Georgia Tech scientists uncovered how whole-genome duplication emerges and remains stable over thousands of generations of evolution in the lab.  

A UCLA-led team has developed an advanced sensor platform that measures metabolites — key molecules involved in sustaining life through metabolism — inside the body in real time.

By mimicking natural metabolic pathways and using biological molecular toolkits, the sensors can track thousands of metabolites, far beyond the small set detectable by traditional sensors, while simplifying the technology development process.

This advance opens up new possibilities for diagnosing and managing disease, developing new drugs and unlocking deeper insights into how biological systems function. 

Many obese people report losing pleasure in eating rich foods — something also seen in obese mice. UC Berkeley scientists have now discovered the reason. Long-term high-fat diets lower levels of neurotensin in the brain, disrupting the dopamine pleasure network and decreasing the desire to eat high-fat foods. Raising neurotensin levels in mice brings back the pleasure and aids weight loss. Bringing back the pleasure could help people break the habit of overeating.
