Crabs’ famous sideways walk may trace back to a single evolutionary moment 200 million years ago. Researchers found that most modern crabs inherited this trait from one ancestor—and never looked back. The movement likely gave them an edge, helping them dodge predators with quick, unpredictable bursts. It’s a rare example of a behavior evolving once and then dominating an entire group.

Когда вы пишете loss.backward() в PyTorch, ваш autograd делает то, что 200 лет считалось математической ересью: оперирует бесконечно малыми как настоящими числами.В 1960 году Абрахам Робинсон формализовал эту «ересь» в виде нестандартного анализа.В этой статье мы разберём, как математики изгнали, а затем вернули бесконечно малые, что такое гиперреалы и монады, а затем реализуем эту идею в коде.

The once-a-year free comic book giveaway "is splitting in two," according to a local news report. Launched in 2002 by Diamond Comic Distributor, comic book giants like Marvel and DC have historically participated together. But things changed after Diamond Comic Distributors went bankrupt in 2025, "leaving other companies to swoop in and pick up where Diamond left off." The rights to the "Free Comic Book Day" brand were sold to... Read more ›

A French retailer is willing to sell you defective RTX 5090s for half of what they cost new, on the condition that you'll be able to repair or recycle them. You can either get a random 5090 variant, depending on stock, for around $1,760 or pay almost $2,000 specifically for an MSI Ventus 3X OC model. The units come with transport-related damage.

Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a surprisingly simple setup based on liquid crystals. Instead of relying on complex nanotechnology, the team used self-organizing structures called torons to trap and manipulate light, causing it to spiral and rotate in intricate ways. Even more impressively, they achieved this effect in light’s most stable, lowest-energy state, making it far easier... Read more ›

A gut bacterium may be quietly fueling depression through an unexpected chemical twist. Researchers found that when Morganella morganii interacts with a common pollutant, it produces a molecule that triggers inflammation—something strongly linked to depression. This finding helps explain how gut microbes can influence brain health at a molecular level. It also raises the possibility of new treatments that target the immune system rather than just the brain.

Beneath East Africa’s Turkana Rift, scientists have found the crust is thinning to a critical point, suggesting the continent is gradually breaking apart. This “necking” process marks an advanced stage of rifting that could eventually lead to a new ocean forming millions of years from now. Surprisingly, the same geological forces that are splitting the land may also explain why the region holds such a rich fossil record. Instead of... Read more ›

For ages, wall lizards coexisted in three distinct color types, each with its own strategy for survival. Now, a powerful green variant is taking over. These dominant “Hulk” lizards are outcompeting the others, causing yellow and orange morphs to vanish. It’s a dramatic reminder that evolution can flip the script much faster than expected.

As Alaska’s rivers warm, invasive northern pike are becoming noticeably more voracious. Scientists discovered that pike of all ages are eating more fish, with young pike increasing consumption by over 60%. Warmer water speeds up their metabolism, pushing them to hunt more. This growing appetite could spell trouble for struggling salmon populations. Read more ›

Scientists have uncovered how graphene oxide pulls off a remarkable trick: it hunts down and destroys harmful bacteria while leaving human cells completely unharmed. By targeting a molecule found only in bacterial membranes, this ultra-thin carbon-based material acts with laser-like precision—offering a powerful new alternative to traditional antibiotics. Even more exciting, it works against drug-resistant “superbugs,” promotes faster wound healing, and keeps its antibacterial strength even after repeated w Read more ›

Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated. Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually interfere with the brain’s ability to repair itself. Instead of helping recovery, it appears to weaken blood vessel stability, disrupt healing signals, and even contribute to harmful protein buildup linked to cognitive decline. Read more ›

Scientists have uncovered a surprising new picture of human origins that challenges the long-held idea of a single ancestral population in Africa. By analyzing genetic data from diverse modern African groups—especially the highly distinct Nama people—and comparing it with fossil evidence, researchers found that early humans likely evolved from multiple intermingling populations over hundreds of thousands of years. Rather than a clean split, these groups stayed connected, exchanging genes even... Read more ›

Dinosaur DNA may still be out of reach, but scientists are uncovering something almost as exciting—ancient blood vessels hidden inside fossilized bones. In a massive Tyrannosaurus rex nicknamed Scotty, researchers discovered a network of preserved vessels within a rib that once fractured and began healing 66 million years ago. Using powerful synchrotron X-rays from particle accelerators, they were able to peer inside the dense fossil without damaging it, revealing intricate,... Read more ›

The famous mezcal “worm” has long puzzled scientists, but DNA testing has finally cracked the case. Researchers found that all sampled larvae were actually agave redworm moth caterpillars—not a mix of species as once believed. While the discovery clears up a long-standing mystery, it also raises concerns about sustainability. Growing demand for mezcal and edible larvae could put pressure on wild populations and the agave plants they depend on. Read more ›
