New way for IoT and data centers in general to improve energy use, costs, etc.
Arrays based on vertical-cavity surface-emitting lasers offer a high-bandwidth, low-power, and low-cost solution for intra-data centers.
China is going to try to own tech and be the SV for the world within the next 7 years. This is definitely in process and many companies in China have been rejecting US tech products for the past several months due to US pressures about the S. China Sea and ramp up efforts to build their own tech companies to take down Apple, Google, Microsoft, etc. They do have the IP to possibly do it.
So, move over FB, Youtube, and Amazon, there is a new streaming media competitor on the horizon coming to online users near you. Lookout the remaining parts of Alphabet (namely Google), Amazon, and Microsoft.
China’s LeEco doesn’t come up much when China’s top tech firms are mentioned. Maybe it should.
The main goal of a tumour cell is, above all, to survive, even at the cost of damaging the health of the organism to which it belongs.
To do this, it is equipped with skills that healthy cells do not have, including the ability to continue surviving when glucose levels are very low.
This could be one of the reasons why widely-used anti-angiogenic agents often fail to eliminate cancer, no matter how much they starve it by hindering the development of the blood vessels that provide nutrients in general and glucose in particular.

Smart homes that repairs themselves. Why not since 4D-Printing enables self-assembly.
DARPA has unveiled the Engineered Living Materials program that combines living systems with traditional building materials for on-demand and self-repairing material that cuts cost and energy.

I already voiced my concerns of this technology in the hands of criminals and terrorists. If we can have it so can others. Only when QC and a Quantum net is in place will we be truly protected with bots.
Cybersecurity could soon be another place where bots become invaluable for experts. DARPA recently organized The Cyber Grand Challenge, where computer algorithms showed how easy it is to clean up vulnerabilities in code written by humans. ( DARPA )
The Cyber Grand Challenge took place under DARPA patronage, and it is good to see how preoccupied the U.S. Department of Defense is with cybersecurity.
Well, we can easily figure out who this and how this will be used on.
Wireless transmitters that operate at very or ultra low frequencies (0.3‐30 kHz) typically require some big antenna complexes to handle their communications.
Scientists at the Defense Advanced Research Projects Agency (DARPA) said they are interested looking to eliminate that issue and develop smaller physical structures that could handle new long-distance communication applications.

I will like to see how this stacks against China’s Quantum net, QC platform, AI, and hackers in the future. Not sold at this point until we truly have a QC infrastructure in place.
At DARPA’s Cyber Grand Challenge, bots showed off their ability to help a world wallowing in vulnerable code.
LAS VEGAS, Nev. — Mayhem ruled the day when seven AIs clashed here last week — a bot named Mayhem that, along with its competitors, proved that machines can now quickly find many types of security vulnerabilities hiding in vast amounts of code.
Dmitry Fedyanin from the Moscow Institute of Physics and Technology and Mario Agio from the University of Siegen and LENS have predicted that artificial defects in the crystal lattice of diamond can be turned into ultrabright and extremely efficient electrically driven quantum emitters. Their work, published in New Journal of Physics, demonstrates the potential for a number of technological breakthroughs, including the development of quantum computers and secure communication lines that operate at room temperature.
The research conducted by Dmitry Fedyanin and Mario Agio is focused on the development of electrically driven single-photon sources—devices that emit single photons when an electrical current is applied. In other words, using such devices, one can generate a photon “on demand” by simply applying a small voltage across the devices. The probability of an output of zero photons is vanishingly low and generation of two or more photons simultaneously is fundamentally impossible.
Until recently, it was thought that quantum dots (nanoscale semiconductor particles) are the most promising candidates for true single-photon sources. However, they operate only at very low temperatures, which is their main drawback – mass application would not be possible if a device has to be cooled with liquid nitrogen or even colder liquid helium, or using refrigeration units, which are even more expensive and power-hungry. At the same time, certain point defects in the crystal lattice of diamond, which occur when foreign atoms (such as silicon or nitrogen) enter the diamond accidentally or through targeted implantation, can efficiently emit single photons at room temperature. However, this has only been achieved by optical excitation of these defects using external high-power lasers. This method is ideal for research in scientific laboratories, but it is very inefficient in practical devices.
Quantum computers are largely hypothetical devices that could perform some calculations much more rapidly than conventional computers can. Instead of the bits of classical computation, which can represent 0 or 1, quantum computers consist of quantum bits, or qubits, which can, in some sense, represent 0 and 1 simultaneously.
Although quantum systems with as many as 12 qubits have been demonstrated in the lab, building quantum computers complex enough to perform useful computations will require miniaturizing qubit technology, much the way the miniaturization of transistors enabled modern computers.
Trapped ions are probably the most widely studied qubit technology, but they’ve historically required a large and complex hardware apparatus. In today’s Nature Nanotechnology, researchers from MIT and MIT Lincoln Laboratory report an important step toward practical quantum computers, with a paper describing a prototype chip that can trap ions in an electric field and, with built-in optics, direct laser light toward each of them.
