Europe has surprisingly little genetic variety. Learning how and when the modern gene-pool came together has been a long journey. But thanks to new technological advances a picture is slowly coming together of repeated colonization by peoples from the east with more efficient lifestyles. »
Meet the muntjac — the most interesting deer in the world. It’s the size of a dog, it’s the oldest deer around, it has antlers but fights with tusks, and it even barks loudly at things that threaten it. But its most interesting quality is this — it gets by with fewer chromosomes than any other mammal on Earth. »
Maybe you grew so fast it left stretch marks on your legs. Or your voice started cracking every time you got on the phone. Or you hated needing to wear a bra. Growing up means going through puberty. It’s an integral part of becoming an adult. But we still don’t know how our bodies start the process. »
A team of geneticists is ready to unlock the secrets behind Internet celebrity cat Lil Bub’s unique appearance.
Earlier this month, a change was made to New Zealand’s Animal Welfare Amendment Bill stating that animals — like humans — are “sentient” beings. »
An international team of scientists have isolated a gene within the Aedes aegypti mosquito that partially transforms females into males. Since only females spread diseases by feasting on human blood, the discovery could lead to powerful population control strategies.
Fisheries biologist John Shepherd once said that “counting fish is like counting trees—except you can’t see them and they move.” This can make animal behavior research extremely difficult. And while increasingly advanced electronic telemetry tags can tell us a lot, there’s just no substitute for seeing a behavior on… »
You were once as wrapped as snug as the pony in the picture. Before you were born, you sat wrapped inside a placenta tucked inside your mother’s womb. That placenta was the very first reproductive structure your body built, long before you built your testes or ovaries or genitalia. »
The quick and dirty route to gaining strength is to take some kind of anabolic steroid. These drugs actually trick the body into building up muscle mass and endurance — but they can also age you far beyond your years. »
One of the biggest challenges for scientists studying the anatomy and physiology of genitalia is the fact that much of the real functional action happens deep inside females. It’s hard to see what’s going on in there. That’s why I love studies that rise to the challenge of giving us a peek inside. »
Beverly Joubert and her husband Dereck are spearheading a relocation project, called Rhinos Without Borders, that aims to move 100 rhinos from poaching hotspots in South Africa to safer parks in Botswana. It’s the largest rhino airlift ever attempted, and the first ten transportees have been successfully released. »
Fishermen working off the coast of Plymouth in Britain snagged a 7-foot-long (2.1 meters) conger eel by mistake after it got tangled in their nets. Weighing in at just over 133 pounds (59 kg), it’s a near-record catch — but this clever optical illusion makes it look much longer than it really is. »
When the fossil of this 12 million year old whale with a terrifying set of giant jaws was uncovered the name chosen was a fitting one: Leviathan, for the Biblical sea monster, and Melvillei, for the author of the most famous whale story. And then things started to get tricky. »
Of all the fish in the world, only a few have the capacity to maintain warmth in specific parts of their bodies. But as new research reveals, the deepwater opah has the unprecedented ability to circulate heated blood throughout its entire body, making it the only known fully warm-blooded fish. »
As much as I’m looking forward to Jurassic Park, I will never quite forgive dinosaurs for the sin of being birdlike. How can I fear something that I eat in nugget form? Now prehistoric mammals — that’s where the action is. Here are the top 10 mammals that ruled more than any dinosaur ever. »
Scientists have shown that body-flinging escape jumps by trap-jaw ants are more than just a neat insectoid party trick.
Here’s a great Charles Darwin story you may not have heard before: In 1862, the famed naturalist foretold the discovery of an unusual animal, based on his observations of a species of orchid endemic to Madagascar. The creature was ultimately discovered in 1903—some 20 years after Darwin’s death. »
Many popular exercises are performed incorrectly, often by people who probably shouldn’t be attempting them in the first place. This can result in injuries and futility at the gym. We talked to the experts to find out which exercises are the most problematic, and how to do them correctly. »
