A vicious cycle of oxygen loss threatens water quality in lakes, new Virginia Tech study says
Peer-Reviewed Publication
Scientists have recently confirmed that the world’s lakes are rapidly losing oxygen. With a seven-year, whole-ecosystem study, a team of freshwater scientists at Virginia Tech has been one of the first to take the next step in asking: What does it mean for water quality that oxygen is declining globally?
Researchers at the Francis Crick Institute have developed an imaging technique to capture information about the structure and function of brain tissue at subcellular level – a few billionth of a metre, while also capturing information about the surrounding environment. The unique approach detailed in Nature Communications today (25 May), overcomes the challenges of imaging tissues at different scales, allowing scientists to see the surrounding cells and how they function, so they can build a complete picture of neural networks in the brain.
Scientists and other experts are calling on governments to start including animal welfare in sustainable development governance now in order to work towards a healthier, more resilient, and more sustainable world for all.
Around the world, hundreds of millions of acres of land are being abandoned. Land regeneration could restore habitats and sequester carbon, but this is unlikely to happen without policy interventions, according to a new study in Science Advances, which shows that much of the land is eventually recultivated.
Unique MoS2-SnS2 heterogeneous nanoplates have in-situ grown on poly(zwitterionic liquids) functionalized polypyrrole/graphene oxide by the interfacial induced effect, which act as electrocatalysts and exhibit good NRR performance by the synergistic effect.
An alliance of research teams, led by Dr. Tae-Young Yoon in Seoul National University – the first in the world to observe the folding process of a glucose transporter protein in vitro – has found a common evolutionary principle among metazoan membrane proteins. Throughout their evolutionary history, the membrane proteins had to strike a balance between their ability to fold into structures and their capability to transport sugars across cell barriers.
As Australia continues to mop up after one of the wettest years on record, councils might want to consider a new flood mitigation strategy proposed by UniSA engineers - permeable pavements to suit specific soil and rainfall conditions.
Engineers at RMIT University in Australia have discovered a bitumen blend that is both UV-resistant and withstands traffic loads, with the potential to save governments millions on road maintenance annually.
Data from a new USC study shows a significant increase in the risk of severe outcomes for COVID-19 patients exposed to fine particles (PM2.5) and nitrogen dioxide (NO2), two common (and correlated) components of ambient air pollution in Southern California. Produced by ground and air traffic, industrial burning and other sources, these air pollutants can exacerbate the effects of the SARS-CoV-2 virus over both the short and long term. Researchers collaborated with Kaiser Permanente Southern California to examine a cohort of more than 74,000 COVID-19 patients diagnosed from March to August 2020. With detailed residential address history linked to Kaiser Permanente members’ electronic medical records, investigators were able to accurately predict exposure history for specific pollutants.
The world’s only nocturnal hawk – Australia’s Letter-winged kite - may not be any better at seeing in the dark than its closest, day-hunting relatives. An international study, led by Flinders University’s Weisbecker Lab, has revealed that the rarely observed kite’s visual system is no different to that of its close relatives that are active during the day, challenging many decades of speculation that the Letter-winged Kite might be becoming more like an owl than a hawk.
A new retrospective study of seven patients diagnosed with monkeypox in the UK between 2018 and 2021, suggests that some antiviral medications might have the potential to shorten symptoms and reduce the amount of time a patient is contagious. The cases analysed in the study, published in The Lancet Infectious Diseases journal, represent the first instances of in-hospital transmission and household transmission outside of Africa, as well as reporting the patient response to the first off-label use of two different antiviral medications – brincidofovir and tecovirimat – to treat the disease.
A grim prediction made half a decade ago by University of Pittsburgh School of Public Health epidemiologists and modelers has come true: More than 100,000 people are now dying from drug overdoses annually in the U.S. The milestone comes as the International Journal of Drug Policy publishes a special section of the June issue reflecting on the exponential growth in drug-related deaths the Pitt team uncovered in 2017.
