Sooner than it takes to build a nuclear power station, lithium-air batteries could be helping wind and solar to make coal, oil and nuclear obsolete, say Cambridge scientists. Five times lighter and five times cheaper than current lithium batteries, Li-air would open the way to our 100% renewable future.

How to Eat and Stay Healthy this Holiday Season
When it comes to maintaining healthy lifestyles, people tend to fall off the wagon from Thanksgiving through New Year’s Day. Then, they set “get in shape” and “lose weight” as New Year’s resolutions. That’s not the best idea, says Charlotte Markey, a Rutgers University-Camden psychologist who teaches a course titled “The Psychology of Eating” and studies eating behaviors, body image and weight management. Overeating during the holidays, she notes, is not a matter of if, but when. People need to approach their goals in a smarter way.
Rutgers Today spoke with Markey, the author of Smart People Don’t Diet: How the Latest Science Can Help You Lose Weight Permanently, about a more realistic and sustainable strategy to losing weight and living healthier.
Sea traffic linked to hazardous levels of nanoparticles along coastlines
The air along coastlines is being heavily polluted by hazardous levels of nanoparticles from sea traffic, a new study has found.
Almost half of the measured particles stem from sea traffic emissions, while the rest is deemed to be mainly from cars but also biomass combustion, industries and natural particles from the sea.
"This is the first time an attempt has been made to estimate the proportion of nanoparticles stemming from sea traffic. The different types of nanoparticles have previously not been distinguished, but this new method makes it possible", says Adam Kristensson, researcher in Aerosol Technology at the Lund University Faculty of Engineering in Sweden.
Tourists may bring more home than just souvenirs
Invasive species are great hitchhikers. They float in the ballast of ships, lurk in luggage, stick to unwashed sports gear, and cling to the soles of hiking boots. Scientists focus on stopping them from spreading because, once a new species gets rooted, it is expensive to manage and nearly impossible to remove.
Shipping and industry are the major pathways for invasive species, but studies have also shown that tourists can spread them into protected wilderness.
Los ataques ParÃs, las negociaciones de clima y la guerra contra el terror
¿Es una coincidencia que el atentado terrorista de París se haya cometido semanas antes del COP21, la mayor conferencia sobre el clima desde el año 2009? Tal vez, escribe Oliver Tickell. Pero el fracaso en alcanzar un acuerdo climático fuerte parece ahora más probable. Y eso es un resultado que le gustaría al Estado Islámico (EI), que gana $ 500 millones al año por la venta de petróleo, junto con otros productores de petróleo.
Sushi or Ice Cream, which raises blood sugar more?
Which is more likely to raise blood sugar levels: Sushi or ice cream? According to a new Israeli study, the answer varies from one person to another. The study, which continuously monitored blood sugar levels in 800 people for a week, revealed that the bodily response to similar foods was highly individual.
The study, called the Personalized Nutrition Project, was led by Prof. Eran Segal and Dr. Eran Elinav of the Weizmann Institute. It was published in the November 19 issue of the scientific journal Cell, and has since stirred up the medical community, which might have to rethink dietary recommendations.
