What is the longest earthquake?

A devastating earthquake in Indonesia in 1861 was the crescendo of a 32-year-long clash between the tectonic plates below the island. It is the longest such 'slow slip event' ever recorded, and it left its mark in the bodies of the long-lived corals that inhabit the seas above.

A 32-year-long undersea quake was recorded in coral. Plus, Thailand’s pioneer of mRNA COVID vaccines and what the science says about lifting mask mandates. Coral microatolls, such as this one, cannot grow when exposed to air, so their fossilized bodies record elevation changes that push them up out of the water.Aron Meltzner/Earth Observatory of Singapore A devastating earthquake in Indonesia in 1861 was the crescendo of a 32-year-long clash between the tectonic plates below the island. It is the longest such ‘slow slip event’ ever recorded, and it left its mark in the bodies of the long-lived corals that inhabit the seas above. Researchers analysed growth patterns in corals on Simeulue Island, which were periodically exposed to the air as the land rose up and down. The corals record decades of vertical movement at the fault, from 1738 to the moment they died when thrust up by the 1861 quake. The findings will help seismologists to better understand some of the most dangerous quakes on Earth: the 2004 Indian Ocean earthquake and tsunami that killed more than 220,000 people were preceded by a slow slip.

Two books offer complementary insights into how artificial intelligence (AI) is shaping society. In The Alignment Problem, writer Brian Christian gives an intimate view of the people making AI technology — their aims, expectations, hopes, challenges and desolations. In Atlas of AI, scholar Kate Crawford deals with how, practically, AI gets into and plays out in our lives. “Meticulously researched and superbly written, these books… show that the responsible — ethical, legal and beneficial — development and use of AI is not about technology,” writes reviewer Virginia Dignum. “It is about us.”

Even laboratory-grown meat is made from cows — or from one cow, at least. Researchers must start with conventional meat cells, which someday might serve as the seed for huge bioreactors churning out more environmentally sound, ethical flesh. This means scientists must get their hands on reliable cell lines to study — but in the secretive world of cultured meat, no one wants to share. “There’s basically nowhere to start yet. If anyone wants to get into this field, it takes a significant amount of resources and time to acquire and characterize a cell line in-house,” says cultivated-meat researcher Elliot Swartz.

Which country is Ice and fire?

Iceland Iceland is well known as the land of fire and ice, the small country being home to both glaciers and volcanos.

Iceland is well known as the land of fire and ice, the small country being home to both glaciers and volcanos. All eyes were recently on the Bardarbunga volcano, which was was threatening to erupt and disrupt flight travel in the area. Photographer Lukas Gawenda offers stunning aerial views of the country in his series, Iceland from Above. Lukas Gawenda Lukas Gawenda has created abstract images of Iceland, flying over the small island nation each fall. A selection of images from his series, Iceland from Above, is featured here but a wider variety of Gawenda's work can be seen on his website. Lukas Gawenda Lukas Gawenda has said that his image making is inspired by the desire to preserve nature, and the challenge of presenting natural wonders in a new way. Lukas Gawenda His images offer a unique vantage point, flattening the landscape into painterly swirls of color that are caused by different elements: iron oxide for red, bog soil for yellow and blue from glacial rivers. Lukas Gawenda In additon to Iceland, Lukas Gawenda has photographed landscapes in the United States, Morocco, and numerous locations in Europe, where he is from. Lukas Gawenda
