Warning computer hackers shortens their intrusion

(Phys.org) —Cybercrime has grown to define the criminal landscape of the 21st century. Yet, cybersecurity research has focused on the crime – computer system attacks – and on counter measures to it, while largely ignoring ...

Laser-induced damage in focus

The transformation of infrared light to a different wavelength, such as visible light, is important in many applications. Some of the most efficient semiconductor lasers operate in the infrared region of the spectrum, whereas ...

Calculating waiting time at security control

Thermal imaging cameras at airports could calculate queues and check-in times better than systems that make estimates using Bluetooth and WiFi on passengers' mobiles.

NASA video shows GPM's journey to Japan

(Phys.org) —Pack it up, put it on a plane and fly it to Japan. It sounds simple enough, but a new video from NASA shows when your package is a satellite, it's anything but.

Engineer designs digital solution for pesticide drift

(Phys.org) —It's a problem that plagues farmers and haunts environmentalists: how to reduce pesticide applications and ensure they are used most effectively. A Cornell engineer has come up with a novel, high-tech solution, ...

Chance determines cell death or normal sugar consumption

Some cells fail by chance, and not due to a genetic defect, to properly initiate the molecular processes for the breakdown of sugar. These cells are unable to grow and subsequently die. This discovery was done by a multidisciplinary ...
