Richard Bond and George Efstathiou: meet the astrophysicists who are shaping our understanding of the early universe – Physics World

2 days ago | physicsworld.com | Hamish Johnston

This episode of the Physics World Weekly podcast features George Efstathiou and Richard Bond, who share the 2025 Shaw Prize in Astronomy, “for their pioneering research in cosmology, in particular for their studies of fluctuations in the cosmic microwave background (CMB).
Wireless e-tattoos help manage mental workload – Physics World

4 days ago | physicsworld.com | Tami Freeman

Managing one’s mental workload is a tricky balancing act that can affect cognitive performance and decision making abilities. Too little engagement with an ongoing task can lead to boredom and mistakes; too high could cause a person to become overwhelmed. For those performing safety-critical tasks, such as air traffic controllers or truck drivers for example, monitoring how hard their brain is working is even more important – lapses in focus could have serious consequences.
Ask me anything: Tom Woodroof – 'Curiosity, self-education and carefully-chosen guidance can get you surprisingly far' – Physics World

Tom Woodroof did a PhD in applied nuclear physics at the University of Liverpool, UK, before leaving academia to find ways to build a more equitable and sustainable economy.
Leinweber Foundation ploughs $90m into US theoretical physics – Physics World

1 week ago | physicsworld.com | Michael Banks

The Leinweber Foundation has awarded five US institutions $90m to create their own theoretical research institutes. The investment, which the foundation says is the largest ever for theoretical physics research, will be used to fund graduate students and postdocs at each institute as well as several Leinweber Physics Fellows. The Leinweber Foundation was founded in 2015 by the software entrepreneur Larry Leinweber.
China launches Tianwen-2 asteroid sample-return mission – Physics World

1 week ago | physicsworld.com | Michael Banks

China has launched its first mission to retrieve samples from an asteroid. The Tianwen-2 mission launched at 01:31 a.m. local time on 28 May from the Xichang satellite launch center, southwest China, aboard a Long March B rocket. Tianwen-2’s target is a small near-Earth asteroid called 469219 Kamoʻoalewa, which is between 15-39 million km away and is known as a “quasi-satellite” of Earth.
How magnetar flares give birth to gold and platinum – Physics World

1 week ago | physicsworld.com | Keith Cooper

Powerful flares on highly-magnetic neutron stars called magnetars could produce up to 10% of the universe’s gold, silver and platinum, according to a new study. What is more, astronomers may have already observed this cosmic alchemy in action. Gold, silver, platinum and a host of other rare heavy nuclei are known as rapid-process (r-process) elements.
Teaching quantum physics to everyone: pictures offer a new way of understanding – Physics World

1 week ago | physicsworld.com | Hamish Johnston

Part of our International Year of Quantum Science and Technology coverage Quantum science is enjoying a renaissance as nascent quantum computers emerge from the lab and quantum sensors are being used for practical applications. As the technologies we use become more quantum in nature, it follows that everyone should have a basic understanding of quantum physics.
Secondary dose checks ensure safe and accurate delivery of adaptive radiotherapy – Physics World

1 week ago | physicsworld.com | Tami Freeman

ThinkQA Secondary Dose Check software provides quality assurance for every fraction of adaptive radiotherapy without impacting the clinical workflow Adaptive radiotherapy, an advanced cancer treatment in which each fraction is tailored to the patient’s daily anatomy, offers the potential to maximize target conformality and minimize dose to surrounding healthy tissue. Based on daily scans – such as MR images recorded by an MR-Linac, for example – treatment plans are adjusted each day to...
Richard Bond and George Efstathiou share the 2025 Shaw Prize in Astronomy – Physics World

1 week ago | physicsworld.com | Matin Durrani

The 2025 Shaw Prize in Astronomy has been awarded to Richard Bond and George Efstathiou “for their pioneering research in cosmology, in particular for their studies of fluctuations in the cosmic microwave background”. The prize citation continues, “Their predictions have been verified by an armada of ground-, balloon- and space-based instruments, leading to precise determinations of the age, geometry, and mass–energy content of the universe”.
Has bismuth been masquerading as a topological material? – Physics World

1 week ago | physicsworld.com | Anna Demming

Bismuth has puzzled scientists for nearly 20 years. Notably, the question of whether it is topological – that is, whether electrons behave differently on its surface than they do inside it – gets different answers depending on whether you ask a theorist or an experimentalist. Researchers in Japan now say they have found a way to resolve this conflict. A mechanism called surface relaxation, they report, may have masked or “blocked” bismuth’s true topological nature.
