Solving art's mysteries

A team of researchers used advanced imaging technology to colorize a black-and-white photograph of Matisse's 'Bathers by a River', revealing the artist's innovative methods and palette changes. The resulting image shows how Matisse transformed his work from vibrant colors to somber grays, offering insights into his artistic evolution.

Talking touchscreens aid patients

Multimedia talking touchscreens are helping researchers and clinicians improve communication, knowledge, and adherence to treatment for patients with diverse language skills. The technology provides a more private and accessible way for patients to complete questionnaires and access health information.

Rushing too fast to online learning?

A new study by Northwestern University researchers suggests that online classes may have negative consequences for lower-performing and language minority students. The study found modest evidence that live-only instruction results in higher learning outcomes than internet instruction, particularly for relatively low-achieving students.

Tiny blood vessels in brain spit to survive

Scientists at Northwestern University found that tiny blood vessels in the brain have a unique method of clearing debris by growing a membrane that envelopes the obstruction and then shoves it out. This process is slower in an aging brain, resulting in more capillary death and potentially contributing to age-related cognitive decline.
