Phys.org / Physicists' laser experiment excites atom's nucleus, may enable new type of atomic clock
For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be replaced with a nuclear ...
Phys.org / Dual-laser approach could lower cost of high-resolution 3D printing
Researchers have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing process less expensive, helping it find wider ...
Medical Xpress / Cracking the code for cerebellar movement disorders
The cerebellum is a region of the brain that helps us refine our movements and learn new motor skills. Patients and mouse models experience many kinds of abnormal movements when their cerebellum is damaged. They can have ...
Phys.org / True scale of carbon impact from long-distance travel revealed
The reality of the climate impact of long-distance passenger travel has been revealed in new research from the University of Leeds.
Phys.org / Small change in Earth's oxygen levels may have sparked huge evolutionary leap
New research provides the clearest evidence yet that the Cambrian explosion—a rapid burst of evolution 540 million years ago, could have been triggered by only a small increase in oxygen levels in Earth's atmosphere and ...
Phys.org / Novel method enhances size-controlled production of luminescent quantum dots
Luminescence refers to the result of a process in which an object absorbs light at one wavelength and then re-emits it at another wavelength. Through light absorption, electrons in the ground state of the material are excited ...
Phys.org / Harmful substances in soft plastic lures: Risks for anglers and the environment
An interdisciplinary research team has demonstrated in their new study that harmful phthalates and endocrine disruptors are released from common soft plastic baits.
Phys.org / Study examines online intimidation targeting state election administrators
In the lead-up to the 2022 U.S. midterm elections, Arizona's chief election officer Katie Hobbs received far more harassing messages on Twitter than any of her counterparts in other states. More than 30% of all tweets directed ...
Tech Xplore / New thermodynamics method enhances maintenance and prevents failures in engineering systems
The performance and reliability of machines and devices reduce as they age. Currently, inaccurate degradation characterization leads to over- and under-maintenance, both of which have dire consequences on society. Hence, ...
Phys.org / Study claims governments should account for public attitudes before communicating crisis policies
Research published in the International Journal of Knowledge-Based Development has found that our feelings and attitudes during times of crises affect our behavior and that during globally testing times, such as the COVID-19 ...
Phys.org / It's a challenging drive to Washington's ocean beaches as state spends billions to help fish
It took 50 million years for salmon to evolve and only about 50 years to nearly wipe them out. Now, Washington's native salmon and steelhead populations are getting a reprieve—one stream at a time.
Tech Xplore / Microsoft will pay $14M to settle allegations it discriminated against employees who took leave
Microsoft Corp. has agreed to pay $14.4 million to settle allegations that the global software giant retaliated and discriminated against employees who took protected leave, including parental and disability, the California ...
