New drug discovery technology developed by the University of Bath (UK) harnesses bacteria to do the hard work of medicinal chemistry by creating drug candidates and testing them inside living cells.

In Physics of Fluids, researchers from Brown University present two related studies about thin film fluid flows in the kitchen: one about the relationship between how long it takes to tip the remaining liquid out of a container and its viscosity, and the other about the ideal time to wait before dumping water out of a wok to minimize rusting — it’s more effective to wait a few minutes to let the water accumulate so there’s more to pour out.

Luna Labs has selected UNC Greensboro (UNCG) chemistry professor Nicholas Oberlies to lead a NASA-funded project exploring whether fungi can be grown into building materials for construction on the moon and Mars. The project will investigate whether certain fungi can be combined with regolith — loose rock and soil found on the surface of the moon and other planets — to create materials that could one day support construction in places other than Earth.

Dogs come in all shapes and sizes: from giant fluffy Newfoundlands to tiny short-haired Chihuahuas. And many furry companions like to spend their days inside near their humans. An initial study published in ACS’ Environmental Science & Technology reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did.

Aromatic medicinal plants derive their therapeutic value from complex mixtures of volatile compounds, yet the genetic logic that shapes these chemical profiles has long remained elusive. 

A new catalyst strategy developed at Institute of Science Tokyo uses BaSi₂ as a support for nickel and cobalt to decompose ammonia at lower temperatures. By forming unique ternary transition metal–nitrogen–barium intermediates that facilitate nitrogen coupling, the system lowers the energy barrier for ammonia decomposition. This enables nickel- and cobalt-based catalysts to achieve high hydrogen-production activity at reduced temperatures, matching the performance of ruthenium while relying on Earth-abundant metals for cleaner hydrogen generation.

Diastereomers are molecules with identical structures that are not mirror images of each other, described as anti or syn for molecules without rings. Researchers at the University of Osaka developed a strategy for using a rigid cage-like molecule to produce an anti-diastereomer in high yield. This diastereomer can only be obtained as a minor byproduct by traditional methods. The strategy is expected to become a key technology for making medicines and other bioactive substances.
