Quantum theory reveals puzzling pattern in how people respond to some surveys Posted: 16 Jun 2014 12:13 PM PDT Researchers used quantum theory -- usually invoked to describe the actions of subatomic particles -- to identify an unexpected and strange pattern in how people respond to survey questions.

Sensor in eye could track pressure changes, monitor for glaucoma Posted: 16 Jun 2014 11:13 AM PDT Engineers have designed a low-power sensor that could be placed permanently in a person's eye to track hard-to-measure changes in eye pressure. The sensor would be embedded with an artificial lens during cataract surgery and would detect pressure changes instantaneously, then transmit the data wirelessly using radio frequency waves.

Gluten-free diet relieves 'brain fog' in patients with Celiac disease Posted: 16 Jun 2014 10:41 AM PDT Individuals with celiac disease often experience 'brain fog' in addition to intestinal problems, but a new study shows that adhering to a gluten-free diet can lead to improvements in cognition that correlate with the extent of intestinal healing. The findings indicate that ridding the diet of gluten may help address problems that celiac disease patients can experience related to attention, memory, and other mental tasks.

High-altitude weight loss may have an evolutionary advantage Posted: 16 Jun 2014 10:09 AM PDT Weight loss at high altitudes -- something universally experienced by climbers and people who move to higher terrain -- may not be a detrimental effect, but rather is likely an evolutionarily-programmed adaptation, according to a new article.

Trapping light: A long lifetime in a very small place Posted: 16 Jun 2014 10:03 AM PDT Physicists have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical cavities. An innovative design approach, which mimics evolutionary biology, allowed them to achieve a 10-fold improvement on the performance of previous nanocavities.

New project to investigate vanishing pubs in England Posted: 16 Jun 2014 06:32 AM PDT A research team aims to increase our appreciation of 'severely threatened' pubs in England. Take a walk through a typical village in England and the chances are you will stumble across a King's Head, Rose & Crown or a Red Lion for a pint of ale or a bite to eat. But how would you feel if the traditional public house were to disappear from our streets? Pubs are amongst the most common and well-loved buildings in the country, but have recently been identified as 'a severely threatened building type' by English Heritage. Researchers will take an in-depth look at the situation.

Anxious children have bigger 'fear centers' in the brain Posted: 16 Jun 2014 06:32 AM PDT The amygdala is a key "fear center" in the brain. Alterations in the development of the amygdala during childhood may have an important influence on the development of anxiety problems, reports a new study. Researchers recruited 76 children, 7 to 9 years of age, a period when anxiety-related traits and symptoms can first be reliably identified. Using non-invasive magnetic resonance imaging (MRI) scans of brain structure and function, the researchers found that children with high levels of anxiety had enlarged amygdala volume.

Smartphone apps carry higher infection risk than online dating sites or clubs Posted: 12 Jun 2014 06:25 PM PDT Phone dating apps used by gay men to find a sexual partner carry a higher risk of getting common sexually transmitted infections than meeting online or in bars and clubs, suggests research. Smartphone apps tended to be favored by younger (under 40) well educated men, and those of white or Asian ethnic backgrounds. App users were also more likely to use recreational drugs, including cocaine and ecstasy.
