Filtration Systems on School Buses Are Needed to Protect Children from Pollutants
March 2, 2015 02:56 PM - UCLA Newsroom
An on-board air filtration system developed specifically for school buses reduces exposure to vehicular pollutants by up to 88 percent, according to a study by researchers at the UCLA Fielding School of Public Health. The high-efficiency cabin air, or HECA, system could help protect the 25 million American children who commute on school buses nearly every day. Children are more susceptible to air pollution than adults because they breathe more quickly and their immune and cardiovascular systems are still developing, said Yifang Zhu, the study’s senior author and an associate professor in the department of environmental health sciences.
The miracle drink: Coffee!
February 27, 2015 07:56 AM - AMERICAN ACADEMY OF NEUROLOGY via EurekAlert
Drinking coffee may be associated with a lower risk of developing multiple sclerosis (MS), according to a study released today that will be presented at the American Academy of Neurology's 67th Annual Meeting in Washington, DC, April 18 to 25, 2015.
"Caffeine intake has been associated with a reduced risk of Parkinson's and Alzheimer's diseases, and our study shows that coffee intake may also protect against MS, supporting the idea that the drug may have protective effects for the brain," said study author Ellen Mowry, MD, MCR, with Johns Hopkins University School of Medicine in Baltimore and a member of the American Academy of Neurology.
Agricultural insecticides pose a global risk to surface water bodies
February 25, 2015 01:51 PM - Tilo Arnhold, Helmholtz Centre for Environmental Research
Streams within approximately 40% of the global land surface are at risk from the application of insecticides. These were the results from the first global map to be modeled on insecticide runoff to surface waters, which has just been published in the journal Environmental Pollution by researchers from the Helmholtz Center for Environmental Research (UFZ) and the University of Koblenz-Landau together with the University of Milan, Aarhus University and Aachen University. According to the publication, particularly streams in the Mediterranean, the USA, Central America and Southeast Asia are at risk.
Lash Length Keeps Eyes Healthy
February 25, 2015 09:03 AM - Georgia Tech
It started with a trip to the basement of the American Museum of Natural History in New York to inspect preserved animal hides. Later, Georgia Institute of Technology researchers built a wind tunnel about 2 feet tall, complete with a makeshift eye. By putting both steps together, the team discovered that 22 species of mammals – from humans, to hedgehogs, to giraffes – are the same: their eyelash length is one-third the width of their eye. Anything shorter or longer, including the fake eyelashes that are popular in Hollywood and make-up aisles, increases airflow around the eye and leads to more dust hitting the surface.
Risk of death from smoking higher than thought
February 24, 2015 06:57 AM - SAX INSTITUTE via EurekAlert
A large Australian study of more than 200,000 people has provided independent confirmation that up to two in every three smokers will die from their habit if they continue to smoke.
The research, published today in the international journal BMC Medicine, is the first evidence from a broad cross-section of the population to show the smoking-related death toll is as high as two thirds.

We need to focus on health and well-being, not economic growth
February 22, 2015 08:02 AM - Jules Pretty, Ecologist
The financial cost of the diseases of modern civilization is almost double the budget of the National Health Service, writes Jules Pretty, while the economy has grown past the point of greatest satisfaction. Our over-riding priority should be to move to greener, healthier, more sustainable and satisfying ways of life.
A substantial financial dividend could be released by a greener and healthier economy. Instead of encouraging material growth and consumption, we should consume in a way that is environmentally sustainable.
Component in olive oil kills cancer cells
February 16, 2015 08:52 AM - Rutgers University
A Rutgers nutritional scientist and two cancer biologists at New York City’s Hunter College have found that an ingredient in extra-virgin olive oil kills a variety of human cancer cells without harming healthy cells.
The ingredient is oleocanthal, a compound that ruptures a part of the cancerous cell, releasing enzymes that cause cell death.
Paul Breslin, professor of nutritional sciences in the School of Environmental and Biological Sciences, and David Foster and Onica LeGendre of Hunter College, report that oleocanthal kills cancerous cells in the laboratory by rupturing vesicles that store the cell’s waste.
Beavers provide insight on how to improve our enamel
February 13, 2015 09:50 AM - Northwestern University
Beavers don’t brush their teeth, and they don’t drink fluoridated water, but a new Northwestern University study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron. This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride. This discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.
When you stop at a red light you are exposed to higher levels of air pollution
February 13, 2015 08:36 AM - University of Surrey via EurekAlert.
UK commuters spend an average of about 1.5 hours a day at the wheel. Road vehicles in particular are known to emit polluting nanoparticles which contribute to respiratory and heart diseases. Now, researchers at the University of Surrey have found that where drivers spend just 2% of their journey time passing through traffic intersections managed by lights, this short duration contributes to about 25% of total exposure to these harmful particles.
The team monitored drivers' exposure to air pollutants at various points of a journey. Signalised traffic intersections were found to be high pollution hot-spots due to the frequent changes in driving conditions.
