Noble gases dissolved in an ice core from Antarctica have revealed global mean ocean temperatures for 22,000–8,000 years ago with unprecedented accuracy, providing a crucial benchmark for refining climate models.
Methods for making interfaces between atomically thin sheets of materials might open the way to a range of nanotechnologies. A practically simple method has been reported, based on the cyclical switching of gaseous reagents.
Monitoring microbes that live deep inside the gut is a challenge. Engineering bacteria to express structures that can be tracked by ultrasound offers a way to locate such cells in vivo, and might have clinical implications.
