Check out my interview with Dr. Noam Chomsky where he explains why we have more urgent problems than the technological singularity.
Universitätsklinikum Erlangen is the first in the world to use CAR T-cells to successfully treat a patient suffering from a severe case of muscle inflammation (myositis). The disease is triggered by a malfunction in the immune system that leads to inflammation of the muscles, and the risk of developing a very severe form of the disease is high. The Lancet has now published news of the successful treatment in a case report.
When the 41 year old Mr. S. noticed a dramatic deterioration in this health last year, he initially put it down to a viral infection. However, his health took a dramatic turn for the worse when he was suddenly no longer to move more than a few feet and was barely able to stand up. His symptoms were caused by a severe autoimmune disease affecting his muscles, joints, skin and lungs belonging to the group of anti-immune muscle inflammatory diseases (myositis). The diagnosis: anti-synthetase syndrome.
The name anti-synthetase syndrome is derived from the observation that the enzymes required for the synthesis of amino acids known as aminoacyl-tRNA synthetases are attacked in error by the immune system. This severely impacts the function of various cells.
Microsoft’s AI-powered Bing unnerved some people recently with shocking responses.
Amid discussions and scrutiny, OpenAI CEO Sam Altman shared his thoughts on AI In a series of tweets on Sunday.
He warned the world may not be “that far from potentially scary” AI and said regulation will be “critical.”
The study conducted by researchers at the University of British Columbia and the University of Victoria reveals that exposure to common levels of traffic pollution can impair brain function within hours.
The peer-reviewed study published in Environmental Health found that only two hours of exposure to diesel exhaust leads to a decrease in brain functional connectivity, which is a measure of how different areas of the brain interact and communicate with each other. This study is the first controlled experiment to provide evidence of air pollution altering brain connectivity in humans.
“For many decades, scientists thought the brain may be protected from the harmful effects of air pollution,” said senior study author Dr. Chris Carlsten, professor and head of respiratory medicine and the Canada Research Chair in occupational and environmental lung disease at UBC. “This study, which is the first of its kind in the world, provides fresh evidence supporting a connection between air pollution and cognition.”
A baby with a rare inherited disorder became the first child in the U.K. to receive a new gene therapy for the condition.
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.
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.
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?”
UK-based Hex wanted to visit friends in the U.S. but was barred from entering due to her virtual work.

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.
