Why do you doubt your senses?”

“Because,” said Scrooge, “a little thing affects them. A slight disorder of the stomach makes them cheats. You may be an undigested bit of beef, a blot of mustard, a crumb of cheese, a fragment of an underdone potato. There’s more of gravy than of grave about you, whatever you are!”

If you’re looking for a strange sea creature, you can’t get much weirder than the giant pyrosome. With an appearance like a monster out of a science fiction movie, those who’ve had the good luck to see them have likened them to everything from unicorns, due to their rareness, to the Borg, because of how they stick together and seem to be part of a collective.

You probably think your dog is pretty smart. And you may be right. Dogs sometimes seem to be able to read our minds, knowing exactly what we’re thinking and what we’re going to do before it’s even clear to us. However, recent research indicates that their wild ancestor, the wolf, may have an edge in some intelligence competitions. [Read more…]

Want to Prevent Algal Blooms? Toilet Train Birds

While they may not be the sole cause, recent research shows that an increase in the population of cormorants on a lake in South Korea may have contributed to algal blooms.(Photo credit: EAGiven/iStock/Getty Images Plus/Getty Images)

Algal blooms are a rapid increase in the population of algae in a body of water. They are characterized by their bright green color. While they can be an entirely natural phenomenon, algal blooms can be very harmful. They can deplete lakes of oxygen, produce toxins, and ultimately kill much of the aquatic life. [Read more…]

A Breath of Fresh Fructose?

Described by some as looking like “bratwurst with teeth,” naked mole rats live in communities with social structures resembling beehives, are coldblooded like reptiles, and now are known to get energy from fructose, like a plant. (Photo credit: Ger Bosma/Alamy)

It’s difficult to find an odder animal than the naked mole rat (Heterosphalus glaber). A native of east African deserts, these mammals live more like bees, in complex, underground societies complete with a queen who gives birth to worker offspring who will never reproduce.  [Read more…]

Stammering speech, or stuttering, has traditionally been thought to be an indication of anxiety or stress. A large amount of evidence, however, has long supported the idea that it must have some genetic component. For instance, identical twins often both stutter, as do other family members. In 2008, scientists at the National Institute of Deafness and Other Communication Disorders identified that those who stuttered often had a mutation in the gene Gnptab. The discovery was particularly interesting, because, previously, the gene had only been believed to be related to “general housekeeping” of the body, such as digestion. How could a gene that affects every cell of the body cause something so mechanical as stuttering? [Read more…]

As senses go, touch might be the least understood. While touch-associated maladies do exist, we don’t often read about sufferers from them. A team of researchers at the Scripps Research Institute spent decades looking into how organisms perceive changes in temperature and pressure. [Read more…]

In cartoons, a sawfish could find itself being unwittingly plucked from the water to serve as a handy tool for any number of purposes. In reality, the long, sharp-toothed snouts of these shark relatives are found to be something much more than an appendage reminiscent of a handsaw. [Read more…]
