Imagine being able to measure your blood sugar levels, know if you’ve had too much to drink, and track your muscle fatigue during a workout, all in one small device worn on your skin. Engineers at the University of California San Diego have developed a prototype of such a wearable that can continuously monitor several health stats—glucose, alcohol, and lactate levels—simultaneously in real-time.

With the world’s population projected to reach ~10 billion in 30 years, scientists are working to use genetic technologies to address future food security problems. They have had some success, such as using CRISPR-Cas9 gene editing process to develop more disease-resistant pigs, but the advance is useless if the pigs cannot be brought to market and if no one will eat their bacon.
