New kinds of matter and magnetism

(via Reddit) ExtremeTech.com reports on the discovery of a new state of matter, Quantum Spin Liquid (QSL), and a new kind of magnetism.

The existence of QSLs has been theorized since 1987, but until now no one has succeeded in actually finding one. In MIT’s case, the researchers spent 10 months growing a tiny sliver of herbertsmithite (pictured above) — a material that was suspected to be a QSL, but which had never been properly investigated. (Bonus points if you can guess who herbertsmithite is named after.) Using neutron scattering [...] the researchers found that the herbertsmithite was indeed a QSL.

Moving forward, Lee says that the discovery of QSLs could lead to advances in data storage [...,] and communications (long-range entanglement). [Young] Lee also seems to think that QSLs could lead us towards higher-temperature superconductors — i.e. materials that superconduct under relatively normal conditions, rather than -200C.

Really, though, the most exciting thing about quantum spin liquids is that they’re completely new, and thus we ultimately have no idea how they might eventually affect our world.

Lately it seems like there's cool new quantum science coming out roughly every week.  More likely, I just notice it more now that the Higgs is found and the spell of ambiguity surrounding quantum physics is broken -- as I wrote on Particle Day earlier this year, "I never really believed they were going to find it.  I had this weird sense of pessimistic determinism about the whole thing, because up to that point, everything about chemistry and physics that was known, as far as I knew, was known long before I was born."

Now, rather than feeling like science is basically cooked, and we're just pushing up against a wall of inscrutability, I feel like our understanding of the universe is exploding forward every day.  It's pretty cool.  And I'm grateful.

NY Times on Innovation

The New York Times posted a cool article a few days ago called "32 Innovations That Will Change Your Tomorrow," outlining what  the writers argue are important innovations that exist now, and will be very important in the future.

When we ignore how innovation actually works, we make it hard to see what’s happening right in front of us today. If you don’t know that the incandescent light was a failure before it was a success, it’s easy to write off some modern energy innovations — like solar panels — because they haven’t hit the big time fast enough.

My favorite parts:

Soon, coffee isn’t going to taste like coffee — at least not the dark, ashy roasts we drink today. Big producers want uniform taste, and a dark roast makes that easy: it evens out flavors and masks flaws. But now the best beans are increasingly being set aside and shipped in vacuum-sealed packs (instead of burlap bags).

I am so looking forward to the future where dark roast coffee isn't a thing anymore.  Dark roast is awful.  People who claim to like dark roast are, mostly, lying, and that crap can't go away soon enough.  (Crappy coffee is a major reason I switched to pills for my caffeine intake.  That, and it's way cheaper.)

The problem with laptops and tablets, says Mark Rolston of the design firm Frog, is that they’re confined by a screen. He wants to turn the entire room into a monitor, where you can have the news on your kitchen table while you place a video call on your fridge. And when you’re done, you can swipe everything away, like Tony Stark in “Iron Man.”

I want this.  That is all.

Wearing a small sensor on your head, at home, while you sleep, could be the key to diagnosing diseases early and assessing overall health. “This tech,” says Dr. Philip Low, the founder of a medical technology firm called NeuroVigil, “enables us to look for faint signals of, say, schizophrenia, Parkinson’s, depression or Alzheimer’s in the brain, even though there may be no obvious symptoms.” [...] Currently, Low is working on a newer version of the device, which will be the size of a quarter and will transmit brain scans directly to smartphones and tablet computers. “We’re using sleep,” Low says, “as the gateway to the brain.”

I suffer from depression, and I fully support any mechanism which allows me to monitor for its onset.  It's not easy to tell you're depressed when you're depressed, and it's even harder to get yourself to do something about it at the time.  I'd love to have a thing to put on my head that would just email my psychiatrist if my mood was dropping in a serious way.  On that topic:

This year, Eva Redei, a professor at Northwestern’s Feinberg School of Medicine, published a paper that identified molecules in the blood that correlated to major depression in a small group of teenagers. Ridge Diagnostics has also started to roll out a test analyzing 10 biomarkers linked to depression in adults. “Part of the reason there’s a stigma for mental illness, including depression, is that people think it’s only in their heads,” Redei says. “As long as there’s no measurable, objective sign, we’re going to stay in that mind-set of ‘Just snap out of it.’ ” Blood tests will take mental illness out of the squishy realm of feelings. And as Lonna Williams, C.E.O. of Ridge Diagnostics, says, they’ll help people understand “it’s not their fault.”

Stuff that seems not-so-great:

Researchers at Imperial College London are closing in on a formula for a new kind of booze — synthetic alcohol, it’s called — that would forever eliminate the next morning’s headache (not to mention other problems associated with drinking).

Maybe it'll be awesome, especially for things like punch, but I feel like taking out the stuff that causes hangovers and serious drunkenness is going to involve taking out a lot of the other important things about drinking, at least on a cultural level.  Personally, my favorite thing about drinking is the narrative aspect -- it feels nice to have a gin and tonic or a glass of whisky, I can't imagine it feeling the same with artificial buzz-water.
