The Scientist spoke with marine biologist and barnacle researcher John Zardus about why turtle barnacles—previously thought to be immobile—in fact slowly travel. He thinks the answer is food.

Research in recent decades has explored how animals other than humans perceive different numbers of objects

The Scientist spoke with Chapman University’s Yu Zeng about his lab’s finding that the slime-producing cells of the slippery marine fish vary with the creature’s size, which may be an adaptation to thwart different predators.

Ethologist Jan Langbein and his team trained the cattle as a way to keep solid and liquid cattle waste separate—with the goal of reducing ammonia emissions coming from livestock.

A full beard can absorb nearly 40 percent of the shock from a punch to the face, according to one winning study.

Leiden University’s Carel ten Cate tracked down 34-year-old duck recordings—and the man who made them—to verify that musk ducks are capable of vocal learning, an ability that hadn’t been thought to exist in waterfowl.

The Princeton University evolutionary biologist studies how animals are changing due to human activity.

A handful of high schoolers prompt scientists to develop a new approach for calculating the size of the ancient behemoth.

Researchers discover surprisingly high levels of genetic diversity among the colorful male morphs of a freshwater fish.

By studying the vocal behavior of 20 baby bats from birth to weaning, researchers have identified striking similarities between how young humans and bats develop communication skills.

Researchers discover that rattlesnakes change their rattling frequency when a perceived threat approaches—tricking humans into thinking the snake is closer than it really is.

The Scientist spoke to marine biologist Tim Lynch, who dusted off 25-year-old data from his PhD to figure out why olive sea snakes approach divers so often. He says the animals, especially the males, likely confuse people for potential mates.

If confirmed, the findings indicate that animals appeared on Earth millions of years earlier than previously believed.

A recent sampling from two California streams found nearly all juvenile salmon were infected with deadly parasites, and conditions are expected to worsen.

Watch one scurry around upside down in a remarkably unusual form of locomotion.

Microscopic creatures called epibionts that live on sea turtles’ shells can help researchers understand their secretive lives.

A population explosion that began late last year has yet to abate. Meanwhile, researchers are exploring novel approaches to combat the nonnative species.

A group of self-styled screamologists are sifting through the noisiness of nonverbal human vocalizations and finding previously undemonstrated forms of communication.

A detailed analysis of cryptochrome 4 shows that the protein is highly sensitive to magnetic fields in vitro, but some researchers dispute the authors’ assertion that the findings could help explain avian magnetoreception.

This evolutionarily ancient fish species has a lifespan that’s around five times longer than previously thought, and a gestation time of more than five years.
