Dark matter makes up over 25% of the universe’s mass, holds galaxies together, and is essential to our understanding of cosmic structure. It doesn’t interact with light or other electromagnetic radiation, and is detectable only through its gravitational effects. While astrophysical and cosmological evidence confirms its presence, its true nature remains one of the greatest mysteries in modern physics.

A leading theory suggests that dark matter consists of extremely light, elusive particles called axions. Traditional axion searches rely on narrow-band resonance techniques, which require slow, step-by-step scanning across possible axion masses, making the process time-consuming.

In this study, researchers introduce a new broadband quantum sensing approach using an alkali-²¹Ne spin system, which works like a very sensitive antenna to listen for signals from dark matter. They identify two distinct ways the system behaves under different conditions. At low frequencies, the spin system naturally adjusts itself to cancel out noise or unwanted effects. This self-compensation makes the system stable and sensitive, even without fine-tuning. It’s like a car that automatically balances itself on a bumpy road, you don’t need to steer constantly. At higher frequencies, the system enters a state where the spins of different atoms resonate together. This resonance boosts the signal, making it easier to detect tiny effects caused by dark matter. Like two musical instruments playing in harmony, the combined sound is louder and clearer. This allows researchers to significantly expand the search bandwidth without sacrificing sensitivity.

Their experiment covers a vast frequency range, from very slow oscillations (0.01 Hz) to very fast ones (1000 Hz), enabling a comprehensive search for axion-like dark matter. They set new constraints on how axions might interact with neutrons and protons. For neutrons, they reached a sensitivity that beats previous astrophysical limits in some frequency ranges. For protons, they achieved the best lab-based constraints in specific frequency bands.

This work not only advances the search for dark matter but also opens new frontiers in atomic physics, quantum sensing, and particle physics, offering a powerful new strategy to explore the invisible fabric of the universe.

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the mathematical symmetries: general relativity uses infinite-dimensional space-time symmetries, while the Standard Model relies on compact, finite-dimensional ones, making the two frameworks fundamentally incompatible.

A central question in this context is: is gravity a force? Newtonian mechanics says yes, gravity pulls masses together. Einstein’s relativity says no, it’s the curvature of space-time that guides motion. Quantum field theory suggests gravity may be a force mediated by hypothetical particles called gravitons.

The researchers behind this work propose that gravity can be treated as a gauge interaction, similar to electromagnetism. This approach implies gravity is a force mediated by a field and governed by the same kinds of symmetries as the other fundamental interactions.

They introduce unified gravity, a novel framework that reformulates gravity using the compact symmetries of quantum field theory. Working with an eight-dimensional spinor model, they define a space-time dimension field to recover familiar four-dimensional space-time. By applying four U(1) symmetries, they derive a gauge theory of gravity that mirrors the Standard Model, with the stress-energy-momentum tensor emerging naturally from these symmetries.

Their theory reproduces teleparallel gravity through a special geometric condition and describes gravity in flat Minkowski space-time by another geometric condition, making it compatible with quantum field theory. They develop Feynman rules and show the theory is renormalizable at 1-loop, meaning it handles quantum corrections without mathematical breakdown. Finally, they demonstrate that the theory respects BRST symmetry, which ensures gauge consistency in quantum field theory.

While this remains a mathematical theory, it prompts us to reassess how we conceptualize gravity, not as a curvature of space-time, but as a gauge interaction like the other fundamental forces. If validated experimentally, unified gravity could reshape our understanding of the universe and mark a major turning point in theoretical physics.

Everyone needs contact comfort sometimes. Not everyone has ample opportunities for this in facetime. So here is a chance for a cuddle party in cyberspace. Virtual cuddling can help people feel better.

We have a cuddle room that comes with fort cushions, fort frames, sheets for draping, and a weighted blanket. A nest full of colorful egg pillows sits in one corner. There is a basket of grooming brushes, hairbrushes, and styling combs. A bin holds textured pillows. There is a big basket of craft supplies along with art markers, coloring pages, and blank paper. The kitchen has a popcorn machine. Labels are available to mark dietary needs, recipe ingredients, and level of spiciness. Here is the bathroom, open to everyone. There is a lawn tent and an outdoor hot tub. Bathers should post a sign for nude or clothed activity. Come snuggle up!

Let's begin with an academic paper exploring the way that online puppygirl culture embodies a rejection of those things used as markers of human success because of the way that the highly transfeminine nature of puppygirls are usually denied the full markers of humanity based on their transness. The author notes at the end the limitations around embracing inhumanity for persons who have been and continue to be treated as inhuman based on their skin colors and perceived origins, and that the relative homogeneity of participants in online puppygirl culture and media often gives them blinkers in places they could stand to be more inclusive. I enjoyed reading it, perhaps you will, too.

The still-apparently-novel concept that people who have systems tuned toward novelty and curiosity might be beneficial to current society (instead of only the hunter-gatherers) and that environments made for others are not helpful to them.

The Archive of Our Own reminds us that they are dealing with an influx of spam accounts that leave generic praise comments and then offer to discuss off-site things like making fanart for your story. Part of it is that such commercial solicitation is barred on the Archive, but the easiest way to spot it, other than the invitation offsite, is that the comment itself doesn't have anything specific about the story. It's usually posted to the most recent story that's available. And some of these spammers are creating AO3 accounts to spam with, so disabling guest comments won't necessarily protect you from receiving them.

Nostalgia for times where scarcity required planning and people got a certain thrill out of the act of chasing things and not knowing whether their selections would turn out to be good ones. I am more inclined not to be nostalgic for that, but to be annoyed at the way that the expertise of the record clerk, the librarian, and the bookstore buyer are being devalued in favor of machines that their promoters claim have intelligence and can do all of those things a human can do, and better.

Robert Redford, actor, director, and well-known environmental activist, has left the world at 89 years of age. He is also responsible for the body that produces the annual Sundance Film Festival.

Anonymous art creators have unveiled a statue of the current administrator and known child trafficker and pederast Jeffrey Epstein holding hands, celebrating their friendship, and using the text of the administrator's birthday note to Epstein as commentary. You know, that text that strongly suggests that the two of them share an interest in pederasty and molestation of women and young girls, buttressed by some of the public statements the administrator has made about his interest in such. (As well as having been found liable for sexual assault earlier on in his life.)

( EA acquisitions, foolishness and buffoonery, and the usual issues that come with having the unqualified promoted well beyond their incompetence inside )

Last out, the ways in which our understanding of classical Greek depends on the surviving texts that we have to work with, and therefore while sometimes a word does mean dildo, other times, it does not.

Yacht Club Games on the development of modes for Shovel Knight that allow for different-bodied designs and pronoun usage, and a good decision made by them to decouple body designs and gendered pronouns.

And a story of corvids who help break the cages around their fellows. Be gay, do crow. And, perhaps, show solidarity by demonstrating how foolish it is to require girls to declare they're "biological females" before they can play in sort. (While the article quotes someone saying it's foolish not only require girls to do this and not boys, and that girls teams are suffering because they can't field enough affirmed players, the real meat is from the teachers saying it's not fair to require this, and the athletes who are also choosing not to participate because of fairness issues.)

Long commutes and small homes are wrecking sleep

Your commute and home size could be quietly stealing your sleep.

Tokyo residents face a trade-off between home size and commute time when it comes to sleep health. A new study shows longer commutes increase both insomnia and daytime sleepiness, while smaller housing also raises insomnia risk. Even with average-sized homes, commuting more than 52 minutes pushed people into the insomnia range. Researchers say smarter housing planning could improve both sleep and quality of life.

It occurred to me the other day that since the SAD-fighting daylight lamp I have is pretty old now, it still has a big light bulb in it that gets really hot even in the short amounts of time it's supposed to be used. And I'm not as poor as I used to be so I could get a new one.

As always when I need to purchase anything, I asked V for help because they're very good at this. They suggested I might want to try one of those sunrise alarm clocks too. Which I'd never thought about because I'm not really an alarm kind of person a lot of the time, thanks to sleep-maintenance insomnia. But when they sent me a link to what they found and I saw it does a "sunset" thing where you can have gradually-diminishing light and sounds to put on at bedtime, I thought that might be worth a try. I've had increasing trouble settling down to sleep in recent months, and I don't love the workarounds I've resorted to.

Both arrived today, so I write this with orangey light and nature sounds next to me, and the daylight lamp set up by my desk downstairs waiting for me in the morning. We'll see how they work.

https://physicsworld.com/?p=124209

Leo Cancer Care is a trans-Atlantic company that’s pioneering the development of upright radiotherapy – a totally new take on radiation delivery in which the patient is treated in an upright position and rotated in front of a fixed treatment beam. At this week’s ASTRO 2025 meeting in San Francisco, the company introduced its first upright photon therapy system, named Grace, to an enthusiastic crowd in the ASTRO exhibit hall.

Upright treatments have a host of potential advantages over conventional radiotherapy, where patients typically lie on their back during treatment. Studies have shown that the more natural upright posture could deliver more consistent anatomical positioning and organ stability, as well as enabling more comfortable treatment positions, with patients who have experienced the technology reporting improved comfort and greater patient–therapist connection.

A fixed treatment beam also simplifies system design, reduces space and shielding requirements, and lowers infrastructure costs. And for proton therapy in particular, removing the need for a bulky and expensive gantry could help increase global access to advanced cancer treatments. Indeed, a partnership between Leo Cancer Care and Mevion Medical Systems led to the development of the MEVION S250-FIT, an ultracompact upright proton therapy system that fits inside a linac vault.

Moving on from Leo Cancer Care’s initial focus on proton therapy, the new Grace system will deliver conventional X-ray radiation therapy with patients positioned upright. Grace – named after American computer scientist and US Navy rear admiral Grace Hopper – comprises an upright patient positioning system (with six degrees of freedom and 360° continuous rotation) in front of a stationary 6 MV photon linac.

“Our future innovation, Grace, will take a proven technology, photon therapy, and rethink the way it can be delivered,” Sophie Towe, the company’s director of marketing, tells Physics World. “Upright treatment isn’t just about comfort; it’s about consistency, stability and ultimately accessibility. By integrating advanced CT imaging, faster beam delivery and a more natural patient position, we are opening the door to more adaptive and affordable care. Our goal is to show that innovation in radiotherapy doesn’t always mean bigger or more complex; it can mean smarter and more human.”

The system features a fan-beam CT scanner at the treatment isocentre, enabling planning-quality imaging throughout the entire treatment workflow. It also incorporates a large, ultrafast multileaf collimator that, in combination with the stationary photon beam delivery system, is designed to optimize dose conformity and treatment efficiency.

“Leo Cancer Care is already known for delivering upright particle therapy technology, and over the past few years we have seen a real paradigm shift as a result,” says co-founder and CEO Stephen Towe in a press statement. “Grace represents a return to our original company focus of delivering more cost-effective photon treatments to a global stage without sacrificing on treatment quality. Our technology has always been bold, but we are pioneering with purpose and that purpose is to put the patient truly back at the centre of their treatments.”

The company will install the first pre-commercial Grace systems at healthcare institutions within the Upright Photon Alliance research collaboration, which include Centre Léon Bérard, Cone Health, IHH Healthcare, Mayo Clinic and OncoRay.

I mostly post about: tennis, fannish rambles, book reviews, occasional football nostalgia, and random life musings
My hobbies are: reading (historical fiction, romance + the occasional sports biography), writing emotionally messy fanfic, cozy farming sims (stardew valley hours are ridiculous), traveling when i can, and yelling fondly at tennis players and footballers
My fandoms are: tennis (lifelong), historical fiction nerdery, bridgerton, and a splash of nostalgic 90s/00s pop (yes i still love take that and one direction, no regrets)
I'm looking to meet people who: are fannish, bookish, or just like chatting about their passions. bonus points if you also get tennis brainrot or historical-fiction cravings.
My posting schedule tends to be: sporadic — sometimes i post a lot, sometimes i vanish into the void with a book or a video game.
When I add people, my dealbreakers are: no bigotry, no cruelty. fannish disagreements are fine, but being mean about real people (especially athletes/actors etc.) is not my jam.
Before adding me, you should know: i ramble a lot in lowercase, i treat my journal more like a diary/archive than a performance space, and i’m always happy to chat if you are!
