Archaeologists verify Florida’s Mound Key as location of elusive Spanish fort

Florida and Georgia archaeologists have discovered the location of Fort San Antón de Carlos, home of one of the first Jesuit missions in North America. The Spanish fort was built in 1566 in the capital of the Calusa, the most powerful Native American tribe in the region, on present-day Mound Key in the center of Estero Bay on Florida’s Gulf Coast.

Archaeologists and historians have long suspected that the fort, named for the Catholic patron saint of lost things, was located on Mound Key. Researchers have been searching for concrete evidence in the area since 2013.

“Before our work, the only information we had was from Spanish documents, which suggested that the Calusa capital was on Mound Key and that Fort San Antón de Carlos was there, too,” said William Marquardt, curator emeritus of South Florida archaeology and ethnography at the Florida Museum of Natural History. “Archaeologists and historians had visited the site and collected pottery from the surface, but until we found physical evidence of the Calusa king’s house and the fort, we could not be absolutely certain.”

SpaceX’s Starlink network surpasses 400-satellite mark after successful launch

After years of studies, test-firings and a survey of U.S. industry in preparation for launch of a Mars Sample Return mission in 2026, NASA has settled on a solid-fueled design for a miniature rocket with a first-of-its-kind purpose: Launching a payload from Mars for a trip back to Earth.

The small launcher is called a Mars Ascent Vehicle, or MAV. The MAV will play a key role in the Mars Sample Return mission being developed by NASA and the European Space Agency.

The first element of the Mars Sample Return mission is NASA’s Perseverance rover scheduled to depart Earth in mid-July. Perseverance will collect core samples from Martian rocks and store them in tubes for retrieval by a future rover that could launch as soon as 2026.

Tectonic plates started shifting earlier than previously thought

An enduring question in geology is when Earth’s tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some researchers theorize it happened around four billion years ago, while others think it was closer to one billion.

A research team led by Harvard researchers looked for clues in (older than 3 billion years) from Australia and South Africa, and found that these plates were moving at least 3.2 billion years ago on the early Earth. In a portion of the Pilbra Craton in Western Australia, one of the oldest pieces of the Earth’s crust, scientists found a latitudinal drift of about 2.5 centimeters a year, and dated the motion to 3.2 billion years ago.

The researchers believe this shift is the earliest proof that modern-like plate motion happened between two to four billion years ago. It adds to growing research that tectonic movement occurred on the early Earth. The findings are published in Science Advances.

Nearly 25,000 email addresses and passwords allegedly from NIH, WHO, Gates Foundation and others are dumped online

Unknown activists have posted nearly 25,000 email addresses and passwords allegedly belonging to the National Institutes of Health, the World Health Organization, the Gates Foundation and other groups working to combat the coronavirus pandemic, according to the SITE Intelligence Group, which monitors online extremism and terrorist groups.


While SITE was unable to verify whether the email addresses and passwords were authentic, the group said the information was released Sunday and Monday and almost immediately used to foment attempts at hacking and harassment by far-right extremists. An Australian cybersecurity expert, Robert Potter, said he was able to verify that the WHO email addresses and passwords were real.

Second 12-tonne haul of pangolin scales seized in less than a week

SINGAPORE — Less than a week after a record 12.9 tonnes of pangolin scales were seized from a container by the authorities here, another 12.7 tonnes have been uncovered in a joint operation by the National Parks Board (NParks), Singapore Customs and the Immigration and Checkpoints Authority (ICA).

The 40ft (12m) container that was on its way by ship from Nigeria to Vietnam was declared to contain “cassia seeds” but was found on Monday (April 8) to be holding the animal parts, estimated to be worth about $51.6 million, in 474 bags at the Pasir Panjang Scanning Station.

The haul came from two species, the white-bellied tree pangolin (Phataginus tricuspis) and the giant ground pangolin (Smutsia gigantea) and are likely to have come from 21,000 pangolins.

What negative US oil prices mean for the industry

Benchmark US crude oil prices traded with negative prices for the first time in history on Monday, sending shockwaves through the global energy sector.

But what are negative prices and what do they mean for the wider industry?

US oil prices traded below zero for the first time ever, meaning producers or traders were essentially paying other market participants to take the oil off their hands.
