A species of remipede known from the Caicos Islands. The photograph was taken by a member of a multinational team looking for rare species. Remipedes are crustaceans that are close relatives to insects.

You Might Think of Shrimp as Bugs of the Sea. But a Remarkable Discovery Shows the Opposite: Bugs Are Actually Shrimp of the Land

A recent study suggests that insects branched out from crustaceans on the tree of life

Romulus and Remus, pups that the company Colossal Biosciences says are the first dire wolves to roam the planet in several thousand years, are seen at one month old.

Have Dire Wolves, Which Went Extinct More Than 10,000 Years Ago, Really Been Brought Back to Life?

Pioneers in the science of “de-extinction,” an American company has announced the births of three pups whose genes resemble those of a species that hasn’t roamed Earth for millennia

Glenn Hodak, a corporal in the U.S. Army Air Forces, has been accounted for nearly 80 years after he died in a fire at the Tokyo Military Prison in 1945.

Remains of American Soldier Captured by the Japanese During World War II Identified Nearly 80 Years Later

After his plane was shot down, Glenn H. Hodak was sent to a military prison in Tokyo, where he was killed by U.S. firebombing in May 1945

The animals were likely gifted to some elites, then spread throughout the region

Scientists used fragments of the child's right forearm bone to date the skeletal remains.

Mysterious Skeleton of Child With Human and Neanderthal Traits Has Finally Been Dated by Archaeologists

Discovered in Portugal in 1998, the individual dubbed the “Lapedo Child” has long perplexed scientists, thanks to a curious mix of features

Researchers studied the impact of extreme heat on older adults' "epigenetic clocks," which measure aging-related changes to DNA.

Extreme Heat Could Make Older Adults Age Faster by Altering Their DNA, Study Finds

Researchers compared genetic markers of aging to daily temperature records in areas across the United States and found that elderly people exposed to more hot days showed more rapid biological aging
