The fascinating maths and economics of slot machines

Traditional slot machines used to pay out on 3% of spins, but those manufactured today return at a rate of 45%, according to an article by Andrew Thompson in the Verge.

That’s not down to the generosity of manufacturers but can be explained by psychology and goes back to an experiment by BF Skinner, …

Revealed: The Ocean's Tiniest Life At The Bottom Of The Food Chain

What's at the bottom of the bottom of the food chain? Well, think small ... smaller than you can see.

Tiny life forms in the ocean, too small for the naked eye to see.

There are (and scientists have done the math) trillions of microorganisms in the ocean: plankton, bacteria, krill (they're maybe …

A New Approach for Moving Robotic Arms With the Brain

More than a decade ago, Erik Sorto, 34, was paralyzed after a gunshot wound to the neck. Now, using a robotic arm that he controls with his brain, he can pick up a drink and bring it to his lips in one smooth motion.

But unlike other experimental robotic arms, this one relies on signals sent from a …

HIV immunity: rare gene differences offer hope for treatment

“I believe it’s possible to develop a mass-market single-shot treatment for HIV,” says Dr Gero Hütter. “If we can overcome a few problems, our approach is closer to a complete cure than anything in the last 30 years.”

It’s now seven years since Hütter and his team at the Charité hospital in Berlin …

New for brain scientists: a census of neurons

The human brain is a noisy, busy place, teeming with diversity. To produce the wondrously complex mammalian behavior we take for granted every minute, cells of different sizes, shapes and chemical affinities buzz, hum, crackle and pop in conflict and cooperation with one another.

When everything is …

In a First, a Fish Is Shown to Be Fully Warm-Blooded

The moonfish, or opah, is the first fish shown to be fully warm-blooded, researchers report in the journal Science. Although some large predatory fish, like tuna, can temporarily warm their muscles or organs, the opah is the only fish that warms its heart. A silvery fish the size of an automobile …
