Polarization: From better sunglasses to a better way of looking at asteroid surfaces
Using the same principles that make polarized sunglasses possible, a team of researchers at the Arecibo Observatory in Puerto Rico have developed a technique that will help better defend against asteroids on a collision course with Earth......»»
Alert fatigue puts pressure on security and development teams
Security practitioners are under a tremendous amount of pressure to secure today’s applications, according to Cycode. The research found that AppSec chaos reigns, with 78% of CISOs responding that today’s AppSec attack surfaces are unmanageable a.....»»
Earth may have had all the elements needed for life—contrary to theories that they came from meteorites
For many years, scientists have predicted that many of the elements that are crucial ingredients for life, like sulfur and nitrogen, first came to Earth when asteroid-type objects carrying them crashed into our planet's surface......»»
Engineers develop a way to determine how the surfaces of materials behave
Designing new compounds or alloys whose surfaces can be used as catalysts in chemical reactions can be a complex process relying heavily on the intuition of experienced chemists. A team of researchers at MIT has devised a new approach using machine l.....»»

NASA finds likely cause of OSIRIS-REx parachute deployment sequence
NASA's OSIRIS-REx sample return capsule landed under parachute in the Utah desert on Sept. 24, 2023, and safely delivered a cannister of rocks and dust collected from near-Earth asteroid Bennu. Although the delivery was successful, the landing sequen.....»»
Living Security Unify Go improves human risk management
Living Security announced Unify Go, a free tool for Living Security training customers that surfaces security vulnerabilities across the workforce by aggregating and correlating employee behavior across security training, phishing, and email security.....»»
Exploring acoustic design for better, quieter prisons
Prisons are typically noisy environments, filled with clanking metal bars and echoing concrete surfaces. This level of constant noise is harmful to both prisoners and staff, but there are few guidelines for designing better, quieter facilities......»»
Exploring the limitations of asteroid crater lakes as climate archives
In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this spot. Today, the impact crater is one of the most useful a.....»»
NASA’s skywatching tips for December include a meteor shower
NASA's skywatching tips for December include a meteor shower and the chance to spot a passing asteroid with your own eyes......»»
Zoom app for Apple TV surfaces in the App Store
The video conferencing app Zoom has quietly arrived on Apple TV 4K, allowing users to conduct meetings via their television and an iPhone or iPad.When Apple introduced tvOS 17 in June, it said that FaceTime calls were arriving on Apple TV 4K, with Zo.....»»
What’s new on Amazon Prime Video in December 2023
Asteroid City, Sound of Freedom, and Reacher season 2 are landing on Amazon Prime Video in December 2023, and then it's bombs away on Christmas with The Flash......»»
Control over friction, from small to large scales
Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, even at large scales, is determined by the formin.....»»
Researchers develop a new approach to polarization-independent LC phase modulation
Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements. However, most LC phase modulators are polarization.....»»
Contact binary asteroids are common, but we"ve never seen one form. Now, researchers want to make one
Ever want to play a game of cosmic billiards? That's commonly how the DART mission was described when it successfully changed the orbit of a near-Earth asteroid last year. If you want an idea of how it works, just Google it and an Easter egg from the.....»»
Bidding adieu to sticky ice, but with a grain of salt
As Americans gear up for winter, many will face one of their toughest foes: ice. From delaying flights to making roads slippery, ice accumulation on surfaces wreaks havoc in many ways......»»
Researchers develop coating process for fabrics that kills or inhibits growth of pathogens
Countless times a day, patients, visitors and medical staff in hospitals touch surfaces of all kinds. Door handles, railings or elevator buttons can serve as transport vehicles for pathogens such as hospital germs or viruses. Smooth surfaces are comp.....»»
Dynamic z-scanning for ultrafast auto-focusing in laser processing
In laser-based manufacturing, accommodating non-flat, or changing surfaces has traditionally been labor-intensive, involving complex focus mapping procedures and or ex-situ characterization. This often results in repositioning errors and extended pro.....»»
If you"re trying to prevent an asteroid impact, the technical and political challenges are staggering
While preparing for the threat of an asteroid strike might seem like a hypothetical exercise, it's really not. The solar system has calmed down a lot from earlier times when impacts were more frequent. But it is only a matter of time before an astero.....»»
Chlorine disinfectant is no more effective than water at killing off hospital superbug, new study shows
One of the primary chlorine disinfectants currently being used to clean hospital scrubs and surfaces does not kill off the most common cause of antibiotic-associated sickness in health care settings globally, according to a new study......»»
