More than 1.2 million years ago, an unknown group of human relatives may have created sharp hand axes from volcanic glass in a “stone-tool workshop” in what is now Ethiopia, a new study finds.

This discovery suggests that ancient human relatives may have regularly manufactured stone artifacts in a methodical way more than a half-million years earlier than the previous record, which dates to about 500,000 years ago in France and England.

Because it requires skill and knowledge, stone tool use among early hominins, the group that includes humans and the extinct species more closely related to humans than any other animal, can offer a window into the evolution of the human mind. A key advance in stone tool creation was the emergence of so-called workshops. At these sites, archaeologists can see evidence of hominins methodically and repeatedly crafting stone artifacts.

The newly analyzed trove of obsidian tools may be the oldest stone-tool workshop run by hominins on record. “This is very new in human evolution,” study first author Margherita Mussi (opens in new tab) , an archaeologist at the Sapienza University of Rome and director of the Italo-Spanish archeological mission at Melka Kunture and Balchit, a World Heritage site in Ethiopia, told Live Science.Oldest known hominin workshop

In the new study, the researchers investigated a cluster of sites known as Melka Kunture, located along the upper Awash River valley of Ethiopia. The Awash valley has yielded some of the best known examples of early hominin fossils, such as the famous ancient relative of humanity dubbed “Lucy.”

The scientists focused on 575 artifacts made of obsidian at a site known as Simbiro III in Melka Kunture. These ancient tools came from a layer of sand dubbed Level C, which fossil and geological data suggest is more than 1.2 million years old. 

These obsidian artifacts included more than 30 hand axes, or teardrop-shaped stone tools, averaging about 4.5 inches (11.5 centimeters) long and 0.7 pounds (0.3 kilograms). Ancient humans and other hominins may have used them for chopping, scraping, butchering and digging.

Obsidian proved far more rare at Simbiro III before and after Level C, and scarce in other Melka Kunture sites. The new excavations also revealed that Level C experienced seasonal flooding, with a meandering river likely depositing obsidian rocks at the site during this time of Level C. Obsidian axes from this level were far more regular in shape and size, which suggests mastery of the manufacturing technique.

Ancient hominins “are very often depicted as barely surviving, struggling with a hostile and changing environment,” Mussi said in an email from the field in Melka Kunture. “Here we prove instead that they were clever individuals, who did not miss the opportunity of testing any resource they discovered.”

This nearly exclusive use of obsidian at Level C of Simbiro III is unusual during the Early Stone Age, which ranged from about 3.3 million to 300,000 years ago, the researchers said. Obsidian tools can possess extraordinarily sharp cutting edges, but the volcanic glass is brittle and difficult to craft without smashing. As such, obsidian generally only found extensive use in stone tool manufacture beginning from the Middle Stone Age, which ranged from about 300,000 to 50,000 years ago, they said.

“The idea that ancient hominins of this era valued and made special use of obsidian as a material makes a lot of sense,” John Hawks (opens in new tab) , a paleoanthropologist at the University of Wisconsin–Madison who did not take part in this research, told Live Science. “Obsidian is widely recognized as uniquely valuable among natural materials for flaking sharp-edged tools; it is also highly special in appearance. Some historic cultures have used obsidian and traded it across distances of hundreds of miles.”

That trading may have gone on farther back than widely acknowledged.

“There has been evidence since the 1970s (opens in new tab) that obsidian may have been transported across long distances as early as 1.4 million years ago,” Hawks said. “That evidence has not been replicated by more recent excavation work, but the new report by Mussi and coworkers may be a step in that direction.”

It remains uncertain which hominin may have created these artifacts. Previously, at other Melka Kunture sites, researchers have discovered hominin remains about 1.66 million years old that may have been Homo erectus, and fossils about 1 million years old that may have been Homo heidelbergensis, Mussi said. H. erectus is the oldest known early human (opens in new tab) to possess body proportions similar to modern humans, whereas H. heidelbergensis may have been a common ancestor (opens in new tab) of both modern humans and Neanderthals, according to the Smithsonian. Since the age of Level C at Simbiro III is more than 1.2 million years old, the hominins that made the obsidian hand axes there may have been closer in nature to H. erectus, Mussi said.

The scientists detailed their findings Jan. 19 in the journal Nature Ecology and Evolution (opens in new tab) .

Why Meta had to ‘bend the knee to Trump’ ahead of his inauguration

Why Meta had to 'bend the knee to Trump' ahead of his inauguration

Mark Zuckerberg’s announcement this week that Meta would pivot its moderation policies to allow more “free expression” was widely viewed as the company’s latest effort to appease President-elect Donald Trump. 

More than any of its Silicon Valley peers, Meta has taken numerous public steps to make amends with Trump since his election victory in November.

That follows a highly contentious four years between the two during Trump’s first term in office, which ended with Facebook — similar to other social media companies — banning Trump from its platform.

As recently as March, Trump was using his preferred nickname of “Zuckerschmuck” when talking about Meta’s CEO and declaring that Facebook was an “enemy of the people.”

With Meta now positioning itself to be a key player in artificial intelligence, Zuckerberg recognizes the need for White House support as his company builds data centers and pursues policies that will allow it to fulfill its lofty ambitions, according to people familiar with the company’s plans who asked not to be named because they weren’t authorized to speak on the matter.

“Even though Facebook is as powerful as it is, it still had to bend the knee to Trump,” said Brian Boland, a former Facebook vice president, who left the company in 2020.

Meta declined to comment for this article.

In Tuesday’s announcement, Zuckerberg said Meta will end third-party fact-checking, remove restrictions on topics such as immigration and gender identity and bring political content back to users’ feeds. Zuckerberg pitched the sweeping policy changes as key to stabilizing Meta’s content-moderation apparatus, which he said had “reached a point where it’s just too many mistakes and too much censorship.”

The policy change was the latest strategic shift Meta has taken to buddy up with Trump and Republicans since Election Day.

A day earlier, Meta announced that UFC CEO Dana White, a longtime Trump friend, is joining the company’s board.

And last week, Meta announced that it was replacing Nick Clegg, its president of global affairs, with Joel Kaplan, who had been the company’s policy vice president. Clegg previously had a career in British politics with the Liberal Democrats party, including as a deputy prime minister, while Kaplan was a White House deputy chief of staff under former President George W. Bush.

Kaplan, who joined Meta in 2011 when it was still known as Facebook, has longstanding ties to the Republican Party and once worked as a law clerk for the late conservative Supreme Court Justice Antonin Scalia. In December, Kaplan posted photos on Facebook of himself with Vice President-elect JD Vance and Trump during their visit to the New York Stock Exchange.

Many Meta employees criticized the policy change internally, with some saying the company is absolving itself of its responsibility to create a safe platform. Current and former employees also expressed concern that marginalized communities could face more online abuse due to the new policy, which is set to take effect over the coming weeks. 

Despite the backlash from employees, people familiar with the company’s thinking said Meta is more willing to make these kinds of moves after laying off 21,000 employees, or nearly a quarter of its workforce, in 2022 and 2023. 

Those cuts affected much of Meta’s civic integrity and trust and safety teams. The civic integrity group was the closest thing the company had to a white-collar union, with members willing to push back against certain policy decisions, former employees said. Since the job cuts, Zuckerberg faces less friction when making broad policy changes, the people said.

Zuckerberg’s overtures to Trump began in the months leading up to the election.

Following the first assassination attempt on Trump in July, Zuckerberg called the photo of Trump raising his fist with blood running down his face “one of the most badass things I’ve ever seen in my life.”

A month later, Zuckerberg penned a letter to the House Judiciary Committee alleging that the Biden administration had pressured Meta’s teams to censor certain Covid-19 content.

“I believe the government pressure was wrong, and I regret that we were not more outspoken about it,” he wrote. 

After Trump’s presidential victory, Zuckerberg joined several other technology executives who visited the president-elect’s Mar-a-Lago resort in Florida. Meta also donated $1 million to Trump’s inaugural fund.

On Friday, Meta revealed to its workforce in a memo obtained by CNBC that it intends to shutter several internal programs related to diversity and inclusion in its hiring process, representing another Trump-friendly move.

The previous day, some details of the company’s new relaxed content-moderation guidelines were published by the news site The Intercept, showing the kind of offensive rhetoric that Meta’s new policy would now allow, including statements such as “Migrants are no better than vomit” and “I bet Jorge’s the one who stole my backpack after track practice today. Immigrants are all thieves.”

Recalibrating for Trump

Zuckerberg, who has been dragged to Washington eight times to testify before congressional committees during the last two administrations, wants to be perceived as someone who can work with Trump and the Republican Party, people familiar with the matter said.

Though Meta’s content-policy updates caught many of its employees and fact-checking partners by surprise, a small group of executives were formulating the plans in the aftermath of the U.S. election results. By New Year’s Day, leadership began planning the public announcements of its policy change, the people said. 

Meta typically undergoes major “recalibrations” after prominent U.S. elections, said Katie Harbath, a former Facebook policy director and CEO of tech consulting firm Anchor Change. When the country undergoes a change in power, Meta adjusts its policies to best suit its business and reputational needs based on the political landscape, Harbath said. 

“In 2028, they’ll recalibrate again,” she said.

After the 2016 election and Trump’s first victory, for example, Zuckerberg toured the U.S. to meet people in states he hadn’t previously visited. He published a 6,000-word manifesto emphasizing the need for Facebook to build more community.

The social media company faced harsh criticism about fake news and Russian election interference on its platforms after the 2016 election.

Following the 2020 election, during the heart of the pandemic, Meta took a harder stand on Covid-19 content, with a policy executive saying in 2021 that the “amount of COVID-19 vaccine misinformation that violates our policies is too much by our standards.” Those efforts may have appeased the Biden administration, but it drew the ire of Republicans.

Meta is once again reacting to the moment, Harbath said.

“There wasn’t a business risk here in Silicon Valley to be more right-leaning,” Harbath said.

While Trump has offered few specific policy proposals for his second administration, Meta has plenty at stake.

The White House could create more relaxed AI regulations compared with those in the European Union, where Meta says harsh restrictions have resulted in the company not releasing some of its more advanced AI technologies. Meta, like other tech giants, also needs more massive data centers and cutting-edge computer chips to help train and run their advanced AI models.

“There’s a business benefit to having Republicans win, because they are traditionally less regulatory,” Harbath said.

Meta isn’t alone in trying to cozy up to Trump. But the extreme measures the company is taking reflects a particular level of animus expressed by Trump over the years.

Trump has accused Meta of censorship and has expressed resentment over the company’s two-year suspension of his Facebook and Instagram accounts following the Jan. 6 attack on the Capitol.

In July 2024, Trump posted on Truth Social that he intended to “pursue Election Fraudsters at levels never seen before, and they will be sent to prison for long periods of time,” adding “ZUCKERBUCKS, be careful!” Trump reiterated that statement in his book, “Save America,” writing that Zuckerberg plotted against him during the 2020 election and that the Meta CEO would “spend the rest of his life in prison” if it happened again.

Meta spends $14 million annually on providing personal security for Zuckerberg and his family, according to the company’s 2024 proxy statement. As part of that security, the company analyzes any threats or perceived threats against its CEO, according to a person familiar with the matter. Those threats are cataloged, analyzed and dissected by Meta’s multitude of security teams.

After Trump’s comments, Meta’s security teams analyzed how Trump could weaponize the Justice Department and the country’s intelligence agencies against Zuckerberg and what it would cost the company to defend its CEO against a sitting president, said the person, who asked not to be named because of confidentiality.

Meta’s efforts to appease the incoming president bring their own risks.

After Zuckerberg announced the new speech policy Tuesday, Boland, the former executive, was among a number of users who took to Meta’s Threads service to tell their followers that they were quitting Facebook. 

“Last post before deleting,” Boland wrote in his post.

Before the post could be seen by any of his Threads followers, Meta’s content moderation system had taken it down, citing cybersecurity reasons. 

Boland told CNBC in an interview that he couldn’t help but chuckle at the situation. 

“It’s deeply ironic,” Boland said.

LA fires: Data and videos reveal scale of ‘most destructive’ blazes in modern US history

LA fires: Data and videos reveal scale of 'most destructive' blazes in modern US history

The fires that have been raging in Los Angeles County this week may be the “most destructive” in modern US history.

In just three days, the blazes have covered tens of thousands of acres of land and could potentially have an economic impact of up to $150bn (£123bn), according to private forecaster Accuweather.

Sky News has used a combination of open-source techniques, data analysis, satellite imagery and social media footage to analyse how and why the fires started, and work out the estimated economic and environmental cost.

More than 1,000 structures have been damaged so far, local officials have estimated. The real figure is likely to be much higher.

“In fact, it’s likely that perhaps 15,000 or even more structures have been destroyed,” said Jonathan Porter, chief meteorologist at Accuweather.

These include some of the country’s most expensive real estate, as well as critical infrastructure.

Accuweather has estimated the fires could have a total damage and economic loss of between $135bn and $150bn.

“It’s clear this is going to be the most destructive wildfire in California history, and likely the most destructive wildfire in modern US history,” said Mr Porter.

“That is our estimate based upon what has occurred thus far, plus some considerations for the near-term impacts of the fires,” he added.

The calculations were made using a wide variety of data inputs, from property damage and evacuation efforts, to the longer-term negative impacts from job and wage losses as well as a decline in tourism to the area.

The Palisades fire, which has burned at least 20,000 acres of land, has been the biggest so far.

Satellite imagery and social media videos indicate the fire was first visible in the area around Skull Rock, part of a 4.5 mile hiking trail, northeast of the upscale Pacific Palisades neighbourhood.

These videos were taken by hikers on the route at around 10.30am on Tuesday 7 January, when the fire began spreading.

At about the same time, this footage of a plane landing at Los Angeles International Airport was captured. A growing cloud of smoke is visible in the hills in the background – the same area where the hikers filmed their videos.

The area’s high winds and dry weather accelerated the speed that the fire has spread. By Tuesday night, Eaton fire sparked in a forested area north of downtown LA, and Hurst fire broke out in Sylmar, a suburban neighbourhood north of San Fernando, after a brush fire.

These images from NASA’s Black Marble tool that detects light sources on the ground show how much the Palisades and Eaton fires grew in less than 24 hours.

 

On Tuesday, the Palisades fire had covered 772 acres. At the time of publication of Friday, the fire had grown to cover nearly 20,500 acres, some 26.5 times its initial size.

The Palisades fire was the first to spark, but others erupted over the following days.

At around 1pm on Wednesday afternoon, the Lidia fire was first reported in Acton, next to the Angeles National Forest north of LA. Smaller than the others, firefighters managed to contain the blaze by 75% on Friday.

On Thursday, the Kenneth fire was reported at 2.40pm local time, according to Ventura County Fire Department, near a place called Victory Trailhead at the border of Ventura and Los Angeles counties.

This footage from a fire-monitoring camera in Simi Valley shows plumes of smoke billowing from the Kenneth fire.

Sky News analysed infrared satellite imagery to show how these fires grew all across LA.

The largest fires are still far from being contained, and have prompted thousands of residents to flee their homes as officials continued to keep large areas under evacuation orders. It’s unclear when they’ll be able to return.

“This is a tremendous loss that is going to result in many people and businesses needing a lot of help, as they begin the very slow process of putting their lives back together and rebuilding,” said Mr Porter.

“This is going to be an event that is going to likely take some people and businesses, perhaps a decade to recover from this fully.”
