Breakthrough discovery sheds light on heart and muscle health      (via sciencedaily.com)     Original source 

The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where thick and thin protein-filaments interact within the sarcomere, the fundamental building block of both skeletal and heart muscle cells. Any alterations in thick filament proteins can have severe consequences for our health, leading to conditions such as hypertrophic cardiomyopathy and various other heart and muscle diseases.

How to protect biocatalysts from oxygen      (via sciencedaily.com)     Original source 

There are high hopes for hydrogen as the key to the energy transition. A specific enzyme group found in algae and in bacteria can produce molecular hydrogen simply by catalyzing protons and electrons. However, the enzyme group is so sensitive to oxygen that commercial use of the hydrogen produced by this process as a green energy source is not yet possible. Researchers have now increased the oxygen stability of a hydrogen-producing enzyme by genetically generated channel blockages.

DNA Origami nanoturbine sets new horizon for nanomotors      (via sciencedaily.com)     Original source 

Researchers introduce a pioneering breakthrough in the world of nanomotors -- the DNA origami nanoturbine. This nanoscale device could represent a paradigm shift, harnessing power from ion gradients or electrical potential across a solid-state nanopore to drive the turbine into mechanical rotations. The core of this pioneering discovery is the design, construction, and driven motion of a 'DNA origami' turbine, which features three chiral blades, all within a minuscule 25-nanometer frame, operating in a solid-state nanopore. By ingeniously designing two chiral turbines, researchers now have the capability to dictate the direction of rotation, clockwise or anticlockwise.

Simulating cold sensation without actual cooling      (via sciencedaily.com)     Original source 

The perception of persistent thermal sensations, such as changes in temperature, tends to gradually diminish in intensity as our bodies become accustomed to the temperature. This phenomenon leads to a shift in our perception of temperature when transitioning between different scenes in a virtual environment. Researchers have now developed a technology to generate a virtual cold sensation via a non-contact method without physically altering the skin temperature.
