Researchers have developed two unique energy-efficient and cost-effective systems that use urea found in urine and wastewater to generate hydrogen. The unique systems reveal new pathways to economically generate 'green' hydrogen, a sustainable and renewable energy source, and the potential to remediate nitrogenous waste in aquatic environments.

A team partially replaced lithium in a lithium antimonide compound with the metal scandium. This creates specific gaps, so-called vacancies, in the crystal lattice of the conductor material. These gaps help the lithium ions to move more easily and faster, resulting in a new world record for ion conductivity.

Researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared spectra.

A research team used the German environmental satellite EnMAP (Environmental Mapping and Analysis Program) to simultaneously detect the two key air pollutants carbon dioxide (CO2) and nitrogen dioxide (NO2) in emission plumes from power plants -- with an unprecedented spatial resolution of just 30 meters. The newly developed method allows for tracking of industrial emissions from space with great precision and enables atmospheric processes to be analyzed in detail.

A significant advancement in molecular engineering has produced a large, hollow spherical shell nanostructure through the self-assembly of peptides and metal ions, report researchers from Japan. This dodecahedral link structure, measuring 6.3 nanometers in diameter, was achieved by combining geometric principles derived from knot theory and graph theory with peptide engineering. The resulting structure demonstrates remarkable stability while featuring a large inner cavity suitable for encapsulating macromolecules, opening pathways for producing complex artificial virus capsids.

A team of researchers has developed a new strategy for identifying hazardous pollutants in soil -- even ones that have never been isolated or studied in a lab.

New bismuth-based organic-inorganic hybrid materials show exceptional sensitivity and long-term stability as X-ray detectors, significantly more sensitive than commercial X-ray detectors. In addition, these materials can be produced without solvents by ball milling, a mechanochemical synthesis process that is environmentally friendly and scalable. More sensitive detectors would allow for a reduction in the radiation exposure during X-ray examinations.

Carbyne, a one-dimensional chain of carbon atoms, is incredibly strong for being so thin, making it an intriguing possibility for use in next-generation electronics, but its extreme instability made it nearly impossible to produce at all, let alone produce enough of it for advanced studies. Now, an international team of researchers may have a solution.

Just like humans, chimps have rhythm when drumming, which suggests that the trait evolved in our common ancestor

We tend to think of habitability in terms of individual planets and their potential to host life. But barring outliers like rogue planets with internal heating or icy moons with subsurface oceans created by tidal heating, it's exoplanet/star relationships that generate habitability, not individual planets. New research emphasizes that fact.

Our bodies emit a stream of low-energy photons, and now experiments in mice have revealed that this ghostly glow is cut off when we die

With season 2 unfolding, the science of the fungal horror drama is becoming shakier. It is a pity that the creators haven’t thought about terrifying scenarios of real-life infection, says Corrado Nai
