For many biological processes, the Goldilocks Principle rules. You don't want too much, or too little, of something, you want it just right. So it is with the…
Now a new RNA map, created by a team of researchers at Rockefeller University and the Howard Hughes Medical Institute and announced in the journal Nature,…
That's important because E. coli can be spread via recycled solutions used to tenderize and enhance flavor in steaks, chops, and other cuts of meat, said U of…
The biomarkers are micro-ribonucleic acids (micro-RNAs), said Nilamadhab Mishra, M.D. He and colleagues reported at the American College of Rheumatology…
Scientists have found a way of using a protein made by prostate cancer to target and kill the cancer cells themselves. In preliminary studies the new therapy…
The protein, called Arc, has been implicated in memory-linked behaviors ranging from song learning in birds to rodents being aware of 3-D space. In people, Arc…
“In earlier studies, we found that shantytown children in Northeast Brazil who suffer from early childhood diarrhea and malnutrition suffered from lasting…
The study, which was completed in the laboratory of senior author Jack Elias, M.D., the Waldemar Von Zedtwitz Professor and chair of internal medicine at Yale,…
All of these novel findings need much more examination, of course, but scientists at the American Association for Cancer Research's Frontiers in Cancer…
The “evil” cells are clones that have a pre-existing, rather than acquired, resistance to drugs used for treating ALL, and their presence in a patient means…
Researchers investigating ways of prompting the immune system to recognise and kill tumour cells have found that a drug containing parts of the diptheria toxin…
The new virus, which the scientists designate SIVgor, is notable for its close genetic relatedness to an unusual variant of HIV-1 termed ‘group O’ that infects…
In an article in the November 9, 2006, issue of the journal Neuron, published by Cell Press, Kimihiro Nakamura and colleagues report experiments with human…
A central question has been whether the hippocampus receives an “episodic packet,” or a collection of perceptual strands that it must integrate into a memory.In an article in the November 9, 2006, issue of the journal Neuron, published by Cell Press, Melina Uncapher and colleagues report experiments with human volunteers that shed important light on this process….
Scientists have successfully transplanted light-sensing cells called photoreceptors directly into the eyes of mice and restored their visual function. The…
The findings demonstrate that some plants and animals have evolved the same molecular strategy to deter predators — triggering pain by activating a specific…
