ISOLDE steps into unexplored region of the nuclear chart to study exotic isotopes

Many heavy elements, such as gold, are thought to form in cosmic environments rich in neutrons—think supernovae or mergers of neutron stars. In these extreme settings, atomic nuclei can rapidly capture neutrons and become heavier, creating new elements. At the far reaches of the nuclear chart, which arranges all known nuclei according to their number of protons and neutrons, lie unexplored nuclei that are crucial to understanding the details of this rapid neutron-capture process. This is especially the case for nuclei with fewer than 82 protons and more than 126 neutrons.

Ultrasound can selectively kill cancer cells

A new technique could offer a targeted approach to fighting cancer: low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed.

Uranus and Neptune's Differences May Come from Collisions, Finds New Study

Giant impacts could explain the many differences between the ice giants of our solar system, computer simulations show.

What Would the Sun Sound Like If We Could Hear It On Earth?

A thought experiment explores the awesome power of our star.

Lasers etch a 'perfect' solar energy absorber

Researchers demonstrate how laser etching of metallic surfaces creates the ''perfect solar energy absorber.'' This not only enhances energy absorption from sunlight, but also reduces heat dissipation at other wavelengths. The researchers also demonstrate solar energy harnessing with a thermal electric generator.

Researchers discover method to detect motor-related brain activity

Motor-related brain activity, particularly its accurate detection, quantification and classification capabilities, is of great interest to researchers. They are searching for a better way to help patients with cognitive or motor impairments or to improve neurorehabilitation for patients with nervous system injuries.

Sand dunes can 'communicate' with each other

Even though they are inanimate objects, sand dunes can 'communicate' with each other. A team from the University of Cambridge has found that as they move, sand dunes interact with and repel their downstream neighbours.

New quantum switch turns metals into insulators

Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick and how securely our money is stored in the bank.

Making high-temperature superconductivity disappear to understand its origin

Purely electronic interactions could be behind copper-oxygen compounds conducting electricity without resistance at relatively high temperatures.

New quantum switch turns metals into insulators

Researchers have demonstrated an entirely new way to precisely control electrical currents by leveraging the interaction between an electron's spin and its orbital rotation around the nucleus.
