Healthy fast food start up takes on the McDonald’s empire

Posted by in categories: business, food

In an attempt to radically alter the fast food industry, one Los Angeles based business is serving up healthy fast food at the same low cost as competitors like McDonald’s and Burger King.

The people at Everytable believe that healthy food isn’t a luxury product to be enjoyed by the most affluent, but rather, it is a human right that should be accessible to all. So they came up with a unique business model that enables them to provide cheap healthy food in low-income communities and food deserts.

Human brain cells in a dish learn to play Pong faster than an AI

Posted by in category: robotics/AI

Hundreds of thousands of brain cells in a dish are being taught to play Pong by responding to pulses of electricity – and can improve their performance more quickly than an AI can.

‘It became me’: Studies show that revolutionary new brain chips may bend your mind in strange and troubling ways

Posted by in categories: biotech/medical, computing, cyborgs, neuroscience

Musk’s company is far from the only group working on brain-computer interfaces, or systems to facilitate direct communication between human brains and external computers. Other researchers have been looking into using BCIs to restore lost senses and control prosthetic limbs, among other applications. While these technologies are still in their infancy, they’ve been around long enough for researchers to increasingly get a sense of how neural implants interact with our minds. As Anna Wexler, an assistant professor of philosophy in the Department of Medical Ethics and Health Policy at the University of Pennsylvania, put it: “Of course it causes changes. The question is what kinds of changes does it cause, and how much do those changes matter?”

The brains of reptiles seemed to offer a clue. Not only are reptiles the closest living relatives of mammals, but their brains have a three-layered structure called a dorsal ventricular ridge, or DVR, with functional similarities to the neocortex.

The neocortex stands out as a stunning achievement of biological evolution. All mammals have this swath of tissue covering their brain, and the six layers of densely packed neurons within it handle the sophisticated computations and associations that produce cognitive prowess. Since no animals other than mammals have a neocortex, scientists have wondered how such a complex brain region evolved.

Scientists regenerate kidneys to reverse diabetes damage in mice

Posted by in category: biotech/medical

An international team of scientists has found a way to regenerate kidneys damaged by disease, restoring function and preventing kidney failure. The discovery could drastically improve treatments for complications stemming from diabetes and other diseases.

Diabetes causes many problems in the body, but one of the most prevalent is kidney disease. Extended periods of elevated blood sugar can damage nephrons, the tiny filtering units in the kidneys, which can lead to kidney dysfunction and eventually failure.

Mark Zuckerberg demos a tool for building virtual worlds using voice commands

Posted by in category: robotics/AI

Meta, formerly known as Facebook, today showed off a prototype of an AI system that enables people to generate or import things into a virtual world just by using voice commands. The company sees the tool, which is called “Builder Bot,” as an “exploratory concept” that shows AI’s potential for creating new worlds in the metaverse. Meta CEO Mark Zuckerberg showed off the prototype at the Meta AI: Inside the Lab event on Wednesday in a pre-recorded demo video.

In the video, Zuckerberg explained the process of building parts of a virtual world by describing them. He begins with the prompt, “let’s go to a park.” The bot then creates a 3D landscape of a park with green grass and trees. Zuckerberg then says “actually, let’s go to the beach,” after which the bot replaces the current landscape with a new one of sand and water. He then says he wants to add clouds and notes that everything is AI-generated. Zuckerberg then changes up the landscape by saying he’d rather have altocumulus clouds, which is meant to demonstrate how specific the voice commands can be.

Researchers develop new method for specializing and purifying human stem cells into interneurons

Posted by in categories: biotech/medical, life extension, neuroscience

Injury to the spinal cord often leads life changing disability, with decreased or complete loss of sensation and movement below the site of injury. From drugs to transplantation, there are many scientific advances aiming to restore function following spinal cord injury.

One promising approach is the use of stem cell derived neurons to replace those damaged. New research from the Centre for Gene Therapy & Regenerative Medicine and Centre for Neurodevelopment at King’s College London hopes to improve on this approach by providing pure populations of neurons made from stem cells.

The spinal cord is a delicate structure, with neurons carry messages from your brain to the rest of your body to allow movement and sensation. Integral to this system are interneurons, or the cells that relay information between your brain and other neurons. Research has previously shown that transplanting a class of interneurons, ventral spinal interneurons, to treat spinal cord injury in animal models provides promising recovery of sensory and motor function.

Transplanting a Gene Common in Centenarians Could Rewind The Heart’s Age

Posted by in categories: biotech/medical, life extension

Age catches up with us all eventually, but in some people the right genes can make that chase into our twilight years a relatively leisurely one.

A few years ago Italian researchers discovered something special about people who live well into their 90s and beyond: they commonly have a version of a gene called BPIFB4 that protects against cardiovascular damage and keeps the heart in good shape for a longer period of time.

By introducing the mutated gene into older mice, the scientists have now seen how the variant rewinds markers of biological heart aging by the equivalent of more than 10 human years.

Physicists want to use gravitational waves to ‘see’ the beginning of time

Posted by in category: physics

Gravitational waves are ripples in the fabric of space. Waves that originated in the early universe could carry important information about the phenomena that occurred there.
