No one looks forward to getting old; in fact, it can seem pretty scary. But you might be surprised to learn that aging brings some benefits. All things being equal —  given reasonably good health and a secure economic situation — older people tend to be happier than younger people, according to a growing body of research. A widely cited study published in 2016 in the Journal of Clinical Psychiatry looked at more than 1,500 people from 21 to 100 years old and found that mental health increas ...read more

At first glance, they might seem cute, with sleep, spotted coats, floppy forms, and near mischievous-looking smiles, as they haul-out upon land or ice. But put yourself in the shoes – or flippers, rather – of an unfortunate penguin, and you’d see a different side of them: a gaping pink maw, greeting you with long fangs, ready to pierce flesh.While it’s unlikely you’ll ever encounter one of these apex predators unless you find yourself down in the southern hemisphere, leopard seals wiel ...read more

A mosquito-borne parasite, Plasmodium malariae causes malaria — a disease responsible for at least 608,000 deaths and 249 million cases in 2022, according to the World Health Organization. Malaria usually causes severe headaches, fevers, and chills for modern day humans.But according to a new study, ancient humans in the modern-day Arabian Peninsula may have been resistant to the disease. A mutation in DNA most likely happened 5,000 years to 6,000 years ago, or when farming started in Eastern ...read more

The fierce Tyrannosaurus rex is well known for its boxy head, sharp teeth, and petite arms. But why did T. rex have such tiny arms and what did they use them for? Experts have developed various hypotheses for decades. Some say the tiny, seemingly useless appendages, which may have been too small to accomplish anything, might have been well adapted to give other dinosaurs a good slashing from a short distance.Others suspect they were used for holding on to other T. rexes during mating rituals, to ...read more

It’s been just over a century since British archeologist Howard Carter discovered the most prized collection of Egyptian antiquities ever found from within the tomb of King Tutankhamun.

Radioactive decay is ubiquitous. It occurs everywhere on Earth and throughout the universe. The most common forms occur when an unstable nucleus spits out an alpha particle, consisting of two neutrons and two protons, a beta particle consisting of an energetic positron or electron, or a gamma ray, consisting of a high energy photon. When these powerful forms of radiation pass through matter, they strip electrons from atoms and molecules, leaving a trail of charged particles in their wake. Detect ...read more

Anyone who has ever tried to start a campfire knows it’s not that easy — even with matches. A person has to get the right kindling and tinder, place the match in a suitable spot, and nurture the flame so it spreads. It’s no wonder different scouting groups award merit badges to campers who successfully foster the flames.It took a long time for ancient humans to master fire-making and adapt it to daily life. But once fire became a consistent tool, it changed many aspects of early human civi ...read more

Thescelosaurus wouldn’t have known that its world was about to change drastically. More specifically, that a seven-mile-wide asteroid barreling toward Earth would soon end life as we knew it at the time. The Age of Dinosaurs was about to come to an abrupt end.Just before the K-T Event, 66 million years ago, Thescelosaurus would have lived alongside Triceratops, Tyrannosaurus rex, and Ankylosaurus in western North America. The species didn’t have many of the dazzling features like horns, a cl ...read more

But are we hardw ...read more
