Summary: Aging disrupts memory by increasing levels of the protein FTL1 in the hippocampus, new research shows. In mice, excess FTL1 caused neurons to grow abnormally and led to memory decline, while reducing FTL1 reversed these impairments. Old mice with suppressed FTL1 regained youthful neural connections and performed better on memory tasks. The findings suggest that blocking FTL1 may open …

Protein is having its moment: From grocery store shelves to Instagram feeds, high-protein foods are everywhere. Food labels shout their protein content in bold, oversized fonts, while social media overflows with recipes promising to pack more protein into your favourite dishes. And according to the International Food Information Council’s Food and Health Survey, “high protein” topped the list of popular …

Aging is particularly harsh on the hippocampus — the brain region responsible for learning and memory. Now, researchers at UC San Francisco have identified a protein that’s at the center of this decline. They looked at how the genes and proteins in the hippocampus changed over time in mice and found just one that differed between old and young animals. …

Animal models The following mouse lines were used: C57BL/6J mice (The Jackson Laboratory, line 000664), C57BL/6 aged mice (National Institutes of Aging) and B6;129-Gt(ROSA)26Sortm1(CAG-cas9*,-EGFP)Fezh/J (The Jackson Laboratory, line 024857). All studies were done in young (2–3 months) or aged (18–22 months) male mice that were not involved in any previous procedures. The numbers of mice used to result in statistically significant differences …

A few weeks ago, Explain It to Me — Vox’s weekly call-in podcast — went on a field trip to our local Whole Foods supplement aisle, where there were powders and pills and tinctures galore. These supplements promised to do everything from reducing wrinkles, to maintaining focus, to keeping your gut biome intact. But how much of that is true? …

“This photograph shows me checking microalgae at the TUMCREATE research campus in Singapore. It’s affiliated with several Singaporean organizations, as well as with the Technical University of Munich, Germany. The microalgae will ultimately make it into the meat alternative that my team and I are developing. We work with microalgae along with soy beans, because they’re both raw materials with …

Most of us eat enough protein. But there are exceptions, like illness or intense exercise. When your body doesn’t get the protein it needs, it sends you subtle hints.  These include bad mood, frequent illness or trouble bouncing back from exercise. Sometimes, getting the nutrients you need can feel like trying to balance a seesaw. Just when one side is …

Protein supplements may help increase time to exhaustion during endurance workouts. No major changes in body fat, body weight or VO2max were found from protein use. The benefits of protein may vary by training level, supplement type and dietary intake. Protein supplements are a popular choice to help meet protein needs, especially when it’s challenging to get enough in your …

Take note of the name: ReHMGB1. A new study pinpoints this protein as being able to spread the wear and tear that comes with time as it quietly travels through the bloodstream. This adds significantly to our understanding of aging. Short for reduced high mobility group box 1, ReHMGB1 triggers senescence in cells, permanently disabling them. It doesn’t just do …
