5d ago
Late last year the Particle Physics Project Prioritization Panel ( P5) released a report that looks to the future of particle physics in the United States. The report is called Exploring the Quantum Universe and one of its authors, Abigail Vieregg, is our guest in this episode of the Physics World Weekly podcast. Vieregg is an astrophysicist and cosmologist at the University of Chicago and she talks about future experiments that P5 has recommended including a muon collider that could search for new physics on a much smaller footprint than conventional colliders. Vieregg also chats about the pr ..read more

Bionic jellyfish and more efficient windfarms: a conversation with John Dabiri
Physics World Weekly Podcast
by Physics World
1w ago
Jellyfish have a very simple, yet very effective way of swimming – and this has attracted the attention of the aeronautics engineer John Dabiri at the California Institute of Technology. In this episode of the Physics World Weekly podcast, Dabiri talks about his work on the artificial enhancement of jellyfish. He also explains how fluid dynamics can be used to boost the efficiency of windfarms, and explores the possibility that swimming organisms play important role in the mixing of the oceans. Dabiri and Caltech’s Simon Anuszczyk describe their bionic jellyfish in a paper that has been accept ..read more

Hydrogen can be used as a carbon-free source of energy in a wide range of applications including home heating, transportation and industry. However, there are significant challenges that must be overcome to ensure the safe and efficient storage and transportation of the gas. In this episode of the Physics World Weekly podcast, the materials expert Krzysztof Koziol explains why he is developing graphene-based materials and polymers to facilitate a hydrogen economy. Based at the UK’s Cranfield University, he chats about how existing national infrastructure for distributing natural gas can be ret ..read more

MRI keeps proton beam therapy on target, new technique tracks bacteria motion
Physics World Weekly Podcast
by Physics World
3w ago
Magnetic resonance imaging (MRI) and proton beam therapy are two powerful techniques of medical physics. The former gives us real-time images of internal structures of the body, and the latter can deliver a high dose of radiation to a tumour while reducing the damage to surrounding healthy tissue. In this episode of the Physics World Weekly podcast, the medical physicist Aswin Hoffmann talks about a research initiative in Germany that is combining the two techniques to achieve high-precision radiation therapy. The work is being done at the Center for Innovation in Radiation Oncology (OncoRay ..read more

The Magellanic Clouds: astronomers make the case for a name change
Physics World Weekly Podcast
by Physics World
1M ago
The Magellanic Clouds are prominent features of the southern sky that are named after the Portuguese explorer Ferdinand Magellan. He sailed west from Europe to the Philippines in the early 16th century and the clouds were described by a returning crew member. Voyages such as Magellan’s set into motion the European colonization of much of the world. This involved the oppression and assimilation of indigenous peoples and led to racism and inequality that endures to this day. In this episode of the Physics World Weekly podcast the astronomers Mia de los Reyes and Sally Oey explain why it is time ..read more

Company uses quantum optics to generate sequences of truly random numbers
Physics World Weekly Podcast
by Physics World
1M ago
Random numbers are used in several important technologies including cryptography and numerical simulation. However, large sequences of truly random numbers are notoriously difficult to generate – and correlations lurking within sequences can have dire consequences. Quantum systems are inherently random, so they offer a way to generate random numbers. In this episode of the Physics World Weekly podcast, our guest is Ramy Shelbaya who is who is chief executive officer of Quantum Dice – a UK-based start-up that uses quantum optics to generate random numbers. He explains how the company’s technolo ..read more
