What actually causes aging?
August 1, 2015 06:57 AM - Northwestern University
When does aging really begin? Two Northwestern University scientists now have a molecular clue. In a study of the transparent roundworm C. elegans, they found that adult cells abruptly begin their downhill slide when an animal reaches reproductive maturity.
A genetic switch starts the aging process by turning off cell stress responses that protect the cell by keeping important proteins folded and functional. The switch is thrown by germline stem cells in early adulthood, after the animal starts to reproduce, ensuring its line will live on.
Ways to improve indoor air quality
July 25, 2015 07:17 AM - ClickGreen Staff, ClickGreen
Indoor air quality isn’t something most people think about, but breathing clean air can and does impact out health. Here’s why paying attention to the air you breathe indoors is so important and how to then go about improving it.
Vacuum More Often
Vacuuming more often will help keep dust at bay, but many vacuums also come with a filter system which can remove mold, pollen, and other air pollutants. Aim to vacuum at least once a week, twice if you live with animals.
Diesel exhaust found causing health hazards in EU cities
July 23, 2015 06:59 AM - EurActiv
The automotive industry needs to face up to the hazard to health posed by its diesel engines. That stark reality was brought home again to Europeans and, in particular, Londoners last week when Transport for London and the Greater London Authority revealed that an additional 5,900 early deaths annually in the EU’s largest city are attributable to long-term exposure to nitrogen dioxide (NO2), a toxic gas emitted in urban areas largely from diesel engines.
Concern about the health effects of NO2 is growing fast. The gas was known to irritate lungs and cause respiratory infections and asthma, including acute respiratory illnesses in children. It has also been linked to birth abnormalities. But this new research by King’s College London estimates for the first time the number of premature deaths caused. The study also shows an additional 3,500 deaths are caused by PM2.5, bringing the total number of people who die early because of air pollution annually in London to 9,400.
Do you always get sick when flying? Try Elderberries for some relief

The negative health effects of international air travel are well documented but now it seems that the common elderberry can provide some relief.
Disaster displacement on the rise
July 22, 2015 08:54 AM - ClickGreen Staff
In the last seven years, an estimated one person every second has been forced to flee their home by a natural disaster, with 19.3 million people forced to flee their homes in 2014 alone, according to a new report. The research suggests disaster displacement is on the rise, and as policy leaders worldwide advance towards the adoption of a post-2015 global agenda, the time has never been better to address it.
EPA Releases Updated Environmental and Public Health Indicators in Online Database
July 21, 2015 09:04 AM - USEPA Newsroom
The U.S. Environmental Protection Agency (EPA) released updated environmental and public health indicators in an online database, making information about the current and historical condition of the nation’s environment and human health more accessible to the public. This is an online update to EPA’s Report on the Environment. Users can explore 85 individual indicators-- on our air, water, land, human exposure, health and ecological condition-- using interactive graphs, tables, and maps, and download the data for each indicator.
Eruption of Bardarbunga volcano in Iceland and its impact on SO2 concentrations in Europe
July 20, 2015 02:36 PM - EUROPEAN ASSOCIATION OF GEOCHEMISTRY via EurekAlert.
The six month long eruption of the Bardarbunga volcano (31 August 2014?27 February 2015 ) was the largest in Iceland since the devastating Laki eruption of 1783-84, producing around 1.6 km3 of lava, covering an area equivalent to Manhattan Island.
The eruption caused total Sulphur dioxide (SO2) emissions of nearly 12m tonnes, which exceeded the total SO2 emitted in Europe in 2011. In Iceland, concentration of SO2 exceeded the 350 µg m-3 hourly average health limit over much of the country for days to weeks. However, the effects of the volcano were not confined to Iceland - many parts of Europe also saw high SO2 levels.
Researchers were initially concerned that the SO2 emissions would be much higher, which would have caused serious health problems throughout Iceland and perhaps Europe.
France estimates the economic costs of air pollution
July 16, 2015 06:40 AM - Editors EurActiv
The French Senate has called for new efforts to tackle air pollution, arguing it inflates healthcare costs, reduces economic productivity and agricultural yields, and has put Paris in the EU's bad books.
A Committee of Inquiry in the French Senate has described air pollution as an "economic aberration". The committee's proposals to reduce the phenomenon, which costs France over €100 billion every year, include raising the tax on diesel and taxing emissions of the worst polluting substances.
In the report entitled "Air pollution: the cost of inaction", published on Wednesday 15 July, the Senate committee estimated the annual cost of air Pollution in France at €101.3 billion.
Going to the beach may require hand sanitizer in addition to sunscreen
July 15, 2015 01:07 PM - American Chemical Society
“No swimming” signs have already popped up this summer along coastlines where fecal bacteria have invaded otherwise inviting waters. Some vacationers ignore the signs while others resign themselves to tanning and playing on the beach. But should those avoiding the water be wary of the sand, too? New research in the ACS journal Environmental Science & Technology investigates reasons why the answer could be “yes.” Sewage-contaminated coastal waters can lead to stomach aches, diarrhea and rashes for those who accidentally swallow harmful microbes or come into contact with them. But over the past decade, scientists have been finding fecal bacteria in beach sand at levels 10 to 100 times higher than in nearby seawater.
California towns getting water by truck as drought continues and wells run dry
July 11, 2015 07:04 AM -
Rural Tulare County, Calif., is now being called the epicenter of this drought.
That's because at least 1,300 residential wells have run dry, affecting at least 7,000 people. When your taps start spitting out air here, Paul Boyer and his team are who you call.
Under a punishing midafternoon sun, Boyer helps muscle down five of these hefty 400-pound water tanks from a semi-truck flatbed. He helps run a local nonprofit that's in charge of distributing these 2,500-gallon water tanks to drought victims.
