On Beyond Plastic- Mushrooms and Spider Silk

The Great Pacific Garbage Patch comprises three massive, floating marine debris “islands” within a circular ocean current, or gyre - stark reminders of the major environmental pollutant that plastic has become. Fortunately, scientists and engineers are developing novel alternatives for tasks currently filled by petrochemicals. Two alternative packaging materials that especially intrigue me are the mycelium of fungus like mushrooms and spider silk.

Comets and the Christmas Star

The Star of Bethlehem, or the Christmas Star, has an important place in tradition. A mystery surrounds the history of this star, and searches for an explanation have concerned theologians, philosophers, and scientists for nearly 2,000 years. In this post, I focus on whether astronomers have identified a celestial body that could have been a Christmas star.

Expanding Iceland

Erupting volcanoes are forming new real estate all around our planet. Beneath Iceland and Hawaii, hot lava upwelling from deep underground is hardening into rock. Hotspots create chains of volcanoes on these islands as a tectonic plate slowly crosses a mantle plume. In Iceland, there are also volcanic eruptions occurring from the location astride the spreading center known as the Mid-Atlantic Ridge. The result: LOTS of lava.

Seafloor Surprises – What We Are Learning

Opportunities from mining metals like manganese and cobalt to developing new drugs are being found by researchers who are examining our oceans more carefully. Polymetallic nodules, sometimes referred to as “a battery in a rock”, have attracted particular attention. By volume, the oceans provide an astonishing 99 percent of the planet’s living space. We have a lot to learn about these complex and fragile environments.

Ancient Boats and Enormous Blocks

How did the ancient Andeans and Egyptians move the massive stone blocks used to build their monumental architecture? With an abundance of human muscle power but only simple hand tools, they needed to be creative. Floating blocks on boats across lakes and along river channels was a possible transport method—but did they have the water and the engineering technology for this?

Volcano and Earthquake Surprises

Earthquakes and volcanoes can provide us with surprising and unexpected new data. Just within this century, several dramatic events have increased our understanding of these natural hazards, including the catastrophic 2004 Sumatra-Andaman earthquake and tsunami in Indonesia, and the 2011 Tohoku earthquake in Japan. Now, examination of the events leading up to a 2021 volcanic eruption has brought new – and sobering - information.

Protecting Significant Sites in Egypt, Peru and Beyond

Safeguarding ancient Egyptian cultural treasures in the 1960s laid the groundwork for the UNESCO World Heritage Site program. These designations provide protections for places having outstanding cultural and natural heritage. Both Egypt and Peru have fabulous archaeological sites with World Heritage designations, and I’ve had the good fortune to see many. I hope to visit World Heritage Sites in many other countries.

Creatures from the Moche World

Ancient Moche artists created an exceptional level of ceramic art over 1,500 years ago when this culture prospered along the arid north coast of Peru. They produced realistic three-dimensional ceramic forms of people and animals, and they decorated vessels with exquisite fine-line drawings. Several aspects of Moche ceramics recently caught my interest, especially the realistic ceramic animals and the drawings of supernatural creatures.
