| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
