Hot spot at Hawaii? Not so fast

Through analysis of volcanic tracks, Rice University geophysicists have concluded that hot spots like those that formed the Hawaiian Islands aren’t moving as fast as recently thought.

Hot spots are areas where magma pushes up from deep Earth to form volcanoes. New results from geophysicist Richard Gordon and his team confirm that groups of hot spots around the globe can be used to determine how fast tectonic plates move.

Gordon, lead author Chengzu Wang and co-author Tuo Zhang developed a method to analyze the relative motion of 56 hot spots grouped by tectonic plates. They concluded that the hot-spot groups move slowly enough to be used as a global reference frame for how plates move relative to the deep mantle. This confirmed the method is useful for viewing not only current plate motion but also plate motion in the geologic past.

Destruction of small wetlands directly linked to algal blooms in Great Lakes

Canada’s current wetland protection efforts have overlooked how the environment naturally protects fresh-water resources from agricultural fertilizer contaminants, researchers from the University of Waterloo have found.

In a recent study, researchers at Waterloo’s Faculty of Science and Faculty of Engineering found that small wetlands have a more significant role to play than larger ones in preventing excess nutrients like nitrogen and phosphorus from fertilizer from reaching waterbodies such as the Great Lakes.

Slippery liquid surfaces confuse mussels to stop them from sticking to underwater structures

Non-toxic, lubricant-infused coatings deter mussels and prevent their attachment by disrupting their mechanosensory and adhesive systems.

Genome analysis with near-complete privacy possible

It is now possible to scour complete human genomes for the presence of disease-associated genes without revealing any genetic information not directly associated with the inquiry, say Stanford University researchers.

This “genome cloaking” technique, devised by biologists, computer scientists and cryptographers at the university, ameliorates many concerns about genomic privacy and potential discrimination based on an individual’s genome sequence.

NASA Gets a Final Look at Hurricane Gert's Rainfall

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 Combine to Homogenize Nature

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.

Study Reveals Evolutionary History of Imperiled Salmon Stocks

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.

Right kind of collaboration is key to solving environmental problems

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.

Study: For food-waste recycling, policy is key

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.
