Firing of neurons changes the cells that insulate them

Through their pattern of firing, neurons influence the behavior of the cells that upon maturation will provide insulation of neuronal axons, according to a new study. The findings suggest the existence of a complex and nuanced interplay between neurons and the non-neuronal cells that support and protect them.

Brown dwarf weather forecasts improved

Dim objects called brown dwarfs, less massive than the Sun but more massive than Jupiter, have powerful winds and clouds -- specifically, hot patchy clouds made of iron droplets and silicate dust. Scientists recently realized these giant clouds can move and thicken or thin surprisingly rapidly, in less than an Earth day, but did not understand why.

When given the chance to pay less, patients choose cheaper prescription drugs

When given the chance to pay less, patients choose cheaper prescription drugs

As prescription drug spending continues to rise in the United States, along with prices for new and well-established drugs, insurers, employers and patients are searching for ways to cut costs. A new study found that a policy called reference pricing is effective at encouraging patients to spend significantly less on prescription drugs by choosing cheaper drugs over name brand options.

Yoga and meditation improve mind-body health and stress resilience

A new research article investigates the effects of yoga and meditation on people by looking at physiological and immunological markers of stress and inflammation. By studying the participants of an intensive three-month yoga and meditation retreat, the researchers found that the practices positively impacted physiological and immunological markers of stress and inflammation, and in addition improved subjective wellbeing.

You may be as friendly as your genes

Scientists have found that CD38 and CD157 genes that regulate oxytocin, the supreme human social hormone, are associated with the sociality of young individuals. They found that young adults who have higher expression of the CD38 gene as well as differences in CD157 gene sequence are friendlier and more socially adept than others. They have more close friends and show greater social skills.

Schools need to encourage broader participation in science learning outside of the classroom

Schools are failing to offer sufficient opportunities for students from diverse backgrounds to engage in science-based learning outside of the classroom, and should be doing more to open up participation, according to new research.

Postnatal identification of Zika virus peptides from saliva

For the first time, researchers are using proteomics to examine proteins and peptides in saliva in order to accurately detect exposure to Zika virus. With 70 countries and territories reporting evidence of mosquito-borne Zika virus transmission, there is an increased need for a rapid and effective test for the virus. This study offers a new, quicker and more cost-effective way to test for the virus.

Dino-killing asteroid could have thrust Earth into two years of darkness

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs.

Antarctic salt-loving microbes provide insights into evolution of viruses

Scientists studying microbes from some of the saltiest lakes in Antarctica have discovered a new way the microbes can share DNA that could help them grow and survive. The research, based on 18 months of water sampling in remote Antarctic locations, could throw light on the evolutionary history of viruses. The team discovered some of the microbes contained small molecules of DNA called plasmids.
