A small but growing number of science and math teachers aren't spending the summer at the beach or catching up on books, they're toiling at companies, practicing the principles they teach. As American education focuses on closing the gap between the classroom and employers' needs, programs in North Carolina, California and elsewhere are putting teachers temporarily in the workplace.

Using data from over 18,000 patients, scientists have identified more than two dozen genetic risk factors involved in Parkinson's disease, including six that had not been previously reported.
Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say. A fresh study using up-to-date fossil records and improved analytical tools has helped palaeontologists to build a new narrative of the prehistoric creatures' demise, some 66 million years ago.
In the first broad-scale estimate of air pollution removal by trees nationwide, U.S. Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidences of acute respiratory symptoms.
A study involving nearly 27,000 older adults on five continents found that nearly 1 in 10 met criteria for pre-dementia based on a simple test that measures how fast people walk and whether they have cognitive complaints. People who tested positive for pre-dementia were twice as likely as others to develop dementia within 12 years.
Researchers are exploring ways to wake up the immune system so it recognizes and attacks invading cancer cells. Tumors protect themselves by tricking the immune system into accepting everything as normal, even while cancer cells are dividing and spreading. One pioneering approach uses nanoparticles to jumpstart the body's ability to fight tumors.
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug. The study is the first to show that melatonin is vital to the success of tamoxifen in treating breast cancer.
The European Society for Medical Oncology (ESMO) has expressed concern that the proposed EU General Data Protection Regulation could make cancer research impossible and add a significant burden to both doctors and cancer patients.
The U.S. Food and Drug Administration isn't required to hold public hearings to evaluate the health risks of widespread use of antibiotics in animal feed, a federal appeals court ruled Thursday. The decision by the 2nd U.S. Circuit Court of Appeals reversed a ruling in 2012 by a district court that sided with several health and consumer organizations that sued the FDA after the agency decided against holding the hearings.
For the first time ever, researchers have created a biodegradable biomaterial that is inherently antioxidant. The material can be used to create elastomers, liquids that turn into gels, or solids for building devices that are more compatible with cells and tissues.
Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery is also relevant for other infectious diseases including bacterial infections and tuberculosis.
Only 8.2 percent of human DNA is likely to be doing something important, or is “functional.” This figure is very different from one given in 2012, when some scientists involved in the ENCODE project stated that 80 percent of our genome has some biochemical function.
Parts of the primordial soup in which life arose have been maintained in our cells today. Research reveals how cells in plants, yeast and very likely also in animals still perform ancient reactions thought to have been responsible for the origin of life- some four billion years ago.
Could the body's own immune system play a role in memory impairment and cognitive dysfunction associated with conditions like chronic epilepsy, Alzheimer's, dementia and concussions? According to a new study, yes.
Repeated freezing and thawing might not be good for the average steak, but each fall it might help wood frogs prepare to survive Alaska’s winter cold. Frogs prevent the freeze-pop effect by packing their cells with glucose, a kind of sugar that reduces drying and stabilizes cells, a process scientists call cryoprotection.
Breaking the mold of inherited family characteristics could help you survive in a fast-changing world, scientists have discovered. A new study has shown that such slowly changing genes are only beneficial in a steady environment.
Fragile X syndrome (FXS) is a genetic disorder that causes obsessive-compulsive and repetitive behaviors, and other behaviors on the autistic spectrum, as well as cognitive deficits. It is the most common inherited cause of mental impairment and the most common cause of autism. Now, biomedical scientists have published a study that sheds light on the cause of these behaviors.
Intestinal parasites such as tapeworms, hookworms and a protist called Blastocystis can be beneficial to human health, according to a new paper that argues we should rethink our views of organisms that live off the human body.
According to the World Health Organization, 3.4 million people die from water-related diseases every year. A research team spent a year researching a membrane filter and developing a prototype. What makes the DrinkPure filter unique is that you can screw it on to virtually any plastic bottle. It doesn't require a pump or a reservoir.
Medicine focuses almost entirely on fighting chronic diseases in a piecemeal fashion as symptoms develop. Instead, more efforts should be directed to promoting interventions that have the potential to prevent multiple chronic diseases and extend healthy lifespans.
The head of the government lab that potentially exposed workers to live anthrax has resigned. Michael Farrell was head of the Centers for Disease Control and Prevention lab since 2009. He submitted his resignation Tuesday.
The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication. Scientists found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.
Scientists at Brigham and Women’s Hospital have developed a scalable, next-generation platelet bioreactor to generate fully functional human platelets in vitro. The work might help address blood transfusion needs worldwide.
Controlling pain during childbirth and post delivery may reduce the risk of postpartum depression. Findings are based on a new Chinese study that found women who had pain control with epidural anesthesia during a vaginal delivery had a much lower risk for postpartum depression than women who didn't have the epidural.
If you’re allergic to dust mites (and chances are you are), help may be on the way. Researchers have developed a vaccine that can combat dust-mite allergies by naturally switching the body’s immune response. In animal tests, the nano-sized vaccine package lowered lung inflammation by 83 percent despite repeated exposure to the allergens.
A probiotic that prevents obesity could be on the horizon. Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice.
