Researchers from HIT Shenzhen have developed a magnetic capsule robot that can take internal samples non-invasively by swallowing a pill with a controllable magnetic mechanism, which opens to collect samples and is later expelled naturally; animal trials are upcoming.
Excess skin sagging after weight loss can be a common concern, but there are treatment options available. While at-home creams may not be effective, non-invasive procedures like ultrasound, radiofrequency, and laser treatments can stimulate collagen production and tighten the skin. Surgical procedures such as tummy tucks, lower body lifts, panniculectomy, thigh and buttock lifts, and upper body lifts can also remove excess skin. Consulting with a medical professional can help determine the best course of action for tightening loose skin after weight loss.
