Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet transiting a distant star. The newfound alien world, designated TOI-6692 b, is the size of Jupiter and has an orbital period of about 130 days. The discovery was presented in a paper published January 22 on the arXiv pre-print server.
TESS is conducting a survey of about 200,000 bright stars near the sun with the aim of searching for transiting exoplanets. To date, more than 7,800 potential planets (known as TESS Objects of Interest) have been cataloged using this satellite, with 733 of those discoveries officially verified.
A University of Missouri researcher is pioneering an innovative solution to remove tiny bits of plastic pollution from our water. Mizzou’s Susie Dai recently applied a revolutionary strain of algae toward capturing and removing harmful microplastics from polluted water. Driven by a mission to improve the world for both wildlife and humans, Dai also aims to repurpose the collected microplastics into safe, bioplastic products such as composite plastic films.
“Microplastics are pollutants found almost everywhere in the environment, such as in ponds, lakes, rivers, wastewater and the fish that we consume,” Dai, a professor in the College of Engineering and principal investigator at the Bond Life Sciences Center, said. “Currently, most wastewater treatment plants can only remove large particles of plastic, but microplastics are so small that they slip through and end up in drinking water, polluting the environment and harming ecosystems.”
The findings are published in the journal Nature Communications.
A large, decades-long population study suggests that the relationship between diet and dementia may hinge on subtle chemical differences in everyday foods and water.
Next, the study’s authors will examine whether more ZEVs are associated with fewer asthma-related hospitalizations and emergency room visits.
Their work adds to the extensive research on whether EVs are better for the planet long-term than their gas-powered counterparts. Despite imperfections such as mining, the findings are clear on that front. The USC team is showing that when it comes to the air we breathe and public health, the benefits of EVs are undeniable.
“These findings show that cleaner air isn’t just a theory—it’s already happening in communities across California,” declared Sandrah Eckel, the study’s lead author.
Transparent electrodes transmit light while conducting electricity and are increasingly important in bioelectronic and optoelectronic devices. Their combination of high optical transparency, low electrical resistance, and mechanical flexibility makes them well suited for applications such as displays, solar cells, and wearable or implantable technologies.
In a significant advancement, researchers led by Professor Wonsuk Jung at Chungnam National University in the Republic of Korea have introduced a new fabrication technique called one-step free patterning of graphene, or OFP-G, which enables high-resolution patterning of large-area monolayer graphene with feature sizes smaller than 5 micrometers, without the use of photoresists or chemical etching.
Published Microsystems & Nanoengineering, the method addresses a key limitation of conventional microelectrode fabrication, where lithographic processes often damage graphene and degrade its electrical performance.

Can quantum tunneling occur at macroscopic scales? Neil deGrasse Tyson and comedian Chuck Nice sit down with John Martinis, UCSB physicist and 2025 Nobel Prize winner in Physics, to explore superconductivity, quantum tunneling, and what this means for the future of quantum computing.
What exactly is macroscopic quantum tunneling, and why did it take decades for its importance to be recognized? We’ve had electrical circuits forever, so what did Martinis discover that no one else saw? If quantum mechanics usually governs tiny particles, why does a superconducting circuit obey the same rules? And what does superconductivity really mean at a quantum level?
How can a system cross an energy barrier it doesn’t have the energy to overcome? What is actually tunneling in a superconducting wire, and what does it mean to tunnel out of superconductivity? We break down Josephson Junctions, Cooper pairs, and other superconducting lingo. Does tunneling happen instantly, or does it take time? And what does that say about wavefunction collapse and our assumptions about instantaneous quantum effects?
Learn what a qubit is and why macroscopic quantum effects are important for quantum computing. Why don’t quantum computers instantly break all encryption? How close are we to that reality, and what replaces today’s cryptography when it happens? Is quantum supremacy a scientific milestone, a geopolitical signal, or both? Plus, we take cosmic queries from our audience: should quantum computing be regulated like nuclear energy? Will qubits ever be stable enough for everyday use? Will quantum computers live in your pocket or on the dark side of the Moon? Can quantum computing supercharge AI, accelerate discovery, or even simulate reality itself? And finally: if we live in a simulation, would it have to be quantum all the way down?

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.
Of the more than 4,500 stars known to have planets, one puzzling statistic stands out. Even though nearly all stars are expected to have planets and most stars form in pairs, planets that orbit both stars in a pair are rare.
Of the more than 6,000 extrasolar planets, or exoplanets, confirmed to date—most of them found by NASA’s Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS)—only 14 are observed to orbit binary stars. There should be hundreds. Where are all the planets with two suns, like Tatooine in Star Wars?
For the first time, scientists have used ultraviolet (UV) light, a low-cost and readily available energy source, to successfully synthesize more sustainable and recyclable polymer materials. Led by green chemistry experts at Flinders University, the development is a major step in making polymers high in sulfur content for more sustainable plastic alternatives using waste materials.
Their paper, “Making and Unmaking Poly(trisulfides) with Light: Precise Regulation of Radical Concentrations via Pulsed LED Irradiation” is published in the Journal of the American Chemical Society.
Industrial dye pollution remains one of the most persistent and hazardous challenges in global wastewater management. The dyes from textile and chemical manufacturing sectors are difficult to remove, non-biodegradable, and can be toxic to plants, animals, and humans. However, conventional treatment technologies for dyes often fail to efficiently purify the wastewater without significant trade-offs.
To remedy this issue, researchers from Tohoku University developed a three-dimensional covalent organic framework (COF), TU-123, that enables highly efficient and selective removal of anionic dyes from contaminated water.
The highly porous COF acts like a sponge—trapping dyes for easier separation. This work establishes a new structural blueprint for constructing highly connected imidazole-linked three-dimensional COFs. Furthermore, it opens sustainable pathways for advanced wastewater purification technologies.
