Sonic ‘lasso’ catches cells and moves them around

Posted on by

“Academics have demonstrated for the first time that a ‘sonic lasso’ can be used to grip microscopic objects, such as cells, and move them about. The researchers have shown experimentally how tiny particles, such as cells, or any small objects can be trapped by a spinning ultrasonic, or sonic, vortex. The vortex acts as a lasso that can be controlled and moved, catching the microscopic particles and enabling their careful positioning.  This new technology makes possible applications such as assembly human tissue from a collection of cells and assembling nano materials.”

Scientists use iPhones to diagnose intestinal worms

Posted on by

“Scientists used an iPhone and a camera lens to diagnose intestinal worms in rural Tanzania, a breakthrough that could help doctors treat patients infected with the parasites, a study said on Tuesday.  Research published by the American Journal of Tropical Medicine and Hygiene showed that it is possible to fashion a low-cost field microscope using an iPhone, double-sided tape, a flashlight, ordinary laboratory slides and an $8 cameral lens.  The researchers used their cobbled-together microscope to successfully determine the presence of eggs from hookworm and other parasites in the stool of infected children.”

Study: Low Doses Of THC Provide Cardioprotection

Posted on by

“Low doses of THC are cardioprotective in mice, according to preclinical data to be published online in the journal Biochemical Pharmacology.  Israeli scientists assessed in impact of a single ‘ultra-low’ injection of THC in mice prior to ischemia (the restriction of blood supply to tissues). Investigators reported that THC ‘is a safe and effective treatment that reduces myocardial ischemic (heart attack) damage.'”

No proof that helmets prevent concussion: experts

Posted on by

“Helmets and mouthguards can prevent serious head and facial injuries, but there is no evidence they specifically stave off concussion, top authorities in sports medicine say.  Paradoxically, wearing this protection may lead to injuries because a player is tempted to take greater risks, they say. ‘Biomechanical studies have shown a reduction in impact forces to the brain with the use of head gear and helmets, but these findings have not been translated to show a reduction in concussion incidence.’  There can also be a ‘paradoxical increase in injury rates’ when players, kitted out in protective gear, adopt more dangerous tactics.”

Researchers find sex cures migraines as well as medication

Posted on by

“Pounding headache? Sex could cure what ails you just as well as medication, a new study from the University of Munster finds.  Researchers recruited 800 migraine sufferers and 200 cluster headache sufferers. While findings are preliminary, results showed that more than half of the migraine sufferers said their pain subsided after a bout of passion with their partners. The researchers suggested that sex triggers the release of endorphins, the body’s natural painkillers, which can reduce, or even eliminate, a headache, The Telegraph reported.”

Decentralizing Science: Local Biohacking

Posted on by

“Far-out ideas make established scientists uncomfortable. If your entire career was built around the fax machine, phrenology, the geocentric model or the beeper, you’re not too excited about these crazy kids and their ideas. There is a lot of untapped brainpower out there. The state education mill is a barrier to entry, a great divider — a credential firewall. MOOCs and badges may displace the academic cartel, but not without vested interests fighting to halt creative destruction along the way.  Statistician and philosopher Nassim Nicholas Taleb recognizes that ‘stochastic tinkering’ rather than systematic, institutional agendas yield the greatest discoveries.”

Obama launches $100 million brain-mapping project

Posted on by

“US President Barack Obama on Tuesday announced a $100 million project to map the intricate inner mysteries of the human brain, targeting cures for diseases like Alzheimer’s.  The BRAIN (Brain Research through Advancing Innovative Neurotechnologies) initiative will be run by the National Institutes of Health (NIH), the Defense Advanced Research Projects Agency, and the National Science Foundation.  Obama was introduced as ‘scientist in chief’ at the White House event by NIH Director Francis Collins, and his administration makes the case that despite tough fiscal times, investments in science are vital.”

Diet soda tied to heart attack, stroke risks

Posted on by

“Diet soda may benefit the waistline, but a new study suggests that people who drink it every day have a heightened risk of heart attack and stroke.  The study, which followed almost 2,600 older adults for a decade, found that those who drank diet soda every day were 44 percent more likely than non-drinkers to suffer a heart attack or stroke.  The findings, reported in the Journal of General Internal Medicine, don’t prove that the sugar-free drinks are actually to blame.  The findings do build on a few recent studies that also found diet-soda drinkers are more likely to have certain cardiovascular risk factors, like high blood pressure or high blood sugar.”

Diet sodas linked to higher risk of Type-2 diabetes in women

Posted on by

“Artificially-sweetened sodas have been linked to a higher risk of Type 2 diabetes for women than sodas sweetened with ordinary sugar, according to French research unveiled on Thursday.  ‘Contrary to conventional thinking, the risk of diabetes is higher with ‘light’ beverages compared with ‘regular’ sweetened drinks,’ the National Institute of Health and Medical Research (Inserm) said.  The evidence comes from a wide-scale, long-term study, it said in a press release.  Sugar-sweetened sodas have previously been linked with an increased risk of diabetes, but less is known about their artificially-sweetened counterparts.”

Here Come the Salt Police!

Posted on by

“Medical researchers at Harvard University have released a report which says that Americans eat too much salt. This is a follow-up report on an earlier report by the same team, authored by the same man with the unpronounceable name, which concluded that Americans eat too much sugar.  The author of the report, predictably, called for the federal government to enact legislation to limit the intake of salt in processed foods. In other words, he wants to turn the federal government into the equivalent of Nanny Bloomberg. He doesn’t like sugar. He doesn’t like salt. And, most of all, he doesn’t like liberty.”
