People riding free-floating bike share rentals in Seattle are wearing helmets infrequently, according to a new analysis conducted by University of Washington researchers. Only 20 percent of bike share riders wore helmets in the study, while more than 90 percent of cyclists wore helmets while riding their own bikes. Different research on the free-floating bike share systems showed that bikes were usually available in all Seattle neighborhoods across economic, racial and ethnic lines. However, more bikes were located in more-advantaged neighborhoods.
More than half of people who take medical cannabis for chronic pain say they've driven under the influence of cannabis within two hours of using it, at least once in the last six months, according to a new survey. One in five of them said they'd driven while 'very high' in the past six months.
Of the known alien (non-native) species found in Antarctica, a non-biting species of midge currently presents one of the highest risks to terrestrial ecosystems, researchers have found.
Wild animals are increasingly exploited for entertainment and photo opportunities. A new study highlights that tourists in Morocco object to the use of barbary macaques as photo props, raising concerns about the animal's welfare and risk to human health. The findings are presented today at the British Ecological Society annual conference in Birmingham.
Approximately one-third of all US-born US citizens living in the US are considering leaving to live abroad. Drawing on data collected in 2014, researchers Dr. Amanda Klekowski von Koppenfels from the University of Kent's Brussels School of International Studies, and Dr. Helen Marrow of Tufts University, USA, identified the reasons for this as: exploration (87.4 percent); retirement (50.8 percent); leaving a bad or disappointing situation in the US (49.0 percent); and working (48.3 percent).
Researchers say that changing the legal drink-driving limit without enhancing enforcement and sufficiently publicizing the change does not reduce road traffic accidents.
The number of middle-aged Australian men who cycle on weekends has doubled in recent years, but the rise of the so-called 'Mamils' (middle aged men in lyrca) is confined to men in more affluent suburbs, says research in today's Medical Journal of Australia.
According to the latest World Health Organization (WHO) report on road safety, more than 1.3 million people die on the world's roadways each year -- and millions more are injured or disabled.
Laws to ban or curb drivers' use of cell phones and other handheld devices have greatly reduced the rate of fatalities for motorcyclists, according to a new study from Florida Atlantic University and the University of Miami. Results show that states with moderate to strong bans have motorcycle fatality rates that differ by as much as 11 percent compared to states with no bans.
Hydrogen-powered vehicles emit only water vapor from their tailpipes, offering a cleaner alternative to fossil-fuel-based transportation. But for hydrogen cars to become mainstream, scientists need to develop more efficient hydrogen-storage systems. Now, researchers reporting in ACS' Chemistry of Materials have used metal-organic frameworks (MOFs) to set a new record for hydrogen storage capacity under normal operating conditions.
