A Northwestern University research team has developed a versatile composite fabric that can deactivate both biological threats, such as the novel coronavirus that causes COVID-19, and chemical threats, such as those used in chemical warfare. A material that is effective against both classes of threats is rare.

The material also is reusable. It can be restored to its original state after the fabric has been exposed to threats by a simple bleach treatment. The promising fabric could be used in and other protective clothing.

“Having a bifunctional material that has the ability to deactivate both and biological toxic agents is crucial since the complexity to integrate multiple materials to do the job is high,” said Northwestern’s Omar Farha, an expert in , or MOFs, which is the basis for the technology.

“The use of organophosphate esters in everything from TVs to car seats has proliferated under the false assumption that they’re safe,” said Heather Patisaul, lead author and neuroendocrinologist at North Carolina State University. “Unfortunately, these chemicals appear to be just as harmful as the chemicals they’re intended to replace but act by a different mechanism.”


Summary: Exposure to even low levels of common chemicals called organophosphate esters can harm IQ, memory, learning, and brain development overall in young children.

Chemicals increasingly used as flame retardants and plasticizers pose a larger risk to children’s brain development than previously thought, according to a commentary published today in Environmental Health Perspectives.

Acclaimed Harvard professor and entrepreneur Dr. David Sinclair believes that we will see human life expectancy increase to at least 100 years within this century. A world in which humans live significantly longer will have a major impact on economies, policies, healthcare, education, ethics, and more. Sinclair joined Bridgewater Portfolio Strategist Atul Lele to discuss the science and societal, political, systemic and ethical implications of humans living significantly longer lives.

What Increasing Life Expectancy Means for Individuals.

Back in June, the investor advocacy nonprofit As You Sow had filed a shareholder resolution with the Securities and Exchange Commission requesting that Microsoft examine the “environmental and social benefits of making its devices more easily repairable through measures such as the public provision of tools, parts, and repair instructions.” Prior to that resolution, Microsoft—like many tech companies—had essentially rigged the game so that its devices could only be fixed at authorized shops, effectively creating a monopoly on repairs that stifled consumer freedom and made everyone’s lives harder.

But on Thursday, Grist reported that Microsoft has now made a series of critical concessions as a result of that resolution, including a pledge to hire an independent consultant to study the ways increasing access to the parts and information could cut down on electronic waste and lessen damaging environmental impacts, and a commitment to acting on the findings of that study by the end of 2022.

“This is an encouraging step by Microsoft to respond to the upswell of federal and state activity in the right to repair movement,” Kelly McBee, waste program coordinator at As You Sow, said in a press release. “Excitingly, this agreement will begin to allow consumers to repair their Microsoft devices outside the limited network of authorized repair shops.”

Tokyo-based aircraft manufacturer Tetra Aviation revealed its first commercially available personal eVTOL (electric vertical take-off and landing) Mk-5 just a short while ago. It happened in July at this year’s AirVenture OSHKOSH event in Wisconsin, touted the world’s greatest aviation celebration. Now the company follows with a flight demonstration of the aircraft in California.

Vertical Aerospace has already collected somewhere in the region of 1,000 orders for their VA-X4 VTOL craft. This is a piloted electric, low emission eVTOL craft that can carry up to four passengers and a pilot. This air taxi is capable of flying at speeds of 200 mph (174 knots) and has a range of more than 100 miles (160 km).

Being all-electric, it is near-silent during flight, offers a low-carbon solution to flying, and has a relatively low cost per passenger mile.

Vertical Aerospace’s VA-X4 also makes use of the latest in advanced avionics — some of which are used to control the world’s only supersonic VTOL aircraft, the F-35 fighter. Such sophisticated control systems enable the eVTOL tax to fly with some high level of automation and reduced pilot workload.

Taiwan’s TSMC and Japan’s Sony Group Corp are considering jointly building a chip factory in Japan, with the government ready to pay for some of the investment of about 800 billion yen ($7.15 billion), the Nikkei reported on Friday, October 8 2021. (

WORLD’S LARGEST CHIPMAKER TO RAISE PRICES, THREATENING COSTLIER ELECTRONICS

Both Sony and TSMC declined to comment. But TSMC, the world’s largest contract chipmaker and major Apple Inc supplier had said in July that it was reviewing a plan to set up production in Japan.

Researchers in Japan have developed a vaccination strategy in mice that promotes the production of antibodies that can neutralize not only SARS-CoV-2 but a broad range of other coronaviruses as well. If successfully translated to humans, the approach, to be published October 8 in the Journal of Experimental Medicine, could lead to the development of a next-generation vaccine capable of preventing future coronavirus pandemics.

The SARS-CoV-2 virus responsible for COVID-19 enters human cells by using its to bind to a called ACE2. The receptor-binding domain of the spike protein consists of two parts: a “core” region that is very similar in all coronaviruses, and a more specialized “head” region that mediates binding to ACE2.

Antibodies that recognize the head region of the spike receptor-binding domain can block the entry of SARS-CoV-2 into cells but offer little protection against other coronaviruses, such as the SARS-CoV-1 virus responsible for the severe acute respiratory syndrome outbreak of 2002. Antibodies that recognize the core region of the spike receptor-binding domain, in contrast, can prevent the entry of various coronaviruses into . Unfortunately, however, individuals exposed to the viral spike protein tend to produce lots of against the head region but few, if any, antibodies that recognize the core region.
