Sometimes called “wear and tear” arthritis, osteoarthritis in people who are obese was long assumed to simply be a consequence of undue stress on joints. But researchers provide the first evidence that bacteria in the gut – governed by diet – could be the key driving force behind osteoarthritis.
I’m Francis Collins, Director of the National Institutes of Health. As we celebrate the 15th anniversary of the completion of the Human Genome Project, I’m here to talk about its history and the critical role it has played in precision medicine. Ask me anything!
A tooth-mounted sensor can track when patients consume glucose, salt, and alcohol. The 2-mm-by-2-mm device can then send data to smartphones and the like, according to a new study from Tufts.
By passively monitoring user-generated data from medical cannabis patients, researchers have glimpsed the types and amounts of marijuana that seem effective for relieving symptoms of stress, anxiety, and depression, as reported in the Journal of Affective Disorders.
Researchers have characterized a complex, little-understood receptor type that, when activated, shuts off hunger. The findings may open up opportunities to fight obesity at the cellular level.
Researchers discover Autistic children inherit rare damaging noncoding variants from fathers but not mothers
A rare mutation among the Bajau people lets them stay underwater longer: natural selection at the PDE10A gene has increased spleen size in the Bajau, providing them with a larger reservoir of oxygenated red blood cells.

A macque study finds a potential non-hormonal, fully reversible, and short-lived pharmacological male contraceptive that works through inhibition of sperm motility
A common belief is that good-looking people also earn more money. But a new study turns this theory on its head. Researchers have found that people who are "very unattractive" may be the biggest earners, based on data from a study of 20,000 young Americans.

Acupuncture eases drug addiction withdrawal symptoms by activating peripheral nervous system, which stimulates neurons that restore dopamine levels.
Scores of plant species are capable of living dormant under the soil for up to 20 years, enabling them to survive through difficult times
An unprecedented wave of large-mammal extinctions is linked to prehistoric humans. Homo sapiens, Neanderthals and other recent human relatives hunted large mammal species to extinction. The magnitude and scale of the extinction wave surpasses any other recorded during the last 66 million years.

Study: GMO Food Labels Could Burden Low-Income Consumers
New drug uses antibodies to stop chronic migraines by blocking the neural pathway that sends pain signals to the brain during a migraine. Phase III trials on about 1,000 subjects are complete now and there are already plans for it to be approved by the FDA.
Due to climate change the niche of giant trees is projected to increase by ~4 million km2 globally - "Our results imply that strategic management could in principle facilitate the expansion of giant forests, securing critically endangered biodiversity as well as carbon storage."
New microscope creates 3D movies of cells in living organisms. "It's like Star Trek" say Harvard researchers.

Scientists Discover How to Bend and Stretch Diamonds—the Hardest Natural Material
Oil spills could be soaked up by a new floating substance that combines waste from the petroleum industry and cooking oil. The new polymer acted like a sponge to remove crude oil and diesel from seawater. The polymer can be squeezed to remove the oil and then reused.
Superionic ice has been created in the lab for the first time. The ultra-conductive version of ice, which accounts for 60% of Uranus and Neptune, was formed by compressing ice to 25,000 times the atmospheric pressure felt at sea level. The resulting ice was sixty times denser than regular water.
Cold Temp Exposure Causes Epigenetic Changes in Fat Cells
Researchers found that simply being told that a performer is a professional or a student changes the way the brain responds to music. They also found that overcoming this bias took a deliberate effort.
Americans waste 150,000 tons of food each day – equal to a pound per person. USDA research shows people with healthy diets rich in fruit and vegetables are the most wasteful.
Male fruit flies enjoy ejaculation. Fly brains showed increased signs of a rewarding experience after ejaculating, even with no females present.
In an example of recent human evolution, scientists find free divers from Southeast Asia evolved bigger spleens, thought to give them greater endurance when holding their breaths.
