Are test tube burgers coming to a grocery store near you? Sounds like science fiction, and until recently, it actually was.
Now, the prospect of lab-grown meat appearing on our supermarket shelves is closer than ever. We aren’t talking about the whole cow, however. That would be an “udderly” different story.
Synthetic or test-tube meat involves taking a small amount of cells from a living animal and growing it into lumps of muscle tissue in the lab. In theory, this can then be turned into meat for human consumption.
Scientists believe lab-grown meat …
Many experts believe that pupil dilation can reveal sexual orientation when a person looks at attractive people, yet until now, there was no research supporting that theory. A new study by researchers at Cornell University, published in the journal PLoS ONE, measured pupillary changes of participants watching erotic videos by using a specialized infrared lens. Pupils widened most when a person was watching a video with people they found attractive, which then revealed where the volunteers fell on the sexual spectrum from heterosexual to homosexual.
Researchers in the past have explored …
The spray was tested on 228 people with leg ulcers, which are painful open wounds that can last for months.
The findings, published in the Lancet, showed that ulcers treated with the spray were more likely to heal and did so more quickly.
Experts said faster healing could save money despite the cost of the spray.
Leg ulcers are hard to treat. The best treatment, compression bandages, will heal only about 70% of ulcers after six months. Other options include taking skin from somewhere else on the body and grafting it over the …
Three new studies of cancer in the brain, skin and gut, appear to support the controversial idea that cancer may have its own stem cells that drive the regrowth of tumors. If confirmed with more evidence, the idea may transform our understanding of cancer and how it should be treated.
Papers on all three studies appeared online on Wednesday, two in Nature and one in Science.
In all three studies, the teams used genetic cell-marking techniques to track cell lineage and show that a restricted cell population appears to be the source …
A new study from the American Academy of Pediatrics challenges the age-old schoolyard taunt, suggesting that words can, in fact, hurt children. Though they may not realize it, parents who bully or demean their children could cause long-lasting harm. As their life progresses, these children might not seek the help they need to recover from these damages.
“Psychological maltreatment is just as harmful as other types of maltreatment,” says the report in an upcoming Pediatrics journal. The new study points out that while it’s difficult to know exactly when a child …
