The Trump administration has issued a notice of proposed rulemaking (NPRM) that would allow for the importation of certain prescription drugs from Canada. In addition, the Administration is announcing the availability of a new draft guidance for industry that describes procedures drug manufacturers can follow to facilitate importation of prescription drugs, including biological products, that are FDA-approved, manufactured abroad, authorized for sale in any foreign country, and originally intended for sale in that foreign country.

Mitochondria, the energy factories in most of our cells that convert the fat, carbohydrates, and protein we eat into a common energy currency used by our bodies, also set off molecular alarms when cells are exposed to stress or chemicals that can damage DNA, such as chemotherapy, according to a new study in Nature Metabolism.

This basic research could one day lead to applied science, like cancer treatments that prevent tumors from becoming resistant to chemotherapy.

In March of 1869,  the chemist Dmitri Ivanovich Mendeleev made a presentation to the Russian Chemical Society and outlined patterns in elements that led him to postulate his periodic table of the existing 63 elements. Since a new one was being discovered about once per year, he also made sure to leave room for additions and even hypothesized a few more.

Chemistry was the future, understanding elements was key, he and others believed, and they turned out to be right. If you are reading this article on a cell phone, notes New York University, you're holding at least 30 different naturally-occurring elements, including lithium. 

Blocking a key regulator of the immune system helps unleash the body's natural defenses against several forms of cancer, a discovery which opened up a new era of cancer immunotherapy. 

Now researchers have flipped this script and found that, when impaired, a molecularly similar regulator can cause the damaging immune system attacks on skin and organs that are the hallmark of the autoimmune disease lupus. Though still just in the exploratory stage, mice are not little people so this does not translate to humans, the work suggests a way to restore function of this inhibitor which could one day provide new therapy to treat the disease.

Since 2007, claim lines with diagnoses of Lyme disease increased nationally 117 percent, according to a new white paper.

A new study found that people given accurate statistics on a controversial issue misremembered those numbers to fit commonly held beliefs.

That means the source of fake news is often not malevolent organizations manipulating social media, it is people convinced they are correct.
