Radar

Saab's new Ultra-Lightweight Camouflage Screen not only lets soldiers blend into the foliage and blocks infrared to foil heat seeking sensors, but it also hides them from radar sweeps, while still letting them receive GPS signals and radio communications.

In an effort to foil these proficient hide-and-seekers, scientists have enlisted a tech secret weapon to find the northern hairy-nosed wombat, a shy and critically endangered Aussie icon. Despite their hiding skills, just an estimated 315 animals remain.

In a dramatic bit of improvisation, NASA' Jet Propulsion Laboratory (JPL) in Pasadena, California, has managed to reestablish communications with the Voyager 2 spacecraft 12.3 billion miles (19.9 billion km) from Earth after losing contact on July 21.

A WWII bunker in England has been transformed into a remarkable vacation home. UK studio Corstorphine & Wright worked to retain the original character of the bunker while adding a "bomb blast" glazed opening to provide superb views of the coastline.

Researchers have created a device that uses photonic radar to remotely and accurately monitor breathing, even distinguishing between more than one patient. The device might one day be used in hospitals, aged care facilities, prisons, and at home.

There are now a number of ebikes equipped with radar systems which warn riders of vehicles approaching from behind. If your bike isn't among those, you can now change that by slapping on Garmin's Varia eRTL615 radar/tail light module.

After decades of speculation, astronomers have discovered the first direct evidence of volcanic activity on Venus. Radar images of Earth’s “twin” taken just a few months apart reveal a recent eruption.

Despite making up 85% of the total mass in the universe, dark matter eludes detection. A new study proposes a unique way to look for it using the Earth’s atmosphere as a giant detector for dark matter particles streaming through the air like meteors.

New evidence has emerged in the debate about whether there’s liquid water on Mars. In a study led by the University of Cambridge, scientists examined the topology of Martian ice sheets and found signatures that match subglacial lakes here on Earth.

It was seven years ago that we first heard about Garmin's Varia Radar tail light, which warns cyclists of vehicles approaching from behind. After adding smartphone compatibility in 2020, Garmin has now put a camera in the device.

A new type of radar can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth signals, enabling radar that can detect smaller objects, and even monitor patient vital signs in hospitals.

Recent studies reported the discovery of lakes of liquid water below the polar ice caps on Mars, but others later refuted the find. Fueling the debate are two new independent studies, which have reached opposite conclusions.
