Gamma-ray laser moves a step closer to reality

A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium.

Probing Question: Are we running out of helium?

Party planners, take note: the atmosphere may become a little deflated at gala events in the future. Some scientists are sounding the alarm about the wastefulness of using helium—a rare, non-renewable gas—to fill party ...

Chiral magnetic effect generates quantum current

Scientists at the U.S Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a new way to generate very low-resistance electric current in a new class of materials. The discovery, ...

Sound-shaping metamaterial invented

A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists.

US Congress acts to avert helium shortage

The US Congress, entrenched in a titanic budget battle, managed to come together Thursday to pass legislation that prevents a market shortage of helium.

Lessons of conventional imaging let scientists see around corners

Along with flying and invisibility, high on the list of every child's aspirational superpowers is the ability to see through or around walls or other visual obstacles. That capability is now a big step closer to reality as ...

Gold nanoparticles for cancer treatment

A new project at the National Physical Laboratory (NPL) will develop methodologies to measure the radio-biological impact of gold nanoparticles, when used in combination with ionising radiation for enhancing radiotherapy ...

High-speed microscope illuminates biology at the speed of life

The Columbia team behind the revolutionary 3-D SCAPE microscope announces today a new version of this high-speed imaging technology. In collaboration with scientists from around the world, they used SCAPE 2.0 to reveal previously ...
