Evidence of ancient lake sediments at the base of Mars’ Jezero Crater offer new hope for finding traces of life in samples collected by NASA’s Perseverance rover.

Perseverance touched down on Feb. 18, 2021 inside the Red Planet’s 28-mile-wide (45 kilometers) Jezero Crater, which is believed to have once hosted a large lake and river delta. The rover has been scouring the crater in search of signs of past life and collecting and caching dozens of samples along the way for a possible future return to Earth.

The space rock poses no threat to our planet, despite being on a path to zoom between Earth and the moon.

It crept up slowly, almost imperceptibly. A vague rawness at the back of my throat. A thrumming malaise. On Thanksgiving Day, it lunged.

For two weeks, I was in the grip of an unusually malevolent respiratory illness. But I was in good company: Nationwide, the percentage of health care visits for flulike symptoms ticked up above the baseline at the start of November and has remained elevated ever since, according to the Centers for Disease Control and Prevention.

“All the respiratory viruses are back in full force,” Anne Liu, MD, a Stanford Medicine immunologist and infectious disease specialist confirmed. The main reasons, she said, are fairly straightforward: Social distancing and masking are not popular choices in the wake of the pandemic.

Bioengineered bacteria sneak past solid tumor defenses to guide CAR T cells’ attacks.

A protein in the immune system can be manipulated to help overcome bowel cancer, according to new research from The Australian National University (ANU). The research is published in Science Advances.

Bowel cancer claims more than 100 lives in Australia each week, yet around 90% of cases can be successfully treated if detected early.

According to lead author Dr. Abhimanu Pandey, from ANU, the protein, known as Ku70, can be activated or “turned on” like a light switch by using a combination of new and existing drugs.

This microchip is the size of a grain of sand, and its job is to track data.

Inspired by nature, the latest microchip can dissolve and fly.

Study co-led by HMS scientist corrects gene mutation involved in inner ear function.

A test version of the company’s Zhuque-3 rocket soared about 1,150 feet (350 meters) high on Jan. 19.

This can free humans from taking on those tedious — and potentially dangerous — jobs, but it also means manufacturers need to build or buy a new robot every time they find a new task they want to automate.

General purpose robots — ones that can do many tasks — would be far more useful, but developing a bot with anywhere near the versatility of a human worker has thus far proven out of reach.
