Fruit and veg give you the feel-good factor
July 11, 2016 10:17 AM - University of Warwick via EurekAlert!

University of Warwick research indicates that eating more fruit and vegetables can substantially increase people's later happiness levels.

Published in the prestigious American Journal of Public Health, the study is one of the first major scientific attempts to explore psychological well-being beyond the traditional finding that fruit and vegetables can reduce risk of cancer and heart attacks.

Happiness benefits were detected for each extra daily portion of fruit and vegetables up to 8 portions per day.

Researchers assess heatwave risks associated with climate change
July 8, 2016 06:35 AM - IOP Publishing via EurekAlert!

Combining climate and mortality data, researchers have estimated that 315 deaths in Greater London and 735 deaths in Central Paris can be strongly linked to the 2003 heatwave that set record-breaking temperatures across Europe. Taking their analysis a step further, they determine that 64 (± 3) deaths from the London dataset and 506 (± 51) deaths from the Paris dataset are attributable to anthropogenic climate change, which increased the risk of heat related mortality by 20% and 70%, respectively, in the two cities. The team, led by scientists from the University of Oxford and Public Health England, has reported its latest findings in the journal Environmental Research Letters.

The Antarctic Ozone Hole May Be Closing
July 7, 2016 07:21 AM - s.e. smith

There’s good news from Antarctica, where researchers with tools like ozonesondes — pictured above — have been following the infamous ozone hole as it waxes and wanes over the seasons. The ozone hole has shrunk by 1.5 million square miles – around 4 million square kilometers — and this “healing” trend appears to be continuing.

A major ecological catastrophe has been averted, and we can cite human intervention as the reason. When the globe swept into action with 1987′s Montreal Protocol, which banned a number of substances known to contribute to ozone depletion, it apparently worked.

When scientists first began to observe a hole in the ozone layer over Antarctica, it was a cause for grave concern. Though ozone levels actually fluctuate throughout the year, they perform an important function by blocking the sun’s harmful UV radiation.

Paris bans old cars on weekdays
July 3, 2016 08:29 AM - ELEANOR BEARDSLEY, NPR

Paris was at the forefront of public bike-sharing schemes, and it now has electric car-sharing schemes and is something of a laboratory for mobility. As of today, motorists with cars built before 1997, and motorcycles built before 2000, will no longer be able to drive them in the city during daylight hours on weekdays.

Paris Mayor Anne Hidalgo says keeping old cars out of the city will help lower pollution levels. But not everyone is happy about it.

Marc Vernhet makes his living driving tourists around Paris in the classic French car known as the Deux Chevaux, or two-horse power. Peugeot Citroen no longer makes the model, but for collectors, it's a nostalgic symbol of the good old days. Vernhet says tourists from all over the world want to ride in them.

 

Scientists observe first signs of healing in the Antarctic ozone layer
June 30, 2016 03:47 PM - Massachusetts Institute of Technology via EurekAlert!

Scientists at MIT and elsewhere have identified the "first fingerprints of healing" of the Antarctic ozone layer, published today in the journal Science.

The team found that the September ozone hole has shrunk by more than 4 million square kilometers -- about half the area of the contiguous United States -- since 2000, when ozone depletion was at its peak. The team also showed for the first time that this recovery has slowed somewhat at times, due to the effects of volcanic eruptions from year to year. Overall, however, the ozone hole appears to be on a healing path.

The authors used "fingerprints" of the ozone changes with season and altitude to attribute the ozone's recovery to the continuing decline of atmospheric chlorine originating from chlorofluorocarbons (CFCs). These chemical compounds were once emitted by dry cleaning processes, old refrigerators, and aerosols such as hairspray. In 1987, virtually every country in the world signed on to the Montreal Protocol in a concerted effort to ban the use of CFCs and repair the ozone hole.

An ingredient in your sunscreen can be killing sharks
June 30, 2016 06:51 AM - Natalia Lima, Care2

Most animal lovers wouldn’t dream of harming an animal for fashion. Fur? No, thank you. Leather? I don’t think so. Yet they might be unknowingly killing sharks — and highly endangered kinds on top of that — for their beauty routine.

Unbeknownst to most, one little ingredient in products like sunscreens, moisturizing lotions, lip balms, lipsticks and face creams is responsible for the death of over three million sharks annually.

 

Vermont will be the first US State to Label GMOs
June 30, 2016 06:40 AM - Gina-Marie Cheeseman , Triple Pundit

Vermont will soon be the first state in the nation to require labels on genetically modified (GMO) foods. Its GMO-labeling law, the first passed in the nation, goes into effect on July 1. Maine and Connecticut have since passed their own GMO-labeling laws. But they won’t go into effect until neighboring states pass similar legislation.

Saved by the sun
June 29, 2016 12:21 PM - University of Alberta via EurekAlert!

A new twist on the use of renewable energy is saving children's lives in Africa. The innovation--a solar powered oxygen delivery system--is providing concentrated oxygen in hospital for children suffering from severe pneumonia.

The device created by Dr. Michael Hawkes, an assistant professor in the University of Alberta's Division of Pediatric Infectious Diseases, is the focus of a recently published study in The International Journal of Tuberculosis and Lung Disease and is already in use in two hospitals in Uganda.

"Solar-powered oxygen is using freely available resources--the sun and air--to treat children with pneumonia in the most remote settings," says Hawkes. "It's very gratifying for a pediatrician doing research in a lower-resource setting to fill a clinical gap and save lives. It's what our work is all about."

Household fuels exceed power plants and cars as source of smog in Beijing
June 27, 2016 03:40 PM - Princeton University via EurekAlert!

Beijing and surrounding areas of China often suffer from choking smog. The Chinese government has made commitments to improving air quality and has achieved notable results in reducing emissions from the power and transportation sectors. However, new research indicates that the government could achieve dramatic air quality improvements with more attention on an overlooked source of outdoor pollution -- residential cooking and heating.

"Coal and other dirty solid fuels are frequently used in homes for cooking and heating," said Denise Mauzerall, a professor of civil and environmental engineering and public and international affairs at Princeton University. "Because these emissions are essentially uncontrolled they emit a disproportionately large amount of air pollutants which contribute substantially to smog in Beijing and surrounding regions."
