Swiss scientists unveil ‘intelligent’ microscope using AI
September 12, 2022 -- Swiss scientists have automated microscope control for imaging biological events such as cell division all while limiting stress on the sample. The team from École Polytechnique Fédérale de Lausanne trained artificial neural networks to detect subtle cell events and use that information to drive changes in microscope acquisition speed.

New cryo-EM tool visualizes biomolecules at near-atomic level
September 8, 2022 -- German researchers have used cryo-electron microscopy (cryo-EM) to visualize biomolecules at the atomic level, combining cryo-EM with a method used in materials research to observe protein building blocks in their natural environment in a snap-frozen state. Read More
Link between ion channel and cholesterol in brain may lead to novel treatments for Alzheimer’s
September 8, 2022 -- Mechanical forces and tissue functions influence the morphology of the developing brain, according to University of California, Irvine researchers, who also discovered a direct link in neural stem cells between Piezo1 -- a mechanically-activated ion channel -- and intracellular cholesterol levels during neural development.

Stanford scientists create synthetic microbiome
September 8, 2022 -- Stanford University researchers built a complex and well-defined synthetic microbiome with 100 bacterial species that they successfully transplanted into mice. The creation of the synthetic microbiome means the scientists will be able to add, remove, and edit individual species so they may better comprehend the links between gut microbiome and health.
