No Biological Reason Dads can’t Wake up to a Baby’s Cries

Biology, Evolution, Uncategorized /

A new study challenges the belief that women are biologically more responsive to a baby’s cries at night than men. The findings suggest that the gap in nighttime caregiving stems from social norms rather than biological differences. Often referred to as an “acoustic umbilical cord,” a baby’s cry forms a strong connection with their caregiver,

Was Mars Always Destined to Be Dry? New Study Offers a Fresh Theory

Astronomy, Planetary Science /

One of the biggest mysteries in planetary science is etched into Mars’ landscape. The planet’s vast river-carved canyons reveal it was once warm enough to support flowing liquid water. So how did it transform into the dry, lifeless desert we see today—and why? A new study led by University of Chicago planetary scientist Edwin Kite

Orcas Share Food with Humans as a Way to Build Familiarity

Biology /

Researchers have observed an intriguing behavior in killer whales: they sometimes share their prey with humans. While we can’t ask the whales directly, scientists believe this may be an attempt to form connections with people. In 34 Cases Over Two Decades, Orcas Offered Food to Humans—Often Watching Closely for a Reaction A recent study analyzed

One Brain Scan Can Reveal Your Rate of Aging

Neuroscience, Science /

High school reunions often highlight how differently people age. Some individuals remain mentally sharp and physically active well into their later years, while others begin to experience frailty or memory decline much sooner than anticipated. “The way we age biologically doesn’t always match our chronological age,” said Ahmad Hariri, a psychology and neuroscience professor at

Fossilized Footprints Provide Earliest Evidence of Human Presence in North America

Archaeology, Social /

By applying updated radiocarbon dating techniques to ancient footprints preserved in the gypsum-rich soil of White Sands, researchers have confirmed that humans inhabited North America 23,000 years ago—settling a long-standing debate over their true age. The question of when humans first reached North America has been a topic of ongoing controversy, largely due to debates
