In these modern times, people can have jobs that weren't traditionally associated with their genders. Men are nurses; women are CEOs. A new study examines perceptions of people in high-powered jobs and finds that they're likely to be judged more harshly for mistakes if they're in a job that's not normally associated with their gender. "The reason I got interested is, there was so much talk about race and gender barriers being broken," says Victoria Brescoll, a psychological scientist at Yale University and first author of the study. In the 2008 presidential election, ...

Manhattan, KS —December 7, 2010— We've all been there: we are watching a movie with a parent or relative when a steamy love scene appears. A new study published in Applied Cognitive Psychology shows that all of that squirming and averting of eyes is normal, especially when you are accompanied by your parents. The authors of the study assert that not all movie-watching experiences are enjoyable or positive. Some movies make us feel downright uncomfortable or disturbed in their content and delivery, while others are inspirational, touching, or have us rolling on the floor. ...

Questionnaire results and DNA samples volunteered by a group of University of Alberta students has broken new ground in the study of aggression. U of A Psychology researcher Peter Hurd was looking at the link between an individual's sensitivity to testosterone and aggressive behaviour. "I looked at the gene that makes the body's testosterone detector to determine if variations in this detector's sensitivity to the chemical causes people to be more or less aggressive," said Hurd. Hurd came across a previously published study in India that found violent criminals had ...

EAST LANSING, Mich. --- While Asian carp, gypsy moths and zebra mussels hog invasive-species headlines, many invisible invaders are altering ecosystems and flourishing outside of the limelight. A study by Elena Litchman, Michigan State University associate professor of ecology, sheds light on why invasive microbial invaders shouldn't be overlooked or underestimated. "Invasive microbes have many of the same traits as their larger, 'macro' counterparts and have the potential to significantly impact terrestrial and aquatic ecosystems," said Litchman, whose research appears ...

Athens, Ga. – Researchers at the University of Georgia have discovered a central switch that controls whether cells move or remain stationary. The misregulation of this switch may play a role in the increased movement of tumor cells and in the aggressiveness of tumors themselves. "Malignant cancer arises when cancer cells acquire the ability to move away from their primary tissue location," said Natalia Starostina assistant research scientist in the UGA department of cellular biology and lead author of the research. "The control of cell movement is a fundamental aspect ...

A new formulation of Amphotericin B (AmB) developed by University of British Columbia researchers has been shown to be stable in tropical climates and effective in treating Visceral Leishmaniasis (VL) in mouse models. VL is a blood-born parasitic disease that afflicts 12 million people worldwide, mainly in developing countries and tropical regions. According to the World Health Organization (WHO), 1.5 million new cases of the disease are reported every year, and 60,000 people die from it. AmB, a 50-year-old anti-fungal drug, is the standard treatment for VL, but its ...

(Garrison, NY) Practices for protecting human research subjects with Alzheimer's disease and other conditions that make them incapable of giving informed consent are widely variable and in need of more concrete ethical and legal guidance, according to a study in IRB: Ethics & Human Research. The findings are significant for several reasons. First of all, the authors write, many countries have made research on dementia a national health priority and launched clinical trials that involve people who are, or are likely to become, cognitively impaired. These trials increasingly ...

CHAMPAIGN, Ill. – The lame-duck Congress may be the last chance for the current Democratic majority to slip through legislation legalizing online gambling, a move that could have dire consequences for communities and the economy, a leading national gambling critic warns. Although much of the talk on Capitol Hill revolves around Bush-era tax cuts and reducing the deficit, University of Illinois business professor John W. Kindt says don't be surprised if a bill legalizing online gambling is floated by outgoing House Democrats under the auspices of revenue generation. "The ...

COLUMBUS, Ohio – Many U.S. restaurants may be ignoring a desire by American consumers to dine at environmentally friendly restaurants, according to a small exploratory study. Researchers found that more than 8 out of 10 restaurant patrons surveyed in Columbus said they would be willing to pay more to dine at "green" restaurants. More than 7 out of 10 said it was good for restaurants to protect the environment. The only problem is that very few restaurants market themselves as "green" or environmentally friendly, said Jay Kandampully, co-author of the study and professor ...

CINCINNATI—Helicopter emergency medical services can be a life saver for patients needing immediate care. But, according to a University of Cincinnati study, the process of activating them often delays treatment beyond recommended times. The study, published online ahead of print in Annals of Emergency Medicine, was led by assistant professor Jason McMullan, MD. In a multicenter, retrospective chart review, McMullan found that a majority of STEMI heart attack patients transferred by a hospital-based helicopter emergency medical service (HEMS) in 2007 did not receive treatment ...

System 94B has not been classified as a tropical depression, but NASA satellite data has shown that it is creating heavy rainfall near India's southeastern coast. A second NASA satellite revealed that strong wind shear is continuing to push convection to the northwest of System 94B's center of circulation. The Tropical Rainfall Measuring Mission (TRMM) satellite viewed an area of thunderstorms associated with System 94B near the east coast of India in the Bay of Bengal on December 7 at 0123 UTC. Data from TRMM's Precipitation Radar (PR) and Microwave Imager (TMI) showed ...

GREENBELT, Md. -- A new NASA computer modeling effort has found that additional growth of plants and trees in a world with doubled atmospheric carbon dioxide levels would create a new negative feedback – a cooling effect – in the Earth's climate system that could work to reduce future global warming. The cooling effect would be -0.3 degrees Celsius (C) (-0.5 Fahrenheit (F)) globally and -0.6 degrees C (-1.1 F) over land, compared to simulations where the feedback was not included, said Lahouari Bounoua, of Goddard Space Flight Center, Greenbelt, Md. Bounoua is lead author ...
