Tethers Unlimited, Inc. (TUI) announced that it has signed a Public-Private Partnership with NASA to deliver a HYDROS™ propulsion system for a CubeSat mission. Concurrently, TUI has signed an associated contract to provide three HYDROS thrusters sized for Millennium Space Systems’ (MSS) ALTAIR™ class microsatellites to support three different flight missions. Total contract value for the two efforts is $2.2M.

The HYDROS propulsion system uses in-space electrolysis of water to generate hydrogen and oxygen gas, which it then burns in a bipropellant thruster. This water-electrolysis method allows small satellites to carry a propellant that is non-explosive, non-toxic, and unpressurized. The hydrogen and oxygen generated on-orbit will enable high-thrust and high-fuel-efficiency propulsion so these small satellites can perform missions requiring orbital agility and long-duration station-keeping.

The partnership with NASA is a cost-sharing program funded under NASA’s Space Technology Mission Directorate’s “Utilizing Public-Private Partnerships to Advance Tipping Point Technologies” Program. In this effort, TUI will conduct lifetime and environmental testing of prototypes of HYDROS systems sized for CubeSats and microsatellites and then deliver a flight unit HYDROS thruster intended for testing on a CubeSat mission as part of NASA’s Pathfinder Technology Demonstration Program, at Ames Research Center, Moffett Field, California.

Philadelphia, PA, USA / Mexico City, Mexico — Bioquark, Inc., (www.bioquark.com) a life sciences company focused on the development of novel bioproducts for complex regeneration, disease reversion, and aging, and RegenerAge SAPI de CV, (www.regenerage.clinic/en/) a clinical company focused on translational therapeutic applications of a range of regenerative and rejuvenation healthcare interventions, have announced a collaboration to focus on novel combinatorial approaches in human disease and wellness. SGR-Especializada (http://www.sgr-especializada.com/), regulatory experts in the Latin American healthcare market, assisted in the relationship.

“We are very excited about this collaboration with RegenerAge SAPI de CV,” said Ira S. Pastor, CEO, Bioquark Inc. “The natural synergy of our cellular and biologic to applications of regenerative and rejuvenative medicine will make for novel and transformational opportunities in a range of degenerative disorders.”

As we close in on $7 trillion in total annual health care expenditures around the globe ($1 trillion spent on pharmaceutical products; $200 billion on new R&D), we are simultaneously witnessing a paradoxical rise in the prevalence of all chronic degenerative diseases responsible for human suffering and death.

China and the US; tensions are mounting and China’s new Quantum Satellite is aiding more fuel to the flames.

By: James Holbrooks (UndergroundReporter) Beijing — Only days after completing production of the largest amphibious aircraft ever built, China has just revealed plans to launch the world’s first satellite designed to conduct quantum experiments in space — a move that could one day lead to a highly secure “orbital internet.”

Assuming the initial satellite performs well, as many as 20 additional craft would follow in the effort to create a new category of communications network. Chinese researchers believe their work could ignite a space race as other nations move to refine the technology.

An elliptical light beam in a nonlinear optical medium pumped by “twisted light” can rotate like an electron around a magnetic field.

Magnetism and rotation have a lot in common. The effect of a magnetic field on a moving charge, the Lorentz force, is formally equivalent to the fictitious force felt by a moving mass in a rotating reference frame, the Coriolis force. For this reason, atomic quantum gases under rotation can be used as quantum simulators of exotic magnetic phenomena for electrons, such as the fractional quantum Hall effect. But there is no direct equivalent of magnetism for photons, which are massless and chargeless. Now, Niclas Westerberg and co-workers at Heriot-Watt University, UK, have shown how to make synthetic magnetic fields for light [1]. They developed a theory that predicts how a light beam in a nonlinear optical medium pumped by “twisted light” will rotate as it propagates, just as an electron will whirl around in a magnetic field. More than that, the light will expand as it goes, demonstrating fluid-like behavior.

Lateral photonic integration of oxide-confined leaky vertical-cavity surface-emitting lasers enables their application in data communications and sensing.

Vertical-cavity surface-emitting lasers (VCSELs) that operate at 850nm and are based on oxide-confined apertures are widely used in optical interconnects in data centers, supercomputers, wireless backbone networks, and consumer applications.¹ As the processor productivity in these applications increases, it is necessary to continuously improve performance and scale transmission speeds accordingly. In recent years, developers have produced a generation of devices capable of transmitting 40Gb/s at moderate current densities,^{2, 3} and they have recently demonstrated 54Gb/s non-return-to-zero transmission through 2.2km of multimode fiber.⁴ Now, 108Gb/s per wavelength transmission can be realized over 100–300m of multimode fiber through the use of advanced modulation formats: discrete multi-tone,⁵ multiCAP,⁶ and PAM4.

Nice!

IBM scientists have developed a new lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could help enable physicians to detect diseases such as cancer before symptoms appear.

As reported today in the journal Nature Nanotechnology (“Nanoscale Lateral Displacement Arrays for Separation of Exosomes and Colloids Down to 20nm”), the IBM team’s results show size-based separation of bioparticles down to 20 nanometers (nm) in diameter, a scale that gives access to important particles such as DNA, viruses and exosomes. Once separated, these particles can be analyzed by physicians to potentially reveal signs of disease even before patients experience any physical symptoms and when the outcome from treatment is most positive. Until now, the smallest bioparticle that could be separated by size with on-chip technologies was about 50 times or larger, for example, separation of circulating tumor cells from other biological components.

Researchers find that nanoparticles show promise for fighting tooth plaque — in rats, at least.

Could we see a day when 3D Printers replace convection ovens and microwaves in the kitchen?

Over the last few decades, a new wave of science has been infused into the world of food in the form of molecular gastronomy. By definition, food preparation and cooking involve physical and chemical changes, and molecular gastronomy simply uses scientific principles to take food in new technical and even artistic directions.
