Mass of water vapor that is at least 140 trillion times that of all water in the world’s oceans combined, and 100,000 times more massive than the sun.
A team of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe.
The researchers found a mass of water vapor that is at least 140 trillion times that of all water in the world’s oceans combined, and 100,000 times more massive than the sun.
For a planetarium program intended to show possible future NASA exploration directions, Home Run Pictures was tasked with creating plausible human habitats on the various planets and moons in the Solar System. Engineering concepts required understanding of the environments and the structures or spacecraft necessary for longer term human survival. Avoiding being too science fiction was difficult at times. The surface of Venus is a rough environment with temperatures and pressures at the extreme. But the dense atmosphere seems to allow the possibility of “floating” a space station hanging below some sort of blimp-like structure. An attempt at using what would look like modular structures, similar to what has been used with the International Space Station was implemented. A circular structure was used to keep the station in balance in the turbulent Venusian upper atmosphere with a long strut hanging down from the center to help stabilize the craft and provide mounting points for various experimental packages and docking ports for shuttles or exploratory probes. Small shuttles would drop into the upper atmosphere delivering cargo and personnel. When the station’s scientists desire to dive deeper into the Venus atmosphere for exploration, shuttles that lean more towards the submersibles used for Earth ocean exploration are used. The Venusian atmosphere is very dense and the pressure would crush anything but craft that are constructed like submarines with reinforced portholes instead of windows. Instead of using rocket power for maneuvering, the shuttle/submersible vehicles use large turbo-fan like engines. Everything needs to be constructed of cororsive-resistent materials to survive the acidic Venusian atmosphere. Scientists theorize that massive lighting events would be the norm and electronic and digital hardware would need to be insulated from the extreme electrical environment.
To provide computing power for the U.S. arsenal of advanced weaponry, satellites and information systems, the Pentagon has entered into a seven-year deal with Globalfoundries Inc, an Abu Dhabi-owned microchip manufacturer.
The move serves to diversify the Defense Department’s microchip supply chain — an issue of particular concern for some defense officials — which has been dominated by a short list of sellers led by IBM for over a decade.
A microchip is a small, wafer-thin semiconductor used to relay information through an electrical grid, thereby making an integrated circuit. Almost every modern digital device is chock-full of microchips.

China has been on a shopping tour of Germany, splurging on a string of key industrial companies in the past few weeks as Beijing moves to acquire the country’s fabled technological know-how and turn its own products into global brands.
But resistance to the offensive is growing following a 5 billion euro ($7.7 billion) bid last month by Chinese home appliance group Midea for leading German industrial robot maker Kuka.
The size of the play set alarm bells ringing across the business and political establishment of Europe’s biggest economy.

Medical/ Biocomputing will only continue to grow and advance as a result of the demand for more improved experiences by consumers and business in communications and entertainment, food, home life, travel, business, etc.
Today, we have seen early opportunities and benefits with 3D printing, BMI, early stage Gene/ Cell circuitry and computing. In the future, we will see these technologies more and more replaced by even more advance Biocomputing and gene circuitry technology that will ultimately transform the human experiences and quality of life that many like to call Singularity.
Printing technology has come a long way from screechy dot-matrix printers to 3D printers which can print real life objects from metals, plastics, chemicals and concrete. While, at first, 3D printers were being used to create just basic shapes with different materials, more recently, they have been used to create advanced electronics, bio-medical devices and even houses.
Aircraft manufacturer Airbus recently showcased the world’s first 3D-printed mini aircraft, Thor, at the International Aerospace Exhibition and Air Show in Berlin. Although Airbus and its competitor have been using 3D-printed parts for their bigger assemblies, recent attempt shows that aviation may be ready for a new future with much lighter and cheaper planes given 3D printing not only cuts down the costs with less wastage, it also makes the plane lighter, thereby making them faster and more fuel efficient. But planes and toys is not what 3D printing might be restricted to; though in the elementary stage at the moment, the technology is being used for creating complex electronics like phones and wearables and may be able to reduce costs for manufacturers like Samsung and Apple.

A new twist on AI.
On Tuesday, June 7, the White House Office of Science and Technology Policy’s Lynn Overmann, who also leads the White House Police Data Initiative, stressed the severity of the nation’s incarceration crisis while asking a crowd of data scientists and artificial intelligence specialists for aid.
More news on Google’s AI kill switch — I am glad that it exist.
Developers are pondering on methods to prevent catastrophe in case an Artificial Intelligence, or AI, got ahead of its designated programming.
Theoretical scientist Stephen Hawking, entrepreneur for Tesla Motors Elon Musk, and Microsoft co-founder Bill Gates mentioned that AIs have a high learning curve regarding self-awareness, and anytime soon, AIs might surpass human knowledge and become sentient. In a 2014 interview, theoretical physicist Stephen Hawking stated that the evolution of humans is slower compared to the rapid improvement of robots.

Optica l quantum technologies are based on the interactions of atoms and photons at the single-particle level, and so require sources of single photons that are highly indistinguishable – that is, as identical as possible. Current single-photon sources using semiconductor quantum dots inserted into photonic structures produce photons that are ultrabright but have limited indistinguishability due to charge noise, which results in a fluctuating electric field. Conversely, parametric down conversion sources yield photons that while being highly indistinguishable have very low brightness. Recently, however, scientists at CNRS — Université Paris-Saclay, Marcoussis, France; Université Paris Diderot, Paris, France; University of Queensland, Brisbane, Australia; and Université Grenoble Alpes, CNRS, Institut Néel, Grenoble, France; have developed devices made of quantum dots in electrically-controlled cavities that provide large numbers of highly indistinguishable photons with strongly reduced charge noise that are 20 times brighter than any source of equal quality. The researchers state that by demonstrating efficient generation of a pure single photon with near-unity indistinguishability, their novel approach promises significant advances in optical quantum technology complexity and scalability.
Dr. Pascale Senellart and Phys.org discussed the paper, Near-optimal single-photon sources in the solid state, that she and her colleagues published in Nature Photonics, which reports the design and fabrication of the first optoelectronic devices made of quantum dots in electrically controlled cavities that provide bright source generating near-unity indistinguishability and pure single photons. “The ideal single photon source is a device that produces light pulses, each of them containing exactly one, and no more than one, photon. Moreover, all the photons should be identical in spatial shape, wavelength, polarization, and a spectrum that is the Fourier transform of its temporal profile,” Senellart tells Phys.org. “As a result, to obtain near optimal single photon sources in an optoelectronic device, we had to solve many scientific and technological challenges, leading to an achievement that is the result of more than seven years of research.”
