The Different Types of Obesity and Being Overweight
The difference between the medical definitions of overweight and obesity hinges solely on body mass index (BMI), but experts are beginning to think there are other types of obesity as well.
Brain stimulation may boost long-term, working memory in older adults
About 40% of adults ages 65 and older experience memory loss. Researchers from Boston University have found that applying noninvasive electrical stimulation to certain parts of the brain may help improve long-term and working memory in people over the age of 65 for up to a month.
Dementia: What you do while you sit may affect your risk

Insufficient sleep in teenagers is associated with overweight and obesity

COVID Reinfections Are Now Common. Will Getting a Booster Even Help?
Everyone in the United States knows someone -- often multiple someones -- who have been reinfected with COVID-19. Despite vaccines, boosters and natural immunity, the highly infectious Omicron variant appears capable of getting around whatever protection you might have gained against SARS-CoV-2.
Fat Around the Liver Raises Risk for Heart Failure
About 30% of adults around the world have a buildup of fat in the liver, a condition called nonalcoholic fatty liver disease. Now an international team of researchers has linked that condition to a heightened risk of heart failure.
Obesity: Is the sight or smell of food enough to trigger inflammation in the brain?

At the same time, the pancreas starts to release insulin, ready to deal with the influx of glucose into the blood. This neurally mediated or cephalic phase response has been recognized for some time, but the mechanisms involved were unclear. Now, a study from the University of Basel has shown that a short-term inflammatory response is responsible for this early insulin release.
