For anxious spouses, a baby may be a rival

A new child can spark feelings of jealousy in a person who already fears being abandoned by his or her partner, research suggests. A new study found that partners who showed signs of relationship anxiety before the birth of their first child were more likely to be jealous of the child after it was born.

Magnetic whirls in future data storage devices

Magnetic (anti)skyrmions are microscopically small whirls that are found in special classes of magnetic materials. They could be used to host digital data. A team of scientists has now made the observation that skyrmions and antiskyrmions can coexist bringing about the possibility to expand their capabilities in storage devices.

Study explores sexual harassment at AADR conferences

The American Association for Dental Research (AADR) released findings of a new research study, "Survey of Dental Researchers' Perceptions of Sexual Harassment at AADR Conferences: 2015-2018" in the Journal of Dental Research (JDR).

Researchers develop new explanation for destructive earthquake vibrations

Earthquakes produce seismic waves with a range of frequencies, from the long, rolling motions that make skyscrapers sway, to the jerky, high-frequency vibrations that cause tremendous damage to houses and other smaller structures. A pair of Brown University geophysicists has a new explanation for how those high-frequency vibrations may be produced.

Manipulating atoms to make better superconductors

Scientists have been interested in superconductors—materials that transmit electricity without losing energy—for a long time because of their potential for advancing sustainable energy production. However, major advances have been limited because most materials that conduct electricity have to be very cold, anywhere from -425 to -171 degrees Fahrenheit, before they become superconductors.

Does your cat have degenerative joint disease?

With an estimated 10-15% of adults over the age of 60 having some degree of osteoarthritis, otherwise known as degenerative joint disease (DJD), many people will be familiar with, or will know someone who suffers from, this painful and debilitating condition. What is not well recognised is that DJD, where the protective cartilage that cushions the end of the bones wears down over time, affects a...

With 30,000 surveys, researchers build the go-to dataset for smallholder farms

Top-down projects for improving the lives of poor farmers were often unsuccessful because they didn't systematically consider the diverse rural households survive and thrive. To tap this local knowledge, scientists and development agencies began surveying households to assure that research and development schemes were on target. But the surveys were not designed to be compared with one another,...

Chemists inhibit a critical gear of cell immortality

One of the hallmarks of cancer is cell immortality. A Northwestern University organic chemist and his team now have developed a promising molecular tool that targets and inhibits one of cell immortality's underlying gears: the enzyme telomerase.

New DNA origami motor breaks speed record for nano machines

Through a technique known as DNA origami, scientists have created the fastest, most persistent DNA nano motor yet. Angewandte Chemie published the findings, which provide a blueprint for how to optimize the design of motors at the nanoscale—hundreds of times smaller than the typical human cell.

The catch to putting warning labels on fake news

After the 2016 U.S. presidential election, Facebook began putting warning tags on news stories fact-checkers judged to be false. But there's a catch: Tagging some stories as false makes readers more willing to believe other stories and share them with friends, even if those additional, untagged stories also turn out to be false.
