There are many processes and proteins that help the body fight a flu infection. One of them is known as IFITM3. Researchers have now shown that this protein can help prevent viruses from mutating after they have infected a new host. But some people are deficient in IFITM3, which can raise their risk of a severe flu infection. That deficiency is not unusual in some groups. For example, around twenty percent of Chinese people and four percent of people with European ancestry carry variants in IFITM3 that can interfere with the protein’s expression. This study has shown that these genetic variants can allow flu viruses to establish infections even when the virus is present at very low levels that would not usually cause infection. The findings have been reported in Nature Communications.

Sometimes there are slightly different versions, or sequences of genes. There are several versions of the apolipoprotein E (APOE) gene, for example. One of them, called APOE4, has been linked to a much higher risk of developing Alzheimer’s disease, and carriers often have worse forms of the disease compared to carriers of other forms like APOE3. There are immune cells in the brain called microglia that help protect the brain from damage and harm. But when APOE4 is expressed, microglia seem to start to cause inflammation, and misfolded proteins to form in the brain, which can lead to serious problems. The findings have been reported in Cell Stem Cell.

When it comes to artificial intelligence (AI), opinions run the gamut. Some see AI as a miraculous tool that could revolutionize every aspect of our lives, while others fear it as a force that could upend society and replace human ingenuity. Among these diverse perspectives lies a growing fascination with the cognitive abilities of AI: Can machines truly “understand” us? Recent research suggests that advanced language models like ChatGPT-4 may be more socially perceptive than we imagined.

A team of researchers is growing wood fibers from cells, which could reduce tree felling.

Which of the nearly 6,000 known exoplanets have atmospheres? With help from JWST, astronomers are inching closer to an answer, and new observations of a super-Earth planet around a low-mass star help to define the dividing line between planets with atmospheres and planets without.

Numbers tell a story. From your credit score to your age, metrics predict a variety of outcomes, whether it’s your likelihood to get a loan or your risk for heart disease. Now, Stanford Medicine researchers have described another telling metric — one that can predict mortality. It’s called sleep age.

For my presentation at the 7th Eurosymposium on Healthy Aging in Brussels tomorrow, I’ve significantly updated my slides “Solving Aging: Is AI all we need?” — It’s still possible to register and attend remotely today and/or tomorrow.

Returning to those Red Monsters, the new JWST data showed that these galaxies produce stars at about two to three times more efficiently than galaxies in the later universe.
