Doctors have used drugs to induce general anesthesia in patients undergoing surgery since a medical doctor became a legitimate profession in the mid-1800s.  But little has been known about how these drugs create such a profound loss of consciousness. We don't understand why aspirin works either, but it does.  Yet the search for answers about the brain is ongoing. 

When a marathon runner approaches the finish line of race but suddenly collapses, it's reasonable to assume it is because of a muscle issue. It might also be a braking mechanism in the brain which swings into effect and makes us people tired to continue. What may be occurring is what is referred to as 'central fatigue'.

A survey analysis finds both that the public is supportive of government action to curb obesity, diabetes, and other noncommunicable diseases - but don't like interventions that appear intrusive or coercive.

The Harvard School of Public Health (HSPH) analysis also found that support was higher for interventions that help people make more healthful choices, such as menu labeling requirements, than for interventions that penalize certain choices or health conditions, such as charging higher insurance premiums for obese individuals.

If your children stump you with 'cite your data' claims on why they need to eat leafy green vegetables, even though we got to the top of the food chain so we wouldn't have to do that, here is good news; a new study found that that an immune cell population essential for intestinal health could be controlled by leafy greens in your diet.

Last week a new important paper appeared in the Arxiv: "MSSM Higgs Boson Searches at the LHC:Benchmark Scenarios after the Discovery of a Higgs-like Particle", by M.Carena, S.Heinemeyer, O. Stal, C.Wagner, and G.Weiglein. The paper fills a void that was created after the discovery of the Higgs particle last July by the ATLAS and CMS experiments: a thorough assessment of what constraints on the allowed chunks of SUSY parameter space in the light of the existence of a neutral scalar at 125 GeV.

Richard Mankiewicz, our man in Bangkok, also known as Red Man (see his profile – no no, not because of Bangkok’s red light district - that would be Stickman, not Red Man!) has started a Math Puzzle Column on Science2.0, first entry: Circles Stuck in a Triangle.

In President Obama's most recent State of the Union address, he mentioned neuroscience three times. One was a stated commitment to ensure top-quality mental healthcare for returning soldiers. One was the reference to the effect of early education on child learning and performance (I know it's a stretch, but I'm counting it. They aren't learning with their livers.) And third was a reference to brain mapping that could "unlock the answers to Alzheimer’s". A short time later, the President proposed a new, ambitious federal Brain Activity Map project. You may question many of the President's positions, but he's clearly pro-brain, and that's good.

As readers of this blog know, I am not sympathetic to extreme reductionism, and reject both it and determinism in favor of a robust concept of emergence.

Though staunchly opposed to nuclear power in some respects, like the controversial decision to scuttle the Yucca Mountain project, the Obama administration said in 2012 that it was "jumpstarting" the nuclear industry.

While America moves toward an egalitarian approach to medical care, another study has found that the quality of cares matters in things like advanced head and neck cancers.

The paper in Cancer says that patients who were treated at hospitals that saw a high number of head and neck cancers were 15 percent less likely to die of their disease as compared to patients who were treated at hospitals that saw a relatively low number. The study also found that such patients were 12 percent less likely to die of their disease when treated at a National Cancer Institute -designated cancer center.
