The Trump administration is rolling back a landmark conservation rule from the Clinton era that prevents roadbuilding and logging on roughly 58 million acres of federal forest and wildlands.

The announcement rescinding the 2001 Roadless Rule comes as the Forest Service is under orders by President Trump to increase logging and thinning in forests to address the wildfire threat. Environmentalists have already indicated they’ll sue to prevent its reversal, however.

After Clinton enacted the rule at the end of his term in 2001, it effectively created de facto wilderness protections for scores of forests in the West and Alaska.

An indigenous sculptor from a small village in Yucatán has recreated the ancient Maya process of extracting blue paint from a native plant via a chemical reaction.

Luis May Ku, 48, saw years of research finally pay off in January, when scientists in Italy and Mexico confirmed that his formula was genuine, making it officially the first time that the world has seen the traditional Maya Blue pigment made in almost two centuries.

Perhaps even more impressive is that this happened within the confines of a self-made laboratory.

The ancestral pigment is known for its unique resistance to weathering, allowing it to appear relatively untouched after more than 1,000 years. It was made and used by Mesoamerican cultures during a period extending from about the eighth century until just after the mid-19th century.

Fantastic pre-Columbian murals and pottery fragments discovered around important archaeological sites show evidence the color was considered exclusive to the gods or to those chosen for ritual sacrifice.
