Marijuana for morning sickness? It’s not great for baby’s brain

With a growing number of states legalizing recreational or medical marijuana, more women are using the drug during pregnancy, in part due to its reported ability to relieve morning sickness. A new study, conducted in rats, sheds light on how cannabis exposure affects the brain of a develop | Read more...

‘Molecular surgery’ reshapes living tissue with electricity but no incisions

Traditional surgery to reshape a nose or ear entails cutting, sometimes followed by long recovery times and scars. Now, researchers have developed a 'molecular surgery' process using tiny needles, electric current and 3D molds to quickly reshape living tissue with no incisions, scarring or recovery time. It shows promise as a noninvasive alternative to laser ey | Read more...

How whales defy the cancer odds: Good genes

Scientists have studied potential cancer suppression mechanisms in cetaceans, the mammalian group that includes whales, dolphins and porpoises. Biologists picked apart the genome of the humpback whale, as well as the genomes of nine other cetaceans, in order to determine how their cancer defenses are so | Read more...

New treatment could become first targeted therapy designed for ‘untreatable’ childhood brain cancer

A new type of drug that targets a genetic weakness in an untreatable childhood brain cancer could become the first ever treatment designed to target the disease. The prototype treatment could also offer hope for patients with the rare and devastating 'stone man syndrome' -- in which muscles and ligaments tur | Read more...

Just 20 minutes of contact with nature will lower stress hormone levels, reveals new study

Taking at least 20 minutes out of your day to stroll or sit in a place that makes you feel in contact with nature will significantly lower your stress hormone levels. That's the finding of a study that has established for the first time the most effective dose of an urban nature experience. Healthcare practitioners can use this discovery to prescribe 'nature-pills' in the knowledge that they have a real measurab | Read more...
