Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed. The discovery, published in Nature, was made possible thanks to the HiPERCAM instrument on the Gran Telescopio Canarias (GTC) at the Roque de los Muchachos Observatory in La Palma. A system of rings has been discovered around the dwarf planet Quaoar which is approximately half the size of Pluto and orbits the Sun beyond Neptune. The discovery

The Anatomical Pathology service of the Complejo Hospitalario Universitario de Canarias (HUC) and the Instituto de Astrofísica de Canarias (IAC) are partners in the development of a computer application adapting artificial intelligence tools used in astronomy to digitised images of human tissue. The project, called “Patolog-IA”, aims to speed up the interpretation of test results and the diagnosis of colorectal cancer. It is expected that it will also be useful for personalised medicine oriented to other kinds of cancer. Colorectal cancer is one of the most aggressive types of cancer and the

Some 40 women astronomers, engineers and technologists from the Instituto de Astrofísica de Canarias (IAC), from IACTEC and from other collaborating institutions are taking part in around ten initiatives to raise awareness of the important contribution of women in Science and to stimulate the interest of girls in scientific and technological careers. The activities are part of the celebrations of 11F, the International Day of Women and Girls in Science, and they will extend from February till June. Even though the percentage of women in scientific and technical careers has grown in recent
