Proton Decay?

Aloyzio AchuttiemAMICOR - 11 minutos atrás
How the death of one tiny particle could end the universe *Esther Inglis-Arkell* No one has observed any evidence for proton decay. That might be disappointing professionally for physicists, but it's good news for the universe. If it turns out to be possible, proton decay could be the beginning of the end of everything. Here's why. How do we start with protons and end with the end of the universe? We begin with what's in those protons. Inside protons are quarks. Quarks are one of the two most basic particles we can find. Quarks are subject to the strong force, the force that keeps a... mais »

FDA Rejects Petition to Pull High-Dose Donepezil Megan Brooks Nov 09, 2012Authors & Disclosures The US Food and Drug Administration (FDA) has rejected a petition by the consumer advocacy group Public Citizen requesting that the agency pull the 23-mg dose of the Alzheimer's disease drug donepezil (*Aricept*, Eisai/Pfizer) from the market because of safety concerns. The FDA action comes roughly 2 months after Public Citizen sued the FDA for not responding to its petition, as reported previously by *Medscape Medical News*. In a response letter dated November 6, 2012, to Sidney Wolfe,... mais »

Blind mole rats may hold key to cancerNovember 6, 2012 [image: Palestine_Mole-rat_1] Blind mole rat (credit: Bassem18/Wikimedia Commons) Some 23% of humans die of cancer, but blind mole rats — which can live for 21 years, an impressive age among rodents — seem to be immune to the disease. Cell cultures from two species of blind mole rat,* Spalax judaei* and* Spalax golani*, behave in ways that render them impervious to the growth of tumors, according to work by Vera Gorbunova at the University of Rochester, *Nature News* reports. “These animals are subject to terrific stresses undergr... mais »

New Drug Class Cuts LDL Cholesterol By Chris Kaiser, Cardiology Editor, MedPage Today Published: November 06, 2012 Reviewed by Dori F. Zaleznik, MD; Associate Clinical Professor of Medicine, Harvard Medical School, Boston ............. "We saw three positive trials, but they are phase II trials showing efficacy and a fair amount of information on safety," he said. "Now we need longer-term safety data and cardiovascular outcomes." In all the trials, patients experienced a robust drop in LDL within the first 2 weeks, which then was sustained out to 12 weeks. AMG 145 (Amgen) and RN136 (... mais »

Treating disease with microbesBugs in the system. Bacterial medicine is starting to emergeNov 3rd 2012 | from the print editionOlONE of the crucial transitions of modern health care was from herbal to chemical medicine. Doctors had known for millennia that willow bark and poppy sap relieve pain. But it was not until the late 19th century, when Felix Hoffman synthesised versions of their active ingredients, namely acetylsalicylic acid and diamorphine (or aspirin and heroin, as they are more commonly known), that proper pharmaceutical science got going. Just possibly, something simil... mais »

Looking Beyond Space and Time to Cope With Quantum Theory ScienceDaily (Oct. 28, 2012) — Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behaviour of the Universe. The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published October 28 in *Nature Physics*. It is based on what the researchers call a 'hidden influence inequality'. This exposes how quantum predictions challenge our best understanding about the nature of space and time, Einstein's theory of rel... mais »
