When chiral gold nanoparticles are irradiated with near-infrared femtosecond pulses, visible emission of luminescence is observed. In a study published in Advanced Optical Materials, this luminescence was found to yield high selectivity for left- or right-handed circularly polarized light, depending on the chirality of the nanoparticles, with a dissymmetry factor of approximately 0.7. This finding…

The length of telomeres that protect the ends of our chromosomes should be tightly regulated. Those that are too long predispose to cancer, and those that are too short lose their protective ability, resulting in telomere disorders with serious health consequences. The length of telomeres that protect the ends of our chromosomes should be tightly regulated….
California is one step closer to building its largest water storage facility in nearly 50 years, after a court ruled in favor of the Sites Reservoir project following a challenge by environmental groups.

Ice shelves surrounding Antarctica have been melting with increasing speed in recent years. Much of this melting happens from below, as warm water eats away at their bases. This warm water is moved around Antarctica by currents that remain only partially understood because of the continent’s vastness and remoteness. Mapping these currents in better detail…

California relies on its rivers and streams for a plethora of services—water supply, flood control, biodiversity conservation, and hydropower generation, to name a few. As a result, understanding the flow of water through the state’s stream network is critical for supporting California’s economy and ecosystems.
