Scientists found a way to cool quantum computers using noise

Quantum computers only work when they are kept extremely cold. The problem is that today’s cooling systems also create noise, which can interfere with the fragile quantum information they are supposed to protect. Researchers at Chalmers University of Technology in Sweden have now introduced a new type of minimal quantum “refrigerator” that turns this challenge into an advantage. Instead of fighting noise, the device partially relies on it to operate. The result is highly precise control over heat and energy flow, which could help make large scale quantum technology possible.

Quantum technology is widely expected to reshape major areas of society. Potential applications include drug discovery, artificial intelligence, logistics optimization, and secure communications. Despite this promise, serious technical barriers still stand in the way of real world use. One of the most difficult challenges is maintaining and controlling the delicate quantum states that make these systems work.

New recyclable protein textiles could cut microplastic pollution and lower clothing waste

The textile industry produces a substantial portion of the world’s waste, with only about 12% of fiber materials ending up in recycling. Textiles also account for much of the microplastics in oceans. During every wash cycle, synthetic fibers shed microplastics that are flushed down the drain and eventually enter aquatic environments. Increasing textile recycling alone won’t solve this problem because most petrochemical-based fibers are difficult to recycle and continue to release persistent microplastics throughout their life cycle.

Engineers from Washington University in St. Louis may have a solution, thanks to dedicated synthetic biology work in the lab of Fuzhong Zhang, the Francis F. Ahmann Professor in the Department of Energy, Environmental & Chemical Engineering in the McKelvey School of Engineering and co-director of Synthetic Biology Manufacturing of Advanced Materials Research Center (SMARC).

The results of that work, now published in the journal Advanced Materials, created protein-based materials, which are produced in bioreactors (think giant brewing tanks) using genetically engineered microbes. These materials can be readily recycled after use and remade into the same fibers over multiple cycles. In addition, any microparticles, if released from these fibers during washing, would be biodegradable.

Hidden small RNA in cholera bacterium helps determine whether it can infect humans

Scientists from St. Jude Children’s Research Hospital have uncovered what gives Vibrio cholerae, the bacterium that causes cholera, the ability to colonize the human gut. The researchers found that a small RNA embedded within another gene controls where cholera thrives, a discovery that could improve prediction and prevention strategies. The study is published in the journal Nature Communications.

Infectious diseases remain the leading cause of pediatric mortality worldwide. V. cholerae causes a severe diarrheal disease leading to more than 143,000 deaths and millions of cases each year, primarily affecting young children. While there are many strains of the V. cholerae species, only one can infect humans. The reason for this has been unclear for 50 years, hampering efforts to predict and prevent outbreaks.

“For decades, we’ve been trying to understand what allows cholera to infect humans,” said corresponding author Salvador Almagro-Moreno, Ph.D., St. Jude Department of Host-Microbe Interactions. “The answer was right in front of us the whole time—this small RNA hiding inside another gene is the real culprit.”

Scientists discover tiny gut particles that may drive aging and chronic disease

A new study suggests microscopic particles from the gut may actively drive inflammation and chronic diseases associated with aging. Remarkably, gut particles from young animals appeared to counter some aging-related damage in older animals, hinting at new possibilities for future treatments.

Metabolism by ex vivo cultures of human stool increases the activity of coumarin, a widespread antioxidant from herbal supplements

Mingolelli et al. characterize microbiome metabolism of coumarin in ex vivo cultures from human stool. Seventeen gut species reduce coumarin to 3,4-dihydrocoumarin and melilotic acid, including E. coli, through an N-ethylmaleimide-reductase-dependent pathway. Gut metabolites demonstrate increased antioxidant activity compared to either coumarin or its host metabolite, umbelliferone.

SpaceX is skipping the booster catch on Starship V3’s debut flight — and the reason quietly reveals which milestone Musk actually cares about hitting before Artemis

SpaceX will not attempt to catch the Super Heavy booster on Starship V3’s debut flight. The booster will steer itself to a soft splashdown in the Gulf of Mexico instead of returning to the launch tower’s mechanical arms — the maneuver that became the defining image of the program on multiple V2 flights. For a company that has made spectacle a core part of its engineering culture, skipping the catch is a tell. It signals what Elon Musk and his engineers actually care about getting right on this flight, and it isn’t the part that makes for a good replay.

Astrophysicists use ‘space archaeology’ to trace the history of a spiral galaxy

Billions of years ago, a young spiral galaxy began to grow in a crowded part of the universe. It pulled in gas and small companion galaxies, slowly building up the bright central region and sweeping spiral arms we see today.

In a new study published in March 2026, my colleagues and I used this galaxy’s chemical fingerprints to reconstruct its life story in detail.

Astronomers want to know how spiral galaxies like our own Milky Way came to be, as these galaxies can give us hints about how the elements we rely on, such as oxygen, were created and spread through space over time.
