In recent years, very promising anti-obesity drugs have been developed. Despite these successes, there are patients who do not respond to these drugs or suffer from side effects. Therefore, there is still an unmet need for therapies. Researchers have now discovered a small group of nerve cells in the hypothalamus of mouse brains that influence eating behavior and weight gain. This discovery could pave the way for the development of new targeted anti-obesity drugs.

The new framework expands the assessment beyond immediate clinical symptoms. Added criteria would include biomarkers, CT and MRI scans, and factors, such as other medical conditions and how the trauma occurred.

Unlike traditional painkillers that trigger multiple brain pathways—and often addiction—SBI-810 activates just one specific pathway tied to pain relief, sidestepping the euphoric high, constipation, and tolerance buildup common with opioids. It worked impressively in mice, reducing pain from surgery, fractures, and nerve damage—sometimes outperforming even hospital-grade opioids and gabapentin. Even better, it made opioids more effective at lower doses when used together.

Even subtle forms -- like exclusion from group chats -- can trigger PTSD-level distress. Nearly 90% of teens experienced some form of cyberbullying, accounting for 32% of the variation in trauma symptoms. Indirect harassment was most common, with more than half reporting hurtful comments, rumors or deliberate exclusion. What mattered most was the overall amount of cyberbullying: the more often a student was targeted, the more trauma symptoms they showed.
