Nanopores and deep learning change disease diagnostics
Nanopores and deep learning change disease diagnostics
Scientists unveil a groundbreaking method using biological nanopores and deep learning to detect protein modifications, offering new avenues in disease diagnostics. Proteins, the workhorses of the cell, undergo various modifications after their synthesis. Because they can profoundly affect how a protein operates in the cell, these "post-translational modifications", or PTMs, are key in numerous biological processes.

AI program classifies objects in satellite images faster
An AI program can train neural networks, using just a handful of images, to rapidly characterize in satellite and drone data new objects like ocean debris, deforestation zones, urban areas and more. Images taken by drones and satellites give scientists a wealth of information. These snapshots provide crucial insight into the changes taking place on the Earth's surface, such as in animal populations, vegetation, debris floating on the ocean surface and glacier coverage.

Bridging light and electrons
Bridging light and electrons
Researchers at EPFL and Max Plank have merged nonlinear optics with electron microscopy, unlocking new capabilities in material studies and the control of electron beams. When light goes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of an entire field of study called "nonlinear optics", which is now integral to technological and scientific advances from laser development and optical frequency metrology, to gravitational wave astronomy and quantum information science.

Scientists measure the distance to stars by their music
A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near Universe. For most of us, the countless bright spots in the nighttime sky all seem to be stars.
