NASA’s Selections for the Most Scientifically Precise Science Fiction Films

in the medical series “The Pitt,” which effectively reveals the physical and psychological challenges faced by healthcare professionals. 

In terms of science fiction, NASA researchers have categorized both unrealistic and plausible films during a gathering at NASA’s Jet Propulsion Laboratory (as reported by Smithsonian Magazine). They should be the experts, right? Here’s the complete list of the most credible and likely films:

1. “Gattaca” (1997)
2. “Contact” (1997)
3. “Metropolis” (1927)
4. “The Day the Earth Stood Still” (1951)
5. “Woman from the Moon” (1929)
6. “The Thing from Another World” (1951)
7. “Jurassic Park” (1993)

The most credible film is “Gattaca,” from 1997, which is so well-crafted in its representation of modern genetics that scientists have built upon the concept with a insightful 2022 publication. Additionally, “Contact,” featuring Jodie Foster, is inspired by a novel authored by Carl Sagan, a genuine astronomer and scientist. It appears he delayed the production as he desired it to be highly precise (via <a href="https://faroutmagazine.co.uk/how-scientifically-accurate-is-contact-according-to-nasa/" target="_blank

The Security of Applying WD-40 on Electronic Gadgets

If you’ve ever found yourself needing to remove a stubborn screw or lubricate the track of a sliding-glass door, it’s likely you’ve reached for a can of WD-40 to accomplish the task. A versatile solution, WD-40 is frequently utilized as a lubricant, but it’s also effective in preventing rust, corrosion, and moisture. This practical product serves well for home, garden, and automotive uses, and even casual tech enthusiasts can discover multiple applications for a can of Water Displacement, 40th Formula (the full meaning of the acronym).

However, DIY computer assemblers and vintage radio restorers should take caution: the conventional WD-40 Multi-Use Product is not meant for use on electronics. You might be wondering what the issue is. Regular WD-40 is highly flammable, and the residue it leaves can conduct electricity.

Even if you spray it on a power supply or exposed circuits and everything appears to operate normally at that moment, the leftover residue is essentially a ticking time bomb. After a few days or weeks, it can cause a short circuit, damage the entire component, or— in the worst-case scenario— ignite an electrical fire.

Maintenance that doesn’t lead to malfunction

We comprehend why you might have assumed it was acceptable to use WD-40 on your tech device— after all, how else could you remove all the dust and grime from your electronic components? Beyond the fire and electrical risks posed by WD-40, that oily film it leaves behind may disturb the dirt you’re trying to clean in the short term, but it can also serve as a magnet for future debris to adhere to.

Fortunately, various products tailored for deep-cleaning electronics are available on the market, including one made by the WD-40 brand itself. Introducing WD-40 Specialist Contact Cleaner, a spray-on solution specifically designed for use with circuit boards, electric panels, and control interfaces. The red precision nozzle allows you to spray oil and dirt from hard-to-access areas, and the product dries quickly, leaving no residue.

Alternatively, you can purchase a bottle of 90% isopropyl alcohol or higher for cleaning electronics. It’s generally safe as the liquid evaporates rapidly and does not leave any residue behind. Avoid anything 70% or lower, which contains a lot of water, persists on surfaces, and takes a long time to evaporate— not ideal for sensitive electronics.

Keep your tech clean without damaging it

There are additional brands that create safe and reliable contact cleaners for electronic devices, many readily available on Amazon. This CRC QD Electronic Cleaner is among the top-rated contact cleaners on the site (4.8 out of five stars, based on more than 14,000 reviews), and it’s designed to leave zero residue while protecting against contact failures.

We recognize the importance of keeping your electronics free from dust and lint. Our guides on safely cleaning your computer’s USB ports and effectively deep cleaning your iPhone highlight tools such as cotton swabs, microfiber cloths, and isopropyl alcohol— all equally effective at eliminating dirt and grime from circuit boards and other sensitive electronics.

Additionally, we provide guidance on how frequently you should clean your computer, recommending the use of a soft-bristled brush to remove dirt and dust clumps. This is another excellent accessory to include in your toolkit— ideal for not only clearing crud from your laptop or desktop, but also for giving all your other electronics a well-deserved cleanup.

Comprehending the Black Dot on Your iPhone Display and How to Turn It Off

Staying updated with your phone’s software is one of the top methods to guarantee that your device performs at its best. Occasionally, an update can bring features and settings you’ve never encountered before, similar to those seen on iPhones with the launch of iOS 18.4 earlier this year. Alongside the standard bug fixes and system enhancements, this iOS version also introduced a new UI feature: a black dot located to the right of the Dynamic Island.

Surprisingly, the black dot is simply a visual upgrade for two privacy indicators that debuted with iOS 14, namely the orange and green dots. A green dot signifies that an iPhone app is accessing your camera, while an orange dot indicates that an app is utilizing your phone’s internal microphone. In iOS 18.4, developers relocated the indicators from the Dynamic Island and added a black background to both, improving their visibility.

To remove the green or orange dots with a black background, you just need to close the app that is accessing your iPhone’s camera or microphone. If you’re uncertain which software is causing these indicators to appear, swipe down from the top-right corner of the screen to access Control Center. Here, you will find usage details for active apps, including which software is using the camera or microphone.

You cannot turn off the dots, but you can manage your privacy.

When looking for privacy indicators on phones, such as the green dot on Android devices, it is wise also to monitor which apps your phone is operating. Regardless of whether you’re using an iPhone or Android, a privacy indicator might be your sole warning of potential malware running in the background, especially if you are confident that your apps are not causing it.

How might it have appeared initially? There are numerous ways, one of which is through a compromised connection. This is why it’s advisable to steer clear of public USB charging stations, or at the very least, use a protective accessory like JSAUX’s USB Data Blocker if you absolutely need to charge your device and lack a portable charger.

Regrettably, if the green or orange dot bothers your iOS experience, there’s no universal off switch for the indicators. However, you can individually grant and revoke camera and microphone access. To do this, go to Settings, tap Privacy & Security, and select Camera or Microphone. Once you revoke an app’s access to the camera or microphone from the list, the indicator dots should no longer show up when you use that software, and they will remain off for any apps you have not authorized.
