Scientists at University of Edinburgh discovers chain-melted state of matter

The scientists at University of Edinburgh have discovered a new state of physical matter – which allows atoms to exist as both solid and liquid at the same time. Until now, atoms in physical matter were understood to exist typically in one of three states — solid, liquid or gas. An international team of physicists ..

Astronomers capture first ever image of Black Hole

Astronomers have captured the first-ever image of a black hole, which is located in a distant galaxy known as ‘Messier 87’ (M87), through a network of 8 linked radio telescopes known as the Event Horizon Telescope (EHT) Collaboration. The black hole in the centre of M87 has a mass of more than six billion solar ..

MIT student creates an Algorithm that made first Black hole image

Computer scientist Katie Bouman, who is still a graduate student at MIT has developed the algorithm to create the first image ever of a black hole. Katie has named the algorithm ‘CHIRP’ (Continuous High-resolution Image Reconstruction using Patch priors) which was needed to gather data from 8 radio telescopes across the world working under Event Horizon ..

University of Wisconsin-Madison scientist develops a new pin-sized sensor that can detect dangerous chemicals

The scientists at the University of Wisconsin-Madison in the US have developed a novel sensor that can be used in smartphone-sized devices to detect dangerous chemicals based on a unique fingerprint of absorbed and emitted light. Devices called spectrometers are light-splitting instruments that have long been both bulky and expensive, preventing their use outside the ..

The scientists at University of Michigan find that cold plasma can kill 99.9% of airborne viruses

Scientists from University of Michigan in the United States have found that dangerous airborne viruses can be rendered harmless on-the-fly when exposed to ‘cold plasma’ – a stream of energetic, charged fragments of air molecules. The researchers have measured the virus-killing speed and effectiveness of non thermal plasmas – the ionised, or charged, particles that ..
