A new study calculates a formula — 30 minutes of exercise for every 4 hours of inactivity — that can lower the risk of an early death from a sedentary lifestyle. In other public health news, the 'Ice Bucket Challenge' actually helped those with ALS, doctors tackle the question of what happens to the brain while a patient is under hypnosis and more stories.

A New Formula For Exercise? Study Suggests 1 Hour Of Activity Per 8 Hours Of Sitting
If you fear you're doing irreparable damage to your body because your white-collar job keeps you sitting at your desk from 9 to 5, or you regularly spend entire weekends sprawled out on your couch binge-watching Netflix, there's some good news just out from sports medicine researchers. According to a study published in The Lancet, all is not lost. You may be able to "make up" for your increased risk of death due to a sedentary lifestyle by engaging in enough physical activity. So just how much is enough? (Cha, 7/28)

Attention Desk Jockeys: Those Who Sit At Work Need An Hour Of Exercise A Day
If you want to offset the health hazards of sitting at your desk all day, you’ll need to dedicate yourself to an hour of moderate exercise a day, according to a new analysis. Previous studies had already shown that lack of physical activity, and spending lots of time sitting, both have negative health effects — including cardiovascular disease, diabetes, cancer, and early death. But nobody had done a systematic review looking at the two combined. (Swetlitz, 7/27)

The ‘Ice Bucket Challenge’ Helped Scientists Discover A New Gene Tied To A.L.S.
It turns out those much-mocked Ice Bucket Challenge videos helped do a lot of good. Two summers ago, the challenge, designed to raise money for research into amyotrophic lateral sclerosis, also known as Lou Gehrig’s disease, took the internet by storm. Supporters ended up raising over $115 million for the A.L.S. Association. Over two years, money from the challenge has helped fund the research and development of treatment drugs and has been used as prize money to entice people to design technology for people living with the disease, which causes a rapid breakdown in a person’s ability to control muscle movement.

In Patients Under Hypnosis, Scientists Find Distinctive Patterns In The Brain
Psychiatrists have been using hypnosis on patients for decades — to help them reduce their pain or kick a smoking habit, among other reasons. But what, exactly, is happening to the patients’ brains when they are in a hypnotic state? To tackle that question, David Spiegel, a psychiatrist at Stanford University School of Medicine, and his colleagues recently decided to scan patients’ brains and see if hypnosis left a mark. It did.

E-Cig Vapor Releases Two Cancerous Chemicals, New Study Says
Vapor from electronic cigarettes contains two previously undiscovered cancer-causing chemicals, according to a new study. Researchers at the Lawrence Berkeley National Laboratory found propylene glycol, an eye and respiratory irritant, and glycerin, a skin, eye and respiratory irritant, among 29 other chemicals released in e-cigarette vapor. Both are considered “probable carcinogens” by federal health officials. They’re used in e-cigarettes to create artificial smoke. (Bogage, 7/28)

Could ‘Brain Training’ Games Actually Work? New Study Surprises Scientists
We’ve seen — and done — some negative coverage of the so-called brain training industry, in which companies provide computerized games that ostensibly improve memory, attention, and other mental capabilities while — so some of the ads suggested — warding off cognitive decline. In January, one of the leading brands in this space, Lumosity made a deal with the Federal Trade Commission to cough up $2 million for partial refunds as compensation for deceptive advertising.
