Scientists Destroy 99% of Cancer Cells in Lab Using Vibrating Molecules
Health25 December 2024 ByDavid Nield Illustration of a cancer cell. (Science Photo Library/Canva Pro) Scientists have discovered a remarkable way to destroy cancer cells. A study published last year found stimulating aminocyanine molecules with near-infrared light caused them to vibrate in sync, enough to break apart the membranes of cancer cells. Aminocyanine molecules are already used in bioimaging as synthetic dyes....

Allergic Contact Dermatitis: New Culprits
Stéphanie Lavaud December 19, 2024 023 New allergens responsible for contact dermatitis emerge regularly. During the Dermatology Days of Paris 2024 conference, Angèle Soria, MD, PhD, a dermatologist at Tenon Hospital in Paris, France, outlined four major categories driving this trend. Among them are (meth)acrylates found in nail cosmetics used in salons or do-it-yourself false nail kits...

TNF inhibitors prevent complications in kids with Crohn’s disease: Study recommends them as first-line therapies
by Sam Page, University of Michigan Credit: Kindel Media from Pexels Early treatment of pediatric Crohn’s disease with anti-tumor necrosis factor medications can substantially reduce the risk of perianal fistulas, a particularly debilitating complication of Crohn’s disease. Michigan Medicine researchers confirmed this finding using prospective data. The resulting paper, “Early tumour necrosis factor antagonist treatment prevents perianal fistula development...

Engineering a smile: Stem cell–based conduits restore facial nerve function in animal study
by National Institutes of Health Facial nerve injuries are often treated with tissue taken from a patient’s body, called autografts. Alternatively, researchers are developing engineered conduits which could potentially be more accessible. Credit: NIBIB. Created with BioRender.com A gesture as simple as a smile can often convey what words cannot. This is part of why nonverbal...

Engineered T cells could help patients overcome resistance to CAR T cell therapy
by City of Hope National Medical Center Engineering a leucine zipper-based cell-sorting system. Credit: Nature Biomedical Engineering (2024). DOI: 10.1038/s41551-024-01287-3 Physician-researchers with City of Hope have developed a way to add features to T cells to help them overcome mechanisms of chimeric antigen receptor (CAR) T cell therapy resistance. Their new system is outlined in a paper published in Nature Biomedical...

Reprogramming cells for heart repair: New method transforms ordinary fibroblasts into mature cardiomyocytes
by Korea University College of Medicine This diagram illustrates how the combination of fibroblast growth factor 4 and ascorbic acid activates the JAK2–STAT3 signaling pathway, promoting the maturation of induced cardiomyocytes (iCMs). This approach effectively reprograms fibroblasts into cardiomyocytes with improved structure and function, offering exciting possibilities for regenerative medicine.

Introducing perceptein, a protein-based artificial neural network in living cells
by Justin Jackson , Phys.org Here, each neuron is represented as spacecrafts, with their pilots in the cockpits depicted in the shape of protein 3D structures. These spacecrafts collectively process and transmit information to the final red neuron to make decisions on space navigation. The wires that connect the neurons, with the green substance inside,...
