A Recipe For Concrete That Can Withstand Road Salt Deterioration
May 18, 2017 12:35 PM - Drexel University

Road salt, used in copious helpings each winter to protect them from ice and preserve safe driving conditions, is slowly degrading the concrete they’re made of. Engineers have known for some time that calcium chloride salt, commonly used as deicer, reacts with the calcium hydroxide in concrete to form a chemical byproduct that causes roadways to crumble.

Polluted air can generate power
May 8, 2017 06:35 AM - KU Leuven

Researchers from the University of Antwerp and KU Leuven have succeeded in developing a process that purifies air and, at the same time, generates power. The device must only be exposed to light in order to function.

Leaf litter has slower decomposition rate in warm temperatures than previously thought
May 8, 2017 06:30 AM - Kansas State University

The time it takes for a leaf to decompose might be the key to understanding how temperature affects ecosystems, according to Kansas State University ecologists. 

Not even the Himalayas are immune to traffic smog

Smog from cars and trucks is an expected health hazard in big cities, but researchers from the University of Cincinnati found pollution from truck exhaust on one of the most remote mountain roads in the world.
 

Flexible, organic and biodegradable: Stanford researchers develop new wave of electronics
May 2, 2017 09:48 PM - Sarah Derouin, Stanford University

As electronics become increasingly pervasive in our lives – from smart phones to wearable sensors – so too does the ever rising amount of electronic waste they create. A United Nations Environment Program report found that almost 50 million tons of electronic waste were thrown out in 2017—more than 20 percent higher than waste in 2015. Troubled by this mounting waste, Stanford engineer Zhenan Bao and her team are rethinking electronics. “In my group, we have been trying to mimic the function of human skin to think about how to develop future electronic devices,” Bao said. She described how skin is stretchable, self-healable and also biodegradable – an attractive list of characteristics for electronics. “We have achieved the first two [flexible and self-healing], so the biodegradability was something we wanted to tackle.”

Global Warming Making Oceans More Toxic, Research Shows
April 25, 2017 07:15 AM - Stony Brook University

Ocean warming since the 1980s is linked to the spread of toxic algae, according to a newly published study led by Dr. Christopher Gobler, marine science professor in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University.

El NiƱo Shifts Geographic Distribution of Cholera Cases in Africa
April 12, 2017 06:55 AM - Johns Hopkins Bloomberg School of Public Health

Cholera cases in East Africa increase by roughly 50,000 during El Niño, the cyclical weather occurrence that profoundly changes global weather patterns, new Johns Hopkins Bloomberg School of Public Health research suggests.

The findings, researchers say, could help health ministries anticipate future cholera surges during El Niño years and save lives.

Earth's first example of recycling -- its own crust!
March 17, 2017 07:22 AM - Carnegie Institute for Science

Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from Carnegie’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. Their work is published by Science.  

Eating healthier food could reduce greenhouse gas emissions
March 16, 2017 06:59 AM - Julie Cohen, UC Santa Barbara

You are what you eat, as the saying goes, and while good dietary choices boost your own health, they also could improve the health care system and even benefit the planet. Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care. As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.

What makes farmers try new practices?
March 15, 2017 07:27 AM - University of Illinois at Urbana-Champaign

Change is never easy. But when it comes to adopting new agricultural practices, some farmers are easier to convince than others.
