Selling elephant ivory—a hard white material from elephant tusks, for which elephants are often killed—is illegal. Selling ivory collected from the remains of extinct Mammoths, however, is—somehow—not. Because the two are hard to tell apart, illegal traders are slipping under the radar by mixing elephant ivory with legally traded mammoth ivory. A new forensic tool, however, might soon put an end to this nefarious trick.
Wildlife forensic scientists in China suggest that authorities can differentiate elephant ivory from mammoth ivory by analyzing stable isotopes (forms of an element that don’t break down over time). If this approach becomes widely adopted, it could serve as a quick sample screening before the application of more expensive and time-consuming methods.
“Mammoth ivory costs a fraction of the price of elephant ivory, but the two are considered completely different materials by carvers and experts, because mammoth ivory usually lacks the deep, creamy white color of elephant ivory,” Pavel Toropov, a University of Hong Kong researcher and a co-author of the study published today in the journal Frontiers, said in a Frontiers statement. “One trader compared them to a ‘Lamborghini and a Ford.’ Mammoth ivory cannot be a real substitute for elephant ivory, but its value may lie in providing a legal cover for elephant ivory.”
Currently, the most accurate way to tell the two ivories apart is via molecular analysis (studying molecules) or radiocarbon dating (a technique to date organic material), both of which are expensive and time consuming.
Isotope ratios vary depending on factors like environment. Since Ice Age mammoths preserved in high-latitude Siberian permafrost lived in a completely different habitat from today’s tropical elephants, the isotope ratios in their tusks should be different. Within this context, Toropov and his team decided to investigate whether analyzing these differences could provide a better method to distinguish between the two types of ivory.
The team conducted stable isotope analyses on 44 pieces of elephant ivory and 35 pieces of mammoth ivory, specifically studying the stable isotope ratios of carbon, hydrogen, nitrogen, oxygen, and sulfur. While this approach revealed notable overlap for carbon, nitrogen, and sulfur isotope ratios between the two ivories, the researchers documented very little overlap in the elephant and mammoth isotope ratios for oxygen and none for hydrogen.
“This is because the elements of water drunk by mammoths in high-latitude regions such as Siberia have distinct isotope signatures compared to the elements of the water ingested by elephants in tropical latitudes,” explained first author Maria Santos, also a researcher from the University of Hong Kong. Simply put, analyzing the stable isotope ratios of oxygen and hydrogen in a suspected ivory object is an effective way to determine whether it came from an elephant or a mammoth.
While more research is needed before this approach can be used in a court case, “we hope that the protocol described in our study will be applied to screen large batches of supposedly mammoth ivory objects,” Santos added. “Samples that have an isotopic signature of elephant ivory can then be tested with more expensive and time-consuming methods, such as radiocarbon dating. This could help combat the illegal ivory trade more effectively and close the potential laundering loophole.”
The way I see it, there’s an even simpler solution: Make all ivory illegal.

![The running list: major tech layoffs in 2026 where employers cited AI | TechCrunch
Oracle disclosed Monday that it has reduced its workforce by 21,000 employees over the past 12 months, a decline of 13%, which means more cuts than was previously known, including jobs eliminated because of AI. “The adoption and deployment of AI technologies across our operations have resulted, and may continue to result, in reductions to our workforce,” the company said in an annual financial regulatory filing.
The revelation puts new numbers to what feels to many in the tech industry like an epidemic: companies reporting record revenues while simultaneously culling their workforces, pointing to AI as both the engine of growth and the reason for the cuts. Tech layoffs hit their highest single month in years in May, and AI was the most-cited reason, according to outplacement firm Challenger, Gray & Christmas.
We recently wrote about why that rationale is something companies may want to rethink, not least because for many of these companies, the headcount they’re now cutting was hired during the pandemic hiring surge, raising questions about what’s really going on. Below, a running look — in reverse chronological order — at the bigger tech companies that have announced significant layoffs this year with AI as a stated factor.
GitLab — June 3, 2026. In one of the most recent cuts on this list, GitLab laid off roughly 350 workers, about 14% of its staff, to fund AI infrastructure investment and handle surging traffic from AI workflows. CEO Bill Staples said agentic workloads are “pushing competitors to the brink” and that the company had begun a “generational rebuild” of its core infrastructure to support what he called 100x growth requirements. GitLab is exiting 22 countries, flattening management layers, and partnering with an unspecified AI lab to rebuild its platform for agent-scale workloads. The company reported first-quarter revenue of 4 million, up 23% year-over-year, and expects to incur to million in restructuring costs.
Google — ongoing through May. Alphabet’s Google has quietly cut employees across its Cloud division, including its Threat Intelligence Group and Mandiant-linked cybersecurity staff, even as Cloud revenue grew 63% to exceed billion for the first time and its backlog nearly doubled to over 0 billion. Over the past year, Google has cut more than a third of the managers overseeing small teams — 35% fewer managers with fewer direct reports. Unlike most companies on this list, Google has never announced a single overall number — the cuts have come through a rolling performance review process, a voluntary buyout program, and structural reorganizations, with outside estimates putting the 2026 total at between 1,500 and 3,000+ engineers.
Intuit — May 20, 2026. Intuit announced plans to eliminate roughly 3,000 jobs — about 17% of its total workforce — in a restructuring centered on reducing complexity and reallocating resources toward AI. CEO Sasan Goodarzi reportedly told staff the company is reducing complexity and simplifying the structure, so it can deliver better products.
Meta — May 20-21, 2026. Meta laid off about 8,000 employees, roughly 10% of its workforce, while moving about 7,000 employees into new AI-focused roles (that they reportedly hate). Zuckerberg told staff the cuts were necessary because “success isn’t a given” in AI.
Cisco — May 14, 2026. Cisco announced it’s cutting nearly 4,000 jobs, about 5% of its workforce, despite reporting better-than-expected profit and revenue. CFO Mark Patterson said: “This was really not a savings-driven restructure… this is more [about] realigning … resources around silicon, optics, security and AI.”
Cloudflare — May 7-8, 2026. Cloudflare cut about 20% of its workforce (1,100 people), reporting quarterly revenue of 9.8 million, up 34% year-over-year and the highest single quarter in company history. CEO Matthew Prince wrote that “the vast majority of those we laid off last week were measurers” — middle management, finance, legal, internal auditing, and revenue recognition.
General Motors — May 12, 2026. GM eliminated 500 to 600 jobs, largely in IT roles in Austin, Texas, and Warren, Michigan, saying it was reevaluating its workforce needs amid uncertain market conditions. A person familiar with the cuts told CNBC that AI played a role in the decision but that it wasn’t the only reason. GM’s statement said it was “transforming its Information Technology organization to better position the company for the future.” Despite the cuts, the company still had roughly 80 open IT positions, including roles in AI, motorsports, and autonomous vehicles.
Coinbase — May 5, 2026. The crypto exchange said it was cutting about 700 employees, or 14% of its staff, as part of a restructuring aimed at addressing market volatility and increasing AI efficiency. The company flattened its organizational structure to five layers below the CEO and COO, and said it would experiment with “one-person teams” combining engineering, design, and product roles. CEO Brian Armstrong wrote that AI had changed the pace of work dramatically — “engineers use AI to ship in days what used to take a team weeks” — and that the company needed to “leverage AI across every facet of our jobs.”
PayPal — May 5, 2026. PayPal announced plans to cut around 20% of its workforce over the next two to three years — north of 4,500 jobs — as part of a turnaround strategy centered on AI adoption and organizational simplification. CEO Enrique Lores told investors the company would “aggressively adopt AI” in its development processes and formed a new “AI transformation and simplification” team reporting directly to him, tasked with redesigning the company’s processes “function by function.” Lores framed the cuts as removing organizational layers, and said AI would extend well beyond coding into customer service, support operations, and risk management.Microsoft — April-May 2026. Microsoft offered buyouts structured as voluntary separations, without disclosing how many employees these would impact. CFO Amy Hood said total headcount declined year-over-year in fiscal Q3, and is expected to keep declining as the company focuses on “building high-performing teams that operate with pace and agility” amid rising AI investment.
Snap — April 16, 2026. Snap cut roughly 16% of its global workforce — about 1,000 full-time employees — and closed more than 300 open roles, with CEO Evan Spiegel citing AI advancements as a key driver. “Rapid advancements in artificial intelligence enable our teams to reduce repetitive work, increase velocity, and better support our community, partners, and advertisers,” Spiegel wrote in a memo filed with the SEC. The company said it had already seen small squads using AI tools to drive progress across Snapchat+, ad platform performance, and infrastructure efficiency.
IBM — rolling through 2026. Between Q4 2025 cuts and April 2026 Red Hat engineering reductions, estimates range from 3,000 to 9,000 U.S. positions eliminated, bringing IBM’s cumulative total since September 2024 above 15,000. Bloomberg reported IBM plans to triple its U.S. entry-level hiring for AI and hybrid-cloud roles, even as roughly 200 HR positions were replaced by AI agents. An IBM spokesperson described the Q4 2025 round as a routine rebalancing affecting “a low single-digit percentage” of its global workforce.
Atlassian — March 11, 2026. Atlassian cut about 1,600 jobs (10% of its workforce) to “rebalance” toward AI and enterprise sales, even as shares rose nearly 2% on the news. CEO Mike Cannon-Brookes said: “Our approach is not ‘AI replaces people.’ But it would be disingenuous to pretend AI doesn’t change the mix of skills we need or the number of roles required in certain areas. It does.” Dell — Jan 30 (though disclosed in March 2026). Dell’s total workforce fell about 10% in fiscal 2026 — roughly 11,000 jobs — to about 97,000 employees from 108,000 a year earlier, with 9 million spent on severance. The cuts came as Dell projected its AI-optimized server revenue could double in fiscal 2027.
Oracle — March 5-31, 2026. As noted above, Oracle began telling employees it would be cutting thousands of jobs via terminal emails. The cuts came even as Oracle posted .7 billion in quarterly net income, up 27% year-over-year, with remaining performance obligations up 325% to 3 billion — savings redirected toward AI data centers. The cuts that would later total 21,000 over 12 months, as Oracle disclosed in its June 22 annual filing.
Block — February 26-27, 2026. Jack Dorsey’s Block cut 4,000 jobs — nearly half its workforce, down to under 6,000 from over 10,000. Dorsey wrote on X: “We’re already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company.” He added: “I think most companies are late. Within the next year, I believe the majority of companies will reach the same conclusion and make similar structural changes.” Salesforce — February 10, 2026. Salesforce laid off fewer than 1,000 employees across marketing, product management, data analytics, and its Agentforce AI unit. The company told Fortune, “Because of the benefits and efficiencies of Agentforce, we’ve seen the number of support cases we handle decline and we no longer need to actively backfill support engineer roles.” This followed an earlier cut of about 4,000 customer-support roles, shrinking that team from roughly 9,000 to 5,000, with CEO Marc Benioff saying the company needed “less heads” because AI agents handle the work. Amazon — January 28, 2026. Amazon cut 16,000 corporate jobs, following 14,000 cuts in October 2025 — about 9% of its corporate workforce in three months. The company said it was part of “strengthen[ing] our organization by reducing layers, increasing ownership, and removing bureaucracy.” CEO Andy Jassy had said in June 2025 that, “As we roll out more generative AI and agents, it should change the way our work is done. We will need fewer people doing some of the jobs that are being done today… in the next few years, we expect that this will reduce our total corporate workforce as we get efficiency gains from using AI extensively across the company.”
