Scientists create “virtual sort nanomachines” that use electron beams to manipulate graphene oxides
Dynamic graphene oxide sorting overview: (a) The system uses an electron beam on silicon nitride to create an electric field pattern that generates a force opposed to the graphene oxide sheet. (b) Start the state with a graphene oxide sheet in the solution. (c) An intermediate step showing a sheet pulled towards the pattern by an electroosmotic flow. (d) The…

Cool Science: Researchers create small biological tools using frozen ethanol
Credit: Eric Stan Imagine drawing something delicate like a living cell without hurting it. Researchers at the University of Missouri made this discovery using a combination of unexpected tools: frozen ethanol, electron beams, and purple-colored microorganisms. By proceeding with a method called ice lithography, the team was able to directly etch the very small, detailed patterns onto fragile biological surfaces.…

Flamingos create water tornadoes to trap prey
Flamingos feed by dragging their flattened beaks forward along the shallow lake bottom. To improve the efficiency of feeding, they stomp the dance to unravel the bottom, create a vortex of excitement with their heads, and constantly slap their beaks to draw food like brine shrimp in their mouths. Credit: Aztli Ortega Flamingos standing calmly in shallow alkaline lakes, may…

Create real-time, high-resolution imaging of reused smartphone camera sensor anti-proton annihilation
A new AEGIS detector (left) and the selection of anti-proton annihilation that it captured (right). Annihilation appears as a star-shaped event with multiple tracks emanating from a single major vertex. Green, cyan, and orange arrows point to examples of nuclear fragments.

Fake Grass? Scientists create a “more ethical” version of French delicateness
A stress test for researchers’ foie gras pate. This is created without the need to supply power. Credit: Thomas A. Birgis Foie gras – the fatty liver of ducks and geese – is French delicateness, paying homage to its rich, buttery flavor. However, its production was banned in some countries, accompanied by the power of animals. Now, a team of…

Light-induced symmetric changes in small crystals allow researchers to create materials with customized properties
An artistic illustration of lead sulfide quantum dots when lead atoms temporarily move to a new position and undergo structural changes when exposed to light. Credit: Cotz Lab, Middlebury College. Imagine building a Lego Tower with perfectly aligned blocks. Each block represents a small crystal atom known as a quantum dot. When you hit a tower, external forces can shift…

Bio-based methods create polyurethanes free of toxic chemicals
Graphical abstract. Credit: Angewandte Chemie International Edition (2025). doi:10.1002/anie.202421540 Diisocyanates are used in the preparation of all polyurethanes, from foam used in soles to thermoplastic science used in the case of mobile phones. Aromatic diisocyanates that give polyurethane foam give it foam of its structure, but are commonly prepared on the megaton scale in very safe facilities, thanks to the…

Intertwined polymers and nanosheets create skin-like self-healing hydrogels
The artistic representation of the moebiusling hydrogel formed by self-healing. Credit: Margot Lepetit / Aalto University We all encounter gels in our daily lives, from the soft, sticky substances we put in your hair to jelly-like components of various food items. Human skin shares gel-like properties, but has unique qualities that are extremely difficult to replicate. It combines high stiffness…

Mars Time Machine: Researchers create a virtual model to decipher the climate evolution of the Red Planet
Credit: CC0 Public Domain Researchers are creating sophisticated simulations that will help you understand Mars’ climate history better and help you determine whether it can once be a life-sustaining experience. An international team of researchers is developing a model of Mars’ evolution that can unlock some of the secrets of many years, including whether they once had life. François, a…
