In its first clinical trial, an antibody therapy produced at least partial remissions in a third of patients with multiple myeloma who had exhausted multiple prior treatments, investigators at Dana-Farber Cancer Institute and other organizations have reported.

The drug, daratumumab, proved generally safe in patients, even at the highest doses tested in the study. The results of the trial - a combined phase 1 and 2 study - strongly support testing of the drug in a larger group of patients in both phase 2 and 3 trials, the authors say.

Male teens who experiment with cannabis before age 16, and have a high genetic risk for schizophrenia, show a different brain development trajectory than low risk peers who use cannabis.

The discovery, made from a combined analysis of over 1,500 youth, contributes to a growing body of evidence implicating cannabis use in adolescence and schizophrenia later in life. 

This is just for fun. At first sight this seems impossible - the smallest stars are heavier than the heaviest planets, and how can something heavier orbit something that is lighter? But what if you have a very dense star and very large very low density planet? And if you interpret "orbiting it" as "having barycenter (the "center of mass of the system") within the planet"?

Also, could a star sometimes be lighter than a planet, is that possible at all? I'll also describe a way that a heavier object can, in a way, "orbit" a lighter one - a way to get a heavier star move in such a way that the barycenter of the system lies within a large low density planet - can you figure out how, before I get to it?

A new study clearly establishes a partial genetic basis underlying racial differences in slow-wave sleep, suggesting that it may be possible to develop sleep-related therapies that target specific genetic variants.

Using a panel of 1,698 ancestry informative genetic markers, the study found that greater African genetic ancestry was associated with lower amounts of slow-wave sleep in African-American adults. African ancestry explained 11 percent of the variation in slow-wave sleep after adjustment for potential confounders. Although a similar association was observed for delta power, no association with African ancestry was observed for sleep duration and efficiency.

A scientist named Kevin Folta at the University of Florida has been one of a broader group of public researchers who have come under hostile, Freedom Of Information Act scrutiny with the goal of demonstrating “ties to industry.” 

More than a quarter of a million people die each year that are linked to using smokeless tobacco, say scholars who believe that governments need to consider incorporating the regulation of smokeless tobacco into policy frameworks.

A paper funded by Leeds City Council and the Medical Research Council links smokeless tobacco to more than 62,000 deaths due to cancers of the mouth, pharynx and oesophagus and accounted for more than 200,00 deaths from heart disease in 2010.

Licensed tobacco retailers throughout New York City are selling a substantial number of cigarette packs carrying either counterfeit or out-of-state tax stamps, finds an investigation by NYU public health researchers.

These illegal cigarette sales are more pervasive in independent stores, as opposed to chain stores.
