Quantum entanglement—a connection between particles that produces correlations beyond what is classically possible—will be the backbone of future quantum technologies, including secure communication, cloud quantum computing, and distributed sensing. But entanglement is fragile; noise from the environment degrades entangled states over time, leaving scientists searching for methods to improve the fidelity of noisy entangled states.

Now, researchers at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME), University of Illinois Urbana-Champaign, and Microsoft have shown that it is fundamentally impossible to design a single one-size-fits-all protocol to counteract that noise.

“In , we often hope for a protocol that works in all scenarios—a kind of cure-all,” said Asst. Prof. Tian Zhong, senior author of the new work published in Physical Review Letters. “This result shows that when it comes to purifying entanglement, that’s simply too good to be true.”

A biotech startup from the U.S. is aiming to reshape the construction industry with the launch of a groundbreaking new material that mimics the look and feel of natural wood while outperforming high-grade steel in strength and durability.

Maryland-based firm InventWood, revealed that their engineering wood product called Superwood is a result of molecular-level transformation that turns natural wood into a material up to a dozen times stronger and 10 times tougher than its original form.

Anyone who speculates on likely events ahead of time and prepares accordingly can react quicker to new developments. What practically every person does every day, consciously or unconsciously, is also used by modern computer processors to speed up the execution of programs. They have so-called speculative technologies which allow them to execute instructions on reserve that experience suggests are likely to come next. Anticipating individual computing steps accelerates the overall processing of information.

However, what boosts computer performance in normal operation can also open up a backdoor for hackers, as recent research by computer scientists from the Computer Security Group (COMSEC) at the Department of Information Technology and Electrical Engineering at ETH Zurich shows.

The computer scientists have discovered a new class of vulnerabilities that can be exploited to misuse the prediction calculations of the CPU (central processing unit) in order to gain unauthorized access to information from other processor users. They will present their paper at the 34th USENIX Security Symposium (USENIX 2025), to be held August 13–15, 2025, in Seattle.

Researchers from the University of Oklahoma have made significant advances in a promising technology for efficient energy conversion and chemical processing. Two recent studies involving protonic ceramic electrochemical cells, called PCECs, address significant challenges in electrochemical manufacturing and efficiency. These innovations are a crucial step toward reliable and affordable solutions for hydrogen production and clean energy storage.

The studies were led by Hanping Ding, Ph.D., an assistant professor in the School of Aerospace and Mechanical Engineering at the University of Oklahoma.

PCECs have traditionally struggled to maintain performance under the required for commercial use. In a study featured in Nature Synthesis, Ding and his colleagues reported a new approach that eliminates the need for cerium-based materials, which are prone to breakdown under high steam and heat.

Northwestern University Trustee Kimberly K. Querrey (’22, ’23 P) has made a $10 million gift to create and enhance the Querrey Simpson Institute for Regenerative Engineering at Northwestern University (QSI RENU), bringing her total giving to the institute to $35 million. The new institute will advance the development of medical tools that empower the human body to heal, focusing on the regeneration or reconstruction of various tissues and organs, such as the eyes, cartilage, spinal cord, heart, muscle, bone and skin.

The Querrey Simpson Institute for Regenerative Engineering at Northwestern University will advance research to regenerate and reconstruct tissues and organs.

Guillermo Ameer, director of the new Querrey Simpson Institute for Regenerative Engineering at Northwestern University, showcases his bioresorbable bandage, which delivers electrotherapy to wounds, accelerating diabetic ulcer healing and dissolving safely after use. QSI RENU combines engineering, biology, medicine and data science to develop technologies for tissue and organ function.

A research team has developed a high-performance supercapacitor that is expected to become the next generation of energy storage devices. With details published in the journal Composites Part B: Engineering, the technology developed by the researchers overcomes the limitations of existing supercapacitors by utilizing an innovative fiber structure composed of single-walled carbon nanotubes (CNTs) and the conductive polymer polyaniline (PANI).

Compared to conventional batteries, supercapacitors offer faster charging and higher power density, with less degradation over tens of thousands of charge and discharge cycles. However, their relatively low energy density limits their use over long periods of time, which has limited their use in practical applications such as and drones.

Researchers led by Dr. Bon-Cheol Ku and Dr. Seo Gyun Kim of the Carbon Composite Materials Research Center at the Korea Institute of Science and Technology (KIST) and Professor Yuanzhe Piao of Seoul National University (SNU), uniformly chemically bonded single-walled carbon nanotubes (CNTs), which are highly conductive, with polyaniline (PANI), which is processable and inexpensive, at the nanoscale.

NASA’s James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to precisely analyze molecular components such as water vapor and sulfur dioxide in exoplanet atmospheres. The key to this analysis, where each molecule exhibits a unique spectral “fingerprint,” lies in highly sensitive photodetector technology capable of measuring extremely weak light intensities.

Recently, KAIST researchers have developed an innovative capable of detecting a broad range of mid-infrared spectra, garnering significant attention. A research team led by Professor SangHyeon Kim from the School of Electrical Engineering has developed a mid-infrared photodetector that operates stably at room temperature, marking a major turning point for the commercialization of ultra-compact optical sensors.

The work is published in the journal Light: Science & Applications.

Arianna Gleason is an award-winning scientist at the Department of Energy’s SLAC National Accelerator Laboratory who studies matter in its most extreme forms—from roiling magma in the center of our planet to the conditions inside the heart of distant stars. During Fusion Energy Week, Gleason discussed the current state of fusion energy research and how SLAC is helping push the field forward.

Fusion is at the heart of every star. The tremendous pressure and temperature at the center of a star fuses atoms together, creating many of the elements you see on the periodic table and generating an immense amount of energy.

Fusion is exciting, because it could provide unlimited energy to our . We’re trying to replicate here on Earth, though it’s a tremendous challenge for science and engineering.

Imagine you are playing the guitar—each pluck of a string creates a sound wave that vibrates and interacts with other waves. Now shrink that idea down to a small single molecule, and instead of sound waves, picture vibrations that carry heat.

A team of engineers and at the Paul M. Rady Department of Mechanical Engineering at CU Boulder has recently discovered that these tiny thermal vibrations, otherwise known as phonons, can interfere with each other just like musical notes—either amplifying or canceling each other, depending on how a molecule is “strung” together.

The research is published in the journal Nature Materials.
