Science and the sources of pain — Science News, October 26, 1974Chronic pain is no small problem for thousands of Americans. They take analgesics, sedatives or tranquilizers. They seek out chiropractors, acupuncturists or even miracle workers. Often they are not helped, at least over the long run…. The reason that so many people aren’t getting relief from pain is that clinicians still aren’t sure what pain is and how to treat it.

P.P.C. Graziadei and J.F. Metcalf of Florida State University have been producing … ever more detailed, evidence for olfactory nerve regeneration in mammals…. Might olfactory nerves be regenerated in people who have trouble smelling, thereby restoring or improving their sense of smell? “The phenomena of regeneration are applicable to all vertebrates and most likely to humans,” says Graziadei.

The time may be coming to wash our hands of plastic trash. Literally. About 60 percent of all plastic ever made ends up in landfills or littering the environment. Only about one-tenth of plastic waste is ever recycled, and much of that ends up being low-quality material reused in things like park benches (SN: 1/27/21). So chemists are searching for ways to “upcycle” plastic into more valuable raw materials. Now, there’s a way to turn old plastic into surfactants, researchers report in the Aug.

Fat incinerator. Metabolism booster. Thermo activator. Some over-the-counter sports supplements advertise ingredients with purported performance-enhancing properties, but it’s anyone’s guess what’s really in that pill or powder. Just 11 percent of nearly 60 tested dietary supplements actually contain an accurate amount of key ingredients listed on the label, scientists report July 17 in JAMA Network Open. Forty percent did not contain a detectable amount of the ingredients at all.

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — masses of cells created from stem cells that mimic some properties of certain stages of embryo development. The achievement gives researchers a chance to look at human development beyond the first week or so, when an embryo must implant in the uterus to develop further.

A mouse’s entire nervous system lights up in psychedelic hues. Clumps of immune cells attacking tumors give off a ghostly glow. The vessels that make up the body’s sewer system flare brightly. These and other images are shining a new light on the inner workings of mice, thanks to a new technique that makes whole body imaging cheaper and faster, researchers report July 10 in Nature Biotechnology. See-through mice are nothing new (SN: 8/14/14).

Giving birth to child who is unresponsive or struggling to breathe is a harrowing experience. The medical team must quickly cut the umbilical cord and then rush the baby to aid. But taking a few seconds to squeeze blood from the cord into an infant’s abdomen before cutting the cord could help with the infant’s recovery, two recent studies suggest. The practice, known as umbilical cord milking, is relatively unknown and not without some controversy.

Many female adolescents in the United States may not have enough iron in their bodies. But most may never know, partly due to a lack of routine screenings as well as disagreement over what constitutes too little iron, pediatric hematologist Angela Weyand argues. Iron deficiencies are most commonly diagnosed in toddlers, people who menstruate and pregnant people.
