Avoiding drones' prying eyes can be as complicated as donning a high-tech hoodie and as simple as ducking under a tree.
Mating laser-driven atomic clocks like the one shown here with microwaves promises more accurate electronic devices.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.

Releasing balloons at weddings and other celebrations is festive, until they break into pieces and become plastic pollution. A citizen science project is spotlighting the problem.
It’s not all about the cost of treatment – and this is something the next government will need to address.
Where to land?
Putting driverless cars on the road safely is hard enough. Doing it in the air is much more difficult.
The orientations of the stone walls that crisscross the Northeastern U.S. can tell a geomagnetic tale as well as a historical one.
Scientific inspiration struck a geologist after many walks through the woods in New York and New England. These ruins hold the secret of where the compass pointed north when they were built centuries ago.
What does your phone know about you?
Every device that you use, every company you do business with, every online account you create – they all collect data about you and analyze it to figure out minute details of your life.
Which is the right map for you?
If you want to really learn your way around a new place, paper maps still trump digital options.
Amelia Earhart’s Lockheed Model 10-E Electra, with advanced navigation equipment mounted above the cockpit.
Eight decades after missing aviator Amelia Earhart was declared dead, technologies still don't quite track every airplane all over the globe.
Starting new conversations.
As part of a new strategy to combat loneliness GPs will be able to prescribe social activities. But is this ethical?
Wait – where am I?
Without their devices, regular GPS users take longer to negotiate a route, travel more slowly and make larger navigational errors.
Safety cards that allow victims to press a button to alert a 24/7 call centre have proved successful in protecting victims from further abuse.

We shouldn’t be telling victims of domestic violence to stop using technology. We should encourage them to use their digital devices to share their stories and seek the help they deserve.
The shipping industry has been slow to prepare adequate cybersecurity.
Cyber vulnerabilities in shipping show how far the industry has to go. But proper cyber security of ships is more complex than you might initially think.
British space firms would get a shot in the arm from building a new GPS-style system if the UK is shut out of the EU's programme.
Andy Thomas is one of the few Australian-born applicants who has became an astronaut. Will there be more with an Australian space agency?
$41M over four years is about the minimum viable amount to start towards important goals for an Australian space agency.

The wired Earth of the 21st century is at the mercy of the volatile nature of the sun.
Nothing to stop high energy weapons being deployed in orbit around Earth.
Australia is playing a major role in developing legal guidelines that would govern how any war in space is played out. The authors of MILAMOS hope the manual is never actually required.
It feels like we've seen less progress on charge time than almost anything else in smartphones. Could software efficiency be the answer?
London's Gatwick Airport has installed thousands of virtual beacons to help passengers navigate when GPS won't work inside.
Scientists use satellite sensing to find the Earth’s centre of mass.
Driverless cars and drones will require pinpoint location accuracy, which means our methods for measuring the Earth's centre need an overhaul.
