Using Sound To Control Enzymatic Reactions
Unhackneyed compartmentalization generated by audible sound allows the enzyme reactions to be controlled spatiotemporally. Spatiotemporal regulation of multistep enzyme reactions through compartmentalization is essential in…
Introducing the MIT Oreometer – Mechanical Engineers Put an Oreo’s Cream Filling Through a Battery of Tests
Mechanical engineers put an Oreo’s cream filling through a battery of tests to understand what happens when two wafers are twisted apart. When you twist…
Simulations Reveal Fundamental Insights on Janus Particles
Interfacial diffusion of nanoparticles strongly affected by their shape and surface coating. Named for a Roman god, Janus particles refer to nanoparticles that possess surfaces…
Owl Wing Design With Serrated Edges Reduces Aircraft, Wind Turbine Noise Pollution
Serrated edge of owl wings makes them quieter than other birds, can help inform airfoil designs. Trailing-edge noise is the dominant source of sound from…
Using Ice To Boil Water: Heat Transfer Discovery Expands on 18th Century Physics Principle

Why Teapots Always Drip – Scientists Finally Explain the “Teapot Effect”
Scientists at TU Wien answer an age-old question: How can the so-called “teapot effect” be explained? The “teapot effect” has been threatening spotless white tablecloths…
Six Foot COVID-19 Rule Is “Arbitrary” – Social Distancing Is Not Effective Mitigation on Its Own
A new study has shown that the airborne transmission of COVID-19 is highly random and suggests that the two-meter (6 foot) rule was a number…
Fractured Artificial Rock Helps Crack a Strange 54-Year-Old Fluid Mystery
Princeton researchers have solved a 54-year-old puzzle about why certain fluids strangely slow down under pressure when flowing through porous materials, such as soils and…
Fluid Dynamics Shows Why You Should Wear Masks Outdoors To Prevent Coronavirus Exposure
Wind blowing in the same direction as a cough can increase viral transmission. As the highly infectious delta variant of the coronavirus continues to spread…
Unified Physics Theory Explains How Materials Transform From Solids to Liquids
Years of meticulous experimentation have paid off for researchers aiming to unify the physics that defines materials that transition from solids to liquids. The researchers…
Droplets Loaded With Coronaviruses Last Far Longer Than Previously Thought
Experiments with dummy heads and masks. Credit: TU Wien Tiny droplets loaded with viruses disappear more slowly after exhalation than previous models suggested. Experiments and…
COVID Aerosol Filtration: Nanofiber Face Masks Improve Efficiency, Need Replacing More Often
Videos capture nanofiber behavior under water aerosol exposure. Since its outbreak, the COVID-19 virus has infected more than 220.9 million people worldwide and has claimed…
Injecting Drugs Without Needles: High-Speed Camera Captures a Water Jet’s Splashy Impact As It Pierces a Droplet
The results may help engineers develop a way to inject drugs without needles. Squirting a jet of water through a drop of liquid may sound…
Dangerous Oscillations in Rocket Engines Driven by Fuel Flow and Heat Fluctuations
Power source clusters near rocket engine fuel injectors could create combustion oscillations. Combustion engines can develop high-frequency oscillations, leading to structural damage to the engines…
Solving The Mystery of the Pointy Droplets
A certain type of oil droplets changes shape when cooled and shrunk: from spherical through icosahedral to flat hexagonal. Two competing theories couldn’t fully explain…
Smashing the COVID Curve: Little Differences in Behavior Decide Between Success and Complete Failure
