Traditionally, long-wave infrared detectors have been costly, gallium arsenide- or indium phosphide-based detectors found in night vision cameras. While cheaper and easier to produce in volume, CMOS technology suffered from the so-called ‘THz gap’ or ‘far-infrared gap’ of the electromagnetic spectrum, unable to detect these long wavelengths. Today, an intriguing solution is becoming available in the form of a THz range CMOS detector for cost-effective, long-wave infrared … Read More

Scientists at the Brookhaven National Laboratory have published a study in which they demonstrate a new color-shifting strategy for lasers that uses interactions between the laser and the chemical bonds of materials called “ionic liquids.” This new method is simple, efficient, and highly customizable, and can change the color of laser light while retaining other important properties of the laser beam. Learn more about this groundbreaking method, its applications and how it could change the world … Read More
Scientists have successfully demonstrated that laser-induced filaments in the sky can guide lightning discharges over long distances, potentially leading to progress in lightning protection and physics. The research, conducted on a mountain in Switzerland using a high-repetition-rate terawatt laser, recorded the guidance of an upward negative lightning leader over a distance of 50m and was corroborated by other measurements. This is the first field-result to experimentally demonstrate lightning guided by lasers, opening the possibility for new atmospheric applications of ultrasho… Read More
Light contains both energy and momentum that can be used for various types of optical manipulation such as levitation and rotation. Optical tweezers, for example, are commonly used scientific instruments that use laser light to hold and manipulate tiny objects such as atoms or cells. For the last ten years, scientists have been working on a new type of optical manipulation: using laser light to create an optical tractor beam that could pul… Read More
NASA is using tabletop exercises to test how electric air taxis will fit safely into the national airspace, allowing passengers to one day hop across town or to a neighboring city. The agency partnered with industry, academia, and other government agencies in a series of 10 expert-led tabletop exercises to examine technical, operational, and regulatory gaps and define the best use of combined resources to add… Read More
The breakthrough came in an impossibly small slice of time, less than it takes a beam of light to move an inch. In that tiny moment, nuclear fusion as an energy source went from far-away dream to reality. The world is now grappling with the implications of the historic milestone. For Arthur Pak and the countless other scientists who’ve spent decades getting to this point, the work is just beginning…
We found that a typical commercial toilet generates a strong upward jet of air with velocities exceeding 6.6 feet per second (2 meters per second), rapidly carrying these particles up to 5 feet (1.5 meters) above the bowl within eight seconds of the start of th… Read More
Toilets are designed to efficiently empty the contents inside the bowl through a downward motion into the drain pipe. In the flush cycle, water comes into forceful contact with the contents inside the bowl and creates a fine spray of particles suspended in air.

The AC-130 is one of the US military’s most capable aircraft. Ground troops love the gunship and the capabilities it brings to the fight, but it can be effective even without deploying its large arsenal. During the chaotic evacuation of Kabul, Afghanistan, in August 2021, two AC-130J Ghostrider crews used a little-known laser sensor on their planes to help control the situation around the airport and keep enemy forces at bay as friendly troops carried out the e… Read More
At a range in southern England, researchers tested a new laser, making it one step closer to military use.
