9 Best Natural Deodorants, Tested and Reviewed (2025)

These Deodorants Are Just OK Photograph: Louryn Strampe Kopari Performance Plus Deodorant for $20: This deodorant smells great—like a floral, beachy coconut. It’s more fresh than sweet, and I’d say it’s unisex-leaning-feminine. It goes on clear and smooth, and it didn’t stain my clothes at all. However, it didn’t last me through a workout without reapplying, unlike some other brands I tried. I think it’s fine, but I wouldn’t call it a “performance deodorant.” If you’re looking for a clear form

An epic year for women’s sports

In March, the indoor track and field team scored 49 points—the most ever by an MIT women’s team at a n

Breaking WebAuthn, FIDO2, and Forging Passkeys

Okay, but why does this even work? Forging Passkeys: Exploring the FIDO2 / WebAuthn Attack Surface Fri Jun 20 2025 authored by vmfunc Introduction Passwords are dying—slowly, awkwardly, and not without a fight. Large parts of the internet are already nudging users toward "passkeys", the marketing-friendly name for FIDO2 credentials that live on your phone, security key, or TPM. In theory passkeys solve phishing and credential-stuffing in one swoop. In practice... they might introduce a shin

UK may require Google to give users alternative search options and rank its results ‘more fairly’

The U.K.’s competition regulator said on Tuesday it is considering a new market designation for Google that would require the search giant to provide alternative search options to users, rank search results “more fairly,” and offer greater control to publishers over how their content is used in search and AI Overviews.

Trump's Attack May Instead Spur Iran to Speedrun a Nuclear Weapon It Wasn't Building Previously

Trump's Attack May Instead Spur Iran to Speedrun a Nuclear Weapon It Wasn't Building Previously An extremely ironic outcome. Bomb Squad President Donald Trump is trying to derail Iran's nuclear weapons ambitions by bombing its known nuclear research facilities — but it turns out that's easier said than done. US officials have trumpeted that the recent strikes obliterated Iran's nuclear enrichment sites, but satellite images have cast doubt on that claim. And in any case, Trump's bombing camp

Still upset about last summer’s Spotify price bump? These lawmakers are on the case

Tech Team / Android Authority TL;DR Last year Spotify introduced audiobook access and raised pricing for Premium plans. While there was still a music-only Basic option, these senators don’t think consumers were made adequately aware. They also accuse Spotify of orchestrating the whole change to lower its payouts to musicians. Streaming services raising their prices is just as inevitable as death and taxes, and year after year, we slowly end up paying more and more for that access. While we m

Ted Cruz can’t get all Republicans to back his fight against state AI laws

A Republican proposal to penalize states that regulate artificial intelligence can move forward without requiring approval from 60 senators, the Senate parliamentarian decided on Saturday. But the moratorium on state AI laws did not have unanimous Republican support and has reportedly been watered down in an effort to push it toward passage. In early June, Sen. Ted Cruz (R-Texas) proposed enforcing a 10-year moratorium on AI regulation by making states ineligible for broadband funding if they t

​​How to Become a Backyard Naturalist With Just Your Smartphone

In the early days of summer, backyards come to life. Warmer temperatures transform spring buds into lush greenery, coax insects from their winter slumber, and invite newborn animals to explore their surroundings on wobbling legs or wings.

And while June is an especially good time to start, you can use your phone to obs

Nvidia wants in on the nuclear renaissance, invests in Bill Gates-backed TerraPower

TerraPower, the nuclear startup founded and backed by Bill Gates, announced a new $650 million funding round this week. The investment will help the company build its first commercial power plant. Like other nuclear startups, TerraPower has been riding a wave of interest from hyperscalers, data center developers, and, now, chip designers.

Oklo, the Earth's Two-billion-year-old only Known Natural Nuclear Reactor (2018)

Physicist Francis Perrin sat at a nuclearfuel-processing plant down in the south of France, thinking to himself: “This cannot be possible.” It was 1972. On the one hand, there was a dark piece of radioactive natural uranium ore, extracted from a mine in Africa. On the other, accepted scientific data about the constant ratio of radioactive uranium in ore. Examination of this high-grade ore from a mine in Gabon was found to contain a lower proportion of uranium-235 (U-235) — the fissile sort. Onl

Open source can't coordinate?

Open Source Can’t Coordinate I was taking a shower this morning, and was pondering yesterday’s problem, where I suspect that I have an outdated version of hotspot Linux profiler, but I can’t just go and download a fresh release from GitHub, because hotspot is a KDE app, and I use NixOS. And NixOS isn’t a problem — it’s a solution. Linux on desktop is a rickety tower of competing libraries, protocols and standards, which is always in an Escheresque sort of perpetual motion, taking off but simul

2025 Audi S5 and A5 first drive: Five-door is the new four-door

Audi provided flights from Washignton, DC, to Denver and accommodation so Ars could drive the A5 and S5, as well as the Q5 and SQ5. Ars does not accept paid editorial content. ASPEN, Colo.—The SUV might be the dominant design in the American automobile market, but it hasn't completely taken over. At Audi, there is still life in the sedan. The old A4 four-door is no more—at least for a while or until Audi redoes its nomenclature yet again. If you want a small Audi four-door, you need to step dow

JetBlue Is Slashing Flights and Cutting Costs. Here's What Travelers Should Know

JetBlue is tightening its belt: The airline on Tuesday announced a round of cost-cutting measures, including fewer routes and reduced spending. JetBlue says it's scaling back its flight schedule and reducing services to several US states and major metropolitan airports, such as John F. Kennedy International Airport. That means fewer options for travelers in and out of cities where the airline had been aggressively expanding, such as New York, Boston and Fort Lauderdale. The company is also trim
