Monkeys Pass on Brain Activity Patterns Linked to Anxiety

The Scientist Magazine

Patterns of brain activity associated with anxiety in monkeys are passed from parent to child, researchers report today (July 30) in the Journal of Neuroscience. The results could give clues to the heritability of severe anxiety in humans and how to treat it. In the study, Ned Kalin of the University of Wisconsin School of Medicine and Public Health and colleagues studied the stress response and cortisol levels of 378 young monkeys after an intruder entered the animal cage. The researchers also took scans of the monkeys’ brains while the animals were anesthetized and found that the monkeys with greater stress responses had differences in brain activity in the extended amygdala compared with those that were less stressed.

The weirdest things we learned this week: Curing syphilis with malaria, ejecting bears from planes, and discovering new beer yeasts

Popular Science

In 2009, a team of researchers at the University of Wisconsin-Madison, launched a five-continent search for the yeast mama. This portion of the genetics is what gives lager style beer its primary characteristic: the ability to ferment cold. The first hit came from Argentina, a 99.5 percent match from a growth on a beech tree. They named it Saccharomyces eubayanus.

Want To Connect With Your Audience? Use These 5 Tips To Stand Out

In 2016, researchers at the University of Wisconsin-Madison and Northwestern University found that curiosity could dramatically change people’s behavior for the better.  Among other things, they discovered that posting a trivia question next to an elevator and telling people the answer was in the stairwell could actually get more people to use the stairs!

Women’s reproductive history may predict Alzheimer’s risk

The Washington Post

Research at the conference also included updates to the associations between hormone therapy and Alzheimer’s risk. Previous studies had suggested that women who start taking hormones in their late 60s and 70s have a higher rate of cognitive decline, a paper out of the University of Wisconsin school of medicine and public health found that risk to be elevated specifically for women with diabetes.

Wisconsin researchers study genetic screening for Amish

“We want to be able to offer very rapid, low-cost confirmatory testing of genetic disorders,” said Dr. Christine Seroogy, a pediatric immunologist and associate professor at the UW School of Medicine and Public Health. “Additionally, it could be cost-saving, in that we are diagnosing the disorders early, which saves the families lots of diagnostic testing.”

Climate Change Could Affect The Internet Thanks To Rising Sea Levels, A New Study Suggests

Bustle

It’s a hallmark of modern apocalypse movies: Someone tries their cellphone, and when they (gasp!) have no reception, they try the internet. That’s when the real horror hits, because the internet isn’t working, and not even memes can save them now. All joking aside, though, climate change does pose a real threat to the internet, according to a new study. The report suggests that underground fiber optic cables that provide internet to heavily populated areas along the West and East Coasts of the U.S. may be underwater within the next 15 years.

The Internet is Drowning

When the Internet goes down, life as the modern American knows it grinds to a halt. Gone are the cute kitten photos and the Facebook status updates—but also gone are the signals telling stoplights to change from green to red, and doctors’ access to online patient records.

How rising seas could cause your next internet outage

You probably didn’t give much thought to how exactly you loaded this webpage. Maybe you clicked a link from Twitter or Facebook and presto, this article popped up on your screen. The internet seems magical and intangible sometimes. But the reality is, you rely on physical, concrete objects — like giant data centers and miles of underground cables — to stay connected.

UW professor’s dream leads to breakthrough in identifying origin of cosmic rays

Milwaukee Journal Sentinel

For more than a century, the origin of cosmic rays — fragments of atoms that rain down on the Earth at close to the speed of light — had been one of the great mysteries in science, thwarting the best minds in physics.An international team of scientists (including at UW–Madison) reported Thursday that the likely solution arrived at just after 3:54 p.m. Central Time on Sept. 22, in a scene beyond anything special effects wizards in Hollywood could have imagined.

Astronomers trace cosmic ray neutrino back to remote blazar

Astronomy Now

The initial detection by the IceCube Neutrino Observatory in Antarctica, and subsequent observations of high energy radiation from the same source by space telescopes and ground-based observatories, indicate such black holes act as the particle accelerators responsible for at least some of those cosmic rays.“The evidence for the observation of the first known source of high-energy neutrinos and cosmic rays is compelling,” said Francis Halzen, a University of Wisconsin–Madison professor of physics and the lead scientist for the IceCube Neutrino Observatory.

What’s a Blazar? A Galactic Bakery for Cosmic Rays

Wired

Scientists have finally located a source of the most energetic rays. Starting with a single signal—a flash of light in a detector at the South Pole—and combining it with telescope data from a collaboration of over a thousand people, astrophysicists have traced the origin of some of Earth’s cosmic rays to a blazar, a type of galaxy, 4 billion light years away. “We’ve learned that these active galaxies are responsible for accelerating particles and cosmic rays,” says physicist Francis Halzen of the University of Wisconsin-Madison.

Is ‘Doing Time’ Money for Private Prisons?

Correctional News

Noted: Inmates in private prisons appear to serve 4 to 7 percent additional fractions of their sentences, which amounts to 60 to 90 days for the average inmate, according to a paper released by Anita Mukherjee, Ph.D., an assistant professor of actuarial science, risk management and insurance at the University of Wisconsin-Madison’s Wisconsin School of Business.

An Astrophysics ‘Breakthrough’ Will Be Unveiled Thursday. Here’s How to Watch.

An international team of astrophysicists will reveal a “breakthrough” discovery Thursday (July 12), and you can watch the announcement live.The U.S. National Science Foundation (NSF) announced in a statement that it will host a news conference Thursday at 11 a.m. EDT (1500 GMT) to unveil new “multimessenger astrophysics findings” led by the IceCube Neutrino Observatory, an NSF-managed facility at the South Pole.

Many Creative Geniuses May Have Procrastinated—but That Doesn’t Mean You Should

Noted: The intersection of creativity and procrastination gathered mainstream buzz in 2016, when the New York Times published an op-ed by Adam Grant, an organizational psychologist, author, and Wharton School of Business professor. In the piece “Why I Taught Myself to Procrastinate,” Grant posits procrastination as a “virtue for creativity” and shares the research of one of his students, Jihae Shin, now a professor at the Wisconsin School of Business.

New app sets out to learn what makes ticks ‘tick’

The Country Today

Researchers at UW-Madison have developed a new smartphone app to help them understand where ticks are active and how people expose themselves to ticks. The app is being released as Wisconsin faces an ever-increasing number of Lyme disease cases, sparking heightened concern about tick-transmitted diseases.
