It’s NICER in Orbit
Given the sheer volume of science going on as the International Space Station circles above our heads every 90 minutes or so, it would be hard for any one experiment to stand out. ISS expeditions conduct experiments on everything from space medicine to astrophysics and beyond, and the instruments needed …read more
Bug in Newly Released iOS 12.0.1 Gives Access To Your Photos
By Waqas
An iOS user Jose Rodriguez, who discovered a passcode bypass related flaw in iOS 12 last month, has now identified another passcode bypass bug in the recently released iOS 12.0.1. According to Rodriguez, a Spanish security researcher, the new … Continue reading Bug in Newly Released iOS 12.0.1 Gives Access To Your Photos

How Lasers Actually Work
Lasers are optical amplifiers, optical oscillators, and in a way, the most sophisticated light source ever invented. Not only are lasers extremely useful, but they are also champions of magnitude: While different laser types cover the electromagnetic spectrum from radiation (<10 nm) over the visible spectrum to far infrared light (699 μm), their individual output band can be as narrow as a few µHz. Their high temporal and spatial coherence lets them cover hundreds of meters in a tight beam of lowest divergence as a perfectly sinusoidal, electromagnetic wave. Some lasers reach peak power outputs of several exawatts, while their …read more
What’s a Piezo Optomechanical Circuit?
Ever hear of a piezo-optomechanical circuit? We hadn’t either. Let’s break it down. Piezo implies some transducer that converts motion to and from energy. Opto implies light. Mechanical implies…well, mechanics. The device, from National Institute of Standards and Technology (NIST), converts signals among optical, acoustic and radio waves. They claim a system based on this design could move and store information in future computers.
At the heart of this circuit is an optomechanical cavity, in the form of a suspended nanoscale beam. Within the beam are a series of holes that act as mirrors for very specific photons. The photons …read more
