Inducing therapeutic hypothermia can prevent damage from oxygen deprivation in trauma patients

Dr. Laurence Katz's emergency room patients receive a lot of different medications. Over the years, he noticed that some patients' body temperatures were dropping during treatment, due to some unknown drugs or combinations of drugs.
Inducing hypothermia can help save the lives of patients whose brains have been starved of oxygen, so Dr. Katz, an associate professor at the University of North Carolina School of Medicine, didn't want to stop the drops in body temperature -- he wanted to figure out how to chill more patients.
Last year, after several years of research, he co-founded Hibernaid, a company he hopes will use his research to make the first commercially available drug for inducing therapeutic hypothermia.
A new diagnostic test developed by researchers at ETH Zurich can tell if a patient has Type I diabetes, but gone are the days of blood samples and lab work. The new nanotech sensor can tell instantly if a patient has diabetes or an associated complication called diabetic ketoacidosis by simply analyzing a sample of exhaled breath.
New tobacco that produces flu vaccines could rescue the plant's reputation

Cigarettes kill more than four million people a year, but a cousin of the tobacco plant could help protect the rest of us from a major flu pandemic. This February, Darpa, the Pentagon's R&D branch, awarded $40 million to Texas A&M University and pharmaceutical manufacturer G-Con to launch Project GreenVax, an effort to speed vaccine production by growing it in tobacco. First, scientists engineer bacteria to carry the latest flu markers and wash them over Nicotiana benthamiana tobacco plants.
Glucose powers the cells in our bodies, and it may soon power the implantable devices we place in there as well. French researchers have implanted the first functioning glucose biofuel cell in living animals, generating electrical power from the glucose that exists naturally in the body.
Long before you even feel sick, a new Darpa-funded bio-sensor will know what ails you. Researchers at Duke University are developing a device that can betray exposure to a virus even before a person's first sneeze, Wired's DangerRoom blog reports.
The sensor detects changes in gene expression that occur in people exposed to viruses like the common cold, flu, or the respiratory syncytial virus.
Your dentist may soon be moving from needle drugs to a snort-able variety. Researchers have found that local anesthesia delivered through an inhalable nasal spray quickly travels down one of the face’s primary nerves to the mouth, which could be more effective than injecting it into the gums with a needle.
MIT researchers have made assembling artificial organs look like child's play by devising a novel approach to tissue engineering that encapsulates living cells in polymer cubes and assembles them like Lego blocks. The method, which requires no highly specialized equipment, could overcome major obstacles in artificial organ manufacture, making it possible to assemble complex 3-D structures out of living tissue cells.
A team of researchers is waging communications warfare on infectious bacteria, silencing the biochemical conversations microbes use to organize their attacks on biological tissues. By deploying plastic-like materials that soak up the chemical signals bacteria pass between one another, the team may have found a way to insert an element of confusion into the battle against antibiotic-resistant bacteria.
Walgreen's is ready to plunge headlong into the brave new world of personal genomics retailing, becoming the first retailer to stock store shelves with genetic-testing kits that can test for a person's likelihood of developing a range of genetic ailments, from Alzheimers to breast cancer to obesity. The FDA, however, isn't so thrilled.
One of the richest men in history is spreading his wealth around again. The Bill & Melinda Gates Foundation announced its fourth round of Grand Challenges Explorations grants this week, funding 78 research projects in 18 countries on six continents with $100,000 each to pursue everything from better cell phone microscopes to stronger malaria deterrents to male contraceptive techniques.
