Marking a significant advancement in medical technologies, a team of researchers from the Medical University of Vienna and Vienna University of Technology (TU Wien) has 3D printed the world’s first high-resolution brain.
Modeled after the structure of brain fibers, the 3D-printed “brain phantom” can be imaged with a specialized form of magnetic resonance imaging (MRI) known as dMRI.
March 14, 2024 – Detecting colorectal cancer may be as easy as a simple blood test one day.
Promising results of this new option — the results of the study were published this week in the New England Journal of Medicine — could help convert the estimated 1 in 3 people who don’t stay up-to-date on screenings that should begin at age 45. If everyone in the U.S. got screened regularly, as many as 90% of deaths linked to colorectal cancer may be avoided, the researchers wrote. Current screening options are often considered unpleasant experiences — collecting a fecal sample at home and mailing it, or taking laxatives and going under sedation for a colonoscopy procedure.
The blood test can detect DNA shed into the bloodstream from tumors, and in a trial of more than 7,800 people, the new test accurately detected colon cancer at early, treatable stages 87% of the time. The false-positive rate was 10%. The test was less successful at detecting advanced precancerous lesions, with just 13% being detected. In comparison, fecal tests are about 42% successful at early detection, and colonoscopies are up to 93% accurate, according to a summary from the American College of Surgeons.

Is aging a disease that can be cured? Neil deGrasse Tyson and cohosts Chuck Nice and Gary O’Reilly discover the field of epigenetics, the Information Theory of Aging, and curing blindness for mice with Professor of Genetics at Harvard Medical School, David Sinclair.
What is epigenetics? Discover the difference between genetics and epigenetics. We discuss whether aging is a disease and if there have been any changes in aging throughout the centuries. David breaks down the information theory of aging and how epigenetic inheritance works. Plus, Chuck tells us about some of the studies he’s reading and how behaviors during your lifetime can be epigenetically passed onto your children.
Could we someday cure death? What does aging look like in the broader animal kingdom? We look at aging from an evolutionary standpoint, restoring vision in blind mice, and what the length of your telomeres tells you. We break down conflicting information regarding diet and how to not just live longer but live younger, longer. What are the genes that control aging?
We break down what anti-aging medicine would look like and whether it would be affordable for everyday people. Learn about the world’s oldest mice with the youngest eyes. We discuss the Yamanaka genes and how they can be utilized to turn back time on a cellular level. Is DNA destiny?

Elon Musk’s Neuralink recently implanted a chip in a human for the first time. The emerging market of brain computer interfaces, or BCIs, is in the process of finding its footing. In a world where AI is on the rise, BCIs allow for telepathic control of computers and wireless operation of prosthetics. But how does this tech work?
WSJ goes inside a brain surgery to see how the implants work, and breaks down what it’s going to take to get these devices on the market.

The first person with Neuralink’s computer-linked chip implanted in the surface of their brain showed off their “telekinetic” online chess-playing skills while discussing the “life-changing” procedure for the first time in a surprise livestream.
Noland Arbaugh, a 29-year-old with quadriplegia (or paralysis that affects the body from the neck down), volunteered to have the device implanted as part of Neuralink’s ongoing trial of the technology. Until now, his identity had remained a closely guarded secret.
THURSDAY, March 21, 2024 (HealthDay News) — A germ commonly found in the human mouth can travel to colon tumors and appears to speed their growth, new research shows.
The finding might lead to new insights into fighting colon cancer, which kills more than 52,000 Americans each year, according to the American Cancer Society.
Researchers at the Fred Hutchinson Cancer Center in Seattle looked at levels of a particular oral bacterium, Fusobacterium nucleatum, in colon tumor tissues taken from 200 colon cancer patients.
In the last decade, the advances made into the reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) led to great improvements towards their use as models of diseases. In particular, in the field of neurodegenerative diseases, iPSCs technology allowed to culture in vitro all types of patient-specific neural cells, facilitating not only the investigation of diseases’ etiopathology, but also the testing of new drugs and cell therapies, leading to the innovative concept of personalized medicine. Moreover, iPSCs can be differentiated and organized into 3D organoids, providing a tool which mimics the complexity of the brain’s architecture. Furthermore, recent developments in 3D bioprinting allowed the study of physiological cell-to-cell interactions, given by a combination of several biomaterials, scaffolds, and cells.
