Cell phone use has become a common part of life as mobile devices have become one of the most popular ways to communicate. Even so, very little research exists on the impact of cell phone usage and specifically what happens when people are separated from their phones. Now, research has found that cell phone separation can have serious psychological and physiological effects on iPhone users, including poor performance on cognitive tests.

Those who work night shifts are significantly more likely to develop diabetes than those who have never worked night shifts, with more years working the night shift resulting in a higher risk. These are the results from a large ongoing study into the health of African-American women. Furthermore, the increased risk of diabetes seen in shift workers was more pronounced in younger women than older women, researchers say.

A study has defined allergen levels in food that can trigger allergic reactions which will help to make allergen warning labels more effective. "What we wanted was to find a level of allergen which would only produce a reaction in the most sensitive ten percent of people. This sort of data can then be used to apply a consistent level of warning to food products," the lead author said.

A novel molecular mechanism that tightens the bonds between the cells that line blood vessels to form a leak-proof barrier has been discovered by researchers. The mechanism presents a potential new target to treat acute respiratory distress syndrome, an often fatal condition in which fluid leaks out of blood vessels into the lungs.

In 1961, with memories of Holocaust atrocities and the prosecution of Nazi officials at Nuremburg still fresh, psychologist Stanley Milgram undertook a series of now infamous experiments on obedience and reprehensible behavior. But Milgram divided his subjects into just two categories: obedient or disobedient. After examining the experiences of more than 100 of Milgram's participants, a modern day graduate student in sociology sees a great deal more nuance in their performances.

After a forest fire, logging companies often follow to do what is called salvage logging--salvaging the timber that has not been completely destroyed by the fire. The economic benefit is clear. But the ecological effects are unknown, experts say.

Plans for the construction of the world's largest digital camera at the Department of Energy's SLAC National Accelerator Laboratory have reached a major milestone. The 3,200-megapixel centerpiece of the Large Synoptic Survey Telescope (LSST), which will provide unprecedented details of the universe and help address some of its biggest mysteries, has received key "Critical Decision 2" approval from the DOE.

The "warming hiatus" that has occurred over the last 15 years has been caused in part by small volcanic eruptions. Scientists have long known that volcanoes cool the atmosphere because of the sulfur dioxide that is expelled during eruptions. Droplets of sulfuric acid that form when the gas combines with oxygen in the upper atmosphere can persist for many months, reflecting sunlight away from Earth and lowering temperatures at the surface and in the lower atmosphere. New research further identifies observational climate signals caused by recent volcanic activity.

Adding head and neck cancer screenings to newly recommended lung cancer screenings would likely improve early detection and survival, according to a multidisciplinary team led by scientists. Head and neck cancer is the world's sixth-most common type of cancer. Worldwide every year, 600,000 people are diagnosed with it and about 350,000 die. Tobacco use and alcohol consumption are the major risk factors for developing the cancer.

For patients with spinal stenosis, long-term outcomes are comparable with surgery or conservative treatment, reports a new study. While earlier reports suggested an advantage of surgery, the updated analysis finds no significant difference in pain, functioning, of disability at eight years' follow-up.

Karyomapping has been identified as a viable and cost-effective method of detecting a wide range of genetic diseases in IVF embryos, scientists report. The current method, which involves the use of preimplantation genetic diagnosis (PGD) for monogenic disorders (resulting from a single defective gene) has long been recognized as expensive, time-consuming and requires the tailoring of a specific test for each couple and/or disorder.

Upon evaluating the new fixed-dose combination of dolutegravir/abacavir/lamivudine for adolescents and pretreated adults with HIV, added benefit is not proven because suitable data are lacking. However, there is an indication that adults who have not been treated for their HIV infection have considerable added benefit from treatment with the new fixed-dose combination.

Among patients with a kidney disease called focal segmental glomerulosclerosis (FSGS), those who had certain genetic variants tended to have more advanced disease when they were diagnosed, researchers report. Patients with the variants responded to immunosuppressant treatments just as well as other patients but tended to progress more rapidly to kidney failure.
