In the first ever measurement of another planet’s core, seismography conducted over several Martian years have revealed the liquid metal core is softer than expected—more like a Mars-mellow than a Mars Bar. While the recently arrived Perseverance rover has been hoovering up much of the Mars-related attention, a trio of recently published papers that measured […]

Stunning Train Station Being Built in Mexico Uses Mayan Design to Bring Sea Air in and Keep Rain Out
The ancient Maya civilization was enshrining its legacy in stone more than a thousand years ago, and the ingenious designs from that time are being utilized in fresh ways today. On a 950-mile (1,525 -kilometer) Mexican railway line, a new station to service the Yucatán town of Tulum is being built using techniques right out […]
(GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre) The plates of the Earth’s crust perform complicated movements that can be attributed to quite simple mechanisms. That is the short version of the explanation of a rift that began to tear the world apart over a length of several thousand kilometers 105 million years ago. The scientific explanation appears in Nature Geoscience.
Most buildings were designed for an earlier climate – here’s what will happen as global warming accelerates – The Conversation UK
Climate change will affect every aspect of our lives – including the buildings we live and work in. Most people in the US, for example, spend about 90% of their time indoors. Climate change is fundamentally altering the environmental conditions…
The national primary-school English teachers’ association has launched a climate propaganda blitz on the 5- to 14-years-olds placed in their care. The teachers’ just-released manual spruiks intermittent wind and solar and demands an end to coal-fired electricity and fossil fuels….
Staggering images taken from planes using forest-penetrating radar are mapping the geology of Washington state. Intriguing, artsy, beautiful, and outright bizarre, “The Bare Earth” presentation on the Washington state Department of Natural Resources (DNR) website uses shading and added color to present underlying geological features like lava flows, glacial moraines, drumlins, tsunami inundation, mudslides, eruptions, […]

Earth’s most recent supervolcano is the Taupo supervolcano, from 25,000 years ago. It experienced unrest in 2019. Scientists want to know more.

The Port of San Francisco (which manages 7.5 miles of the city’s waterfront, including the three miles buttressed by the sea wall) had assumed the wall needed upgrading, but it did not know just how direly until 2016, when officials…
(Université de Genève) A team led by UNIGE has reviewed the literature on the internal and external mechanisms that lead to a volcanic eruption. Analyzing the thermo-mechanics of deep volcanic processes and magma propagation to the surface, together with magma chemistry, the geologists determined that most of the magma rising from depth actually does not cause a volcanic eruption. They also show that older volcanoes tend to produce less frequent, but larger and more dangerous eruptions.
