9 D Universe

The first results from the Dark Energy Spectroscopic Instrument (DESI) are a cosmological bombshell, suggesting that the strength of dark energy has not remained constant throughout history. Instead, it appears to be weakening at the moment, and in the past it seems to have existed in an extreme form known [...]

At a conference in 2014, bioengineer Jeffrey Fredberg of Harvard University presented pictures of asthma cells. To most people, the images would have been indistinguishable – they all showed tightly packed layers of cells from the airways of people with asthma. But as a physicist, Lisa Manning saw something no [...]

Core physics This apple tree at Woolsthorpe Manor is believed to have been the inspiration for Isaac Newton. (Courtesy: Bs0u10e01/CC BY-SA 4.0) Physicists in the UK have drawn up plans for an International Year of Classical Physics (IYC) in 2027 – exactly three centuries after the death of Isaac Newton. Following [...]

A new artificial intelligence/machine learning method rapidly and accurately characterizes binary neutron star mergers based on the gravitational wave signature they produce. Though the method has not yet been tested on new mergers happening “live”, it could enable astronomers to make quicker estimates of properties such as the location of [...]

Waseem completed his DPhil in physics at the University of Oxford in the UK, where he worked on applied process-relational philosophy and employed string diagrams to study interpretations of quantum theory, constructor theory, wave-based logic, quantum computing and natural language processing. At Oxford, Waseem continues to teach mathematics and physics [...]

Disabled people in science must be recognised and given better support to help reverse the numbers of such people dropping out of science. That is the conclusion of a new report released today by the National Association of Disabled Staff Networks (NADSN). It also calls for funders to stop supporting [...]

Author(s): Daniele MarinazzoA new study of complex systems supports a growing trend that focuses more on analyzing a system’s collective behavior rather than on trying to uncover the underlying interaction mechanisms.[Physics 18, 71] Published Mon Mar 31, 2025 [...]

Neutron-activated gold Novel activation imaging technique enables real-time visualization of gold nanoparticles in the body without the use of external tracers. (Courtesy: Nanase Koshikawa from Waseda University) Gold nanoparticles are promising vehicles for targeted delivery of cancer drugs, offering biocompatibility plus a tendency to accumulate in tumours. To fully exploit their [...]

People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space. [...]

Aside from sunlight, the sun sends out a gusty stream of particles called the solar wind. The ESA-led Solar Orbiter mission is the first to capture on camera this wind flying out from the sun in a twisting, whirling motion. The solar wind particles spiral outward as if caught in [...]

At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf star. Its flare activity has been well-known to astronomers using visible wavelengths of light, but a new study using observations with the Atacama Large [...]

On the physics faculty for nearly 40 years and a member of the Center for Theoretical Physics, he focused on the interactions of hadrons and developed an R-matrix formulation of scattering theory. Earle Leonard Lomon PhD ’54, MIT professor emeritus of physics, died on March 7 in Newton, Massachusetts, at the [...]
