Geologists identify deep-earth structures that may signal hidden metal lodes

If the world is to maintain a sustainable economy and fend off the worst effects of climate change, at least one industry will soon have to ramp up dramatically: the mining of metals needed to create a vast infrastructure for renewable power generation, storage, transmission and usage. The problem is, demand for such metals is likely to far outstrip currently both known deposits and the existing...

Mathematical noodling leads to new insights into an old fusion problem

A challenge to creating fusion energy on Earth is trapping the charged gas known as plasma that fuels fusion reactions within a strong magnetic field and keeping the plasma as hot and dense as possible for as long as possible. Now, scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have gained new insight into a common type of hiccup known as the...

Microscope allows gentle, continuous imaging of light-sensitive corals

Corals are "part animal, part plant, and part rock—and difficult to figure out, despite being studied for centuries," says Philippe Laissue of University of Essex, a Whitman Scientist at the Marine Biological Laboratory. Many corals are sensitive to bright light, so capturing their dynamics with traditional microscopes is a challenge.

SwRI's SLED-W algorithms detect crude oil on water

Southwest Research Institute has developed computer-based techniques to accurately detect crude oil on water using inexpensive thermal and visible cameras. This machine learning-based solution can detect and monitor oil leaks before they become major threats to lakes, rivers and coastal areas.

New winter squash decline research paves the way for understanding the disease

Winter squash is an important crop grown in the Willamette Valley, and the most important processing cultivar, Golden Delicious, has been grown in Oregon since the 1970s. Over the last two decades, however, growers have noticed yield declines throughout the valley. Agriculture specialists have identified an association between yield decline and disease symptoms such as stunting, vascular...

How a protein's small change leads to big trouble for cells

In molecular biology, chaperones are a class of proteins that help regulate how other proteins fold. Folding is an important step in the manufacturing process for proteins. When they don't fold the way they're supposed to, it can lead to the development of diseases such as cancer.

Scientists investigate epigenetic impact across whole genome

All life depends on a genome, which acts as an instruction manual for building all the products essential for development and survival. But knowing which of these individual instructions—or genes—need to be read, and when, is key for a properly functioning organism: so how does life get this right?

Terrawatch: unearthing snow's 'Fukushima layer'

Chinese glaciologists have found the freeze-thaw process has concentrated discharge from the disasterThe Fukushima nuclear accident has added a distinctive signature to snow and ice across the northern hemisphere, new research published in Environmental Research Letters shows. Triggered by the Tōhoku earthquake and tsunami off the coast of Japan on 11 March 2011, the disaster resulted in a...

Microscope allows gentle, continuous imaging of light-sensitive corals

Many corals are sensitive to bright light, so capturing their dynamics with traditional microscopes is a challenge. To work around their photosensitivity, researchers developed a custom light-sheet microscope (the L-SPI) that allows gentle, non-invasive observation of corals and their polyps in detail over eight continuous hours, at high resolution.

Going lean: How vendor consolidation creates big gains

The second quarter of 2020 launched many digital transformation projects that didn’t necessarily happen at the behest of chief innovation officers, but because of the wrecking ball of disruption known as covid-19. Even if companies did succeed at rapidly orienting operations and services to digital, the transformation journey is far from over—and that means procurement and vendor management...

Chemist adds details of 'cold collisions of hot molecules' to theories of molecular interactions

When two cars collide at an intersection -- from opposite directions -- the impact is much different than when two cars -- traveling in the same direction -- 'bump' into each other. In the laboratory, similar types of collisions can be made to occur between molecules to study chemistry at very low temperatures, or 'cold collisions.' A team of scientists has developed a new experimental approach to...
