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.

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.

The lists, whose origins are unclear, appear to have first been posted to 4chan, a message board notorious for its hateful and extreme political commentary, and later to Pastebin, a text storage site, to Twitter and to far-right extremist channels on Telegram, a messaging app.

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.

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.
