Amazon One lets users enter and pay for items in stores by swiping their hand over a kiosk.

Gene editing insects could help reduce reliance on pesticides—and help protect billion-dollar industries.

Amazon announced Thursday it is rolling out its pay-by-palm services in Whole Foods Market stores across the country, making it possible for customers to use their palms for purchases without a wallet or phone.

The palm recognition service, called Amazon One, will be available for payment and Prime membership benefits in all Whole Foods Market locations by the end of this year. Instead of traditional payment methods, Amazon One allows customers to hover their palm over an Amazon One device.

Customers who link their Prime membership with their Amazon One profile will also automatically receive savings once their palm is registered, according to the Seattle-based retail giant.

Amino acids serve as the foundational elements of proteins, vital to the optimal functioning of biological structures. Proteins in all life forms are composed of 20 core amino acids.

<div class=””> <div class=””><br />Amino acids are a set of organic compounds used to build proteins. There are about 500 naturally occurring known amino acids, though only 20 appear in the genetic code. Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active. The amino acid sequences of proteins are encoded in the genes. Nine proteinogenic amino acids are called “essential” for humans because they cannot be produced from other compounds by the human body and so must be taken in as food.<br /></div> </div>

Sometime during the Cretaceous Period, 125 million years ago, a feisty mammal the size of a domestic cat encountered a dinosaur three times its size and thought it looked like a tasty meal.

A fossil unearthed in northeastern China captures the two creatures — a badgerlike animal called Repenomamus robustus and a species of plant-eating dinosaur known as Psittacosaurus — forever locked in mortal combat.

It’s a dramatic instant in time that challenges the idea that the earliest mammals lived in the shadows of dinosaurs, said paleobiologist Jordan Mallon, a research scientist at the Canadian Museum of Nature.

We are facing a daunting task. The world will have to feed 10 billion mouths by 2050, but our current methods are unsustainable. Eleven percent of global emissions come from agriculture. Water, land and biodiversity are rapidly declining. And more than 800 million people continue to suffer from hunger.

One of the most exciting technological developments of today is AI. The applications of vertical AI—which is trained to deeply understand a single industry—are limitless. In my earlier career, I harnessed the power of AI for financial markets, then for cancer treatments. In my current work, I think a lot about how AI can help us tackle another complicated behemoth: the food system.

Unraveling the mystery of how catalytic organic polymers first appeared on prebiotic Earth will unlock key understandings in the origin of life.

Researchers from Tohoku University recently discovered a probable setting where the creation of catalytic organic polymers could occur. To make this discovery, they evaporated solutions of amino acids.

More than a quarter of all stroke victims develop a bizarre disorder—they lose conscious awareness of half of all that their eyes perceive.

After a stroke in the brain’s right half, for example, a person might eat only what’s on the right side of the plate because they’re unaware of the other half. The person may see only the right half of a photo and ignore a person on their left side.

Surprisingly, though, such stroke victims can emotionally react to the entire photo or scene. Their brains seem to be taking it all in, but these people are consciously aware of only half the world.
