The study, published in the Proceedings of the National Academy of Sciences, has the potential to transform treatment for this rare disease and may also have implications for more common diseases.
Retinal cells grown from stem cells can reach out and connect with neighbors, according to a new study, completing a “handshake” that may show the cells are ready for trials in humans with degenerative eye disorders.Over a decade ago, researchers from the University of Wisconsin–Madison developed a way to grow organized clusters of cells, called organoids, that resemble the retina, the light-sensitive tissue at the back of the eye.
Using the latest technologies—including both single-nuclear sequencing of mice and human liver tissue and advanced 3D glass imaging of mice to characterize key scar-producing liver cells—researchers have uncovered novel candidate drug targets for non-alcoholic fatty liver disease (NAFLD). The research was led by investigators at the Icahn School of Medicine at Mount Sinai. Utilizing these innovative methods, the investigators discovered a network of cell-to-cell communication driving scarring as liver disease advances. The findings, published online on January 4 in Science Translational Medicine, could lead to new treatments.
Orangutans, mice, and horses are covered with it, but humans aren’t. Why we have significantly less body hair than most other mammals has long remained a mystery. But a first-of-its-kind comparison of genetic codes from 62 animals is beginning to tell the story of how people—and other mammals—lost their locks.

For the first time, researchers at UC San Diego have shown that changes in gene expression happen almost entirely during the transcription stage while the cells are growing. The researchers have provided a simple quantitative formula linking regulatory control to mRNA and protein levels.
Scientists used patient stem cells and 3D bioprinting to produce eye tissue that will advance understanding of the mechanisms of blinding diseases. The research team from the National Eye Institute (NEI), part of the National Institutes of Health, printed a combination of cells that form the outer blood-retina barrier—eye tissue that supports the retina's light-sensing photoreceptors. The technique provides a theoretically unlimited supply of patient-derived tissue to study degenerative retinal diseases such as age-related macular degeneration (AMD).

One-hundred fifty years ago, Charles Darwin speculated that life likely originated in a warm little pond. There, Darwin supposed, chemical reactions and the odd lightning strike might have led to chains of amino acids that, over time, became more and more complex until the beginnings of life emerged.Ever since, researchers have investigated this type of pre-life or “prebiotic” chemistry, trying to figure out the chemical pathways that could have led from a pool filled with simple amino acids to bacteria, redwood trees and people.
Irvine, Calif., Dec. 21, 2022 — A research team led by the University of California, Irvine has linked the mutation that causes Huntington’s disease to developmental deficits in the brain’s oligodendrocyte cells that are caused by changes in metabolism. They found that high doses of thiamine and biotin can restore normal processes.
Researchers from Children’s Hospital of Philadelphia (CHOP) and New Jersey Institute of Technology (NJIT) developed new software that integrates a variety of information from a single cell, allowing researchers to see how one change in a cell can lead to several others and providing important clues for pinpointing the exact causes of genetic-based diseases.

Artificial intelligence could help doctors dynamically determine safe and effective medication dosing for unstable ICU patients. Predicting the right dose of medication that a critically ill child in the ICU will require in the future is a huge challenge for clinicians. FDA prescribing guidelines generally assume that patients are stable enough so that dosing for a given group is usually unchanged during treatment, but this ‘one size fits all’ approach to medication dosing does not accurately target the condition of each individual patient over time.
Jessica Thaxton’s group at the UNC School of Medicine found that T cells exposed to the environment of solid cancers undergo a natural response to stress that shuts off their function, limiting T cell ability to kill tumors.
Researchers from Boston Children’s Hospital and Harvard, using Argonne’s Advanced Photon Source, have characterized the structure of integrins, a type of cell surface receptor involved in the immune response.
Youth who underwent metabolic and bariatric surgery as teenagers are at heightened risk for alcohol use, according to the first study to document long-term alcohol use and associated issues in this population. Researchers found that after eight years, nearly half of study participants had alcohol use disorders, symptoms of alcohol-related harm, or alcohol-related problems. Results were published in the journal Annals of Surgery.
Researchers at UC San Diego provide new insights into the pathology of limbic predominate age-related TDP-43 encephalopathy, which mimics Alzheimer’s, making it very difficult to identify in living patients.
Cardiology researchers at Albert Einstein College of Medicine and Montefiore Health System have received a five-year, $5.2 million grant from the National Institutes of Health (NIH) to explore the underlying causes of heart failure among Hispanics/Latinos, who are at heightened risk for heart disease. Investigators will take a novel approach to assess risk: by simultaneously evaluating heart function and the relationship between the heart and the aorta, the large artery that conveys oxygen-rich blood from the heart’s left ventricle to the rest of the body.
Alzheimer’s disease (AD) is the fifth leading cause of death in adults over 65 years old. While many potential treatments for the neurodegenerative disease focus on developing drugs to target key culprits, a relatively new approach aims to more directly treat the brain.
The flight of insects may look effortless but, as with any animal, their movements would be wildly uneven without an intricate system of neural signaling and muscle response to stabilize and steer them.
