Social media study guides risk-reduction videogame for Black teen girls

To support the development of a multiplayer risk-reduction videogame for Black teen girls, researchers at Yale conducted a study that sheds light on the social media habits of these teens in evaluating and choosing potential romantic partners. The results were published in the July 24 issue of Social Media & Society.

Developing probiotic beverages without animal protein

Most products enriched with probiotics and protein are made with dairy products. However, consumer demand for plant protein is growing. The nutritional value of these proteins must therefore be improved to be comparable to that of animal proteins.

A reversible male contraceptive, targeted to the testes with magnets

Women have several choices for long-lasting, reversible contraceptives, but most options for men are either single-use, such as condoms, or difficult to reverse, like vasectomies. Now, in a step toward a safe, long-lasting and reversible male contraceptive, researchers reporting in ACS' Nano Letters have developed magnetic, biodegradable nanomaterials that reduced the likelihood of mice fathering...

A caffeine buzz helps bees learn to find specific flowers

Researchers have shown that feeding bumble bees caffeine helps them better remember the smell of a specific flower with nectar inside. While previous studies have shown that bees like caffeine and will more frequently visit caffeinated flowers to get it, this study shows that consuming caffeine in their nest actually helps bees find certain flowers outside of the nest.

Researchers develop 'dimmer switch' to help control gene therapy

In a major advancement in the field of gene therapy for rare and devastating diseases, researchers have developed a "dimmer switch" system that can control levels of proteins expressed from gene therapy vectors. The system is based on alternative RNA splicing using an orally available small molecule and works effectively in tissues throughout the body, including the brain.

Nearly half of surveyed female surgeons experienced major pregnancy complications

Researchers surveyed 1,175 surgeons and surgical trainees from across the U.S. to study their or their partner's pregnancy experiences. They found that 48 percent of surveyed female surgeons experienced major pregnancy complications, with those who operated 12-or-more hours per week during the last trimester of pregnancy at a higher risk compared to those who did not.

Chaotic electrons heed 'limit' in strange metals

Electrons in metals try to behave like obedient motorists, but they end up more like bumper cars. They may be reckless drivers, but a new Cornell-led study confirms this chaos has a limit established by the laws of quantum mechanics.

‘Wiggly’ fossils found in Canada may be earliest known animal

Scientists believe the unusual tubular structures may be the remnants of prehistoric spongesIntricate patterns of tubular structures discovered in giant ancient reefs may be the remnants of prehistoric horny sponges and the oldest known fossils of animal life on Earth.Researchers found the unusual features in vast reefs that were built by bacteria 890m years ago and then pushed up by geological...

Man's new best friend: What cats can teach us about human genetics and precision medicine

Although cats have lived alongside humans for millennia, it remains a dogs' world. This bias has historically bled into science as well. It's time for cats to get their day, argues veterinary medicine expert Leslie Lyons in a Forum published July 28 in the journal Trends in Genetics. Cats, she says, have the potential to be a valuable model organism for geneticists, as the feline genome is ordered...
