The truth lies in the past in Silo S3 trailer

In April, we got a short teaser for the third season of Silo, the critically acclaimed Apple TV series based on the trilogy by novelist Hugh Howey, which hinted at a mysterious origin story dating back centuries. Apple TV just released the full trailer, and it looks like our heroine is again facing conflict and danger because she just keeps asking so many inconvenient questions.

As previously reported, Silo is set in a self-sustaining underground city inhabited by a community whose recorded history dates back only 140 years. The outside is a toxic hellscape that is only visible on big screens in the silo’s topmost level. The second season expanded Silo‘s world to incorporate the survivors in the second Silo 17; everyone else died in a revolt to escape to the surface. We discovered that there are 50 silos in all. Meanwhile, another revolution was brewing in Juliette’s (Rebecca Ferguson) original Silo 18 against Holland (Tim Robbins). And even more secrets were revealed.

In the season finale, Juliette returned to her silo and warned the residents not to leave, but she and Holland ended up locked in the incinerator just as it was being fired up. The final scene was a flashback, showing a woman questioning a congressman in Washington, DC, about possible retaliation after the US dropped a dirty bomb on Iran. And that brings us to S3. Per the official premise:

I tested a bunch of Switch 2 screen protectors, and these are the best

A glass screen protector is one of a few essential accessories that I strongly recommend to every Switch 2 owner. In fact, it should be a priority to stick one onto the console’s screen as soon as possible to avoid accidental scratches. 

To test the candidates below, I installed and removed Switch 2 screen protectors on my console at an alarming rate, more than any sane person should, and here are the most important takeaways:

  • Do not buy a flimsy plastic screen protector. They are a waste of money and won’t protect your Switch 2 enough.
  • It’s impossible to tell different brands’ protectors apart once they’re on your screen; product packaging and the installation process are the biggest differences (as well as the key factors that increase cost).
  • Some protectors are glossy and some are anti-reflective, each with its own tradeoffs. For my money, glossy is the way to go. The matte finish looks good, but it reduces the screen’s vivid quality and its viewing angles.

Of the options below, it’s easiest to recommend amFilm’s three-pack of glossy screen protectors. Not only is the pack affordable ($9.99 from Amazon), but the tray also allows for perfect alignment of the glass protector for easy, bubble-free installation. I’ve used this company’s screen protectors on various gadgets for years, and I particularly like its glossy option over the matte finish, since it lets the Switch 2’s screen fully shine through.

amFilm three-pack of glossy screen protectors

My go-to screen protector brand for years has been amFilm. Three glossy tempered glass sheets come in the box, and the tools make installation fairly simple. JSAUX’s model is just as good based on my testing, and just as affordable.

Where to Buy:

AmFilm OneTouch screen protectors (two-pack)

In keeping up with some brands that offer faster installations, amFilm offers a two-pack of glossy protectors that includes a “OneTouch” tray. Remove the protector’s bottom film, attach the tray to your device, and then press gently on the protector until it’s fully applied.

Where to Buy:

Dbrand Prism 2.0 two-pack of glossy screen protectors

Dbrand’s Prism 2.0 includes two glass protectors for the Switch 2, each nestled into plastic cases that fit perfectly around the edges of the console (with the Joy-Con 2 removed). $34.99 is expensive for two protectors, but if simplicity and elegant packaging trump value, then this is a good option.

Where to Buy:

Genki Aegis Shield two-pack of glossy screen protectors

Genki offers a cheaper alternative to Dbrand with the Aegis Shield. It includes two protectors, and the installation process is nearly identical: just align the plastic frame with the console, pull the tab, and run your finger across the exposed section of the frame. Spigen makes a similar product that costs $24.99 for a two-pack.

Where to Buy:

amFilm two-pack of matte screen protectors

Let’s start with one of the most affordable options if you want to go the matte-textured route. AmFilm sells a two-pack of protectors at Amazon for $8.99. The set includes a plastic frame that serves as a guide to align the protector just right. JSAUX makes a similar product that’s the same price.

Where to Buy:

amFilm OneTouch two-pack of matte screen protectors

AmFilm also sells a two-pack with a OneTouch frame for easier installation. Again, keep in mind that opting for matte over glossy will reduce glare, but at the cost of viewing angles as well as the full vivid quality of the Switch 2’s screen. That’ll be an acceptable tradeoff for some, but not all people.

Where to Buy:

Update, June 2nd: Adjusted prices as needed.

Number of suspected Ebola cases falls by hundreds as testing ramps up

The estimated size of the Ebola outbreak in the Democratic Republic of the Congo has fallen by hundreds of cases as outbreak response efforts have ramped up and increased testing has ruled out illnesses.

On Tuesday, a representative for the World Health Organization confirmed to Reuters that Congolese authorities are now reporting 437 cases in the DRC, including 321 confirmed cases and 116 suspected. That's a significant difference from the case count the WHO relayed Friday, which totaled 1,041 cases, including 135 confirmed cases and 906 suspected. Over the weekend, the director-general of the Africa Centres for Disease Control and Prevention, Jean Kaseya, also wrote in an op-ed that there were more than 1,100 suspected cases.

The number of deaths has also been lowered to 48 confirmed deaths. On Friday, the WHO had reported 241 deaths, including 18 confirmed and 223 suspected.
