Even without a brain, metal-eating robots can still search for food
The “metal-eating” robot can follow a metal path without using a computer or needing a battery.
DraBot: A soft robotic dragonfly that senses and monitors its environment
Electronics-free DraBot uses air pressure, microarchitectures, and self-healing hydrogels to watch for changes in pH, temperature, and the presence of contaminants.
Is the UK’s Forensic Regulator role fit for purpose?
The demands of quality forensic science demonstrate the impact of regulatory activities and external factors on the work of forensic science providers.
A spotlight on robots helps them turn “feeling” into movement
Researchers recreate the somatic nervous system in robots, allowing them to convert feeling into movement under different stimuli.
Overcoming electrical current leaks in modern memory devices
A new device significantly decreases unwanted current leakage from memory devices, which could help reduce the greenhouse gas emissions of future data centers.
New approach keeps outdoor wearable electronics cool
“Cool gadgets” takes on new meaning as scientists develop a radiative cooler that keeps wearable device temperature down, even under direct sunlight.
Temporary light-emitting tattoos, anyone?
A new fabrication method allows researchers to create ultra-thin OLED materials that can be applied to the skin using temporary tattoo paper.
Fluorescent nanodiamonds successfully injected into living cells
Fluorescent nano-sized diamonds give a better glimpse inside cells.
