Changing plant chloroplasts to improve crop performance

Chloroplasts are tiny protein-filled units within plant cells. As well as being responsible for photosynthesis, they are critical to a plant's ability to respond to its environment (for example, to the intensity of light or the threat of disease). They do this by importing the proteins they need...

Mechanobiology: the stress of life

We often think of our bodies in terms of cells and genes, but we shouldn’t forget that they’re also complex mechanical structures. From an Achilles tendon – that can carry half the weight of a Mini – to our constantly pulsing blood vessels, they’re feats of meticulous engineering. Scientists at...

Using your science to understand volcanic eruptions

Volcanoes are present across the Earth, from the barren wastes of Antarctica to densely populated regions in Europe, Asia and the Americas, and are both spectacular and deadly. But what makes a volcano erupt, and how...

Using your science to reveal how much rain fell on the dinosaurs

During the Cretaceous period (145 to 66 million years ago), the world was very different! It was hotter, with more rainfall, and dinosaurs would have roamed the lush wetlands and forests that existed in the UK....

Using your science to explore the climate history of Mars

Mars today is colder than Antarctica and drier than the Sahara — but scratch just beneath its dusty red coating and tales of a different planet emerge. The young Mars of three billion years ago was an Earth-like place of rain, rivers, and perhaps even oceans. Though long-gone, the rocks remember...

Our mysterious ocean floor

Oceans cover more than 70% of the Earth's surface, yet only 15% of the ocean floor has been mapped in detail. Much remains unknown, including the location of potentially hundreds of thousands of seamounts, which can be hazardous to navigation. Scientists at the University of Oxford are working...
