An ancient ‘horizon calendar’ comes into view over Mexico City

An ancient ‘horizon calendar’ comes into view over Mexico City

The New York Times reports: Long before Europeans colonized North America, the Indigenous peoples in the valley where Mexico City would later arise may have followed a natural solar calendar that was so accurate it accounted for leap years. The “horizon calendar,” proposed in a new study, relied on natural landmarks in the valley’s rugged eastern mountains, and was kept in sync with the astronomical year by a temple atop a sacred volcano. The system may have been used by…

Nuclear fusion in lab finally makes more energy than it uses

Nuclear fusion in lab finally makes more energy than it uses

Science News reports: Scientists have finally managed to bottle the sun. Researchers with the National Ignition Facility in Livermore, Calif., have ignited controlled nuclear fusion that resulted in the net production of energy. The long-awaited achievement, to be announced December 13 by U.S. Department of Energy officials, is the first time a lab has been able to reproduce the reactions in the sun in a way that leads to more energy coming out of the experiment than going in. “This…

Society can’t slow climate change without reining in Big Tech, new report warns

Society can’t slow climate change without reining in Big Tech, new report warns

Inside Climate News reports: Any effort to curb global greenhouse gas emissions and stave off catastrophic warming is doomed to fail unless far more is done to address the “foundational” role Big Tech companies now play in exacerbating the climate crisis. That’s the conclusion of a new report released last week by the international environmental nonprofit Global Action Plan. From amplifying conspiracy theories and misinformation to their increasingly massive energy footprint, the world’s biggest tech companies aren’t only making global…

Apple makes plans to move production out of China

Apple makes plans to move production out of China

The Wall Street Journal reports: In recent weeks, Apple has accelerated plans to shift some of its production outside China, long the dominant country in the supply chain that built the world’s most valuable company, say people involved in the discussions. It is telling suppliers to plan more actively for assembling Apple products elsewhere in Asia, particularly India and Vietnam, they say, and looking to reduce dependence on Taiwanese assemblers led by Foxconn Technology Group. Turmoil at a place called…

A peek inside the FBI’s unprecedented January 6 geofence dragnet

A peek inside the FBI’s unprecedented January 6 geofence dragnet

Wired reports: The FBI’s biggest-ever investigation included the biggest-ever haul of phones from controversial geofence warrants, court records show. A filing in the case of one of the January 6 suspects, David Rhine, shows that Google initially identified 5,723 devices as being in or near the US Capitol during the riot. Only around 900 people have so far been charged with offenses relating to the siege. The filing suggests that dozens of phones that were in airplane mode during the…

Elon Musk’s Boring Company ghosts cities across America

Elon Musk’s Boring Company ghosts cities across America

The Wall Street Journal reports: The unsolicited proposal from Elon Musk’s tunnel-building venture arrived in January 2020. To the local transportation authority, it felt like finding Willy Wonka’s golden ticket. Officials had started planning for a street-level rail connection between booming Ontario International Airport and a commuter train station 4 miles away, with an estimated cost north of $1 billion. For just $45 million, Mr. Musk’s Boring Co. offered to instead build an underground tunnel through which travelers could zip…

Early humans may have cooked fish 780,000 years ago

Early humans may have cooked fish 780,000 years ago

Smithsonian magazine reports: Cooking with fire marked an important turning point in human evolution. But based on available evidence, determining exactly when early humans learned to cook is challenging. While researchers have discovered the remains of charred animals and root vegetables, that doesn’t necessarily mean people were grilling up steaks for dinner; they may have simply tossed a dead animal into the fire for disposal. Now, researchers in Israel say they’ve come up with a clever solution to this problem—and,…

Embrace what may be the most important green technology ever. It could save us all

Embrace what may be the most important green technology ever. It could save us all

George Monbiot writes: So what do we do now? After 27 summits and no effective action, it seems that the real purpose was to keep us talking. If governments were serious about preventing climate breakdown, there would have been no Cops 2-27. The major issues would have been resolved at Cop1, as the ozone depletion crisis was at a single summit in Montreal. Nothing can now be achieved without mass protest, whose aim, like that of protest movements before us,…

Climate inaction is making the desperate choice of solar geoengineering more likely

Climate inaction is making the desperate choice of solar geoengineering more likely

Bill McKibben writes: If we decide to “solar geoengineer” the Earth—to spray highly reflective particles of a material, such as sulfur, into the stratosphere in order to deflect sunlight and so cool the planet—it will be the second most expansive project that humans have ever undertaken. (The first, obviously, is the ongoing emission of carbon and other heat-trapping gases into the atmosphere.) The idea behind solar geoengineering is essentially to mimic what happens when volcanoes push particles into the atmosphere;…

This week, billionaires made a strong case for abolishing themselves

This week, billionaires made a strong case for abolishing themselves

Anand Giridharadas writes: In recent years, a swelling chorus of Americans has grown critical of the nation’s bajillionaires. But in the extraordinary week gone by, that chorus was drowned out by a far louder and more urgent case against them. It was made by the bajillionaires themselves. One after another, four of our best-known billionaires laid waste to the image of benevolent saviors carefully cultivated by their class. It is a commendable sacrifice on their part, because billionaires, remember, exist…

China’s high-tech surveillance drives oppression of Uyghurs

Steven Feldstein writes: On August 31, 2022, in the final hours of UN High Commissioner for Human Rights Michelle Bachelet’s term, after months of delays and postponements, her department released a comprehensive report detailing China’s oppression in Xinjiang Province. The circumstances of China’s repression are well documented. Academics and human rights organizations estimate that 10 to 20 percent (with an upper limit calculated at 1.8 million) of adult Uyghurs in Xinjiang have been subjected to detention by Chinese authorities. Officials…

The danger of advanced artificial intelligence controlling its own feedback

The danger of advanced artificial intelligence controlling its own feedback

DALL-E Michael K. Cohen, University of Oxford and Marcus Hutter, Australian National University How would an artificial intelligence (AI) decide what to do? One common approach in AI research is called “reinforcement learning”. Reinforcement learning gives the software a “reward” defined in some way, and lets the software figure out how to maximise the reward. This approach has produced some excellent results, such as building software agents that defeat humans at games like chess and Go, or creating new designs…
