If you have a scrolling problem, you’ve probably tried every productivity app. App timers, grayscale mode, deleting the apps entirely, only to reinstall them twenty minutes later. None of it works because willpower alone is a terrible strategy.

Cat Gatekeeper has a better idea. Instead of guilt-tripping you, it sends a chubby ginger cat to physically take over your screen when you’ve spent too much time on social media, and I love it.

How does it work?

The setup is simple. Install the Chrome extension, set your usage limit, and set your break time. Once you hit your limit on social media apps like X, Instagram, TikTok, or YouTube, the cat appears and takes over your screen.

Developed by an X user, konekone2026, the concept is not novel, but the execution is. I have tried several website-blocking services, but Cat Gatekeeper has instantly become my favorite. The way the cat saunters onto the scene and simply plops down with its big fat tummy heaving with each breath is just magical.

I like that the timer only counts down when the social media tab is actually active. Switch to another tab or app, and it pauses. This applies to both your usage and break time countdowns. It ensures that you are not unfairly punished, or able to skip the break timer by simply switching to something else.

Is it actually effective?

Honestly, it won’t stop you from scrolling, but it does provide a gentle reminder to take a break. The cat is genuinely adorable, which makes taking the break feel less like punishment and more like a reward.

You get a forced break, a cute cat, and a fresh timer ready to go when you’re done. What more could you want?

It’s free, has no ads, and according to the developer, the extension doesn’t collect any data. You can install Cat Gatekeeper from the Chrome Web Store. Give it a try and let me know if the cat actually made you take a break.

While sediment cores several meters long had been recovered on earlier expeditions in the central Arctic, there is no scientific consensus on how old the deposits actually are or whether sea ice ever completely disappeared in summer. 

To decode the Arctic’s climate archive, Knies brought a team of experts from various disciplines onboard the Kronprins Haakon to dig deeper and obtain fresh samples they could subject to the latest analytical techniques.

Samples await paleomagnetic dating. Like tiny compass needles, iron-rich particles align with Earth’s shifting magnetic field as they settle on the seabed. By measuring their orientation, researchers can estimate the age of the different sediment layers.

Under the microscope, PhD student Paulina Romel picks shells of unicellular foraminifera from a sample. The chemical composition of these microfossils can give clues about the age of the sediment and the surface water temperature when the organisms were still alive. “These are really cool creatures!” says Romel.

Agathe Ollive, a geochemist from the Alfred Wegener Institute in Germany, takes water samples from a CTD rosette, an instrument package that measures conductivity (salinity) and temperature at various depths. She uses certain elements to trace the inflow of fresh water and seawater from rivers and adjacent ocean basins into the Arctic. “I didn’t expect there to be so little ice up here,” Ollive says. She is worried about how the Arctic will look 20 years from now.

Some of this work was done while the researchers were still at sea. Now, at their home laboratories, they are finalizing their analysis of the seafloor samples. One important task is dating the sediments, which may be up to 2 million years old. The team uses a combination of methods to do this, including measuring magnetization, the decay of radioactive elements, and the exposure of mineral grains to sunlight before sinking to the depths. Once they can place them on a timeline, the materials in the cores will help researchers paint a picture of what the Arctic Ocean looked like in times that were warmer than today. For example, the presence or absence of the molecule IP25, which is produced exclusively by ice algae, could tell them how far the sea ice receded at a given time.

At the end of the study, the team hopes to have data that could improve climate projections for a future ice-free “blue Arctic,” helping us understand how it could affect marine life and carbon storage, Atlantic Ocean circulation, or extreme weather events in Europe and North America.
