Study links fox domestication to gene activity in the pituitary gland

A study of foxes offers new insights into the brain changes that occur in wild canids as they become more tame, researchers report. The study links fox domestication to changes in gene activity in the pituitary gland, a brain center that kicks out hormones to regulate various bodily functions, including the stress response.

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.

How do sexual assault survivors fare?

Whether or not survivors share their stories publicly, they often carry lifelong scars associated with being sexually traumatized

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.

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.
