A ‘cage of cages’ is how scientists have described a new type of porous material, unique in its molecular structure, that could be used to trap carbon dioxide and another, more potent greenhouse gas.
Synthesized in the lab by researchers in the UK and China, the material is made in two steps, with reactions assembling triangular prism building blocks into larger, more symmetrical tetrahedral cages – producing the first molecular structure of its kind, the team claims.
The resulting material, with its abundance of polar molecules, attracts and holds greenhouse gasses such as carbon dioxide (CO2) with strong affinity. It also showed excellent stability in water, which would be critical for its use in capturing carbon in industrial settings, from wet or humid gas streams.
Borophene is already thinner and more conductive than graphene, and scientists have altered it to make it even more special.

What is the potential impact of humanoid robots on human labor?
—Humanoid robots are on the verge of disrupting human labor across various industries, leading to a new era of material superabundance and prosperity within the next 10 to 20 years.
The newfound black hole, an intense, light-trapping abyss which has been named Gaia BH3, lurks just 1,926 light-years from Earth in the Aquila constellation. (That makes it the second closest black hole to Earth after Gaia BH1, which resides at 1,500 light-years away and is three times lighter than Gaia BH3.) The so-called “sleeping giant” — so named because unlike its ilk, the dormant black hole doesn’t appear to be shredding its companion star to pieces — birthed out of the imminent collapse of a once-massive star. It is the first direct link between a black hole and a progenitor star that was deprived of metals heavier than hydrogen and helium, according to the new study published in April in the journal Astronomy and Astrophysics.
The discovery confirms a leading theory of stellar evolution that posits high-mass black holes are remnants of stars that are low on metals. Such metal-poor stars have damped mass-eroding winds compared to their metal-rich counterparts, and thus have more material available to form heavier black holes. Astronomers normally time announcements of science discoveries at the same time as data release, in this case no sooner than early 2026, but “you cannot hide this kind of discovery from the community for two years,” says Panuzzo. “It is a unique case of publication based on the preliminary data because the data is exceptional and also something that’s very interesting for the community.”
“We employed this configuration for the first time to characterize the signal field emerging from a resonantly excited plasmonic sample,” says Francesca Calegari, lead scientist at DESY, physics Professor at Universität Hamburg and a spokesperson of the Cluster of Excellence “CUI: Advanced Imaging of Matter.”
The difference of the reconstructed pulse with plasmon interaction to the reference pulse allowed the scientists to trace the emergence of the plasmon and its fast decay which they confirmed by electrodynamic model calculations.
“Our approach can be used to characterize arbitrary plasmonic samples in ambient conditions and in the far-field,” adds CUI scientist Prof. Holger Lange. Additionally, the precise characterization of the laser field emerging from nanoplasmonic materials could constitute a new tool to optimize the design of phase-shaping devices for ultrashort laser pulses.

NYU Abu Dhabi researchers have unveiled a novel 2D material improving optical modulation for advanced systems and communications.
Responding to the increasing demand for efficient, tunable optical materials capable of precise light modulation to create greater bandwidth in communication networks and advanced optical systems, a team of researchers at NYU Abu Dhabi’s Photonics Research Lab (PRL) has developed a novel, two-dimensional (2D) material capable of manipulating light with exceptional precision and minimal loss.
Tunable optical materials (TOMs) are revolutionizing modern optoelectronics, electronic devices that detect, generate, and control light. In integrated photonics circuits, precise control over the optical properties of materials is crucial for unlocking groundbreaking and diverse applications in light manipulation. Two-dimensional materials like Transition Metal Dichalcogenides (TMDs) and graphene exhibit remarkable optical responses to external stimuli. However, achieving distinctive modulation across a short-wave infrared (SWIR) region while maintaining precise phase control at low signal loss within a compact footprint has been a persistent challenge.
