New reprogramming method makes better stem cells

New reprogramming method makes better stem cells

A team of researchers from the University of California, San Diego School of Medicine, Oregon Health & Science University (OHSU) and Salk Institute for Biological Studies has shown for the first time that stem cells created using different methods produce differing cells. The findings, published in the July 2, 2014 online issue of Nature , provide new insights into the basic biology of stem cells and could ultimately lead to improved stem cell therapies.

Causes of serious pain syndrome closer to discovery

Causes of serious pain syndrome closer to discovery

Researchers at the University of Liverpool have taken a major step forward in understanding the causes of a disorder which causes chronic pain in sufferers. Complex Regional Pain Syndrome (CRPS) is a serious condition affecting a limb after an — often small — accident or operation. It can cause severe pain lasting many years, as well as limb swelling, hair and nail growth changes, and muscle atrophy, but until now there has been no clear evidence of the cause Continue reading

Twin study links community socioeconomic deprivation to sleep duration

Twin study links community socioeconomic deprivation to sleep duration

A new study of adult twins suggests that the level of socioeconomic deprivation in a neighborhood is associated with the sleep duration of residents. Results show that increased socioeconomic deprivation was significantly associated with decreased sleep duration across all twins. Continue reading

Fruit fly research may reveal what happens in female brains during courtship, mating

Fruit fly research may reveal what happens in female brains during courtship, mating

What are the complex processes in the brain involved with choosing a mate, and are these processes different in females versus males? It’s difficult to study such questions in people, but researchers are finding clues in fruit flies that might be relevant to humans and other animals. Continue reading

Nearly 80 percent of US deaths in first three decades of life are due to unintentional injury or violence

Nearly 80 percent of US deaths in first three decades of life are due to unintentional injury or violence

A new report on unintentional injury and violence in the United States, published in The Lancet as part of a new Series, The health of Americans, has found that prevention strategies across society show a great deal of promise in preventing unintended deaths and injuries. According to the report, by CDC researchers from Atlanta, USA, more Americans between the ages of one and 30 die from injury than from any other cause. Every year, nearly 180,000 people in the USA die from preventable causes such as automobile crashes, drowning, firearm-related injuries, falls, assault, and drug overdoses; equivalent to one injury death every 3 minutes Continue reading

Seeing your true colors: Standards for hyperspectral imaging

Seeing your true colors: Standards for hyperspectral imaging

Today, doctors who really want to see if a wound is healing have to do a biopsy or some other invasive technique that, besides injuring an already injured patient, can really only offer information about a small area. But a technology called hyperspectral imaging offers doctors a noninvasive, painless way to discriminate between healthy and diseased tissue and reveal how well damaged tissue is healing over a wide area. The catch Continue reading
