Since the 1960s, developmental psychologists point to the "Visual Cliff"—an experiment that plops babies on a fake precipice—as proof that infants learn to fear heights as they learn to crawl. Yet, over the past 25 years, a series of rigorous (and adorable) experiments by Karen Adolph of NYU's Infant Action Lab has shattered this myth, revealing that while babies can learn from experiences near high ledges or narrow bridges, it's not a phobia they acquire.

Michael Musnick is a citizen scientist who studies wood turtles in the Great Swamp -- a stretch of wetland about 60 miles north of New York City. He found turtles dying in the railroad tracks and proposed a solution to New York's Metropolitan Transportation Authority: tiny turtle bridges.

Here's the scoop on coffee's flavor: the taste comes from compounds locked into roasted coffee beans. Add hot water, and those flavors escape into your pot -- but not all flavors escape at the same time, says Harold McGee, food science writer and author of On Food and Cooking. For example, sour flavors, acids, come first and the plant carbohydrates responsible for coffee's body come later. Taste for yourself with this counter-top chemistry experiment.

Male crickets play tunes non-stop to woo a mate or keep enemies away. But they're not playing their song with the body part you're thinking.

Ask most people about crickets and you’ll probably hear that they’re all pretty much the same: just little insects that jump and chirp.

But there are actually dozens of different species of field crickets in the U.S. And because they look so similar, the most common way scientists tell them apart is by the sounds they make.

“When I hear an evening chorus, all I hear are the different species,” said David Weissman, a research associate in entomology at the California Academy of Sciences in San Francisco.

Weissman has spent the last 45 years working to identify all the species of field crickets west of the Mississippi River. In December, he published his findings in the journal Zootaxa, identifying 35 species of field crickets in the western states, including 17 new species. California alone hosts 12 species. But many closely resemble the others. So even for one of the nation’s top experts, telling them apart isn’t a simple task.

“It turns out song is a good way to differentiate,” Weissman said.

--- How do crickets chirp?

On the underside of male crickets’ wings there’s a vein that sticks up covered in tiny microscopic teeth, all in a row. It’s called the file. There's a hard edge on the lower wing called the scraper.

When he rubs his wings together - the scraper on the bottom wing grates across all those little teeth on the top wing. It’s like running your thumb down the teeth of a comb. This process of making sound is called stridulation.

--- How do crickets hear?
Crickets have tiny ears, called tympana on each of their two front legs. They use them to listen for danger and to hear each other calling.

--- Why do crickets chirp?
Crickets have several different types of songs that serve different purposes. The familiar repetitive chirping song is a mating call that male crickets produce to attract females that search for potential mates.

If a female makes physical contact with a male he will typically switch to a second higher-pitched, quieter courtship song.

If instead a male cricket comes in contact with another adult male he will let out an angry-sounding rivalry call to tell his competitor to back off.

POW! BAM! Fruit flies battling like martial arts masters are helping scientists map brain circuits. This research could shed light on human aggression and depression.

* NEW VIDEOS EVERY OTHER TUESDAY! *

Neuroscientist Eric Hoopfer likes to watch animals fight. But these aren’t the kind of fights that could get him arrested – no roosters or pit bulls are involved.

Hoopfer watches fruit flies.

The tiny insects are the size of a pinhead, with big red eyes and iridescent wings. You’ve probably only seen them flying around an overripe piece of fruit.

At the California Institute of Technology, in Pasadena, Hoopfer places pairs of male fruit flies in tiny glass chambers. When they start fighting, they look like martial arts practitioners: They stand face to face and tip each other over; they lunge, roll around and even toss each other, sumo-wrestler style.

But this isn’t about entertainment. Hoopfer is trying to understand how the brain works.

When the aggressive fruit flies at Caltech fight, Hoopfer and his colleagues monitor what parts of their brains the flies are using. The researchers can see clusters of neurons lighting up. In the future, they hope this can help our understanding of conditions that tap into human emotional states, like depression or addiction.

“Flies when they fight, they fight at different intensities. And once they start fighting they continue fighting for a while; this state persists. These are all things that are similar to (human) emotional states,” said Hoopfer. “For example, there’s this scale of emotions where you can be a little bit annoyed and that can scale up to being very angry. If somebody cuts you off in traffic you might get angry and that lasts for a little while. So your emotion lasts longer than the initial stimulus.”

Circuits in our brains that make us stay mad, for example, could hold the key to developing better treatments for mental illness.

“All these neuro-psychiatric disorders, like depression, addiction, schizophrenia, the drugs that we have to treat them, we don’t really understand exactly how they are acting at the level of circuits in the brain,” said Hoopfer. “They help in some cases the symptoms that you want to treat. But they also cause a lot of side effects. So what we’d ideally like are drugs that can act on the specific neurons and circuits in the brain that are responsible for depression and for the symptoms of depression that we want to treat, and not ones that control other things.”


--- What do fruit flies eat?
In the lab, researchers feed fruit flies yeast and apple juice.

--- How do I get rid of fruit flies in my house?
Fruit flies are attracted to ripe fruit and vegetables.
