If puberty is like climbing a physiological cliff, then menopause may be like falling off one. A new study, published in Nature Medicine, argues that the end of menstruation is not a gradual part of aging, as previously assumed, but an abrupt physiological transition. Using more than 300 million lab tests from over one million women, the new study identifies a number of sudden 'jumps' that occur throughout the body when menopause begins. Some of the most obvious changes are to do with sex hormones, which the ovaries help produce, but there are also sudden shifts in bone health, liver function, kidney function, blood chemistry, and blood fats. "Menopause reshapes female physiology, yet current understanding islimited by small longitudinal cohorts that characterize it as a gradualtransition," explain the authors, led by molecular cell biologist Glen Pridham from the Weizmann Institute of Science in Israel. That may be a misconception.

Pridham and colleagues have instead used a computational framework to analyze the transition to menopause in two large cohorts of women, one in the United States and another in Israel.

Ancient mud reveals a surprising secret about Greenland’s ice - Earth.com

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.
