in maintaining the right immune response. Increased levels of IL-6 at the site of a wound stimulate the healing process but those same levels circulating throughout the bloodstream is a problem. Sustained higher-than-normal level...

Researchers use 'trickery' to create immune response against melanoma

Cheap, rapid hand-held check for HIV

...chip bearing these electrodes, the antibodies grab hold of the CD4+ cells. The captured cells then impede the flow of current across the electrodes, allowing the density of CD4+ cells to be calculated. To check that only CD4+ cells were sticking to the electrodes the team added a label to blood samples ...

New research examines genetics of successful aging

'Creationism is not science' ?making the case for Darwin at UCL

Can the hold that Intelligent Design theorists have in America be broken by the evolutionists? Professor Michael Ruse, a leading American evolutionist, makes the case for Darwin in The Annual Robert Grant Lecture, "Darwin or Design? Reporting from the front lines...

The attempt was successful: in the fly data, for example, 26 sets of proteins seemed to be interacting through linear motifs. "One challenge was to eliminate red herrin...

Bare metal stents deliver gene therapy to heart vessels with less inflammation in animal studies

...estenosis, but the polymer coatings that initially hold the drugs to the stents may stimulate inflammation. The inflammation in turn leads to restenosis. Researchers at The Children's Hospital of Philadelphia have developed a novel technique to attach therapeutic genes to a stent's bare metal surface. Th...

Same-sex mating by fungi spawned infection outbreak, evidence suggests

"While the number of people infected so far does not approach that of many other infectious diseases, this fungus is invading the central nervous sy...

Science's Breakthrough of the Year: Watching evolution in action
