A University of Southampton study has revealed an intriguing new clue in the mystery of what triggers periods of very intense, brightly colored activity during displays of both the southern and northern lights.

Known as a “magnetospheric substorm,” this awe-inspiring phenomenon, which blankets the night sky in green and purple, is almost always preceded by what space scientists call “auroral beads”—a necklace-like wave of multiple luminous points of light which eventually evolve into the storm.

Southampton scientists have now shown there is a link between these auroral beads and the intensity of low frequency radio waves above the aurora in Earth’s magnetosphere—a vast area around our planet that is dominated...

A study conducted at Harvard University identified a group of metabolites that travel from the intestine to the liver and then to the heart, where they are pumped throughout the body. These metabolites play an important role in controlling metabolic pathways in the liver and insulin sensitivity. This discovery may contribute to future treatments for obesity and type 2 diabetes. The results were published in the journal Cell Metabolism.

Soft robots are prized for their agility and gentle touch, which makes them ideal for traversing delicate or enclosed spaces to perform various tasks, from cultivating baby corals in laboratories to inspecting industrial pipes in chemical plants. However, achieving embodied intelligence in such systems, where sensing, movement and power supply work together in an untethered configuration, remains a challenge.

Flexible materials can deform and adapt, but their power sources are unable to do so. Conventional batteries often stiffen the robot’s body, drain quickly, or degrade under strain, all of which leave soft robots tethered or with a short lifespan.

Assistant Professor Wu Changsheng and his team from the Department of Materials Science and Engineering and the Department of Ele...

Imagine biting into a crisp, garden-fresh salad and savoring juicy strawberries for dessert. But instead of your backyard, you’re gazing out at a stark lunar landscape, Earth hanging like a precious blue marble in the inky sky.

Sound like far-fetched sci-fi? Think again.

This cosmic cuisine scenario is fast becoming our reality, thanks to research led by University of Melbourne scientists belonging to the Australian Research Council Centre of Excellence in Plants for Space (P4S, 2024-2030), in partnership with NASA and other space scientists.

A global dream team of over 40 scientists in 11 countries and seven space agencies have united to produce a roadmap for plant science breakthroughs crucial for long-term human life on the moon and Mars.

And...
