Double helix of masonry: Researchers discover the secret of Italian renaissance domes

Researchers found that the masonry of Italian renaissance domes, such as the duomo in Florence, use a double-helix structure that is self-supporting during and after construction. Their study is the first to quantitatively prove the forces at work in such masonry domes, which may lead to advances in modern drone construction techniques.

The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5
