Digital identity capabilities from Trust Stamp are now being integrated with Mastercard’s Wellness Pass solution, which it will launch in cooperation with Gavi in West Africa. Proving identity without revealing any information about it is the idea behind Trust Stamp’s zero knowledge approach to online identity verification, according to a profile by Mastercard.

Gareth Genner, Trust Stamp co-founder and CEO, explains in an interview how the company’s Evergreen Hash technology uses biometrics without taking on the risk of spoofing or a data breach that he says come with standard biometric implementations.

The Evergreen Hash is created from the customers face, palm or fingerprint biometrics, which the company uses to generate a “3D mask,” discarding raw data and adding encryption to associate the data with the user.

Please stop saying “There is no treatment for coronavirus”, coronavirus can be treated many ways. Anything can be treated many ways. When one says, “This can not be done”, one has already given up. When one says, “I can”, one at least makes an effort, and even failure is a lesson that leads to success. The WHO is already promoting the Moderna vaccine, yet it takes years to develop a vaccine properly. Any scientist will tell you it is faster to repurpose drugs than to develop a vaccine. Even in Kenya, they will not tell you how people are being treated, but already they are talking about the Moderna Vaccine.

Sometimes, old drugs find a new purpose. A widely available steroid called dexamethasone might hold the potential to save a lot of lives that otherwise would be lost to coronavirus. Preliminary results released from a randomized and controlled clinical trial involving more than 6,000 patients found that administering dexamethasone significantly reduced deaths among those with severe COVID-19 illnesses.

The study, which has not yet been published in a peer-reviewed journal, found that the drug reduced deaths by one-third among patients on mechanical ventilators, and by one-fifth among patients receiving other forms of supplemental oxygen. Although dexamethasone is a far cry from a coronavirus cure, it feels like the first good news to transpire since earlier this spring, when the antiviral drug remdesivir showed it could modestly improve survival among COVID-19 patients.

For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development. This work on one-cell embryos is set to shift our understanding of the mechanisms that underpin cellular behaviour in general, and may ultimately provide insights into what goes wrong in ageing and disease.

The research, led by Professor Tony Perry from the Department of Biology and Biochemistry at the University of Bath, involved injecting a silicon-based nanodevice together with sperm into the egg cell of a mouse. The result was a healthy, fertilised egg containing a tracking device.

The tiny devices are a little like spiders, complete with eight highly flexible ‘legs’. The legs measure the ‘pulling and pushing’ forces exerted in the cell interior to a very high level of precision, thereby revealing the cellular forces at play and showing how intracellular matter rearranged itself over time.

Want to learn how we age and whether we can slow or even reverse aging? David Sinclair, PhD, professor of genetics at Harvard Medical School, says in his book “Lifespan” that aging is a disease, and that disease is treatable. Tune in to Homeroom with Sal on Tuesday at noon PT to get your questions answered by a leading expert on aging and age-associated diseases.

A brilliant new light shines in Grenoble, France, where officials at the European Synchrotron Radiation Facility(ESRF) last week announced the reopening of their completely rebuilt x-ray source. The ring-shaped machine, 844 meters around, generates x-ray beams 100 times brighter than its predecessor and 10 trillion times brighter than medical x-rays. The intense radiation could open up new vistas in x-ray science, such as imaging whole organs in three dimensions while resolving individual cells.

Shining 100 times brighter than its predecessor, the new European Synchrotron Radiation Facility is the first of more than a dozen of its kind in the works.

(Reuters) — Nearly a third of more than 40 large companies seeking U.S. bankruptcy protection during the coronavirus pandemic awarded bonuses to executives within a month of filing their cases, according to a Reuters analysis of securities filings and court records.

Under a 2005 bankruptcy law, companies are banned, with few exceptions, from paying executives retention bonuses while in bankruptcy. But the firms seized on a loophole by granting payouts before filing.

Six of the 14 companies that approved bonuses within a month of their filings cited business challenges executives faced during the pandemic in justifying the compensation.

Do you agree with these predictions?

The first few months of 2020 have radically reshaped the way we work and how the world gets things done. While the wide use of robotaxis or self-driving freight trucks isn’t yet in place, the Covid-19 pandemic has hurried the introduction of artificial intelligence across all industries. Whether through outbreak tracing or contactless customer pay interactions, the impact has been immediate, but it also provides a window into what’s to come. The second annual Forbes’ AI 50, which highlights the most promising U.S.-based artificial intelligence companies, features a group of founders who are already pondering what their space will look like in the future, though all agree that Covid-19 has permanently accelerated or altered the spread of AI.

“We have seen two years of digital transformation in the course of the last two months,” Abnormal Security CEO Evan Reiser told Forbes in May. As more parts of a company are forced to move online, Reiser expects to see AI being put to use to help businesses analyze the newly available data or to increase efficiency.

With artificial intelligence becoming ubiquitous in our daily lives, DeepMap CEO James Wu believes people will abandon the common misconception that AI is a threat to humanity. “We will see a shift in public sentiment from ‘AI is dangerous’ to ‘AI makes the world safer,’” he says. “AI will become associated with safety while human contact will become associated with danger.”

Could be used for quasar propulsion: 3.

It seems the universe has an odd sense of humor. While a crown-encrusted virus has run roughshod over the world, another entirely different corona about 100 million light years from Earth has mysteriously disappeared.

For the first time, astronomers at MIT and elsewhere have watched as a supermassive black hole’s own corona, the ultrabright, billion-degree ring of high-energy particles that encircles a black hole’s event horizon, was abruptly destroyed.

The cause of this dramatic transformation is unclear, though the researchers guess that the source of the calamity may have been a star caught in the black hole’s gravitational pull. Like a pebble tossed into a gearbox, the star may have ricocheted through the black hole’s disk of swirling material, causing everything in the vicinity, including the corona’s high-energy particles, to suddenly plummet into the black hole.

🤔 The WHO Chief is urging African nations to take part in clinical trials for a vaccine, yet is sending a team to China 7 months after the fact, and after China destroyed samples. The same WHO also is complaining about countries handling of the outbreak.

The UN body announced that over 1.4 million infections of COVID-19 are accounted for by health care sector workers, at least 10% of all cases. EU leaders have met to discuss a recovery package. Follow DW for the latest.

The U.S. Navy welcomed a new amphibious assault ship into the fleet this week even as one of its sister ships lay burning. The ship, designed to deliver Marines by air into hostile territory, was commissioned in a low-key virtual ceremony to ensure social distancing. Tripoli will be based at San Diego Naval Base, California, where sister ship USS Bonhomme Richard is currently on fire.

The ship’s traditional commissioning ceremony, a public event that would have drawn thousands and originally set to take place at Pensacola, Florida, was canceled due to the ongoing COVID-19 pandemic. Instead the ship was commissioned by “administrative message” from the Navy to the fleet, while onboard the crew raised the commissioning flag to signify the event.
