New 'all-optical' nanoscale sensors of force access previously unreachable environments Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution is needed for a wide range of applications, from robotics to cellular biophysics and medicine and even to space travel. Nanoscale luminescent force sensors excel at measuring piconewton forces, while larger sensors have proven powerful in probing micronewton forces.

A tour de force: Engineers discover new 'all-optical' nanoscale sensors of force Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' nanosensors are probed with light only and therefore allow for fully remote read-outs -- no wires or connections are needed.

Stanford’s Vaccine Breakthrough Boosts Flu Protection Like Never Before Stanford Medicine researchers have developed a new method for influenza vaccination that encourages a robust immune response to all four common flu subtypes, potentially increasing the vaccine’s efficacy. In laboratory tests using human tonsil organoids, the modified vaccine showed promising results in combating both seasonal and bird flu strains. The approach involves a combined [...]
