'White graphene' halts rust in high temps

Researchers have discovered that sheets of hexagonal boron nitride can protect metals from oxidizing even at very high temperatures, such as 1,100 degrees Celsius. The ultrathin films are made of just a few atoms thick and have potential applications in industries like turbines, jet engines, and oil exploration.

Study explains why diabetic retinopathy is difficult to treat

Researchers investigated how drug treatment affects signal carriers in diabetic retinas, finding half of proteins normalized by metformin treatment. However, other essential proteins remained unchanged despite improved blood glucose levels, suggesting a need for further combination therapies to effectively treat diabetic retinopathy.

Overhauling confusing prescription medicine labels

A new study is testing a standardized labeling system that prescribes medications at four specific times of the day (morning, noon, evening, and bedtime), with the goal of improving patients' understanding and proper use of their medications. The study aims to reduce confusion and neglect among patients taking multiple medications.

Meals for more seniors could save some states money

A new study by Brown University researchers projects that expanding home-delivered meal programs to 1% more seniors would save most states money, with Pennsylvania seeing the greatest net savings of $5.7 million annually. This expansion would enable 1,722 more Medicaid recipients to avoid nursing homes and improve their quality of life.

Infanticide linked to wet-nursing in meerkats

Researchers found that subordinate female meerkats who have recently lost litters or been evicted are more likely to wet-nurse the dominant female's pups. This behavior may provide a survival benefit for the nursed offspring and the mother of the pups, allowing the subordinate female to remain in the group.

Targeting canine bloat, a major killer of dogs

Canine bloat is a leading cause of death in dogs, with Great Danes being the most prone. Researchers are investigating the relationship between motility and bloat risk, as well as genetic factors, to develop diagnostic tools and potentially prevent the disease. SmartPill, a non-invasive diagnostic tool, will be used to measure acidity ...

Poor nutritional status before bladder operation causes higher risk of complications

A new study by the University of North Carolina School of Medicine has identified low preoperative albumin levels as an independent risk factor for surgical-related health problems after radical cystectomy. Patients with a low albumin level before surgery are 2.1 times more likely to experience complications within 30 days.
