The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Extended course of Paxlovid shows promise for some long Covid patients

An up-close look at how patients respond to the drug at different times and doses adds nuance to a recent finding that Paxlovid does not work for long Covid.

Addressing barriers to healthcare delivery for people with Alzheimer's disease and related dementias

Kosali Simon, PhD, M.A., a professor with the Paul H. O'Neill School of Public and Environmental Affairs and a Regenstrief Institute research scientist; and Katherine Baicker, PhD, University of Chicago provost, will co-lead an expected nearly $16 million National Institutes of Health's (NIH) National Institute on Aging (NIA) program to explore critical aspects of healthcare delivery for individuals living with Alzheimer's disease and related dementias (ADRD).

Researchers grow tumor organoids from blood to tackle breast cancer metastasis

Tumor cells circulating in the blood are the "germ cells" of breast cancer metastases. They are very rare and could not be propagated in the culture dish until now, which made research into therapy resistance difficult.
