It was in the oceans that life first evolved and where complex animals have thrived for over 600 million years. Marine animals survive in environments as diverse as tropical coral reefs, polar ice-capped oceans, and the lightless abyssal depths, says…
Police agencies are using facial and object recognition technology for counterterrorism operations. Video footage played a key role in finding the culprits responsible for the November 2015 Paris attacks, with a CCTV video at Brussels airport used to pin down…
Currently, the most widely used technology to detect underwater objects is sound navigation and ranging (SONAR), because acoustic waves can penetrate the water depths to the bottom of the sea. SONAR also suffers from unwanted multipass echoes that are due…
The phonon is the physical particle representing mechanical vibration and is responsible for the transmission of everyday sound and heat. Understanding and controlling the phononic properties of materials provides opportunities to thermally insulate buildings, reduce environmental noise, transform waste heat…
In the wake of increasing electronic gadget sales, the overheating problem for battery chargers has become an increasingly common safety issue. Overheating of chargers certainly can be caused by substandard chargers, faulty batteries, or by misuse of the chargers. In…
The U.S. Navy and DARPA ran a facility–the High Frequency Active Auroral Research Program (HAARP) in Gakona, Alaska—before it was passed to the University of Alaska in 2014. HAARP was a research program to study ionosphere and its response to…
A global race has ensued to exploit and operationalize quantum technologies for the use of military effects. Quantum information science (QIS), field comprises four domains: Quantum Communication, where individual or entangled photons are used to transmit data in a provably…
Although the hardware and software technology for fully autonomous cars is ready today, the cars themselves may still be a decade or more away, vehicle experts said at the recent North American International Auto Show in Detroit. The challenge for…
GPS hacking and spoofing have made headlines around the world in recent years, from researchers successfully hacking a yacht’s navigation to bring it off its programmed course to the discovery of dozens of Russian ships whose GPS signals indicated they…
Organic semiconductors enable the fabrication of a range of lightweight and mechanically flexible optoelectronic devices. Organic LEDs, solar cells, and field-effect transistors are now routinely made in bendable or even stretchable formats and with extremely low specific weights. Most…
