Scientists at the Institute for Basic Science (IBS) have uncovered a non-invasive method to boost the brain’s natural waste drainage system—a discovery that could open new avenues for tackling age-related neurological disorders.

In a study published in Nature, researchers from the IBS Center for Vascular Research, led by Director Koh Gou Young, along with senior researchers Jin Hokyung, Yoon Jin-Hui, and principal researcher Hong Seon Pyo, demonstrate that precisely stimulating the lymphatics under skin on the neck and face can significantly enhance the (CSF)—the liquid that cushions the brain and helps remove —through .

This offers a new approach to clearing brain waste using safe, non-invasive mechanical stimulation, rather than relying on drugs or surgical interventions.

Boise State University researchers have developed a new technique and platform to communicate with cells and help drive them toward cartilage formation. Their work leverages a 3D biocompatible form of carbon known as graphene foam and is featured on the cover of Applied Materials and Interfaces.

In this work, the researchers aim to develop new techniques and materials that can hopefully lead to new treatments for osteoarthritis through . Osteoarthritis is driven by the irreversible degradation of hyaline cartilage in the joints, which eventually leads to pain and disability, with complete joint replacement being the standard clinical treatment. Using custom-designed and 3D-printed bioreactors with electrical feedthroughs, they were able to deliver brief daily electrical impulses to cells being cultured on 3D graphene foam.

The researchers discovered that applying direct to ATDC5 cells adhered to the 3D graphene foam bioscaffolds significantly strengthens their and improves —key metrics for achieving lab-grown cartilage. ATDC5 cells are a murine chondrogenic progenitor cell line well studied as a model for cartilage tissue engineering.

A team at the University of California, Los Angeles has developed a low-cost diagnostic pen that converts handwriting into electrical signals for early detection of Parkinson’s disease, achieving 96.22% accuracy in a pilot study.

Parkinson’s disease impairs the , leading to tremors, stiffness, and slowed movements that impair fine motor functions such as . Clinical diagnosis today largely relies on subjective observations, which are prone to inconsistency and often inaccessible in . Biomarker-based diagnostics, while objective, remain constrained by cost and technical complexity.

In the study, “Neural network-assisted personalized handwriting analysis for Parkinson’s disease diagnostics,” published in Nature Chemical Engineering, researchers engineered a diagnostic pen to capture real-time motor signals during handwriting and convert them into quantifiable electrical outputs for disease classification.

Hearing aids, mouth guards, dental implants, and other highly tailored structures are often products of 3D printing. These structures are typically made via vat photopolymerization—a form of 3D printing that uses patterns of light to shape and solidify a resin, one layer at a time.

The process also involves printing structural supports from the same material to hold the product in place as it’s printed. Once a product is fully formed, the supports are removed manually and typically thrown out as unusable waste.

MIT engineers have found a way to bypass this last finishing step, in a way that could significantly speed up the 3D-printing process. They developed a resin that turns into two different kinds of solids, depending on the type of light that shines on it: Ultraviolet light cures the resin into an highly resilient solid, while visible light turns the same resin into a solid that is easily dissolvable in certain solvents.

Imagine getting a tattoo… that can track your health, location, or identity — and you don’t even need a device. Sounds like sci-fi? It’s real. Scientists have developed futuristic electronic tattoos that use special ink to monitor your body in real-time — from heart rate to hydration — and even transmit data without chips or batteries. But here’s the catch… could this breakthrough be the future of medicine? Or is it a step too close to surveillance under your skin?

Let’s explore how these tattoos work, what they can really do, and the wild implications they might have for your health — and your privacy.

For decades, we’ve thought the control center of life lies in DNA. But a new scientific framework is emerging that challenges that idea, and suggests that vast portions of the genome are immaterial and lie outside the physical world. Today, physicist Dr. Brian Miller shares his perspective on the cutting-edge, potentially revolutionary research of mathematical biologist Dr. Richard Sternberg on the immaterial aspects of the genome. In this exchange, Dr. Miller shares several examples of the immaterial nature of life. These ideas point towards the earliest stages of the next great scientific revolution and have significant implications for the intelligent design debate.
