How smells stick to your memories: Your nose can be a pathfinder Posted: 16 Apr 2014 10:33 AM PDT Waves in your brain make smells stick to your memories and inner maps. Researchers have recently discovered the process behind this phenomenon. The brain, it turns out, connects smells to memories through an associative process where neural networks are linked through synchronized brain waves of 20-40 Hz.

Percent of uninsured Texans declined since September 2013 Posted: 16 Apr 2014 09:56 AM PDT The percentage of uninsured adults ages 18 to 64 in Texas declined from 24.8 to 23.5 between September 2013 and March 2014, according to a report. The decrease in uninsured appears to be attributable to an increase in employer-sponsored health insurance. The report also found that during this period approximately 746,000 Texans purchased health insurance through the Affordable Care Act's Health Insurance Marketplace, of which 178,000 (30.2 percent) were previously uninsured.

Multiple births don't have to be an inevitable result of fertility treatments Posted: 16 Apr 2014 07:16 AM PDT While fertility treatments have helped many people become parents, they commonly result in multiple births, increasing the risk of prematurity, and leading to lifelong complications. But this doesn't have to be the case, according researchers, who recommend sweeping changes to policy and clinical practice.

How toddlers learn verbs: New insight Posted: 16 Apr 2014 07:16 AM PDT Parents can help toddlers' language skills by showing them a variety of examples of different actions, according to new research. Previous research has shown that verbs pose particular difficulties to toddlers as they refer to actions rather than objects, and actions are often different each time a child sees them.

Computer software analyzing facial expressions accurately predicts student test performance Posted: 16 Apr 2014 07:13 AM PDT Real-time engagement detection technology that processes facial expressions can perform with accuracy comparable to that of human observers, according to new research. The study used automatic expression recognition technology to analyze students' facial expressions on a frame-by-frame basis and estimate their engagement level. The study also revealed that engagement levels were a better predictor of students' post-test performance than the students' pre-test scores.

Body mass index associated with breast cancer, regardless of body shape Posted: 16 Apr 2014 06:08 AM PDT A larger waist circumference is associated with higher risk of postmenopausal breast cancer, but not beyond its contribution to BMI, a new study of predominantly white women finds. The study fails to confirm previous findings that body shape itself is an independent risk factor for breast cancer.

Masculine boys, feminine girls more likely to engage in cancer risk behaviors, study finds Posted: 16 Apr 2014 06:03 AM PDT The most "feminine" girls and "masculine" boys are more likely than their peers to engage in behaviors that pose cancer risks, according to a new study. The most feminine teenage girls use tanning beds more frequently and are more likely to be physically inactive, while the most masculine teenage boys are more likely to use chewing tobacco and to smoke cigars, compared with their gender-nonconforming peers.

Vitamin D deficiency contributes to poor mobility among severely obese people Posted: 15 Apr 2014 10:38 AM PDT Among severely obese people, vitamin D may make the difference between an active and a more sedentary lifestyle, according to a new study. The study found severely obese people who also were vitamin D-deficient walked slower and were less active overall than their counterparts who had healthy vitamin D levels. Poor physical functioning can reduce quality of life and even shorten lifespans.
