Two missions will study the hellish planet to piece together its climate past, look for volcanoes, and see if it was ever habitable.

NASA Administrator and former astronaut Senator Bill Nelson announced today that the agency would be sending two missions to Venus. The two missions, called DAVINCI+ and VERITAS, will respectively study the planet’s atmosphere and geological history.

Scientists may have found a promising new treatment for Covid-19 after an experimental oral antiviral drug demonstrated the ability to prevent the coronavirus from replicating, the National Institutes of Health said Thursday, citing a new study.

The drug, called TEMPOL, can reduce Covid-19 infections by impairing an enzyme the virus needs to make copies of itself once it’s inside human cells, which could potentially limit the severity of the disease, researchers at the NIH said. The drug was tested in an experiment of cell cultures with live viruses.

“We urgently need additional effective, accessible treatments for COVID-19,” Dr. Diana W. Bianchi, director of the NIH’s National Institute of Child Health and Human Development, wrote in a statement. “An oral drug that prevents SARS-CoV-2 from replicating would be an important tool for reducing the severity of the disease.”

“We began this work last spring with the understanding that, like all viruses, mutations would occur in the SARS-CoV-2 virus, which causes COVID-19,” said senior study author Barton F. Haynes, M.D., director of the DHVI. “The mRNA vaccines were already under development, so we were looking for ways to sustain their efficacy once those variants appeared.

This approach not only provided protection against SARS-CoV-2, but the antibodies induced by the vaccine also neutralised variants of concern that originated in the United Kingdom, South Africa and Brazil. And the induced antibodies reacted with quite a large panel of coronaviruses.

Haynes’ team – whose work is published in Nature – built on earlier studies involving SARS, a respiratory illness caused by SARS-CoV-1. The original SARS virus emerged in November 2002, lasting until May 2004, with more than 8000 cases and 774 deaths, mostly in East Asia. The DHVI team found that a person infected with SARS developed antibodies capable of neutralising multiple coronaviruses, suggesting that a pan-coronavirus might be possible.

MIT researchers have developed the first fiber with digital capabilities that is able to capture, store, analyze and derive activity after it has been sewn into a shirt.

Yoel Fink, professor of materials science and electrical engineering, lead researcher at the Electronics Research Laboratory and lead author of the study, says digital fibers expand the possibilities for fabrics to uncover the context of hidden patterns in the human body that could be used for monitoring physical performance, medical conclusions and early disease detection are used.

The maximum lifespan for humans is between 120 and 150, according to a longitudinal analysis of blood markers, published in Nature.

In simple terms, comparing previous autonomy standards with that of Exyn is like the difference between self-navigating a single, defined road versus uncharted terrain in unknown and unmapped territory. Unlike a car, however, a drone must be able to manoeuvre within three dimensions and pack all its intelligence and sensors onto a fraction of the total body size with severe weight restrictions.

“People have been talking about Level 4 Autonomy in driverless cars for some time, but having that same degree of intelligence condensed onboard a self-sufficient UAV is an entirely different engineering challenge in and of itself,” said Jason Derenick, CTO at Exyn Technologies. “Achieving Level 5 is the holy grail of autonomous systems – this is when the drone can demonstrate 100% control in an unbounded environment, without any input from a human operator whatsoever. While I don’t believe we will witness this in my lifetime, I do believe we will push the limits of what’s possible with advanced Level 4. We are already working on attaining Level 4B autonomy with swarms, or collaborative multi-robot systems.”

“There’s things that we want to do to make it faster, make it higher resolution, make it more accurate,” said Elm, in an interview with Forbes. “But the other thing we were kind of contemplating is basically the ability to have multiple robots collaborate with each other so you can scale the problem – both in terms of scale and scope. So you can have multiple identical robots on a mission, so you can actually now cover a larger area, but also have specialised robots that might be different. So, heterogeneous swarms so they can actually now have specialised tasks and collaborate with each other on a mission.”

China has announced a milestone in the development of clean, sustainable energy by setting a new world record for the longest duration of temperatures needed for fusion to occur.

The Experimental Advanced Superconducting Tokamak (EAST) located in Hefei, Anhui Province, is the successor to HT-7, China’s first superconducting tokamak, which retired in 2013. The Hefei Institutes of Physical Science (HIPS) is conducting the experiment for the Chinese Academy of Sciences (CAS).

Professor Gong Xianzu, a researcher at the CAS Institute of Plasma Physics (IPP) who is leading the project, announced the breakthrough. The reactor achieved not one but two milestones. Firstly it reached a plasma temperature of 120 million degrees Celsius for 101 seconds. This is 20% hotter and five times longer than last year, when EAST managed 100 million degrees Celsius for 20 seconds. Secondly, it reached an even higher peak temperature of 160 million degrees Celsius, lasting for 20 seconds.

One of the spacecraft will probe the hellish planet’s clouds, which could potentially help settle the debate over whether they are habitable by floating microbes.

Culture drives human evolution more than genetics

I wonder about the thought that only humans do this, and perhaps that somehow culture is separate in some way from biological evolution enmeshed with the rest of the planet?
by University of Maine

Culture is an under-appreciated factor in human evolution, Waring says. Like genes, culture helps people adjust to their environment and meet the challenges of survival and reproduction. Culture, however, does so more effectively than genes because the transfer of knowledge is faster and more flexible than the inheritance of genes, according to Waring and Wood.
