Detention basins could catch more than stormwater

Everywhere you go there are stormwater detention basins built near large construction projects intended to control the flow of rainwater and runoff. Now, those basins might help in controlling nitrogen runoff into rivers and lakes, according to Lauren E. McPhillips, assistant professor of civil and environmental engineering at Penn State.

Largest-ever study of coral communities unlocks global solution to save reefs

The largest study ever conducted of its kind has identified where and how to save coral reef communities in the Indo-Pacific, according to an international group of scientists from WCS (Wildlife Conservation Society) and other conservation NGOs, government agencies, and universities. The study outlines three viable strategies that can be quickly enacted to help save coral reefs that are threatened...

Ancient pigs endured a complete genomic turnover after they arrived in Europe

New research led by Oxford University and Queen Mary University of London has resolved a pig paradox. Archaeological evidence has shown that pigs were domesticated in the Near East and as such, modern pigs should resemble Near Eastern wild boar. They do not. Instead, the genetic signatures of modern European domestic pigs resemble European wild boar.

New study finds that race is a factor in investment judgments

According to new research released today in the Proceedings of the National Academy of Sciences, race influences the investment judgments of asset allocators. Experts believe this may contribute to the stark racial disparities in the world of institutional investing.

Mapping the effects of drought on vulnerable populations

The greater frequency of droughts, combined with underlying economic, social and environmental risks, means that dry spells have an increasingly destructive impact on vulnerable populations, and particularly on children in the developing world. In a new study by researchers from IIASA and the U.S., the team set out to map at-risk populations at the global scale.

Trump administration weakens endangered species law

US President Donald Trump's administration on Monday finalized rollbacks to key provisions of the Endangered Species Act, a law supported by a large majority of Americans and credited with saving the gray wolf, bald eagle and grizzly bear.

NASA measures rain rate in tiny Tropical Storm Henrietta

Tiny Tropical Storm Henrietta is the newest addition to the tropical cyclone line-up in the Eastern Pacific Ocean. The storm developed early on Aug. 12 and soon after the GPM satellite passed overhead and found heavy rain happening around its center.

Wildlife trafficking and more hinder nations' sustainable development

Transnational environmental crime—wildlife trafficking, illegal logging, dumping hazardous waste and more—takes an estimated $91 to $259 billion bite out of the global economy and has strong ties to organized crime finance, says a new study from Michigan State University and published in Nature Sustainability.

Artificial intelligence helps banana growers protect the world's favorite fruit

Artificial intelligence-powered tools are rapidly becoming more accessible, including for people in the more remote corners of the globe. This is good news for smallholder farmers, who can use handheld technologies to run their farms more efficiently, linking them to markets, extension workers, satellite images, and climate information. The technology is also becoming a first line of defense...

A new timeline of Earth's cataclysmic past

Welcome to the early solar system. Just after the planets formed more than 4.5 billion years ago, our cosmic neighborhood was a chaotic place. Waves of comets, asteroids and even proto-planets streamed toward the inner solar system, with some crashing into Earth on their way.

How do atoms vibrate in graphene nanostructures?

In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, opto- and quantum-technology it is crucial to understand how phonons—the vibration of atoms in solids—influence the materials' properties. Researchers from the University of Vienna, the Advanced Institute of Science and Technology in Japan, the company JEOL and La Sapienza University...
