Scientists tracked 12 people in Antarctica for 10 months—what happened could shape future Mars missions

A ten-month Antarctic experiment found that astronauts may struggle not only with loneliness but also with spending too much time around the same people. Frequent contact was linked to greater tension and mistrust, while the crew increasingly divided into cultural and language-based groups.

Large File Support

19 years ago I bought version 6 of some software. I just started using it again after not using it for 17 years or so and it is at version 26 and my old registration is still valid so I still have the pro version! They don’t even sell this software anymore, they just rent it but they are honoring my old purchase!

The software is EmEditor. I originally used it for UTF-8 support but this support became more common with editors. I just used it because I was working with a fairly large text file at 12.5 GB. My main editor is 32-bit and couldn’t remotely handle this. I then tried Windows Notepad and Microsoft Word and they also laughed at the idea of editing such a big file.


EmEditor is capable of opening very large files — up to 16 TB or 1,099 billion lines — with only a little memory, leaving you free to work as large or small as you please.

What Samsara’s Insider Selling Really Signals For IIoT

Samsara insiders have sold a net $57 million over the past year, including major sales by the CEO and board member Marc Andreessen — while analyst coverage remains strongly bullish.

The gap between public optimism and sustained private divestment is the signal worth watching.

For manufacturers and fleet operators evaluating IIoT platforms: net insider selling over a 12-month window is a legitimate due-diligence input. It doesn’t override growth metrics, but it shouldn’t be dismissed as pure noise either.

Samsara’s insider selling tops $57M as analysts stay bullish. Here’s what the pattern really signals for industrial IoT buyers and investors.

Sharks With Headlights: Glowing Sharks Use Their Own Shine to Hunt Prey, New Evidence Suggests

In the deep, dim ocean, a world of eat-or-be-eaten, lighting up may seem like a counterintuitive survival strategy.

Nevertheless, it helps many animals hide from predators that might strike from below – a shine that conceals the shadow they cast against the faint light filtering down from above.

Now, however, scientists have found evidence that one of the most stunning bioluminescent animals in the ocean may have been using its light in another way all along.

A precise neuronal mechanism allows the brain to plan future routes to remembered goals

When humans and other animals move through familiar or unfamiliar environments, their brains rely on numerous intricate neural processes to decide which path to take next. Past studies have identified a specific population of cells in the hippocampus, a structure deep within the brain, that appears to play a key role in spatial navigation.

These cells, called place cells, become active when an animal either visits or thinks about a specific location. Place cells often fire in rapid sequences during so-called theta oscillations (i.e., rhythmic brain activity patterns that cycle approximately 4–12 times per second). These rapid bursts of sequential place cell activity, also known as theta sweeps, were previously associated with the mental evaluation of possible future routes.

Two distinct research teams based at Cornell University and University College London recently shed new light on the contribution of theta sweeps to spatial navigation.
