00:46 The role of skull bone marrow in ageingDuring ageing, bone marrow in the skull becomes an increasingly important site of blood-cell production. This is in stark contrast to most bones where the ability of marrow to make blood and immune cells declines. Studies in mice and humans showed that ageing results in skull bone-marrow expanding, and in mice this marrow was more resistant to inflammation and other hallmarks of ageing. The team behind the work hope by understanding this process better it

00:46 Mitochondria divide their labour to help cells thriveResearchers have uncovered that mitochondria divide into two distinct forms when cells are starved, a finding that could help explain how some cancers thrive in hostile conditions. Mitochondria are cellular powerhouses, creating energy and vital metabolic molecules, but how they are able to do this when resources are limited has been a mystery. It turns out that in nutrient-poor situations, mitochondria split into two separate types, one

The cities were thought to be there, but their extent was unknown, so the team used drone-mounted LiDAR equipment to reveal what was hidden beneath the ground. The survey surprised researchers by showing one of the cities was six times bigger than expected. The two cities, called Tashbulak and Tugunbulak, were nestled in the heart of Central Asia’s medieval Silk

These objects are thought to be a source of galactic cosmic rays, the origins of which are currently a mystery.Understanding how this microquasar works could also help researchers learn more about full-sized quasars — monstrous

Graphene has long been sought after as a chemical sensor, but tiny variations between devices have meant that it couldn’t be used very reliably. The team behind the ‘tongue’ got around this problem by training an AI to tell the difference between similar liquids regardless of variations between graphene devices. They hope that their work shows that it’s possible to use

Jets are formed when matter is ionized and flung out of a black hole, creating enormous and powerful structures in space. Thought to be unstable, physicists had theorized there was a limit to how large these jets could be, but the new discovery far exceeds this, suggesting

According to a group of researchers, including those from Indigenous groups, this baseless statistic could be undermining the conservation efforts of the Indigenous People it's meant to support and prevent further work to really understand how best to conserve biodiversity.Two of the authors joined

Such a timekeeper would differ from the best current clocks as their ‘tick’ corresponds to the energy transitions of protons and neutrons, rather than electrons. Nuclear clocks have the potential to be more
