Article Synopsis
- The study focuses on creating high-quality optical resonators, essential for technologies like metrology and quantum optics, particularly aiming to achieve extreme temporal coherence at visible wavelengths.* -
- Researchers developed a new type of etch-free metasurface that minimizes defects, successfully demonstrating an impressive ultrahigh-Q resonance in free space, along with a novel spectroscopy technique for detailed analysis.* -
- By integrating a monolayer material, the team achieved highly unidirectional exciton emission without a power density threshold, showcasing potential applications in optical sensing and controlling quantum light sources.*
Traumatic brain injury represents a significant global health burden and has the highest prevalence among neurological disorders. Even mild traumatic brain injury can induce subtle, long-lasting changes that increase the risk of future neurodegeneration. Importantly, this can be challenging to detect through conventional neurological assessment.

- - The experiment at Lawrence Berkeley National Laboratory aimed to produce a superheavy element with an atomic number of 114 or greater by bombarding an actinide target with a ^{50}Ti beam.
- - Using the Berkeley Gas-filled Separator, researchers successfully isolated and implanted produced Livermorium (Lv) ions into a high-tech detector system, observing two decay chains linked to ^{290}Lv.
- - The measured production cross-section of the process was 0.44 picobarns at a specific energy, marking the first published evidence of superheavy element production near the "island of stability" with this method, paving the way for future discoveries beyond element Z=118.
Traumatic brain injury commonly impairs attention and executive function, and disrupts the large-scale brain networks that support these cognitive functions. Abnormalities of functional connectivity are seen in corticostriatal networks, which are associated with executive dysfunction and damage to neuromodulatory catecholaminergic systems caused by head injury. Methylphenidate, a stimulant medication that increases extracellular dopamine and noradrenaline, can improve cognitive function following TBI.
