How mice block out the sound of their own feet
A mouse's brain has a built-in noise-cancelling circuit to ensure that the mouse hears the sounds of an approaching cat better than it hears the sounds of its own footsteps, according to new research. It's a direct connection from the motor cortex of the brain to the auditory cortex that says essentially, "we're running now, pay no attention to the sound of my footsteps." "What's special about th

A tailless aerial robotic flapper reveals that flies use torque coupling in rapid banked turns
Insects are among the most agile natural flyers. Hypotheses on their flight control cannot always be validated by experiments with animals or tethered robots. To this end, we developed a programmable and agile autonomous free-flying robot controlled through bio-inspired motion changes of its flapping wings. Despite being 55 times the size of a fruit fly, the robot can accurately mimic the rapid e

Organic and solution-processed tandem solar cells with 17.3% efficiency
Although organic photovoltaic (OPV) cells have many advantages, their performance still lags far behind that of other photovoltaic platforms. A fundamental reason for their low performance is the low charge mobility of organic materials, leading to a limit on the active-layer thickness and efficient light absorption. In this work, guided by a semi-empirical model analysis and using the tandem cel

We report a designed heteronuclear heme-[4Fe-4S] cofactor in cytochrome c peroxidase as a structural and functional model of the en

Quantum entanglement of the spin and orbital angular momentum of photons using metamaterials
Metamaterials constructed from deep subwavelength building blocks have been used to demonstrate phenomena ranging from negative refractive index and -near-zero to cloaking, emulations of general relativity, and superresolution imaging.

Glutamate triggers long-distance, calcium-based plant defense signaling
Animals require rapid, long-range molecular signaling networks to integrate sensing and response throughout their bodies.

Similarly, plants sense local signals, such as herbivore attack, and transmit t
