Is buzzy startup Humane’s big idea a wearable camera?

The demo is clever, questionably real, and prompts a lot of questions about how this device will actually work.

Buzz has been building around the secretive tech startup Humane for over a year, and now the company is finally offering a look at what it’s been building. At TED last month, Humane co-founder Imran Chaudhri gave a demonstration of the AI-powered wearable the company is building as a replacement for smartphones. Bits of the video leaked online after the event, but the full video is now available to watch.

The device appears to be a small black puck that slips into your breast pocket, with a camera, projector, and speaker sticking out the top. Throughout the 13-minute presentation, Chaudhri walks through a handful of use cases for Humane’s gadget: * The device rings when Chaudhri receives a phone call. He holds his hand up, and the device projects the caller’s name along with icons to answer or ignore the call. He then has a brief conversation. (Around 1:48 in the video) * He presses and holds one finger on the device, then asks a question about where he can buy a gift. The device responds with the name of a shopping district. (Around 6:20) * He taps two fingers on the device, says a sentence, and the device translates the sentence into another language, stating it back using an AI-generated clone of his voice. (Around 6:55) * He presses and holds one finger on the device, says, “Catch me up,” and it reads out a summary of recent emails, calendar events, and messages. (At 9:45) * He holds a chocolate bar in front of the device, then presses and holds one finger on the device while asking, “Can I eat this?” The device recommends he does not because of a food allergy he has. He presses down one finger again and tells the device he’s ignoring its advice. (Around 10:55)

Chaudhri, who previously worked on design at Apple for more than two decades, pitched the device as a salve for a world covered in screens. “Some believe AR / VR glasses like these are the answer,” he said, an image of VR headsets behind him. He argued those devices — like smartphones — put “a further barrier between you and the world.”

Humane’s device, whatever it’s called, is designed to be more natural by eschewing the screen. The gadget operates on its own. “You don’t need a smartphone or any other device to pair with it,” he said.

This rechargeable battery is meant to be eaten

A team of researchers at the Italian Institute of Technology recently unveiled what is being billed as the world’s first fully rechargeable, edible battery. As detailed in a paper published with Advanced Materials, the new device utilizes riboflavin (often found in shiitake mushrooms) as its anode and quercetin (seen in capers) as the cathode. Activated charcoal amplified the electrical conductivity alongside a water-based electrolyte. Nori seaweed—most often seen in sushi—served as the short circuit prevention separator, while beeswax-encased electrodes and food-grade gold foil contacts also contributed to the design.

The battery relies on chemical components often found in shiitake mushrooms, capers, and seaweed—and may come in handy for children’s toys.

Genetic research sheds light on what the earliest animals looked like

For more than a century, biologists have wondered what the earliest animals were like when they first arose in the ancient oceans more than half a billion years ago.

Searching among today’s most primitive-looking animals for the earliest branch of the animal tree of life, scientists gradually narrowed the possibilities down to two groups: sponges, which spend their entire adult lives in one spot, filtering food from seawater; and comb jellies, voracious predators that oar their way through the world’s oceans in search of food.

In a new study published this week in the journal Nature, researchers use a novel approach based on chromosome structure to come up with a definitive answer: Comb jellies, or ctenophores (pronounced teen’-a-fores), were the first lineage to branch off from the animal tree. Sponges were next, followed by the diversification of all other animals, including the lineage leading to humans.

Mushrooms magnify memory

Researchers from The University of Queensland have discovered the active compound from an edible mushroom that boosts nerve growth and enhances memory.

Professor Frederic Meunier from the Queensland Brain Institute said the team had identified new active compounds from the mushroom, Hericium erinaceus.

“Extracts from these so-called ‘lion’s mane’ mushrooms have been used in traditional medicine in Asian countries for centuries, but we wanted to scientifically determine their potential effect on brain cells,” Professor Meunier said.

One of us! Engineers fool fish school into accepting robotic koi

One fish, swimming alone, encountering a robotic fish impersonator will be wary and tend to avoid the robot, but a group of real fish are more likely to accept the robot as one of their own, and sometimes even abandon other real fish to follow the robot.

Those are the findings of engineers from Peking University and China Agricultural University who created a realistic koi fish robot, and placed one or two in a tank with real fish to see how they would respond.

Digital DNA through your digital twin in the sentient-world-simulation

Perhaps your real life is so rich you don’t have time for another.

Even so, the US Department of Defense (DOD) may already be creating a copy of you in an alternate reality to see how long you can go without food or water, or how you will respond to televised propaganda.

The DOD is developing a parallel to Planet Earth, with billions of individual “nodes” to reflect every man, woman, and child this side of the dividing line between reality and AR.

Capsule captures first look inside digestion in healthy people

Using a specially designed capsule, researchers can now voyage through the digestive system, collecting new data about digestion and microorganisms. The work by a team including researchers at the University of California, Davis, Stanford University and Envivo Bio Inc., is published May 10 in papers in Nature and Nature Metabolism.

Most of the process of digestion takes place in our small intestine, where enzymes break down food so it can be absorbed through the gut wall.

“The small intestine has so far only been accessible in sedated people who have fasted, and that’s not very helpful,” said Professor Oliver Fiehn, director of the West Coast Metabolomics Center at UC Davis. Metabolomics is the study of the metabolome, the small molecules involved in metabolism in cells, tissues and organs. Fiehn is senior author on the Nature Metabolism paper and co-corresponding author on the Nature paper. Jacob Folz, a postdoctoral researcher at UC Davis, is first author on the Nature Metabolism paper.
