Modified soybeans yield more in future climate conditions

By 2050, we will need to feed 2 billion more people on less land. Meanwhile, carbon dioxide levels are predicted to hit 600 parts per million—a 50% increase over today’s levels—and 2050 temperatures are expected to frequently match the top 5% hottest days from 1950-1979. In a three-year field study, researchers proved engineered soybeans yield more than conventional soybeans in 2050’s predicted climatic conditions.

Study measures air pollution increase attributable to air conditioning

When summer temperatures rise and people turn to their air conditioners to stay cool, something else also increases: air pollution.

A new study published Wednesday (May 3, 2017) in the journal Environmental Science & Technology shows that the electricity production associated with air conditioning causes emissions of sulfur dioxide, nitrogen oxides and carbon dioxide to increase by hundreds to thousands of metric tons, or 3 to 4 percent per degree Celsius (or 1.8 degrees Fahrenheit).

Turning chicken poop and weeds into biofuel

Chicken is a favorite, inexpensive meat across the globe. But the bird’s popularity results in a lot of waste that can pollute soil and water. One strategy for dealing with poultry poop is to turn it into biofuel, and now scientists have developed a way to do this by mixing the waste with another environmental scourge, an invasive weed that is affecting agriculture in Africa. They report their approach in ACS’ journal Energy & Fuels.

Cost of Zika Outbreak in the United States Could Be High

Even a relatively mild Zika outbreak in the United States could cost more than $183 million in medical costs and productivity losses, suggests a computational analysis led by Johns Hopkins Bloomberg School of Public Health researchers, while a more severe one could result in $1.2 billion or more in medical costs and productivity losses.

University of Saskatchewan project will use biowaste technology to clean up polluted soil

Soil scientists Derek Peak and Steven Siciliano and Northern Alberta Institute of Technology (NAIT) professor Paolo Mussone will work with industry partners Federated Cooperatives Limited (FCL) and United Farmers of Alberta Co-operative Limited (UFA) to develop and test new soil additives that can trap and remove petroleum hydrocarbons for easier digestion by soil-based organisms.

Wildlife Recovery Following the Exxon Valdez Oil Spill was Highly Variable Across Species

Thanks to a quarter-century of research and monitoring, scientists now know how different wildlife species were injured by the 1989 Exxon Valdez oil spill and how long it took for populations to recover.

This information may have important implications when responding to other oil spills, when conducting damage assessment studies after spills and when considering the environmental risks associated with extracting and shipping oil.

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

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.”

Some – But Not All – Corals Adapting to Warming Climate

A new WCS study reveals evidence that some corals are adapting to warming ocean waters – potentially good news in the face of recent reports of global coral die offs due to extreme warm temperatures in 2016. The study appears in the latest issue of Marine Ecology Progress Series.

The study looked at responses to extreme temperature exposures in the same reefs over time, and found less coral bleaching in 11 of the 21 coral species studied. WCS Senior Conservation Zoologist Tim McClanahan, who has been studying coral responses to climate change since the extreme temperatures of the1998 El Nino, authored the study.
