Statistics help clear fog for better climate change picture

Researchers are using statistical approaches to analyze climate change risks, including the Atlantic Meridional Overturning Circulation. Bayesian statistics is a key tool in quantifying uncertainty and predicting future events. Collaboration between disciplines is essential for advancing climate science and risk management.

Decoys could blunt spread of ash-killing beetles

Researchers create female emerald ash borer decoy using polymers, allowing for more efficient trapping and detection of male beetles. The decoy is 40% more effective than previously used methods, paving the way for swift control of the pest.

Flu outbreaks modeled by new study of classroom schedules

Researchers at Penn State University have developed a method to determine how to focus disease-control strategies based on individuals most likely to spread the infection. By analyzing classroom schedules and human-networking theory, they created a low-cost but effective way to predict disease outbreaks in closed groups.

Preserving biodiversity can be compatible with intensive agriculture

A new study by Karl Zimmerer and colleagues found that small-scale farmers in Bolivia, Peru, and Mexico can successfully cultivate genetically diverse local crops alongside intensive agriculture. These farms often rely on remittances from migrant communities, which enables them to maintain agrobiodiversity maize.

Ozone depletion trumps greenhouse gas increase in jet-stream shift

A new study reveals that ozone depletion has a greater impact on the jet stream's southward shift than increasing greenhouse gases. Researchers analyzed wind patterns over a 10-day period and found that ozone depletion was associated with a poleward shift of westerlies, while greenhouse gases were linked to an equatorward shift.

Portrayal of spring break excess may be stereotypes gone wild

Researchers analyzed studies on spring break from 1980 to 2010 and found no conclusive evidence of increased extreme behaviors. Instead, they suggest that campus behaviors are a good predictor of how students will act during spring break. The media portrayal of spring break may not accurately represent the full experience.

Diet may not impact certain health outcomes in older persons

Researchers found no link between dietary patterns and cardiovascular disease, diabetes, or metabolic syndrome in older adults. However, a Western diet was associated with an increased risk of hypertension. The study suggests that overly restrictive diets may not be beneficial for older adults.

Protective communities may reduce risk of drinking in teens

Researchers found that living in a caring community can help curb teenage alcohol use, while hanging out with antisocial peers can increase the risk. The study analyzed over 200,000 students and discovered that individual, family, and peer risk factors as well as community protective factors moderately predicted alcohol use.

Weight counseling decreases despite rise in obesity

Despite a significant increase in overweight and obese Americans, primary care physicians have decreased weight counseling services, especially for patients with high blood pressure and diabetes. In 2007-2008, only 6.2% of visits included weight counseling, a decline from 1995.

A New Year's gift from NASA and Penn State

Astronomers from NASA's Goddard Space Flight Center and Penn State have released a vast image gallery featuring ultraviolet and optical images captured by the Swift satellite's Ultraviolet/Optical Telescope. The collection includes early images, stunning views of galaxies, and rare types of stars.

Fluctuating environment may have driven human evolution

Researchers found that the environment transitioned rapidly between a closed woodland and an open grassland, triggering evolutionary changes. The team used lake sediments and biomarkers to reconstruct the types of vegetation present, revealing a correlation between environmental changes and planetary movement.

Spread of cancer cells may be slowed by targeting of protein

Researchers at Penn State College of Medicine found that targeting km23-1, a motor protein involved in cell migration, can slow the spread of cancer cells. By inhibiting km23-1, cancer therapies may be developed to prevent tumor cells from migrating to other parts of the body.

Plant sniffs out danger to prepare defenses against pesky insect

Researchers at Penn State discovered that plants can detect and respond to insect odors, leading to improved defenses. The tall goldenrod plant's ability to sense the sex attractant emitted by male flies makes it less appealing to female flies, reducing damage and increasing seed quality.
