Tweezers of sound can pick objects up without physical contact

Hemispherical array of ultrasound transducers lifts objects off reflective surfaces

27-Jul-2021

Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a small polystyrene ...

A novel microscope pins down the miracle of molecular oxygen

Researchers track the first step of the reaction of one single dye pigment with oxygen at unprecedented resolution

26-Jul-2021

Why is it that the colours of a t-shirt fade over time in the sun? Why do you get a sunburn, and why do the leaves of a tree turn brown in the autumn? These questions all have one theme in common, the interplay between dye pigments and ambient oxygen. Every child learns about this chemical ...

How ethane-consuming archaea pick up their favorite dish

Scientists sucessfully decoded the structure of the enzyme responsible for ethane fixation

09-Jul-2021

Hot vents in the deep sea are home to microbes that feed on ethane. They were discovered recently from scientists of the Max Planck Institute for Marine Microbiology. Now the researchers from Bremen succeeded in finding an important component in the microbial conversion of the gas. They were able ...
