DOI: 10.1016/j.stem.2023.12.009A team of University of Wisconsin–Madison scientists has developed the first 3D-printed brain tissue that can grow and function like typical brain tissue. It’s an achievement with important implications for scientists studying the brain and...
Gut bacteria can process dietary fiber into an anti-allergy weapon, finds new study
by Tokyo University of Science Gut bacteria break down dietary fiber into short-chain fatty acids, which are known to affect our immune system. In this study, researchers investigated in detail the mechanisms by which these compounds mediate the activation of mast cells.

Research finds risk of dementia nearly three times higher the first year after a stroke
by American Heart Association Credit: Pixabay/CC0 Public DomainHaving a stroke may significantly increase the risk of developing dementia. The risk of dementia was the highest in the first year after a stroke and remained elevated over a period of 20 years, according to preliminary research presented at the American Stroke Association’s International Stroke Conference 2024, held...
Researchers find new techniques to repair lung tissue after damage from flu and COVID-19
by Nathi Magubane, University of Pennsylvania Confocal imaging demonstrating the dense network of capillary blood vessels in the lung that allow oxygen to move into our bloodstream. This complex vascular network can be severely disrupted upon viral infections like influenza and COVID-19, which greatly contributes to disease severity and mortality.

FDA warns of dangerous counterfeit eyedrops
by Dennis Thompson Certain copycat eyedrops may be contaminated and could give users an antibiotic-resistant eye infection, the U.S. Food and Drug Administration warned Wednesday. The packaging for South Moon, Rebright and FivFivGo eyedrops mirrors the packaging for Bausch & Lomb’s Lumify eyedrops, an over-the-counter product approved for red eye relief. However, samples of the...
Study finds neuromodulation of the brain with ultrasound waves leads to braver behavior in situations of mental conflict
by University of Würzburg The TUS technique has the potential to safely target deeper areas of the brain even at low energies. The elliptical blue area shows its area of influence in the current study, the right prefrontal cortex. This area is associated with brain regions that produce the EEG parameter of the mid-frontal theta frequency,...
Tiny particles offer big clues toward predicting Alzheimer’s decades in advance
by Translational Genomics Research Institute Credit: Pixabay/CC0 Public DomainIn a study published in the journal, Cells, a team of scientists describe using machine learning models to identify changes in RNA molecules of plasma extracellular vesicles (EVs) that may hold potential for identifying Alzheimer’s disease (AD) at its earliest stages. EVs are tiny particles released by the...
Scientists discover a potential way to repair synapses damaged in Alzheimer’s disease
by Buck Institute for Research on Aging The art depicts the recovery of the functional plasticity at synapses on neurons despite tau-induced toxicity in the brain. Credit: Larissa BrownWhile newly approved drugs for Alzheimer’s show some promise for slowing the memory-robbing disease, the current treatments fall far short of being effective at regaining memory. What...
Light, labor inducer could treat skin condition vitiligo

DOI: 10.1038/s41467-024-45034-3Patients with an appearance-altering skin condition may have relief thanks to an unlikely cocktail of a molecule that induces labor, an immunosuppressant medication and controlled UVB irradiation. This College of...
New potential immunotherapies for pancreatic cancer
by Rush University Medical Center Neutralization of p402 and p40 increases levels of IFN-γ in pancreatic cancer cells. Immunohistochemical analysis at 60× magnification of PANC-1 (A) and BxPC-3 cells (B) treated with p40 homodimer or p40 monomer were labeled with IFN-γ (red). DAPI was used to stain the nuclei. Cells positive for IFN-γ were counted and...
