Ultrasound system solves the ‘unsticking problem’ in biomedical research

05 Mar 2026 Hamish Johnston

“Surround sound for biological cells,” is how Luke Cox describes the ultrasound technology that Impulsonics has developed to solve the “unsticking problem” in biomedical science. Cox is co-founder and chief executive of UK-based Impulsonics, which spun out of the University of Bristol in 2023.

He is also my guest in this episode of the Physics World Weekly podcast. He explains why living cells grown in a petri dish tend to stick together, and why this can be a barrier to scientific research and the development of new medical treatments.

Asteroid deflection: why we need to get it right the first time

 

Asteroid deflection: why we need to get it right the first time

12 Feb 2026 Hamish Johnston

Science fiction became science fact in 2022 when NASA’s DART mission took the first steps towards creating a planetary defence system that could someday protect Earth from a catastrophic asteroid collision. However, much more work on asteroid deflection is needed from the latest generation of researchers – including Rahil Makadia, who has just completed a PhD in aerospace engineering at the University of Illinois at Urbana-Champaign.

In this episode of the Physics World Weekly podcast, Makadia talks about his work on how we could deflect asteroids away from Earth. We also chat about the potential threats posed by near-Earth asteroids – from shattered windows to global destruction.

Long-distance quantum sensor network advances the search for dark matter

A new way of searching for dark-matter candidate particles called axions has produced the tightest constraint yet on how they can interact with normal matter. Using a two-city network of quantum sensors based on nuclear spins, physicists in China narrowed the possible values of a parameter known as axion-nucleon coupling below a limit previously set by astrophysical observations. As well as insights into the nature of dark matter, the technique could aid investigations into other beyond-the-Standard-Model phenomena, such as axion stars, axion strings, and Q-balls.

The ancient reversal of Earth’s magnetic field took an extraordinarily long time

The Earth’s magnetic poles have reversed 540 times over the past 170 million years. Usually, these reversals are relatively speedy in geological terms, taking around 10,000 years to complete. Now, however, scientists in the US, France, and Japan have found evidence of much slower reversals deep in Earth’s geophysical past. Their findings could have important implications for our understanding of Earth’s climate and evolutionary history.

Scientists think the Earth’s magnetic field arises from a dynamo effect created by molten metal circulating inside the planet’s outer core. Its consequences include a bubble-like magnetosphere that shields us from the solar wind and cosmic radiation that would otherwise erode our atmosphere.

A researcher in Japan has proposed a new way to extract energy from ocean waves. The system couples a gyroscope to an electrical generator and could be fine-tuned to extract energy from a wide range of wave conditions. A prototype of the design is currently being built for testing in a wave tank. If successful, the system could be used to generate electricity on board ships.

Ocean waves contain vast amounts of energy, and humans have sought to harness it for centuries. Despite the development of myriad technologies and numerous trials, the widespread commercial conversion of wave energy remains an elusive goal. One important problem is that most generation schemes only work within a narrow range of wave conditions – and the ocean can be a very messy place.

The heads of university physics departments in the UK have published an open letter expressing their “deep concern” about funding changes announced late last year by UK Research and Innovation (UKRI), the umbrella organization for the UK’s research councils.

Addressed to science minister Patrick Vallance, the letter says the cuts are causing “reputational risk” and calls for “strategic clarity and stability” to ensure that UK physics can thrive.

It has so far been signed by 58 people who represent 45 different universities, including Birmingham, Bristol, Cambridge, Durham, Imperial College, Liverpool, Manchester, and Oxford.

Machine learning could help us use cosmic muons to peer inside large objects, such as nuclear reactors. Developed by researchers in China, the technique can identify target materials such as uranium even when they are coated with other materials.
The muon is a subatomic particle, essentially a heavier version of the electron. Huge numbers of cosmic muons are created in Earth’s atmosphere when cosmic rays collide with gas molecules. Thousands of cosmic muons per second rain down on every square metre of Earth’s surface, and these particles can penetrate tens to hundreds of metres through solid materials.

Metamaterial antennas enhance MR images of the eye and brain

 

Metamaterial antennas enhance MR images of the eye and brain

In vivo MR imaging
MRI is one of the most important imaging tools employed in medical diagnostics. But for deep-lying tissues or complex anatomic features, MRI can struggle to create clear images in a reasonable scan time. A research team led by Thoralf Niendorf at the Max Delbrück Center in Germany is using metamaterials to develop a compact radio-frequency (RF) antenna that improves image quality and enables faster MRI scanning.

Imaging the subtle structures of the eye and orbit (the surrounding eye socket) is a particular challenge for MRI, due to the high spatial resolution and small fields-of-view required, which standard MRI systems struggle to achieve. These limitations are generally due to the antennas (or RF coils) used to transmit and receive RF signals. Increasing the sensitivity of these antennas will increase signal strength and improve the resolution of the resulting MR images.

India has unveiled plans to build two new optical-infrared telescopes and a dedicated solar telescope in the Himalayan desert region of Ladakh. The three new facilities, expected to cost INR 35bn (about £284m), were announced by the Indian finance minister Nirmala Sitharaman on 1 February.

First up is a 3.7 m optical-infrared telescope, which is expected to come online by 2030. It will be built near the existing 2 m Himalayan Chandra Telescope (HCT) at Hanle, at an altitude of about 4500 m above sea level. Astronomers use the HCT for a wide range of investigations, including stellar evolution, galaxy spectroscopy, exoplanet atmospheres, and time-domain studies of supernovae, variable stars, and active galactic nuclei.

More than 250 quantum scientists have signed a “manifesto” opposing the use of quantum research for military purposes. The statement – quantum scientists for disarmament – expresses a “deep concern” about the current geopolitical situation and “categorically rejects” the militarization of quantum research or its use in population control and surveillance. The signatories now call for an open debate about the ethical implications of quantum research.

While quantum science has the potential to improve many different areas – from sensors and medicine to computing – some are concerned about its applications for military purposes. They include quantum key distribution and cryptographic networks for communication, as well as quantum clocks and sensing for military navigation and positioning.
