Raise your hand if you’ve ever been groped by the TSA. A team of researchers claim that ordinary Wi-Fi can detect weapons and explosives, and maybe it could replace TSA body searches.

The team behind the research tested 15 types of objects and six types of bags. The wi-fi system had success rates of 99% for recognizing dangerous objects, 98% for metal and 95% for liquids. When objects were wrapped inside bags, the accuracy rate dropped to about 90%. The system works by analyzing what happens when wireless signals penetrate and bounce off objects and materials.

In France, the right to disconnect from work has been solidified into law. In the El Khomri law, every employee contract must include a negotiation of obligations required of an employee regarding how connected they are outside of office hours.

A new study has found you may be suffering from excessive stress and anxiety about work expectations even if you don’t actively check work emails in your off-hours. The mere expectation of being in contact 24/7 is enough to increase strain for employees and their families, the new research suggests. In today’s ultra-connected world, with many people often getting work emails sent to their smartphones, a growing number of countries and companies are endorsing “right to disconnect” laws, recreating a much-needed boundary between work and home.
