Luis Alarcon-Martinez, Adriana Di Polo and Deborah Villafranca-Baughman Researchers at the CRCHUM find a new structure by which cells in the retina communicate with each other, regulating blood supply to...

Wei Gao's triboelectric generator is made of commonly available commercial materials and creates electricity when the wearer moves. Courtesey: Caltech. The advent of inexpensive wearable sensors that can monitor heart...

The ocean floor and the ground beneath our feet are riddled with tiny nanowires—1/100,000th the width of a human hair—created by billions of bacteria that can generate electric currents from...

The human brain efficiently executes highly sophisticated tasks, such as image and speech recognition, with an exceptionally lower energy budget than today’s computers can. The development of energy-efficient and tunable...

Researchers at Sandia National Laboratories have developed an array of processors coated with titanium oxide that has the potential to revolutionize technologies like voice recognition, image processing and autonomous driving....

False-colored scanning electron microscope images of the device, general view (left), and zoom-in on the nano-ram (right). The platform is 1.5 µm wide and 3 µm long, with 80 ×...

Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays,...

Scientists have revealed how nanomaterials inspired by insect wings are able to destroy bacteria on contact. The wings of cicadas and dragonflies are natural bacteria killers, a phenomenon that has...

A multidisciplinary group that studies the physical and chemical properties of insect wings has demonstrated the ability to reproduce the nanostructures that help cicada wings repel water and prevent bacteria...

The prototype device non-invasively detects COVID-19 in the exhaled breath of infected patients, similar to a breathalyzer test for alcohol intoxication. Few people who have undergone nasopharyngeal swabs for coronavirus...
