Ghostly ‘mirror world’ might be cause of cosmic controversy

New research suggests an unseen 'mirror world' of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today -- the Hubble constant problem. The Hubble constant is the... Continue Reading →

OTD

On This Day 1968, Lise Meitner, born November 7, 1878, Vienna, Austria-Hungary [now in Austria] died.Austrian-born physicist who shared the Enrico Fermi Award (1966) with the chemists Otto Hahn and Fritz Strassmann for their joint research that led to the discovery of uranium fission. After receiving her doctorate at... Continue Reading →

New clues to why there’s so little antimatter in the universe

Imagine a dust particle in a storm cloud, and you can get an idea of a neutron's insignificance compared to the magnitude of the molecule it inhabits. But just as a dust mote might affect a cloud's track, a neutron... Continue Reading →

Researchers uncover how cells control the physical state of embryonic tissues

In the earliest stage of life, animals undergo some of their most spectacular physical transformations. Once merely blobs of dividing cells, they begin to rearrange themselves into their more characteristic forms, be they fish, birds or humans. Understanding how cells... Continue Reading →

New quantum receiver the first to detect entire radio frequency spectrum

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare. Army researchers built the quantum sensor, which can sample the radio-frequency spectrum—from zero frequency up to... Continue Reading →

Strongest evidence yet that neutrinos explain how the universe exists

New data throws more support behind the theory that neutrinos are the reason the universe is dominated by matter. The current laws of physics do not explain why matter persists over antimatter -- why the universe is made of 'stuff'.... Continue Reading →

Ultraviolet LEDs prove effective in eliminating coronavirus from surfaces and, potentially, air and water

As COVID-19 continues to ravage global populations, the world is singularly focused on finding ways to battle the novel coronavirus. That includes the UC Santa Barbara's Solid State Lighting & Energy Electronics Center (SSLEEC) and member companies. Researchers there are... Continue Reading →

ESO telescope sees star dance around supermassive black hole, proves Einstein right

Observations made with ESO's Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein's general theory of relativity. Its... Continue Reading →

Why is there any matter in the universe at all? New study sheds light

Scientists at the University of Sussex have measured a property of the neutron -- a fundamental particle in the universe -- more precisely than ever before. Their research is part of an investigation into why there is matter left over... Continue Reading →
