Sleep problems in menopause linked to hot flashes, depression - and may not last

A new study of middle-aged women found that sleep problems vary across the stages of menopause, yet are consistently correlated with hot flashes and depression.

Tiny drug-delivering capsules could sustain transplanted insulin-producing cells for diabetics

A drug-carrying microsphere within a cell-bearing microcapsule could be the key to transplanting insulin-secreting pig pancreas cells into human patients whose own cells have been destroyed by type I diabetes.

Lessons in nature boost classroom engagement afterward, researchers report

Third-graders who spend a class session in a natural outdoor setting are more engaged and less distracted in their regular classroom afterward than when they remain indoors, scientists found in a new study.

Preterm babies may suffer setbacks in auditory brain development, speech

Preterm babies born early in the third trimester of pregnancy are likely to experience delays in the development of the auditory cortex, a brain region essential to hearing and understanding sound, a new study reveals. Such delays are associated with speech and language impairments at age 2, the researchers found.

Hormone therapy combination may benefit health without increasing cancer risk

Treating ovariectomized mice with a combination of conjugated estrogens and the drug bazedoxifene triggers the expression of genes that improve metabolism and prevent weight gain – without stimulating the uterus and increasing risks of reproductive cancer, a new study at the University of Illinois suggests.

Whole eggs better for muscle building and repair than egg whites, researchers find

People who consume 18 grams of protein from whole eggs or from egg whites after engaging in resistance exercise differ dramatically in how their muscles build protein, a process called protein synthesis, during the post-workout period, researchers report in a new study. Specifically, the post-workout muscle-building response in those eating whole eggs is 40 percent greater than in those consuming an equivalent amount of protein from egg whites, the team found.

Molecular beacon signals low oxygen with ultrasound

Researchers have developed a way to find hypoxia, or low oxygen in tissue, noninvasively in real time with light and ultrasound.

Exercise changes gut microbial composition independent of diet, team reports

Two studies – one in mice and the other in human subjects – offer the first definitive evidence that exercise alone can change the composition of microbes in the gut. The studies were designed to isolate exercise-induced changes from other factors – such as diet or antibiotic use – that might alter the intestinal microbiota.

Drug-delivering nanoparticles seek and destroy elusive cancer stem cells

Researchers are sending tiny drug-laden nanoparticles on a mission to seek and destroy cancer stem cells.
