How does a cloud stay cool under direct sunlight––or seem to vanish in infrared? In nature, phenomena like white cumulus clouds, gray storm systems, and even the hollow hairs of polar bears offer remarkable lessons in balancing temperature, color and invisibility. Inspired by these atmospheric marvels, researchers have now created a nanoscale “cloud” metasurface capable of dynamically switching between white and gray states—cooling or heating on demand––all while evading thermal detection.

Researchers demonstrate giant photonic isolation and gyration https://lifeboat.com/blog/2025/06/researchers-demonstrate-giant-photonic-isolation-and-gyration https://lifeboat.com/blog/2025/06/researchers-demonstrate-giant-photonic-isolation-and-gyration#respond Sat, 28 Jun 2025 15:12:10 +0000 https://lifeboat.com/blog/2025/06/researchers-demonstrate-giant-photonic-isolation-and-gyration

The original goal of the study was to get this asymmetry to a point of perfect isolation—that is, where there is zero interaction in one direction. They successfully achieved this goal by demonstrating a giant optical isolation effect, where the propagation of light in one direction was a million times easier than in the opposite direction.

But while exploring their test devices, the engineers encountered a surprise. Their approach was so efficient that they could even get past the isolation point to where the sign of the coupling simply flipped and the phase became direction dependent. This was something that had not been seen before in time modulated coupling and is an easy path to photonic gyration.

Going forward, the Illinois researchers will work to expand their findings. They are working with their partners specializing in condensed matter to explore how longer and more elaborate chains of resonators with this kind of tunable couplings could answer fundamental questions on topological physics. Simultaneously, from an engineering standpoint, they aim to create a pure gyrator which is a universal building block of many nonreciprocal devices.

Artificial photosynthesis system surpasses key efficiency benchmark for direct solar-to-hydrogen conversion https://lifeboat.com/blog/2025/06/artificial-photosynthesis-system-surpasses-key-efficiency-benchmark-for-direct-solar-to-hydrogen-conversion https://lifeboat.com/blog/2025/06/artificial-photosynthesis-system-surpasses-key-efficiency-benchmark-for-direct-solar-to-hydrogen-conversion#respond Fri, 27 Jun 2025 18:06:37 +0000 https://lifeboat.com/blog/2025/06/artificial-photosynthesis-system-surpasses-key-efficiency-benchmark-for-direct-solar-to-hydrogen-conversion

A research team affiliated with UNIST has introduced a cutting-edge modular artificial leaf that simultaneously meets high efficiency, long-term stability, and scalability requirements—marking a major step forward in green hydrogen production technology essential for achieving carbon neutrality.

Jointly led by Professors Jae Sung Lee, Sang Il Seok, and Ji-Wook Jang from the School of Energy and Chemical Engineering, this innovative system mimics natural leaves by producing solely from sunlight and water, without requiring external power sources or emitting during the process—a clean hydrogen production method. The study is published in Nature Communications.

Unlike conventional photovoltaic-electrochemical (PV-EC) systems, which generate electricity before producing hydrogen, this direct solar-to-chemical conversion approach reduces losses associated with and minimizes installation footprint. However, prior challenges related to low efficiency, durability, and scalability hindered commercial deployment.

Researcher discusses trapping single atoms and putting them to work in emerging quantum technologies https://lifeboat.com/blog/2025/06/researcher-discusses-trapping-single-atoms-and-putting-them-to-work-in-emerging-quantum-technologies https://lifeboat.com/blog/2025/06/researcher-discusses-trapping-single-atoms-and-putting-them-to-work-in-emerging-quantum-technologies#respond Fri, 27 Jun 2025 11:23:49 +0000 https://lifeboat.com/blog/2025/06/researcher-discusses-trapping-single-atoms-and-putting-them-to-work-in-emerging-quantum-technologies

Blink and you might miss it, but if you keep your eye on the monitors in professor Sebastian Will’s lab, you’ll catch a series of single-second flashes that light up the screen. Each flash is an atom of strontium, a naturally occurring alkaline-earth metal, being briefly captured and held in place by “tweezers” made of laser light. “We can see single atoms,” says graduate student Aaron Holman. “Seeing those never gets old.”

The lab saw its first atom at the end of 2022, after two years of constructing the experimental setup—a complicated and carefully calibrated series of atomic sources, vacuum chambers, magnets, electronics, and lasers that trap and place them into custom arrangements—from scratch.

Holman, currently a 5th-year Ph.D. student in Physics, helped build the “TweeSr” project, as it’s referred to in the lab, from the ground up. A pure atomic, molecular, and optical (AMO) physicist at heart, he’s now working on ways to turn fundamental research on how atoms, molecules, and light interact into new technologies with collaborators at Columbia Engineering. He’s also heading toward bigger scales as part of a that is currently under construction.

Navier–Stokes existence and smoothness https://lifeboat.com/blog/2025/06/navier-stokes-existence-and-smoothness https://lifeboat.com/blog/2025/06/navier-stokes-existence-and-smoothness#respond Thu, 26 Jun 2025 22:05:58 +0000 https://lifeboat.com/blog/2025/06/navier-stokes-existence-and-smoothness

The problem concerns the mathematical properties of solutions to the Navier–Stokes equations, a system of partial differential equations that describe the motion of a fluid in space. Solutions to the Navier–Stokes equations are used in many practical applications. However, theoretical understanding of the solutions to these equations is incomplete. In particular, solutions of the Navier–Stokes equations often include turbulence, which remains one of the greatest unsolved problems in physics, despite its immense importance in science and engineering.
