Scientists identify three causes of Earth's spin axis drift
Wed, 19 Sep 2018 19:59:06 EDT
Using observational and model-based data spanning the entire 20th century, scientists have for the first time have identified three broadly-categorized processes responsible for Earth's spin axis drift -- contemporary mass loss primarily in Greenland, glacial rebound, and mantle convection.
Super cheap earth element to advance new battery tech to the industry
Wed, 19 Sep 2018 15:41:46 EDT
Worldwide efforts to make sodium-ion batteries just as functional as lithium-ion batteries have long since controlled sodium's tendency to explode, but not yet resolved how to prevent sodium-ions from 'getting lost' during the first few times a battery charges and discharges. Now, researchers made a sodium powder version that fixes this problem and holds a charge properly.
Flu season forecasts could be more accurate with access to health care companies' data
Wed, 19 Sep 2018 15:41:43 EDT
New research shows that data routinely collected by health care companies -- if made available to researchers and public health agencies -- could enable more accurate forecasts of when the next flu season will peak, how long it will last and how many people will get sick.
Outside competition breeds more trust among coworkers
Wed, 19 Sep 2018 14:49:23 EDT
Working in a competitive industry fosters a greater level of trust amongst workers, finds a new study.
From crystals to climate: 'Gold standard' timeline links flood basalts to climate change
Wed, 19 Sep 2018 14:49:20 EDT
Princeton geologists used tiny zircon crystals found in volcanic ash to rewrite the timeline for the eruptions of the Columbia River flood basalts, a series of massive lava flows that coincided with an ancient global warming period 16 million years ago.
'Robotic Skins' turn everyday objects into robots
Wed, 19 Sep 2018 14:49:18 EDT
When you think of robotics, you likely think of something rigid, heavy, and built for a specific purpose. New 'Robotic Skins' technology flips that notion on its head, allowing users to animate the inanimate and turn everyday objects into robots.
DNA tests of illegal ivory link multiple ivory shipments to same dealers
Wed, 19 Sep 2018 14:49:13 EDT
Scientists report that DNA test results of large ivory seizures made by law enforcement have linked multiple ivory shipments over the three-year period, when this trafficking reached its peak, to the same network of dealers operating out of a handful of African ports.
Unprecedented ice loss in Russian ice cap
Wed, 19 Sep 2018 14:49:10 EDT
In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study. That dwarfs the ice's previous average speed of about 2 inches per day and has challenged scientists' assumptions about the stability of the cold ice caps dotting Earth's high latitudes.
Quantum anomaly: Breaking a classical symmetry with ultracold atoms
Wed, 19 Sep 2018 13:39:15 EDT
A new study of ultracold atomic gases finds a quantum anomaly: strongly interacting particles breaking classical symmetry in a 2-D Fermi gas.
Improving 'silvopastures' for bird conservation
Wed, 19 Sep 2018 13:39:10 EDT
The adoption of 'silvopastures' -- incorporating trees into pastureland -- can provide habitat for forest bird species and improve connectivity in landscapes fragmented by agriculture. But how do silvopastures measure up to natural forest habitat? New research shows that birds in silvopasture forage less efficiently than those in forest fragments but offers suggestions for how silvopasture habitat could be improved.
Newly identified African bird species already in trouble
Wed, 19 Sep 2018 13:39:07 EDT
Central Africa's Albertine Rift region is a biodiversity hotspot consisting of a system of highlands that spans six countries. Recent studies have shown that the population of sooty bush-shrikes occupying the region's mid-elevation forests is a distinct species, and new research reveals that this newly discovered species may already be endangered due to pressure from agricultural development.
Commercially relevant bismuth-based thin film processing
Wed, 19 Sep 2018 13:36:23 EDT
Researchers prepared 2D layered, visible-light-absorbing bismuth sulfide semiconductors using a two-step process. The resulting film exhibited morphology that supported excellent semiconductor performance. The simplicity and versatility of the processing method, which uses non-toxic, abundant materials, makes bismuth sulfide a viable alternative to commercially available photoresponsive devices.
Anti-inflammatory protein promotes healthy gut bacteria to curb obesity
Wed, 19 Sep 2018 13:36:16 EDT
Scientists have discovered that the anti-inflammatory protein NLRP12 normally helps protect mice against obesity and insulin resistance when they are fed a high-fat diet. The researchers also reported that the NLRP12 gene is underactive in people who are obese, making it a potential therapeutic target for treating obesity and diabetes, both of which are risk factors for cardiovascular disease and other serious conditions.
More doctor visits lead to fewer suicide attempts for fibromyalgia patients
Wed, 19 Sep 2018 13:36:12 EDT
Fibromyalgia patients who regularly visit their physicians are much less likely to attempt suicide than those who do not, according to a new study.
Lighting it up: A new non-toxic, cheap, and stable blue photoluminescent material
Wed, 19 Sep 2018 13:33:17 EDT
Scientists have designed a novel photoluminescent material that is cheap to fabricate, does not use toxic starting materials, and is very stable, enhancing our understanding of the quantic nature of photoluminescence.
