Electron neutrinos have been experimentally observed for the first time during recent experiments by physicists at CERN, which produced proton-proton collisions at the facility’s Large Hadron Collider (LHC). Neutrinos are neutral subatomic particles possessing almost no mass. First detected in 1956, they possess 1/2 integral spin like all fermions and rarely react with normal matter except through the weak force. Neutrinos come in three different varieties, associated with electrons, muons, and tau particles. Due to their sparring interactions with matter, all three types of neutrinos are regarded as being among the most elusive particles in the universe. Despite this, physicists...

A Hamiltonian cycle. © The University of Bristol =================================================================== A team of physicists has created a maze that they claim is the most difficult, using a pattern from the game of chess to make the structure. To the untrained eye, the maze looks like the most complicated snowflake. But to the puzzle-lovers among us, it probably looks like a challenge. The maze is constructed from a Hamiltonian cycle, a graph cycle that visits each node on the graph just once. The same pattern of movement is on display in the “Knight’s tour” in chess, by which the chess piece can...

In its first year, the Biden administration launched a fast-track Scientific Integrity Task Force, intended to “lift up the voices of Federal scientists of many perspectives and backgrounds” and put scientific integrity “paramount in Federal governance for years to come.” The task force took a “whole-of-government” approach to ensuring the scientific integrity of federally funded research and included representatives from the 21 federal agencies that maintain scientific-research programs. For those with a high pain threshold, the final report may be seen here. Prominent among the move’s critics have been the Council on Governmental Relations (a consortium of research universities) and...

Recent high school graduate Suborno Isaac Bari, 12, plans to start studying math and physics at New York University in the fall, but he's already got his ambitious sights set on beginning a doctoral program. "I hope to graduate college at 14 in spring 2026," said Suborno, who recently became the youngest graduate from his Long Island high school.

One of the surprising discoveries of the Webb telescope involves an early population of compact red galaxies at redshift above 7, a time when the Universe was 20 times younger than it is today. The galaxies are redder than expected from their cosmological redshift, indicating additional reddening by a layer of dust. Some of these galaxies contain as much mass in evolved stars as our own Milky Way galaxy. Nevertheless, they are a hundred times smaller in radius, of an order of a few hundred light years. These compact galaxies manifest an increase by a factor of a million in...

A recent study that presents new challenges to the existence of dark matter suggests gravity may be able to exist even in the absence of mass. Although all life on Earth experiences its effects daily, gravity remains one of the great mysteries of modern physics. Now, a new study published by Dr. Richard Lieu with The University of Alabama in Huntsville (UAH) proposes that the gravitational effects observed in galaxies and clusters may be the result of what he likens to topological defects in the universe, a theory that does not require the inclusion of dark matter to explain phenomena...

When astronomers turn our radio telescopes out towards space, we sometimes detect sporadic bursts of radio waves originating from across the vast expanse of the universe. We call them “radio transients”: some erupt only once, never to be seen again, and others flicker on and off in predictable patterns. We think most radio transients come from rotating neutron stars known as pulsars, which emit regular flashes of radio waves, like cosmic lighthouses. Typically, these neutron stars spin at incredible speeds, taking mere seconds or even a fraction of a second to complete each rotation. Recently, we discovered a radio transient...

Although Thomas Edison was awarded 2,332 worldwide patents as an inventor, one of his lasting contributions to modern society was not proprietary: the job interview. Edison was not just a prolific inventor — he was also a businessman in charge of an industrial empire. His corporation, Thomas A. Edison, Inc., employed more than 10,000 workers at dozens of companies. Edison wanted employees who could memorize large quantities of information and also make efficient business decisions. To find them, he devised an extensive questionnaire to assess job candidates’ knowledge and personality.Edison began using tests for candidate assessment in the late 19th...
