Breakthrough: AI and better medicines

Many diseases occur because of defects in particular proteins—the workhorses of every cell. But developing a drug that targets a defective protein requires knowing that protein's shape. Protein shapes have always been difficult to predict. Then in July 2021, a company called DeepMind reported that its software predicted the structures for 98% of human proteins. By the end of 2021, DeepMind says it will publish the shape of 50% of the 280 million nonhuman proteins, up from 0.01%. These breakthroughs are expected to lead to new medicines.

Other ways to lower stubbornly high blood pressure include getting lots of aerobic exercise, eating a plant-based diet that’s low in salt, getting at least seven hours of sleep per night, limiting alcohol, avoiding smoking, and maintaining a healthy weight.

Holiday health hazards

The holidays come with health hazards, such as eating rich food, which can lead to weight gain; drinking too much alcohol and triggering a fast, irregular heartbeat; being stressed, which can weaken the immune system; and being exposed to someone with COVID-19 at a holiday gathering. To stay safe, one should pick only a few days to splurge on holiday foods, and limit quantities; drink only in moderation; ward off stress by exercising regularly, get seven hours of sleep nightly, practice relaxation techniques; and follow the latest guidelines to reduce COVID-19 exposure at holiday gatherings.

Smarter food shopping
