At my first reading of your headline, I wondered where in the world Jahania was. Time for more coffee, I guess.
Carnegie Mellon University has named computer science professor and Arbor Networks founder Farnam Jahanian as its new president. The researcher-turned-entrepreneur-turned-administrator takes over the permanent position after an eight-month temporary turn as president. Previously, he had led the university's academic department …
Nothing in the quantum hardware world is fully cooked yet, but quantum computing is quite a bit further along than quantum networking – an esoteric but potentially significant technology area, particularly for ultra-secure transactions. Amazon Web Services is among those working to bring quantum connectivity from the lab to the real world.
Short of developing its own quantum processors, AWS has created an ecosystem around existing quantum devices and tools via its Braket (no, that's not a typo) service. While these bits and pieces focus on compute, the tech giant has turned its gaze to quantum networking.
Alongside its Center for Quantum Computing, which it launched in late 2021, AWS has announced the launch of its Center for Quantum Networking. The latter is grandly working to solve "fundamental scientific and engineering challenges and to develop new hardware, software, and applications for quantum networks," the internet souk declared.
Mega, the New Zealand-based file-sharing biz co-founded a decade ago by Kim Dotcom, promotes its "privacy by design" and user-controlled encryption keys to claim that data stored on Mega's servers can only be accessed by customers, even if its main system is taken over by law enforcement or others.
The design of the service, however, falls short of that promise thanks to poorly implemented encryption. Cryptography experts at ETH Zurich in Switzerland on Tuesday published a paper describing five possible attacks that can compromise the confidentiality of users' files.
The paper [PDF], titled "Mega: Malleable Encryption Goes Awry," by ETH cryptography researchers Matilda Backendal and Miro Haller, and computer science professor Kenneth Paterson, identifies "significant shortcomings in Mega’s cryptographic architecture" that allow Mega, or those able to mount a TLS MITM attack on Mega's client software, to access user files.
Sometimes it takes research to prove what was already suspected, like how utterly uncomfortable it would be to work in the metaverse.
An international team of researchers conducted a study [PDF] to just such an end, putting participants in VR headsets and taking an inventory of their self-reported physical and mental states throughout a five day, eight-hour-a-day period spent in headsets and a virtual "office".
Unlike a real job, participants were allowed to set their own work agendas and didn't perform standardized tasks yet even still had trouble undertaking these.
Chinese academics have christened an ocean research vessel that has a twist: it will sail the seas with a complement of aerial and ocean-going drones and no human crew.
The Zhu Hai Yun, or Zhuhai Cloud, launched in Guangzhou after a year of construction. The 290-foot-long mothership can hit a top speed of 18 knots (about 20 miles per hour) and will carry 50 flying, surface, and submersible drones that launch and self-recover autonomously.
According to this blurb from the shipbuilder behind its construction, the Cloud will also be equipped with a variety of additional observational instruments "which can be deployed in batches in the target sea area, and carry out task-oriented adaptive networking to achieve three-dimensional view of specific targets." Most of the ship is an open deck where flying drones can land and be stored. The ship is also equipped with launch and recovery equipment for its aquatic craft.
Video Robot boffins have revealed they've created a half-millimeter wide remote-controlled walking robot that resembles a crab, and hope it will one day perform tasks in tiny crevices.
In a paper published in the journal Science Robotics , the boffins said they had in mind applications like minimally invasive surgery or manipulation of cells or tissue in biological research.
With a round tick-like body and 10 protruding legs, the smaller-than-a-flea robot crab can bend, twist, crawl, walk, turn and even jump. The machines can move at an average speed of half their body length per second - a huge challenge at such a small scale, said the boffins.
The US Justice Department has directed prosecutors not to charge "good-faith security researchers" with violating the Computer Fraud and Abuse Act (CFAA) if their reasons for hacking are ethical — things like bug hunting, responsible vulnerability disclosure, or above-board penetration testing.
Good-faith, according to the policy [PDF], means using a computer "solely for purposes of good-faith testing, investigation, and/or correction of a security flaw or vulnerability."
Additionally, this activity must be "carried out in a manner designed to avoid any harm to individuals or the public, and where the information derived from the activity is used primarily to promote the security or safety of the class of devices, machines, or online services to which the accessed computer belongs, or those who use such devices, machines, or online services."
Video Engineers at MIT have created paper-thin speakers using a plastic film and a piezoelectric layer embossed with tiny domes.
These sheet speakers could potentially be applied to any surface for sound output or input: think surround sound or noise cancellation in aircraft. The technology also has potential for ultrasound imaging and echolocation, among other possibilities.
The work is described in a paper published recently in the journal IEEE Transactions on Industrial Electronics, "An Ultra-Thin Flexible Loudspeaker Based on a Piezoelectric Micro-Dome Array."
Researchers in the US have received a $15 million National Science Foundation (NSF) award to develop superconductor chips that ought to be much faster and use significantly less energy than the hardware the world today relies on for computing.
A team at the University of Southern California's Viterbi School of Engineering is leading the effort, and it goes by the name DISCoVER, a rather fun acronym that stands for Design and Integration of Superconductive Computation for Ventures beyond Exascale Realization.
As the name suggests, the scientists are looking to use superconducting materials as an alternative to today's semiconductors to develop new kinds of superfast and highly energy efficient integrated circuits that can enable sustainable and large-scale exascale computing.
You may have heard before about Intel's Loihi neuromorphic chips that mimic the way brains work, but what hasn't been clear yet is how the chipmaker will make money from the experimental silicon.
In a recent roundtable with journalists, Intel Labs lead Rich Uhlig offered two possibilities: integrating Loihi in a CPU for PCs to perform energy-efficient AI tasks and potentially offering the its neuromorphic chips as a cloud service, although Uhlig was clear he wasn't firming actual product plans, just projecting what could theoretically happen in the future.
"Right now with Loihi, we're at that point where we think we're onto something, but we don't actually have product plans yet. We're sort of earlier on in that work stream," he said last month.
Analysis Intel is cranking up its research spending to fix past mistakes, catch up with and overtake the competition, and build a foundation to grow in future.
The US giant spent $15.19bn on research and development in fiscal 2021, more than 20 per cent of the company's $74.7bn revenue. That was about a 12 per cent increase from research and investments in 2020, and it was largest year-over-year increase since 2012, when R&D spending went up by 20 per cent.
Compare that to recent years, when research and development spending was stagnant or barely increased and Chipzilla spent billions on stock price support instead. Enter CEO Pat Gelsinger, who took the reins last year and hit the reset button on Intel's priorities to focus on engineering.
