For about a decade, the mainstream understanding has been that psychedelics cause chaos in the brain. Brain networks—the stable patterns of communication that handle vision, attention, or our sense of self, and more—loosen and start talking to each other all at once. EEG traces get noisier and more complex. “Think of the networks of the brain as highways,” says Devon Stoliker, a neuroscientist at Monash University. “Under psychedelics, these highways break down into many different directions.” In a recent Nature study, Stoliker’s team designed an experiment to test whether these directions are truly chaotic and random. Researchers gathered 62 people who had never taken a psychedelic before, gave them 19 milligrams of psilocybin, a common psychedelic found in certain fungi, and scanned their brains. Then, they used AI to analyze the drugged and sober brain scans. What emerged was not exactly chaos. An uninterrupted trip Stoliker thinks chaos is not a satisfactory explanation for psychedelics’ effect on the brain. “It never really explained why an individual would have a meaningful experience, why they might have insight, why they might experience clarity, and why these might translate into positive psychological changes,” Stoliker says. To investigate if there are other explanations, he and his colleagues designed a study called PsiConnect.Read full article Comments
The Stone Age owes its name to tools that survived to our time. The material early humans worked with most, though, was probably wood because it is so much easier to process. Unfortunately, we know very little about Paleolithic woodwork because wood rots relatively quickly. But at Abric Romaní, a rock shelter in Capellades, west of Barcelona, mineral-rich water coated wooden Neanderthal tools in a limestone-like crust. When wood rotted away, it left behind hollow molds that faithfully reflect its shape. In a recent Science Advances study, a team of Spanish archaeologists has cataloged 597 wooden remains from Neanderthal living areas dating from 62,000 to 40,000 years ago. They found spears, digging sticks, bark trays, parts of shelters, and a club unlike anything seen before, suggesting Neanderthals were likely much more than just Homo sapiens’ dumber cousins. Beyond hunting gear The oldest wooden artifacts we have are mostly weapons. They include spears from a German town called Schöningen, a spear tip from Clacton-on-Sea in England, and the spear found alongside an elephant skeleton in Lehringen, Germany. Most came from waterlogged sediments, where a lack of oxygen slowed decay.Read full article Comments
Ukrainian drone strikes have knocked out two of five data centers belonging to the Russian tech giant Yandex. The damage has left Yandex, known as “Russia’s Google” because it operates the country’s most popular search engine, struggling to maintain its AI chatbot and other online services. The Ukrainian drones struck Yandex data centers in the Sasovo and Kaluga regions of Russia on October 8 and October 9, according to Reuters. Those actions came as a direct response to a Russian drone strike campaign targeting Ukraine’s data centers, which has disrupted mobile phone and Internet services for thousands of Ukrainians since late September. “We continue to respond to Russia’s attacks on Ukraine, and we’re doing so with high precision,” said Ukrainian President Volodymyr Zelenskyy in a post on X. “Another data center was hit as well—our symmetrical response.”Read full article Comments
