Cardiac bypass surgery superior to non-surgical procedure for adults with diabetes and heart disease Posted: 04 Nov 2012 06:08 PM PST Adults with diabetes and multi-vessel coronary heart disease who underwent cardiac bypass surgery had better overall heart-related outcomes than those who underwent an artery-opening procedure to improve blood flow to the heart muscle, according to new results.

New device could allow your heartbeat to power pacemaker Posted: 04 Nov 2012 06:08 PM PST An experimental device that converts energy from a beating heart could provide enough electricity to power a pacemaker. Such pacemakers could eliminate the need for surgeries to replace pacemakers with depleted batteries.

Smallholder farmers need improved stake in Nile's development, experts say Posted: 04 Nov 2012 04:31 PM PST A new book finds that the Nile river, together with its associated tributaries and rainfall, could provide 11 countries -- including a new country, South Sudan, and the drought-plagued countries of the Horn of Africa -- with enough water to support a vibrant agriculture sector, but that the poor in the region who rely on the river for their food and incomes risk missing out on these benefits without effective and inclusive water management policies.

Scientists monitor comet breakup Posted: 04 Nov 2012 09:26 AM PST The Hergenrother comet is currently traversing the inner-solar system. Amateur and professional astronomers alike have been following the icy-dirt ball over the past several weeks as it has been generating a series of impressive outbursts of cometary-dust material. Now comes word that the comet's nucleus has taken the next step in its fragmentation.

Advancing understanding of treatment through clinical trials Posted: 04 Nov 2012 05:22 AM PST Medical researchers have new information on drugs being tested in patients with diabetes or kidney disease.

Drug doesn't significantly lower risk of major heart problems in dialysis patients Posted: 04 Nov 2012 05:22 AM PST In one of the largest and longest trials involving patients with kidney failure, a study led by an international team of researchers found that cinacalcet -- a drug commonly prescribed to patients with kidney failure and a disturbance of bone and mineral metabolism known as secondary hyperparathyroidism -- does not significantly reduce the risk of death or major cardiovascular events.

Promising treatment for inherited form of kidney disease Posted: 04 Nov 2012 05:22 AM PST A drug therapy shows promise for treating an inherited form of kidney disease called autosomal dominant polycystic kidney disease, researchers say.

People in 'crowdsourcing' challenge find defibrillators in Philadelphia Posted: 04 Nov 2012 05:22 AM PST Participants in a "crowdsourcing" challenge in Philadelphia used a smart phone application to locate, photograph and map more than 1,400 automated external defibrillators in public places. Although more AEDs are being placed in gyms, schools, shopping malls and public buildings, their exact location is often unknown, and their use remains low.

New research on employment-based insurance sheds light on health care reform Posted: 02 Nov 2012 05:51 PM PDT Men with employment-contingent health insurance who suffer a health shock, such as a cancer diagnosis or hospitalization, are more likely to feel "locked" into remaining at work and are at greater risk for losing their insurance during this critical time as compared to men who are on their spouse's insurance plan or on private insurance plans, according to a new study.

Want to influence support for redistributive tax policies? Choose your words carefully Posted: 02 Nov 2012 01:28 PM PDT Income inequality has become a major topic of discussion over the last year and yet consensus on what (if anything) should be done about it seems elusive. New research suggests that a simple manipulation of language might be able to influence support for policies aimed at addressing income inequality.

New studies reinforce American Heart Association's stand on limiting sodium Posted: 02 Nov 2012 01:28 PM PDT New studies reinforce the American Heart Association's recommendation to limit daily sodium (salt) intake to less than 1,500 milligrams. Suggestions by some groups that healthy people can consume more sodium are based on incorrect analyses of observational studies and misinterpretations of clinical research. Because most dietary sodium comes from processed and prepared foods, the American Heart Association urges health organizations, the food industry and policy makers to provide people with heart-healthy, low-sodium alternatives.

Without adult intervention in concussion management, youth sports can become demolition derby Posted: 02 Nov 2012 01:28 PM PDT Chris Hummel, a concussion researcher and longtime athletic trainer, says coaches, parents and referees need to be educated in recognizing and managing concussions in young athletes. Those adults also need to know when to step in and enforce mandated safety rules.

Building small: In many industries, economies of size is shifting to economies of numbers Posted: 02 Nov 2012 12:19 PM PDT For decades, "bigger is better" has been the conventional path to efficiency in industries ranging from transportation to power generation. Food once grown on small family plots now comes overwhelmingly from factory farms. Vessels that carried 2,000 tons of cargo have been replaced by modern container ships that routinely move 150,000 tons. But now, new research shows, we are on the cusp of a radical shift from building big to building small -- a change that has profound implications for both established and emerging industries.

Overcoming Hurricane stress: Getting a grip after Sandy leaves town Posted: 02 Nov 2012 12:13 PM PDT The upheaval brought about by a natural disaster the likes of Hurricane Sandy forces us to reorganize how we see the world.

Prescription: A healthy dose of no news for election blues Posted: 02 Nov 2012 12:13 PM PDT Whether supporting President Barack Obama or Governor Mitt Romney, this year's election will take people on a roller coaster of emotions from elation to anger depending on the results. To deal with post-election blues, psychiatrists prescribe a strong dose of no TV, radio, social media and Internet coverage.

Researchers help green light the record-breaking 425 mph Jet Reaction bike Posted: 02 Nov 2012 08:51 AM PDT Researchers in the UK could help ensure that a daring Briton soon becomes the fastest man on two wheels, reaching speeds of 425 miles per hour and beyond. Richard Brown is determined to wrest back the world motorcycle land-speed record for Britain with his machine Jet Reaction, powered by an afterburning jet based on a helicopter engine. It develops massive power, but it has taken the team behind the project into new scientific and technological territory.

What would be the effects of nanomaterial use in agriculture? Posted: 02 Nov 2012 05:45 AM PDT The use of nanomaterials in agriculture could, on the one hand, reduce cost and effort, increase efficiency and lead to more environmentally sound applications. On the other hand, it might also have a negative effect on microorganisms in the soil.
