Although no one has officially stated it, 2025 has certainly been an exceptional year for comets. There’s Comet Lemon, discovered in January and making headlines for nine months. Each time I encountered that striking long tail formed by the comet’s solar heat, I was captivated.
In September, C/2025 R2 (SWAN) was discovered, radiantly bright even when near the moon on Halloween, making it easily visible. Then came Comet 3I/Atlas, which gained notoriety after a Harvard astronomer—primarily a cosmologist—identified it as an alien probe.
As a cosmologist who recognizes my limited expertise in comet studies, I fully trust the specialists asserting that Comet 3I/Atlas is not some extraterrestrial object. This isn’t a regret; this comet is still scientifically intriguing. Unlike lemons and SWANs, it hails from beyond our solar system, categorizing Comet 3I/Atlas as an interstellar comet.
Its entry into our solar system offers a thrilling opportunity. While pinpointing its exact trajectory may be unattainable, its composition can reveal a wealth of information about its parent star. Essentially, we can learn about the makeup of an enigmatic star even when its identity remains unknown.
Our expedition with this year’s comet reflects a long historical pattern of human fascination with enigmatic celestial phenomena. Most notably, Halley’s Comet’s passage in 1066 was illustrated in the Bayeux Tapestry, symbolizing the onset of the Norman invasion of England. Nowadays, we understand that humanity is not the universe’s focal point, and the universe lacks a center—but it’s easy to entertain the notion that the comet of 2025 could be conveying a message.
Reflecting on this year, filled with distressing and unfortunate occurrences, it’s tempting to ponder whether these comets hint at an impending apocalypse. The state of science in the United States faces turmoil, as the current administration cuts funding and initiatives (see page 20). Moreover, anti-immigrant sentiments have gained a mainstream foothold in both the United States and the United Kingdom.
As a Black and Jewish queer scientist, and an immigrant’s child, maintaining an open heart daily is a struggle. I recognize that there are those who wish to silence me. Contrary to my previous scientific education, I could interpret the comet as a sign to surrender. Yet, alternative paths exist. As a scientist, I perceive comets as sources of hope. They are breathtaking visual havens. The quest to observe them has fostered community. My astrophotography group eagerly anticipates sharing our experiences. While it’s frustrating to encounter rampant misinformation in various media concerning questions like “Are they aliens?”, I feel grateful that attention is being drawn to these phenomena.
For 2026, my aspirations are immense. Scientifically, I yearn for groundbreaking observations of dark matter. Socially, I aim to ensure that all children have access to essential resources—food, shelter, education, and healthcare—in environments that affirm their identities. While these are monumental dreams, they likely won’t manifest by year’s end. Nevertheless, comets remind us of the vast universe, brimming with marvelous surprises. Just as we strive to discover comets, we must also endeavor to create the better world we desire.
TThe ROG Xbox Ally X, a handheld console resulting from a partnership between Asus and Microsoft, stands out as an impressive yet costly gaming device. The sleek all-black ROG Xbox Ally X, set to launch on October 16th, is the pricier of the two portable gaming options at £799 (€899/$999/AU$1599). (In comparison, the less powerful ROG Xbox Ally in white is priced at £499/€599/$599/AU$999.) Fortunately, the higher price tag brings with it enhanced features and performance.
Over the past few weeks, I’ve been enjoying the ROG Xbox Ally X while navigating through various indie hits and major RPGs throughout my home. Although its price is quite eye-catching (consider that its main rival, the Steam Deck OLED, starts at £479/€569/$549/AU$899), the power contained within its compact dimensions (291 x 122 x 51 mm) is truly unparalleled in the portable gaming sector.
This remarkable power, combined with the capability to stream Xbox titles via cloud gaming and the Play Anywhere initiative (interconnecting purchases between Xbox and PC), allows access to a diverse array of PC games from various storefronts, appealing to both Xbox enthusiasts and portable gaming fans. While I encountered a few minor glitches and user interface hiccups during my time with the ROG Xbox Ally X, most were easily rectifiable and quickly became forgotten as I immersed myself in gameplay.

Setting up ROG Xbox Ally X
Configuring the ROG Xbox Ally X is a straightforward task. The device launches a full-screen Xbox experience that replicates both the Xbox console and PC app environments; however, as a handheld operating on Windows 11, it requires an initial update before usage, which took a bit of time. This might feel unusual for a gaming handheld, given the pop-up notifications and prompts typical of a standard Windows setup.
On the first day, despite promptly adding my Xbox account, the device indicated that I lacked Xbox Game Pass Ultimate, Microsoft’s highest-tier gaming subscription service, and my efforts to relink the account proved fruitless. Strangely, it randomly began functioning correctly the next day. I also faced issues connecting to my home Wi-Fi upon waking the device from sleep mode, yet this too rectified itself after the first 24 hours.
Once I successfully connected my various accounts (the ability to download PC game launchers like Steam, Epic Games Store, and Blizzard’s Battle.net is a benefit of being a Windows handheld), the ROG Xbox Ally X operated quite efficiently.
A handy feature allows direct access to the familiar Xbox user interface while aggregating games from other launchers for seamless transitions back to your gameplay, regardless of where it’s hosted.
However, should you be playing a Steam game, switching back to the Xbox-only launcher and starting a game from a different store requires taking note that ROG Xbox Ally X does not automatically close the previously opened game, nor does it ask if you wish to do so, which can affect performance. There were instances when the Xbox interface lagged or became unresponsive to my inputs.
At times, the handheld experienced difficulties downloading an RPG, repeatedly disconnecting whenever idle, necessitating a manual restart of the process. Nevertheless, subsequent to rebooting, the remaining files downloaded successfully.

ROG Xbox Ally performance
I remain hopeful that these issues can be addressed with a simple user interface (UI) update. With a bit of attention, the ROG Xbox Ally X demonstrates exceptional performance. Although it shows some sluggishness when starting up with a low battery level (below 15%), titles like Hades II, Supergiant Games’ acclaimed roguelike sequel, load quickly and run flawlessly with negligible load times between areas. Heavier games like Avowed and traditional PC favorites such as Backyard Baseball maintain outstanding performance with impressive frame rates and rapid load times.
While the ROG Xbox Ally X lacks an OLED screen, the 7-inch, 1080p display more than compensates with stunning visuals. The vibrant details of Hades II’s nearly stationary characters are a visual delight. The first time Moon Goddess Selene appeared adorned in a luminous gown of blue and seafoam green, it was a breathtaking moment.
Xbox and Asus have strategically allocated some system resources for heightened frame rates, a decision that pays off in visually demanding games like Hades II. You’ll never be left so overwhelmed by the action that you lose track of the battle at hand.
The audio experience is equally immersive. In a particular sequence in Hades II, as I strolled past the goddess Artemis in a moonlit glade, I could hear her singing softly from the left speaker, signifying her presence even when out of view—such lovely details truly stand out.
Regarding its appearance, the ROG Xbox Ally X may initially seem peculiar, resembling two halves of an Xbox controller fused with a screen, yet the matte black finish is visually attractive, and the adjustable LED lights accentuating the joysticks add to the gaming aesthetic.

Game on the go or on the couch
Throughout my experience with the ROG Xbox Ally X, I’ve utilized it while lying in bed, relaxing on the couch, leaning against the kitchen counter waiting for pasta water to boil, and sitting at my desk during writing breaks. Initially, after just 10 minutes of use this summer, I questioned whether the relatively large handheld would be comfortable for extended sessions. Surprisingly, it remained comfortable to hold even after hours of gameplay. Although weighing in at 715g, it is heavier than the less powerful ROG Xbox Ally (670g) and Steam Deck OLED (640g), the difference in weight is minor, especially given how ergonomic the controller-like grips are. The only discomfort arose when I propped it against the couch without any elbow or wrist support, which caused some strain on my pinky finger due to bearing the weight.
The battery life is commendable considering the specifications (80Wh, surpassing the ROG Xbox Ally’s 60Wh). I was able to play Hades II for a solid two hours without hitches. After 20 minutes of gameplay at 22% battery, it only dropped to 10%. Although some components of the handheld warmed up during extended play, it never reached a point of overheating.
In terms of gaming, this device ingeniously utilizes the Xbox Play Anywhere initiative. This reflects Microsoft’s efforts to enable access to games across multiple devices, allowing gameplay on PC, Xbox consoles, and the ROG Xbox Ally handheld, all while retaining your progress, with access to over 1,000 available Xbox and Xbox Game Pass games.
Having formerly owned a Steam Deck and been a long-term Xbox Game Pass subscriber, the ROG Xbox Ally X represents the ideal handheld console for me. I favor the feel of an Xbox controller, and this device captures that essence perfectly. It allows me to access my Xbox Game Pass library to experiment with new titles, all while offering portability. Plus, for Play Anywhere titles, which a majority of the games are, there’s no need to stress over internet access.
If you have the budget and seek a robust gaming handheld capable of not only playing PC games from your favorite digital platform but also an extensive selection of Xbox games, the ROG Xbox Ally X could be an excellent investment for the year-end splurge.
As the UK is currently experiencing another intense heatwave, many are questioning why the high temperatures feel particularly unbearable compared to other parts of the world.
Despite facing the same scorching sun and global warming trends, the heat in the UK seems to have a unique impact, leading some to wonder if there are other factors at play beyond just the temperature on the thermometer.
With temperatures reaching around 30°C, the British heatwave seems extreme when compared to climate change-induced wildfires in the US and Europe.
Before dismissing this as a common British complaint, it’s important to acknowledge that scientific evidence proves the severity of the heatwave in the UK.
“Heatwaves are subjective events, with different countries interpreting them based on people’s average expectations,” explained climate expert Professor Hannah Croke in an interview with BBC Science Focus.
Professor Croke emphasized that factors like humidity, wind speed, and temperature all play a role in how a heatwave is experienced and perceived by individuals.
Something is floating in the air
The UK’s island geography means that it is surrounded by water, which leads many to assume it would help cool down the country. However, the presence of cold water can actually have the opposite effect.
Meteorologists like Dr. Matthew Patterson explain that the UK’s climate, influenced by moist marine air, affects how heat is lost from the body through radiation, conduction, convection, and evaporation.
Evaporation plays a key role in cooling the body, but high moisture levels in the air can decrease its effectiveness. Wind speed also impacts evaporation, with strong winds aiding in cooling the body.
Indices like Feels Like Temperature and the Universal Temperature Index (UTCI) are used to predict how temperature, humidity, and wind speed will affect individuals during a heatwave.
UK homes not fit for purpose
The design of UK homes, coupled with the lack of standard air conditioning, poses a challenge during heatwaves. The majority of UK homes are not equipped to deal with extreme heat due to their design and age.
Historically, UK homes were built to allow sunlight in, which can lead to higher indoor temperatures. In contrast, European and American homes often have external shutters to block out heat.
As temperatures continue to rise due to climate change, the design and construction of UK homes will need to adapt to better cope with heatwaves. Lack of understanding on how to keep homes cool during hot weather exacerbates the issue.

○On Sunday, January 22, 1984, the Los Angeles Raiders defeated the Washington Redskins 38-9 in Super Bowl XVIII. With the exception of a few older Raiders fans, we all remember him that night 40 years ago with one ad that set the tone for the techno-optimism that would dominate the 21st century. did.
Advertisement showed an auditorium full of zombie-like figures watching a projection of an elderly leader resembling the Emperor from 1980's The Empire Strikes Back. A young, athletic woman wearing red and white (the colors of the flag of Poland, which waged a massive labor uprising against the Soviet-controlled communist state) spins a hammer and frames the face of her leader. He threw it across the screen. As armored police rush in to stop her.
The ad explicitly referenced George Orwell's dystopian novel 1984. Meanwhile, then-President Ronald Reagan began his re-election campaign with the audacity to confront the threat of the totalitarian Soviet Union, increasing the risk of global nuclear annihilation.
That same month, Apple began selling personal computers. This will change the way we think about computing technology in our lives and will lead to many of the ideological changes that will drive the 21st century. In many ways, the long 21st century began 40 years ago this week for him.
From a garage-based startup in Cupertino, California, we have steadily grown to where we are today. The most valuable company in the history of the world, Apple has changed the way we experience culture and each other. While not the only force to do so, if you look at other ruling forces that left their mark in 1984, such as Reagan, Apple is a key player in how we view and govern ourselves over the next 40 years. It was part of a larger change. Years later, it still impacts daily life in ways few could have imagined at the time.
Before the Macintosh debuted, Apple created high-quality computers like the Apple II (1979) that ran programs using the standard operating system at the time, the Apple Disc Operating System (which was similar to the Apple Disc Operating System). was highly regarded among computer enthusiasts for producing innovative desktop computers. MS-DOS was provided by a small then-starting company called Microsoft and could be programmed in languages such as Basic.
Companies like Texas Instruments and Atari had brought user-friendly computers to homes before the Macintosh, and IBM and Commodore had made desktop computers for businesses, but the Macintosh was something different. I was promised something.
The Macintosh created a mass market for usable computers that looked more like magic than machines. The Macintosh is a sealed box that hides the board and cables and presents a sleekly designed box, similar to the MacBook and the iPhone, which was released in 2007 and was the most influential and profitable of Apple's products. We have established design standards for what will become.
The iPhone represents much of what's appealing and loathsome about 21st century life. This is a device that does things that no other device or technology can do. It just provides all of that in its own controlled environment that masks all of the actual technology and the human agency that created it. There may be a little elf in there.
Billions of people now use such equipment, but few people ever look inside or think about the people who mined the metals and assembled the parts in dangerous conditions. plug. There are now cars and appliances designed to feel like an iPhone, all glass, metal, curves, and icons. None of them provide any clues for humans to build or maintain them. Everything seems like magic.
The shift to magic by design has blinded us to the real situation of most people working and living in the world. Gated devices are similar to gated communities. What's more, the sealed boxes are equipped with ubiquitous cameras and location devices, and when connected through invisible radio signals, serve as a global surveillance system that Soviet dictators never dreamed of. . We have also entered a world of soft control beyond Orwell's imagination.
Gated communities began to grow in popularity in the United States during the Reagan administration. It was to provide the illusion of safety against imagined but undefined invaders. They also resembled private states, with exclusive membership and strict rules of etiquette.
Reagan won reelection in a landslide in the November 1984 election. His Reagan victory established a nearly unwavering commitment to market fundamentalism and technological optimism that was largely adopted by Reagan's critics and even his successors like Bill Clinton and Barack Obama. . Outside the United States, ostensibly left-wing 20th century leaders such as Greece's Andreas Papandreou, France's François Mitterrand, and Britain's Tony Blair limited the vision of change that the growing neoliberal consensus allowed. was.
By the beginning of this century, questioning the techno-optimism imposed by Apple and the faith in neoliberalism secured by Reagan's hold on the world's political imagination seems like a fit of sulking or sulking. Probably. Does anyone doubt the democratizing and liberating potential of computer technology and free markets?
Now, a quarter of the way through this century, it's clear that the only promises kept were to Apple's shareholders and the descendants of Reagan's politicians. Democracy is in tatters around the world. Networked computers rob relationships, communities, and society of the joy and humanity. The economy is more stratified than ever before. Politics excludes any positive vision of a better future.
Of course, you can't blame Apple or Reagan. They simply distilled, harnessed, and sold back to us what we longed for: a simple story of inevitable progress and liberation. If we had heeded the warnings in Orwell's book instead of Apple's ads, we might have learned that simple stories never have happy endings.
