New “unprecedented” animations of the Earth show how the planet’s surface has shifted and changed over the past 100 million years. 

These animations are the most detailed view of the history of Earth’s topography ever, depicting the rise of mountains, the development of basins, and the transport of large masses of sediments around the globe through erosion.  

The animations show the movements of tectonic plates, the large rafts of crust that bump up against each other to form mountain ranges and pull apart to form ocean basins. When these plates dive into the mantle, or Earth’s middle layer, at subduction zones they give rise to planet-shaping volcanoes and earthquakes. But there are other forces shaping the surface, too: Precipitation erodes away the surface, while the rate of weathering alters levels of carbon dioxide in the air, creating a feedback loop that links the land to the atmosphere. 

“While the dance of the continents has been studied extensively, we are still limited in our understanding and representation of how the Earth’s surface has evolved,” said Tristan Salles (opens in new tab) , a senior lecturer in geosciences at the University of Sydney and the lead author of a new paper describing the model, which was published March 2 in the journal Science (opens in new tab) .

“What we bring with this new model,” Salles wrote in an email to Live Science, “is a way to evaluate how this surface has changed (globally and over geological time scales) shaped by its interactions with the atmosphere, the hydrosphere, the tectonic and mantle dynamics.”

The model begins 100 million years ago in the midst of the breakup of the supercontinent Pangaea, which started to occur around 200 million years ago. In the beginning of the animation, the continents that will become Africa and South America are already recognizable, with the Northern Hemisphere continents coming together tens of millions of years later. Blue shows the flow of water, while red shows the intensity of the deposition of new sediments by erosion. 

“This unprecedented high-resolution model of Earth’s recent past will equip geoscientists with a more complete and dynamic understanding of the Earth’s surface,” study co-author Laurent Husson (opens in new tab) , a geologist at the Institute of Earth Sciences (ISTerre) in Grenoble, France, said in a statement (opens in new tab) .

Putting together all of these different pressures on the evolution of Earth, from the movements of the plates to the flow of water to the slow changes in the mantle, provides a new way to ask questions about everything from the regulation of the climate to the ways the circulation of the atmosphere affect erosion on land. Related Stories —Oldest evidence of tectonic plates unearthed, sealed in ancient crystals

The researchers found that the rate of sediment movement across the globe was likely much larger than what scientists believe based on observation, probably because the sedimentary record is fragmented. Overall erosion rates have been fairly steady for the past 100 million years, Salles said, but there have been changes in whether the sediment ends up trapped in low-elevation basins on land or ultimately flows out to sea. For example, there was a doubling of sediment flow to the oceans between about 60 million and 30 million years ago, which was likely associated with the rise of the Himalaya Mountains and the Tibetan Plateau, the researchers wrote. 

Such nuances could be important, Salles said. For example, some of the earliest life formed in shallow marine environments, where microorganisms harnessed photosynthesis for the first time and left behind mineralized formations known as stromatolites. 

“It is thought that sedimentation flux may have provided a source of nutrients to these early organisms, allowing them to thrive and evolve over time,” Salles said. “We envision that our model could be used to test such long-standing hypotheses regarding the origin of life on Earth.”

Crypto stocks down, IPOs punted amid tariff tumult

Crypto stocks down, IPOs punted amid tariff tumult

Cryptocurrency firms felt the heat from US President Donald Trump’s sweeping tariff rollout this week as market turbulence sent share prices tumbling and foiled initial public offering (IPO) plans. 

From exchanges to Bitcoin (BTC) miners, crypto stocks suffered as much, if not more, than shares of other companies — despite the industry’s warm relationship with the US president. 

On April 2, Trump announced he was placing tariffs of at least 10% on practically all imports into the United States and adding additional “reciprocal” tariffs on some 57 countries. 

Since then, major US stock indices — including the S&P 500 and Nasdaq — tumbled by roughly 10% as traders braced for a looming trade war.

Sharp selloffs

Crypto exchange Coinbase — a prominent ally of Trump during the November US elections — experienced a similarly severe sell-off, with its stock price dropping by roughly 12% during the same period, according to data from Google Finance.

Bitcoin miners are also taking a hit. The CoinShares Crypto Miners ETF (WGMI) — which tracks a diverse basket of Bitcoin mining stocks — has lost roughly 13% of its value since immediately prior to Trump’s April 2 announcement, according to data from Morningstar. 

Even Strategy, one of the best-performing stocks of 2024, wasn’t immune. Its share price has fallen by around 6% on the news, Google Finance data showed.

According to Reuters, investment bank JPMorgan has raised its estimated odds of a global economic recession in 2025 to 60% from 40% previously. 

“Disruptive U.S. policies have been recognized as the biggest risk to the global outlook all year,” JP Morgan reportedly said.

“The effect … is likely to be magnified through (tariff) retaliation, a slide in U.S. business sentiment and supply-chain disruptions.”

IPO delays

The impact of US tariffs hasn’t been limited to stock price volatility. Stablecoin issuer Circle has reportedly paused plans for a 2025 IPO, citing market turbulence. 

According to The Wall Street Journal, Circle is “waiting anxiously” before taking further steps after filing to take the company public on April 1. 

It is among several companies — including fintech Klarna and ticketing service StubHub — reportedly considering altering or shelving IPO plans. 

One exception may be Bitcoin itself, which some analysts say is finally “decoupling” from the broader market.

Bitcoin’s spot price has held above $82,000 this week, even as US equities markets collapsed.

Brazilian court authorizes crypto seizure for debt collection — Report

Brazilian court authorizes crypto seizure for debt collection — Report

Brazilian judges have been authorized to seize cryptocurrency assets from debtors who owe money and are behind on their payments, signaling a growing recognition that digital assets can be both a form of payment and a store of value.

According to local media reports, the Third Panel of Brazil’s Superior Court of Justice unanimously authorized judges to send letters to cryptocurrency brokers informing them about their intent to seize an account holder’s assets to repay creditors.

The report was confirmed by the Superior Court of Justice, which issued a notice on its website.

The decision was reached unanimously by the Third Panel, which reviewed a case brought forward by a creditor.

“Although they are not legal tender, crypto assets can be used as a form of payment and as a store of value,” a translated version of the Superior Court of Justice’s memo read.

Under existing rules, Brazilian judges are allowed to freeze bank accounts and order fund withdrawals, even without a debtor’s knowledge, should they rule that a creditor is owed money.

Following the recent decision, crypto assets now fall under the same purview. 

Minister Ricardo Villas Bôas Cueva, who voted in the five-person panel, said cryptocurrencies still lack formal regulation in Brazil but noted certain bills have recognized the asset class as “a digital representation of value.”

Despite regulatory uncertainty, Brazil is a major hub for crypto

Although Brazil still lacks an overarching framework for digital assets, with the country’s central bank divvying up the regulatory processes into phases, crypto adoption is surging across the country.

Brazil ranks second among all Latin American countries in terms of “crypto value received,” which is a key benchmark for adoption, according to an October report by Chainalysis.

Earlier this year, crypto exchange Binance was granted approval to operate in the country after it acquired a São Paulo-based investment company. 

A Binance executive told Cointelegraph at the time that Brazil was making “significant strides” in regulating the industry and expects a comprehensive framework to be finalized “by mid-year.”

Nevertheless, not all of Brazil’s regulatory proposals have been favorable for the industry.

In December, the country’s central bank proposed banning stablecoin transactions on self-custodial wallets at a time when more locals were using dollar-pegged tokens to hedge against the devaluation of the Brazilian real.

Industry observers told Cointelegraph at the time that such a ban would be difficult to enforce.

“Governments can regulate centralized exchanges, but P2P transactions and decentralized platforms are much harder to control, which means the ban would likely only affect part of the ecosystem,” said Lucien Bourdon, an analyst with Trezor.

This fund most recently provided aid for communities affected by the recent Los Angeles wildfires, assistance to the Special Forces Charitable Trust (SFCT) in North Carolina following severe hurricanes, and support for non-profits engaged in hurricane preparedness in Florida and the Gulf Coast. Per Jodi Burns, CEO of the Special Forces Charitable Trust:

In the wake of devastating storms in Western North Carolina, reliable power was a critical need for the families we serve. Thanks to EcoFlow’s generous donation of generators, we were able to provide immediate relief, ensuring these families and their communities had access to power when they needed it most. We are so impressed with EcoFlow’s commitment to disaster response through their ‘Power for All’ program. It has made a tangible impact, and we are deeply grateful for their support and partnership in helping these families recover and rebuild.

In 2024, the US experienced 27 weather and climate events, each causing losses exceeding $1 billion, marking the second-highest annual total on record, according to National Centers for Environmental Information. The increasing frequency and severity of natural disasters underscore the critical need for reliable and timely power solutions during emergencies, much like EcoFlow and its members are helping provide through the “Power For All” initiative.

To support new and existing EcoFlow members, the company is celebrating its third annual Member’s Festival throughout April to offer a do-not-miss discount on its products and donate a portion of all sales to the “Power for All” fund to provide rescue power to those in need in the future.
