A new frequency-based analysis of recordings from neurons in the brain may give insight into brain pathologies such as Parkinson’s disease.

Research from Yale School of Medicine indicates a strong link between air pollution levels and eczema prevalence in the U.S.

The study found that residents in high PM_2.5 areas are twice as likely to develop eczema, suggesting significant health implications of air pollution on skin conditions.

A new study published today, November 13, 2024, in the journal PLOS ONE has found that people living in areas with higher air pollution are more likely to have eczema. Led by Dr. Jeffrey Cohen of Yale School of Medicine, the study explores the potential environmental impact of industrialization on skin health.

Researchers at the University of Minnesota have developed a new material poised to revolutionize the next generation of high-power electronics, making them faster, more transparent, and more efficient. This engineered material enables electrons to move at higher speeds while staying transparent to both visible and ultraviolet light, surpassing previous performance records.

The research, published in Science Advances, a peer-reviewed scientific journal, marks a significant leap forward in semiconductor design, which is crucial to a trillion-dollar global industry expected to continue growing as digital technologies expand.

Semiconductors power nearly all electronics, from smartphones to medical devices. A key to advancing these technologies lies in improving what scientists refer to as “ultra-wide band gap” materials. These materials can conduct electricity efficiently even under extreme conditions. Ultra-wide band gap semiconductors enable high-performance at elevated temperatures, making them essential for more durable and robust electronics.

There is a challenge related to prostate cancer from cancer cells that form resistance to treatments as the disease progresses. For medical science, these resistance mechanisms are not yet fully understood.

A new study by the University of Eastern Finland has filled some of this knowledge gap. The scientists found that inflammation-promoting immune cells, M1 macrophages, can transform cancer cells into stem-like cells and thus immune to treatment.

The study examined the impact of factors promoting inflammation in a tumour microenvironment on the progression of prostate cancer. Researchers focused particularly on the role of M1 and M2 macrophages in the tumour microenvironment. Macrophages are immune cells whose large number in the tumour area is often a sign of poor prognosis in relation to prostate cancer. These white blood cells stimulate the action of other immune system cells.

Summary: A recent study offers new insights into how brain regions coordinate during rest, using resting-state fMRI (rsfMRI) and neural recordings in mice. By comparing blood flow patterns with direct neural activity, researchers found that some brain activity remains “invisible” in traditional rsfMRI scans. This hidden activity suggests that current brain imaging techniques may miss key elements of neural behavior.

The findings, potentially applicable to human studies, may refine our understanding of brain networks. Further research could improve the accuracy of interpreting brain activity.

This study explores how muscle contractions, such as those that occur during exercise, influence motor neurons—the cells responsible for controlling muscle movement.

There’s no doubt that exercise does a body good. Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system.

Now, MIT engineers have found that exercise can also have benefits at the level of individual neurons. They observed that when muscles contract during exercise, they release a soup of biochemical signals called myokines.

Embracing the paradigm shift of agentic AI could lead to massive advancements in healthcare as we know it.

A genomic test developed at UC San Francisco to rapidly detect almost any kind of pathogen—virus, bacteria, fungus or parasite—has proved successful after a decade of use.

The test has the potential to vastly improve care for neurological infections that cause diseases like meningitis and encephalitis, as well as speed up the detection of new viral pandemic threats. It uses a powerful genomic sequencing technique, called metagenomic next-generation sequencing (mNGS).

Rather than looking for one type of pathogen at a time, mNGS analyzes all the nucleic acids, RNA and DNA, that are present in a sample.

Researchers caution that this is not an approach that should be emulated by others.
