Astronomers Revisit the Mysterious Wow! Signal—and Find a Big Surprise

Nearly 50 years ago, astronomers searching the cosmos for evidence of intelligent extraterrestrial life detected a strong radio signal emanating from deep space. Today, scientists still aren’t sure where—or what—the Wow! Signal came from. It remains one of the most perplexing phenomena in the history of radio astronomy. A new study has brought scientists closer than ever to solving that mystery. Researchers from the Arecibo Wow! (AWOW) project at the Arecibo Observatory in Puerto Rico recently

Bitcoin Flash Crash Roils Crypto Market

Crypto prices dipped Monday following a so-called flash crash of Bitcoin on Sunday. And while Ethereum dipped as well, the second most popular cryptocurrency is still up significantly on the month. Bitcoin’s weekend crash is being blamed on a single whale who sold 24,000 Bitcoin, according to crypto watchers on X. Bitcoin’s most recent peak hit $117,370 on Friday, not too far from the all-time high of $124,500. But Bitcoin is currently sitting at $112,660, well below recent highs. “Bitcoin fla

Best Eye Doctor-Approved Over-the-Counter Eye Drops of 2025

Depending on how often you plan to use the eye drops and what you're using them for, a preservative-free brand may be best. Also, some preservatives are safer than others. Make sure to look at the active ingredients in your eye drops -- some chemicals can cause issues in the eyes over time. Eye drops may be designed to treat dryness, redness or other eye issues. Some conditions require prescription eye drops instead of over-the-counter ones. CNET staff -- not advertisers, partners or business

Study shows which vehicles pollute the least in every US county

Greenhouse gas reduction is no longer a priority for the US government, but if you're looking for a new vehicle and want to buy something with the lowest life cycle carbon emissions, you're best off looking for a compact with a small battery. That's one of the findings of a comprehensive study from a group at the University of Michigan that calculates the overall cradle-to-grave carbon impact for different types of vehicles, including factors like powertrain options, location (within the country

The unlikely revival of nuclear batteries

In 1970, surgeons in Paris implanted the first nuclear-powered pacemaker, and over the next five years, at least 1,400 additional people received the devices, mostly in France and the United States. Encased in titanium, the batteries for these devices contained a radioactive isotope—typically about a tenth of a gram of plutonium-238—and could operate for decades without maintenance. The invention provided relief to a population of people who previously needed surgery every few years to change ou

FTC warns tech giants not to bow to foreign pressure on encryption

My favorite iOS 26 feature is something Android has had for years

Ryan Haines / Android Authority The year is 2015. You plug your Android phone in to charge, and a helpful little timer tells you how long it should take. You pop on an episode of Narcos. Life is good. Your friend with an iPhone? Yeah, they plug in their phone too, waiting to fill their tiny, well-optimized cell. The difference? They have no idea how long it’ll take. Fast-forward to early 2025. You plug in your Pixel 9a and limit its charging to 80% of capacity to preserve battery health. Your

Changing these 6 settings on my iPad greatly extended its battery life by hours

Prakhar Khanna/ZDNET As an avid iPad user, I'm all too familiar with the internal struggles that course through me when the battery is about to die. I love using either the iPad 11 or iPad Air to write and work, but I also use it to stream content, play games, and browse the internet after work. This makes me appreciate the iPad's long battery life, yet my anxiety grows when I start getting 'low battery' alerts without a charger nearby.

IBM and NASA Develop a Digital Twin of the Sun to Predict Future Solar Storms

The Sun’s most complex mysteries could soon be solved thanks to artificial intelligence. On August 20, IBM and NASA announced the launch of Surya, a foundation model for the sun. Having been trained on large datasets of solar activity, this AI tool aims to deepen humanity’s understanding of solar weather and accurately predict solar flares—bursts of electromagnetic radiation emitted by our star that threaten both astronauts in orbit and communications infrastructure on Earth. Surya was trained

In-Memory Filesystems in Rust

In-memory Filesystems in Rust I’ve been working on a CLI tool recently, and one of the things it does is manage files on disk. I have written a lot of file management tests for Bundler, and the two biggest reasons that the Bundler test suite is slow are exec and fstat . Knowing that, I thought I would try to get out ahead of the slow file stat problem by using an in-memory filesystem for testing. A collaborator mentioned being happy with the Go package named Afero for this purpose, and so I se

Ether rises to a fresh record, bitcoin erases gains from Jackson Hole rally

Ether rose to a new record over the weekend, after hitting an all-time high Friday for the first time since 2021. The price of the second largest cryptocurrency rose as high as $4,954.81 on Sunday afternoon. It was last higher by less than 1% at $4,776.46. Meanwhile, bitcoin at one point erased all the gains from its Friday rally, falling as low as $110,779.01, its lowest level since July 10. It was last trading lower by nearly 2% at about $112,000. The flagship cryptocurrency hit its most rec

You’ll Squint and Wipe Your Glasses When You See This Leaked Data on How Much Microsoft Engineers Are Getting Paid

One of the more salient side effects of the incredible shrinking tech sector is the loss of so many high-paying jobs, many of which young jobseekers were encouraged to apply for by those who implored them to "learn to code." As such, we generally expect inflated salaries when we learn what people who work at Big Tech firms make — between $120,000 and $160,000 for entry-level positions, say, and up to a half a million dollars for middle management. That's what makes it so weird when, upon looki

South Korean Man Arrested in $50 Million Crypto Scam

A South Korean man was arrested in Bangkok, Thailand on Saturday, accused of laundering over $50 million worth of cryptocurrency into physical gold bars in the span of just three months. The man, identified by Thai authorities only as “Han,” was allegedly a key figure in a call-center fraud network that lured victims in with promises of 30-50% returns on investment. Authorities say the victims were paid off initially in small amounts to build trust before they started facing withdrawal limits l

AGI is an engineering problem, not a model training problem

Published: Aug 13, 2025 | at 11:00 AM We’ve reached an inflection point in AI development. The scaling laws that once promised ever-more-capable models are showing diminishing returns. GPT-5, Claude, and Gemini represent remarkable achievements, but they’re hitting asymptotes that brute-force scaling can’t solve. The path to artificial general intelligence isn’t through training ever-larger language models—it’s through building engineered systems that combine models, memory, context, and determ

How can AI ID a cat?

Look at a picture of a cat, and you’ll instantly recognize it as a cat. But try to program a computer to recognize cat photos, and you’ll quickly realize that it’s far from straightforward. You’d need to write code to pinpoint the quintessential quality shared by countless cats in photos with distinctive backgrounds and taken from different camera angles. Where would you even begin? These days, computers can easily recognize photos of cats, but that’s not because a clever programmer discovered

Scientists Alarmed to Discover That Earth's Continents Are Drying Out

New research examining over 20 years of data captured by NASA's twin climate satellites, GRACE and GRACE-FO, has revealed an "unprecedented" level of water loss among the planet's continents, creating "mega-drying" regions across the northern hemisphere. One of these mega regions spans Europe, the Middle East, North Africa, and vast swaths of Asia. That should clue you in to the staggering scale of this phenomenon, which the scientists are calling terrestrial water storage (TWS) loss. Since 200
