Placenta wrap hastens erection recovery after prostate surgery | New Scientist (opens the original)
Read excerpt
Erectile dysfunction is common after prostate cancer surgery, but wrapping thin sheets of dried placenta around exposed nerves during the procedure may allow faster recovery. A review of thousands of surgeries suggests that this approach enables an erection within one week of surgery, compared with two weeks without the intervention. “To help men get better erections, we’re using donations [of placentas] from women,” says Shirin Razdan at HCA Florida Kendall Hospital in Miami. We are finally imp
Should we use GLP-1 drugs to treat obesity in children? | New Scientist (opens the original)
Read excerpt
A small but growing proportion of children under the age of 12 with obesity are being prescribed GLP-1 drugs to help them lose weight. There are signs that this successfully treats obesity, but there are also concerns about the drugs’ long-term effects. So, is this trend likely to continue, and should it? Earlier this month, a study led by Babak Orandi at New York University found that 9.3 per cent of children in the US aged 8 to 11 with obesity but without diabetes are being prescribed GLP-1 me
Our brain evolved from two primitive nervous systems that merged | New Scientist (opens the original)
Read excerpt
Our brain may be a hybrid of two ancient nervous systems that were packaged together hundreds of millions of years ago. This is based on the finding that the front and back brain regions in people and several other species develop from two distinct cell types in embryos, instead of sharing the same developmental origin, as previously thought. “Our research suggests that evolution took two existing neural systems and pushed them together spatially,” says Kyle Loh at Stanford University. “Having t
We may finally know what kick-starts muscle contractions in childbirth | New Scientist (opens the original)
Read excerpt
What sets off labour when a baby is ready to be delivered has long been a mystery, but now it seems that the immune system pulls the trigger. The uterus appears to start contracting after immune cells transfer energy to its muscle cells via tiny tubes. “By understanding all the steps along the road, we’re getting closer to identifying therapeutics for preventing preterm birth,” says Stephen Lye at Mount Sinai Hospital in Toronto, Canada. Childbirth for many primate species is even harder than fo
Earliest evidence of habitual drug use found in teeth in Indonesia | New Scientist (opens the original)
Read excerpt
Teeth uncovered in Indonesia that are up to 25,000 years old show signs of the person having sucked on whole betel nuts, probably to release pain-relieving compounds. The finding represents the oldest archaeological evidence of habitual drug use in humans, dating back even further than the earliest-known beer-brewing. “We really don’t know much about the origins of our most widely used psychoactive substances, so to find that, up to 25,000 years ago, hunter-gatherers were already addicted to pla
