Nominations are now open for the 3D Printing Industry Awards 2023. Who are the leaders in 3D printing? Find out on November 30th when the winners across twenty categories will be announced during a London-based live awards ceremony.
A team of scientists from the University of Sydney and the Children’s Medical Research Institute (CMRI) at Westmead have leveraged 3D photolithographic printing to fabricate functional human tissues that accurately mimic an organ’s architecture.
The researchers utilized bioengineering and cell culture techniques to instruct stem cells derived from blood cells and skin cells to become specialized. These specialized cells can then form organ-like structures.
On a drizzly afternoon, Yan Zhao pointed to the trees visible from his campus window.
As a chemistry professor at Iowa State University, he is pioneering the creation of novel synthetic catalysts that break down cellulose, the plant fibers responsible for the trees’ height and strength.
“Cellulose is built to last – a tree doesn’t just disappear after rain,” Zhao said. “Cellulose is a huge challenge to break down.”

Stimulating the brain with electricity has been used for 30 years to treat Parkinson’s disease. Now, researchers are testing whether it could help restore hand and arm motion.
• Encryption and segmentation: These operate on the assumption some fraction of the network is already compromised. Restricting the reach and utility of any captured data and accessible networks will mitigate the damage even on breached systems.
• SBOM documentation: Regulatory compliance can be driven by industry organizations and the government, but it will take time to establish standards. SBOM documentation is an essential foundation for best practices.
If “democracy dies in darkness,” and that includes lies of omission in reporting, then cybersecurity suffers the same fate with backdoors. The corollary is “don’t roll your own crypto” even if well-intentioned. The arguments for weakening encryption to make law enforcement easier falls demonstrably flat, with TETRA just the latest example. Secrets rarely stay that way forever, and sensitive data is more remotely accessible than at any time in history. Privacy and global security affect us all, and the existence of these single points of failure in our cybersecurity efforts are unsustainable and will have unforeseeable consequences. We need to innovate and evolve the internet away from this model to have durable security assurances.
After surgeons perform first womb transplant in UK, we look at other major advances through the years.
In a recent study published in the journal Frontiers in Medicine, researchers evaluated fluorescence optical imaging (FOI) as a method to accurately and rapidly diagnose rheumatic diseases of the hands.
They used machine learning algorithms to identify the minimum number of FOI features to differentiate between osteoarthritis (OA), rheumatoid arthritis (RA), and connective tissue disease (CTD). Of the 20 features identified as associated with the conditions, results indicate that reduced sets of features between five and 15 in number were sufficient to diagnose each of the diseases under study accurately.
That early experience drove his professional interest in helping people communicate.
Now, Henderson’s an author on one of two papers published Wednesday showing substantial advances toward enabling speech in people injured by stroke, accident or disease.
Although still very early in development, these so-called brain-computer interfaces are five times better than previous generations of the technology at “reading” brainwaves and translating them into synthesized speech. The successes suggest it will someday be possible to restore nearly normal communication ability to people like Henderson’s late father.
Human cells evolving in the laboratory undergo a series of predictable, sequential genetic changes that lead to pre-cancer. Blocking these changes may allow intervention before cancer occurs.
