FAU team of researchers succeed for the first time in accelerating electrons using a nano device.

Microscopes boosted beyond limits.

It’s been a month since a Maryland man became the second person to receive a transplanted heart from a pig — and hospital video released Friday shows he’s working hard to recover.

Lawrence Faucette was dying from heart failure and ineligible for a traditional heart transplant when doctors at the University of Maryland School of Medicine offered the highly experimental surgery.

In the first glimpse of Faucette provided since the Sept. 20 transplant, hospital video shows physical therapist Chris Wells urging him to push through a pedaling exercise to regain his strength.

Researchers have developed a potentially revolutionary superlens technique that once seemed impossible to see things four times smaller than even the most modern microscopes have seen before. Known as the ‘diffraction limit’ because the diffraction of light waves at the tiniest levels has prevented microscopes from seeing things smaller than those waves, this barrier once seemed unbreakable.

Many have tried to peer below this optical barrier using a technique that researchers in the field term ‘superlensing, including making customized lenses out of novel materials. But all have gathered too much light. Now, a team of physicists from the University of Sydney says they have discovered a viable path that peeks beyond the diffraction limit by a factor of four times, allowing researchers to see things smaller than ever seen before. And the way they did, it is like nothing anyone else has tried.

Breaking the Diffraction Limit by ‘Superlensing’ without a Superlens.

Unfortunately, these precise cell arrangements are also why artificial muscles are difficult to recreate in the lab. Despite being soft, squishy, and easily damaged, our muscles can perform incredible feats—adapt to heavy loads, sense the outside world, and rebuild after injury. A main reason for these superpowers is alignment—that is, how muscle cells orient to form stretchy fibers.

Now, a new study suggests that the solution to growing better lab-grown muscles may be magnets. Led by Dr. Ritu Raman at the Massachusetts Institute of Technology (MIT), scientists developed a magnetic hydrogel “sandwich” that controls muscle cell orientation in a lab dish. By changing the position of the magnets, the muscle cells aligned into fibers that contracted in synchrony as if they were inside a body.

The whole endeavor sounds rather Frankenstein. But lab-grown tissues could one day be grafted into people with heavily damaged muscles—either from inherited diseases or traumatic injuries—and restore their ability to navigate the world freely. Synthetic muscles could also coat robots, providing them with human-like senses, flexible motor control, and the ability to heal after inevitable scratches and scrapes.

Scientists at Kyushu University report that turning brain immune cells into neurons restores brain function after stroke-like injury in mice. Their findings suggest that replenishing neurons from immune cells could be a potential avenue for treating stroke in humans.

The findings are published in PNAS in an article titled, “Direct neuronal conversion of microglia/macrophages reinstates neurological function after stroke.”

“Although generating new neurons in the ischemic injured brain would be an ideal approach to replenish the lost neurons for repairing the damage, the adult mammalian brain retains only limited neurogenic capability,” wrote the scientists. “Here, we show that direct conversion of microglia/macrophages into neurons in the brain has great potential as a therapeutic strategy for ischemic brain injury.”

The company has also introduced a new robotic system called Sequoia to assist employees in fulfilling consumer requests, which is applied to one of its fulfillment centers in Houston, Texas.

Tesla has shared a video of a hands-free drive demonstration of its Full Self-Driving suite in Austin. The FSD suite is not available to customers in a hands-free nature, but Tesla disabled the requirement for a new video it shared on X, formerly known as Twitter.

Tesla shared the video to demonstrate the capabilities of Software Version 11.4.7, which is the current version of the FSD Beta program.

The automaker describes in the Tweet in put up how the Full Self-Driving suite improves through data-driven techniques that refine the capabilities through analysis of other drivers’ behavior and normal navigation habits.
