Researchers at the University of York have shown that a new quantum-based procedure for distributing secure information along communication lines could be successful in preventing serious security breaches.

An international group of researchers, involving scientists from Universidad Carlos III de Madrid (UC3M) and the Complexity Science Hub Vienna, developed a tool to track and analyze gender inequality through Facebook usage data.

From the spatter analysis made famous in the TV show Dexter to the frequent DNA profiling of CSI and the real cases covered in the FBI Files, blood tests are ubiquitous in forensic science.
