Credit score can also describe health status

A new analysis from a long-term study of over 1,000 New Zealanders found a strong relationship between low credit scores and poor cardiovascular health. The study also suggests that personal attributes such as self-control, planning ahead, and perseverance can predict both better financial status and better health.

With rewards, we remember more than we should

A new study at Brown University found that reward overcomes retrieval-induced forgetting, a phenomenon where practicing certain facts suppresses recall of others. Volunteers who earned rewards during practice had improved recall of unpracticed fish category facts.

A noncoding RNA promotes pediatric bone cancer

A new study identifies Ewing sarcoma-associated transcript 1 (EWSAT1) as a critical target of the EWS-FLI1 fusion protein, contributing to cancer cell growth and repression of key genes. This finding supports the notion that long noncoding RNAs can drive cancer development and highlights an important mediator in Ewing Sarcoma.

Infection-fighting B cells go with the flow

B cells use a unique migration strategy in the bone marrow that allows them to exit slowly and be passively swept out by blood flow. The researchers found that the absence of CXCR4 significantly slows down B cell movement, highlighting the importance of this protein in regulating immune cell egress.

High mortality associated with STEMI heart attacks that occur in hospitalized patients

A new study published in JAMA found that hospitalized patients with STEMI heart attacks are more likely to die than those who had the same type of heart attack outside the hospital. The study analyzed data from over 62,000 patients and found that these patients were older, female, and less likely to receive routine treatments for STEMI.

Spiral laser beam creates quantum whirlpool

Physicists at Australian National University have created a spiral laser beam that generates a stable vortex of polaritons, which are hybrid particles exhibiting both matter-like and light-like behavior. This achievement could enable the development of novel technology linking conventional electronics with photonics.

80 million bacteria sealed with a kiss

Researchers found that couples who kiss frequently share similar oral bacteria, with at least nine kisses per day leading to significantly shared salivary microbiota. The study also suggests an important role for other mechanisms that select oral microbiota, shaped by lifestyle and personal care habits.

Study finds weight loss of 10 percent or more in seniors significantly raises hip fracture risk

A new study has found that weight loss of 10 percent or more in seniors substantially increases the risk of hip fractures. The Singapore Chinese Health Study found that body weight changes were associated with a significant increase in hip fracture risk, whereas weight gain did not reduce risk significantly.

Resuscitation science tip sheet

Research presented at the American Heart Association's Scientific Sessions 2014 found that implementing pre-arrival telephone CPR guidelines in Arizona increased bystander CPR rates by 41% and survival rates by 42%. The study also showed that women are more likely to survive sudden cardiac arrest compared to men.
