We human beings are quite fond of our brains. They are one of our largest and most complex organs, weighing in at nearly three pounds (2% of our bodies!). Each contains upwards of 90 billion neurons responsible for controlling our gangly, almost hairless primate bodies as well as processing and storing a lifetime's worth of events, facts and figures. So we protect our brains as best we can, from hats that battle temperature extremes to helmets that buffer even the most brutish blo ...read more
The man-eaters of Tsavo, two lions that killed railroad workers in Kenya more than a century ago, have inspired legends, movies and a lot of research papers trying to explain what drove the big cats to prey on humans (a rare menu choice for Panthera leo). A study out today finds that, in one crucial way, the infamous killers were a lot like — surprise — zoo animals.
For years, the true story of the man-eaters of Tsavo has been embellished and exaggerated, most recently in the 1 ...read more
The home planet just experienced its second warmest March on record, according to an analysis released by NASA last week. The agency's temperature records go all the way back to 1880
From the analysis:
Last month was 1.12 degrees Celsius warmer than the mean March temperature from 1951-1980. The two top March temperature anomalies have occurred during the past two years.
Here's how the year so far compares with the seasonal cycle for every year since 1880:
It's still early in the ...read more
A peptide secreted by a species of Indian frog can destroy variants of the influenza virus.
Frogs, with little defensive weaponry to rely on, have armed themselves with a chemical arsenal that gets leached out through their skins. In some frogs, this takes the form of deadly poisons; in others, the chemicals have been known to possess psychoactive properties. Hydrophylax bahuvistara, a species of fungoid frog found in India, secretes a substance that protects against viruses.

Twitter’s been on fire with people amazed by cats that seem compelled to park themselves in squares of tape marked out on the floor. These felines appear powerless to resist the call of the #CatSquare.
This social media fascination is a variation on a question I heard over and over as a panelist on Animal Planet’s “America’s Cutest Pets” series. I was asked to watch video after video of cats climbing into cardboard boxes, suitcases, sinks, plastic storage bins, cu ...read more
Be glad our species wasn't around some 400 million years ago...we would have had to contend with giant sea scorpions, some more than 10 feet in length and capable of prowling about on land in search of a meal. And that's not all: Researchers reveal that at least one of these Monsters of Deep Time had a particularly violent — and unusual — way of dispatching its prey.
Published today in The American Naturalist, the spine-tingling tale of a stabby sea scorpion is ...read more
But in reality, it is a flying saucer moon named Atlas
Who knew? I certainly didn't... Saturn has a moon shaped eerily like a flying saucer.
Check it out in the image above, acquired by NASA's Cassini spacecraft on April 12, 2017 during a flyby that came as close as 7,000 miles from the moon.
This is the closest image ever taken of the moon, named Atlas, according to NASA. The object is just 19 miles across; it orbits Saturn just outside the giant planet's A ring —& ...read more
The equatorial Pacific Ocean is suffering from a split personality disorder: El Niño-ish in the east; La Niña-ish to the west. El Niño is likely to win out.
Climate forecast models are predicting a full-fledged El Niño by summer or fall. If it should happen, it would bring all manner of disruption to global weather patterns.
And it would also be an extraordinary event.
If you'll recall, in 2015-16, the planet experienced a monster El Niño event, one of the ...read more
You've likely seen some version of this scenario on television or in the halls of a university: A researcher runs out of the lab in a frenzy, electrified after suddenly arriving at the solution to an impossible problem. These "aha!" moments are supremely satisfying, whether you're a scientist, a hard-bitten detective or an unlucky horror movie actress realizing that something's just not right.
But what happens to us in the moments just before the light bulb turns on? New research from ...read more
In a thought-provoking new paper called What are neural correlates neural correlates of?, NYU sociologist Gabriel Abend argues that neuroscientists need to pay more attention to philosophy, social science, and the humanities.
Abend's main argument is that if we are to study the neural correlates or neural basis of a certain phenomenon, we must first define that phenomenon and know how to identify instances of it.
Sometimes, this identification is straightforward: in a study of brai ...read more
