Bicycle infrastructure can reduce risk of cycling injuries by half: UBC study

2012-10-19
(Press-News.org) Certain types of routes carry much lower risk of injury for cyclists, according to a new University of British Columbia study on the eve of Vancouver's Bike to Work Week.

The study, published today in the American Journal of Public Health, analyzed the cause of 690 cycling injuries in Vancouver and Toronto from 2008 to 2009 and various route types and infrastructure.

The greatest risk to cyclists occurs when they share major streets with parked cars, with no bike lanes present – like on Broadway in Vancouver or Dundas Street in Toronto. Without a designated space on the road, cyclists face a heightened risk of injury from moving cars and car doors opening, according to the study.

In contrast, infrastructure designed for cyclists – including bike lanes on major streets without parked cars, residential street bike routes, and off-street bike paths – carries about half the risk, while cycle tracks (physically separated bike lanes) carries the lowest injury risk for cyclists, at about one-tenth the risk.

"Cycle tracks and other bike-specific infrastructure are prevalent in the cycling cities of Northern Europe, but have been slow to catch on in North America," says Kay Teschke, a professor in UBC's School of Population and Public Health and lead author of the study. "Adoption of safer route infrastructure would prevent crashes from occurring in the first place, while encouraging cycling. Since cycling offers major health benefits, this is a win-win."

Teschke says that increased injury risk also exists with streetcar or train tracks, and where there is construction. "There is renewed interest in streetcars for urban transportation, and the associated tracks were found to be particularly hazardous for cyclists," she adds. "There is also higher risk when construction impacts road traffic. Safe detours for cyclists need to be provided."

First-of-its-kind self-assembled nanoparticle for targeted and triggered thermo-chemotherapy

2012-10-19
Boston, MA— Excitement around the potential for targeted nanoparticles (NPs) that can be controlled by stimulus outside of the body for cancer therapy has been growing over the past few years. More specifically, there has been considerable attention around near-infrared (NIR) light as an ideal method to stimulate nanoparticles from outside the body. NIR is minimally absorbed by skin and tissue, has the ability to penetrate deep tissue in a noninvasive way and the energy from NIR light can be converted to heat by gold nanomaterials for effective thermal ablation of diseased ...

Conservation scientists look beyond greenbelts to connect wildlife sanctuaries
2012-10-19
We live in a human-dominated world. For many of our fellow creatures, this means a fragmented world, as human conduits to friends, family, and resources sever corridors that link the natural world. Our expanding web of highways, cities, and intensive agriculture traps many animals and plants in islands and cul-de-sacs of habitat, held back by barriers of geography or architecture from reaching mates, food, and wider resources. A team of researchers, managers, and ecological risk assessors review the current state-of-the-art in landscape connectivity planning, offering ...

Solar power is contagious

People are more likely to install a solar panel on their home if their neighbors have one, according to a Yale and New York University study in the journal Marketing Science. The researchers studied clusters of solar installations throughout California from January 2001 to December 2011 and found that residents of a particular zip code are more likely to install solar panels if they already exist in that zip code and on their street. "We looked at the influence that the number of cumulative adoptions—the number of people who already installed solar panels in a zip ...

Helmet-to-helmet collisions: Scientists model how vibrations from football hits wobble the brain

2012-10-19
It's fall football season, when fight songs and shouted play calls fill stadiums across the country. Another less rousing sound sometimes accompanies football games: the sharp crack of helmet-to-helmet collisions. Hard collisions can lead to player concussions, but the physics of how the impact of a helmet hit transfers to the brain are not well understood. A research team from the U.S. Naval Academy in Annapolis, Md., has created a simplified experimental model of the brain and skull inside a helmet during a helmet-to-helmet collision. The model illustrates how the fast ...

Dinosaur-era acoustics: Global warming may give oceans the 'sound' of the Cretaceous

2012-10-19
Global temperatures directly affect the acidity of the ocean, which in turn changes the acoustical properties of sea water. New research suggests that global warming may give Earth's oceans the same hi-fi sound qualities they had more than 100 million years ago, during the Age of the Dinosaurs. The reason for this surprising communication upgrade is that whales vocalize in the low-frequency sound range, typically less than 200 hertz, and the new research predicts that by the year 2100, global warming will acidify saltwater sufficiently to make low-frequency sound near ...

Short booms still annoying: Scientists study how mid-level noise bursts lasting less than a second affect the concentration of arithmetic-solving test subjects

2012-10-19
Noise can be distracting, especially to a person trying to concentrate on a difficult task. Studying annoying noises helps architects design better building environments and policy makers choose effective noise regulations. To better understand how short noise bursts affect humans' mental state, researchers from the University of Nebraska – Lincoln played quarter-second-long white noise clips to test subjects as they worked on arithmetic problems. The researchers noticed a slight general trend toward lower performance when louder noises were played, and also identified ...

Taking the bite out of baseball bats

2012-10-19
Miss hitting the "sweet spot" on a baseball bat and the resulting vibrations can zing your hands. Bat companies have tried for decades to reduce these painful shocks with limited success. But Daniel Russell, a professor in the graduate program in acoustics at Pennsylvania State University in University Park, has figured out that bat vibrations between 600 and 700 hertz (Hz) cause the most pain and that specifically tuned vibration absorbers are the best at combatting the sting. He will present the results of his damping technique comparisons at the 164th meeting of the ...

World's largest subwoofer: Earthquakes 'pump' ground to produce infrasound

2012-10-19
Earthquakes sway buildings, buckle terrain, and rumble – both audibly and in infrasound, frequencies below the threshold of human hearing. New computer modeling by a team of researchers indicates that most of the low-frequency infrasound comes from an unexpected source: the actual "pumping" of the Earth's surface. The researchers confirmed their models by studying data from an actual earthquake. "It's basically like a loudspeaker," said Stephen Arrowsmith, a researcher with the Geophysics Group at Los Alamos National Laboratory in Santa Fe, N.M., who presents his team's ...
