https://www.3dprintingprogress.com/articles/16697/mobile-bedside-bioprinter-can-heal-wounds Mobile bedside bioprinter can heal wounds Imagine a day when a bioprinter filled with a patient's own cells can be wheeled right to the bedside to treat large wounds or burns by printing skin, layer by layer, to begin the healing process. That day is not far off. For more information see the IDTechEx report on 3D Bioprinting 2018-2028. Wake Forest Institute for Regenerative Medicine (WFIRM) scientists have created such a mobile skin bioprinting system - the first of its kind - that allows bi-layered skin to be printed directly into a wound. "The unique aspect of this technology is the mobility of the system and the ability to provide on-site management of extensive wounds by scanning and measuring them in order to deposit the cells directly where they are needed to create skin," said Sean Murphy, Ph.D., a WFIRM assistant professor who was lead author of the paper published this month in Nature's Scientific Reports journal. Affecting millions of Americans, chronic, large or non-healing wounds such as diabetic pressure ulcers are especially costly because they often require multiple treatments. It is also estimated that burn injuries account for 10-30 percent of combat casualties in conventional warfare for military personnel. The major skin cells - dermal fibroblasts and epidermal keratinocytes - are easily isolated from a small biopsy of uninjured tissue and expanded. Fibroblasts are cells that synthesize the extracellular matrix and collagen that play a critical role in wound healing while keratinocytes are the predominant cells found in the epidermis, the outermost layer of the skin. The cells are mixed into a hydrogel and placed into the bioprinter. Integrated imaging technology involving a device that scans the wound, feeds the data into the software to tell the print heads which cells to deliver exactly where in the wound layer by layer. Doing so replicates and accelerates the formation of normal skin structure and function. The researchers demonstrated proof-of-concept of the system by printing skin directly onto pre-clinical models.
https://www.printedelectronicsworld...could-revolutionize-quantum-dot-manufacturing Nanocrystal 'factory' could revolutionize quantum dot manufacturing North Carolina State University researchers have developed a microfluidic system for synthesizing perovskite quantum dots across the entire spectrum of visible light. The system drastically reduces manufacturing costs, can be tuned on demand to any color and allows for real-time process monitoring to ensure quality control. For more information see the IDTechEx report on Quantum Dot Materials and Technologies 2019-2029. Over the last two decades, colloidal semiconductor nanocrystals, known as quantum dots (QDs), have emerged as novel materials for applications ranging from biological sensing and imaging to LED displays and solar energy harvesting. The new system can be used to continuously manufacture high-quality QDs for use in these applications. "We call this system the Nanocrystal (NC) Factory, and it builds on the NanoRobo microfluidic platform that we unveiled in 2017," says Milad Abolhasani, an assistant professor of chemical and biomolecular engineering at NC State and corresponding author of a paper on the work. "Not only can we create the QDs in any color using a continuous manufacturing approach, but the NC Factory system is highly modular," Abolhasani says. "This means that, coupled with continuous process monitoring, the system allows modifications to be made as needed to eliminate the batch-to-batch variation that can be a significant problem for conventional QD manufacturing techniques. Additionally, the chemistry we have developed in this work allows the perovskite QD processing to take place at room temperature."

With its latest moves, the company is starting to look less like a gear maker selling pricey accessories to fitness buffs and more like a medical-device company, catering to hospitals, patients, and health insurers. The company’s business-to-business arm, called Health Solutions, is now addressing four health conditions—sleep disorders including sleep apnea, diabetes, cardiovascular health and mental health—for employers, health insurers, healthcare providers, and researchers.

If you can’t take a bloody nose, go home and crawl under your bed. It’s not safe out here. It’s wondrous, with treasures to satiate desires both subtle and gross… but it’s not for the timid. -Q Source Nice little piece about magnetars. The book is fantastic!
Quantum physics requires very low temperatures to work, so it would seem to me that the near absolute zero temp of space would be the perfect place to use and test quantum physics. Why are we not hearing anything about this?
Oych... https://www.printedelectronicsworld.com/articles/17508/artificial-muscles-powered-by-glucose "Artificial muscles made from polymers can now be powered by energy from glucose and oxygen, just like biological muscles. This advance may be a step on the way to implantable artificial muscles or autonomous microrobots powered by biomolecules in their surroundings. Researchers at Linköping University, Sweden, have presented their results in the journal Advanced Materials. For more information see the IDTechEx report on New Robotics and Drones 2018-2038. The motion of our muscles is powered by energy that is released when glucose and oxygen take part in biochemical reactions. In a similar way, manufactured actuators can convert energy to motion, but the energy in this case comes from other sources, such as electricity. Scientists at Linköping University, Sweden, wanted to develop artificial muscles that act more like biological muscles. They have now demonstrated the principle using artificial muscles powered by the same glucose and oxygen as our bodies use." Scary!!!
that looks like something in a very far future specially here in the US were medicine is a big time business ...machines that repair the body that dont sound profitable to big pharma and the big hospitals making a killing were the charge 10k a day for a bed.

Actually quantum Physics does not 'work only' at absolutes, the 'issues' Quantum Physics does create there are just more obvious. (Or one can say the absolutes themselves are also 'issues') Low temp is one of the conditions that is easier to create (on earth) to observe quantum fluctuation for instance. At absolute Zero there is actually no thermal energy left for motion. Anyway such Quantum fluctuations have been observed 2011 at Rubidium atoms below minus 273 degrees Celsius. They jumped from one place to another, although there should be no energy therefore left. https://www.mpq.mpg.de/4859180/11_10_14 The common 'issues / attributes' of Quantum Physics: - A particle's location can be at two different places at the same time. - First effect than cause. - The cat is dead and alive at the same time - A close observation turns the things that are observed into their opposite. - Quantum entanglement: Although millions of light-years away 2 related particles change their state at the same time. Means it takes zero time to 'communicate'. The only 'thing' that is faster than light takes zero time. Means the velocity is infinite.

Today marks the 50th anniversary of the Apollo moon landing. Hard to believe that this happened right after I graduated high school and we have yet to establish a permanent colony or base there. Maybe that will happen sometime before I die.
We may colonize Mars before we colonize the moon, Mars has a better (but not by much) atmosphere to colonize
Guys, You might see lunar colonization sooner if there's enough He3 on the Moon to warrant it. https://www.esa.int/Our_Activities/...h/Energy/Helium-3_mining_on_the_lunar_surface
I've heard that science states that an asteroid hit the earth at one time in it's early history and that is how we got our moon. If this is correct then the moon would have the same minerals as the Earth, including gold, silver and other rare metals and minerals.
