Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news

A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials。 Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much more safely during plasma processing。 The result is a cleaner, more controlled path toward smaller
Physicists have solved a long-standing problem involving systems that appear to violate Newton’s third law, such as bird flocks and bacterial swarms。 By adding carefully designed “imaginary partners” to their models, they can now simulate these complex systems with unprecedented accuracy
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō。 The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived
The Guardrails Alliance, which has raised $5 million, is positioning itself as a populist effort that will take on the pro-A。 interests trying to influence this year’s elections
Crypto Clipper spreads over USB and communicates over Tor
Stainless-steel pans may lack nonstick coatings, but they’re unfussy, they sear well, and they’re built for a lifetime of hard work
The Nex Playground will cost £269 (€319) when it is released on 22 June in the UK and Ireland
An AI company is sending free cleaners door-to-door in a bid to train the robots it hopes one day will replace them
Oxford physicists have created an entirely new type of Schrödinger’s cat-like quantum state using components that are themselves highly quantum in nature。 The advance could open new possibilities for more resilient quantum computers and deeper insights into the strange rules that govern the quantum universe
Researchers have created a new way to reconstruct the evolutionary history of complex plant genomes by analyzing genetic traces left by transposable elements。 The technique revealed that modern strawberries were assembled through multiple ancient genome-merging events, shedding new light on how major crop species evolved
Kevin Roose and Casey Newton explain why they try to include “a little chaos” when they record their New York Times tech podcast in front of a crowd in San Francisco
Researchers found that twisting layered sheets of hexagonal boron nitride can dramatically change the light produced by quantum emitters embedded within the material。 The technique offers an unexpected new level of control over components that could power future quantum computers, communications systems, and sensors
Why some argue the social media ban could have a profound affect on how young people gain new knowledge and the rest of us move around online
Artificial intelligence is expensive to use, many companies discovered。 That has led to a new era of saving costs
The Space Force wants to cut the time to field new satellites from years to weeks, days, or hours
A newly identified molecule called OLE helped restore the brain’s immune cells to a more protective state in Alzheimer’s models。 The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new therapeutic approach
Check before check-in。 What's behind a new safety campaign about power banks on aircraft
