Brain inflammation linked to depression in multiple sclerosis2

Patients with multiple sclerosis have higher rates of depression than the general population, including people with other life-long disabling diseases. Symptoms of multiple sclerosis arise from an abnormal response of the body's immune system. Immune response has also been linked to depression, leading researchers to think it could be a shared pathological mechanism that leads to the increased rates of depressive symptoms in patients with multiple sclerosis.

Astronomers find evidence for ‘direct collapse’ black hole1

Astronomers have discovered evidence for an unusual kind of black hole born extremely early in the universe. They showed that a recently discovered unusual source of intense radiation is likely powered by a "direct-collapse black hole," a type of object predicted by theorists more than a decade ago.

Children who watch lots of TV may have poor bone health later in life2

Consistently watching high levels of television during childhood and adolescence were linked with lower peak bone mass at age 20 years in a recent study. Hours of television watching per week were recorded by parental or self-report at 5, 8, 10, 14, 17 and 20 years of age in 1181 participants. Those who consistently watched ?14 hours/week of television had lower bone mineral content than those who watched less television, even after adjusting for height, body mass, physical activity, calcium intake, vitamin D levels, alcohol, and smoking (all at age 20).

Earth-size telescope tracks the aftermath of a star being swallowed by a supermassive black hole1

Radio astronomers have used a radio telescope network the size of the Earth to zoom in on a unique phenomenon in a distant galaxy: a jet activated by a star being consumed by a supermassive black hole. The record-sharp observations reveal a compact and surprisingly slowly moving source of radio waves.

Benefits from freeze-all embryo strategy in older IVF patients2

Conventional IVF protocols involve the transfer of a fresh embryo to the uterus during the same cycle in which the eggs were collected and freezing extra embryos for future use. A novel approach to improving IVF outcomes has recently emerged in which all embryos generated from an egg collection cycle are electively frozen and transferred in a subsequent cycle.

Small molecule keeps new adult neurons from straying, may be tied to schizophrenia2

The microRNA miR-19 helps budding adult brain cells stay on track, new research indicates. The findings pave the way toward a better understanding of how the adult brain controls the growth of new neurons and how it can go wrong.

ACA's tobacco surcharges reduce smokers' insurance take-up, study finds2

A new study reveals an unexpected consequence of the Affordable Care Act's (ACA) tobacco surcharges: high surcharges resulted in lower rates of insurance enrollment among smokers in the first year of the ACA's implementation, without increasing smoking cessation. These effects are at odds with the ACA's mission of universal coverage.

Blood test to detect DNA fragments shed from colon cancers accurately predicts disease recurrence2

Scientists report they have used a genetic test that spots bits of cancer-related DNA circulating in the blood to accurately predict the likelihood of the disease's return in some -- but not all -- of a small group of patients with early-stage colon cancer.
