This week, a team of over 1,000 scientists from around the globe released to the public the first batch of data collected with the Dark Energy Spectroscopy Instrument (DESI), a telescope that cosmologists hope will help answer open questions on the nature of dark energy and the evolution of the Universe [1– 3]. “The telescope works better than we ever imagined,” says Michael Levi, a cosmologist at Lawrence Berkeley National Laboratory (LBNL), California, and the director of the DESI Collaboration. “We are ready to have everybody look at this [initial] data release and see what they can do with it.”
The goal of the five-year-long DESI survey is to map the Universe deeper in time and higher in detail than any previous telescope (see Feature: Entering a New Era of Dark Energy Cosmology). “We want to go way beyond what was done before and really be able to see the evolution of dark energy over the history of the Universe,” says Nathalie Palanque-Delabrouille, a cosmologist at LBNL and one of the spokespeople for the DESI Collaboration. To see that evolution, the survey plans to pinpoint the locations of over 40 million galaxies. The key to filling in the cosmic map is the use of robotic technology that automatically alters the placements of light-collecting fibers so that they can retrieve spectroscopic information from targeted bright spots in the sky. The spectral measurements provide information on what an object is and how fast it is moving away from us, which is needed to estimate its distance.
The robotic technology used to target objects had never been tried before, so it was not always clear that DESI would perform as expected, Levi says. But he and other team members have been pleasantly surprised by how smoothly the machine has operated. “DESI has preserved every photon that the Universe gave us,” he says.
Using AI-generated duplicates, brands also benefit, using stars in ways they never could before.

This week my guest Anne Scherer, a professor of marketing at the University of Zurich who specializes in the psychological and societal impacts that result from the increased automation and digitization of the consumer-company relationship.
In this episode we focus on the details Anne covers in, You and AI, a book she co-authored with Cindry Candrian to bring an accessible understanding of the ways in which AI is shaping our lives. This takes on a tour of topics such as our symbiotic relationship with AI, manipulation, regulation, the proposed 6 month pause on AI development, the business advantages of better data policies around AI, the difference between artificial intelligence and human intelligence, and more.

The field of photonics has seen significant advances during the past decades, to the point where it is now an integral part of high-speed, international communications. For general processing photonics is currently less common, but is the subject of significant research. Unlike most photonic circuits which are formed using patterns etched into semiconductor mask using lithography, purely light-based circuits are a tantalizing possibility. This is the focus of a recent paper (press release, ResearchGate) in Nature Photonics by [Tianwei Wu] and colleagues at the University of Pennsylvania.
What is somewhat puzzling is that despite the lofty claims of this being ‘the first time’ that such an FPGA-like device has been created for photonics, this is far from the case, as evidenced by e.g. a 2017 paper by [Kaichen Dong] and colleagues (full article PDF) in Advanced Materials. Here the researchers used a slab of vanadium dioxide (VO2) with a laser to heat sections to above 68 °C where the material transitions from an insulating to a metallic phase and remains that way until the temperature is lowered again. The μm-sized features that can be created in this manner allow for a wide range of photonic devices to be created.
What does appear to be different with the photonic system presented by [Wu] et al. is that it uses a more traditional 2D approach, with a slab of InGaAsP on which the laser pattern is projected. Whether it is more versatile than other approaches remains to be seen, with the use of fully photonic processors in our computers still a long while off, never mind photonics-accelerated machine learning applications.
Every day, tens of thousands of songs are released. This constant stream of options makes it difficult for streaming services and radio stations to choose which songs to add to playlists. To find the ones that will resonate with a large audience, these services have used human listeners and artificial intelligence. This approach, however, lingering at a 50% accuracy rate, does not reliably predict if songs will become hits.
Now, researchers in the US have used a comprehensive machine learning technique applied to brain responses and were able to predict hit songs with 97% accuracy.
“By applying machine learning to neurophysiologic data, we could almost perfectly identify hit songs,” said Paul Zak, a professor at Claremont Graduate University and senior author of the study published in Frontiers in Artificial Intelligence. “That the neural activity of 33 people can predict if millions of others listened to new songs is quite amazing. Nothing close to this accuracy has ever been shown before.”
Airbnb CEO Brian Chesky isn’t afraid of artificial intelligence displacing jobs. In fact, he thinks it’ll create more of them — particularly in the world of entrepreneurship.
Since ChatGPT started gaining popularity last winter, tech icons from Apple co-founder Steve Wozniak to billionaire entrepreneur Mark Cuban have admitted they’re worried that AI will replace human workers in just about every industry.
But they’re forgetting something, Chesky recently told the “This Week in Startups” podcast: We don’t even know what kinds of jobs it’ll create.
Rocks and minerals contribute essential raw materials for any civilization, and in a technological society minerals (and the rare elements they contain) are especially sought after. In the past, most discoveries of mineral deposits have resulted from perseverance and luck.
In the last 200 years scientists realized that minerals are not distributed randomly. Many of the over 5,000 different minerals occurring on Earth exist in a so-called paragenesis. A paragenesis is a mineral assemblage formed under specific physico-chemical rules, like a certain chemical composition of the host rock or when the right conditions — like temperature and pressure — are met.
A machine learning model can predict the locations of minerals on Earth — and potentially other planets — by taking advantage of patterns in mineral associations.
Self-driving efforts today focus on particular niches, such as the urban robotaxi, delivery, trucking or freeeway driving. Other than Tesla, most major players don’t have a focus on the general personal robocar — a car which consumers will buy, which will drive them door to door on city streets and most other roads. Tesla is very far behind other teams, and barely counts in the minds of many in the industry, thought it gets the most press. A few startups pursue the full robocar dream, but thinking has changed.
In spite of that perceived dream, that is not what the industry is building, or what it is going to release for some time. It may be some time before you can buy a car for yourself with this ability, not just because it’s hard, but because it’s not where the money is. This has led some people to think that robocars are still very far away, and also to a common perception that the technology is many years behind what people expected. Indeed, some people expected, or at least hoped for, faster timelines, but others did not.
The public has a different perception, in part because of Tesla, but also because of a document written over a decade ago by NHTSA (the federal road safety agency) and now manged by the Society of Automotive Engineers known as “the levels.” This document filled the need for a taxonomy of self-driving, but it was written by non-developers when the technology was immature. As such it’s largely useless and even counterproductive, but people are so hungry for a taxonomy that it still is often referred to. The leading teams (mostly tech companies not auto OEMs) do not use these level or attempt to adhere to them. They are mostly a way to talk about the dwindling role of the human in the operation of a self-driving car, a bit like a document about the role of the horse in the horseless carriage.
