A nearly decade-long study from the National Bureau of Economic Research looked at births in California. The study found that babies born to the richest Black women were still more likely to die than babies born to the poorest White women.

When you don’t get enough good sleep, the short-term consequences are noticeable — maybe you’re distracted at work or snappy with loved ones. But in the background, irregular and poor-quality sleeping patterns could increase your risk for developing cardiovascular disease, according to a new study.

A robot nicknamed Icefin operates under the sea ice near McMurdo Station in Antarctica in 2020. The pencil-shaped robot is giving scientists their first look at the forces eating away at the Thwaites glacier. (Schmidt / Lawrence / Icefin/ NASA PSTAR RISE UP via AP)

Using a 13-foot pencil-shaped robot that swam under the grounding line where ice first juts over the sea, scientists saw a shimmery critical point in Thwaites’ chaotic breakup, “where it’s melting so quickly there, there’s just material streaming out of the glacier.”

You might call Dan O’Conor an amateur authority on cold water immersion. Since June 2020, the 55-year-old Chicago man has plunged into Lake Michigan almost daily, including on frigid winter mornings when he has to shovel through the ice.

Cancer risk and mortality, especially for ovarian cancer, rose as more ultra-processed foods were eaten, a new study found. (Adobe Stock)

Researchers examined information on the eating habits of people who were part of the UK Biobank, a large biomedical database. Eating patterns were then compared with medical records that listed both diagnoses and deaths from cancer.

With animal fossils hard to come by, the researchers extracted environmental DNA, also known as eDNA, from soil samples. This is the genetic material that organisms shed into their surroundings — for example, through hair, waste, spit or decomposing carcasses.

Japanese drugmaker Eisai and its U.S. partner Biogen had announced earlier this fall that the drug lecanemab appeared to work, a badly needed bright spot after repeated disappointments in the quest for better treatments of the incurable disease.

Zombie or doomed ice is ice that is still attached to thicker areas of ice, but is no longer getting fed by those larger glaciers. Meanwhile the doomed ice is melting from climate change, said study co-author William Colgan, a glaciologist at the Geological Survey of Denmark and Greenland.

The Alzheimer’s Association reports that among Black Americans age 70 and older, more than 21% are living with that disease. Pharmaceutical company Eli Lilly is launching a clinical trial of a new drug therapy for those at risk, and they’re looking for participants in Chicago.

After noticing changes in their menstrual cycles after getting a COVID-19 vaccine, a pair of researchers surveyed others about their experiences. A new analysis of over 35,000 responses finds many experienced changes to their periods, including unexpected bleeding.

More than 30 years ago, a group of Northwestern University medical students started a youth development program with the goal of improving the lives of children living in poverty. New research finds one such program that provided youth with long-term support is associated with reduced poverty in early adult life.

A new Northwestern Medicine study of 52 long haulers, who were not hospitalized and only experienced mild symptoms like cough and sore throat, found that most continued to experience neurologic symptoms, fatigue and compromised quality of life up to 18 months after initial infection.

Nearly 40 cities across the country are recruiting 4,000 young adults ages 25-35 to participate in a study that will track and analyze their lung health over their lifetime to better understand how environment, lifestyle and physical activity impact respiratory health.
