At first glance, the fossil itself appears unimpressive. It looks like a dark, cylindrical stone with a dull, cracked surface that has been there for a long time, sitting behind glass in a softly lit museum collection in Scotland. Instead, they are drawn to dinosaurs or early fish with distinguishable eyes and teeth, so visitors pass it without pausing. There is a subtle tension surrounding this object, though, as scientists now think it may be a remnant of a long-extinct branch of life. It’s difficult to ignore how unnerving that thought is. More than 400 million years ago, the organism…

Last spring, on a warm evening in southern California, valet attendants in black suits waited outside a vineyard with crystal glasses reflecting the setting sun and white roses climbing wooden archways. Arriving in opulent SUVs, guests paused to look at the seating chart printed on thick handmade paper while adjusting their tailored jackets and silk dresses. There was a whisper, almost casual, that the wedding had cost more than $100,000. Nobody seemed shocked. Now, that’s what feels different. Not the figure per se, but the response to it. Ten years ago, weddings costing six figures were so uncommon that they…

Earlier this year, that familiar mix of scientific oversimplification and political optimism permeated the air in a packed Tennessee auditorium. Standing under bright stage lights, Robert F. Kennedy Jr. spoke confidently about mental health and nutrition, implying that schizophrenia could be cured by the ketogenic diet, which is well-known for reducing carbohydrates and increasing fat intake. While some audience members clapped, others nodded. Confusion and hope might have been nearly identical at that precise moment. Psychiatrists responded immediately and uneasily. Doctors who have dedicated their lives to treating schizophrenia heard something that sounded more like risk than innovation in hospital…

On a southern Spanish July afternoon, Seville’s pavement gleams like glass. While locals move swiftly, heads down, as if crossing an invisible hazard, tourists congregate under narrow strips of shade, pressing water bottles against their foreheads. Heat doesn’t simply linger in the atmosphere. It demands attention by pressing. Scenes like this, which were formerly regarded as extreme, might be subtly becoming commonplace. Heatwaves like these are becoming more frequent and lasting longer than anyone could have reasonably predicted, according to a United Nations climate panel. According to their most recent estimate, almost everyone on the planet may be exposed to…

Observing the gray Atlantic heave and fold beneath low clouds while standing on a windswept beach in western Ireland makes it difficult to imagine that something delicate is beneath that agitated surface. Even the waves appear to be eternal and powerful. The ocean’s most vital circulation system, however, is deteriorating, according to scientists, and the change is so subtle that most people will never notice it. At its most basic, the Atlantic Meridional Overturning Circulation is a planetary conveyor belt, even the name itself sounds heavy and mechanical. Warm water from the tropics moves northward, passing Florida and heading for…

The first thing that one should realize about Antarctica is how peaceful it is. Even in satellite photos, it appears to be frozen in time, encased in a sea of white and light blue, with clouds slowly floating overhead like partially formed thoughts. However, something is stirring once more far above that quiet continent; according to scientists, this hasn’t happened quite like this since the beginning of modern temperature records in the middle of the 19th century. Temperatures have risen sharply high in the stratosphere, about 30 kilometers above the ice. The temperature of air, which is typically around minus…

Houston’s sidewalks are deserted by mid-afternoon in an unfamiliar way. Even though cars are still moving and their engines are humming, people are hiding indoors from a sun that feels more like a threat than a weather pattern. Something feels different now, even in Texas, where heat has always been a part of the culture. It’s not just that the summers are hotter. They are heavier, stay longer, and press down with a tenacity that makes residents uncomfortable and hospitals busier. Public health officials were subtly shocked to learn that 334 people in Texas lost their lives to heat-related causes…

Outside of Lyon, the road to the research campus feels almost purposefully unremarkable, with modest office buildings and logistics warehouses hidden behind metal fencing. Yet, behind those subdued exteriors, France is putting together something much more ambitious than it first seems: the National Quantum Computing Center, a project that was conceived out of President Emmanuel Macron’s €1.8 billion wager that the nature of computing is about to change. It seems as though Lyon was picked out of instinct rather than chance. The city, which has always been more focused, less theatrical, and industrious, has always existed in the shadow of…

With its propellers slicing through the humid morning air, the drone slowly rose from the edge of a concrete landing pad close to India’s western coastline. Fishermen nearby stopped for a moment as they watched the machine raise a tiny white container, which was said to contain diagnostic samples that would typically take hours to transport by road. Perhaps something more significant than a standard logistics test was caught in that instant. It seemed like a subtle change in the direction of healthcare. India and the United Arab Emirates have started collaborating on the delivery of medical supplies via coastal…

Pinghu City’s greenhouse doesn’t smell like a farm. It has a fresh scent. The typical mixture of moist soil and fertilizer is barely perceptible, replaced by the sterile silence of silent machinery. Tiny sensors that measure everything from temperature to moisture are arranged in tidy rows next to leafy greens and blink dimly. As you watch them, you get the impression that farming has changed from being something that is done with the hands to something that is done with numbers. IoT-powered smart farming has started to spread throughout Zhejiang Province’s agricultural areas, and the shift is more disturbing than…
