Newly-developed nanovalves allow the flow of individual nanoparticles in liquids to be controlled in tiny channels. This is of interest for lab-on-a-chip applications such as in materials science and biomedicine.
In a study published in Nature, a UCLA-led team of researchers describe how the nanomachine recognizes and kills bacteria, and report that they have imaged it at atomic resolution. The scientists also engineered their own versions of the nanomachine, which enabled them to produce variations that behaved differently from the naturally occurring version.
Their efforts could eventually lead to the development of new types of antibiotics that are capable of homing in on specific species of microbes. Drugs tailored to kill only a certain species or strain of bacteria could offer numerous advantages over conventional antibiotics, including lowering the likelihood that bacteria will develop resistance. In addition, the tailored drugs could destroy harmful cells without wiping out beneficial bugs in the gut microbiome, and they could eventually offer the possibilities of being deployed to prevent bacterial infections, to kill pathogens in food and to engineer human microbiomes so that favorable bacteria thrive.

SANTA BARBARA, Calif., April 20, 2020 — Researchers at the University of California, Santa Barbara (UC Santa Barbara) are developing ultraviolet (UV) LEDs for decontaminating surfaces and potentially air and water that have come in contact with the SARS-CoV-2 virus.

Klotho has been called the “king of anti-aging proteins.” It is an important biomarker and promising gene therapy treatment for Chronic Kidney Disease. It is more strongly correlated with IQ than any single gene, making it a potential nootropic and intelligence enhancing gene therapy.

Nature spoke to the world’s major research funders to find out how they are adapting their funding policies in response to the pandemic.
As lockdowns force scientists worldwide to put their research on hold, funders are introducing measures to minimize stress.
Massachusetts Institute of Technology (MIT) researchers have developed a series of soluble, stabilized cytokine receptors that could feasibly be injected into COVID-19 patients to help reduce the effects of cytokine storm by binding to excess cytokines.

As many as 15,000 Russian troops trained for a parade with little, if any, social distancing. They are now headed into quarantine.
Two weeks ago, the world was stunned by drone photos and videos of mass burials of COVID-19 victims on an island that is part of the Bronx, in New York City. Last week, renowned photographer George Steinmetz set out to capture his own images, but police seized his drone. And now we have more details of how that went down. “These are humans, and they’re basically being treated like they’re toxic waste, like they’re radioactive,” Steinmetz told Gothamist about the people buried on Hart Island. The island has served as a potter’s field for New York’s unclaimed and anonymous dead since the 19th century.
The Department of Correction, which oversees Hart Island, would not provide an exact number of people buried on the island, but a spokesperson said it was as high as 47 people on a single day.
