Major reversal in ocean circulation detected in the Southern Ocean

Satellite data processing algorithms developed by ICM-CSIC have played a crucial role in detecting this significant shift in the Southern Hemisphere, which could accelerate the effects of climate change. Thanks to data obtained from Earth observation satellites, an international team of scientists has detected an unprecedented phenomenon for the first time: a reversal in the ocean circulation of the Southern Ocean. The study, led by the National Oceanographic Center (NOC, United Kingdom), was r

Google Now returns? Gemini Space could bring a Daily Hub feature to Pixels (Updated: Screenshot)

Ryan Haines / Android Authority TL;DR Google is developing a new feature called Gemini Space for Pixel devices, potentially as an evolution or rebrand of the current At a Glance feature.

Where is my von Braun wheel?

In 1962. There — that answers the clickbaity title right away. NASA had viable designs for rotating wheel space stations that could have given astronauts artificial gravity. Then, the Apollo program effectively killed them. While NASA’s lunar focus delivered the historic moonshot, it dismantled a promising engineering effort at Langley Research Center that might have revolutionized human spaceflight. That decision set us on a half-century trajectory of small, zero-gravity stations that continu

The Unseen Fury of Solar Storms

Credits Henry Wismayer is a writer based in London. I EXETER, United Kingdom — It was an overcast morning in southwest England, but Kirk Waite was staring at the sun. In the open-plan forecasting room of the Met Office, the U.K.’s national meteorological agency, the country’s senior weather-watchers were monitoring low-pressure systems sweeping in from the Atlantic and across the British Isles. Waite was studying weather of a very different sort. He sat at a crescent-shaped desk arrayed with

Nearly 500 Starlink Satellites Have Incinerated in Earth's Atmosphere So Far This Year

According to a filing with the Federal Communications Commission on Tuesday, 472 Starlink satellites burned up in the atmosphere between December 2024 and May 2025, as SpaceX deorbited around 6% of its active fleet. Starlink satellites are built to last around five years. After that, they're steered into the Earth's atmosphere to burn up. SpaceX, the rocket company owned by Tesla and X CEO Elon Musk, launched the first Starlink satellites in 2019, which means we're now seeing its first full-sca

You Can Still See the Aurora Borealis Tonight. Here's Where the Brightest Lights Will Glow

The Fourth of July holiday will bring explosive light shows on Friday night, but many folks will see much quieter and calmer lights in the sky tonight, as recent solar activity will continue to bring the Aurora Borealis to several US states. Wednesday night marks the winding down of a Kp 4 magnetic storm that the Space Weather Prediction Center reported starting late Monday evening. The K-Index measures the horizontal impact of geomagnetic storms, and a Kp4 or Kp 5 rating results in what the Na

Tinder Users Must Start Logging In With Their Faces

California Tinder users will find a new feature when they open up the dating app on July 7: A mandatory Face Check on their phones will be required before they can log into their profiles. The Face Check step will begin with a new request to record a video of your face, a more casual version of setting up Apple's Face ID login.

Here’s why you should probably steer clear of Samsung’s online-exclusive colors

Zac Kew-Denniss / Android Authority TL;DR Samsung reportedly requires authorized service centers to color-match replacement parts, including internal components. As a result, users with Samsung-exclusive colorways have faced unexpected repair delays due to limited part availability. This raises concerns about the practicality of choosing Samsung-exclusive finishes. Samsung typically releases exclusive colors for its flagship devices, which are available only through its official web store. T

How to Travel to the Most Remote Office on Earth

In November 2023, Jessica Studer, a 33-year-old research medical doctor and professional pianist from Bremgarten, Switzerland, prepared for her trip to Antarctica’s Concordia research station. Most work trips require a flight and a few nights in a hotel; hers would involve several days of travel and a year at the most remote outpost in the world. Very few people have experience preparing for such an extreme journey. Concordia sits at 10,600 feet above sea level, with winter temperatures plummet

I Found the Best Way to Stop Mosquitos This Summer, and It's Not a Spray or Candle

Longer, hotter summers mean one thing: longer, itchier, angrier mosquito seasons. And if June's sizzling heat waves are any preview of summer's dog days, you're gonna need more than good vibes and a flickering citronella candle to make it through. I was playing it fast and loose with the usual bug defenses: sprays that smell bad and taste even worse and candles that burn out faster than your will to be outside. Then I met my new summer MVP: the Thermacell. It's a compact, affordable, bug-repell

Why Do Swallows Fly to the Korean DMZ?

Since 1953, the 250-kilometer-long artificial boundary of the DMZ has cut through the middle of the Korean peninsula. The demilitarized buffer zone created more than seven decades ago between the two warring states often feels impenetrable and permanent. However, the DMZ is livelier and more fluid than it seems. In fact, much of the DMZ crosses water—oceans, estuaries, and rivers. A quarter of this boundary falls upon the Han River estuary (한강하구), a “neutral” zone according to the Korean Armisti

Aurora Borealis May Hit These 16 States Over the Next 2 Days

Alongside fireworks and drone shows, people will have another excuse to look up at the sky this week, at least in select parts of the US. The sun has graced Earth with another round of solar material, which will interact with our atmosphere and make sections of the sky glow. Of course, we're talking about the aurora borealis, and it'll be visible in 16 states on Tuesday and Wednesday night. Of the two days, Tuesday night into Wednesday morning will be your best shot.

Pentagon may put SpaceX at the center of a sensor-to-shooter targeting network

The Trump administration plans to cancel a fleet of orbiting data relay satellites managed by the Space Development Agency and replace it with a secretive network that, so far, relies primarily on SpaceX's Starlink Internet constellation, according to budget documents. The move prompted questions from lawmakers during a Senate hearing on the Space Force's budget last week. While details of the Pentagon's plan remain secret, the White House proposal would commit $277 million in funding to kick o

The U.S. Space Force Wants Industry Ideas for Space-Based Missile Interceptors

In May, President Donald Trump selected a design for the Golden Dome—a space-based defense system designed to protect the U.S. from foreign missiles. Though some experts consider it a pipe dream, Trump claims he can build it in three years. The United States Space Force is already getting the ball rolling. According to a June 27 request for information (RFI), the Space Force is conducting market research on space-based interceptor capabilities for missile defense. The RFI aims to gather informa

Nothing Just Killed Its Phone's Flashy Glyph Interface. I Think the Replacement Is Better

Nothing just announced its long-awaited "first true flagship," the Nothing Phone 3, and killed off one of its most popular and unique phone features in the process. The flashing lights that crisscrossed the back of its previous phones, known as the Glyph Interface, is gone. In its place is something new -- a round black and white screen on the rear of the phone, adjacent to the cameras, which Nothing is calling the Glyph Matrix. With an interface of monochrome dots, the Matrix can show a range

From selfie mirror to Magic 8 Ball, here’s what you can do with the Nothing Phone 3’s Glyph Matrix

TL;DR The Nothing Phone 3 replaces Nothing’s signature Glyph Interface LED lights with a monochrome micro-LED display called Glyph Matrix. Glyph Matrix supports customizable notifications, app interactions, games, camera countdowns, and live indicators. The device features a dedicated Glyph Button to control these functions. There’s also a red indicator on the back that lights up when video recording. After weeks of teasing and hyping, Nothing has just launched the Nothing Phone 3. Not only
