Drones help calibrate radio telescope at Brookhaven Lab

Cosmologists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are experimenting with a prototype radio telescope, called the Baryon Mapping Experiment (BMX). Built at the Lab in 2017, the prototype ...

GPS helping provide more precise precipitation predictions

Scientists are using GPS signals to measure air moisture for better weather forecasting. The method is now being incorporated into the Bureau of Meteorology's weather forecast models following successful tests over Australia, ...

NASA small satellites can aid hurricane forecasts with GPS

Eight briefcase-size satellites flying in a row may be key to improving forecasts of a hurricane's wind speed—detecting whether it will make landfall as a Category 1 or a Category 5. NASA's Cyclone Global Navigation Satellite ...

Satellites assisting look into hurricanes

A mission to probe winds deep inside hurricanes, where most satellites cannot see and few aircraft venture, is showing signs of success despite an unexpected obstacle linked to tensions in the Middle East.

Every bat travels differently

The females of some bat species migrate hundreds of kilometers after hibernation to give birth to their offspring in insect-rich regions. Unlike birds, it is largely unknown how bats keep their energy consumption low during ...

Otago-led research set to make smartphones even smarter

The accuracy of the global positioning system (GPS) in smartphones has been significantly improved thanks to research conducted at the University of Otago, New Zealand, in collaboration with Curtin University, Australia.

New defenses sought against GPS spoofing attacks

Cyberattacks with the potential to expose sensitive information and cripple basic services could start with what would seem to be the most harmless of computer functions.
