Laser &Photonics Reviews, EarlyView.Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

Performance and loads data from an outdoor hover test of a Lynx tail rotor [PDF]
A Lynx tail rotor was tested in hover at the Outdoor Aerodynamic Research Facility at NASA Ames Research Center. The test objectives were to measure the isolated rotor performance to provide a baseline for subsequent testing, and to operate the rotor ...

Aerodynamic Effect of Strakes on Two-Dimensional Tail Boom Models of the OH-58A and the OH-58D Helicopters [PDF]
During hover and low speed flight, helicopters experience significant aerodynamic forces on the tail boom caused by the wake from the main and tail rotors and by crosswinds.

Research advances in the applications of mitochondria‐targeted cyanine dyes in imaging
VIEW, EarlyView.Near‐infrared (NIR) fluorescence imaging, a novel non‐invasive diagnostic tool, plays a crucial role in the imaging and monitoring of solid tumors. At its core are NIR fluorescent dyes, which are widely utilized due to their ability to minimize tissue autofluorescence interference, thereby significantly enhancing the signal‐to‐noise ratio (SNR) and ...

Wildlife Biology, EarlyView.Drones are used to monitor bird nesting sites at less accessible locations, such as on cliffs, human infrastructure, or within the tree canopy. While there are a growing number of studies documenting avian behavioral responses to various drones, there is a continued need to monitor taxa‐specific responses to different drone models. We explored both the

Wildlife Biology, EarlyView.Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.
