Researchers at Imperial College London have designed a microchip technology that they say may help curb the obesity problem in developed nations. The chip, which presently is being tested in animals, is implanted in the gut, where it sends satiation signals to the brain. The researchers project that they will begin tests in patients in three to four years.

Of mice and men. A team from the Cleveland Clinic used animal and human studies to accumulate evidence that challenges conventional wisdom on red meat and cardiovascular disease. Red meat is still on the hook, but the culprit appears to be a byproduct of bacteria involved in the digestion of red meat. The New York Times describes the multiyear effort, including results published in Nature Medicine.

Cholesterol may play a role in the development of macular degeneration, according to a study published online in Cell Metabolism.

Decision trees sometimes overshadow clinical decision making, but physicians and patients can counter that trend with an emphasis on personalized medicine. That is the thesis of the book “When Doctors Don’t Listen: How to Avoid Misdiagnoses and Unnecessary Tests,” which was reviewed in the New York Times.
