Bite force is the amount of pressure and force in an animal’s bite. It’s measured in psi (pounds per square inch). But no matter the unit of measurement when these mega-predators chomp down, you’d better hope you’re not on the receiving end of it. Just to give you some perspective, the bite force of a measly human is just 162 psi. Here are some animals with the strongest bite force. 1.

After delivering a guest lecture on sticklebacks, an unfamiliar fish caught Stanford University researcher David Kingsley’s eye. When he walked past an aquarium at the Woods Hole Marine Biology Laboratory, a strange aquatic creature stopped him in his tracks.“I did this huge double take because I looked in this one tank, and there was one of the weirdest fish I've ever seen,” says Kingsley. “It had the body of a fish, the wings of a bird, and it was walking along the bottom of the tank o ...read more
Under warm summer conditions, the sea ice stretching across much of the Arctic Ocean shriveled much more dramatically than it did during cooler summers of decades past, the National Snow and Ice Data Center has reported."While it wasn’t a new record low, this year’s sea ice minimum is yet another example of a changed Arctic environment," said Walt Meier, an NSIDC senior research scientist.Every year, the Arctic's floating sea ice shrinks under summer warmth, typically reaching a minimum exte ...read more
The mournful eyes, the lingering stares, the sad sighs. Many pet parents leave the house each day with a dog or cat watching somberly from the window.Social scientists have found that pet owners experience ongoing guilt about wanting to do better for their animals. Researchers have called it an understudied topic that needs to be better considered, particularly as more workers are called back into the office full-time. Why Owners Feel Guilty About Leaving Their PetsPsychologist Lori Kogan felt ...read more
The human mind is unlike any other. It’s the key that unlocked language, culture, abstract reasoning, long-term planning, and large-scale political coordination — all the cognitive features that set us so far apart from the rest of the animal kingdom. It need not diminish other creatures’ intelligence to describe ourselves, in the words of British psychologist Cecilia Heyes, as “animals that specialize in thinking and knowing.”Yet, in another sense, we aren’t so separate from the res ...read more

Many wonder how birds migrate vast distances. A study in the Proceedings of the National Academy of Sciences investigates that and also looks into the “where,” “when,” and “why” of avian travel. They found that birds flock to drastically different environmental conditions that meet different needs over the course of a year.Crane TrackingResearchers affixed GPS tracking devices to the legs of 104 cranes in Africa, Asia, and Europe. They learned that some cranes traveled nearly 4,000 m ...read more
Some jokes are like a fine wine and age well with time; others get rather lost in translation as the centuries pass. One joke, etched in the ancient cuneiform writing of the Sumerian people, stands as the oldest recorded bar joke and dates back roughly 4,000 years. It reads: “A dog walks in a bar and says, ‘I cannot see a thing. I’ll open this one.” Surely, this joke was hilarious in its time, but today, this nonsensical one-liner has sparked much debate and theories about why exactly it ...read more
