MOOC providers currently offer thousands of courses and have enticed millions of students to enroll. The emphasis in MOOCs is often on lecture videos that students watch and learn from. However, a new study shows that this central approach of MOOCs -- having students watch to learn -- is…

More than a billion times a year, American hospital patients get tiny tubes inserted into their veins to deliver medicine and more. But these devices carry risks as well as benefits -- especially those designed to stay in the body for days or weeks. A newly published, research-based guide shows…

Humans are extremely choosy when it comes to mating, only settling down after a long screening process involving nervous flirtations, awkward dates, humiliating rejections and the occasional lucky strike. But evolution is an unforgiving force -- isn't this choosiness rather a costly waste of time…

A new review has produced the most conclusive evidence to date that people consume more food or non-alcoholic drinks when offered larger sized portions or when they use larger items of tableware. The research suggests that eliminating larger-sized portions from the diet completely could reduce…

Bacteria aren't the only nonhuman invaders to colonize the gut shortly after a baby's birth. Viruses also set up house there, according to new research. The study is one of the first surveys of viruses that reside in the intestine, beginning the work of defining a healthy gut virome.

Microbiology researchers studying a soil bacterium have identified a potential mechanism for neurodegenerative diseases. A role for the protein HSD10 had been suspected in patients with Alzheimer's disease and Parkinson's disease, but no direct connection had previously been established. This new…

Three antibiotics that, individually, are not effective against a drug-resistant staph infection can kill the deadly pathogen when combined as a trio, according to researchers. They have killed the bug -- methicillin-resistant Staphylococcus aureus -- in test tubes and laboratory mice, and believe…

A new protocol to treat babies born in withdrawal from drugs can be used widely to improve outcomes for these babies. The protocol reduces length of stay and the duration of treatment with opioids that are used therapeutically to wean babies off of drugs.

One in four middle-aged adults who survive to age 85 will develop heart failure, according to current estimates. Intervention programs to improve lifestyles are widely advocated, but do they actually work? Investigators in the US and Taiwan independently examined programs that may reduce…

A new technique for creating transparent tissue has been developed that can be used to illuminate 3-D brain anatomy at very high resolutions. In recent years, generating see-through tissue--a process called optical clearing--has become a goal for many researchers in life sciences because of its…

Rare genetic variants are changes in DNA that are carried only by relatively few people in a population. The UK10K study was designed to explore the contribution of these rare genetic variants to human disease and its risk factors. The largest population genome sequencing effort to date has been…

Black children were less likely to receive any pain medication for moderate pain and less likely to receive opioids for severe pain than white children in a study of racial disparities in the pain management of children with appendicitis in emergency departments, according to an article.

A new technique to recondition poorly functioning lungs and remove donor white blood cells has been used by researchers in an attempt to increase the number of lungs available for transplant, and at the same time reduce the risk of acute rejection.

The next time someone accuses you of making an irrational decision, just explain that you're obeying the laws of quantum physics. A new trend taking shape in psychological science not only uses quantum physics to explain humans' (sometimes) paradoxical thinking, but may also help researchers…

Two research teams have just shown, in a rodent model, that overexpressing an enzyme that can eliminate excess cholesterol from the brain may have a beneficial action on the tau component of the disease, and completely correct it.
