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.

Agricultural fungicide attracts honey bees, study finds

When given the choice, honey bee foragers prefer to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone, researchers report in the journal Scientific Reports.

Many Midwestern retailers sell mislabeled invasive vines

Gardeners hoping to celebrate the beauty of American bittersweet – a native vine that produces orange berries in the fall and is used for wreaths – may be unwittingly buying an invasive bittersweet instead. That’s because many Midwestern retailers are selling oriental bittersweet with labels misidentifying it as the native plant, researchers report. These sales are occurring in stores and online.

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.

Study: Viruses share genes with organisms across the tree of life

A new study finds that viruses share some genes exclusively with organisms that are not their hosts. The study, reported in the journal Frontiers in Microbiology, adds to the evidence that viruses are agents of diversity, researchers say.

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.
