Terahertz (THz) radiation is used today most prominently for security screening at the airport. It’s the machine you stand in with your hands up as it swings its scanning arms in front and behind you. In medicine, terahertz imaging has the potential to help diagnoze certain types of cancer and to monitor a variety of health parameters to aid in assessment of overall health. Because of the extremely short length of terahertz waves, this imaging modality has a lot of limitations, including shallow penetration into tissues, and that prevents it from being used more widely. Yet, since it’s non-ionising, it’s probably safe and may even replace dangerous X-rays for some applications.

Currently, terahertz imaging is very poor at scanning curved surfaces even though it can peer a few millimeters deep into some tissues. To overcome this, researchers at Tokyo Institute of Technology have developed a flexible and even wearable terahertz scanner that can image curved 3D surfaces such as our skin.

Made of 23 carbon nanotube detectors that work as a unified imaging array, their device can be wrapped around a finger, for example. Because carbon nanotubes are able to absorb a wide range of terahertz radiation, there’s no need for planar antennas.

No autonomous cars, planes, ships, weapons (not sure I would even still want these), and other robots for me until we have our Net and other infrastructure replaced with QC.


It seems that all of Silicon Valley is designing artificial intelligence for driverless cars. But before we hand over our driving to computers, Charlie Miller, a well-known computer security researcher, would like car companies to pay attention to security.

Miller, who is a security engineer at Uber’s advanced technology center, spent a few years looking into the security of automobiles. And what he found didn’t impress him. He and his friend Chris Valasek hacked a Jeep remotely in 2014, and, after a series of denials from the car company, Chrysler had to announce a recall of 1.4 million vehicles. Miller gave a scary and hilarious talk at the recent ARM TechCon event in Santa Clara, Calif.

“Hopefully, things are going to get better, but we are not in such great shape now,” said Miller. “I want [car makers] to be working on security, and I would love greater transparency. I would love to see white papers written by car makers on exactly how their systems are designed for security. Then I could spend a weekend reading their white paper rather than two years tearing apart their cars.”

Telegram has announced the first winners of its bot competition. The BotPrize was announced in April and will see $1 million awarded to developers of the best Telegram bots submitted. The first winners come from the worlds of photo-editing, productivity, games, dating and finance.

Telegram is a messaging service with a focus on speed and security. Launched in 2013, it is cloud-based, meaning that user content syncs instantly across the platforms on which the service can be used, including PC, Mac, Linux, Android, iOS and Windows Phone.

The firm’s BotPrize will help to increase the number of bots available on the service and accelerate the speed with which the number is increased. For the uninitiated, bots are effectively apps in themselves with which users can interact via messaging. They typically run inside messaging apps such as Facebook Messenger or, in this instance, Telegram.

Tune in tomorrow (Thursday, Nov 10, 2016) at 4:30PM Eastern. Find out what Edward Snowden has to say on the future of the US. [Source: StartPage via Engadget]

American technology policies could change significantly under Donald Trump, and that includes its stance on privacy. How will the new leader alter government surveillance, for example? Edward Snowden might have an answer. The whistleblower and Dutch search engine StartPage are hosting a live event on November 10th at 4:30PM Eastern to address what happens to privacy in the Trump era, among other questions. Snowden speaking engagements are nothing new, but this is special — he’s more than a little familiar with government spying activities, and this is his first chance to opine on how things might be different under a new administration.

Snowden hasn’t said much of anything about the subject as of this writing. However, Trump doesn’t exactly have a stellar record on internet privacy so far. He has proposed reauthorizing the Patriot Act and the previous, less restrained NSA mass surveillance that took place while the Act was in force. He tends to “err on the side of security” over privacy, even if he’s not especially fond of it. As such, Snowden probably won’t have many kind things to say. He’s in favor of more privacy wherever possible, and that could easily put him at greater odds with the US government than he is now.

We have already seen the HoloLens mixed reality headset put to military use by the Israeli Defense Force for advanced battlefield planning.

Now Ukrainian company LimpidArmor has shown off a new application for the augmented reality device on the actual battlefield to improve the field of view of tank commanders without exposing them to additional risk. The technology was shown off at the Arms and Security show, held in Kiev from 11 to 14 October.

LimpidArmor’s hardware and software system uses a HoloLens integrated with a helmet and cameras mounted around the tank to give commanders a 360 degree view of their environment in both optical and thermal and makes this available in real-time.

What does the future hold for computing? Experts at the Networked Quantum Information Technologies Hub (NQIT), based at Oxford University, believe our next great technological leap lies in the development of quantum computing.

Quantum computers could solve problems it takes a conventional computer longer than the lifetime of the universe to solve. This could bring new possibilities, such as advanced drug development, superior military intelligence, greater opportunities for and enhanced encryption security.

Quantum computers also present real risks, but scientists are already working on new forms of encryption that even a quantum computer couldn’t crack. Experience tells us that we should think about the applications and implications of quantum computing long before they become reality as we strive to ensure a safe future in the exciting new age of .

Microcomputers are great for learning about code and hardware. The VoCore2 Mini is the smallest ever, packing full Linux functionality and wireless connectivity into a coin-sized device. New Atlas Deals has it for just $42.99.

This impressive little computer is capable of running programs in C, Java, Ruby, JavaScript, and many other languages. This means you can code the VoCore2 to expand its functionality, turning it into a VPN gateway, airplay music station, and much more.

You can also augment the VoCore2 with hardware components for further tinkering fun. Add a USB webcam to turn it into a home security camera, attach a microphone to issue voice commands to Siri or Echo, and so on. Your projects are limited only by your imagination.

Could technology build friendships for Israel across the Middle East?


Israel and Saudi Arabia should form a “collaborative alliance” to become the “twin pillars of regional stability” in the Middle East, a top Saudi lobbyist wrote in The Hill on Tuesday, in what is the latest sign of warming and increasingly-public ties between Arab countries and the Jewish state.

Salman al-Ansari, the founder and president of the Saudi American Public Relations Affairs Committee, asserted that Israel can assist Saudi Arabia in implementing its Vision 2030, the Kingdom’s blueprint to diversify its economy. Al-Ansari specifically mentioned Israel’s expertise in mining and water technology, which makes Israel “extraordinarily qualified to help Saudi Arabia with its ambitious desalination plans.”

Deputy Crown Prince Mohammed bin Salman, the man in charge of implementing Vision 2030, “is prepared and willing to develop real, enduring ties with Israel,” al-Ansari wrote, adding, “Any form of normalization between the two countries is also an Arabic and Muslim normalization towards Israel, which will undoubtedly promote security and weaken extremism in the region.”
