Blood stem cell transplantation, widely known as bone marrow transplantation, is a powerful technique that potentially can provide a lifelong cure for a variety of diseases. But the procedure is so toxic that it is currently used to treat only the most critical cases.

Now, researchers at the Stanford University School of Medicine have come up with a way of conducting the therapy that, in mice, dramatically lowers its toxicity. If the method eventually proves safe and effective for humans, it potentially could be used to cure autoimmune diseases like lupus, juvenile diabetes and multiple sclerosis; fix congenital metabolic disorders like "bubble boy" disease; and treat many more kinds of cancer, as well as make organ transplants safer and more successful.

 By assessing electronic medical records (EMR) of 32,835 unique individuals from six Dallas-Fort Worth area hospitals, and noting abnormalities in temperature, heart rate, blood pressure, respiratory rate, and oxygen saturation within 24 hours of discharge, scholars determined that nearly 20 percent had one or more abnormalities, with elevated heart rate being the most common vital sign instability (affecting about 10 percent.) About 13 percent were readmitted or died, and individuals with three or more instabilities had a nearly four-fold increase in the odds of death.  

How to be a healthy eater depends on culture. A recent study shows that in the U.S. and Japan, people who fit better with their culture have healthier eating habits. The results appear in Personality and Social Psychology Bulletin.

"Our results suggest that if you want to help people to eat healthier--or if you want to promote any type of healthy behavior--you want to understand what meaning that behavior has in that culture, and what motivates people to be healthy in that culture," says lead author Cynthia Levine.

Healthy eating can help reduce one's risk for a number of different diseases down the line, including heart disease, type 2 diabetes, and certain types of cancer.

The Piltdown Man scandal is arguably the greatest scientific fraud ever perpetrated in the UK, with fake fossils being claimed as evidence of our earliest ancestor.

Published 100 years on from Dawson's death, new research reveals that the forgeries were created using a limited number of specimens that were all constructed using a consistent method, suggesting the perpetrator acted alone.

It is highly likely that an orang-utan specimen and at least two human skeletons were used to create the fakes, which are still kept at the Natural History Museum.

Health researchers predict that the transmission of dengue could actually decrease in a warmer climate, countering previous apocalyptic cocktail projections which included that the lethal virus would spread more easily.

Hundreds of millions of people are already infected with dengue each year, with some children dying in severe cases, so increasing a significant global health problem is an alarming concern. The model instead finds that a warmer climate would mean the ecologically useless mosquitoes that carry Dengue (and also Zika) would die off in the drier sections of the wet tropics of northeast Australia.

For years scientists and dieticians have argued over the health benefits of dietary fat. Research published this week, however, shows that piggybacking onto natural fat absorption pathways can dramatically enhance the utility of some drugs.

One of the key goals of drug development has long been to produce a therapy that can be taken orally (therefore cheap and easy to deliver) and is absorbed as directly and quickly into the blood stream as possible.

Many medications, however, are broken down in the liver before even making it into the blood stream. This is called "first past metabolism" whereby the drugs we swallow go via the gut and the liver (where breakdown occurs) before even entering the blood.
