Astronomers Report Increased Possibility of Life on Distant K2-18b Planet

With the help of the James Webb Space Telescope, astronomers say they’re closer than ever to confirming signs of life on a distant exoplanet.

A team of astronomers led by the University of Cambridge say they’re closer to a statistically significant scientific finding that would show that signs of life they’re detecting from the distant exoplanet dubbed «K2-18b» are no accident.

The astronomers used data from the James Webb Space Telescope, which has only been in use since the end of 2021, to detect chemical traces of dimethyl sulfide and/or dimethyl disulfide, which they say can only be produced by life such as phytoplankton in the sea. According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»

The findings were published this week in The Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. 

In the abstract for the research paper, the team says: «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»

K2-18b is 124 light-years away and and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases that chances that their are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms.

The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.

I Finally Gave My Teen the AirPods Pro 2. At $80 Off, They’re Totally Worth It

They’ve given her joy, she hasn’t lost them yet and at 32% off the regular price — I’m a happy bargain hunting father.

My 13-year-old daughter loves her music and her privacy, and for years she has wanted a pair of AirPods. I always considered them too expensive, so I bought her cheaper headphones like the Amazon Echo Buds. After expressing her disappointment in not getting «real» AirPods, she ended up «losing» those cheap headphones… somehow.

So last year, when I saw that the actual Apple AirPods Pro 2 were on sale for $169, I pounced. She’s happy, she uses them every day and she hasn’t lost them yet. Now the Apple AirPods 2 are on sale again, so if you’re looking for a pair of headphones that will satisfy your teen, you might want to consider pouncing too.

Why I didn’t wait for the AirPods Pro 3

Rumors abound that Apple will replace the Pro 2 with an updated Pro 3 version later this year. My kid wanted headphones sooner, so I got her the Pro 2s. But if you’re on the fence, here’s my perspective.

The main improvements to the Pro 3 are said to be heart-rate monitoring like the Beats Powerbeats Pro 2 have, as well as a new design. Other speculation points to improved sound and processing with Apple’s H3 chip, temperature sensors, built-in infrared cameras, a touchscreen on the case, live translation of languages and more. There’s no way to know what they actually will have, but I do know that they’ll be more expensive than the Pro 2 (especially at this sale price). I don’t think those new features are going to be worth the money, however.

Hey, did you know? CNET Deals texts are free, easy and save you money.

You might have a different take, especially if you want heart-rate monitoring on your headphones for fitness sessions or one of those rumored extras. In that case it might be worth waiting to see what the new versions include. The AirPods Pro 3 are expected to be announced in September and on sale soon after.

Why I didn’t get the AirPods 4 instead

Why did I choose AirPods Pro 2 instead of the newer AirPods 4 with ANC? First off, as I mentioned in another article about a different pair of earbuds I bought, I think sealed, in-ear buds are better than open-design models like the AirPods 4. The seal creates another layer of noise isolation and contributes to superior sound quality, and if you want to pay attention to the world you can always engage ambient sound mode, which Apple calls transparency mode. 

Also a factor was the commentary of CNET reviewer David Carnoy, who considers the Pro 2 the best Apple noise-canceling wireless earbuds: «While we’re quite impressed with those new models — and with the AirPods 4 ANC in particular — the AirPods Pro 2 remain arguably the best Apple AirPods you can buy if you don’t mind having silicone ear tips jammed in your ears.»

My daughter uses earplugs all the time to help her sleep, so she definitely qualifies as somebody who’s comfortable stuffing things in her ears. Like her fingers, when I start using words like «sigma,» «skibidi» and «relatable» to try to relate to her.

I asked Carnoy about the Pro 2s potentially not fitting in her kid-size ears and he reassured me that the range of eartips that come with the Pro 2s «now include XS, so they should fit.» 

Should you buy now with threat of tariffs?

It’s no secret that President Donald Trump’s tariffs are leading to higher prices for a lot of things, including electronics. We’re actually tracking the price of the AirPods Pro 2 in our tariff tracker and as of press time the price has actually decreased since January. 

If you’re in the market for AirPods 2 now anyway, now is a good time to buy. A Reuters report from April says AirPods could be subject to a 39% price hike to cover tariff costs, but the tariff situation is fluid, so I wouldn’t use that potential increase as a reason to buy now. If you wait until the new model comes out later this year, the price on the older AirPods Pro 2 might even get lower.

Do AirPods make a great gift?

It took me years to finally understand, but yes, for someone looking for wireless earbuds, AirPods — especially the Apple AirPods Pro 2 — make the perfect gift, regardless of whether you’re a teenage girl or not.

Doom The Dark Ages Review: Blood, Steel and Burnout

Guns and heavy metal weren’t enough this time around.

Doom: The Dark Ages is the third game of the new «Doom» era since the franchise was rebooted in 2016 and was followed up with a second game, Doom Eternal, in 2020. While this newest title makes some big changes to the game, and I do mean «big,» it does feel like it’s lost a bit of that Doom charm that made me giddy whenever I saw the phrase «rip and tear.» 

For this latest go-around, developer id Software tweaked the Doom formula to go beyond just shooting enemies and is far away from the platforming that was found in Doom Eternal. The result is a blend of action that really sings when everything is timed right but also falls flat outside of the action. There’s just a lack of areas where my adrenaline starts pumping compared to the previous Doom games.  

To lay the groundwork for Doom: The Dark Ages, the game takes place before the events of the 2016 reboot. Doomguy, referred to as the Slayer throughout, was transported to Hell following the events of Doom 64 in order to fight the hordes of monsters. Some point after battling demons for billions of years, he’s transported to Argent D’Nur, a different realm inhabited by humans who fight against the hordes of Hell in this epic war with futuristic weapons with a medieval motif. As the Slayer, he’s there to help the humans win and what follows is a very dramatic, almost Game of Thrones-type story but it feels shallow. 

And I get it. Doom wasn’t ever really about the story but it has been since the reboot. What I love about the reboot is that I’m playing as the same character as I was 20 years earlier in my high school computer lab. A character who had returned from the depths of Hell and was being used as a living weapon to defeat the army from Hell once again. Then, in Doom Eternal, we learn how Doomguy was a mythical hero in that other realm and traveling to that realm was this satisfying experience that felt like the equivalent of a heavy metal album cover. 

In Doom: The Dark Ages, I didn’t feel that same excitement to learn more about Doomguy’s past. The attempt at intrigue just didn’t work, so making my way through the chapters was a slog at times. Don’t get me wrong: The action was exciting, most of the time, but it takes a while to get to that pinnacle of where all the new elements of the game fit into place.

Doomguy’s New Toys (and Tricks)

Of those new elements, the most significant is the addition of a shield. It’s weird playing a Doom game with a shield but it’s part of id’s attempt to redefine the gameplay by adding some depth. The shield provides four kinds of actions that are important while playing, including the most obvious one, defense.

Some of the enemies have particularly big guns that can tear you apart if you don’t use your shield. As you might expect, there’s a shield throw, a la Captain America, so you can use it as a weapon. This throw can be an instakill for weaker enemies or a stun for tougher ones as it tears into their bodies. 

Doomguy also has a shield bash that does some damage but acts as a way to quickly dash at enemies as well as break open barriers throughout the levels. Lastly, there’s the shield parry. Some enemies shoot out green projectiles that can be parried back at them, which is required to defeat some enemies. I appreciated that there’s an option to make the parry window more generous or tighter, depending on what works for you. 

Another change is the arsenal available to Doomguy. Doom Eternal introduced a few new weapons along with the franchise mainstays like the Chaingun and BFG 9000. But in Doom: The Dark Ages, it’s all new weapons with the exception of the shotgun that you start with. The new guns are pretty intense but they do have a similar feel to other weapons like the Accelerator in comparison to the Plasma Rifle. 

Each gun has an alternate fire that makes it act like a new weapon. For example, the Shredders feel like a standard machine gun that shoots bolts into enemies. Later in the game, you can unlock the alternate version, called the Impaler, that fires big spikes and acts almost like a non-scoping sniper rifle because it deals huge damage with headshots. Another weapon, the Pulverizer, is most notable for its design, which crushes skulls and shoots out bone pieces in a spread to take out multiple enemies at once. Guns weren’t the only new weapons for Doomguy, as there are also new melee weapons, the most notable being the Flail.

The shield and every weapon can be upgraded via gold, rubies and wraithstones found throughout the levels. This is where the action can get fun because upgrading weapons in a certain way can have different effects on enemies, from dealing damage to nearby enemies to having a longer stun or making enemies drop more ammo or armor. There’s a combination of upgrades that creates this fantastic harmony between the shield and the weapons. There’s a lot of experimentation available for players to make their favorite weapon even more fun to use. 

Big Maps, Bigger Fights

Arguably, the most noteworthy change in Doom: The Dark Ages is the open levels. Previous games were more constrained, with players having to clear out rooms. In this game, there are big maps with multiple areas that need to be cleared to complete the chapter. This allows for a lot of exploration as there are plenty of secrets to find. Enemies are scattered throughout, but there are areas where a barrier will pop up and you’ll have to deal with hordes of demons in a closed-off space similar to the previous Doom games. Like the rest of Doom: The Dark Ages, these levels have a medieval look with some futuristic accents here and there. This style, which is also shown in Doom Eternal, creates a remarkable presentation on the Xbox Series X when combined with the heavy metal music. 

Speaking of presentation, the two «big» additions to the Doom franchise are the dragon and the Atlan mech, which are available on certain levels. The action changes similarly when riding either one. Whether you’re on the dragon or the mech, you progress through the levels and do a combination of attacking and dodging enemies’ attacks. Traveling on both is fun but where the dragon flies throughout the levels and can chase down certain enemies, the Atlan smashes buildings as it fights giant demons. While enjoyable, I have to admit, I didn’t mind them being limited to certain levels; there wasn’t a lot to do with them. 

All the new additions id Software introduced in Doom: The Dark Ages are welcome changes to keep a franchise that’s been around for more than three decades feeling fresh. I still can’t shake the feeling that something’s missing, though. It just doesn’t have the same pull as the last two Doom games. Because of that, it never gave me the same rush while playing. There were stretches where it honestly felt boring, which is wild to say about a Doom game. It definitely picks up in places and delivers some great moments, but I kept wishing there was more meat on the bones — just something that made me care more about this adventure.

Doom: The Dark Ages comes out on May 15 for Xbox, PlayStation and PC, and it’ll be available on Game Pass at launch. Players who purchase the Premium Edition of Doom: The Dark Ages will gain access to the game on May 13.

Palworld Developer Has Removed Game Features Due to Nintendo Legal Pressure

Pocketpair says it’s continuing to evolve its monster-collecting game, even as it strips out features that may be too similar to the Pokemon franchise it parodies.

When it debuted as an early access game in 2024, the popular action/collection videogame Palworld was an instant hit, but it didn’t take a judicial expert to predict that its similarities to Pokemon would invite legal action. That happened about eight months later when Nintendo and The Pokemon Company filed suit, claiming patent infringement.

Now, gamers are seeing some of the effects of that legal threat. Pocketpair, the studio behind the unofficial parody, Some features in the game, such as the use of Pal Spheres (similar to Poke Balls in Pokemon) and gliding with Pals have been patched out of gameplay with updates in November and this month.

In a blog post titled, «Regarding the lawsuit, changes to Palworld and the future,» Pocketpair said the changes «were indeed a result of the ongoing litigation.»

The post goes on to say: «everyone here at Pocketpair was disappointed that this adjustment had to be made, and we fully understand that many players feel the same frustration. Unfortunately, as the alternative would have led to an even greater deterioration of the gameplay experience for players, it was determined that this change was necessary.»

Much of the debate around Palworld’s existence and why it’s facing legal challenges has to do with whether the game itself could be protected legally if it’s considered a parody. That may be why the lawsuit is based on patent infringement, focusing on mechanics of the game, rather than copyright infringement. 

Even with legal action pending, the game’s expansion has not slowed down. It’s available on PlayStation 5, Xbox consoles and PC, and there’s a mobile version still in the works.
