Pennsylvania became one of the first states in 2015 to implement a statewide standing order allowing pharmacists to dispense naloxone, an antidote for opioid overdoses, without a physician's prescription. This study looked at the availability (with or without a prescription) of naloxone nasal spray at 418 pharmacies in Philadelphia surveyed by telephone.
Examining to what extent firearm ownership and accessibility may be associated with suicide risk among US Army soldiers was the aim of this psychological autopsy study. The study included 135 soldiers who died by suicide on active duty between 2011-2013; firearms were the most common method with 61 of 111 soldiers who had a documented method of injury dying this way.
A new study finds that only one-third of pharmacies in Philadelphia carry naloxone nasal spray, a medication used to rapidly counter the effects of opioid overdose, and that many of the pharmacies that do carry the drug require patients to have a physician's prescription for it.
The faster fluid is removed using continuous dialysis from patients with failing kidneys, the higher the likelihood they will die in the next several months.

The rise of fake news in the American popular consciousness is one of the remarkable growth stories in recent years—a dizzying climb to make any Silicon Valley unicorn jealous. Just a few years ago, the phrase was meaningless. Today, according to a new Pew Research Center study , Americans rate it as a larger problem than racism, climate change, or terrorism. But remarkable though that may seem,
(Credit: Bumble Dee/Shutterstock) Since 2004, the rate of death by suicide has exceeded that of death by combat injury for American soldiers.

About 20% of breast cancers make abnormally high levels of a protein called human epidermal growth factor receptor 2 (HER2). When displayed on the surface of cancer cells, this signaling protein helps them proliferate uncontrollably and is linked with a poor prognosis. Now, researchers have developed a DNA nanorobot that recognizes HER2 on breast cancer cells, targeting them for destruction.
