Spanish scientists have detected for the first time the magnetic state of a triangular structure of graphene with just 40 carbon atoms. The finding expands the possible applications of this material in information technology.
French scientists at the Neel Institute have produced a graphene patch that records the condition of chronic wounds, such as ulcers suffered by the elderly or those with diabetes, at any time. The data can be sent from home to the hospital via mobile phone, facilitating a rapid response to possible infections.
An artificial neural network has identified a square structure within a triangular one in a crater on the dwarf planet Ceres, with several people agreeing on this perception. The result of this intriguing visual experiment, carried out by a Spanish neuropsychologist, calls into question the application of artificial intelligence to the search for extra-terrestrial intelligence (SETI).
Ommochromes, the pigments that colour the skin of squids and other invertebrates, could be used in the food and health sectors for their antioxidant and antimicrobial properties. This is confirmed by the analyses carried out by researchers from the University of Sonora in Mexico and the Miguel Hernández University in Spain.
Seven European hospitals have validated a new methodology developed at Universitat Politècnica de València (UPV, Spain) to monitor patients with glioblastoma. This methodology helps medical doctors know the patients' situation with greater precision; it allows them to obtain several vascular biomarkers directly linked to their survival.
Whenever required to define the colours of an image, one usually falls back on a system of eleven well-known names, such as white, red, green and blue, but a team of Chinese and European scientists propose using an additional 28 terms, such as burgundy, salmon, lavender, plum, tan and olive green These new descriptors offer better results when it comes to classifying images, identifying people and visually monitoring individuals.
