After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
If you are insecure or craving attention and need to feel better about yourself, chances are Facebook is your friend, according to surveys done by psychologists.According to analysis of two surveys of nearly 600 people ages 18-83, people who are generally insecure in their relationships are more actively engaged on the social media site. They are frequently posting on walls, commenting, updating their status or "liking" something in hopes of getting attention. That leads the psychologists to conclude there are two kinds of insecure people who rely on Facebook: people who are higher in attachment anxiety and people who are higher in extraversion.
Because Americans spend more per capita on health care than residents of any country, debate has rumbled on for years about whether all that investment yields sufficient results. Now a newly published study with a distinctive design, led by an MIT health care scholar, shows that increased spending on emergency care does, in fact, produce better outcomes for patients.
"If the question is, 'Do high-spending hospitals get better outcomes for emergency care?' -- we think that they do," says MIT economist Joseph Doyle. "We do find that if you go from a low-spending hospital to a high-spending hospital, you get significantly lower mortality rates."
With Valentine's Day this weekend, we will be treated to articles called things 'the science of kissing', 'the science of love', 'the science of attraction' - you name it and someone in the social sciences is capitalizing on the fuzzy nature of romance to attract some eyeballs. Love at first sight has long been discussed but is there love at first smell? Can you get love in a spray bottle? Kate Upton is going to be around a lot of smelly men this week, if so.

Middle-school children who consume energy drinks are 66% more likely to be at risk for hyperactivity and inattention symptoms, according to results from the Yale School of Public Health, which could have implications for school success and lends support to existing recommendations to limit the amount of sweetened beverages schoolchildren drink. The authors,
led by professor Jeannette Ickovics, director of Community Alliance for Research and Engagement, recommend that children avoid energy drinks because of high levels of sugar and caffeine.
Skin provides an essential protective barrier against foreign materials and pathogens and helps the body retain various fluids and electrolytes. When that barrier is damaged, the consequences can be devastating. Ulcers, bleeding and bacterial infections may result and the chances of these occurring increases the longer wounds remain open. Fortunately, epithelial cell sheets are self-repairing. The moment the integrity of the barrier is compromised, cellular mechanisms are initiated to close the gap. Cells begin crawling forward, and contractile cables are formed in the cells surrounding the wound to help pull the gap closed.
A recent finding about capsaicin from chili peppers curbing obesity in mice may be why nutritionists and diet marketing groups latch onto it in 2015. The world doesn't need another gimmick diet but clearly people need to eat less. Fully one third of the world is overweight, by World Health Organization estimates. Now a group at the University of Wyoming has found promise in the potential of capsaicin -- the chief ingredient in chili peppers -- as a diet-based supplement.
Small magnetic whirls may revolutionize future data storage and information processing if they can be moved rapidly and reliably in small structures. A team of scientists of Johannes Gutenberg University Mainz (JGU) and TU Berlin, together with colleagues from the Netherlands and Switzerland, has now been able to investigate the dynamics of these whirls experimentally. The skyrmions, as these tiny whirls are called after the British nuclear physicist Tony Skyrme, follow a complex trajectory and even continue to move after the external excitation is switched off. This effect will be especially important when one wants to move a skyrmion to a selected position as necessary in a future memory device.
Kalorama Information expects the market for plasma collection to grow, and to outpace overall blood collection through 2018. The primary market driver will be plasma-derived immunoglobulins (Ig) used to produce intravenous immunoglobulin (IVIG) therapies. The growth of mature markets associated with the collection, processing and therapeutic use of whole blood and derived products are by and large endangered without the robustness of the global plasma market. This is the finding of Kalorama Information's recent Blood: The Worldwide Market for Blood Products, Blood Testing, Blood Equipment, and Synthetic Blood Products.
A new study has shown an unprecedented degree of connectivity reorganization in newly-generated hippocampal neurons in response to experience, suggesting their direct contribution to the processing of complex information in the adult brain.The hippocampus is an anatomical area of the brain classically involved in memory formation and modulation of emotional behavior. It is also one of the very few regions in the adult brain where resident neural stem cells generate new neurons life-long, thus providing the hippocampal circuitry with an almost unique renewal mechanism important for information processing and mood regulation.
Bariatric surgery improves life expectancy for many obese diabetic patients, but it may cut life expectancy for patients who are super obese with very high body mass indexes, according to a University of Cincinnati researcher.
"For most patients with diabetes and a BMI (body mass index) greater than 35, bariatric surgery increases life expectancy," says Daniel Schauer, MD, assistant professor in the Division of General Internal Medicine at UC. "However, the benefit of surgery decreases as BMI increases. The patients with a BMI over 62 likely don't gain any life expectancy with surgery."
The findings were published recently online in the Annals of Surgery.
Resveratrol found in common foods such as red grapes and peanuts may help prevent age-related decline in memory, according to a new paper.
Ashok K. Shetty, Ph.D., a professor in the Department of Molecular and Cellular Medicine and Director of Neurosciences at the Institute for Regenerative Medicine, has been studying the potential benefits of resveratrol, a controversial antioxidant that is found in the skin of red grapes, as well as in red wine, peanuts and some berries. Resveratrol has been promoted for its potential to prevent heart disease, but Shetty and colleagues believe it also has positive effects on the hippocampus, an area of the brain that is critical to functions such as memory, learning and mood.
