Metals usually become less conductive as they get thinner. Niobium phosphide, however, is different. According to researchers at Stanford University, US, a very thin film of this non-crystalline topological semimetal conducts electricity better than copper even in non-crystalline films. This surprising result could aid the development of ultrathin low-resistivity wires for [...]

An international team of researchers has developed new analytical techniques that consider interactions between three or more regions of the brain – providing a more in-depth understanding of human brain activity than conventional analysis. Led by Andrea Santoro at the Neuro-X Institute in Geneva and Enrico Amico at the UK’s [...]

This webinar will detail recent efforts in proton exchange membrane-based low temperature electrolysis degradation, focused on losses due to simulated start-stop operation and anode catalyst layer redox transitions. Ex situ testing indicated that repeated redox cycling accelerates catalyst dissolution, due to near-surface reduction and the higher dissolution kinetics of metals [...]

Physicists at Penn State and Columbia University in the US say they have seen the “smoking gun” signature of an elusive quasiparticle predicted by theorists 16 years ago. Known as semi-Dirac fermions, the quasiparticles were spotted in a crystal of the topological semimetal ZrSiS and they have a peculiar property: [...]

NASA has confirmed that its Parker Solar Probe has survived its record-breaking closest approach to the solar surface. The incident occurred on 24 December where it flew some 6.1 million kilometres above the surface of the Sun – well within the orbit of Mercury. A “beacon tone” that was received [...]

This episode of the Physics World Weekly podcast explores how the concept of humanitarian engineering can be used to provide high quality cancer care to people in low- and middle-income countries (LMICs). This is an important challenge because today only 5% of global radiotherapy resources are located in LMICs, which [...]

Engineers have successfully integrated key parts of NASA’s $4bn Nancy Grace Roman Space Telescope marking a significant step towards completion.  The space agency has announced that the mission’s payload, which includes the telescope, two instruments and the instrument carrier, has been combined with the spacecraft that will deliver the observatory [...]

In a Salt Lake City museum, the Traveling Gallery of Fluid Motion invites visitors to connect art and science, as the famous Italian polymath did.[Physics 18, 4] Published Thu Jan 09, 2025 [...]

Yari Golden-Castaño first learned about the moon, planets, and space while her grandmother in Mexico, Barbarita, taught her how to read from an encyclopedia. Golden-Castaño had already earned the nickname “little astronaut” among her family because of an astronaut onesie that her mother dressed her in. By third grade, she [...]

Of all the unanswered questions in modern science, perhaps the most talked about is whether we are alone in the universe. A new paper looks at another way we might be able to detect advanced civilizations, and at its center is the need for energy. [...]

MIT physicists develop a predictive formula, based on bacterial communities, that may also apply to other types of ecosystems, including the human GI tract. When a new species is introduced into an ecosystem, it may succeed in establishing itself, or it may fail to gain a foothold and die out. Physicists [...]

A novel device now enables scientists to easily adjust the twist between layers of ultra-thin materials, promising significant advances in electronics and optics. This could lead to better transistors and solar cells, and enhance research in quantum computing. https://scitechdaily.com/meet-mega2d-the-tiny-machine-twisting-material-science-into-the-future/Pablo Jarillo-Herrero, The post Meet MEGA2D: The Tiny Machine Twisting Material Science into the [...]
