Emmanuel Macron stood in front of the masterpiece by Leonardo da Vinci as he made the announcement to an audience of dignitaries, with the change to be introduced by 2031 and visitors charged separately to see the painting. The French president was outlining his New Renaissance project, which will also involve an international competition to design a second entrance to relieve the growing pressure of visitor numbers beneath the famous glass Pyramid. Tariff changes will also be introduced from next January so non-EU residents - including UK tourists - pay more to visit. Getty Images Eve...

     From - Sky & Telescope  By - Bob King Edited by - Amal Udawatta    You can see how quickly the comet's head changed over just 3 nights, starting sharp and bright, then becoming more diffuse. The bright streak is a synchrone and comprised of dust particles released at the time the nucleus fragmented. Larger, heavier particles reside near the nucleus while smaller ones are pushed tailward by solar radiation pressure, creating the streak. Lionel Majzik The nucleus of Comet ATLAS (C/2024 G3) held together during a brutal perihelion but not for long. Lionel Majzik of Hungary was the first to report and record dramatic changes in the comet between January 18th and 19th. The bright, strongly condensed head rapidly became more diffuse, a sure sign that its nucleus was disintegrating based on past observations of crumbling comets. His superb sequence, photographed remotely from Chile, clearly reveal the dramatic transformation, which was later confirmed by ...

  From - BBC World News By -  David Cox Edited by - Amal Udawatta     Getty Images (Credit: Getty Images) A pioneering new treatment promises to tackle a wider range of cancers, with fewer side-effects than conventional radiotherapy. It also takes less than a second. In a series of vast underground caverns on the outskirts of Geneva, Switzerland, experiments are taking place which may one day lead to new generation of radiotherapy machines. The hope is that these devices could make it possible to  cure complex brain tumours ,  eliminate cancers that have metastasised  to distant organs, and generally  limit the toll  which cancer treatment exerts on the human body. The home of these experiments is the European Laboratory for Particle Physics (Cern), best known to the world as the particle physics hub that developed the Large Hadron Collider, a 27 kilometre (16.7 mile)-long ring of superconducting magnets capable of accelerating particles to n...
