Am I Safe Here?: How People With HIV/AIDS Perceive Hidden Prejudices in Their Communities

People in marginalized groups, such as the disabled or racial minorities, feel stigmatized—condemned, feared, or excluded—when other people stigmatize them. That’s obvious. But they can also feel stigma when nobody blatantly discriminates against them or says a negative word.

These folks aren’t paranoid, suggests a new study of HIV-positive people and their communities to be published in Psychological Science, a journal of the Association of Psychological Science. Rather, they’re picking up subtle clues from their communities. (more…)

U.S. Remains the Largest Cocaine Market in the World

Culture, General

The United States remains the world’s largest market for cocaine, with 4.8 million users, although its importance has been reduced in recent years, according to the INCB (International Board for Narcotics Control).

“In 2009, 4.8 million people consumed some form of cocaine in the U.S., compared with 5.3 million in 2008,” the INCB said in its report in 2010. With this number of consumers, the U.S. represents 41% of the international drug market, ahead of Europe, with 29%, according to the board, stating that “Although the market for cocaine has been reduced in North America, it continues to grow in Europe.” (more…)

Mating Mites Trapped in Amber Reveal Sex Role Reversal

Science

ANN ARBOR, Mich.— In the mating game, some female mites are mightier than their mates, new research at the University of Michigan and the Russian Academy of Sciences suggests. The evidence comes, in part, from 40 million-year-old mating mites preserved in Baltic amber.

In a paper published March 1 in the Biological Journal of the Linnean Society, researchers Pavel Klimov and Ekaterina Sidorchuk describe an extinct mite species in which the traditional sex roles were reversed. (more…)

Sleep More to Avoid Car Accidents and Bad Days at Work

Health

Less than seven hours of sleep each night is leading to a host of sleep-related problems including drowsy driving and difficulty concentrating at work, according to two new studies released on Thursday.

Roughly one-third of adults in 12 states reported getting less than seven hours of sleep each night with about the same number saying they’ve unintentionally dozed off during the day, according to one of the studies on sleep-related behavior from the Centers for Disease Control and Prevention.

JQI Physicists Demonstrate Coveted ‘Spin-Orbit Coupling’ in Atomic Gases

Science

Technique suggests an avenue for creating new kinds of superconductivity

COLLEGE PARK, Md. — Physicists at the Joint Quantum Institute (JQI), a collaboration of the University of Maryland and the National Institute of Standards and Technology (NIST), have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to quantum computing, next-generation “spintronics” devices and even “atomtronic” devices built from ultracold atoms.

Harmful Illusions Bedevil Ideas About Free Markets and Imprisonment, UChicago Professor Writes

Economy, Politics

The United States prizes freedom above most other civic values, yet Bernard Harcourt believes the notion is widely misunderstood and inconsistently applied.

Freedom from government interference is a key tenet of the free market system that the United States champions, but Harcourt notes that Americans expect vigorous government action in imprisoning criminals. The result is a deep inconsistency, he argues, for even as the United States preaches freedom in the marketplace, it maintains the world’s highest incarceration rate. (more…)

Spitzer Captures Infrared Rays From a Sunflower

Science

The various spiral arm segments of the Sunflower galaxy, also known as Messier 63, show up vividly in this image taken in infrared light by NASA’s Spitzer Space Telescope. Infrared light is sensitive to the dust lanes in spiral galaxies, which appear dark in visible-light images. Spitzer’s view reveals complex structures that trace the galaxy’s spiral arm pattern.

Messier 63 lies 37 million-light years away — not far from the well-known Whirlpool galaxy and the associated Messier 51 group of galaxies. (more…)

Just Like Me: Online Training Helpers More Effective When They Resemble Students

Education, Technology

Opposites don’t always attract. A study from North Carolina State University shows that participants are happier – and perform better – when the electronic helpers used in online training programs resemble the participants themselves.

“It is important that the people who design online training programs understand that one size does not fit all,” says Dr. Lori Foster Thompson, an associate professor of psychology at NC State and co-author of the study. “Efforts to program helper agents that may be tailored to individuals can yield very positive results for the people taking the training.” (more…)
