Measuring Quantum Geometrty
MIT physicists have directly measured the quantum geometry of electrons in solids for the first time, unlocking new insights into quantum materials. This breakthrough, achieved with ARPES, could advance quantum computing and materials science by revealing properties previously only theorized.
Work reveals new ways to understand and manipulate electrons in materials.
MIT physicists, in collaboration with colleagues, have measured the geometry—or shape—of electrons in solids at the quantum level for the first time. While scientists have long been able to measure the energies and velocities of electrons in crystalline materials, the quantum geometry of these systems has, until now, remained theoretical or, in some cases, completely elusive.
The work, recently published in Nature Physics, “opens new avenues for understanding and manipulating the quantum properties of materials,” says Riccardo Comin, MIT’s Class of 1947 Career Development Associate Professor of Physics and leader of the work.
“We’ve essentially developed a blueprint for obtaining some completely new information that couldn’t be obtained before,” says Comin, who is also affiliated with MIT’s Materials Research Laboratory and the Research Laboratory of Electronics.

The work could be applied to “any kind of quantum material, not just the one we worked with,” says Mingu Kang, first author of the Nature Physics paper and a Kavli Postdoctoral Fellow at Cornell’s Laboratory of Atomic and Solid State Physics. Kang, MIT PhD 2023, conducted the work as a graduate student at MIT. READ MORE...

How to Photograph Wildlife
I have been wanting to photograph animals that I have been finding recently, like salamanders, snakes, insects, frogs, maybe even a cool plant or two. But I was unsure how to do this well. Most invertebrates and plants will be relatively easy, but animals that are faster to run and hide will be much more difficult, like snakes, lizards, and salamanders. Obviously I would want to avoid handling them (especially salamanders) but what should I do if the animal hides? Lifers and rarer animals I would especially want to photograph, but I also want it to be natural and ethical. I’m not sure how I feel about posing the animal (it feels unnatural and I’m not sure it’s ethical) but would moving the animal to a clearer spot be considered posing? And also, how could I photograph a venomous snake? I would love to find a venomous snake, especially if I can get a good photograph of it, but obviously I can’t handle it so I can’t do much to keep it from running away, and again I don’t want to stress it. Also, how would I be able to do it from a safe distance?
I will be posting these photographs (especially ones of animals with bad reputation) on iNat and the Nextdoor Neighbor app. My goals with the Nextdoor app is to show my community the beautiful animals that they are too often portrayed as evil, dangerous, and disgusting creepy-crawlies and hopefully change some minds.
I am just wondering how others photograph wildlife and how to ethically do so. Any advice appreciated!

Hate
billionaires barf out statements
thought to be in everyday use,
in front of millions... hoping
to change attitudes...
preconceived ideas...
and opinions...
how do billionaires see hate,
many of us wonder.
flying around in private jets
eating croissants in Paris
bagels in the Caribbean
or drinking expresso in Rome...
Hate is what we know...
what we learned from preachers,
manifested in the teachings
of those who came before.
Hate is not for sale or bargained with,
it is what we live with daily,
it's all we know to do with each other.

LIX Super Bowl
I watched the super bowl last night, something that I seldom do... not sure why I did, but I did. Needless to say, I was disappointed with the game but not because the Chiefs did not win.
I was kinda hoping that the Chiefs would set a record and win three in a row because I like to see records set, and not because I support the Chiefs.
I was disappointed because I expect All SUPER BOWLS to be a super match-up between two teams that are equally matched and there is a nail-biter game for both sides...
Like a heart attack level of excitement...
This was not the case...
The CHIEFS were completely OUT MATCHED in every measurable category of the game.
It was not fun to watch, even for the EAGLES fans.
What kind of win is it, when the opposing team is as incompetent in their defense/offense as the Chiefs were?
Is that how one side wants to win?
I am sure there are those who say that a win is a win and to some degree they are correct...

Explore Aging
The biology of aging
Aging is a complex biological process affecting our cells, tissues, and organs. With each passing decade, researchers uncover additional causes and effects of this seemingly unstoppable process. This 13-minute video is a visually stimulating deep dive into every aspect of our current understanding of aging. Watch it here.
Can aging be reversed?
Aging has always been inevitable, but fasting, epigenetic reprogramming, and parabiosis are a few scientific techniques that seem to help people stay young. By studying centenarians, how memory works, and even the humble roundworm, might the Peter Pan dream of eternal youth eventually become a reality? Learn how it might here.
Visualizing the global increase in life expectancy
The human species has experienced a dramatic increase in expected lifespan over the past 150 years. The development of antibiotics, improved sanitation, and better food distribution are just a few of the factors that contributed to this rapid transformation. Use this interactive resource to explore longevity gains over time and across the globe.
The connection between movement and healthspan
Healthspan refers to the number of years one is active and disease-free. The ultimate goal would be to extend one’s healthspan to match one’s lifespan, necessitating a shift in focus toward the pursuit of healthy aging. This article explores the two concepts as well as the critical importance of maintaining activity levels as we age. Read it here.
Inside the expensive race to age the slowest
Created by entrepreneur Bryan Johnson in 2022, the Rejuvenation Olympics asks participants to try to slow their biological aging rate, which they attempt to do through various approaches, such as exercise or dietary supplements. But some of these tactics are extreme in cost or nature—such as Johnson's regular injections of blood from his teenage son.
Why does our appearance change as we get older?
Graying hair, shrinking height, and wrinkles: While most people can list the visible effects of aging, not everyone could explain why these changes occur. We go gray due to the death of pigment cells near our hair, and we shrink due to thinning spinal disks. Read this article for a detailed explanation of the causes behind the physical changes associated with aging.

Damien Steven Hirst (/hɜːrst/; né Brennan; born 7 June 1965) is an English artist and art collector. He was one of the Young British Artists (YBAs) who dominated the art scene in the UK during the 1990s.
Death is a central theme in Hirst's works. He became famous for a series of artworks in which dead animals (including a shark, a sheep, and a cow) are preserved, sometimes having been dissected, in formaldehyde. The best-known of these is The Physical Impossibility of Death in the Mind of Someone Living, a 14-foot (4.3 m) tiger shark immersed in formaldehyde in a clear display case.
