Uncovering the secrets of some of the world's first color photographs
Researchers have shed new light on one of the earliest color photography techniques, G. Lippmann's Nobel Prize-winning multispectral imaging method. It is often said that before air travel our skies were bluer yet how, in the 21 st century, could we ever know what light and colors were like one hundred years ago? Recently, a group of researchers from EPFL's Audiovisual Communications Laboratory , in the School of Computer and Communication Sciences (IC), had a unique opportunity to try to find out.

Designing better antibody drugs with artificial intelligence
Machine learning methods help to optimise the development of antibody drugs. This leads to active substances with improved properties, also with regard to tolerability in the body. Antibodies are not only produced by our immune cells to fight viruses and other pathogens in the body. For a few decades now, medicine has also been using antibodies produced by biotechnology as drugs.

Using AI to Diagnose Neurological Diseases Based on Motor Impairment
New Heidelberg approach: analysing movement patterns through machine learning The way we move says a lot about the state of our brain. While normal motor behaviour points to a healthy brain function, deviations can indicate impairments owing to neurological diseases. The observation and evaluation of movement patterns is therefore part of basic research, and is likewise one of the most important instruments for non-invasive diagnostics in clinical applications.

Topological data analysis can help predict stock-market crashes
Topological data analysis can help predict stock-market crashes
Scientists, together with local startup L2F, have developed a robust model that can predict when a systemic shift is about to occur, based on methods from a branch of mathematics called topological data analysis. Topological data analysis (TDA) involves extracting information from clouds of data points and using the information to classify data, recognize patterns or predict trends, for example.

Big Data Accelerates Biodiversity Research
Carnegie Mellon University Museums hold the storehouse of specimens required to understand biodiversity across the planet. These archives serve as historical snapshots of biodiversity in one area, at one time. While this information has historically remained isolated, recent efforts to digitize collections have produced a bridge between these rich troves, combining collections into a larger pool that researchers can tap to tackle deep questions about global biodiversity.

A Touch of Silver
Carnegie Mellon University In the field of robotics, metals offer advantages like strength, durability and electrical conductivity. But, they are heavy and rigid - properties that are undesirable in soft and flexible systems for wearable computing and human-machine interfaces. Hydrogels, on the other hand, are lightweight, stretchable and biocompatible, making them excellent materials for contact lenses and tissue engineering scaffolding.

Artist’s intent: AI recognizes emotions in visual art
A team of AI researchers has trained its algorithms to see the emotional intent behind great works of art, possibly leading to computers that see much deeper than current technologies. Researchers have built an algorithm that can capture the emotions that an image evokes. Experts in artificial intelligence have gotten quite good at creating computers that can "see" the world around them - recognizing objects, animals, and activities within their purview.
