Quantum physicists make major nanoscopic advance      (via sciencedaily.com)     Original source 

In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.

Scientists observe 'quasiparticles' in classical systems      (via sciencedaily.com) 

Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs -- a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems.

A butterfly flaps its wings and scientists make jewelry      (via sciencedaily.com) 

In the 'butterfly effect,' an insect can flap its wings and create a microscopic change in initial conditions that leads to a hurricane halfway around the world. This chaos is seen everywhere, from weather to labor markets to brain dynamics. And now researchers explored how to turn the twisting, fractal structures behind the science into jewelry with 3D printing. The jewelry shapes are based on the Chua circuit, a simple electronic system that was the first physical, mathematical, and experimental proof of chaos.

As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving and accurate analytical tools has become increasingly critical -- especially as the hunt for extraterrestrial life and habitable planets or moons continues. A University of Maryland-led team developed a new instrument specifically tailored to the needs of NASA space missions. Their mini laser-sourced analyzer is significantly smaller and more resource efficient than its predecessors--all without compromising the quality of its ability to analyze planetary material samples and potential biological activity onsite.

A soft, stimulating scaffold supports brain cell development ex vivo      (via sciencedaily.com) 

Brain-computer interface companies like Neuralink are in the news a lot these days for their potential to revolutionize how humans interact with machines, but electrodes are not the most brain-friendly materials -- they're hard and stiff, while brains are soft and squishy, which limits their efficacy and increases the risk of damaging brain tissue.  A new hydrogel-based electrode developed at the Wyss Institute solves that problem by providing a tunable, conductive scaffold that human neurons and other cell types feel right at home in. Not only does the scaffold mimic the soft, porous conditions of brain tissue, it supported the growth and differentiation of human neural progenitor cells (NPCs) into multiple different brain cell types for up to 12 weeks. The achievement is reported in Advanced Healthcare Materials. Not only can the new electrode be used to study the formation of human neural networks in vitro, it could enable the creation of implantable devices that more seamlessly integrate with a patient's brain tissue, improving performance and decreasing risk of injury.

While you may be just starting to reap the advantages of 5G wireless technology, researchers throughout the world are already working hard on the future: 6G. One of the most promising breakthroughs in 6G telecommunications is the possibility of Visible Light Communication (VLC), which is like a wireless version of fiberoptics, using flashes of light to transmit information. Now, a team has announced that they have invented a low-cost, innovative way to harvest the waste energy from VLC by using the human body as an antenna. This waste energy can be recycled to power an array of wearable devices, or even, perhaps, larger electronics.
