Host a ’90s-Style Hangout
The Touch Grass Challenge Let’s log off and head outside. Week 4 Before the hangout During the hangout It’s almost summer. Put your phone down. Go outside. I’m in!
Your GPS Lies in Cities. Scientists Finally Fixed It
GPS often struggles in cities because skyscrapers reflect and block satellite signals, leading to inaccurate locations. A new system called SmartNav tackles the problem with advanced corrections and 3D city modeling, delivering near-centimeter-level precision. Credit:…
