About 20,000 years ago, an enormous, floating ice shelf more than a mile (1.6 kilometers) thick helped lock in three of the largest ice sheets in northern Canada and Greenland. When that ice shelf disappeared, it helped unlock part of these ice sheets, which contributed to hundreds of feet of sea level rise, establishing modern coastlines as we know them.

Whenever I drive amid the mazelike bustle of Tokyo's Shuto Expressway, where approximately 1 million vehicles transit daily, I see billboard advertisements for all manner of businesses: dentists, hotels, car and tire companies, and affordable funerals. Lots and lots of funerals.

Salt marsh sediment and vegetation can remain largely intact even during extreme storm surges. This was demonstrated in a large-scale experiment in which researchers transported sections of salt marsh to an experimental facility capable of producing the world's largest artificial waves. The results show how salt marshes can contribute to natural coastal protection, both in the Netherlands and beyond. The results were published in the journals Nature and Communications Sustainability.

Researchers at Eötvös Loránd University (ELTE) have reconstructed approximately 16,000 years of summer temperature changes from sediments collected at Lake Prokoško in Bosnia and Herzegovina. The findings show how the Western Balkans responded to rapid climate changes at the end of the last glacial period, how warmer and cooler phases unfolded during the Holocene, and how the impact of human land use became increasingly pronounced.

Imagine you have a bag you really like. It felt like "the one" when you bought it. Over time, it starts to look worn. There are some scuffs on it. Nothing is actually wrong with the bag, and it still works exactly as it should. Yet, once you notice those imperfections, you start thinking about buying a new one to replace it.

What causes adversaries to escalate conflicts into costly, prolonged wars even when neither side wants to fight? And in the fog of war, what might help them break that cycle and find a path to peace?

Look closely at a face in a painting and you might think you know what emotion the person is experiencing. A smile suggests happiness. A furrowed brow might signal anger. Widened eyes could mean fear or surprise. But what happens when you ask lots of people the same question? Do they see the same emotion, or something more complicated?

The media habits of teens and young adults reflect transformative changes in modern storytelling and technology, and the entertainment industry and other content creators should pay attention, according to the latest "Teens and Screens" report from the Center for Scholars & Storytellers (CSS) at UCLA.

A team of researchers at NASA's Goddard Space Flight Center (GSFC) has developed a new instrument designed to eliminate blind spots between lines of lidar data on Earth's surface. Built with support from NASA's Earth Science Technology Office (ESTO), the Concurrent Artificially-intelligent Spectrometry Lidar System (CASALS) could help researchers map the features of Earth's surface in detail. Rather than mechanically steering a laser with moving mirrors, CASALS steers light using wavelength itself, generating a continuous, 3D swath of the ground below.

Compulsive use of social media may be associated with a strong desire for reassurance among people who are afraid to rely on others and engage in face-to-face interactions, according to a study published Oct. 21, 2026, in the journal PLOS One by Chris Bjornsen and Allen Harbaugh of Longwood University in the U.S.
