A protein called TRAILshort may act as a central immune brake that limits T-cell responses and CAR-T therapy. Cancer cells can weaken the immune system by producing a protein that prevents its most important defenders from attacking. Mayo Clinic researchers have identified how this protein works, revealing a possible target for treatments designed to improve [...]

Seit Apple sich im Jahr 2003 von der Macworld New York zurückgezogen hat, ist der August traditionell ein eher ruhiger Monat, was Apple-Neuheiten angeht – für die Apple-Gerüchteküche ist er jedoch von großer Bedeutung.
Da im September das bevorstehende iPhone-/Apple-Watch-Event ansteht, erwarten wir in diesem Monat keine neue Hardware. Wenn Sie es jedoch mögen, wenn Ihnen Überraschungen vorweggenommen werden, ist der August ein guter Monat für Apple-Gerüchte. Die Produktion der neuen iPhones und Apple Watches läuft an, sowie manchmal anderer Hardware, deren Veröffentlichung Apple für den Herbst plant. Und mit der Massenproduktion gehen auch Leaks einher.
Daher wird der August wahrscheinlich der Monat sein, in dem wir uns das bestmögliche Bild von den kommenden iPhones, Macs und anderen Geräten machen können, deren Veröffentlichung Apple für diesen Herbst geplant hat. Außerdem befinden sich die neuen Betriebssysteme bereits weit fortgeschritten in der öffentlichen Beta-Testphase – diese wird fortgesetzt, doch große Überraschungen sind dabei wohl nicht zu erwarten.
Der August ist auch Tim Cooks letzter Monat als CEO, da John Ternus diese Rolle am 1. September übernimmt. Und „Ted Lasso“ ist zurück!
Wir rechnen im August nicht mit neuer Hardware (schließlich steht das große iPhone-Event im September kurz bevor), aber es wird jede Menge Software zu entdecken geben, wenn Sie am Beta-Programm teilnehmen.
Derzeit befinden wir uns bei der vierten Beta-Version für alle OS-27-Updates: iOS, macOS, iPadOS, watchOS und visionOS. Neue Versionen werden etwa alle zwei Wochen an Entwickler ausgegeben, wobei die öffentlichen Beta-Tester die gleichen Builds mittlerweile ein oder zwei Tage später erhalten. Rechnen Sie also im August mit zwei weiteren Beta-Versionen, möglicherweise sogar drei.
Zu diesem Zeitpunkt sind die meisten wichtigen Funktionen und Änderungen in den OS-27-Beta-Versionen bereits vorhanden, und Apple arbeitet nur noch daran, Details zu verfeinern, Fehler zu beheben und die Leistung zu optimieren. Wir werden die Builds zudem nach möglichen versteckten Informationen zu den kommenden Produkten durchforsten.
Folgende Serien und Filme erwarten wir im August auf Apple TV:
„Ted Lasso“ (Staffel 4): Apples großer Durchbruchserfolg kehrt nach einer dreijährigen Pause zurück. 5. August
„Women in Blue“ (Staffel 2): In der zweiten Staffel begleitet die Serie María, die inzwischen zum Lieutenant befördert wurde, während sie sich hin- und hergerissen sieht zwischen den Regeln, zu deren Einhaltung sie sich verpflichtet hat, und dem unerbittlichen Drang nach der Wahrheit. 12. August
„The Dynasty: UConn Huskies“: Eine Sportdokumentation über das erfolgreichste Team im College-Basketball. 21. August
„Stillwater“ (Staffel 5): Eine Zeichentrickserie für Kinder, in der ein weiser Panda namens Stillwater seinen menschlichen Nachbarn neue Perspektiven auf die Welt, auf sich selbst und aufeinander vermittelt. Termin
Dark Matter (Staffel 2): Die gefeierte High-Concept-Science-Fiction-Serie kehrt zurück. 28. August

When archaeologists began excavating a large ancient settlement near Tel Aviv in 2012, among the many discoveries at the 9000-year-old site were as many as 400 locally crafted artifacts made from obsidian.
One reason this was so significant is that this dark volcanic glass is absent in Northern Israel, and discoveries in the region ultimately helped trace it back to quarry sites in central Turkey. Although the importation of non-local source materials in the ancient world is not particularly unusual, another discovery archaeologists soon made proved more baffling: the appearance of unusual engravings on several arrowheads produced from this ancient Anatolian obsidian.
Now, a rare collection of these uniquely engraved projectiles is providing archaeologists with deeper insights into the presence of a mysterious symbolic tradition that was practiced long ago by some of the earliest farming communities 9,000 years ago.
In a recent study published in Plos One, an international research team examined a collection of eleven previously undocumented arrowheads unearthed at Tepecik-Çiftlik, a Neolithic settlement in Cappadocia. These ancient projectiles are each decorated with carefully carved incisions, the purpose of which remains baffling to archaeologists.
The rare discoveries have been grouped with an exceptionally uncommon class of ancient stone artifacts, which have only been found in Central Anatolia, and were only known to have been produced during the late eighth and seventh millennia BCE. With the inclusion of the new set, which became the focus of the team’s study, the total number of these unusual artifacts rises to 43 that have been documented across the region.
These projectile points are unique among arrowheads, which are one of the most common artifacts from the ancient world, since the purpose of their engravings remains unclear. A range of theories have been proposed, which include the idea that some may have been personal identifiers; other theories propose clan symbols, hunters’ marks, or even ritual or symbolic reasons for their presence on the ancient obsidian weapons.
Study authors Alice Vinet and Denis Guilbeau took a cautionary approach, warning that current evidence remains insufficient to draw any firm conclusions about the unusual markings.
“The analysis of these incised arrowheads, along with the limited archaeological and ethnographic comparisons available, calls for a cautious interpretation,” the authors write.
To try to understand the possible meaning behind these markings, the researchers conducted a detailed analysis that examined technological, functional, and iconographic aspects of the markings. Based on macroscopic evaluations, the source of the obsidian was determined to likely come from volcanic sources at Göllüdağ and Nenezi Dağ in Turkey, both of which are recognized by archaeologists as sources of high-quality volcanic glass during the Neolithic.
Despite their simplicity, the engraved designs on the samples the team examined showed significant diversity. However, no consistent relationship emerged between the incisions and the raw materials used to craft the arrowheads; nor were any connections apparent regarding manufacturing techniques, shapes, or in terms of use patterns.
One potentially important observation was that some of the engravings appear to have been made before the tools were completed, while other examples showed signs of engraving after completion. This suggests there had been no standardized stage during production when the markings were applied that may provide clues in terms of a possible meaning behind the markings (such as a kind of label or other marking that might have been used to designate individual samples before being knapped into projectiles).
Despite the variations between samples, their overall comparison with other samples recovered from Central Anatolian sites in the region did appear to show recurring design components, suggesting continuity that could indicate a shared visual tradition that was incorporated across multiple ancient communities in the area.
Another intriguing aspect of the team’s study involves the locations where they were recovered. As opposed to simply being found in ceremonial contexts, some of the projectiles were found in the remnants of homes, while others were found in lithic production sites or during archaeological surveys, which seems to suggest the engraved obsidian arrowheads saw use in a wide range of everyday activities and practices.
Still, based on their rarity and constrained geographic distribution, the persistence throughout several centuries of Anatolian prehistory seems to point to a unique cultural practice in the region, the full significance of which remains unknown. For now, their presence offers a unique look at the ancient hunters and farmers from one of the earliest settled societies, suggesting that even artifacts with largely practical uses may have held greater significance in terms of the symbolic importance they held for their ancient makers.

The GuliKit KK3 Max might look like a standard controller, but it has plenty of extras and features on board.
Adopting the familiar form of the Xbox’s gamepad, the KK3 Max doesn’t exactly push the boundaries in terms of design. But given how comfortable and convenient the shape and layout are, it’s hard to complain about its lack of originality.
There are also a few extra flourishes that add some interest. The matte white finish of my review unit was rather fetching, while the front panel is incredibly smooth, smoother than any other I’ve felt before. Its construction also feels quite solid, rivaling the builds of the best PC controllers.
This premium feel extends to the buttons, since there’s very little wobble to any of them. The same can be said of the various sets of levers for the four back buttons, although a fair amount of force is required to insert them.
Despite the lack of software, there are still plenty of input-related customizations and settings available via various button combinations. These range from basic adjustments, such as the vibration intensity and stick sensitivity, to more advanced features, such as motion control and macro recording.
The overall performance of the KK3 Max is pretty good. Most of the buttons are responsive and satisfying to press. The triggers offer a fair amount of control, although I found their travel distance a little too short for my preferences. The sticks also lack the precision of the best, although they move easily and quickly. Motion controls are also inconsistent: I found they performed well with Nintendo Switch games, but were less effective on PC and mobile titles.
I’m happy to report that I had no issues with connectivity on any system I tried the KK3 Max with. Whether it was to my PC via the USB dongle or to my Switch and Android tablet via Bluetooth, the KK3 Max connected quickly to them all and I didn’t experience any dropouts or lag. Hotswitching between devices is also easy thanks to the dedicated button for this purpose, although it can take several presses for the button to respond.
The current multiplatform controller market is certainly a competitive one, with an increasing number of entrants offering increasingly better value. At $79.99 / £65.99 / AU$113.95, the KK3 Max is dangerously close in price to some real standouts, such as the Steam Controller and the GameSir G7 Pro 8K, and more expensive than the 8BitDo Pro 3, another highly capable controller. It mightn’t quite match up to its cohort, but the KK3 Max is still a gamepad to consider if you prefer onboard adjustments and like to have plenty of back buttons.
The GuliKit KK3 Max costs $79.99 / £65.99 / AU$113.95 and is available now from Amazon. Three colorways are available: black, white, and grey.
This pricing places the KK3 Max at the premium end of the market. It comes close to some big names in this space, such as the new Steam Controller. This has the advantage of touchpads for controlling the mouse cursor, and we found its gyroscope controls performed very well, unlike the KK3 Max’s. It isn’t compatible with the Switch or Switch 2, though.
The KK3 Max is also more expensive than the 8BitDo Pro 3, which has class-leading performance. We particularly loved its smooth analog sticks and triggers, as well as its phenomenal D-pad. It’s very customizable, too, thanks to its accompanying software — something the KK3 Max lacks.

The KK3 Max has a simple and conventional design, replicating the form and layout of the best Xbox controllers. This is no bad thing, though, since such gamepads are among the most ergonomic and comfortable out there. Along with many others, I’m also particularly fond of the asymmetric analog sticks, since this moves the D-pad to a position that makes it easier to use with either thumb.
What may prove more divisive, however, is the relatively small size of the entire unit. I don’t have particularly large hands, but both my thumbs and forefingers tended to overhang the sticks and triggers respectively. I was able to adjust my grip to compensate without sacrificing comfort or security, but others might find this more of a problem.
There are some extra touches to the KK3 Max’s design that set it apart from the crowd. The brilliant white matte finish of my review unit is quite eye-catching, as is the subtle yet effective RGB lighting around the sticks, which also has a practical function that I’ll come to later.
The front plate is incredibly smooth to the touch, smoother than any other controller I’ve experienced. However, this plate isn’t magnetically attached as it is on other gamepads, allowing for easy removal for the sake of customization and reordering or replacing buttons.
You can still remove the KK3 Max’s face buttons — you’ll just need to use the included puller to do so, which is thankfully easy to use. You can’t directly swap the X with the Y button or the A with the B, though, since they have different depths and curvatures. Rather, duplicates of each button are included in the box with the appropriate depth and curvature for swapping their position. This seems like a rather inefficient solution to me, and just means you have more bits of plastic in your life than you otherwise would.
I can’t complain about their quality, though. They’re pleasantly smooth and stable, with only a marginal amount of play, while their transparent design is quite fetching. The D-pad also feels stable, although it’s a shame you can't replace the hat, as different designs can make a real difference to feel and performance, and would cater to more preferences. Fortunately, I found it quite ergonomic; even though it adopts the traditional four-point shape, its rounded edges make it better for rolling between directions.
The triggers are also comfortable. They have rounded outside edges, which makes them soft on the finger, as well as a dotted texture to provide grip. The analog stick caps are reasonably small but have an ergonomic shape and a soft finish. Their edges are slightly textured, although this is less prominent than other examples, so those with sweaty thumbs might slip off them. They are removable, but GuliKit doesn’t provide any extra sets in the box, which is a shame. The sticks themselves are quite tall and suitably planted, with a negligible amount of play.
More solid are the back button levers. Despite how they look, they’re not made from metal, but they are reassuringly sturdy. They actually require a fair amount of force to insert in their slots, but once in place, I felt pretty confident that they weren’t going to come loose. They come in different shapes, with two sets of paddle-like levers and a set that looks more like bumpers.
There’s no software for customizing the inputs of the KK3 Max, which is a shame. However, there are still plenty of adjustments you can make and features to enable using various button combinations. You can alter the sensitivity of the analog sticks, with three levels to choose from, as well as toggle Dead Zone mode for them. You can also enable the Motion Aim Assist mode, letting you assign gyroscopic controls when either the left stick or the left trigger is held. Again, there are three levels of sensitivity to choose from here.
Other settings include a toggle for the D-pad between four- and eight-direction modes, A and B and X and Y swaps, and a Rapid Trigger function with two modes to choose from: one where the chosen input triggers repeatedly when held, and the other when it’s merely pressed. An autopilot mode and a macro recorder are available, too.
All these adjustments are quite easy to make, and there are some useful indicators that let you know what settings have been selected. For instance, the sticks light different colors depending on which of the three sensitivity levels is set, and the pad rumbles once, twice, or thrice depending on which of the three sensitivities of the Motion Aim Assist is set. However, I still would’ve preferred software for convenience's sake; it’s always nice to see your settings represented graphically, and having to remember all the button combinations is a hassle I could do without.
In action, the KK3 Max acquits itself rather well. The face buttons are tactile and well-damped, and only require a light touch to press, which makes them feel snappy. However, they don’t provide the best feedback, and there are times when it can be difficult to feel them actually being pressed. Thankfully, however, this didn’t result in presses failing to register, in my experience.
The bumpers are more clicky, but still have enough dampening to make presses satisfying. However, I found their position a little too high, which can make reaching them a little difficult. I should say that I encounter this problem on quite a few gamepads, but here it’s particularly acute.
In fact, I found the back buttons more usable than the bumpers, which isn’t something I can say about a lot of other controllers with back buttons. Their travel might be shallow, no matter which lever you decide to attach, but there’s enough dampening and feedback to make them viable as replacements for other inputs. I didn’t accidentally trigger them when gripping the KK3 Max tightly, either. The shapes of the various levers are easy to use, although I did find that the lower paddles were best used with two fingers rather than one.
The triggers are resistant enough to provide adequate control when performing graduated presses, something I especially appreciate when playing racing games such as Assetto Corsa that require precise acceleration and braking inputs. Their relatively shallow travel does negate this aspect somewhat, but I still found them just about up to the task. They’re also light enough to perform rapid inputs when needed, and to prevent fatigue from setting in during prolonged holds.
The sticks move freely and quickly, with a fast rebound that makes them feel snappy. Aiming was quite accurate when I played 007 First Light, although they don’t offer the smoothest motion, with small but frequent jumps and unexpected accelerations affecting my accuracy. Thankfully, their aforementioned height didn’t pose a problem when moving them around, although it did cause some instability when pressing in the L3 and R3 buttons, with accidental directional movements often accompanying them.
The gyroscopic motion controls are mixed in terms of their performance. When I played The Legend of Zelda: Tears of the Kingdom on my Switch, they were smooth when aiming the bow, and on a par with the best Nintendo Switch controllers. However, with games on other platforms, such as First Light on PC and Hitman Blood Money — Reprisal on Android, they were jerky and restrictive in terms of movement. No matter how many times I recalibrated them using the onboard function to do this, they didn’t improve on these systems.
I had no issues connecting the KK3 Max to my Windows 11 PC, Switch, or Android tablet via Bluetooth or the USB dongle. The handy button for hot-switching between devices is also useful, and hot-switching itself proved quick in my experience. However, the button doesn’t operate that well, taking a few too many presses to actually respond.
You want a comfortable gamepad
The ergonomic shape of the KK3 Max, combined with the super smooth front panel and rounded triggers, make it comfortable to use — although those with particularly large hands might struggle with it.
You want plenty of back buttons
With four back buttons and three different kinds of lever attachments for them, the KK3 Max is great for those who like to trigger inputs with their fingers rather than their thumbs.
You want software
Even though you can customize the inputs of the KK3 Max, you’ll need to do this with button combinations, as there’s no companion app.
You want the best stick performance
The sticks aren’t quite as smooth or precise as those in the best gamepads.

Valve Steam Controller (2026)
Valve’s latest iteration of the Steam Controller was highly anticipated, and in our view it didn’t disappoint. We found it offered great all-round performance, thanks to its TMR analog sticks and excellent gyro controls. Unlike other controllers, it also features touchpads for controlling cursor movement, making it a real boon for PC players. It doesn’t have the wide-ranging platform support of others, though.
Read our full Valve Steam Controller (2026) review.
8BitDo Pro 3
If you want to spend less on a controller but still want great performance, look no further than the 8BitDo Pro 3. We loved the performance of its sticks, triggers, and D-pad, and we found its shape supremely comfortable, while still staying faithful to the old SNES gamepad it’s keen to emulate. It also has great software with plenty of customizations.
Read our full 8BitDo Pro 3 review.
I tested the Gulikit KK3 Max for a few days, during which time I played a number of games on most of the platforms the controller is compatible with. I used it on my Windows 11 PC via the 2.4GHz wireless USB dongle, and on my Switch and Samsung Galaxy Tab S11 tablet via Bluetooth.
I made sure to play a variety of games across these platforms to test every facet of the controller’s performance. I played 007 First Light on PC, which is a good test for the accuracy and precision of analog sticks, as well as Hitman: Blood Money — Reprisal on my tablet for the same purpose. I also played Assetto Corsa, which is not only a good test for the sticks but also for the control offered by the triggers. I also played The Legend of Zelda: Tears of the Kingdom on Switch, primarily to test the motion controls, as the game and console handle such controls very well.
I’ve been gaming for decades, and have used numerous gamepads with numerous systems in that time. I’ve also reviewed a number of other controllers, from budget offerings to high-performing premium models.

Lasers are no longer required to produce quantum entanglement, physicists say, after achieving the state using sunlight. In a laboratory experiment, an international team of researchers demonstrated that natural sunlight can produce quantum-entangled photon pairs.
The researchers recently published their quantum entanglement study in Optica, showing that lasers aren’t the only game in town. The work could herald a new energy-efficient approach to sustainable quantum technologies, both on Earth and in space.
Quantum technologies such as computing, communications, and sensing rely on the strange principles of quantum mechanics, which often defy explanations rooted in classical physics. Typically, quantum technologies use lasers to convert photons inside a nonlinear crystal into entangled pairs through a process called spontaneous parametric down-conversion (SPDC).
Prior to this work, using sunlight to produce quantum entanglement in photons was largely considered impractical. Researchers had assumed that SPDC depended heavily on phase-stable electromagnetic fields, requiring the high coherence of laser beams. Scientists also believed that the intense power of lasers was crucial to the nonlinear processes that produce entanglement. By contrast, sunlight’s relative weakness and incoherence left it largely overlooked as a viable source for generating entangled photons.
Earlier work may have dismissed sunlight too readily because scientists had not fully considered the different dimensions of coherence. Across different parameters, sunlight can exhibit varying degrees of coherence. This means that while a beam of sunlight may be coherent in a particular property, such as polarization, it can still generate quantum entanglement along that parameter.
“As long as the pump beam is perfectly polarized, its spatial or temporal incoherence should not preclude the generation of polarization entanglement,” said lead author Cheng Li in a statement.
“The trick to harnessing sunlight is to keep different degrees of freedom of light from influencing each other during the process,” Li added. “This means that sunlight is perfectly capable of generating entangled photons, as long as one can concentrate enough sunlight into a nonlinear crystal to induce SPDC.”
In a natural environment, sunlight spreads across a broad area rather than remaining tightly focused like a laser beam. Efficiently directing it through a nonlinear optical crystal, only a few millimeters wide, therefore presents a significant challenge.
To overcome this obstacle, the researchers constructed a sunlight concentration system that collects light across a 1.4-square-meter surface and focuses it down to approximately the width of a human hair. The specialized solar concentrator is conical rather than flat and is constructed from glass. As sunlight reflects repeatedly across the interior surface on its way toward the cone’s tip, it becomes progressively concentrated and intensified before traveling through a single optical fiber to drive the SPDC process that generates quantum entanglement.
In laboratory tests, the researchers found that their sunlight-driven SPDC system produced performance comparable to that of a laser, achieving 94% fidelity. The efficiency of the entanglement process was also similar to that achieved with laser-based systems. Together, these findings challenge previous assumptions that SPDC requires highly coherent laser light to operate effectively.
The approach also eliminates the need to first convert electrical energy into optical energy, potentially reducing system complexity, heat generation, and points of failure.
“Sunlight is an abundant and reliable resource in many environments, especially in space. Being able to generate quantum-entangled photons directly from sunlight could enable simpler and more resilient quantum systems for satellites and future deep-space missions,” said Hanieh Fattahi, the study’s co-author, in a statement.
“We believe this work can inspire much new research in nonlinear and quantum optics,” Fattahi said, adding that this research “may in turn make sunlight-driven quantum technology more practical.”
The paper, “Generating Quantum Entanglement from Sunlight,” appeared in Science Advances on August 5, 2026.
