The Placebo Effect Goes Beyond Humans, UF Researchers Find

GAINESVILLE, Fla. — Rats and humans have at least one thing in common: They both react the same way to a placebo, according to a new University of Florida study.

“That was the big finding — that the animals that expected pain relief actually got pain relief when you gave them an inert substance,” said co-author John Neubert, a pain specialist and an associate professor with the UF College of Dentistry department of orthodontics. “It helps validate our model that what we do in the rats, we believe, is a good representation of what’s being seen in humans.”

The investigation of placebo effects might lead to the identification of new therapeutic targets in the brain and of novel treatment strategies for a variety of health conditions. (more…)

Modeling the Breaking Points of Metallic Glasses

Mathematical methods developed by a Berkeley Lab researcher help explain why liquid metals have wildly different breaking points, depending on how they are made

Metallic glass alloys (or liquid metals) are three times stronger than the best industrial steel, but can be molded into complex shapes with the same ease as plastic. These materials are highly resistant to scratching, denting, shattering and corrosion. So far, they have been used in a variety of products from golf clubs to aircraft components. And, some smartphone manufacturers are even looking to cast their next-generation phone cases out of it. (more…)

Advocate for Women in STEM Disciplines Speaks on Today’s Barriers to ‘Breaking into The Lab’

For Sue Rosser, the obstacles women in the STEM disciplines face today may be less obvious than they were 40 years ago, but they’re as real as ever.

“Today, barriers and discrimination are more subtle and there’s a different language, but it’s still going on,” Rosser said. “It’s old wine in new bottles.”

Rosser, the first woman to serve as provost and vice president for academic affairs at San Francisco State University, presented “Breaking into the Lab: Engineering Progress for Women in Science,” on Nov. 12, at the Knapp Center for Biomedical Discovery. Her talk outlined barriers to women’s advancement in scientific fields, and offered advice for women and academic mentors to avoid discrimination. The event, which is part of the annual lecture series, “How to Advance Women in Science and Engineering,” is a collaboration between the Center for the Study of Gender and Sexuality and the Office of the Provost at the University of Chicago. Rosser’s talk is the second annual colloquium on how to support and advance women in the STEM fields. (more…)

International Study Provides More Solid Measure of Shrinking in Polar Ice Sheets

The planet’s two largest ice sheets have been losing ice faster during the past decade, causing widespread confusion and concern. A new international study provides a firmer read on the state of continental ice sheets and how much they are contributing to sea-level rise. (more…)

Texas Astronomers Measure Most Massive, Most Unusual Black Hole Using Hobby-Eberly Telescope

FORT DAVIS, Texas — Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin’s McDonald Observatory to measure the mass of what may be the most massive black hole yet — 17 billion times our sun’s mass — in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy’s mass, rather than the usual 0.1 percent. This galaxy and several more in the same study could change theories about how black holes and galaxies form and evolve. The work will appear in the journal Nature on Nov. 29.

NGC 1277 lies 220 million light-years away in the constellation Perseus. The galaxy is only 10 percent the size and mass of our Milky Way. Despite NGC 1277’s diminutive size, the black hole at its heart is more than 11 times as wide as Neptune’s orbit around the sun. (more…)

Attitudes Towards Security Threats Uncovered

New research has revealed a significant gap between what the government claims are the biggest security threats facing the UK and the fears of the population.

Terrorism is not perceived as the most important threat to everyday life despite claims by policy makers.

Politics researchers at the Universities of Exeter and Warwick led detailed focus groups across the UK and conducted a nationwide survey as part of an Economic and Social Research Council (ESRC) funded project which looked at public attitudes towards security threats. (more…)
