Scientists Create Functional Model of a Living and Breathing Supercomputer

Posted by in categories: bioengineering, energy, supercomputing

In what appears at first to be a storyline ripped from a sci-fi thriller, a multi-national research team spread across two continents, four countries, and ten years in the making have created a model of a supercomputer that runs on the same substance that living things use as an energy source.

Humans and virtually all living things rely on Adenosine triphosphate ( ATP ) to provide the energy our cells need to perform daily functions. The biological computer created by the team led by Professor Dan Nicolau, Chair of the Department of Bioengineering at McGill, also relies on ATP for power.

The biological computer is able to process information very quickly and operates accurately using parallel networks like contemporary massive electronic super computers. In addition, the model is lot smaller in size, uses relatively less energy, and functions using proteins that are present in all living cells.

Mysterious Cosmic Radio Bursts Just Got Even More Interesting

Posted by in categories: energy, space

Fast radio bursts, or FRBs, are a source of endless fascination. But despite a decade of observations, not all astronomers are sure that they’re real. A study out in Nature today, which reports the very first recurring FRB, is now causing lingering skepticism to evaporate.

“I think this is pretty huge,” Peter Williams, an astronomer at Harvard’s Center for Astrophysics who was not involved with the study, told Gizmodo. “For awhile, I wasn’t sure these things were genuinely astrophysical. This paper settles the question.”

And Williams is not one to take splashy new claims about FRBs—high energy radio pulses of unknown origin, which flit across the sky for a fraction of a second—lightly. In fact, he’s spent the last week raising major doubts about another recent study, which, as Gizmodo and other outlets reported, claimed to have pinpointed the location of an FRB in space for the first time.

‘Very Close’: Pentagon’s Death Laser Right Around the Corner

Posted by in categories: energy, military

A new laser tag coming our way; however, this time when you’re tagged, you really are dead.


US officials tout the ‘unprecedented power’ of killing lasers to be released by 2023.

The US Army will deploy its first laser weapons by 2023, according to a recently released report.

Utilities Cautioned About Potential for a Cyberattack After Ukraine’s

Posted by in categories: cybercrime/malcode, energy

Working remotely, attackers conducted “extensive reconnaissance” of the Ukraine power system’s networks, stole the credentials of operators and learned how to switch off the breakers, plunging more than 225,000 Ukrainians into darkness.

Australia’s coast, being both great surf territory as well as a primo shark habitat, is getting a technological upgrade to keep the swimmer-fish twain from meeting: A shark-spotting drone nicknamed the “Little Ripper.”

A joint venture between Aussie philanthropist Ken Weldon and Aussie bank Westpac, the $250,000 battery-powered unmanned helicopter will be deployed in the skies above New South Wales. On Sunday, New South Wales Premier Mike Baird heralded the drone as the future of oceanic search and rescue.

Quantum dot solids: a new era in electronics?

Just as the single-crystal silicon wafer forever changed the nature of communication 60 years ago, Cornell researchers hope their work with quantum dot solids — crystals made out of crystals — can help usher in a new era in electronics.

Researchers upgraded their smart glasses with a low-power multicore processor to employ stereo vision and deep-learning algorithms, making the user interface and experience more intuitive and convenient

Posted by in categories: augmented reality, energy, engineering, information science, internet, mobile phones, wearables

K-Glass, smart glasses reinforced with augmented reality (AR) that were first developed by the Korea Advanced Institute of Science and Technology (KAIST) in 2014, with the second version released in 2015, is back with an even stronger model. The latest version, which KAIST researchers are calling K-Glass 3, allows users to text a message or type in key words for Internet surfing by offering a virtual keyboard for text and even one for a piano.

Currently, most wearable head-mounted displays (HMDs) suffer from a lack of rich user interfaces, short battery lives, and heavy weight. Some HMDs, such as Google Glass, use a touch panel and voice commands as an interface, but they are considered merely an extension of smartphones and are not optimized for wearable smart glasses. Recently, gaze recognition was proposed for HMDs including K-Glass 2, but gaze is insufficient to realize a natural user interface (UI) and experience (UX), such as user’s gesture recognition, due to its limited interactivity and lengthy gaze-calibration time, which can be up to several minutes.

As a solution, Professor Hoi-Jun Yoo and his team from the Electrical Engineering Department recently developed K-Glass 3 with a low-power natural UI and UX processor to enable convenient typing and screen pointing on HMDs with just bare hands. This processor is composed of a pre-processing core to implement stereo vision, seven deep-learning cores to accelerate real-time scene recognition within 33 milliseconds, and one rendering engine for the display.

ATR 72 prototype tests all-electrical energy management system

Posted by in categories: electronics, energy, materials, transportation

European turboprop aircraft manufacturer ATR said a prototype ATR 72 conducted a demonstration flight to test an all-electrical energy management system that aims to optimize electrical power distribution.

The flight is the second the ATR 72 demonstration aircraft has flown as part of the European Union’s “Clean Sky Joint Undertaking” program. The first test flight by the ATR 72 prototype, conducted in July 2015, trialed “new and more effective composite insulation materials and new vibro-acoustic sensors integrated into a large panel of the ATR aircraft fuselage,” ATR said in a statement.

The manufacturer said the two demonstration flights “also tested new generation optical fibers for improved identification of micro-cracks and easier maintenance.”

Building Living, Breathing Supercomputers

Posted by in categories: bioengineering, energy, supercomputing

The substance that provides energy to all the cells in our bodies, Adenosine triphosphate (ATP), may also be able to power the next generation of supercomputers. The discovery opens doors to the creation of biological supercomputers that are about the size of a book. That is what an international team of researchers led by Prof. Nicolau, the Chair of the Department of Bioengineering at McGill, believe. They’ve published an article on the subject earlier this week in the Proceedings of the National Academy of Sciences (PNAS), in which they describe a model of a biological computer that they have created that is able to process information very quickly and accurately using parallel networks in the same way that massive electronic super computers do.

Except that the model bio supercomputer they have created is a whole lot smaller than current supercomputers, uses much less energy, and uses proteins present in all living cells to function.

Photonic propulsion cuts Mars travel time

Posted by in categories: astronomy, energy, lifeboat, physics, space travel, transportation

Recent advances in lasers suggest that we may see rockets propelled by light earlier than we had imagined. NASA scientist Philip Lubin and his team are working on a system that would use Earth-based lasers to allow space travel to far-away places in just a fraction of the time needed with current technology.

photonic_propulsion

Using earth based lasers to push along a spacecraft instead of on board hydrocarbon-based fuel could dramatically reduce travel time to Mars, within our lifetime. Currently, it takes five months for a space craft to reach Mars. But, with photonic propulsion, it is likely that small crafts filled with experiments will reach Mars in just 3 days. Large spaceships with astronauts and life support systems will take only one month, which is about 20% of the duration of a current trip.

What’s next? Lubin believes that we may be able to send small crafts with scientific experiments to exoplanets as fast as 5% light speed in, perhaps, 30 years. Eventually, he claims that the technology will carry humans at speeds up to 20% light speed.
