After noise complaints, judge orders Waymo to stop overnight charging in Santa Monica

fivenewscrypto    août 03, 2026   

A local judge has ruled that Waymo can no longer use its side-by-side charging facilities overnight in Santa Monica, California, as these may pose a “public nuisance.”

Los Angeles Superior Court Judge Bradley S. Phillips granted this week the City of Santa Monica’s motion for a preliminary injunction in the city’s ongoing public nuisance lawsuit against the autonomous vehicle giant.

City officials and neighbors assert that the constant stream of vehicles at the charging stations create light and sound pollution and cause undue traffic congestion on the streets and nearby alleys, creating a collective bother and disruption.

Defcon's new badge is a security key you can see inside

Defcon's new badge is a security key you can see inside

fivenewscrypto    août 03, 2026   

It’s been a longtime feature of the annual Defcon hacker conference that attendees come away not only with knowledge of new software vulnerabilities and hacking techniques but also an elaborately designed conference badge—often electronic masterpieces embedded with intricate puzzles, complex crypto challenges, hidden Easter eggs, and even the mechanical gear trains of a watch.

Each year’s badge creator endeavors to top previous designs and blow the minds of hard-to-impress hackers. But this year’s badges take a different tack. Instead of the badge designs being the star, it’s what is inside the hardware that will really stand out.

This year, Defcon asked legendary hardware hacker Andrew “bunnie” Huang to create the badges—revealed here for the first time—and they include an innovative open source chip that Huang designed and that aims to do no less than advance the state of security, transparency, and trustworthiness in computing.

How fruit flies chase invisible ribbons of smell to get to their source

How fruit flies chase invisible ribbons of smell to get to their source

fivenewscrypto    août 03, 2026   

A fruit fly hunting a piece of rotting fruit or a mate navigates by smell, following plumes of odor. Out in the wild, turbulent air swirls these plumes into a chaotic, broken landscape—dense chemical filaments laced through long stretches of clean air. A fly trying to find the source gets the smell in stutters, from constantly shifting directions, with no guarantee that a next whiff is coming at all.

Scientist had little idea of how fruit flies manage this chaotic signal with a brain the size of a pinhead. For a long time, biologists stood by the “surge and cast” model, which posited that insects solved this with hardwired reflexes. The idea was that, when a fly registers the plume with olfactory neurons in its antennae, it simply flies upwind until it’s gone and then flies side to side attempting to catch it again. But now a team led by Vanessa Ruta, a neuroscientist at the Rockefeller University, has shown that fruit flies do something far more advanced.

A treadmill for flies

The trouble with the traditional surge and cast model is that it struggles to explain how an insect tracks a meandering plume across long distances. Chemical cues floating in the air in the natural environment are often sparse and unreliable. But those same features make the mechanism behind olfactory navigation notoriously difficult to test. "Odors are invisible," Ruta says, "and often they're carried along by turbulent airflow." We’ve got no way of knowing what the animal is smelling from one moment to the next.

Not just Neanderthals: Ghost lineage in Africa left its mark on our DNA

Not just Neanderthals: Ghost lineage in Africa left its mark on our DNA

fivenewscrypto    août 03, 2026   

When the history of our ancestry is written, the fact that we've interbred with some of our closest relatives, the Neanderthals and Denisovans, will have a central role. And it will be tempting to write it as a very tidy story: Once we got genomes from these other groups, it was possible to identify the sequences in our genomes that we shared with them.

But in reality, as scientists started poking large enough collections of data, there were regular hints of some strange ancestry in our genomes. It was hard to pin down, though, at least in part because the 2 percent on average of Neanderthal DNA found in many populations does not guarantee that any two individuals will have the same 2 percent. So having the genomes of those two groups made sense of some things researchers had already been seeing.

But knowing what we do about Neanderthal and Denisovan DNA is now allowing researchers to answer a somewhat different question: Is there anything else? Using recently developed analytical techniques, they find evidence of a third lineage that we apparently interbred with before any modern humans left Africa. Again, there were hints of this earlier, but so far, there's been no genome from a modern human relative to help us understand the details—the source of this DNA remains a "ghost lineage."

Doctors took a look at man's painful shoulder—they found the joint was missing

Doctors took a look at man's painful shoulder—they found the joint was missing

fivenewscrypto    août 02, 2026   

A 45-year-old construction worker went to the emergency department for his right shoulder, which was extremely swollen and becoming progressively more painful. Doctors took an X-ray to try to see what was causing the problem. But when the images came through, it was what they didn't see that explained the situation: His entire shoulder joint was gone, seemingly blasted apart into small, lingering pieces.

The shoulder joint is a ball-and-socket joint, with the sphere-like head of the upper arm bone (humerus) sitting in the socket of the shoulder blade. According to a case report in the New England Journal of Medicine, the man's X-ray showed that he no longer had a ball at all or an intact socket. His upper arm bone was detached from the joint, and the sphere-like top of his upper arm bone (humeral head) was completely gone. The broken, headless humerus was instead left to float freely in the man's arm, unattached to his upper body.

Magnetic resonance imaging, meanwhile, found that the man's rotator cuff—the group of muscles and tendons that holds the upper arm firmly in the socket—was also destroyed. Three of the four main tendons (supraspinatus, infraspinatus, and subscapularis tendons) had full-thickness tears.

Google plans to exempt sanctioned nations from Android developer verification

Google plans to exempt sanctioned nations from Android developer verification

fivenewscrypto    août 02, 2026   

We are a month away from the initial rollout of Google's Android developer verification system, and the company contends this policy does not impinge on the platform's open nature. Still, the restrictions will be a big change, and there are still some unanswered questions. An issue that has come up repeatedly in the run-up to verification is what will happen to devs who can't verify because of where they live. It turns out that Google has a cryptic answer for that buried in an FAQ.

Developer verification will soon block the installation of apps from unverified developers on any Android device running Google services, which is functionally all Android phones outside Russia and China. Developers who want to keep releasing software, even if it's not in the Play Store, have to provide Google with their ID and pay a small fee.

But what if you're an Android developer living in a sanctioned nation? Currently, the US sanction list includes Iran, Cuba, North Korea, and occupied areas of Ukraine. Given the current uncertain state of US foreign policy, that list could change in the future. Google doing any business with developers in those places is a thorny issue, and it seems like the company has decided to just leave them hanging.

Reddit keeps its strange DMCA fight over Google search results alive

Reddit keeps its strange DMCA fight over Google search results alive

fivenewscrypto    août 02, 2026   

On Friday, a judge largely denied a motion to dismiss from a web scraper, SerpApi, which is accused of conspiring with Perplexity AI to illegally scrape copyrighted Reddit content from Google search results.

In his opinion, US District Judge Paul A. Engelmayer said that at this early stage, Reddit has plausibly pleaded that there was a conspiracy, with SerpApi providing a product to circumvent Google access controls and Perplexity AI paying for it.

Engelmayer’s decision came less than two weeks after another court dismissed a similar action raised by Google, finding that the company had not proven that rights holders, such as Reddit, had ever authorized the search engine to prevent the scraping of protected content. Google told Ars that it planned to amend its complaint to keep its lawsuit alive, but SerpApi told Ars that Google and Reddit were both trying to “use the DMCA to wall off the open Internet by retroactively claiming control over content that they didn’t author and don’t own.”
