Scientists program proteins to pair exactly

Proteins have now been designed in the lab to zip together in much the same way that DNA molecules zip up to form a double helix. The technique, whose development was led by University of Washington School of Medicine scientists, ...

Engineers repurpose wasp venom as an antibiotic drug

The venom of insects such as wasps and bees is full of compounds that can kill bacteria. Unfortunately, many of these compounds are also toxic for humans, making it impossible to use them as antibiotic drugs.
