Travel costs have gotten to the point that you can barely cross the street for $50. What you can do with $50, however, is lock yourself into ridiculously huge airfare and hotel deals with a lifetime subscription to OneAir Elite, the AI-powered service that routinely finds prices between 20% to 60% lower than the ones published on the big travel-deal sites like Expedia and Hotels.com.

StackSocial’s 87% off deal on a lifetime subscription to OneAir Elite already takes the price down from $790 to just $100, and then when you use the code TRAVEL at checkout, that discounted price gets cut in half to just $50 (-94%), and it’s a one-time buy that gets you permanent access to OneAir Elite. Chances are it will take you only one booking to cover that $50 cost, and since OneAir Elite gives you up to 10% in credit back on each booking, you might end up getting your lifetime subscription basically for free after just one use.

Let AI Do the Legwork

OneAir Elite is smart booking backed by AI that does powerful, lightning-fast deep dives into airline and hotel sites and even locates the unpublished prices that can usually only be found by travel agents. The price you see on OneAir Elite, which is often hundreds and even thousands of dollars below regular listed prices, is the price you get — there are no hidden fees or extra costs that pop up when you check out. A quick hotel search will send OneAir Elite’s AI engine into over 700 airlines worldwide and over 2 million hotels in search of the very best prices.

Even after you book your trip, OneAir Elite is still working to save you money. OneAir Elite automatically tracks your existing reservations, and if the price drops or an even better deal pops up, it will automatically rebook the same hotel room at the lower cost, or re-ticket your flight, and refund you the difference. And don’t forget, you’re already getting up to 10% back in OneAir Travel Cash Rewards with each booking, so your next trip will somehow be an even bigger bargain.

One Trip Covers Your Bill

You could conceivably earn back your one-time purchase fee for a lifetime subscription to OneAir Elite even if you were to buy it at the full-retail price of $790, if you were to score a phenomenally big deal on airfare and a hotel. But when you’re only paying $100 after StackSocial’s 87%-off deal kicks in, it gets way easier to cover that one-time buy with the money saved on your travel bill. And when you use the code TRAVEL at checkout and cut that number in half to just $50, it’s virtually a lock that you’ll be making that back many times over with just one booking.

Reaching 98% efficiency in a solid state and 94% in solution, the small fluorescent molecule’s design could cut down development time and cost for future applications

A new blue fluorescent molecule set new top emission efficiencies in both solid and liquid states, according to a University of Michigan-led study that could pave the way for applications in technology and medicine.

Able to absorb light and emit it at lower energy levels, fluorescent molecules called fluorophores glow in OLED displays and help doctors and scientists figure out what’s happening in cells and tissues. They need to be solid in displays and many sensing applications, but liquids are typically preferred for biological uses. Most fluorophores don’t work well in both forms, but this one does.

“The fluorescent material reached record-breaking brightness and efficiency with 98% quantum efficiency in the solid state and 94% in solution,” said Jinsang Kim, the Raoul Kopelman Collegiate Professor of Science and Engineering in the U-M Department of Materials Science and Engineering who led the study, which is published in Nature Communications.

Often, engineers designing fluorophores start in solution, exploring the optical properties of individual molecules, but run into problems in their solid-state applications when fluorophore molecules contact each other.

“Fluorophores behave very differently in the solid state, which then requires more rational molecular engineering effort for structural modification,” Kim said “By investigating and establishing a molecular design principle to make fluorophores that are bright both in solution and solid states, we have reduced development time and cost for various future applications.”

The initial discovery of the versatile fluorophore—called TGlu for short—was unexpected for lead author Jung-Moo Heo, U-M postdoctoral research fellow of materials science and engineering.

“TGlu was an intermediate step for another chemical design, but during purification I found it was surprisingly highly emissive, not only in solution but also in solid state,” Heo said.

The discovery led to the systematic study to establish the optimal design. The result was a simple design: a single benzene ring core—six carbon atoms joined in a hexagon. The researchers positioned two groups that give away electrons, called donor groups, across the ring from one another. Next to the donors, they placed two acceptor groups, which withdraw electrons, across the ring from one another.

“This so-called quadrupolar structure symmetrically distributes charge across the molecule, providing stable emission in various environments,” Heo said.

Because the ring has only six points, donor and acceptor groups are positioned next to each other. This spatial arrangement reduces the energy gap compared to other similar molecules within a compact framework, which means the fluorophore needs a relatively small amount of energy to move an electron from the ground state to an excited state—similar to jumping up a rung on a ladder.

However, the molecule’s small size means overall conjugation length remains limited—meaning electrons cannot spread out too far across the molecule. This keeps the absolute energy gap—the distance between ladder rungs—wide enough to emit blue light instead of shifting towards narrower energy gap colors like red.

Typically, small band gaps come with an efficiency drawback. When in the excited state on the higher rung of the ladder, an electron can either emit light as it comes back down to the ground state or lose energy as heat through vibration. Often, small band gaps mean more heat loss, reducing the quantum yield—an efficiency metric expressed as the percentage of absorbed UV light that gets reemitted as visible light relative to the amount lost as heat.

After trying a series of acceptor groups, the researchers found one that stabilizes the excited state. Even with the small band gap, this acceptor group prevents heat loss by restricting access to what are known as conical intersections, which function as “exit doors” for energy leakage. This unexpected behavior, called an Inverted Energy Gap Law, was confirmed both by experiments and quantum chemical simulations.

In the solid state, the acceptor groups, which were intentionally designed to be bulky, prevent the molecules from getting too close to one another which causes fluorophores to lose brightness as energy escapes as heat instead of light, a phenomenon known as quenching.

The small, highly-efficient fluorophore is simple to produce—only requiring three steps—which increases its scalability while reducing production costs.

The current TGlu design fluoresces blue light. As next steps, the researchers will adjust the band gap, and thus the color. Further, while a high quantum yield from light excitation is promising, device performance under electrical excitation requires separate testing due to additional loss mechanisms. Heo also plans to work toward a phosphorescent version of the molecule, as phosphors are overall more energy-efficient than fluorophores, for use in display technology.

Autonomous University of Madrid, University of Valencia, Eberhard Karls University Tübingen and Seoul National University also contributed to this research.

Google Home’s latest update will make it easier to decide who in your household can control your smart home. It comes with a new feature, which Google first started testing last year, that will let you assign people “Admin” and “Member” roles.

People with Admin status have full control of all the devices, services, and users within their smart home, while Members can only use “basic” device controls, like watching the live view of a security camera. However, admins can grant Members additional privileges by giving them “Settings” access, allowing for control over device and home-wide settings. Admins can also turn on “Activity” access so Members can keep tabs on device history and recent events, such as a visitor picked up by a doorbell camera.

Google is also simplifying the process of adding a child under 13 to the Home app. Once you set up your kid with a Google account through Family Link, you can invite them to your Google Home, which will add them as a Member by default.

The previous process involved using either Family Link, Google Home, or Google Assistant settings to add your child’s voice to your smart home before inviting them to your home, and many users struggled to get it to work. It seems Google is now streamlining the process by letting you invite a child to your home through the Google Home app, so long as you add them to your Google family group.

Today, Crucial has sent over their brand new T710 2TB Gen5 NVMe SSD for review. This is the successor to the very fast Crucial T705 that I previously reviewed. Like that drive, the T710 is making a play for the high-end Gen5 SSD market and intends to push the limit of the Gen5 interface, and Crucial is claiming some big performance uplifts from the T705. The high-end market space now has ample competition, so I am interested to see how the T710 holds up. Let us get to the review!

Crucial T710 2TB PCIe Gen5 NVMe SSD

The Crucial T710 2TB comes in a single-sided M.2 2280 (80mm) form factor.

The T710 is available both with and without a heatsink, and as you can see my test drive is the bare drive. The controller is a key difference compared to the T705. The T710 includes a Silicon Motion SM2508 controller, whereas the T705 was based on a Phison chip. This controller is paired with Micron TLC and a 2GB DRAM cache.

The backside of the Crucial T710 2TB contains nothing but labels.

Crucial T710 2TB SSD Specs

The Crucial T710 2TB is available between 1TB and 4TB capacity points.

This 2TB model is rated for 14500 MB/s sequential reads and 13800 MB/s writes. These numbers put the T710 at the top-end of claimed Gen5 performance and outpace both the T705 and the Samsung 9100 PRO, at least on paper. Endurance sits at 600TBW per 1TB of capacity, or 1200TBW for my 2TB drive which is perfectly in line with my expectations. And the warranty is the industry standard 5-years for a top-end drive. All of the specs position the T710 at the very top-end of Gen5 drives, and Crucial is also a very long-lived and respected brand.

Crucial is claiming 42% higher random writes, 28% higher random reads, and 9% higher sequential write performance compared to the T705. They are also claiming a 24% reduction in average power use. When we get to testing we will see how the two stack up.

CrystalDiskInfo can give us some basic information about the SSD and confirms we are operating at PCIe 5.0 x4 speeds using NVMe 2.0.

Test System Configuration

We are using the following configuration for this test:

• Motherboard: MSI MAG X670E Tomahawk
• CPU: AMD Ryzen 9 7900X (12C/24T)
• RAM: 2x 16GB DDR5-6000 UDIMMs

Our testing uses the Crucial T710 2TB as the boot drive for the system, installed in the M.2_1 slot on the motherboard. This slot supports up to PCIe Gen 5 x4. The drive is filled to 85% capacity with data, and then some is deleted, leaving around 60% used space on the volume.

Next, we are going to get into our performance testing.

Postapocalyptic open-world survival game Once Human is launching its Annual Version 2.0: Dreamveil, and developer Starry Studio is hosting a special program to mark the occasion. There will be a celebration of all the game has achieved so far, as well as news and updates about what’s coming in the future. IGN will carry a livestream of the full program, so here’s all the details for how you can watch and what to expect as part of the show.

Once Human Special Program Date, Time, and How to Watch

If you’re in the United States, the program will be streaming at night. It’ll begin on Wednesday, July 2 at 9 p.m. Pacific, which means it’ll be at midnight that night in the Eastern time zone. You can watch it live on any of these IGN channels:

IGN.com (our homepage)

IGN’s Facebook

IGN’s Twitter

IGN’s Twitch

IGN’s YouTube

If you can’t stay up late to watch it live, don’t worry. We’ll save the show in its entirety on our YouTube page, so it’ll be waiting for you the next morning.

What to Expect from the Once Human Special Program

This being the game’s annual version, there’s sure to be a look back at the past year and what’s happened in the Once Human universe since release. That includes the game’s four scenarios so far: the PVE-focused Manibus and The Way of Winter, and the PVP-focused Evolution’s Call and Prismverse’s Clash. It also includes the game’s mobile version that was released in April. There have been rumblings of a console version also being in the works, but nothing official has been confirmed so far. Could that be part of this show?

There have been trailers and dev logs that have given some sense of new content that’s on the horizon, but the special program will go into more detail. We know a nightmare-themed scenario called Endless Dream is already in Early Access, but if you haven’t played it for yourself, expect a deep dive into the new story and deviants you’ll face and new content and locations being added.

We also know a new class system is being introduced with three classes available: Chef, Gardener, and Beastmaster. Expect a breakdown of each of the classes and what makes them unique. There also will be announcements of new events, in-game rewards, and other updates to celebrate the new annual version. Plus, the developers are likely to reveal a roadmap of future content. If you haven’t played Once Human yet and want to give it a try before seeing the updates, you can play it for free right now on PC and mobile.

Meta’s adding another way to help Threads users stay in touch with the latest trending chatter, with new in-stream markers of trending topics that will help to guide users towards rising discussions.

As you can see in this example, Threads is looking to drive more in-the-moment engagement around key events, by signifying trending topics in the Threads feed.

As explained by Meta:

“The Threads highlighter elevates and emphasizes unique perspectives that lead to thoughtful conversations. To start, you’ll see the highlighter in important parts of the app where you discover content, and to mark Trending topics – with more placements coming soon.”

It’s another way to drive more trending discussion, with Threads still working to improve its in-the-moment feel as it seeks to take on Elon Musk’s X.

Which, despite X’s challenges, and Threads’ relative growth, remains a big challenge.

X is still the spiritual home for many live discussion groups, with sports fans, in particular, still heavily aligned to the app.

Indeed, sport remains the single biggest driver of discussion on X, and it’s these groups of embedded, habitual X users that will be tough for Threads to win over.

Because people have made connections on Twitter/X, they’ve established behaviors that align with the platform, they’ve built expanded, international groups of friends and fellow fans, to the point where it’ll be difficult to get them all to migrate to a new app.

So they’ll keep using X, until there’s a clear reason not to. And with Threads thus far not being the greatest facilitator of live, in-the-moment chats, it clearly hasn’t been able to get these audiences across as yet.

Maybe an emphasis on trending topics will help, in driving more topical discussion and engagement, while Meta’s also investing in sports partnerships to bring unique, live content to the app, and improving its algorithmic approach to better emphasize live discussion.

There’s no singular answer on this front, but maybe, through an accumulation of these efforts, Threads will be able to make inroads on this, and build the app into a more active hive of real-time discussion, and a valuable facilitator of trending chats.

It’s not there yet, but elements like this are another small step in that larger direction.    

Finding Fortnite’s Academy Tech Lab locations is a good idea in general, thanks to the loot you can pick up, but you’ll also need to enter them several times to complete one of Chapter 6 Season 3 week 4’s quests. Finding them isn’t enough, though. Clearing the quest also requires you to increase your hero rank first.

Below, we explain where to find Fortnite’s Academy Tech Labs and what to expect inside.

Where to find Academy Tech Labs in Fortnite

The Academy Tech Lab can spawn in a variety of locations around the map, but there is always one guaranteed location — Supernova Academy. The basement of the southeastern building on the Supernova Academy campus counts as an Academy Tech Lab, and, as it’s a POI, will be there every game. In this Academy Tech Lab, you can find the following:

As for the other Academy Tech Labs, their locations can be found on the map. They’re marked on the map by an academy symbol next to a test tube at the beginning of every game.

These labs are underground, and you can enter it via a small staircase that leads you into the side of a drum-shaped structure. Inside, you’ll find the following:

How to increase Hero Rank in Fortnite

To complete the week 4 quest, you’ll need to increase your Hero Rank first and then enter a lab.

You and your squad gain points toward a higher Hero Rank every time you do the following:

We recommend returning a Sprite to a shrine to get a large amount of points in one go or visiting a Scout Spire and defeating henchman as they’re easier to eliminate than other players.
