As “Cats & Dogs: The Revenge of Kitty Galore” hits the big screen, find out what science has to say about the intelligence and abilities of our favorite household pets.
A guy who can shed a tear really can drive females wild—among mice, at least.
According to a new study, male mouse tears contain a sex pheromone called ESP1, which makes female mice more receptive to mounting.
Our leftover medicines are spawning drug-resistant “bacterial monsters” that thrive inside sharks, scientists say.
The finding suggests antibiotics such as penicillin may be leaching into the environment and spurring drug-resistant bacteria to evolve and multiply in the oceans.
Tiny balls of fungus and feces may disprove the theory that a huge space rock exploded over North America about 12,900 years ago, triggering a thousand-year cold snap, according to a new study.
The ancient temperature drop, called the Younger Dryas, has been well documented in the geologic record, including soil and ice core samples.
The cool-down also coincides with the extinction of mammoths and other Ice Age mammals in North America, and it’s thought to have spurred our hunter-gatherer ancestors in the Middle East to adopt an agricultural lifestyle.
Some gangs of chimpanzees beat their neighbors to death in bids to expand their turf, according to a new study.
While scientists have long known that chimps will kill each other on occasion, the finding shores up a long-held hypothesis that humans’ closest living relatives sometimes turn to violence to annex valuable parcels of land.
The first vertebrates to walk the Earth emerged from the sea almost 20 million years earlier than previously thought, say scientists who have discovered footprints from an 8-foot-long (2.4-meter-long) prehistoric creature.
Dozens of the 395-million-year-old fossil footprints were recently discovered on a former marine tidal flat or lagoon in southeastern Poland.
A decade ago, global climate change was largely considered a problem for the distant future. But it seems that future has come sooner than predicted.
One of the most remarkable, and alarming, environmental changes to occur over the last decade is the melting of Antarctic ice sheets and the recession of Arctic glaciers at speeds much faster than climate change models had predicted, according to environment experts.
