A proposed dinosaur family tree rewrite may sound like a crazy idea, but remember, not that long ago scientists thought Iguanodon looked like this (hint: we know better now). (Credit Samuel Griswold Goodrich/Illustrated Natural History of the Animal Kingdom, 1859)
Earlier this year, a trio of paleontologists led the charge to rewrite the most fundamental thing we believe about dinosaurs. Their call to action generated controversy and, more importantly, serious academic discussion. Now, a b ...read more

For years, experts thought Alzheimer’s, a progressive neurodegenerative disease, originated in the brain. After all, it’s the organ that takes the beating: Proteins build up in the brain, forming plaques or tangles that can damage cell function.
And depending on which hypothesis you’re reading up on, the critical damage that kick-starts symptoms comes from either beta-amyloid proteins, the traditional suspects, or tau proteins, a relatively new but incr ...read more

Few groups of animals are as feared as spiders. Doctors estimate at least 5% of people are arachnophobic, meaning they are terrified of the eight-legged critters. But such fear is largely misplaced. Of the nearly 47,000 species of spider on the planet, only 200 or so can actually bite through our tough skin and deliver venom that causes any kind of reaction. And of those, onl ...read more

To be human is to be curious. Our constant interrogation of the world around us has led to pretty much every bit of knowledge we hold as a species. This is what scientists do, through carefully controlled experiments and quantitative data collection. Some questions, though, have been deemed too dangerous, or too foolish to pursue. What’s a passionate scientist to do when society frowns upon their research? Put themselves under the ...read more
With many of us spending our time online, we tend to be laser-focused on preventing our personal information from falling into the hands of nefarious hackers. But let’s not forget about the security of print-based communications.
Remember how the ink appears and disappears on the Marauder’s Map that appears in Harry Potter and the Prisoner of Azkaban? Basically, scientists are trying to recreate this bit of magic to protect information. But instead of using a password to make t ...read more

The mysteries surrounding black holes make for some fascinating research. Whether consuming dead stars or anchoring baby galaxies, black holes are one of the most perplexing astronomical phenomena. Especially when they shoot out jets of supercharged plasma akin to Star Wars’ world-destroying Death Star superlaser.
These streams of plasma are known as relativistic jets, an ...read more

Humans in North America only spend one night a year in costume with the hopes of feasting on tasty treats. For Zodarion spiders, that’s just called Tuesday. These clever mimics pretend to be ants to sneak close to their prey. And if in danger, they’ll use the corpse of their latest capture to complete the charade.
The spiders in the genus Zodarion are ant specialists&mdas ...read more
Earlier this month, a guard patrolling a Guatemalan wildlife reserve photographed a young salamander. Its glossy orange-and-black skin made it look like a Halloween decoration. But the salamander’s appearance wasn’t just seasonally appropriate—it was the first time anyone had laid eyes on the species in 42 years.
Two Americans first discovered Jackson’s climbing salamander (Bolitoglossa jacksoni) while hiking in the cloud forests in 1975. Its name came from one ...read more

In 1207 BCE, as an army of Israelites waged a bitter conflict against soldiers from Canaan, the sun all but disappeared. The event had all the markings of divine intervention, and the auspicious occurrence would go on to be recorded in the Old Testament. Today, eclipses have lost the aura of religious significance, but this particular occasion was special. It’s the first time we can confirm that an eclipse was ever recorded for posterity, say researchers fro ...read more
