In polymer science, the classic division is between thermoplastics, which soften and flow when heated, and thermosets, which are permanently cross-linked and keep their shape no matter how hot they get—at least until they burn. In the last decade, researchers have discovered a fascinating new class of materials called vitrimers, which sit between these two […]
Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that causes some intriguing effects. Its electron structure contributes to unconventional entropic properties at low temperatures […]
Attention deficit and hyperactivity disorder, known as ADHD, is the most common neurodevelopmental disorder in children worldwide, with an estimated prevalence of around 5%. Research shows that the condition often continues into adulthood in up to 90% of diagnosed children . Although ADHD has been recognised for decades, it has recently gained much greater visibility […]

A new study has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover. The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation—a name chosen from locations in Grand Canyon National Park because of the […]
Light can do remarkable things, but it has limitations. Ordinary photons are bound by diffraction, which sets a limit on how tightly they can be confined in space. This is why focusing light to spots smaller than about half its wavelength is so difficult. But in certain materials, photons couple to vibrations of atoms or […]

When you look at a crystal—say, a piece of salt or a sheet of graphene—its atoms are not randomly scattered. They form an orderly grid, like tiles on a floor. Because the atoms are arranged in this repeating way, electrons moving through the crystal don’t behave as if they’re in free space. Instead, their motion […]
Author: Samuel Lellouch, Assistant Professor in Digital Twinning, School of Physics and Astronomy, University of Birmingham A US military space-plane, the X-37B orbital test vehicle, is due to embark on its eighth flight into space on August 21 2025. Much of what the X-37B does in space is secret. But it serves partly as a […]
A team of scientists has discovered a new type of crystal that can “breathe”—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices. The newly developed material is a special kind of metal oxide made […]
Positron Emission Tomography, or PET, is one of medicine’s most powerful tools for looking inside the human body, revealing not only anatomy but also how tissues are functioning. In a PET scan, a patient receives a tiny dose of a radioactive tracer that emits positrons, the antimatter counterparts of electrons. When a positron encounters an […]
