A Brain Mechanism Explains Why People Leave Certain Tasks for Later


How does procrastination arise? The reason you decide to postpone household chores and spend your time browsing social media could be explained by the workings of a brain circuit. Recent research has identified a neural connection responsible for delaying the start of activities associated with unpleasant experiences, even when these activities offer a clear reward.

The study, led by Ken-ichi Amemori, a neuroscientist at Kyoto University, aimed to analyze the brain mechanisms that reduce motivation to act when a task involves stress, punishment, or discomfort. To do this, the researchers designed an experiment with monkeys, a widely used model for understanding decisionmaking and motivation processes in the brain.

The scientists worked with two macaques that were trained to perform various decisionmaking tasks. In the first phase of the experiment, after a period of water restriction, the animals could activate one of two levers that released different amounts of liquid; one option offered a smaller reward and the other a larger one. This exercise allowed them to evaluate how the value of the reward influences the willingness to perform an action.

In a later stage, the experimental design incorporated an unpleasant element. The monkeys were given the choice of drinking a moderate amount of water without negative consequences or drinking a larger amount on the condition of receiving a direct blast of air in the face. Although the reward was greater in the second option, it involved an uncomfortable experience.

As the researchers anticipated, the macaques’ motivation to complete the task and access the water decreased considerably when the aversive stimulus was introduced. This behavior allowed them to identify a brain circuit that acts as a brake on motivation in the face of anticipated adverse situations. In particular, the connection between the ventral striatum and the ventral pallidum, two structures located in the basal ganglia of the brain, known for their role in regulating pleasure, motivation, and reward systems, was observed to be involved.

The neural analysis revealed that when the brain anticipates an unpleasant event or potential punishment, the ventral striatum is activated and sends an inhibitory signal to the ventral pallidum, which is normally responsible for driving the intention to perform an action. In other words, this communication reduces the impulse to act when the task is associated with a negative experience.

The Brain Connection Behind Procrastination

To investigate the specific role of this connection, as described in the study published in the journal Current Biology, researchers used a chemogenetic technique that, through the administration of a specialized drug, temporarily disrupted communication between the two brain regions. By doing so, the monkeys regained the motivation to initiate tasks, even in those tests that involved blowing air.

Notably, the inhibitory substance produced no change in trials where reward was not accompanied by punishment. This result suggests that the EV-PV circuit does not regulate motivation in a general way, but rather is specifically activated to suppress it when there is an expectation of discomfort. In this sense, apathy toward unpleasant tasks appears to develop gradually as communication between these two regions intensifies.

Beyond explaining why people tend to unconsciously resist starting household chores or uncomfortable obligations, the findings have relevant implications for understanding disorders such as depression or schizophrenia, in which patients often experience a significant loss of the drive to act.

However, Amemori emphasizes that this circuit serves an essential protective function. “Overworking is very dangerous. This circuit protects us from burnout,” he said in comments reported by Nature. Therefore, he cautions that any attempt to externally modify this neural mechanism must be approached with care, as further research is needed to avoid interfering with the brain’s natural protective processes.

This Backyard Smoker Delivers Results Even a Pitmaster Would Approve Of


While my love of smoked meats is well-documented, my own journey into actually tending the fire started just last spring when I jumped at the opportunity to review the Traeger Woodridge Pro. When Recteq came calling with a similar offer to check out the Flagship 1600, I figured it would be a good way to stay warm all winter.

While the two smokers have a lot in common, the Recteq definitely feels like an upgrade from the Traeger I’ve been using. Not only does it have nearly twice the cooking space, but the huge pellet hopper, rounded barrel, and proper smokestack help me feel like a real pitmaster.

The trade-off is losing some of the usability features that make the Woodridge Pro a great first smoker. The setup isn’t as quite as simple, and the larger footprint and less ergonomic conditions require a little more experience or patience. With both options, excellent smoked meat is just a few button presses away, but speaking as someone with both in their backyard, I’ve been firing up the Recteq more often.

Setting up the Recteq wasn’t as time-consuming as the Woodridge, but it was more difficult to manage on my own. Some of the steps, like attaching the bull horns to the lid, or flipping the barrel onto its stand, would really benefit from a patient friend or loved one. Like most smokers, you’ll need to run a burn-in cycle at 400 degrees Fahrenheit to make sure there’s nothing left over from manufacturing or shipping. Given the amount of setup time and need to cool down the smoker after, I would recommend setting this up Friday afternoon if you want to smoke on a Saturday.

Make the Most of Chrome’s Toolbar by Customizing It to Your Liking


The main job of Google Chrome is to give you a window to the web. With so much engaging content out there on the internet, you may not have given much thought to the browser framework that serves as the container for the sites you visit.

You’d be forgiven for still using the default toolbar configuration that was in place when you first installed Chrome. But if you take a few minutes to customize it, it can make a significant difference to your browsing. You can get quicker access to the key features you need, and you may even discover features you didn’t know about.

If you’re reading this in Chrome on the desktop, you can experiment with a few customizations right now—all it takes is a few clicks. Here’s how the toolbar in Chrome is put together, and all the different changes you can make.

The Default Layout

Extensions are always easily accessible in Chrome.

Take a look up at the top right corner of your Chrome browser tab and you’ll see two key buttons: One reveals your browser extensions (the jigsaw piece), and the other opens up your bookmarks (the double-star icon). There should also be a button showing a downward arrow, which gives you access to recently downloaded files.

Right away, you can start customizing. If you click the jigsaw piece icon to show your browser extensions, you can also click the pin button next to any one of these extensions to make it permanently visible on the toolbar. While you don’t want your toolbar to become too cluttered, it means you can put your most-used add-ons within easy reach.

For the extension icons you choose to have on the toolbar, you can choose the way they’re arranged, too: Click and drag on any of the icons to change its position (though the extensions panel itself has to stay in the same place). To remove an extension icon (without uninstalling the extension), right-click on it and choose Unpin.

The Piracy Problem Streaming Platforms Can’t Solve

The Piracy Problem Streaming Platforms Can’t Solve


“The trade-off isn’t only ethical or economic,” Andreaux adds. “It’s also about reliability, privacy and personal security.”

Abed Kataya, digital content manager at SMEX, a Beirut-based digital rights organization focused on internet policy in the Middle East and North Africa, says piracy in the region is shaped less by culture than by structural barriers.

“I see that piracy in MENA is not a cultural choice; rather, it has multiple layers,” Kataya tells WIRED Middle East.

“First, when the internet spread across the region, as in many other regions, people thought everything on it was free,” Kataya says. “This perception was based on the nature of Web 1.0 and 2.0, and how the internet was presented to people.”

Today, he says, structural barriers still lead many users towards illegal platforms. “Users began to watch online on unofficial streaming platforms for many reasons: lack of local platforms, inability to pay, bypassing censorship and, of course, to watch for free or at lower prices.”

Payment access also remains a major factor. “Not to mention that many are unbanked, do not have bank accounts, lack access to online payments, or do not trust paying with their cards and have a general distrust of online payments,” Kataya adds.

Algerian students also share external hard drives loaded with television series, while in Lebanon streaming passwords are frequently shared across households. In Egypt, large Telegram channels distribute content across different genres, including Korean dramas, classic Arab films and underground music.

“We grew up solving problems online,” says Mira. “When something is blocked, you find a way around it. It’s … a fundamental human instinct.”

Streaming Platforms Adapting

Andreaux says StarzPlay has tried to address some of the payment barriers that limit streaming adoption in the region. “StarzPlay recognized early that payment friction was a regional barrier to adoption,” he says. “That’s why we invested in flexible subscription models and alternative payment methods, including telecom-led billing options that make access easier across different markets.”

At the same time, international media companies are working together to combat piracy through the Alliance for Creativity and Entertainment (ACE), a coalition of film studios, television networks and streaming platforms that targets illegal distribution of films, television and sports content. Its members include global companies such as Netflix as well as regional players like OSN Group, which operates the streaming service OSN+ across the Middle East and North Africa.
Kataya notes that legitimate streaming platforms are still expanding across the region. “The user base of official streaming platforms has been growing in the region,” he says. “For example, Shahid, the Saudi platform, is expanding and Netflix has dedicated packages for the region.”

“Other players, like StarzPlay and local platforms in Egypt, are also finding their place,” Kataya adds. “Social media also plays a huge role, especially when a film is widely discussed or controversial.”

Piracy carries legal and security risks, Andreaux says. “Rather than just ‘free streaming’, piracy exposes consumers to malware and insecure payment channels,” he says. “It also weakens investment in local content by depriving creators of revenue and reducing jobs.”

But the structural barriers described by users across the region remain. For many viewers in North Africa and the Levant, the challenge is not choosing between piracy and legality—it is whether legitimate access exists at all.
