A novel method for directing mitochondria to specific cells could reshape how scientists approach diseases driven by cellular dysfunction. Scientists have unveiled a new way to deliver one of the cell’s most vital components exactly where it is needed. Led by Botond Roska at the Institute of Molecular and Clinical Ophthalmology Basel (IOB), the team […]

A study reconstructs the chemical composition of key molecules in stars by analyzing their infrared fingerprints. A PhD student has recreated a small portion of the Universe inside a laboratory setup, producing synthetic cosmic dust and offering new insight into how the chemical ingredients for life may have formed long before Earth existed. Linda Losurdo, […]

Researchers report that certain movement-related symptoms of Alzheimer’s disease may originate in the peripheral nervous system rather than the brain. Researchers at the University of Central Florida say some early movement problems linked to Alzheimer’s may begin outside the brain, raising new questions about where the disease starts and how soon it might be detected. […]

Cancer cells may “learn” to survive therapy by rewiring gene activity using AP-1 proteins. Researchers at NYU Langone Health say cancer cells may have a far more flexible survival system than scientists once thought. In a new model, the team argues that some tumors may not need to wait for rare DNA mutations to escape […]

A common sleep supplement may carry unexpected risks when used long-term. Melatonin has long been marketed as a gentle, “natural” way to improve sleep. But new research is raising questions about what happens when people rely on it for years. A large international analysis of more than 130,000 adults with chronic insomnia found that those […]
