‘Know the science that goes into it’: Saskatoon Beer Lab puts beer under the microscope - CTV News

A new microscope developed at Stanford University allows scientists to watch the tiny structures inside living cells move and interact in real time, providing an exceptionally detailed view without the fluorescent labels typically used to make these structures visible. Researchers at Stanford have created a powerful new imaging system that reveals the inner workings of living cells with remarkable clarity. By combining two advanced microscopy techniques, the instrument achieves a resolution of approximately 120 nanometers, an unprecedented level of detail for an approach that does not require fluorescent labels.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
