Scientists from the Technion-Israel Institute of Technology say they have found a way to rejuvenate the aging process of the body’s immune system.
Prof. Doron Melamed and doctoral student Reem Dowery sought to understand why the elderly population is more susceptible to severe cases of COVID-19 and why the vaccines seem to be less effective and wane faster among this population.
The results of their work were published this month in the peer-reviewed, online medical journal Blood.

As work in real and model embryos movesforward, scientists are keen to know how similar the two really are. Finding out how models differ in their molecular details, and how their cells behave, is the main reason researchers wish to push beyond 14 days in real embryos. “We can learn a lot from a model,” says Jesse Veenvliet, a developmental biologist at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany. “But it’s important to know where it goes wrong.”
Researchers are now permitted to grow human embryos in the lab for longer than 14 days. Here’s what they could learn.
Russian start-up NTechLab has released FindFace Multi, a detection technology that uses an advanced algorithm to recognize not only faces, but also bodies of people and cars. This is an update to the company’s flagship product and is able to support numerous video streams and facial database entries.
Body recognition allows FindFace Multi users to count and search people moving through an environment as well as identifying individuals and tracking movements. The algorithm also takes into account markers such as height, color of clothes and accessories.
The vehicle recognition function determines the body type, color, manufacturer, and model of a car, as well as searching by license plate. Even if license plates, or parts of the vehicle are not visible or obscured, the system can still identify a car.
As the use of facial recognition technology (FRT) continues to expand, Congress, academics, and advocacy organizations have all highlighted the importance of developing a comprehensive understanding of how it is used by federal agencies.
The Government Accountability Office (GAO) has surveyed 24 federal agencies about their use of FRT. The performance audit ran from April2020through August 2021. 16 of the 24 agencies reported using it for digital access or cybersecurity, such as allowing employees to unlock agency smartphones with it, six agencies reported using it to generate leads in criminal investigations, five reported using FRT for physical security, such as controlling access to a building or facility, and 10 agencies said they planned to expand its use through fiscal year 2023.
In addition, both the Department of Homeland Security (DHS) and the Department of State reported using FRT to identify or verify travelers within or seeking admission to the United States, identifying or verifying the identity of non-U.S. citizens already in the United States, and to research agency information about non-U.S. citizens seeking admission to the United States. For example, DHS’s U.S. Customs and Border Protection used its Traveler Verification Service at ports of entry to assist with verifying travelers’ identities. The Traveler Verification Service uses FRT to compare a photo taken of the traveler at a port of entry with existing photos in DHS holdings, which include photographs from U.S. passports, U.S. visas, and other travel documents, as well as photographs from previous DHS encounters.
Tardigrades are undoubtedly weird. Dehydrate them into glass, then fire them out of a gun, and once you rehydrate them you can still have a living creature. Their outsides aren’t the only thing that’s tough either, with scientists finding last year that they also have special DNA armor proteins.
But if we take a step back from their immense capacity for being beaten up, there are many other mysterious things about them. For starters, how do these tiny creatures walk?
After all, they’re one of the only animals with soft little bodies like this that can walk, plus they’re one of the smallest animals with legs that we know of.
After all, Jupiter doesn’t have a solid core.
These planets are mostly made of gas, but a spaceship would have a rough time trying to get through a giant planet like Jupiter or Saturn.
The most powerful way to combat anxiety is to consistently work on building your resilience and mental strength. “Along the way, you’ll learn to appreciate or even welcome certain kinds of mistakes for all the new information they bring you,” says neuroscientist Wendi Suzuki.
The voices on Amazon’s Alexa, Google Assistant and others still lack the rhythms and intonation that make speech human. NVIDIA has unveiled new tools that can capture those natural speech qualities.
