Summary: A new study reveals how AI-driven deep learning models can decode the genetic regulatory switches that define brain cell types across species. By analyzing human, mouse, and chicken brains, researchers found that some brain cell types remain highly conserved over 320 million years, while others have evolved uniquely.

This regulatory code not only sheds light on brain evolution but also provides new tools for studying gene regulation in health and disease. The findings highlight how AI can identify preserved and divergent genetic instructions controlling brain function across species.

The study also has implications for understanding neurological disorders by linking genetic variants to cognitive traits. Researchers are now expanding their models to study the brains of various animals and human disease states like Parkinson’s.

A major cybersecurity incident has exposed sensitive personal, medical and financial records of more than half a million Americans.

In a data breach notification, the Office of the Maine Attorney General says the California-based non-profit organization NorthBay Healthcare Corporation experienced an external system breach affecting 569,012 Americans.

In a notice sent to affected people, NorthBay Health says an unauthorized entity gained access to the firm’s computer systems between January 11th, 2024 and April 1st of the same year.

A team of Chinese scientists has used targeted gene editing to develop rice that produces coenzyme Q10 (CoQ10), a vital compound for human health.

Led by Prof. Chen Xiaoya from the CAS Center for Excellence in Molecular Plant Sciences/Shanghai Chenshan Research Center and Prof. Gao Caixia from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS), the researchers used targeted gene editing to modify just five amino acids of the Coq1 rice enzyme, creating new rice varieties capable of synthesizing CoQ10.

The study is published in Cell.

Researchers from Mass General Brigham and collaborating institutions have developed a non-invasive approach to manipulate cardiac tissue activity by using light to stimulate an innovative ink incorporated into bioprinted tissue. Their goal is to develop a technique that can be used to repair the heart. Their findings in preclinical models, published in Science Advances, show the transformative potential of non-invasive therapeutic methods to control electrically active tissues.

“We showed for the first time that with this optoelectronically active ink, we can print scaffolds that allow remote control of engineered heart tissues,” said co-corresponding author Y. Shrike Zhang, Ph.D., of the Division of Engineering in Medicine at Brigham and Women’s Hospital, a founding member of the Mass General Brigham health care system. “This approach paves the way for non-invasive light stimulation, tissue regeneration, and host integration capabilities in cardiac therapy and beyond.”

Three-dimensional bioprinted tissues composed of cells and other body-compatible materials are a powerful emerging tool to repair damaged heart tissue. But most bioprinted tissues cannot generate the necessary electrical activity for cellular function. They must instead rely on invasive wire and electrode placement to control heart activity, which can damage body tissues.

Divorce, the legal dissolution of marriage, can be driven by a variety of factors, ranging from changes in the economic status or health conditions of spouses to contrasting values. The end of a marriage can often be challenging to process. Thus, it can have adverse effects on the well-being and mental health of ex-spouses.

On average, the rates of worldwide have increased over the past century. Improved understanding of the primary factors that prompt people to dissolve a marriage could help to devise more effective couples and marriage counseling strategies, potentially contributing to a reduction in divorce rates.

Sari Mentser and Lilach Sagiv, two researchers at the Hebrew University of Jerusalem, recently carried out a study specifically exploring the relationship between people’s values and divorce. Their findings, published in Communications Psychology, suggest that interaction between spouses’ cultural and can predict divorce.

Synthetic biologists from Yale successfully rewrote the genetic code of an organism—a novel genomically recoded organism (GRO) with a single stop codon—using a cellular platform they developed that enables the production of new classes of synthetic proteins. Researchers say these synthetic proteins offer the promise of innumerable medical and industrial applications that can benefit society and human health.

A new study published in the journal Nature describes the creation of the landmark GRO, known as “Ochre,” which fully compresses redundant (or “degenerate”) codons into a single codon. A codon is a sequence of three nucleotides in DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Three studies at the University of Zurich demonstrate that hypnosis alters activity in the large-scale functional networks of the brain. It also affects the neurochemical milieu of specific brain areas.

Hypnosis has so far been something of a black box from the scientific perspective. Up to now, we have not had the data to prove whether hypnosis really is an extraordinary state of human consciousness, or simply in the subject’s imagination. Yet it remains a topic of fascination for many.

A well-known women’s magazine recently dedicated an entire dossier to hypnosis. And now and again we’ll hear of a remarkable hypnosis success story. For example, in 2018 at the Hirslanden Klinik St. Anna in Lucerne, a 45-year-old man had a metal plate removed from his lower arm under hypnosis only, without any anesthetic or . Much to the amazement of the surgical team, the man did not experience any significant pain either during or after the operation, as the Swiss public broadcaster SRF Puls health magazine program reported on 17 September of that year.

Researchers have achieved a breakthrough in wearable health technology by developing a novel self-healing electronic skin (E-Skin) that repairs itself in seconds after damage. This could potentially transform the landscape of personal health monitoring.

In a study published in Science Advances, scientists demonstrate an unprecedented advancement in E-Skin technology that recovers over 80% of its functionality within 10 seconds of being damaged—a dramatic improvement over existing technologies that can take minutes or hours to heal.

The technology seamlessly combines ultra-rapid self-healing capabilities, reliable performance in , advanced artificial intelligence integration, and highly accurate health monitoring systems. This integration enables real-time fatigue detection and muscle strength assessment with remarkable precision.
