A new study by NCAR and CSU finds that unusually sunny weather contributed to last summer's record loss of Arctic sea ice. The research suggests that warmth from the Sun will increasingly affect Arctic sea ice loss in the summer.
Researchers at Indiana University School of Medicine found that introducing a relationship-centered learning environment improved student satisfaction with their medical education, with increased rates of out-of-state applications. The study also showed enhanced responsiveness to student problems and a more favorable impact on organiza...
A study of female red squirrels found that those born into favorable circumstances with abundant food, warmer spring weather, and lower population experienced increased reproductive success and longevity. In contrast, those born into harsher conditions struggled to reproduce and lived shorter lives.
Research published in Occupational and Environmental Medicine suggests that high temperatures increase the risk of cardiovascular death from heart disease or stroke. Ozone levels are a common link between temperature fluctuations, with higher ozone levels associated with increased cardiovascular mortality.
Researchers discovered a clear preference for pink or reddish hues among women, shifting their color preference towards red and away from blue. The study suggests that this difference may be driven by biological factors, potentially related to evolution and the importance of ripe fruit in hunter-gatherer societies.
The National Center for Atmospheric Research has developed an enhanced in-flight icing product to guide aircraft around hazardous icing conditions. This new system rates areas by icing severity and probability of encounters, helping reduce flight delays and fuel costs.
Research published in Heart reveals high humidity increases heart attack deaths among the elderly in Athens. Average monthly humidity was the single most important factor influencing average monthly death rates from heart attack in those over 70.
A team of Iowa State University engineers is creating a network of wireless sensors to detect suspicious activity on the nation's power transmission system. The system could quickly locate breakdowns and severe weather damage, allowing power companies to prevent blackouts and respond more effectively.
Researchers studied polar motion over three and a half months, finding small loops up to a cell phone size due to weather patterns and oceanic influences. The study demonstrates day-to-day changes in atmospheric pressure affect Earth's rotation for the first time.
Researchers found that gray-cheeked mangabeys revisit fig trees after warm and sunny days, rather than after cold and cloudy days. This suggests monkeys use past weather conditions to inform their foraging decisions.
The year 2005 may have been the warmest year in a century, with global temperatures returning to levels seen in 1998. The Earth has warmed by 0.6° C or 1.08° F over the past 30 years and 0.8° C or 1.44° F over the past 100 years.
A recent study found that darkness more than triples the risk of fatalities in EMS helicopter crashes, while bad weather increases the risk eight-fold. The study suggests that helicopter EMS programs should prioritize patient safety and transport patients by air only when the benefits clearly outweigh the risks.
Researchers Anick Bosmans and Hans Baumgartner found that consumers rely on specific extraneous emotions when evaluating products. They discovered two types of emotions: achievement (cheerfulness/dejection) and protection (quiescence/agitation), which influence product evaluations differently.
A study by Yale University and NOAA finds that direct sunlight affects weather balloon temperature probes, leading to discrepancies in global warming estimates. This correction reveals an increase of 0.2 degrees Celsius per decade in average global temperature over the last thirty years.
NASA has postponed a scheduled satellite launch at Vandenberg Air Force Base in California. The launch, originally set for May 12, will now take place pending favorable weather conditions. NASA TV coverage is available online and via satellite.
