A drug that makes you not only able but eager and willing isn't going to remain the exclusive property of the severely impaired. As with Viagra, there will be extensive off-label use.—Julian Dibbell, The Observer
The molecular functions of Folliculin (FLCN) are poorly understood, but indirect interactions between FLCN and AMPK (of the mTOR signaling network) mediated by FNIP1 and FNIP2 have been firmly established (Baba M et al, 2006; Hasumi H et al, 2008; Takagi Y et al, 2008), suggesting a role for FLCN in nutrient/energy-sensing through the AMPK/mTORC1 signaling pathway.
Intervals of regional warmth and cold in the past are linked to the El Niño phenomenon and the so-called "North Atlantic Oscillation" in the Northern hemisphere's jet stream, according to a team of climate scientists. These linkages may be important in assessing the regional effects of future climate change.
Heidelberg, 27 November 2009 -- What are the bare essentials of life, the indispensable ingredients required to produce a cell that can survive on its own? Can we describe the molecular anatomy of a cell, and understand how an entire organism functions as a system?
COLLEGE PARK, Md. - Advances in computerized modeling and prediction of group behavior, together with improvements in video game graphics, are making possible virtual worlds in which defense analysts can explore and predict results of many different possible military and policy actions, say computer science researchers at the University of Maryland in a commentary published in the November 27 issue of the journal "Science."
Darwin suggested that the action of natural selection can produce new species, but 150 years after the publication of his famous book, 'On the Origin of Species', debate still continues on the mechanisms of speciation.
The copper sequestering drug tetrathiomolybdate (TM) has been shown in studies to be effective in the treatment of Wilson disease, a disease caused by an overload of copper, and certain metastatic cancers. That much is known. Very little, however, is known about how the drug works at the molecular level.
MRSA (methicillin-resistant Staphylococcus Aureus) and other drug-resistant bacteria could face annihilation as low-temperature plasma prototype devices have been developed to offer safe, quick, easy and unfailing bactericidal cocktails.
For the first time guidelines are to be published on how broadcasters around the world can encourage audiences to produce better quality user-generated content and to improve media and information literacy.
The new guidelines will also enable the public to become more media and information literate.
CINCINNATI -- A new study from researchers at the University of Cincinnati (UC) and the Cincinnati Department of Veterans Affairs Medical Center reaffirms that some patients with HIV experience an improved quality of life following their diagnosis.
These findings are being published in the November issue of the journal AIDS Patient Care and STDs.

Search the Internet to learn about your asthma, high cholesterol or other common disorder, and odds are you'll be directed to a pharmaceutical company-sponsored Web homepage. There you'll often find an offer for a free sample or a one-time discount on a top-selling prescription medication.
CAMBRIDGE, Mass. -- A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week in the journal Science Translational Medicine.
When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.
Athens, Ga. -- Bacteria don't have easy lives. In addition to mammalian immune systems that besiege the bugs, they have natural enemies called bacteriophages, viruses that kill half the bacteria on Earth every two days.
