Researchers have produced, stored, and retrieved quantum information for the first time, a critical step in quantum networking.

The ability to share quantum information is crucial for developing quantum networks for distributed computing and secure communication. Quantum computing will be useful for solving some important types of problems, such as optimizing financial risk, decrypting data, designing molecules, and studying the properties of materials.

“Interfacing two key devices together is a crucial step forward in allowing quantum networking, and we are really excited to be the first team to have been able to demonstrate this.” —

From the brightness variations of its host star, an exoplanet ’s size and other properties can be determined. In order to avoid mistakes, the star’s magnetic field is decisive.

700 light years away from Earth in the constellation Virgo, the planet WASP-39b orbits the star WASP-39. The gas giant, which takes little more than four days to complete one orbit, is one of the best-studied exoplanets.

Shortly after its commissioning in July 2022, NASA’s James Webb Space Telescope turned its high-precision gaze on the distant planet. The data revealed evidence of large quantities of water vapor, of methane and even, for the first time, of carbon dioxide in the atmosphere of WASP-39b. A minor sensation!

Researchers have quantified a pathway for the formation of molecular oxygen from the interaction of carbon dioxide with electrons, key information for searches of life on other worlds.

So far, life is only known to exist on Earth. But that hasn’t stopped scientists from searching for signs of living creatures on other planets. Those searches intensified with the deployment of the JWST observatory, which astronomers are using to characterize the atmospheres of far-off worlds in the hope of finding the signals of molecules that signify the presence of life (see News Feature: The Skinny on Detecting Life with the JWST). But for that to work, scientists need to know all the possible sources of atmospheric molecules. Now Lucas Sigaud of the Fluminense Federal University, Brazil, and his colleagues have uncovered a pathway for forming an oxygen molecule (O2]. The detailed measurements of the pathway provide key inputs for models used in planetary-life searches.

Atmospheric water generators can save millions of lives due to new drought conditions even bringing water from air in the desert climates.

• Water scarcity continues to be a pervasive global challenge, cutting across developed and emerging markets, climates and socio-political dynamics.
• Atmospheric water generation (AWG) technology is a promising emergency solution that can immediately generate drinkable water using moisture in the air.
• Distribution of atmospheric water generation technology to communities in need can serve as an effective stopgap measure for municipalities facing immediate clean water shortages.

The statistics underpinning water scarcity are dire and noteworthy – approximately 770 million people lack access to clean water. That is one in ten people on the planet. The average woman in rural Africa walks 6 kilometres (about 3.7 miles) daily to haul 40 pounds of water.

Scientists seem to be close to creating a “one-and-done” vaccine that can protect against any strain of a virus with just one shot.

In a press release from the University of California — Riverside, one of the researchers behind the new RNA vaccine, Rong Hai, explained why he and his colleagues are so excited about their experimental — and allegedly universal — shot.

“What I want to emphasize about this vaccine strategy is that it is broad,” said Hai, a virologist and coauthor of a new paper on the vaccine candidate in the Proceedings of the National Academy of Sciences. “It is broadly applicable to any number of viruses, broadly effective against any variant of a virus, and safe for a broad spectrum of people.”

Scientists have demonstrated that facial recognition technology can predict a person’s political orientation with a surprising level of accuracy.

Researchers have demonstrated that facial recognition technology can predict political orientation from neutral expressions with notable accuracy, posing significant privacy concerns. This finding suggests our faces may reveal more personal information than previously understood.

We lost a really great human today – philosopher Daniel C. Dennett.

Dan was a kind, honest, generous guy. He had a brilliant mind – insightful, critical, with an encyclopedic knowledge of pithy analogies and clinical examples (“intuition pumps” he called them), as well as who came up with them. And despite all of his experience and accomplishments, he always had a kind of childish excitement about new ideas, and new experiments. What he liked best was new insights, wild ideas, honest argument. I first heard the concept of “steel-manning” from him (opposite of “straw man” – putting forth the strongest, best version of an argument you want to critique). He was not interested in cheap wins or rhetorical bullying – he wanted to get to the best version of every story about nature and about ourselves.

I first came into contact with Dan through his books. As a teenager, Brainstorms, Elbow Room, and The Intentional Stance were a fantastic introduction to the most interesting questions, and ways of thinking about them. My dad and I would hit the bookstores every Saturday and there was no way a Dennett book would escape us if a new one came out. We had lots of great times discussing the topics in his books. I eventually was able to ask Dan to sign a few of them for dad, as birthday presents.
