Users of a naturally occurring psychedelic drug are convinced they've encountered real alien beings, including'machine elves,' which inhabit a realm beyond our Earth. These machine elves, described as chattering, mischievous entities, consistently appear in the visions of those who take DMT, which one neuroscientist suggested could mean users are actually entering a shared alien reality. DMT (or N,N-Dimethyltryptamine) is present in thousands of plants, including ayahuasca, which is used in religious ceremonies, but is also present in small amounts within the human body. Dr Andrew Gallimore, who has a PhD was in biological chemistry and has studied computational neuroscience, said he encountered these beings firsthand after being transported to a hyper-dimensional world teeming with intelligent lifeforms. Unlike earthly creatures, these beings - ranging from insectoids to God-like figures -seem to exist in a space that defies our three-dimensional understanding.

Scientists have discovered what really separates a cold-blooded psychopath from the average person. A team from the University of Pennsylvania has uncovered stark differences in brain structure that may explain why psychopaths think, feel, and behave in profoundly disturbing ways. Using MRI scans, researchers compared the brains of 39 adult men with high psychopathy scores to those of a control group, and what they found was unsettling. In psychopaths, researchers found shrunken areas in the basal ganglia, which controls movement and learning, the thalamus, the body's sensory relay station, and the cerebellum, which helps coordinate motor function. But the most striking changes were found in the orbitofrontal cortex and insular regions, areas that govern emotional regulation, impulse control, and social behavior.

Financial services firms are making early gains from artificial intelligence (AI), which is not surprising given that finance is historically an industry that embraces new technologies aggressively. One surprising outcome is that AI might end up making the most critical functions of banking, insurance, and trading, or the creative functions that require human insights, even more valuable. "What happens is there's going to be a premium on creativity and judgment that goes into the process," said John Kain, who is head of market development efforts in financial services for AWS, in an interview with ZDNET via Zoom. By process, he meant those areas that are most advanced, and presumably hardest to automate, such as a bank's risk calculations. "So much of what's undifferentiated will be automated," said Kaine.

The original version of this story appeared in Quanta Magazine. When Todd Sacktor was about to turn 3, his 4-year-old sister died of leukemia. A swing set with two seats instead of one," he said, recalling the lingering traces of her presence in the house. "There was this missing person--never spoken of--for which I had only one memory." That memory, faint but enduring, was set in the downstairs den of their home.

Whether or not we grow new brain cells as adults has been the subject of an ongoing and often contentious debate. Now, evidence suggests that we can. This could help answer one of neuroscience's most controversial questions and has sparked some speculation that the process could be exploited to treat conditions like depression and Alzheimer's disease. New neurons form via a process called neurogenesis in children, as well as in adult mice and macaques. This involves stem cells repeatedly giving rise to so-called progenitor cells that proliferate to form immature neurons that later become fully developed. Prior studies on human adults have identified stem cells and immature neurons in the hippocampus.

When someone loses the ability to speak because of a neurological condition like ALS, the impact goes far beyond words. Now, thanks to a team at the University of California, Davis, there's a new brain-computer interface (BCI) system that's opening up real-time, natural conversation for people who can't speak. Instead, it translates the brain signals that would normally control the muscles used for speech, allowing users to "talk" and even "sing" through a computer, almost instantly.

By 2030, rapid technological advancements are expected to reshape humanity, unlocking abilities once confined to science fiction--from superhuman strength to enhanced senses. Robotic exoskeletons may soon allow people to lift heavy objects with ease, while AI-powered wearables, such as smart glasses and earbuds, could provide real-time information and immersive augmented reality experiences. Healthcare may be revolutionized by microscopic nanobots capable of repairing tissue and fighting disease from within the bloodstream, potentially extending human lifespans. Developers are also working on contact lenses with infrared vision and devices that allow users to "feel" digital objects, paving the way for entirely new ways to experience the world. Tech pioneers like former Google engineer Ray Kurzweil believe these innovations are early steps toward the merging of humans and machines, with brain-computer interfaces offering direct access to digital intelligence.

Paradromics is shifting from research to clinical trials. Recently, a neurotech company called Paradromics made headlines by successfully implanting its brain-computer interface (BCI) in a human for the first time. The procedure happened at the University of Michigan during a patient's routine epilepsy surgery. The device was both placed and removed in just about 20 minutes, a quick turnaround for such a complex technology. This achievement is a big deal for Paradromics, which has been working on this brain implant technology for nearly 10 years.

Tens of millions of Americans engage in a taboo habit that scientists have warned could pose risks to cognitive health. A recent study found that regularly viewing pornography can immediately reduce a person's performance on tasks requiring attention and cognitive control right after exposure to explicit content. Impaired executive function and reduced cognitive performance are known early markers of cognitive decline, a precursor to dementia. Research has suggested that if such effects are sustained or repeated over time, they could potentially contribute to long-term health risks. In the study, college students watched a 10-minute internet pornographic video chosen for its high viewership.

Apple just said, "Allllllll y'all reasoning models are full of…" Fine, it didn't actually say that. That was my loose interpretation of Apple's recently published report, "The Illusion of Thinking." Also: Is ChatGPT Plus really worth 20 when the free version offers so many premium features? If you aren't familiar, Apple just confirmed what many suspected for the longest: there's no "thinking" happening in Large Reasoning Models (LRM); it's all advanced pattern matching. This report brings up soooooooo many questions.
