Before Hurricane Gert became a post-tropical cyclone, NASA got a look at the rainfall occurring within the storm. After Gert became post-tropical NOAA’s GOES-East satellite captured an image as Gert was merging with another system.
The Global Precipitation Measurement mission or GPM core observatory satellite provided rainfall information on Hurricane Gert on August 16, 2017 at 5:37 p.m. EDT (2137 UTC). At that time, Gert was a strong category two hurricane with maximum sustained winds of about 93.5 mph (85 knots).

Climate change and habitat conversion to agriculture are working together to homogenize nature, indicates a study in the journal Global Change Biology led by the University of California, Davis.
In other words, the more things change, the more they are the same.
While the individual impacts of climate change and habitat conversion on wildlife are well-recognized, little is known about how species respond to both stressors at once.

New technologies for analyzing DNA may transform how imperiled species are considered and managed for conservation protection, according to a study published today in the journal Science Advances and led by the University of California, Davis.
These technologies can be applied to a wide range of species around the world — from mushrooms to walruses — but the study focuses on two iconic species of Pacific salmon: steelhead and chinook. While steelhead are a legendary sport fish, chinook are considered the workhorse of the West Coast salmon industry.

The coming decade may determine whether humanity will set a course toward a more socially and ecologically sustainable society. A crucial part of this goal is to develop a better understanding of how cooperation can be improved and become more effective, both within and among private stakeholders and public institutions.
“Collaborative governance is often highlighted as a solution to different environmental problems. For example, when small-scale fishermen agree to avoid overfishing or when states agree to reduce greenhouse gases. But we don’t know so much about how cooperation around environmental issues works in a complex world. Different actors want different things, different environmental problems are related to each other, and different groups have differing amounts of influence. Does cooperation actually lead to a better environment?” says Örjan Bodin, lecturer at the Stockholm Resilience Centre who conducts interdisciplinary research on better ways to handle diverse environmental problems.

Food scraps. Okay, those aren’t the first words that come to mind when you think about the environment. But 22 percent of the municipal solid waste dropped into landfills or incincerators in the U.S. is, in fact, food that could be put to better use through composting and soil enrichment.
Moreover, food-scrap recycling programs, while still relatively uncommon, are having a growth moment in the U.S.; they’ve roughly doubled in size since 2010. Now, a national study by MIT researchers provides one of the first in-depth looks at the characteristics of places that have adopted food recycling, revealing several new facts in the process.

Researchers say their new knowledge on the inner workings of a bacterium has important implications for Australia’s billion dollar cheese industry.
University of Queensland School of Agriculture and Food Sciences researcher Associate Professor Mark Turner said a discovery by a UQ, Columbia University and University of Washington research group had explained the regulation of an enzyme in the bacterium Lactococcus, which is used as a starter culture in cheese production.

Originally a mineral, the perovskite used in today’s technology is quite different from the rock found in the Earth mantle. A “perovskite structure” uses a different combination of atoms but keep the general 3-dimensional structure originally observed in the mineral, which possesses superb optoelectronic properties such as strong light absorption and facilitated charge transport. These advantages qualify the perovskite structure as particularly suited for the design of electronic devices, from solar cells to lights.
The accelerating progress in perovskite technology over the past few years suggest new perovskite-based devices will soon outperform current technology in the energy sector. The Energy Materials and Surface Sciences Unit at OIST led by Prof. Yabing Qi is at the forefront of this development, with now two new scientific publications focusing on the improvement of perovskite solar cells and a cheaper and smarter way to produce emerging perovskite-based LED lights.

A research team from Predictive Science Inc. (PSI) used the Stampede2supercomputer at The University of Texas at Austin’s Texas Advanced Computing Center (TACC) to forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the U.S., tracing a 70-mile-wide band across 14 states.
Beyond their rarity, solar eclipses help astronomers better understand the sun’s structure, inner workings and the space weather it generates.
