A new study put ChatGPT to the test by asking it to judge whether hundreds of scientific hypotheses were true or false—and the results were far from reassuring. While the AI got it right about 80% of the time on the surface, its performance dropped significantly when accounting for random guessing, revealing only modest reasoning ability. Even more concerning, it frequently contradicted itself when asked the exact same question multiple times, sometimes flipping answers back and forth.

Привет, меня зовут Константин, я бэкенд-разработчик. В свободное от работы время я разрабатываю продукты в компании Elevo. При создании новых сервисов важно правильно спроектировать архитектуру базы данных. В некоторых проектах это десятки таблиц, несколько схем, связи между ними и замоканные данные. Всё это важно держать в голове до мелочей, чтобы в какой-то момент не сломать логику всего продукта.При постоянном переключении между проектами или долгого перерыва некоторые детали забываются, меняются, устаре Read more ›

An anonymous reader quotes a report from 404 Media, written by Jason Koebler: Over the last few months, various academics and AI companies have attempted to predict how artificial intelligence is going to impact the labor market. These studies, including a high-profile paper published by Anthropic earlier this month, largely try to take the things AI is good at, or could be good at, and match them to existing job...

THC doesn’t just blur memories—it can create new ones that never happened. In a controlled experiment, cannabis users were much more likely to recall words that were never shown and struggled with tasks like remembering to do something later. Researchers found that THC disrupted many different memory systems at once. Surprisingly, moderate doses caused memory problems similar to higher doses. Read more ›

A long-running debate about the Silverpit Crater beneath the North Sea has finally been resolved. Scientists now confirm it formed when a roughly 160-meter asteroid struck the seabed about 43–46 million years ago. New seismic imaging and rare shocked minerals in rock samples provided the crucial proof. The impact would have sent a massive plume skyward and unleashed a tsunami over 100 meters (330 feet) high.

As deep-sea waters warm, scientists expected trouble for the microbes that help keep ocean chemistry in balance. Instead, researchers found that Nitrosopumilus maritimus can adapt to warmer, iron-limited conditions by using iron more efficiently. Because these microbes control key nitrogen reactions that support marine life, their adaptability could help sustain ocean productivity. In a warming world, they may play an even bigger role in shaping marine nutrient cycles. Read more ›

Researchers have uncovered a molecular trick used by hornwort plants that could help future crops capture carbon dioxide more efficiently. A unique protein feature called RbcS-STAR causes the key photosynthesis enzyme Rubisco to cluster into dense compartments, helping it work more effectively. When scientists added this feature to other plants, Rubisco reorganized in the same way. The finding raises the possibility of engineering more efficient photosynthesis into major crops. Read more ›

A European clinical trial found that the drug sulthiame significantly reduced breathing interruptions in people with moderate to severe sleep apnea. Patients taking higher doses experienced up to 47% fewer pauses in breathing and improved oxygen levels during sleep. The drug helps stabilize breathing signals in the brain, reducing airway collapse. Scientists say the findings could pave the way for a pill-based alternative to CPAP machines. Read more ›

Scientists have developed a promising new approach to treating Alzheimer’s disease by turning ordinary brain cells into powerful plaque-clearing machines. Instead of requiring frequent antibody infusions like current therapies, the experimental treatment uses genetically engineered astrocytes — abundant support cells in the brain — that are equipped with a CAR “homing device” similar to those used in cancer immunotherapy.

Coenzyme A, a molecule derived from vitamin B5, is vital for metabolism throughout the body. Scientists discovered that most of it resides inside mitochondria, yet how it reached these cellular powerhouses was unclear. Yale researchers have now identified the transport system that moves CoA into mitochondria, solving a long-standing biological puzzle. The discovery could help researchers better understand diseases linked to metabolic dysfunction and mitochondrial problems. Read more ›

Teenagers naturally fall asleep later, which makes early school start times a recipe for chronic sleep deprivation. Researchers studying a Swiss high school that introduced flexible start times found that students overwhelmingly chose to begin later—and ended up sleeping about 45 minutes longer each school night. The extra rest led to fewer sleep problems, better well-being, and improved academic performance. Read more ›

A newly developed antibiotic called EVG7 could offer a powerful new way to stop Clostridioides difficile, a dangerous gut bacterium that often returns after treatment. In mouse studies, researchers found that even a very small dose of EVG7 was highly effective at clearing the infection and preventing it from coming back. Unlike many current antibiotics, which wipe out large portions of the gut microbiome, EVG7 appears to spare beneficial bacteria... Read more ›

Researchers exploring Uganda’s Kibale National Park have discovered seven new species of frog-like leafhoppers. The tiny insects, named for their frog-shaped bodies and powerful jumping legs, are so similar in appearance that scientists must examine microscopic anatomical details to tell them apart. The find represents the first new African species of this group recorded since 1981. One species was named in honor of the scientist’s late mother. Read more ›
