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.
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.
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 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.
Researchers use a NASA WB-57 research jet to examine icy cirrus clouds, aiming to understand their warming and cooling effects on Earth's climate. The Middle Latitude Cirrus Experiment gathers detailed information to improve computer simulations of future climate change.
An educational program tailored to individual needs improved safety behaviors among older drivers, but had no effect on collision rates. The program focused on visual deficits and strategies to avoid challenging driving situations.
The world has sped up over the last few years, with scientists noting no need for a leap second in five years. Tom O'Brian suggests changes in the Earth's core, ocean tides, and weather may be affecting its rotation. Most scientists expect the Earth to continue slowing down again in the future.
The AMPS system uses a tailored computer model, Polar MM5, to provide detailed forecasts for the extreme polar environment. Meteorologists have successfully used AMPS in emergency rescues from Antarctica since 2001, including a recent medical evacuation and ship rescue.
Researchers collected and analyzed a record-breaking ice core in the St. Elias range, providing insights into the North Pacific Decadal Oscillation (PDO). The PDO is a 20-30 year climate cycle affecting weather across North America, with cool and warm phases centered in the North Pacific.
Large planetary waves in the atmosphere led to a smaller Antarctic ozone hole in 2002. However, scientists emphasize that these weather patterns do not indicate the ozone layer is recovering and may return to previous sizes next year.
Trawler fishermen face unique occupational and weather-related hazards, while economic pressures often hinder safety measures. New technology can improve vessel buoyancy and provide access to reliable weather predictions.
Researchers analyzed daily weather and mortality data for 11 eastern US cities, finding that mortality risk increased with temperature extremes. Cities in the North were more sensitive to heat, while Southern cities were more vulnerable to cold temperatures.
A recent study by NASA researchers analyzed global weather stations and satellite observations to identify minimal local human influence. They found larger warming at urban stations on average, but used rural stations to adjust the records for a more accurate climate change measure.
Researchers analyzed lake sediment samples to find two naturally occurring warm periods in Alaska spanning 2,000 years. The initial period occurred from A.D. 0-300 and was accompanied by drier conditions; the second period corresponded to the Medieval Climatic Anomaly, a global warming event.
Researchers have found detectable levels of tributyltin in Gulf oysters, which can be toxic to crustaceans. Additionally, the Mississippi River has shown improvement in water quality, with a decrease in volatile organic compounds detected since 20 years ago.
A University of North Carolina at Chapel Hill study highlights the dangers of heatstroke in football and recommends shorter practices, non-contact drills, and regular cooling breaks. Coaches are urged to prioritize player safety and prevent tragedies.
