A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
A look into cloudy liquids: New method makes the expansion of turbid drops in water visible
When driving though a bank of fog, car headlights are only of limited help as the light is scattered by the water particles suspended in the air. The situation is similar when you try to observe the inside of a drop of milk in water or the internal s.....»»
Visible light energy yields two-for-one deal when added to carbon dioxide recycling process
By combining visible light and electrochemistry, researchers have enhanced the conversion of carbon dioxide into valuable products and stumbled upon a surprising discovery. The team found that visible light significantly improved an important chemica.....»»
More efficient phenotypic screening method can simultaneously test multiple drugs
Some of the most widely used drugs today, including penicillin, were discovered through a process called phenotypic screening. Using this method, scientists are essentially throwing drugs at a problem—for example, when attempting to stop bacterial.....»»
How images of knives intended to stop youth knife crime may actually be making things worse
You'd be forgiven for thinking that young people are behind most knife crime in the UK. Media coverage often focuses on youth involvement, and the government's plan to halve knife crime focuses specifically on young people and vulnerable teenagers......»»
