Coastlines of the Ice Age

Coastlines of the Ice Age - Sundaland

This map shows how the terrain may have appeared during the Last Glacial Maximum, around 21,000 years ago, when sea levels were approximately 125 meters (410 feet) below present. This map does not include any lakes of this time period. The colouring of the map is based on height, and is not meant to represent the climate or vegetation in any way.

This map has some noticable lines running in different directions across the landscape that appear as ridges or trenches. These in most cases are more than likely to be an issue caused by merging different quality datasets. The sonar scanning that was used to map the seabed will pick up higher accuracy readings of depth along the path that the ships travel, and when merged with lower quality height data of the surrounding areas, will appear to stand out.

How Long Does Plastic Take to Decompose?

Plastic: the unwelcome house guest at nearly every corner of our lives — from shopping bags to footwear, coffee cups to car parts. And yet, discarded, plastic doesn't just evaporate into thin air. No, it lingers. For decades. Even centuries. According to statistics presented by Visual Capitalist , plastic daily consumer goods can break down between 20 and 600 years, depending on the composition used, how they were created, and natural elements like water and sunlight they are exposed to. Let's go deeper into why plastic takes so long to break down — and what horrid messes it leaves behind in the process. Why Plastic Isn't "Natural" — and Why That's a Problem Plastic does not naturally exist. It's a product made from petroleum and natural gas. Its long, tough carbon bonds differ from anything naturally found in ecosystems, making it extremely resistant to microbial breakdown. When we toss a plastic bottle or bag away, it's not a matter of if it will s...

Fallingwater: Where Architecture Meets the Wild

Located in southwestern Pennsylvania's woods, Fallingwater is not a house, but a powerful conversation between nature and architecture. Completed in 1935 by Frank Lloyd Wright for the Kaufmanns, it's one of the only buildings that truly does seem alive—as if it grew directly out of the rock. What is so revolutionary about Fallingwater isn't its appearance—it's Wright's philosophy of organic architecture: the idea that houses are there to harmonize with nature, not dominate it. The house was actually constructed into the land, resting directly above a waterfall on Bear Run. Instead of looking out over the waterfall, Wright built the waterfall into the house, and the sound of running water is therefore a constant companion. Crafted From the Land, For the Land The materials used to build Fallingwater tell their own story. The stone was quarried on-site. Local craftsmen helped shape every contour. The horizontal lines of the cantilevered terraces echo the layered rock...

Barbie’s Feet Are Getting Flatter—And It Says a Lot About Us

Barbie’s arched feet have long been a part of her image—tiny, pointed, and forever perched for stilettos. But that’s starting to change. A new study reveals that Barbie’s feet are flattening, and that shift isn’t just about doll design—it reflects a broader change in how we think about women’s fashion and comfort. A team of podiatrists at Monash University analyzed 2,750 Barbie dolls produced between 1959 and 2024. They found that while every single doll in the 1960s had permanently arched feet made to fit high heels, only about 40% of Barbies in the 2020s still have that same foot shape. This shift isn’t random. It follows Barbie’s growing list of careers—astronaut, firefighter, doctor—where practical shoes make a lot more sense than stilettos. This change was even acknowledged in the 2023 Barbie movie. In one early scene, Margot Robbie’s Barbie steps out of her heels and her feet stay arched, just like the classic dolls. But later in the film, her feet flatten out, a visual cue ...
