Tarsnap is cozy

I have been aware of tarsnap for a long time, but only recently did I actually get around to using it for anything, as a result of my big personal digital resiliency audit for 2025. For those of you not in the know, tarsnap is “online backups for the truly paranoid”, and tarsnap the command-line program is the client-side tool you invoke to actually zip up and push your archives into the vault. Its creator, Dr. Colin Percival, is a really smart and interesting dude for a whole bunch of reasons.

NASA Found Signs of Ancient Alien Life on Mars. Here's How Excited You Should Be

NASA released a significant update from the Perseverance Mars rover on Wednesday, focusing on a particularly juicy tidbit for those watching from home: A small rock sample called Sapphire Canyon showed signs of potential biosignatures, or ancient alien life that may have once grown on Mars. That's possible because of the unique location where Perseverance located the sample in July 2024. It came from a rock named Cheyava Falls. This particular rock is in Jezero Crater, home to an ancient dry ri

NASA Says Its Mars Rover Has Detected Possible Signs of Life on the Red Planet

NASA has announced that its Perseverance Mars rover spotted "potential biosignatures" in an ancient dry riverbed last year. Samples collected from a rock dubbed "Cheyava Falls" contain a structure that hints at the possibility of having a biological origin, according to the space agency, but more research needs to be completed to draw any conclusions about the presence of life on the Red Planet. "The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, an

Experimental Cream Could Make ‘Permanent’ Scars a Thing of the Past

Cool guys may have scars, but plenty of people would relish the opportunity to get rid of their own. In new research out this week, an experimental drug has shown promise at being able to clear up lingering scar tissue. Scientists in Australia conducted the study, a phase I trial of a tropical cream developed by the company Syntara. People applying the cream experienced no major side effects, they found, and the drug appeared to trigger changes in the skin within older, or mature, scars. Though

SpaceX Targets an Orbital Starship Flight with a Next-Gen Vehicle in 2026

It has been two weeks since SpaceX’s last Starship test flight, and engineers have diagnosed issues with its heat shield, identified improvements, and developed a preliminary plan for the next time the ship heads into space. Bill Gerstenmaier, a SpaceX executive in charge of build and flight reliability, presented the findings Monday at the American Astronautical Society’s Glenn Space Technology Symposium in Cleveland. The rocket lifted off on August 26 from SpaceX’s launch pad in Starbase, Te

NASA's Perseverance rover finds potential signs of ancient life on Mars

NASA just announced that its Perseverance rover recently found some promising signs of ancient life on Mars. The rover obtained a sample of rock formed billions of years ago from sediment and there are biomarkers indicating the potential presence of microbes once upon a time. Basically, the rocks contain minerals that typically form as a result of a chemical reaction between mud and organic matter. That doesn't necessarily mean that Mars once had life, as the minerals can form due to nonbiologi

Starship to Deliver 100 Tons to Orbit by 2026, Musk Claims

Starship finally broke a losing streak of back-to-back flops, acing its 10th suborbital flight last month. Following the rocket’s success, SpaceX founder and CEO Elon Musk is now confident that the massive vehicle will begin flying payloads to space in 2026. During an interview with the All-In Podcast, Musk explained how an upgraded version of Starship will reach orbit by next year and demonstrate full reusability of the Super Heavy booster and its upper stage. “Unless we have some very major s

Flush door handles are the car industry’s latest safety problem

Earlier this week, Ars spent some time driving the new Nissan Leaf. We have to wait until Friday to tell you how that car drives, but among the changes from the previous generation are door handles that retract flush with the bodywork, for the front doors at least. Car designers love them for not ruining the lines of the door with the necessities of real life, but is the benefit from drag reduction worth the safety risk? That question is in even sharper relief this morning. Bloomberg's Dana Hul

Pontevedra, Spain declares its entire urban area a "reduced traffic zone"

With the number of passenger vehicles rising across Europe, cities are grappling with air pollution, traffic accidents, and the loss of public space. In Spain, the city of Pontevedra has managed to overcome these challenges, surpassing national air quality standards and creating safer streets. The key, according to the Galician municipality’s mayor, is an urban model that prioritises residents over cars – without imposing an outright ban on private vehicles. It is a bright summer evening in Pon

Nova Launcher’s death is sad, but let’s face it — it’s been dead for a while

Andy Walker / Android Authority There’s no shortage of Android launchers for those seeking something beyond the default experience. I’ve tried many in my time, but one firmly stands out for Android enthusiasts: Nova Launcher. I used it for years, through various Android versions and on multiple smartphones.

Tesla Wants Out of the Car Business

Elon Musk still makes some of America’s best electric cars. Earlier this summer, I rented a brand-new, updated Tesla Model Y, the first refresh to the electric SUV since it debuted, in 2020. Compared with even just two years ago, when the Model Y became the world’s best-selling car, many companies make great EVs now. Some of them have the Model Y beat in certain areas, but for the price, the Tesla is still the total package. Now, imagine how good Teslas could be if Musk apparently wasn’t so bor

Cillian Murphy Is Flattered Everyone Thought He Would Play an Emaciated Zombie in ’28 Years Later’

As soon as the teaser trailer for 28 Years Later dropped, pretty much everyone and their mom assumed the skinny zombie seen struggling through flowers looked uncannily like Cillian Murphy’s Jim, the franchise’s original main character from director Danny Boyle and Alex Garland‘s 2002 28 Days Later. The internet sleuths swiftly discovered the likeness was pure serendipity, but the Oscar-winning actor now says he was touched that fans had assumed the emaciated undead wanderer was him.

How Britain built some of the world’s safest roads

How Britain built some of the world’s safest roads The death rate per mile driven has declined 22-fold since 1950. A century ago, these were the cars on Britain’s roads. Forget driving lessons or tests; to get behind the wheel legally, all you needed was a paper license, which cost the equivalent of around 25 pence today. Cars had no seatbelts and, of course, no airbags. There were no mirrors to let you see traffic behind. There were no flashing indicators, so your signal to turn left or right

How to make metals from Martian dirt

27 August 2025 3 min read Key points Swinburne and CSIRO researchers are investigating ways to produce native metals using materials found on Mars. Martian settlements will require large amounts of metal that are difficult to ship from Earth. The team have successfully produced iron using regolith simulant that mimics what is available on the Red Planet. The idea of building settlements on Mars is a popular goal of billionaires, space agencies and interplanetary enthusiasts. But constructio

A New Graphic Novel Will Chronicle How ‘Star Wars’ Got Made

For anyone who wants to read about the history of the original Star Wars, a new graphic novel is coming. That would be Lucas Wars, the newly translated version of a story originally published in 2023 by French journalist Laurent Hopman and illustrator Renaud Roche. The graphic novel tells of George Lucas’ decade-long journey to get the classic sci-fi film made, starting from him surviving a car accident to his journey through film school and clashes with 20th Century Fox. In an email to the Hol

The Robot Vacuum’s Next Humble Trick: Climbing Stairs

Stair-climbing robot vacuums are actually about to be a reality, sort of. That’s courtesy of a little baby trend at IFA 2025 of robot vacuums slipping into something more climbable—a little caddy that carries them upstairs when it’s time to move floors, then waits to carry them back down when they’re done. The first one we encountered was the Eufy MarsWalker. Then, it turned out that Dreame had one, too, using almost the exact same approach, only it’s weirdly much scarier-looking. Both have a s

Scientists Intrigued by Non-Human Skull Embedded in Cave Wall

Scientists believe they're close to solving an ancient mystery involving a strange hominin skull, neither Neanderthal nor human, that was found fused to a cave wall — with a stalagmite sticking out of the top, to complete the eerie scene — in Macedonia, Greece. In a new study published in the Journal of Human Evolution, researchers from France's Institut de Paléontologie Humaine (or Human Paleontology Institute in English) claim they've been able to place an age on the "Petralona cranium," whic

New Study Upends Origin Theory of Mysterious Interstellar Object

Ever since interstellar object 3I/ATLAS streaked into our solar system, astronomers have been scrambling to understand how this likely comet got here—and more importantly, perhaps, where it came from. As only the third interstellar object ever discovered, 3I/ATLAS offers a rare chance to study remnants of solar systems beyond our own, briefly bringing the distant galaxy within reach. But before we get into the new study, imagine the Milky Way as a kind of celestial sandwich: Inside is a thin d
