Peter Higgs, pivotal in the discovery of the “God Particle,” has died at the age of 94. His groundbreaking work, for which he received a Nobel Prize, laid the foundation for understanding the universe’s fundamental structure and continues to guide current and future research in particle physics.

Peter Higgs has passed away at the age of 94. An iconic figure in modern science, Higgs in 1964 postulated the existence of the eponymous Higgs boson. Its discovery at CERN in 2012 was the crowning achievement of the Standard Model ℠ of particle physics – a remarkable theory that explains the visible universe at the most fundamental level.

Alongside Robert Brout and François Englert, and building on the work of a generation of physicists, Higgs postulated the existence of the Brout-Englert-Higgs (BEH) field. Alone among known fundamental fields, the BEH field is “turned on” throughout the universe, rather than flickering in and out of existence and remaining localized. Its existence allowed matter to form in the early universe some 10^-11 s after the Big Bang, thanks to the interactions between elementary particles (such as electrons and quarks) and the ever-present BEH field. Higgs and Englert were awarded the Nobel Prize for physics in 2013 in recognition of these achievements.

Pollsters trying to predict presidential election results and physicists searching for distant exoplanets have at least one thing in common: They often use a tried-and-true scientific technique called Bayesian inference.

Bayesian inference allows these scientists to effectively estimate some unknown parameter — like the winner of an election — from data such as poll results. But Bayesian inference can be slow, sometimes consuming weeks or even months of computation time or requiring a researcher to spend hours deriving tedious equations by hand.

Amplified Industries, founded by Sebastien Mannai, helps oil field operators eliminate spills and stop methane leaks.

There is a staggeringly long list of things that can go wrong during the complex operation of an oil field.

Study shows neutrons can bind to nanoscale atomic clusters known as quantum dots. The finding may provide insights into material properties and quantum effects.

Neutrons are subatomic particles that have no electric charge, unlike protons and electrons. That means that while the electromagnetic force is responsible for most of the interactions between radiation and materials, neutrons are essentially immune to that force.

Rice University physicists have discovered a phase-changing quantum material — and a method for finding more like it — that could potentially be used to create flash-like memory capable of storing quantum bits of information, or qubits, even when a quantum computer is powered down.

Phase-Changing Materials and Digital Memory

Phase-changing materials have been used in commercially available non-volatile digital memory. In rewritable DVDs, for example, a laser is used to heat minute bits of material that cools to form either crystals or amorphous clumps. Two phases of the material, which have very different optical properties, are used to store the ones and zeros of digital bits of information.

Dr. Jackie Faherty: “Methane emission was not on my radar when we started this project but now that we know it can be there and the explanation for it so enticing I am constantly on the look-out for it. That’s part of how science moves forward.”

Brown dwarfs are too large to be considered planets and too small to produce nuclear fusion like stars. But can they still exhibit some of the same characteristics as planets, like aurorae? This is what a recent study published in Nature hopes to address as a team of international researchers investigated how the brown dwarf W1935, which is located approximately 47 light-years from Earth, could not only possess methane but also have aurorae, all of which are observed on Earth, Jupiter, and Saturn. This study holds the potential to help astronomers better understand the formation and evolution of brown dwarfs, as brown dwarfs remain some of the most mysterious objects in the cosmos despite thousands being identified.

For the study, the researchers used NASA’s James Webb Space Telescope (JWST) and its powerful infrared instruments to observe 12 brown dwarfs, including W1935. In the end, JWST observed strong evidence for the existence of methane with W1935, which the researchers compared to atmospheric models to confirm these findings, along with methane existing on Jupiter, Saturn, and Earth.
