With the advent of commercial spaceflight, an increasing number of people may be heading into space in the coming years. Some will even get a chance to fly to the moon or live on Mars.

One of the major health risks associated with spaceflight involves the immune system, which normally fights off viruses and cancer. It’s already established that spaceflight weakens immunity; current and past astronauts report clinical issues such as respiratory illnesses and skin rashes...

Researchers at the University of Massachusetts Amherst have shown that their nanoparticle-based vaccine can successfully prevent several aggressive cancers in mice, including melanoma, pancreatic cancer, and triple-negative breast cancer. Depending on the cancer type, up to 88% of vaccinated mice stayed tumor-free (depending on the cancer), and the vaccine also reduced — and in some cases completely prevented — the spread of cancer throughout the body.

“By engineering these nanoparticles to activate the immune system via multi-...

Engineered “stealth” immune cells from MIT and Harvard show promise for fast, safe, and powerful cancer treatment. Scientists have created a new and more advanced form of immune-based cancer therapy using engineered cells known as CAR-NK (natural killer) cells. Like CAR-T cells, these modified immune cells can be programmed to recognize and attack cancer, but they rely on a different type of immune cell that naturally targets abnormal or infected cells.

A team from MIT and Harvard Medical School has now developed a more effective way to engineer CAR-NK cells that dramatically reduces the chance of the body’s immune system rejecting them...

In a new study using AI and machine learning, EPFL researchers have found that it’s not only what we eat, but how consistently we eat it that plays a crucial role in gut health.

The gut microbiota is the community of microorganisms, including bacteria, viruses, fungi and other microbes, that lives in our digestive systems—some of these microbes are helpful and others can be harmful.

Many previous studies have shown that what we eat has an impact on our gut microbiota...
