The Food and Drug Administration has asked COVID-19 vaccine makers to update booster shots to tackle newer omicron variants that are on the rise. It says the manufacturers should add a spike protein component to shots to target the omicron BA.4 and BA.5 variants in addition to the original strain.

An "overwhelming majority" of the FDA's advisory committee voted this week in favor of updating shots with an omicron component, in the hopes of starting to use those modified boosters in the fall. The advisory is only for booster shots and not primary inoculations.

Vaccine makers are essentially playing whack-a-mole with the various strains of COVID-19. Pfizer and Moderna have created versions of their vaccines that target BA.1, the omicron variant that caused a significant upswing in COVID-19 cases during the winter.

However, that strain isn't circulating in the US anymore, according to the Centers for Disease Control and Prevention. Earlier this week, the CDC said BA.4 and BA.5 now account for over 52 percent of COVID-19 infections in the US. That figure is expected to rise in the coming weeks.

As CNBC notes, Pfizer and Moderna released clinical trial data this week showing that the current omicron shots performed better against BA.1 than the original versions of their vaccines in terms of offering a stronger immune response. While the immune response against BA.4 and BA.5 was still said to be robust, the omicron inoculations were less effective against those strains. It's unclear how long it will take vaccine makers to develop shots that take aim at BA.4 and BA.5.

"Vaccine manufacturers have already reported data from clinical trials with modified vaccines containing an omicron BA.1 component and we have advised them that they should submit these data to the FDA for our evaluation prior to any potential authorization of a modified vaccine containing an omicron BA.4/5 component," the FDA said. "Manufacturers will also be asked to begin clinical trials with modified vaccines containing an omicron BA.4/5 component, as these data will be of use as the pandemic further evolves."

Twitch has announced a new feature for creators who want to include other streamers and even viewers on their broadcasts. Up to five guests can join a stream through Guest Star, which works on both desktop and mobile. If a viewer wants to take part in the discussion or ask a question, they can raise a virtual hand and the creator or a moderator may invite them on. This seems to work in a similar fashion to Clubhouse and Twitter Spaces.

While the feature is akin to Clubhouse, Twitter Spaces, Spotify Live, Discord Stage Channels et al, Twitch can set itself apart from those services. Guest Star supports live video as well as audio — this is Twitch, after all.

The platform says Guest Star is easy for both newcomers and experienced streamers to use and it works with software like OBS and Twitch Studio. However, streamers won't need to use a third-party app to host a broadcast with other participants.

Until now, bringing guests on to a broadcast has required a bit of a workaround if creators don't want to simply stream a Zoom, Skype or Discord call. If they prefer to use custom layouts, overlays and branding, it's possible to include remote video feeds from Skype or a web app. Guest Star should streamline things.

Streamers and their moderators can swiftly remove guests at any time and for any reason. Guests will need a Twitch account, which means they can be reported for violating the platform's rules. There are some measures in place to help weed out bad actors before they become a guest. Creators and moderators will be able to look at factors like the age of an account, if it's in good standing and if the user has verified it with a phone number.

Guest Star seems to build on features like Squad Stream, which allows viewers to watch four livestreams simultaneously on the Twitch app or website and jump between those creators' chats. The new feature is about bringing people together on the same channel. Creators might use Guest Star for podcasts, call-in advice streams and even game shows.

While Twitch is most commonly associated with gaming, talk-style content has long been on the rise on the platform. Just Chatting has been the most popular category since the third quarter of 2020, according to data from Streamlabs and Stream Hatchet. 

Twitch says that, in the first five months of 2022 (compared with the same period in 2020), hours watched in the Just Chatting category grew 151 percent, while revenue for streamers who create that type of content rose by 169 percent. It suggested Guest Star may encourage more creators to try their hand at talk-focused content.

At first, Guest Star will only be available to a small number of hand-picked streamers who already create talk content so that Twitch can get some feedback before a broader rollout. Twitch plans to make the feature available to all creators this fall.

Google is updating its password manager to make it easier to use and more consistent across platforms. The tool could also help users make their accounts more secure following the upgrades. For one thing, Google is making the password management experience the same in Chrome and Android settings. It will automatically group together passwords for the same sites and apps.

You'll now be able to add passwords directly to Google Password Manager on top of saving them when you log in to an account. Google suggests Android users will be able to log in to sites faster on Chrome with a touch-to-login feature, which will be available on an overlay on the bottom of the screen. This builds on biometric verification features Google added to Chrome last year.

In addition, Google says it will notify you through the Password Checkup screen if you're using compromised credentials. Android users will see alerts about weak and reused passwords too. If you receive such a warning, it should be easy to correct the issue with the automatic password change feature. Compromised password warnings will be available for Chrome users on iOS, Windows, MacOS, Linux and Chrome OS too.

Last week, Google added the ability for iOS users to set Chrome as their autofill provider. The idea was to make it easier for people who use Google Password Manager to sign in to any app on their iPhone. Google recently introduced the option for Android users to set a home screen shortcut for Password Manager as well.

YouTube is enacting more measures in its battle to cut down on comment spam and channel impersonation. Creators now have access to a new setting for comments in YouTube Studio. They'll be able to select an "increase strictness" option. YouTube says this builds on the "hold potentially inappropriate comments for review" setting and will reduce the number of spam and identity abuse comments. It's a less strict option than requiring manual review for all comments or switching them off completely.

As of July 29th, channels won't be able to hide their subscriber counts. YouTube says this is a tactic commonly used by those pretending to be behind larger and more established channels. Impersonators often leave comments on other videos to bring people over to their fake page. For instance, someone who sees a comment left by a user named MrḂeast (with a special character in place of the "B") might click through to that channel to see it has only 100 subscribers, compared with the genuine MrBeast's 97.7 million subscribers.

YouTube acknowledged that some creators prefer to hide their subscriber count while they're building up an audience. However, it says this move will make things safer for everyone.

Speaking of phony channels that use special characters to imitate more prominent creators, that strategy will soon be a little less effective. YouTube says it's reducing the character set that people can use when updating a channel name. It said that bad actors won't be able to modify their name to ”¥ouⓉube” or some such after the change.

Pokémon Go developer Niantic is laying off eight percent of its workforce, which is said to be around 85-90 jobs. The augmented reality game company has also canceled four projects. CEO John Hanke reportedly wrote in an email to employees that Niantic was “facing a time of economic turmoil” and had to “further streamline our operations in order to best position the company" to weather any future economic turmoil.

“We recently decided to stop production on some projects and reduce our workforce by about eight percent to focus on our key priorities,” a Niantic spokesperson told Bloomberg, which first reported the news. “We are grateful for the contributions of those leaving Niantic and we are supporting them through this difficult transition.”

One of the games that has been shelved is Transformers: Heavy Metal. Niantic and Hasbro announced that title in 2021 and had been testing it in some markets since last summer. Niantic has also canned an immersive theater project called Hamlet. It was working on that project with theater group Punchdrunk, which is behind an immersive production of Macbeth called Sleep No More. The other two shelved projects are called Blue Sky and Snowball.

Niantic hasn't yet been able to recapture the lightning-in-a-bottle success of 2016's Pokémon Go. The company shut down an AR game based on Harry Potter earlier this year. Bloomberg notes that titles based on Catan (which shuttered last year) and Nintendo's Pikmin haven't been successful either.

News of the layoffs and project cancellations comes one day after Niantic announced NBA All-World, a basketball game it's making in collaboration with the NBA and the league's players' association. Meanwhile, the company will soon release an app that will help Pokémon Go players chat with each other. It's also working on an original game called Peridot and collaborating with other companies on AR apps.

Publisher No More Robots has announced that the next game from Crossy Road creator Andy Sum will be released on Steam on July 20th. While Crossy Road is a hit arcade-style title in the vein of Frogger, TombStar takes its cue from bullet hell roguelikes, such as Enter the Gungeon and The Binding of Isaac.

TombStar, which was announced in 2020, is a colorful space Western top-down shooter. There are three characters to choose from, each with their own playstyle. You'll pick up abilities, weapons and perks to aid you in battle against the Grimheart Gang. Each of the worlds has a boss, but since the levels are procedurally generated, each run will be different.

Sony has revealed the three games that all PlayStation Plus subscribers can snap up in July. They are Crash Bandicoot 4: It’s About Time, Man of Medan and Arcadegeddon — a notable leaker once again got all three games spot on.

Crash Bandicoot 4 arrived in 2020 and was the first new mainline Crash game in 12 years. It was pegged as a direct sequel to the original PlayStation 1 trilogy — meaning that it ignored all the PS2 games. Both the PlayStation 4 and PS5 versions will be available, with the latter supporting features like the DualSense controller's adaptive triggers and haptic feedback.

Man of Medan is the first title in Supermassive's Dark Pictures Anthology series. It's an interactive horror game in which your choices determine whether characters live or die. However, we felt it didn't hold up as strongly as the studio's previous game, Until Dawn. Man of Medan is hitting PS Plus just after the arrival of Supermassive's latest game, The Quarry.

Arcadegeddon, meanwhile, is a multiplayer shooter from Illfonic that has both co-operative and player vs. player modes. You'll search for loot and unlock abilities as you take on the evil Fun Fun Co. megacorp, which is using an arcade for real-world weapons testing.

This is the first time Sony has refreshed the games on the lowest tier of the new-look PS Plus since it revamped the service. The company said it will continue to offer Essential tier users a couple of games a month that they'll have access to as long as they remain subscribers. Sony will also update the Extra and Premium lineups in the middle of each month.

Crash 4, Man of Medan and Arcadegeddon will be available to claim on July 5th. Until then, you can still add the current batch of PS Plus Essential titles — God of War (2018), Naruto to Boruto: Shinobi Striker and Nickelodeon All-Star Brawl — to your library.

It's a busy spell for Blizzard, with Diablo Immortal, Overwatch 2 and mobile game Warcraft Arclight Rumble all arriving this year. The studio has another major release lined up in the form of World of Warcraft expansion Dragonflight, which is expected to arrive by the end of 2022. To help get WoW expansions out on time and ensure they meet the bar in terms of quality, Blizzard bought Spellbreak studio Proletariat to bolster its ranks of developers, as GamesBeat reports.

The news comes one day after Proletariat announced it will shut down Spellbreak early next year. The free-to-play game is an intriguing take on the battle royale genre, with players using magical powers instead of guns. The game never took off, though. It had an average player count of 166 on Steam over the last month. Apex Legends, on the other hand, has more than a thousand times as many players at any given time on Steam alone.

More than 100 developers from Proletariat will now be focused on World of Warcraft, though the studio has been working with Blizzard since last month. The Boston-based studio also plans to expand its team.

WoW general manager John Hight has spoken of the difficulties his team has had in hiring to deliver content updates to players more quickly (the publicturmoil at the studio over the last year might have played a role in that). Bringing Proletariat on board should help.

“A big part of caring for our teams is making sure we have the resources to produce experiences our communities will love while giving our teams space to explore even more creative opportunities within their projects,' Blizzard Entertainment president Mike Ybarra said. "Proletariat is a perfect fit for supporting Blizzard’s mission in bringing high-quality content to our players more often.”

Activision Blizzard is itself in the process of being bought by Microsoft for $68.7 billion. Given the ongoing labor and workplace culture issues at the company, there's a bit of irony in Blizzard snapping up a studio called Proletariat.

Amazon has pulled another solid deal out of its hat ahead of Prime Day. Prime members can now snag a bundle of the Echo Show 5 and Ring Video Doorbell for $85. You'd essentially be getting the smart doorbell for free, as Echo Show 5 typically costs the same price. The Ring Doorbell normally costs $100 by itself. The standard price of the bundle is $150, which is already $35 less than the products cost separately.

The current version of the Alexa-enabled Echo Show 5 arrived a year ago. We gave it a score of 85 in our review, finding the decent sound quality and bedside-table size to be plus points. The tap-to-snooze option is useful too. However, the interface perhaps isn't as intuitive as it could be and, while it has a better webcam than the first version of the device, it's still only 2MP.

Meanwhile, the second-gen version of Ring Video Doorbell arrived in 2020. It offers up to 1080p HD video, an improvement over the original model's 720p resolution. You can view a video feed from the device on Echo Show 5 as well as on a phone, tablet or PC. The doorbell can run on battery power alone. It can also be hardwired or connected to a Ring solar charger.

Amazon says the device offers better night vision than the first-gen doorbell as well as adjustable motion zones. There's a privacy zone option that allows you to block out certain parts of the field of view from recordings as well. Given that the second-gen Ring Video Doorbell is two years old, this deal could be an instance of Amazon trying to offload existing stock ahead of a possible next-gen model.

We're fast approaching Prime Day, one of the biggest online shopping events of the year, but Amazon isn't waiting to slash the prices of some of its own products. The company has discounted several Eero 6 routers exclusively for Prime members. The standard Eero 6, for instance, is down from $89 to $71 for Prime members. That matches the lowest price we've seen to date.

As with the other models, the Eero 6 is a mesh router. The price is for a single node. The router supports WiFi 6 with speeds of up to 900Mbps and the ability to connect more than 75 devices. Amazon says the device will cover up to 1,500 square feet. The company's TrueMesh tech prioritizes traffic to certain devices — a TV streaming a movie in 4K will require much more bandwidth than a smart thermostat, for instance. With the Zigbee smart home hub, which is built in, Eero 6 will connect Zigbee-compatible devices to Alexa.

Several other Eero models have dropped to new all-time low prices. Among them is the Eero 6+, which is $90, down from $139. This model supports speeds up to a gigabit and has two 1Gbps Ethernet ports. You may also get faster connectivity thanks to support for 160 MHz client devices.

The Eero Pro 6 also costs less than it ever has to this point. Amazon has lowered the price from $229 to $148. The device can cover 2,000 square feet and it supports speeds of up to 1Gbps.

In addition, the Eero Pro 6E is on sale. It's down to $179, which is $120 off the regular price. As the name suggests, this router supports the WiFi 6E protocol and more than 100 connected devices. It provides speeds of up to 1.3Gbps over WiFi and 1Gbps via Ethernet. Each node covers up to 2,000 square feet. Along with Zigbee products, you can use the Eero Pro 6E as a home hub for Thread devices (Pro 6 has Thread support too.)
