One step closer to a clock that could replace GPS and Galileo

Scientists have made a breakthrough to a crucial element of an atomic clock -- devices which could reduce our reliance on satellite mapping in the future -- using cutting-edge laser beam technology.

Novel technology aims to improve lithium metal battery life, safety

Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to researchers.

Quantum physicists succeed in controlling energy losses and shifts

In a new study, scientists demonstrate that they can increase the dissipation rate, on demand, by a factor of thousand in a high-quality superconducting resonator -- just like the ones used in prototype quantum computers.

Ultrathin and ultrafast: Scientists pioneer new technique for two-dimensional material analysis

Using a never-before-seen technique, scientists have found a new way to use some of the world's most powerful X-rays to uncover how atoms move in a single atomic sheet in real time, opening up new possibilities for probing two-dimensional materials.

Researchers turn liquid metal into a plasma

Researchers have found a way to turn a liquid metal into a plasma and to observe the temperature where a liquid under high-density conditions crosses over to a plasma state. Their observations have implications for better understanding stars and planets and could aid in the realization of controlled nuclear fusion -- a promising alternative energy source whose realization has eluded scientists for decades.

Physicists solve a beta-decay puzzle with advanced nuclear models

An international collaboration including scientists at the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) solved a 50-year-old puzzle that explains why beta decays of atomic nuclei are slower than what is expected based on the beta decays of free neutrons.

New way to sense earthquakes could help improve early warning systems

Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell the difference between life and death. Researchers demonstrate a new earthquake detection method -- their technique exploits subtle telltale gravitational signals traveling ahead of the tremors. Future research could boost early warning systems.

Listening to quantum radio

Researchers have created a quantum circuit that enables them to listen to the weakest radio signal allowed by quantum mechanics. This new quantum circuit opens the door to possible future applications in areas such as radio astronomy and medicine (MRI). It also enables researchers to do experiments that can shed light on the interplay between quantum mechanics and gravity.

New method opens the way for cutting tools with longer lifetime

Researchers have developed a theoretical model that enables simulations for showing what happens in hard cutting materials as they degrade. The model will enable manufacturing industry to save both time and money.

Investigating the motility of swimming Euglena

Some species of Euglenids, a diversified family of aquatic unicellular organisms, can perform large-amplitude, elegantly coordinated body deformations. Although this behavior has been known for centuries, its function is still highly debated.
