As the largest-ever marine predator, the megalodon shark made infamous by Hollywood, measured up to 50 feet in length and was surprisingly warm-blooded, according to a new study published in Proceedings of the National Academy of Sciences. This keen adaptation allowed the “meg” to venture into cold waters and extend its range, but paradoxically, it also bled off crucial energy, which may have contributed to the species’ extinction.Read More: The Mystery of the Megalodon and What Scientists ...read more
Appreciating beauty is part of most people’s everyday lives. We find it in the natural world, in one another, in art and even in ideas. It feels good when we see something beautiful.But this appreciation of beauty presents a slight paradox.Studies on human aesthetic preferences have found that our evaluations of beauty converge on certain features: simplicity, symmetry, juxtapositions of color, and particular shapes, ratios and geometries. And yet, individuals can possess vastly different noti ...read more
Temnothorax nylanderi is a low-key species of ant found mostly in Europe, where it builds nests in tree bark and rotting branches and other woody, secluded places.

These compromised individuals hang out in the nest, not doin ...read more
Most dog owners are familiar with their pups' enthusiasm for food, whether it's begging for a bite, scavenging crumbs or munching on grass.

In fact, their ability to eat a wide variety of foods likely played a major role in making dogs the human companions they are today. However, just because a food doesn’t hurt your pup, doesn’t necessarily m ...read more
Around a decade ago, an astonishing assortment of hominin bones was discovered in the depths of South Africa's Rising Star Cave. Within two years of the discovery, researchers had determined that the bones represented a new species, which they named Homo naledi. Short, stout and small-brained, the species trampled through South Africa between 335,000 and 241,000 years ago and behaved brutishly.Well, that's what most paleoarchaeologists and paleoanthropologists who read about the discovery assume ...read more
