With just over two months before the 2020 election, three professors at the Indiana University Kelley School of Business offer a comprehensive review of how other nations are seeking to protect their democratic institutions and presents how a multifaceted, targeted approach is needed to achieve that goal in the U.S., where intelligence officials have warned that Russia […]
Beavers appear to help the growth of brown trout in South America, study finds

Posted: 02 Sep 2020 08:11 AM PDT

In the early 1900s, brown trout and rainbow trout were introduced to southern South America for recreational fishing and early aquaculture initiatives. About 40 years later, American beaver were introduced in the same region to develop a felt industry. That history intrigued Ivan Arismendi, an aquatic ecologist at Oregon State University. He is originally from […]
Scent-Sensing Cells Have a Better Way to Fight Flu

Posted: 02 Sep 2020 08:09 AM PDT

Influenza researchers have long focused most of their efforts on the epithelial cells lining the lungs because these are the cells that become infected and killed while producing new copies of the virus. But other cells lining the upper airways are exposed to viruses in the same amounts and somehow aren’t as likely to be […]

According to survey results from an […]
Your paper notebook could become your next tablet

Posted: 02 Sep 2020 08:07 AM PDT

Innovators from Purdue University hope their new technology can help transform paper sheets from a notebook into a music player interface and make food packaging interactive. Purdue engineers developed a simple printing process that renders any paper or cardboard packaging into a keyboard, keypad or other easy-to-use human-machine interfaces. This technology is published in the Aug. 23 […]
An unexpected origin story for a lopsided black hole merger

Posted: 02 Sep 2020 08:04 AM PDT

A lopsided merger of two black holes may have an oddball origin story, according to a new study by researchers at MIT and elsewhere. The merger was first detected on April 12, 2019 as a gravitational wave that arrived at the detectors of both LIGO (the Laser Interferometer Gravitational-wave Observatory), and its Italian counterpart, Virgo. […]
A “Bang” in LIGO–Virgo Detectors Signals Most Massive Gravitational-Wave Source Yet

Posted: 02 Sep 2020 08:03 AM PDT

For all its vast emptiness, the universe hums with activity in the form of gravitational waves. Produced by extreme astrophysical phenomena, these reverberations ripple forth and shake the fabric of space-time, like the clang of a cosmic bell. Now researchers have detected a signal from what may be the most massive black hole merger yet […]
What’s different about recent athlete protests?

Posted: 02 Sep 2020 07:59 AM PDT

How do people coordinate their actions with the sounds they hear? This basic ability, which allows people to cross the street safely while hearing oncoming traffic, dance to new music or perform team events such as rowing, has puzzled cognitive neuroscientists for years. A new study led by researchers at McGill University is shining a […]
Female Chromosomes Offer Resilience to Alzheimer’s

Posted: 02 Sep 2020 07:55 AM PDT

Women with Alzheimer’s live longer than men with the disease, and scientists at UC San Francisco now have evidence from research in both humans and mice that this is because they have genetic protection from the ravages of the disease. By virtue of having a second X chromosome, women get two “doses” of a protective […]
