For the first time in the world, a joint research team from NIMS, Nagoya University and The University of Tokyo has successfully observed the transverse Thomson effect—a phenomenon in which metals or semiconductors release or absorb heat when a heat current, charge current and magnetic field are applied orthogonally to each other. This achievement may contribute to advances in physics and materials science related to the conversion between heat, electricity and magnetism, as well as to the development of new thermal management technologies. The research was published in Nature ...

Quantum networks are often described as the future of the internet — but instead of transmitting classical information in bits, they send quantum information carried by photons. These networks could enable ultra-secure communication, link together distant quantum computers into a single, vastly more powerful machine, and create precision sensing systems that can measure time or environmental conditions with unprecedented accuracy. To make such a network possible, so-called quantum network nodes — that can store ...

Understanding how fat molecules are distributed and function in living organisms is key to uncovering mechanisms of aging, disease, and metabolism. Caenorhabditis elegans, a transparent roundworm, is a widely used model for studying fat storage due to its genetic similarity to humans and well-defined anatomy. However, visualizing lipids at high resolution in such a small organism has posed a major technical challenge.   A research team at Okayama University, Japan, led by Professor Masazumi Fujiwara and his PhD student Ms. Sara Mandic, in collaboration with Professor Ron M. A. Heeren of ...

Asteroid Bennu — the target of NASA's OSIRIS-REx sample return mission, led by the University of Arizona — is a mixture of materials from throughout, and even beyond, our solar system. Over the past few billion years, its unique and varied contents have been transformed by interactions with water and the harsh space environment. These details come from a trio of newly published papers based on analysis of Bennu samples delivered to Earth by OSIRIS-REx in 2023. The OSIRIS-REx sample analysis campaign is coordinated by the U of A's Lunar and Planetary Laboratory (LPL) and involves scientists from around the world. ...

Batteries in electric vehicles wear out too quickly and this is slowing down the electrification of the transport sector. Researchers at Uppsala University have now developed an AI model that can provide a much more accurate picture of battery ageing. The model could lead to longer life and enhanced safety for electric vehicle batteries. It is not uncommon for batteries in electric cars to be the first component of the vehicle to age. This is a major waste of resources today and is holding back the transformation ...

New research unveils the true death toll of the deadly August 2023 wildfires which took place in Lāhainā, Maui, Hawaiʻi — and which temporarily made wildfire a leading cause of death in Maui. By comparing death rates over time, the scientists found that two-thirds more people died that August than would have been expected. To stop this happening again, the authors say, major policy changes are needed, ranging from removing flammable invasive vegetation to improving disaster preparedness.   “Wildfires can cause a measurable, ...

Fukuoka, Japan— Researchers at Kyushu University have demonstrated that yogurt intake increases the diversity of gut microbiota and alters its composition. Furthermore, bathing in chloride hot springs after yogurt intake was found to improve defecation status more than yogurt alone. These findings suggest that combining two lifestyle interventions—yogurt intake and hot spring bathing—may contribute to better health, highlighting their potential application for preventive medicine. The study was published in the journal Frontiers in Nutrition. Maintaining a healthy gut environment ...

Translocations are chromosomal “cut and paste” errors that drive many lymphomas, a type of blood cancer and the sixth most common form of cancer overall. This includes mantle cell lymphoma, a rare but aggressive subtype diagnosed in about one in every 100,000 people each year. Translocations are known to spark cancer by altering the activity of the genes near the breakpoints where chromosomes snap and rejoin. For example, a translocation can accidentally cut a gene in half, silencing its activity, or create new hybrid proteins ...

-With images and video-   A new Durham University study has found that a giant impact may not be responsible for the formation of Jupiter's remarkable ‘dilute’ core, challenging a theory about the planet's history.   Jupiter, the largest planet in our solar system, has a mystery at its heart. Unlike what scientists once expected, its core doesn’t have a sharp boundary but instead gradually blends into the surrounding layers of mostly hydrogen (a structure known as a dilute ...

A new study has revealed that racialized and Indigenous communities across Europe, North America, and Central America face significantly higher rates of cardiovascular disease (CVD), and that gaps in health-care data are making the problem worse. CVD is the leading cause of death worldwide but does not affect people equally. In many countries, Black, South Asian and Indigenous peoples have higher rates of heart disease, diabetes, or high blood pressure compared to white populations. Without an understanding of who is most at risk and why, health systems are unprepared ...

Did you know the same protein that gives blood its red color and carries oxygen throughout the body is also present inside brain cells? Hemoglobin, long celebrated for ferrying oxygen in red blood cells, has now been revealed to play an overlooked — and potentially game-changing — antioxidant role in the brain. In neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Parkinson’s, Alzheimer’s, and aging, brain cells endure relentless damage from the aberrant (or excessive) reactive oxygen species (ROS). For decades, scientists have tried to neutralize ROS with antioxidant ...

The mystery at Jupiter's heart has taken a fresh twist – as new research suggests a giant impact may not have been responsible for the formation of its core. It had been thought that a colossal collision with an early planet containing half of Jupiter's core material could have mixed up the central region of the gas giant, enough to explain its interior today. But a new study published in Monthly Notices of the Royal Astronomical Society suggests its make-up is actually down to how the growing planet absorbed heavy and light materials as it formed and evolved. Unlike what scientists ...

Researchers have developed a new, data-driven way of fitting prosthetic legs which could lead to better fitting prosthetics, in less time and at a lower cost. The technology has been developed by Radii Devices and the University of Southampton, and the results of an NHS trial have been published today [22 August 2025] in JMIR Rehabilitation and Assistive Technology. The study shows that below-the-knee prosthetic limbs designed using the new approach were as comfortable on average as those created by highly skilled prosthetists, but with more consistent results. Crucially, the new method generates a basic ...

Under or over? The twists and turns of genetic research DNA is a molecule that can get twisted and tangled - a process that must be closely regulated  A research team has developed an automated technique to visualise and measure DNA tangles Technique is so precise it can tell if one DNA segment passes under or over another At school, it’s often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules.   DNA is a molecule found in just about every living cell. Because the molecule is long, it ends up twisting on itself and getting tangled. Enzymes in the body try to regulate this process but when that ...
