What defines humanity? Is it the fact that we can walk upright on two legs? That we have brains big enough to use tools? That we can organize our societies well enough to find wonderful ways of exploiting the resources of the planet — and each other?While the answer may seem clear enough to anyone who doesn’t think too closely about it, anthropologists — the scientists who actually study humans — aren’t necessarily so certain.“We’re using this term and it’s not quite colloquial a ...read more

On July 2, 1937, pilot Amelia Earhart and navigator Fred Noonan hopped into their Lockheed 10-E Electra and headed for Howland Island, a 0.6-square-mile coral atoll in the middle of the Pacific Ocean. Following takeoff, the pilot, the navigator, and the plane were never seen again.The two disappeared during their attempt to fly their way around the world, with the location of their disappearance having eluded experts for decades. But this week, experts from the ocean exploration firm Deep Sea V ...read more

If you can sense changes in the weather based on aches and pains in your body, you aren’t alone. Many people, especially older individuals with arthritis, claim that they can feel the weather based on the pain in their joints. While research hasn’t nailed down these weather-related pain claims, anecdotal evidence persists. How the Weather Impacts Your JointsIt’s probably why so many people want to retire where it’s warm, says Aly Cohen, a rheumatologist in Princeton, New Jersey. Cold we ...read more

Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can quickly turn chilly and dangerous for people and pups alike.Winter brings some unique challenges fo ...read more

What makes us human? Many answers would suffice, but in particular, our names offer an overlooked perspective on our humanity. Perhaps this is because names fall on somewhat of a nebulous side of our identity. Names aren’t etched onto our DNA, and technically, they can be abandoned or customized at the whim of their owners. But for most, a name clings until the end of life and exists beyond death. To understand how we distinguish one another with names, you would need to sift through unfathoma ...read more

It was 1910, or maybe 1911 or 1912, when Wilfrid Voynich, a Polish-born antiquarian, purchased a strange, medieval manuscript.Similar in size to an average paperback, at around 6 inches by 9 inches, the book burst at the seams, brimming with words and pictures of peculiar plants, strange stars, and bathing female figures. At around 232 pages, the book bore no indication of its authors and lacked the luster — and the metal leaf — seen in many manuscripts from the “illuminated” age. Increa ...read more

When high-quality images produced by generative AI first began to appear in 2022, they had an undeniable wow factor. The creative process involved little more than entering a text description and waiting for the AI system to produce a relevant image. At that time, an obvious question was when AI-generated video would catch up. Indeed, various groups have since unveiled AI systems that automatically generate video, but always with important limits to their length, the type of realistic motion the ...read more

The relationship between humans and Neanderthals has consistently been shrouded in mystery, but a collection of new studies has now solved a major piece of the puzzle. Based on analysis of ancient bone fragments, researchers shed light on early humans’ presence in northern Europe alongside Neanderthals, answering questions that have long engulfed the science community. Researchers set their sights on Ilsenhöhle, an archaeological site at the base of a castle in Ranis, Germany. An internation ...read more

Living in a city is different from our how our ancestors lived, who were in a more nature-filled environment. Only 3 percent of the world’s population lived in cities back in 1800, compared to over 50 percent today. As researchers of a 2019 study published in the Yale Journal of Biology and Medicine state, our attention system was “designed for interacting with nature.”There’s no doubt there are pros and cons to city living. You step outside, and you’re closer to shops and entertainmen ...read more

The continent-spanning nature of the United States means that we have a lot of different geologic conditions. The eastern half of the country is in the (mostly) stable part of the North American plate while the western half (including Alaska) is in the much more dynamic part of the plate. However, that doesn't mean that the earthquake hazards that our cities face is only a worry for someone living in California.The latest model of potential earthquake shaking hazard for the country was recently ...read more
