SOCIAL Mathematicians discover pattern that never repeats. Computer scientists discovered a new tile dubbed "einstein" after decades of trying. It is one shape, with 13 sides, that can cover an entire plane without ever repeating a pattern. The type of shape, known an "aperiodic monotile", is a shape that has real-world applications in material science. Astronomers detect rare 'ultramassive' black hole, about 33 billion times the mass of the Sun. Astronomers making use of a phenomenon known as gravitational lensing have discovered a black hole about 33 billion times the mass of the Sun, close to the upper limit of how large scientists believe they can be. Rapidly melting Antarctic ice could affect oceans for centuries. Scientists have warned that deep ocean water flows from the Antarctic could decline by 40% by 2050, threatening the collapse of circulation crucial for planetary systems. This would affect the global climate, the marine food chain, and even the stability of ice shelves. China tackles chip talent shortage with new courses and higher pay. China is ramping up efforts to develop home-grown semiconductor talent as it seeks to rapidly fill a shortage of expertise, made worse by US efforts to limit Beijing's access to advanced chip technology. Chile detects first case of bird flu in a human. Chile detected the first case of bird flu in a human, the country's health ministry reported.
