Gene editing gone wrong: Scientists accidentally create angry hamsters
A team of scientists used gene editing to create what they thought would be a calmer rodent. Instead, the gene-edited rodents were angrier.
This molecule may be the “secret sauce” of exercise — but it won’t work as a pill
Administering Lac-Phe to obese mice significantly lowered their appetite, reduced body fat, and improved glucose tolerance.
Engineers develop nanoparticles that cross the blood-brain barrier
Tested using a new brain tissue model, the particles may be able to deliver chemotherapy drugs to cancer patients.
