Making high-quality crystals that resonate strongly with infrared light
Combining electronics with infrared light can enable small, fast, and sensitive devices for sensing, imaging, and signaling at the molecular level. However, in the infrared spectrum, materials must meet strict quality requirements for their crystals.....»»
Agronomists find green way to mitigate the effects of soil salinity
Most crops are sensitive to soil salinity. Excess salts cause salt stress—plants lack water, photosynthesis is suppressed, respiration worsens, chlorophyll breaks down, and potassium ions leak. Water-soluble toxic salts stimulate the synthesis of r.....»»
Workplace tensions: How and when bystanders can make a difference
In today's climate of global political tensions and polarization, workplaces are filled with conflicting viewpoints. When employees hold political identities and perspectives that do not align with their co-workers, they perceive greater incivility f.....»»
Interacting polarons: Physicists simulate interacting quasiparticles in ultracold quantum gas
An electron moving through a solid generates a polarization in its environment due to its electric charge. In his theoretical considerations, the Russian physicist Lev Landau extended the description of such particles by their interaction with the en.....»»
iLeakage flaw could force iPhones and Macs to divulge passwords and more
A vulnerability in A-series and M-series chips could force iPhones, Macs, and iPads to divulge passwords and other sensitive information to an attacker. Security researchers have dubbed the flaw – which affects Safari on the Mac, and any browser on.....»»
