Best Wi-Fi Extenders of 2025

Editor's Note: We think you should be aware that TP-Link routers are under investigation by the US government over security concerns and could be banned in the US this year, according to multiple news reports. The TP-Link Archer RE605X was previously named our best overall choice for Wi-Fi extenders. While our evaluation of the hardware hasn't changed, out of extreme caution for our readers, we decided to pause it as our top recommendation until we learn more. Read CNET's reporting for more info

Is Gravity Just Entropy Rising? Long-Shot Idea Gets Another Look

Isaac Newton was never entirely happy with his law of universal gravitation. For decades after publishing it in 1687, he sought to understand how, exactly, two objects were able to pull on each other from afar. He and others came up with several mechanical models, in which gravity was not a pull, but a push. For example, space might be filled with unseen particles that bombard the objects on all sides. The object on the left absorbs the particles coming from the left, the one on the right absorb

Lisp-stat: Lisp environment for statistical computing

Lisp-Stat is conceptually similar to R and will be familiar to most people from that ecosystem. It is suitable for both exploratory data analysis as well as front-line production deployments. Common Lisp is currently used at Google in several high-availability, high-volume transactional systems. Why Lisp? We had a few requirements when evaluating options. Specifically the system had to: Work well in the kind of exploratory environment conducive to analytics and AI Be robust enough to work in

Stanford Doctors Invent Device That Appears to Be Able to Save Tons of Stroke Patients Before They Die

Image by Andrew Brodhead Researchers have developed a novel device that literally spins away the clots that block blood flow to the brain and cause strokes. As Stanford explains in a blurb, the novel milli-spinner device may be able to save the lives of patients who experience "ischemic stroke" from brain stem clotting. Traditional clot removal, a process known as thrombectomy, generally uses a catheter that either vacuums up the blood blockage or uses a wire mesh to ensnare it — a procedure

David Attenborough at 99: 'I will not see how the story ends'

My earliest memory of the ocean is of a tropical lagoon. Ammonites rose and fell in the warm water column, occasionally propelling themselves forwards, their curled ram’s horn shells surprisingly streamlined in the water. This tropical lagoon was in fact in my imagination, fired as I explored the old limestone quarry near my childhood home in Leicester, some 60 miles from the coast. For a small boy in the 1930s this was a marvellous place for adventures, and the knowledge that millions of year

ChatGPT Search gets an upgrade as OpenAI takes aim at Google

On June 13, OpenAI began rolling out a new ChatGPT Search update to improve quality as the AI startup challenges Google’s dominance.

Bits and bobs related to Wireless-Tag's WT32-ETH01 board

Unofficial guide to the WT32-ETH01 What is this thing and why would I use it? The WT32-ETH01 is effectively a small, cheap ESP32 development board with Ethernet, WiFi, and GPIO pins, made by a company called "Wireless-Tag" (WT). As of this writing, it's around $15 at JacobsParts and around $7 from AliExpress. There aren't a ton of ESP32 boards with Ethernet, and the WT32-ETH01 is by far the smallest, cheapest, and simplest. (The OLIMEX ESP32-POE and wESP32 are the other notable options.) So,

The Art of Lisp and Writing (2003)

The Art of Lisp & Writing Ignorance more frequently begets confidence than does knowledge. –Charles Darwin Lisp is the language of loveliness. With it a great programmer can make a beautiful, operating thing, a thing organically created and formed through the interaction of a programmer/artist and a medium of expression that happens to execute on a computer.

What Is Raspberry Pi and How Can I Use It for My Home Internet?

A Raspberry Pi computer can do a little of everything, including keeping you occupied if you need a new project (or distraction). This teeny-tiny computer not only clocks in at a low price, but could potentially help you trim costs by becoming a DIY router. Saving money is appealing: A recent CNET survey showed that internet costs spiked for 63% of US adults last year. When our budgets are tight, having a device that can cover the gamut is appealing, from hosting your home internet to providing

Companies may soon pay a fee for their rockets to share the skies with airplanes

The Federal Aviation Administration may soon levy fees on companies seeking launch and reentry licenses, a new tack in the push to give the agency the resources it needs to keep up with the rapidly growing commercial space industry. The text of a budget reconciliation bill released by Sen. Ted Cruz (R-Texas) last week calls for the FAA's Office of Commercial Space Transportation, known as AST, to begin charging licensing fees to space companies next year. The fees would phase in over eight year

The Mysterious Inner Workings of Io, Jupiter’s Volcanic Moon

The original version of this story appeared in Quanta Magazine. Scott Bolton’s first encounter with Io took place in the summer of 1980, right after he graduated from college and started a job at NASA. The Voyager 1 spacecraft had flown past this moon of Jupiter, catching the first glimpse of active volcanism on a world other than Earth. Umbrella-shaped outbursts of magmatic matter rocketed into space from all over Io’s surface. “They looked amazingly beautiful,” said Bolton, who is now based a

Alexa von Tobel has high hopes for ‘fintech 3.0’

It’s been 10 years since Alexa von Tobel sold her financial planning startup Learnvest to Northwestern Mutual for $250 million.

Scientists Reveal Easy Three-Step Plan to Terraform Mars

Terraforming, the act of radically transforming a planet's climate and environment to make it suitable for human habitation, currently belongs to the realm of science-fiction. But it's possible, at least in theory, and the idea of terraforming our nearest candidate planet for off-world colonization, Mars, has captivated us for generations. But how would we even begin to pull off such a monumental feat of engineering? You can basically boil it down to three simple steps, argue the authors of a r

The Space Station Leak Is Rearing Its Ugly Head Again

Answering the Nintendo Switch 2’s lingering accessibility questions

One of the biggest surprises of the Nintendo Switch 2’s reveal was its proposed accessibility.

This was supported by a webpage dedicated to the Switch 2’s hardware accessibility. However, specifics were thin and no furth
