Artificial intelligence digitally stains tissue samples used in pathology, saving labor, time and cost

Histopathology is one of the main methods used for diagnosis of disease. Following a medical screening process, a patient can undergo a biopsy, in which a piece of tissue is removed for further inspection and diagnostic analysis. This tissue specimen is then sliced into thin sections that are on the order of a few millionths of a meter in thickness. These thin sections of tissue contain at the microscopic scale the diagnostic information regarding the patient's condition. However, they exhibit almost no contrast under standard light microscopy. To reveal these microscopic features embedded inside tissue and bring visible contrast for inspection by a pathologist, various tissue staining methods have been created in pathology dating back to more than 150 years ago. These tissue staining procedures use different types of colored dyes that specifically label micro-scale structures in tissue, forming colorful images of specimens, which have been widely used as a gold standard diagnostic method in modern medicine.

Generating cross-modal sensory data for robotic visual-tactile perception

Perceiving an object only visually (e.g. on a screen) or only by touching it, can sometimes limit what we are able to infer about it. Human beings, however, have the innate ability to integrate visual and tactile stimuli, leveraging whatever sensory data is available to complete their daily tasks.

Gaining a little weight after quitting tobacco is offset by the benefits for people with diabetes

Two new studies point to yet more reasons to kick the tobacco habit. In one, researchers found quitting smoking is worth it for people with diabetes despite worries about potential weight gain. In the other, scientists discovered smoking might have a much greater impact on the cognitive function than originally thought. Both studies were presented at the American Heart Association's Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2019, a premier global exchange of the latest advances in population-based cardiovascular science for researchers and clinicians, held in Houston this week.
