If I had a hammer... it might actually be a rhino tooth

One way archaeologists learn how ancient people, including Neanderthals, did things is to attempt to do those things themselves, a process called experimental archaeology. Normally, that involves making stone tools, butchering deer, or distilling birch tar. But in a new study, it meant doing very destructive things to teeth from one of the world’s most carefully protected animals.

That's because the archeologists suspected that Neanderthals once used rhino teeth as tools. By using the teeth to make stone tools, the researchers demonstrated that Neanderthals probably did the same thing, adding to what we know about the wide range of items in their toolkits.

We need to hit some rhino teeth with rocks for science

Some Neanderthal archaeological sites in Europe and Asia seem to have many more rhinoceros teeth lying around than you’d expect. We know Neanderthals hunted a now-extinct species of rhinoceros in Europe and eastern Asia, but the people who had inhabited these sites looked like they had been collecting rhino teeth for some reason.

Feds failing in bid to take a supercomputer from a climate research center

Feds failing in bid to take a supercomputer from a climate research center

fivenewscrypto    juin 04, 2026   

In December, the Trump administration abruptly announced it would shut down the National Center for Atmospheric Research (NCAR), a Boulder, Colorado-based facility that helps researchers perform studies of weather, climate, atmospheric chemistry, and more. The news came as a shock, given that the government had never identified serious deficiencies in the management of NCAR and its associated supercomputing center in Wyoming.

Nevertheless, the government ordered the University Consortium for Atmospheric Research (UCAR), which manages NCAR on behalf of the National Science Foundation, to help it prepare to transfer the Wyoming facility to a different operator. UCAR sued the government and, on Monday, won a preliminary injunction that places the transfer of the facility on hold.

Is that your final decision?

NCAR is what is termed a "Federally-Funded Research and Development Center" meant to support researchers in the academic community. Rather than having its own research agenda, it provides facilities, equipment, and expertise to support projects that are too large or complex for researchers to pursue on their own. NCAR has been around since the early 1960s and has become a critical resource for the global atmospheric science community.

Mathematicians warn of AI threats to profession as industry encroaches

Mathematicians warn of AI threats to profession as industry encroaches

fivenewscrypto    juin 03, 2026   

Mathematicians warned against rising tech industry influence in a declaration describing the many challenges that AI poses to mathematics research. The timing of the declaration comes two weeks after OpenAI publicized one of its AI models as having disproved an 80-year-old mathematical conjecture in geometry.

The declaration was developed by a working group of 16 researchers over eight months following a conference held at Leiden University in the Netherlands in September 2025. Published on June 2, 2026, the resulting Leiden Declaration on Artificial Intelligence and Mathematics has been endorsed by the International Mathematical Union—the international non-governmental organization that hosts conferences and oversees the most prestigious prizes in mathematics such as the Fields Medal.

“Mathematicians should find it quite striking that tech companies are suddenly interested in their work,” said Kevin Buzzard, a mathematician at Imperial College London, in a statement. “The Leiden Declaration is a well-thought-through response to what is currently happening, as AI continues to disrupt this space.”

Android phones will soon be able to detect spoofed calls and impersonation scams

Android phones will soon be able to detect spoofed calls and impersonation scams

fivenewscrypto    juin 03, 2026   

We're expecting Android 17 to begin rolling out later this month, but first, Google has a batch of updates for the wider Android device ecosystem. As usual, some of the new features are limited to specific devices, and others require using Google's apps. But if you don't mind the latter, you can get automated protection from the growing threat of deepfake phone scams.

According to Google, "impersonation fraud" is one of the most common types of financial scams. The FTC tracked almost $3 billion in losses from such scams during 2024, and the improvements in AI voice cloning tools more recently are making the schemes easier to pull off. The voice models are becoming so capable that it can be difficult to identify a fake caller even when an AI is imitating someone you talk to every day.

Google's solution is an expansion of the system it debuted last month for verified financial calls. Now, a similar feature will work with anyone in your contacts. Many of the most effective deepfake scams involve spoofing a contact's number, which makes the call look more legitimate when your phone lights up. Victims of these scams are then greeted by an accurate re-creation of the person's voice spinning a yarn that involves an urgent need for cash.

The truth lies in the past in Silo S3 trailer

The truth lies in the past in Silo S3 trailer

fivenewscrypto    juin 03, 2026   

In April, we got a short teaser for the third season of Silo, the critically acclaimed Apple TV series based on the trilogy by novelist Hugh Howey, which hinted at a mysterious origin story dating back centuries. Apple TV just released the full trailer, and it looks like our heroine is again facing conflict and danger because she just keeps asking so many inconvenient questions.

As previously reported, Silo is set in a self-sustaining underground city inhabited by a community whose recorded history dates back only 140 years. The outside is a toxic hellscape that is only visible on big screens in the silo’s topmost level. The second season expanded Silo‘s world to incorporate the survivors in the second Silo 17; everyone else died in a revolt to escape to the surface. We discovered that there are 50 silos in all. Meanwhile, another revolution was brewing in Juliette’s (Rebecca Ferguson) original Silo 18 against Holland (Tim Robbins). And even more secrets were revealed.

In the season finale, Juliette returned to her silo and warned the residents not to leave, but she and Holland ended up locked in the incinerator just as it was being fired up. The final scene was a flashback, showing a woman questioning a congressman in Washington, DC, about possible retaliation after the US dropped a dirty bomb on Iran. And that brings us to S3. Per the official premise:

Blue Origin has set a very aggressive return-to-flight timeline

Blue Origin has set a very aggressive return-to-flight timeline

fivenewscrypto    juin 03, 2026   

The chief executive of Blue Origin, whose large New Glenn rocket exploded spectacularly less than a week ago at the company's launch site in Florida, vowed Monday night that the company would launch again before the end of 2026.

Writing on the social media site X, Blue Origin's Dave Limp said the company had been able to complete a preliminary survey of the LC-36A launch site.

"Now that we’ve had access to the pad and integration facility, we can share a bit of good news," Limp said. "The propellant farm, oxygen, liquid hydrogen and LNG tanks are all in good shape. This is good luck because these are very long lead items. The water tower is also good."

Trump's DOE restarts energy rebate program with dumb conditions

Trump's DOE restarts energy rebate program with dumb conditions

fivenewscrypto    juin 03, 2026   

Federal energy efficiency rebate programs will no longer cover a switch from fossil fuels to electricity for heating, according to long-awaited guidance from the Department of Energy.

The department published an update on how it will implement consumer programs with $8.8 billion in funding. The new provisions include eliminating use of diversity, equity and inclusion considerations, among other changes.

This follows legal challenges after President Donald Trump issued an executive order last year, upon returning to office, canceling the release of funds from Biden’s Inflation Reduction Act, including rebates for home energy efficiency. A coalition of states successfully sued to restore the funding, obtaining an injunction in March 2025.
