O.o!
The epic collision between two neutron stars in 2017 really is the science gift that keeps on giving. As they merged, gravitational waves rippled out across the Universe; now reverberations from that event could confirm a decades-old hypothesis about black holes.
Astronomers poring over the gravitational wave data believe they have found evidence of echoes — something that would only occur in the presence of the ‘quantum fuzz’ produced by Hawking radiation.
O.o circa 2015.
Researchers from the Australian National University (ANU) and the University of Otago in New Zealand have created a prototype quantum hard drive that may fundamentally alter the realm of secure, long-distance data encryption. Using atoms of the rare-earth element europium embedded in yttrium orthosilicate (YSO) crystals, the scientists have shattered previous records for quantum information retention by creating a storage device capable of holding quantum state information for up to six hours at a time.
Quantum data encryption already offers the promise of intrinsically secure electronic data interchange over relatively short distances (up to around 100 km (62 mi) or so). However, this latest research may help enable a worldwide quantum-encrypted communications network by providing unprecedented storage capabilities and effectively negating the instability problems inherent in currently available technology.
“We believe it will soon be possible to distribute quantum information between any two points on the globe,” said Manjin Zhong, a researcher on the project from the ANU’s Research School of Physics and Engineering (RSPE). “Quantum states are very fragile and normally collapse in milliseconds. Our long storage times have the potential to revolutionize the transmission of quantum information.”
Traditionally, India’s best and brightest tech talent has emigrated to the United States for lucrative job opportunities. But now they’re putting their entrepreneurial spirit and engineering skills to use at home.

Bernardeta Gómez has been blind for 16 years. But using a bionic eye developed by Spanish neuroengineer Eduardo Fernandez, she was able to see again — without using her biological eyes at all.
The system, which Fernandez is honing at his University of Miguel Hernandez lab, comprises a few different parts, as detailed in a newly-published story in MIT Technology Review.
First, there’s a pair of glasses fitted with a camera that connects to a computer. The computer translates the camera’s live video feed into electronic signals. Those signals are then sent via a cable to a port that Fernandez surgically embedded in the back of Gómez’s skull. That port connects to an implant in the visual cortex of Gómez’s brain.

There are many satellites in space and we know which launch put most of them up there. But there are a number of them that are not associated with a specific launch, though it would be desirable to identify which put them into orbit. This article is about a technique which could help associate objects in space with particular launches, one that I am currently developing. But let’s start with some background information: what do we know about most satellites?
First, there are several catalogs of satellites. These are lists of satellites and information about them, and are maintained by different organizations. What are these catalogs? I have written a couple of articles that have appeared here that give some background, such as one about overlooked satellites (see “Acknowledging some overlooked satellites”, The Space Review, June 12, 2017), while another discusses why some satellites are in some catalogs and not others (see “Time for common sense with the satellite catalog”, The Space Review, April 10, 2017).
The US Air Force maintains the default world official satellite catalog and assigns official satellite numbers and “international designators,” which state what launch each object is associated with. The Air Force gets observations from many sites, radar and optical, around the world and uses them to generate and maintain orbital parameters for satellites. That is how they know which object is from which launch. That international designator is very important when a satellite reenters: the country that owns a satellite that reenters is responsible for any damage caused when it impacts the ground. Also, for satellite collisions, the country that owns a satellite that “causes” a collision is responsible for damage.
