The egg of the future may not involve a chicken at all. In fact, in the high-tech food lab at Hampton Creek Foods in San Francisco, the chicken-less egg substitute has already been hatched.

In the wake of the 439 comments on my last post about obesity and weight-bias in our society, I've been thinking about issues of comparative health around the world and, as I have before, about the Paleo diet.

What Bird Flocks And Fish Schools Can Teach Us About The Future

NEAL CONAN, HOST:

This is TALK OF THE NATION. I'm Neal Conan.

We've all seen a flock of birds shift direction instantaneously mid-flight, or a school of fish swirl in what looked like tightly choreographed maneuvers. That's called collective behavior and it fascinated and baffled scientists. Why do they do it? How? Telepathy? Now technology is revolutionizing the way researchers can track, visualize and even create swarms, and what they're finding will make you go wow.

Prevention Pill Cuts HIV Risk For Injecting Drug Users

The Centers for Disease Control and Prevention says doctors should prescribe Truvada, a once-a-day pill for HIV, to help prevent infections in IV drug users.
Jeff Chiu AP

A once-a-day pill has been proven to lower the risk of getting HIV among needle-using drug addicts, just as it does among heterosexual couples and men who have sex with men.

Among 2,400 injecting drug users in Bangkok, those assigned to take a daily dose of an antiviral drug Viread, or tenofovir generically, had half the risk of getting HIV over a four-year period as those who took a placebo pill. Among those who took tenofovir faithfully, there were 74 percent fewer infections.

Why Dolphins Make Us Nervous

Robert Krulwich NPR

What is it about dolphins? They have very, very big brains, and that makes we humans, whose brains are nothing to sniff at, nervous. We don't know what to make of them.

The latest example: On May 17 in India, the Ministry of Environment and Forests issued an order to all Indian states banning dolphin amusement parks. No leaping out of pools to catch balls, no jumping through hoops. Forcing dolphins to entertain humans, the ministry said, was morally unacceptable.

Fancy Feet: Wild Cheetahs Excel At Acceleration

Nature documentaries always go on and on about how fast a cheetah can run. Cats in captivity have been clocked at 65 miles an hour, the highest speed recorded for any land animal.

And yet, scientists know very little about how the animal runs in the wild, especially when on the hunt.

"You can look at it and say, 'Oh that's fast,' " says Alan Wilson, a veterinarian at the Royal Veterinary College, London. "But you can't actually describe what route it follows, or how quickly it's gone, or the details of [the] forces it has to exert to do that."

The connected car promises voice-activated systems that let drivers dictate emails and texts, make a dinner reservation or update their Facebook page, all while behind the wheel. Some cars already have these options. Many more are on the way. Carmakers say it's safer than fiddling around with a smartphone.

Chopped: How Amputated Fingertips Sometimes Grow Back

A little bit of nail can help a fingertip regrow.
Heather Rousseau NPR

When a kid lops off a fingertip with a cleaver or car door, there's a chance the end of the digit will grow back. The fingerprint will be gone, and the tip may look a bit strange. But the flesh, bone and nail could return.

Now biologists at New York University have figured out just how this lizard-like regeneration happens in mice. There's some secret sauce at the nail cuticle that makes it possible, scientists report Wednesday in the journal Nature.
