SUMMARYResearchers have found that using multiple patterns to unlock an Android phone provides significantly more security than the current single-pattern method, and, in some cases, may be more secure than the 4- and 6-digit PIN unlocking method commonly used on…
Engineers have invented a way to spray extremely thin wires made of a plant-based material that could be used in N95 mask filters, devices that harvest energy for electricity, and potentially the creation of human organs. The method involves spraying methylcellulose, a renewable plastic material derived from plant cellulose, on 3D-printed and other objects ranging from electronics to plants, according to a Rutgers-led study in the journal Materials Horizons.
Feelings of panic when a person is away from their smartphone could be connected to general feelings of inadequacy and inferiority, a new study of young people in Portugal suggests.
Smartphone owners who unlock their devices with knock codes aren’t as safe as they think, according to new research.
Using electronic devices for too long can cause them to overheat. Now, researchers reporting in ACS’ Nano Letters have developed a hydrogel that can both cool down electronics, such as cell phone batteries, and convert their waste heat into electricity.
