And the prototype is surprisingly simple – a mobile phone attached to a hip belt that can be programmed and connected to a fall algorithm. The hip belt is attached to the person requiring the alarm, and the alarm is triggered automatically as soon as the wearer takes a fall.

Teens close to high number of tobacco shops more likely to smoke Posted: 05 Nov 2014 05:35 PM PST Teenagers are much more likely to take up smoking if they live in neighborhoods with a large number of shops that sell tobacco products, a study suggests. Adolescents with the most tobacco outlets in their neighborhood are almost 50% more likely to smoke than those with no outlets nearby, researchers say.

Antibiotics: On-the-spot tests reduce unnecessary prescriptions Posted: 05 Nov 2014 05:35 PM PST Fast, on-the-spot tests for bacterial infections may help to reduce excessive antibiotic use. A systematic review found that when doctors tested for the presence of bacterial infections they prescribed fewer antibiotics.

CT lung screening appears cost-effective Posted: 05 Nov 2014 05:35 PM PST In 2010 the National Lung Screening Trial showed that screening for cancer with low-dose CT scans could reduce mortality by 20 percent compared to using chest X-rays.

Ah-choo! Expect higher grass pollen, allergen exposure in coming century Posted: 05 Nov 2014 12:45 PM PST There will be notable increases in grass pollen production and allergen exposure up to 202 percent in the next 100 years, leading to a significant, worldwide impact on human health due to predicted rises in carbon dioxide and ozone due to climate change. This is the conclusion of researchers who say that while CO2 stimulates reproduction and growth in plants, ozone has a negative impact on plant growth.

ADHD-air pollution link: Breathing dirty air during pregnancy raises odds of childhood ADHD-related behavior problems Posted: 05 Nov 2014 12:45 PM PST Prenatal exposure to polycyclic aromatic hydrocarbons, or PAH, a component of air pollution, raises the odds of behavior problems associated with attention deficit hyperactivity disorder, or ADHD, at age 9, according to researchers.

Direct brain interface between humans Posted: 05 Nov 2014 12:45 PM PST Researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team's initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person's brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.

Pediatricians' communication with parents critical to overcoming obesity in Latino children Posted: 05 Nov 2014 12:45 PM PST Physician-researchers found that 1-in-5 parents of overweight Latino children is not directly told that the child is overweight. "Special attention should be paid to directly telling Latino families that the child is overweight using family-preferred terms," said researchers. "For example, pediatricians should use phrases such as 'too much weight for his/her health' or 'demasiado peso para su salud,' and avoid terms such as 'fat,' 'heavy,' or 'obese.' "

Expansion of gambling does not lead to more problem gamblers, study finds Posted: 05 Nov 2014 12:45 PM PST In the past decade, online gambling has exploded and several states have approved measures to legalize various types of gambling.
