Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective methods to measure this exchange of ions, which is kn
First-of-a-kind laser spring opens up new avenues for plasma control
When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated a rotating, spring-shaped laser pulse, opening new pos
Cosmic dust could play key role in cracking long-standing mystery of solar corona heating
A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly influence how energy moves through the solar c
Bacterial protein reveals a hidden rule for controlling calcium
A small change in acidity can transform the world around us. A squeeze of lemon changes the taste of food. Vinegar preserves vegetables. Stomach acid helps break down a meal. These familiar effects come from protons—tiny charged particles that can reshape chemical interactions.
Evidence of elusive high-energy gravitons in quantum Hall systems
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a phenomenon that emerges when electrons are confined to a ve
Medieval plague survivors left us graffiti, court records and a lesson for COVID

And what can you do if you’re charged thousands for a quick, easy job?Sarah was alone in her flat with her three-month-old baby when a man put a card machine in her face and demanded she pay £2,209. A few hours earlier Sarah, 30, had been for a walk with her daughter when it dawned on her that she had left her keys at home. She d
