Hard times ahead for hackers -- ScienceDaily

Whenever we need to communicate in secret, a cryptographic key is needed. For this key to work, it must consist of numbers chosen at random without any structure — just the opposite of using the birthdate of our favourite pet. But, for a human, it is extremely difficult to choose...

Methylene blue improved physical, biochemical and genetic aging markers in experiments with human skin cells and simulated skin tissues -- ScienceDaily

New work from the University of Maryland suggests that a common, inexpensive and safe chemical could slow the aging of human skin. The researchers found evidence that the chemical — an antioxidant called methylene blue — could slow or reverse several well-known signs of aging when...

Chemical coatings boss around bacteria, in the bugs' own language -- ScienceDaily

Princeton researchers have developed a way to place onto surfaces special coatings that chemically “communicate” with bacteria, telling them what to do. The coatings, which could be useful in inhibiting or promoting bacterial growth as needed, possess this controlling power over...

International team of researchers uncovered the system inside cars' onboard computers -- ScienceDaily

An international team of researchers has uncovered the mechanism that allowed Volkswagen to circumvent U.S. and European emission tests over at least six years before the Environmental Protection Agency put the company on notice in 2015 for violating the Clean Air Act. During a year-long...

Harnessing energy from glass walls -- ScienceDaily

A Korean research team has developed semi-transparent perovskite solar cells that could be great candidates for solar windows.

Scientists are exploring ways to develop transparent or semi-transparent solar cells as a substitute for glass walls in modern buildings with the aim of harnessing...
