The Centers for Disease Control recently released survey results from kids showing that many of them had seen some form of advertisement for e-cigarettes. Then they matched them to the uptick in e-cigarette use among young people and implied causation.

There is good news in the annual data report from the United States Renal Data System, coordinating center based at the University of Michigan Kidney Epidemiology and Cost Center, in partnership with Arbor Research Collaborative for Health. 

PROVIDENCE, R.I. [Brown University] -- Combining the drug topiramate with psychological counseling curbed marijuana use among young smokers significantly more than did counseling alone, according to newly published results of a small randomized, controlled trial at Brown University. The results come with a caveat, however: many study volunteers couldn't tolerate the medicine's side effects.

There is no FDA-approved medication for treating cannabis dependence and misuse. Meanwhile, the benefits of counseling treatment, such as motivational enhancement therapy (MET), aren't enough to help many patients, said Robert Miranda Jr., associate professor (research) of psychiatry and human behavior in the Alpert Medical School.

A team of authors from MIPT, Kansas State University, and the U.S. Naval Research Laboratory have demonstrated that it is possible to fully absorb electromagnetic radiation using an anisotropic crystal. The observations are of fundamental importance for electrodynamics and will provide researchers with an entirely new method of absorbing the energy of electromagnetic waves. The paper has been published in Physical Review B.

For as much time as Americans spend saying it is the greatest country on Earth, a whole lot of people worry about creating safe spaces where free expression is not allowed, or protesting the behavior of people they don't like.

When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theoretical physicists, who have increasingly migrated toward making up stuff using math, now claim using such numbers that quantum theories of gravity must also have a 'rainbow' of sorts, composed of different versions of spacetime. They further predict that instead of a single, common spacetime, particles of different energies essentially sense slightly modified versions.
