If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.

Listening to music could reduce the dizziness, nausea and headaches virtual reality users might experience after using digital devices, research suggests. Cybersickness -- a type of motion sickness from virtual reality experiences such as computer games -- significantly reduces when joyful music is part of the immersive experience, the study found. The intensity of the nausea-related symptoms of cybersickness was also found to substantially decrease with both joyful and calming music.

Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.

Engineers have shown that by using an ingestible capsule that delivers an electrical current to the cells they can stimulate the release of the hormone ghrelin. This approach could prove useful for treating diseases that involve nausea or loss of appetite, such as anorexia or cachexia.

Researchers developed a proof of concept for a superconducting highway that could transport vehicles and electricity, cooling the necessary superconductors with a pipeline of liquid hydrogen. Most magnetic levitation designs feature the superconductor inside the vehicle, which is suspended above a magnetic track. The authors decided to flip that arrangement upside down, putting the superconductor on the ground and giving each vehicle a magnet. The result is a system with multiple uses, placing it within the realm of affordability.
