Green infrastructure provides benefits that residents are willing to work for, study shows

Urban areas face increasing problems with stormwater management. Impervious surfaces on roads and buildings cause flooding, which impacts the water quality of streams, rivers and lakes. Green infrastructure, including features such as rain barrels, green roofs, rain gardens, and on-site water treatment, can provide affordable and environmentally sound ways to manage precipitation.

Death toll rises as public health officials work to combat coronavirus

Days after the World Health Organization (WHO) declared a global public health emergency due to the rapid spread of the novel coronavirus, the number of confirmed cases continued to climb.The virus, which was first detected in the Chinese province of Hubei on Dec. 31, 2019, and has shut down the metropolis of Wuhan where more than 11 million reside, has infected over 17,000 in China, and killed...

Researchers find clues to how hazardous space radiation begins

Scientists at the University of New Hampshire have unlocked one of the mysteries of how particles from flares on the sun accumulate at early stages in the energization of hazardous radiation that is harmful to astronauts, satellites and electronic equipment in space. Using data obtained by NASA's Parker Solar Probe (PSP), researchers observed one of the largest events so far during the mission....

Team identifies low-energy solar particles from beyond Earth near the Sun

Using data from NASA's Parker Solar Probe (PSP), a team led by Southwest Research Institute identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. PSP is venturing closer to the Sun than any previous probe, carrying hardware SwRI helped develop. Scientists are probing the enigmatic features of the Sun to answer many...

Australia's orroral valley fire consumes over 155,000 acres in a week

NASA's Terra satellite saw yet another fire, known as the Orroral Valley Fire, break out in the Canberra region of Australia, specifically in and around the ?Namadgi National Park. In one week, these fires have consumed 62,988 hectares (155,646 acres) according to the Australian Capital Territory Emergency Services Agency as of Feb. 04, 2020 (2:30 am local Australian time). The Department of...

Making high-temperature superconductivity disappear to understand its origin

When there are several processes going on at once, establishing cause-and-effect relationships is difficult. This scenario holds true for a class of high-temperature superconductors known as the cuprates. Discovered nearly 35 years ago, these copper-oxygen compounds can conduct electricity without resistance under certain conditions. They must be chemically modified ("doped") with additional atoms...

Finding the source of chemical reactions

Scientists are constantly searching for the source of things like the origin of the universe, matter or life. Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory, in a collaboration with the Massachusetts Institute of Technology (MIT) and several other universities, have demonstrated a way to experimentally detect the most hidden aspect of all chemical reactions—the...
