The Krafla Magma Testbed "has the potential to be for geoscientists what the Large Hadron Collider has been for particle physicists." So say researchers working on the project to drill into a magma chamber to explore massive geothermal power.

A 5:2 intermittent fasting regime – eating for five days, fasting for two – protected against liver inflammation and didn’t cause weight gain, say researchers, who also identified the proteins that provide this protective effect.

A study has found that having two APOE4 genes may not just be a risk factor in Alzheimer's disease, but a driver of it. Nearly all carriers' brains showed key disease biomarkers by age 65, suggesting it may instead be a type of inheritable Alzheimer's.

Textron is developing a remarkable new Surface Effect amphibious transport for the US Navy and Marines. It can carry 50 tonnes of cargo, skims the waves at 50+ knots (57+ mph, 92+ km/h), and operates in water just four feet (1.2 m) deep.

The discovery of rare painted rock art featuring cattle in one of the driest parts of the Sahara Desert indicates that the region was once covered in grass, swamps and waterholes, making it a resource-rich home to a diverse community of animal species.
