Different methods of drug delivery give us more tools to fight disease Credit: James Olstein Advertisement Covid is credited with propelling clinical innovation. But for a disease that seems to start in people’s noses, none of the available drugs or vaccines are delivered intranasally. Killing the virus before it travels into our lower airways could … Read more

Scientists Simulated 100,000 Different Futures. Which One We Get Depends Only on Us

Most of us have at least one moment in our lives when we wish we’d made a different choice.

Glowing tumor marker may interfere with cancer studies in mice, creating reproducibility problems | Science

Cancer biologist Cyrus Ghajar was gearing up to study how the immune system can fight breast cancer when he hit a snag: The supposedly fast-spreading cancer cells he implanted in mice stayed put and sometimes even disappeared after about 11 days. Then postdoc Candice Grzelak identified the culprit: the green fluorescent protein (GFP) the researchers … Read more
