WASHINGTON — Puerto Rico has felt hundreds of aftershocks after the Jan. 7 magnitude 6.4 earthquake. And throughout history, earthquakes are not an unheard-of occurrence on the island. This is because of plate tectonics.

Puerto Rico and the adjacent islands surrounding it are sitting on the convergence between two tectonic plates. The islands are on the edge of the Caribbean Plate, which extends to the south in the Caribbean Sea, while the North American Plate is just north of the island.

A bitter blast of Arctic air that brought dangerous wind chills across the Midwest last weekend created erupting “ice volcanoes” on a Lake Michigan beachfront.

The National Weather Service in Grand Rapids said the sight was captured Sunday at Oval Beach in Saugatuck, Mich.

Here’s the first evidence to challenge the “fastest sperm” narrative.

A US firm claims the service it offers saves more than a tonne of carbon, after a pilot study.

Researchers at Haifa’s Technion–Israel Institute of Technology say they have developed a standalone system capable of producing water from air, including in desert regions.

Described as the “first technology of its kind in the world,” the energy-efficient system aims to assist small and isolated communities far from freshwater and saltwater sources.

The newly released volume, After Shock, features 50 of the world’s most renowned futurists reflecting on the 50-year legacy of Alvin Toffler’s Future Shock, and looking ahead to the next 50 years. In this episode recorded just a few days after the book’s release, two of the contributing essayists, Jerome Glenn and Andrew Curry, discuss with me their views on the legacy of Toffler and Future Shock. Below are links to the audio podcast as well as to the unedited YouTube video of the original webinar.

The day I read Future Shock, just a couple of years after it came out, was the day that started me on the course to becoming a futurist. Here’s what I wrote on this blog when Toffler died in July of 2016.

The U.S. Department of Education announced Wednesday that it is launching an investigation into Harvard and Yale after they failed to disclose about $375 million in gifts and contracts from China and Saudi Arabia in the past four years.

Harvard and Yale are the latest in the Education Department’s continuing efforts to crack down on foreign influence, particularly from China. According to the Wall Street Journal, U.S. universities have failed to report they brought in $6.5 billion from foreign nations since 1990.

A major aspect of the alleged foreign influence on universities is through gifts and grants, which can come with strings attached and might compromise their academic independence.
