The Army just used a 20-kilowatt laser to take out three drones

This week, the US Army used a high-energy multipurpose laser to shoot down three drones near the US-Mexico border, which official reports claimed were “posing a physical threat to US military personnel and CBP partners,” referring to Customs and Border Patrol.

The operation took place between the night of August 25 and the early morning of August 26 in the vicinity of the Rio Grande Valley in Texas and was led by the Joint Task Force Southern Border (JTF-SB), which operates under US Northern Command. Authorities confirmed that, during the operation, agents used technology derived from the Army’s High-Energy Multipurpose Laser (AMP-HEL) system, a military program focused on implementing high-energy lasers for new defense capabilities.

Available information suggests that this initiative began in September 2025, when AeroVironment, a company specializing in defense technology, delivered the first two functional prototypes of these laser-based weapons to the US Armed Forces. Two new, improved systems were delivered as the program was expanded in December of the same year. According to the manufacturer, this particular platform, called the Locust Laser Weapon System, is designed to be mounted on military vehicles, as the Army has done with the versions it has received.

Is Russia's rival to Starlink failing? Here's what we know.

Is Russia's rival to Starlink failing? Here's what we know.

fivenewscrypto    septembre 03, 2026   

Russia's attempt to replicate SpaceX's Starlink satellite network seems to be moving as slowly as the front lines in eastern Ukraine.

The Rassvet program, often billed as Russia's answer to Starlink, started launching its first operational satellites earlier this year. Two launches, one in March and a second in July, have delivered 32 Rassvet satellites to low-Earth orbit, some 10 percent of the roughly 300 Rassvet spacecraft Russia aims to put into orbit by the end of next year to provide connectivity for military and civilian users. The company in charge of Rassvet, Bureau 1440, wants to deploy 924 satellites by 2035.

But none of the 32 satellites launched so far have reached the 500-mile (800-kilometer) orbit they were designed to operate in. The rockets that launched the first two batches of Rassvets released the satellites much closer to Earth, and the satellites were expected to use their own plasma engines to raise their orbits over the next few months.

Research roundup: 7 cool science stories we almost missed

Research roundup: 7 cool science stories we almost missed

fivenewscrypto    septembre 03, 2026   

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. August’s list includes the discovery of a new celestial object astronomers have dubbed a "black hole star"; breaking down plastics with microbes and turning them into edible cookies; how whale calls are connected to Einstein's special theory of relativity; and how avocado tree flowers switch sex during the day, among other highlights.

Discovery of a "black hole star"

In 2024, astronomers combing through datasets taken by the James Webb Space Telescope noticed hundreds of mysterious little red dots lurking therein, believed to be baby quasars. They existed when the Universe was just a few hundred million years old. One such object in particular captured scientists' interest: a red dot that was extremely red and very bright, but whose properties didn't fit with any known astrophysical object. Astronomers have now concluded that the little red dot is a "black hole star," so named because it is the size of a large star but produces far more energy than would be possible via nuclear fusion—energy comparable to what an active black hole would produce.

A newborn and child reportedly died of measles; CDC isn't counting them

A newborn and child reportedly died of measles; CDC isn't counting them

fivenewscrypto    septembre 03, 2026   

The Centers for Disease Control and Prevention is excluding two measles deaths reported by Pennsylvania health officials last week from its latest update of national measles data. The move publicly challenges the accuracy of the state's death determinations in an extraordinary move that breaks precedent that states are the arbiters of case and death determinations, not the CDC.

The New York Times reported Monday that the CDC's new director, Erica Schwartz, is behind the decision. Schwartz—less than a month into the job—reportedly ordered CDC staff to add an unusual statement onto the CDC's website for measles surveillance data. The statement notes that the update will not include the deaths reported by Pennsylvania and continues: "At this time, available information does not establish whether measles caused or contributed to the deaths or whether the individuals died from other causes while infected with measles."

The Washington Post reported Monday that the CDC had actually changed the information provided on that page multiple times over the weekend. On August 29 at 2:33 pm ET, the website listed the total measles deaths for 2026 as "0" in a chart. On August 30 at 12:09 pm ET, the chart was updated to list the total deaths for 2026 as "2." There was also a note underneath the chart that read: "Health departments make determinations about measles-associated deaths and share relevant information with CDC." By 3:23 pm ET on August 30, the chart was changed again to delete the two deaths, replacing them with an asterisk as a reference to the unusual statement about the deaths not being included. The asterisk and statement remain as of Tuesday.

New Android Drop adds remembered items in Find Hub, makes anti-nausea dots official

New Android Drop adds remembered items in Find Hub, makes anti-nausea dots official

fivenewscrypto    septembre 03, 2026   

Let's be frank: Some of Google's recent Android feature Drops have been duds, offering little more than an expansion of Gemini summaries and chat functions. The new September Drop does have some Gemini flavor, but there are non-AI goodies, too. Your messaging threads are getting prettier and more useful, and those nifty Motion Assist dots that began appearing last week are rolling out widely. And even the Gemini expansion is not without utility.

Since this is an Android Drop rather than a Pixel Drop, these features are coming to a wider range of devices. The OS version does matter, though. If you're on Android 16 or higher, you can now tell Gemini to log the location of items that don't have a tracker tag attached. Just tell the AI where you put something, and include a photo if you like.

Remembered items in Find Hub

This information will be logged in Find Hub, which has thus far been used for locating phones, earbuds, and tracker tags. You can ask Gemini to recall that information or simply check Find Hub yourself the next time you forget where you put that item.

FTC alleges Amazon illegally made $20 billion by rigging billions of ad auctions

FTC alleges Amazon illegally made $20 billion by rigging billions of ad auctions

fivenewscrypto    septembre 03, 2026   

The Federal Trade Commission and 22 states sued Amazon yesterday, alleging that it has conducted a secret scheme to overcharge advertisers for seven years.

"Since 2019, Amazon.com, Inc. has secretly and systematically overcharged its approximately 1.2 million advertising customers by manipulating the 'auctions' that it uses to set the price of ads on its platform," the lawsuit said. "Amazon represents, and advertisers believe, that competitive auctions set the prices for advertising on its leading e-commerce website. But, in reality, Amazon overrides and replaces the actual auction results with higher prices set by Amazon to increase its profits."

The FTC said it obtained internal documents and messages that reveal how Amazon secretly inflated auction prices for Sponsored Products, Sponsored Brands, and Sponsored Display advertisements that appear alongside results seen by consumers when they search for a product. The FTC investigation began in 2024.

This is what a supercar was like a century ago

This is what a supercar was like a century ago

fivenewscrypto    septembre 02, 2026   

Bentley provided flights from Washington, DC, to Monterey, California, and accommodation so Ars could drive the new Supersports and ride in a preproduction Torcal EV, which we wrote about last week. While we were there, we went for a ride in something quite old. Ars does not accept paid editorial content.

MONTEREY, Calif.—Elsewhere on these pages, you can find our first track drive of the new Bentley Supersports. Shorn of its hybrid system and stripped back to rear-wheel drive, it's not only the most driver-focused Bentley we can remember, but it's also apparently the lightest car the company has made in 85 years. But you have to go back even further into the Bentley archive to find the first car to wear the Super Sports badge. And since Bentley had done just that, bringing along to Laguna Seca an example from the time, it would have been rude to refuse the offer of a ride.

Bentley built 18 Super Sports between 1925 and 1927, taking its standard 3 Litre model and shortening the wheelbase by 9.5 inches (241 mm). Like today's Super Sports, that shaved some mass and made it a more responsive driver's car. But a fast one, too. The radiator was more tapered and thus presented less resistance against the flow of air, although like many cars at the time, the bodywork was a matter of whichever coachbuilder the owner decided upon.

Smoky's two-seat bodywork was compact for the time.

Like today with the Continental GT and the new Supersports, the 3.0 L engine Bentley in the original Super Sports was more special than one you'd find in the standard car, with new pistons, a lighter flywheel, more compression, and different carburetors. Together with its unique gearing, the factory would guarantee a Super Sports that could exceed 100 mph (160 km/h); the millions of Ford Model Ts that took the roads those same years were hard-pushed to break 40 mph (64 km/h).
