A new study by University of Alberta scientists shows that banded iron formations originated from oxidized iron, confirming the relevance and accuracy of existing models--a finding of great importance to the geological community.
WASHINGTON, D.C., JUNE 6 -- Sustainability-driven new research could one day help tuna fisheries cast their nets more selectively, mitigating unintentional "bycatch" of undersized fish and off-limits species.
The key development is an innovative application of electronic fish-finders like those commonly used by commercial tuna fleets. A multinational research team conducted the investigation under the sponsorship of the International Seafood Sustainability Foundation (ISSF).
'Families might be putting their own issues on the back burner while their kid gets help'
Very little research has examined the effect of treating teens, with medication or psychotherapy, on family relationships
CHICAGO - Parents often seek mental health treatment for a child struggling with depression, but the treatment shouldn't stop with the depressed teen, suggests a new Northwestern Medicine study.
Irvine, Calif., June 6, 2019 - In a paper published this week in Nature, materials science researchers at the University of California, Irvine and other institutions unveil a new process for producing oxide perovskite crystals in exquisitely flexible, free-standing layers.
ANU and Uni of Melbourne Archaeologists have discovered 15 new sites in Laos containing more than one hundred 1000-year-old massive stone jars possibly used for the dead.
The jars of Laos are one of archaeology's enduring mysteries. Experts believe they were related to disposal of the dead, but nothing is known about the jars' original purpose and the people who brought them there.
The new finds show the distribution of the jars was more widespread than previously thought and could unlock the secrets surrounding their origin.
Tohoku University researchers have developed a technique using a hollow
sphere to measure the electronic and optical properties of large semiconducting crystals. The approach, published in the journal Applied Physics Express, improves on current photoluminescence spectroscopy techniques and could lead to energy savings for mass producers, and thus consumers, of power devices.
In spintronics, the use of organic materials as a "spin transport material" has recently garnered significant attention as they exhibit long spin-relaxation times and long spin-diffusion lengths owing to the weak spin-orbit interaction (SOI) of light elements. Meanwhile, the weak SOI of organic materials become a drawback when they are used as a "spin filter". A spin-polarized current is, therefore, typically generated by inorganic materials with ferromagnetism or strong SOIs.
PITTSBURGH, June 7, 2019 - The faster fluid is removed using continuous dialysis from patients with failing kidneys, the higher the likelihood they will die in the next several months, according to a study published today in JAMA Network Open by University of Pittsburgh School of Medicine researchers.
Coral reef experts from around the world are calling for an urgent re-evaluation of our climate goals in the light of increasing evidence of unprecedented speed of change to these fragile ecosystems.
Coral reefs, which have functioned relatively unchanged for some 24 million years, are now going through profound changes in their make-up.
Extreme erosion of Arctic coastlines in a changing climate - up to a metre a day - has been revealed with drone surveys.
Storms in the Canadian Arctic are washing away increasing amounts of coastal permafrost - frozen ground - which is exposed when sea ice melts during the summer.
The results highlight the ongoing change in the region, as a warming climate leads to longer summer seasons. Sea ice melts earlier and reforms later in the year than before, exposing the coastline and presenting more opportunities for storms to cause damage.
As sessile organisms, plants rely on their ability to adapt the development and growth of their roots in response to changing nutrient conditions. One such response, known to be displayed by plants grown in low nitrogen conditions, is the elongation of primary and lateral roots to explore the surrounding soil. This adaption to the lack of the essential element nitrogen is of particular interest, as it reflects a "foraging strategy", by which the root system can exploit nutrients from a larger soil volume. Until recently, this was the least understood nitrogen-dependent root response.
Large parts of Asian Russia could become habitable by the late 21st century due to climate change, new research has found.
A study team from the Krasnoyarsk Federal Research Center, Russia, and the National Institute of Aerospace, USA, used current and predicted climate scenarios to examine the climate comfort of Asian Russia and work out the potential for human settlement throughout the 21st century.
They published their results today in Environmental Research Letters.
Something as simple as chatting with your neighbours about their new energy-efficient home renovations can affect wider climate change predictions, a new University of Guelph study reveals.
Using a new model that couples human behaviour to climate systems, Canadian researchers including a U of G ecologist have discovered that including social processes can alter climate change predictions, a finding that may hold a way to stem or even reduce global warming.
Elasmobranches - sharks, rays, and skates - are at an elevated risk of extinction due to overfishing, and Indonesia is a global hub for commercial fishing for these slow-growing, cartilaginous fishes.
Researchers analyzed four years of catch data from Tanjung Luar - a fishing village specifically targeting sharks - to identify catch abundance and seasonality of vulnerable or endangered species, and found that catch per unit effort (CPUE) of sharks and rays from 2014 to 2017 fluctuated but was not significantly different.
An international team of researchers recently synthesized polyarylether-based covalent organic frameworks, the most stable crystalline porous material on record. The team, which includes the University of Delaware's Yushan Yan and Jilin University's Qianrong (Frank) Fang, a former postdoctoral researcher with Yan at UD, described their results in the international scientific journal Nature Chemistry.
