For the first time ever, scientists have successfully sequenced the full genome of an individual who lived in ancient Egypt as far back as 4,800 years ago—during the era when the first pyramids were under construction. The genome comes from an older male, likely a member of the elite class. Based on his genetic markers, […]

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,

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

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

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

If you’re hoping to fit in more exercise tomorrow, going to bed earlier tonight might make a difference, according to a new study that explored how bedtime habits relate to physical activity the next day. Conducted by researchers at Monash University in Australia, the study doesn’t claim that earlier bedtimes directly cause increased exercise, but it

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

Had 19th-century scientists possessed today’s advanced atmospheric tools, they might have detected the earliest signs of climate change caused by human activity—specifically, the burning of coal and wood. Scientists Suggest Climate Change Could Have Been Detected as Early as 1885 In a recent thought experiment, a group of Earth and atmospheric scientists concluded that, with

Virginia might have a new partner in battling one of its most destructive insect pests. Researchers at Virginia Tech, led by Assistant Professor Scotty Yang from the Department of Entomology, have discovered a method to use ants to detect the presence of spotted lanternflies in new regions. Published in Pest Management Science and Neobiota, new
