Diatom genome reveals key role in biosphere's carbon cycle

... scientists to tell the species apart. Another new finding reported in Science concerns the unusual way the diatom metabolizes silicon to form its characteristically ornate silica frustule. "Diatoms can manipulate silica in ways that nanotechnologists can only dream about. If we understood how they can des...

An embryonic stem cell model for Parkinson's disease

...eneration remain unknown. Part of the challenge is finding a model that can adequately mimic the loss of dopamine cells. In two papers published in PLoS Biology , Asa Abeliovich and colleagues make the case that a model based on mouse embryonic stem cells offers a promising platform for dissecting the disea...

HHMI researchers Richard Axel and Linda Buck win 2004 Nobel Prize

...identified in this way. The team's most surprising finding was that there are so many olfactory receptors. The 100 different genes the researchers identified first were just the tip of the iceberg. It now appears that there are between 500 and 1,000 separate receptor proteins on rat and mouse--and probably h...

Does a time delay between prostate cancer diagnosis and start of radiation treatment matter?

...ical outcome," Andrews stated. "Another important finding here is that the use of hormone therapy during the treatment delay does not affect outcome and should be avoided in men with favorable risk factors. "Obviously, definitive treatment for prostate cancer should begin as soon as possible after diagnosi...

Brain circuit may permit scientists to eavesdrop on memory formation

...of the journal Nature . According to Schuman, the finding sheds light on a central question in learning and memory research that concerns the roles of two brain structures, the hippocampus, which is involved in memory formation, and the neocortex, which is associated with higher brain functions. "There are ...

...o make it into the actual spores atop the stalk, a finding that surprised the entire research team. The researchers conducted a series of tests to determine whether the dimA mutants had an unexpected competitive disadvantage that was skewing the results of the experiment. One of those tests involved looking ...

Botulism bug says no to nitric oxide, provides key to molecule's role in human cell signaling

...chool at Houston, won the Nobel prize for his 1977 finding that NO is the ingredient that makes nitroglycerine beneficial to heart patients. Since then NO has been found to govern many other vital biological functions and became the basis for medications that treat erectile dysfunction. However, the str...

Sedentary overweight people get insulin boost from short term exercise; CVD risks trend down

... whole-body insulin action." Braun added: "The new finding is that the beneficial effect of exercise (in the short-term) appears to be mediated by a subtle mismatch between energy intake and expenditure. So, the 'exercise' effect can be opposed by adding back the energy expended during exercise. The implicat...

Protein protecting brain from toxins also blocks some chemotherapy from reaching tumors

...unds the brain--the cerebrospinal fluid (CSF). The finding strongly suggests that the natural role of Mrp4 is to block the passage of certain toxic molecules, which chemically resemble topotecan, from leaving the bloodstream and entering the brain. The cells lining the walls of brain capillaries are tightly ...

New method identifies chromosome changes in malignant cells

"The problem is similar to finding typos in a very large book written in a language you don't fully understand," said Troyanskaya, an assistant professor in the Department of Computer Science and the Lewis-Sigler Institute for Integrative Genomics. "All you know are some general rules...

Gladstone researchers resolve key Huntington's disease mystery in Nature cover story

The finding suggests that mutant huntingtin protein inflicts its damage in some form other than as inclusion bodies, which are insoluble, or resistant to being dissolved in liquid. Investigators may now focus attention on the possibility that the real culprit is...

By testing flies with mutations for many other genes, the authors will be able to test more rigorously their suggestion that different genetic pathways underlie these ...
