We screened a carefully designed chemical library to find F508del-CFTR correctors. The initial active compound resulting
Declines in commercial landings and increases in fishing fleet power have raised concerns over the continued provisioning of nutritional and economic services by tropical wild fisheries. Yet, because tropical fisheries are often data-poor, mechanisms that might buffer fishers to declines are not understood. This data scarcity undermines fisheries management, making tropical fishing livelihoods pa
New work shows how using next-generation DNA sequencing on ancient packrat middens — nests made out of plant material, fragments of insects, bones, fecal matter, and urine — could provide ecological snapshots of Earth's past. The study may pave the way for scientists to better understand how plant communities — and possibly animals, bacteria, and fungi as well — will respond to human-caused cl
When you were a kid you probably figured that in the future, the whole world would be powered by solar panels . After all, sunlight is free, and converting it into electricity doesn't pollute the atmosphere. Solar panels kind of seem like a no brainer. Unfortunately, as you have probably noticed, it's now 2020 and we're not living in a futuristic solar panel utopia yet. But we are getting closer
Studying the fossilized traces of diseases in dinosaurs can help researchers better understand how these maladies have changed over time. (Wikimedia Commons/) For February, we're focusing on the body parts that shape us, oxygenate us, and power us as we take long walks on the beach. Bony bonafide bones. These skeletal building blocks inspire curiosity and spark fear in different folks—we hope our
A new study documented the earliest known interbreeding event between ancient human populations — a group known as the 'super-archaics' in Eurasia interbred with a Neanderthal-Denisovan ancestor about 700,000 years ago. The event was between two populations more distantly related than any other recorded. The authors proposed a revised timeline for human migration out of Africa and into Eurasia. T
The retrosplenial cortex is reciprocally connected with multiple structures implicated in spatial cognition, and damage to the region itself produces numerous spatial impairments. Here, we sought to characterize spatial correlates of neurons within the region during free exploration in two-dimensional environments. We report that a large percentage of retrosplenial cortex neurons have spatial rec

Nature Communications, Published online: 21 February 2020; doi:10.1038/s41467-020-14753-8 Material interfaces are highly crucial to improve device performances. Here, the authors report interfacial reconstruction at the Au {001} substrate surface and the top MoS2 and WS2 monolayers due to the formation of a metastable interfacial Au4S4 phase. The reconstructed interface results in a p-type Schott

Walking is one of our most natural, daily actions. Now, a new study led by a Tohoku University researcher suggests that walkers use step synchronization as a form of non-verbal social communication. The results lend credence to the effects of psychological traits on movement interaction between humans.
Enough water will come from the ground as a byproduct of oil production from unconventional reservoirs during the coming decades to theoretically counter the need to use fresh water for hydraulic fracturing operations in many of the nation's large oil-producing areas. While other industries might want to recycle some of that water for their own needs, water quality issues and the potential costs i
I'm thinking 10 years from now. What are the challenges and privileges this country would face if it followed the millennial ideal of perfect world? submitted by /u/155matt [link] [comments]
Researchers from the MPSD and the Lawrence Berkeley National Laboratory (LBNL) in the United States have discovered a significant new fundamental kind of quantum electronic oscillation, or plasmon, in atomically thin materials. Their work has now been published in Nature Communications. It has potential implications for novel imaging techniques and photochemical reactions at the nanoscale.
Carbon nanotubes have gotten a lot of hype for being hundreds of times stronger than steel and better at conducting electricity than copper. The potential applications are pretty much limitless, so what's holding them up? submitted by /u/kernals12 [link] [comments]
Nature, Published online: 21 February 2020; doi:10.1038/d41586-020-00381-1 It's important not to take reviewers' comments personally, even if you feel they have misunderstood the science, Adam Levy discovers.
Hunting scene dated to 40,000 years ago 'crumbling before our eyes', say scientists The oldest known figurative paintings in the world, located near a cement mine in Indonesia, are under threat from industry, scientists have warned. In December, cave paintings depicting a hunting scene in the Indonesian island of Sulawesi were dated to at least 40,000 years ago . Continue reading…
A star of about eight percent the Sun's mass has been caught emitting an enormous 'super flare' of X-rays—a dramatic high-energy eruption that poses a fundamental problem for astronomers, who did not think it possible on stars that small.
