Modern prosthetic limbs help people with amputations walk naturally but don’t give full neural control. They use robotic sensors and pre-set algorithms to move. MIT researchers, with Brigham and Women’s Hospital, developed a new surgical method and neuroprosthetic interface. This allows a prosthetic leg to be controlled entirely by the nervous system. By reconnecting muscles

DNA is a much denser data storage medium than anything humans can design, but it is fragile. Scientists have now mimicked nature by creating artificial amber to protect DNA for long-term data storage.
A single gram of DNA can hold up to 215 petabytes (215 million GB) of data, making it possible to store the entire internet in a shoebox. Thus, scientists have been experimenting with writing, reading, and protecting data stored in DNA.

Total knee replacement surgery is a very common procedure where a damaged knee joint is replaced with an artificial one. In the U.S., about 790,000 of these surgeries happen each year, and this number is expected to go up because of aging populations, more obesity, and more young people needing knee replacements. The main reason

Researchers found that adopting a 5:2 intermittent fasting regimen – consuming normally for five days and abstaining from food for two – shielded against liver inflammation and did not lead to weight gain. They also pinpointed the proteins responsible for this protective effect.
A recent study discovered that even short bursts of anger triggered by memories can harm our blood vessels’ ability to relax. This finding has serious implications for understanding heart attack and stroke risks. Negative Emotions In the past, researchers observed a connection between negative emotions like anger and an increased risk of heart attacks. However,

Mark, who is 67 years old, found out he had ALS in 2020. Over time, he’s been losing his ability to do things like using his phone or feeding himself. But now, things are looking up. Last August, he got a special brain-computer interface called Synchron. ALS is a sickness where nerve cells break down,
Varda Space Industries, a company from California, did something amazing recently. They brought back samples of a medicine they made while in space. It wasn’t easy. The capsule carrying the samples had some problems and was stuck in space for a while. But finally, on February 21, it landed safely in the Utah desert. A
