AI’s true impact will become apparent in the coming year Will it be boom, bust or backlash? In 2026 expect the economic, financial and social consequences of AI to grab attention

The hype and the hopes around AI have been like nothing the world has seen before, and the true nature of its impact is still unclear.

These are our predicted ramifications of the tech in the year ahead

‘It’s a Mess’: A Brain-Bending Trip to Quantum Theory’s 100th Birthday Party | Quanta Magazine Hundreds of physicists (and a few journalists) journeyed to Helgoland, the birthplace of quantum mechanics, and grappled with what they have and haven’t learned about reality.

An enjoyable article by Charlie Wood for Quanta magazine, portraying some of the views in the Helgoland conference. Thanks for the careful work! Very important and necessary.

Two views of planet Mars on a black background of space observed by the Hubble Space Telescope. At left, text: December 28, 2024 20:00 UT. At right, text: December 29, 2024 13:18 UT. In both images, its atmosphere is clear and the surface appears detailed. Most of the planet is shades of orange. At left, the brightest orange area appears in the left half. At right, the brightest orange area is centered and takes on the rough shape of a sleeping mask. In both views, darker surface features are noticeable on the lower half of the planet. These have a mix of orange, blue, and gray hues. At the top and bottom, white regions mark the planet’s polar caps. The entire limb of the planet, its visible edge, has a blue hue. The blue doesn’t form an even circle at the edges, and appears thinner toward the left and right, and thicker in some areas.

The planetary nebula NGC 2899 is shaped like a single macaroni noodle, with its edges pointed up, but its edge-on central torus is semi-transparent in the middle. The top and bottom edges are thick and orange. The center is semi-transparent blue and green. The wider central region looks roughly like a moth, also filled with semi-transparent blue and green. There are two pinpoint-like white stars with diffraction spikes toward the center. Immediately below them, slightly toward the right, is a smaller blue orb, a central star. The next layer of gas and dust is whiter, with some thicker pillars that look like they are rising up at bottom center. The colour fades into reds and purples, and then to orange.

A tiny portion of the Rosette Nebula. Very dark gray material shaped like a V extends from just below top left all the way down to the lower right corner and back up toward the top right. It looks like thick smoke that has billowed out irregularly, thicker along the line from top left to bottom right, and looser on the piece that goes toward the top right. Behind the dark gray on the left side, from the bottom left to top center, there is dust that looks like arced claw marks that appears in light orange and yellow. The background at top left is hazier and some blues are covered in semi-transparent orange wisps, which makes sections take on green hues. In the bottom right, the background is bluer. There are a few bright red and purple stars scattered along the right half, most toward the bottom. The largest star is at right-center, just at the edge. It is red and has four diffraction spikes.

Barred spiral galaxy NGC 5335 observed by the Hubble Space Telescope takes up the majority of the view. At its center is a milky yellow, flattened oval that extends bottom left to top. Within the oval is a bright central region that looks circular, with the very center the brightest. In the bright central region is what looks like a bar, extending from top left to bottom right. Around this is a thick swath of blue stars speckled with white regions. Multiple arms wrap up and around in a counterclockwise direction, becoming fainter the farther out they are. Both the white core and the spiral arms are intertwined with dark streaks of dust. The background of space is black. Thousands of distant galaxies in an array of colors are speckled throughout.

Happy anniversary, Hubble! 🎂

Celebrate 35 years since this NASA/ESA space telescope was launched into orbit with four anniversary images! They roam from the planet Mars to dramatic images of stellar birth and death to a neighbouring galaxy.

Quantum Mechanics in Zurich Zurich has a prominent place in the history of quantum science. We profile a few of the protagonists who shaped the field over the past century — with many more stories yet to be told.

Today, April 14, is #WorldQuantumDay and 2025 is the International Year of Quantum Science and Technology. A good opportunity to look at the history of quantum science in Zurich and get to know some of the most prominent protagonists: qc.ethz.ch/the-center/q...

Opinion: Emerging markets are often characterised by uncertain economics, corrupt politics, institutions that are too weak to enforce democratic norms, violence and social polarisation. The US has been heading in that direction since 2016 www.ft.com/content/e7a0...

A line graph shows the time series of global mean surface temperature anomalies for each March from 1850 through 2025. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly in March 2025 was 1.31°C globally. Anomalies are computed relative to a 1901-2000 climate baseline. A map of temperature anomalies in March 2025 is also shown. Red shading is for warmer than average temperatures, and blue shading is shown for colder than average temperatures. The climatological baseline on the map is relative to 1971 to 2000. All data is from NOAA/NESDIS/NCEI NOAAGlobalTemp v6.0.0 on this graphic.

In the NOAAGlobalTemp v6 dataset, last month was the 3rd warmest March on record. Small differences in rankings between datasets can occur. Particularly extensive warm anomalies were observed over Europe ⚒️🧪
