You are likely quite familiar with the sound of birds singing. You might have also heard the sounds of frogs singing a chorus around a pond or lake. But did you know that some mice sing too? What is the reason behind this unusual behavior? [Read more…]

What Wombats Leave Behind

Let’s be honest, poop is kind of gross. It’s not something normally discussed in polite company. Yet, we can all agree it serves a purpose. Beyond the obvious purpose of eliminating wastes, what organisms excrete also can help both human and animal doctors diagnose illnesses and assess the general health of a patient. In the wild, “scat,” as it’s often referred to, has even greater significance. [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…]

Convinced Your Dog is Smart? You Might Be Right

Humans have long recognized the alertness, trainability, and friendly temperament of many dog breeds and pressed them into service for such very personal tasks as serving as trusted guides for the visually impaired. New research out of Hungary shows that dogs may possess an even more beautiful mind the previously thought.(Photo credit: bobbymn/iStockphoto.com)

If you have a dog, you probably think yours is the smartest dog in the world. New research from Hungary just may prove you’re correct. [Read more…]

I Am Mouse, Hear Me Roar

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…]

It’s a disgusting way to live, but dung beetles do it … and thereby deserve their unenviable name. Males of the species seek out steaming piles of manure, descend on them, shape some of the smelly stuff into balls, and roll them away from chaos of the pile, hopefully attracting a mate along the way.
