Atoms transferred between optical tweezers via quantum tunneling in a first

Posted by in categories: 3D printing, bioprinting, biotech/medical, quantum physics

Researchers at the University of Twente, Netherlands, have made an advancement in bioprinting technology that could transform how we create vascularized tissues. Their innovative bioink, recently featured in Advanced Healthcare Materials, introduces a way to precisely guide the growth and organization of tiny blood vessels within 3D-bioprinted tissues. The tiny blood vessels mimic the intricate networks found in the human body.

3D-printed organs have the potential to revolutionize medicine by providing solutions for organ failure, and tissue damage and developing new therapies. But a major challenge is ensuring these printed tissues receive enough nutrients and oxygen, which is critical for their survival and function. Without blood vessels, these tissues can’t efficiently obtain nutrients or remove waste, limiting their effectiveness. Therefore, the ability to 3D-bioprint blood vessels is a crucial advancement.

Tissue engineers could already position blood vessels during the bioprinting process, but these vessels often remodel unpredictably when cultured in the lab or implanted in the body, reducing the effectiveness of the engineered tissue. The programmable bioink developed by the University of Twente team addresses this issue by providing dynamic control over vessel growth and remodeling over time. This opens new possibilities for creating engineered tissues with long-term functionality and adaptability.

Revolutionary High-Speed 3D Bioprinter hailed a Gamechanger for Drug Discovery

Posted by in categories: 3D printing, bioprinting, biotech/medical, neuroscience

Biomedical engineers from the University of Melbourne have invented a 3D printing system, or bioprinter, capable of fabricating structures that closely mimic the diverse tissues in the human body, from soft brain tissue to harder materials like cartilage and bone.

This cutting-edge technology offers cancer researchers an advanced tool for replicating specific organs and tissues, significantly improving the potential to predict and develop new pharmaceutical therapies. This would pave the way for more advanced and ethical drug discovery by reducing the need for animal testing.

Head of the Collins BioMicrosystems Laboratory at the University of Melbourne, Associate Professor David Collins said: In addition to drastically improving print speed, our approach enables a degree of cell positioning within printed tissues. Incorrect cell positioning is a big reason most 3D bioprinters fail to produce structures that accurately represent human tissue.

Voxel building blocks for bioprinting human-compatible organs

Posted by in categories: bioprinting, biotech/medical, chemistry, engineering

A research team at the University of Virginia School of Engineering and Applied Science has developed what it believes could be the template for the first building blocks for human-compatible organs printed on demand.

Liheng Cai, an assistant professor of materials science and engineering and chemical engineering, and his Ph.D. student, Jinchang Zhu, have made biomaterials with controlled mechanical properties matching those of various human tissues.

“That’s a big leap compared to existing bioprinting technologies,” Zhu said.

When We’re Overly Optimistic about the Pace of Life Extension Research

Posted by in categories: 3D printing, bioprinting, biotech/medical, genetics, life extension, transhumanism

I have a new essay out via the wonderful site Merion West. The article is based on some of my experimental writings at Oxford. I hope you’ll read and consider it. I’m highly worried life extension science isn’t moving forward fast enough!


“Sadly, biological humans are likely to be mortal for centuries more, unless a dramatic increase of both resources and life extension scientists are marshaled.”

Certain well-known gerontologists and longevity experts around the world believe that sometime in this century—probably in the next 15–50 years—medicine will likely overcome and cure most forms of disease, and even death itself. Billionaires such as Meta’s Mark Zuckerberg, Amazon’s Jeff Bezos, Alphabet’s Larry Page, and Oracle’s Larry Ellison have jumped on board, pledging billions of dollars to “conquering all disease by this century” and mortality altogether.

Advanced Tech and Life Science on Station Today Promoting Health

Posted by in categories: 3D printing, bioprinting, biotech/medical, health, nanotechnology, science, space travel

Nanomaterials manufacturing, 3D bioprinting, and astronaut eye health were the main research topics aboard the International Space Station on Friday. The Expedition 71 crew members also continued servicing spacesuits and conducted an emergency drill.

The SpaceX Dragon cargo spacecraft recently delivered to the orbital outpost a biotechnology study to demonstrate the in-space production of nanomaterials that mimic DNA. NASA Flight Engineers Jeanette Epps and Mike Barratt worked on the second portion of that experiment on Thursday mixing then treating the research samples for analysis. Epps began her day mixing solutions in the Life Science Glovebox to create specialized nanomaterials. During the afternoon, Barratt applied sound and light treatments to the samples then stowed them aboard Dragon for analysis back on Earth. Results may lead to advanced therapies for space-caused and Earthbound health conditions.

The duo partnered back together at the end of the day for eye scans using standard medical imaging gear found in an optometrist’s on Earth. Barratt operated the hardware with guidance from doctors on the ground peering into Epp’s eyes and examining her retina and optic nerve for the B Complex eye health investigation.
