Short paragraph. Big implications:
Realizing robust quantum information transfer between long-lived qubit registers is a key challenge for quantum information science and technology. Here, we demonstrate unconditional teleportation of arbitrary quantum states between diamond spin qubits separated by 3 m. We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin. By realizing a fully deterministic Bell-state measurement combined with real-time feed-forward quantum teleportation is achieved upon each attempt with an average state fidelity exceeding the classical limit. These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing.
Decent explanation (at least from what I know) in this article. Excerpt:
Scientists in the Netherlands have moved a step closer to overriding one of Albert Einstein’s most famous objections to the implications of quantum mechanics, which he described as “spooky action at a distance.”
In a paper published on Thursday in the journal Science, physicists at the Kavli Institute of Nanoscience at the Delft University of Technology reported that they were able to reliably teleport information between two quantum bits separated by three meters, or about 10 feet.
Ten feet may not sound like much, but it is a huge increase — previously, reliable teleportation of information was on the scale of just billionths of a meter. This change opens the door to functional quantum computing, which would have the same relation to current computing power that current computing power has to mechanical calculating machines of about the WWII era.

The doctor looked up from her laptop, where the patient’s medical history was displayed. “Have you been doing those exercises we discussed?”
“Every day. Well, most days. I miss doing them sometimes if I’m traveling or if the kids are running late in the morning.”
“You do understand that they’re really important, right?” She looked her patient right in the eye. “Every. Single. Day.”
He looked down at his feet, dangling off of the exam table. “Sorry. I’ll try and do better.”
“I certainly hope so. Lifespan is correlated with how tall you are. Short people just do not live as long.” She glanced at the laptop again. “Now, how about your meds & vitamin supplements? Taking those?”
The patient didn’t look up. “The vitamins, yes. Religiously. But the prescriptions … they’re *SO* expensive. My insurance company doesn’t cover them, because my shortness is considered a lifestyle choice.”
The doctor shook her head. “Yeah, I know. Medical science still considers height as being only partially due to genetics. But still, you really have to do your best. Take the meds. I’ll get you some free samples — the sales reps are always leaving that stuff for us.”
“Thanks.” He looked up. “Doc, what do you think of maybe the surgical option?”
“Does your insurance cover it?”
“Surprisingly, yes. Well, not here in the States.”
“What do you mean?”
“They’ve got a thing set-up with a clinic in India: for the whole six-month breaking & lengthening process, they cover it. Lots less expensive than here in the US.”
The doctor made a face. “I know they’re supposed to do good work … ”
“Doc, they can add two inches to my overall height.”
“Yes, but at what risk?”
“Not much. Not too different than having it done here.” His face brightened a bit. “I’m not getting any younger. You know what a difference it can make for dating and career. Just think … I could be almost six foot tall!”
The doctor sighed. “Look, I know this is hard. But stick with the stretching exercises and meds I’ve prescribed. Maybe start going to a rack therapist — they can usually add up to an inch in the course of a year.”
“And watch your diet. Stay away from those short sugars. Proteins are long. Makes a difference.”

He turned the hand-held on, did a quick check to make sure it had the software and apps he’d asked for. Everything was there. He’d pick up a burner phone later, and swap the SIMM card into the hand-held. He turned off the hand-held, dropped it into a special pocket inside his vest – one which was RF-blocked. He had another such compartment in his satchel. These, like the wallet/holster, were prohibited items and grounds for arrest in the States, but while they would raise an eyebrow in the UK they weren’t technically illegal.
And even earlier did a blog post about a commercial product to isolate a phone that way when I first thought of it: Off the Grid Bag. (Which actually works quite well, as a matter of fact; I got one of those and have tested/used it exactly as intended.)
Well, now someone has come up with the idea of making actual articles of clothing using the same idea:
Sure, you could just turn off your phone. But that would be too easy. Now, thanks to Trident (yes, the chewing gum) and fashion designer Kunihiko Morinaga, you can repel all cellphone transmissions simply by wearing these hip threads called Focus Life Gear—made of radio frequency shielding fabric.
I suppose that since I haven’t actually published St Cybi’s Well yet I can’t claim to have predicted this tech, but no matter — it’s an obvious application of existing technology and desire for privacy. But still, kinda fun.
Tip of the radio-wave-blocking hat to Tim for the news item! Thanks!

“Mr. Jones? This is Jane from Universal Replacements.”
“I was just calling to tell you that your new left ear will be ready for delivery on Friday. Which medical clinic will be doing the installation?”
“Acme Doctors over on … hey, wait, did you say LEFT ear?”
“That’s right, sir.”
“No, no, no, there’s been a mistake. I ordered a RIGHT ear when I sent in the cell sample.”
“I’m sorry sir, my records clearly indicate that you ordered a LEFT ear when you placed your order.”
“That can’t be right, I know I ordered a RIGHT ear! I don’t need a new LEFT ear!”
“I’m sorry, sir … ”

Synthetic biology: New letters for life’s alphabet
The five bases found in nucleic acids define the ‘alphabet’ used to encode life on Earth. The construction of an organism that stably propagates an unnatural DNA base pair redefines this fundamental feature of life.

Sorry about the sparseness of posting lately. I’ve been … busy. Have had a couple of interesting things happen which could play out in some very good ways. One is still enough in an embryonic stage that I won’t mention anything about it yet, but the other is far enough along that I’ll share: there’s a literary agent who is potentially interested in representing me, something which I have been thinking about for a while.
And it seems like a good enough fit that I took all of last weekend to put together a submission package for formal consideration. That meant going through and doing fairly thorough revisions to the first few chapters of St Cybi’s Well, using the feedback I have gotten from half a dozen ‘beta readers’, as well as composing a formal synopsis of the book. Frankly, both were a lot of work, and somewhat skewed my normal work schedule such that it is just now getting back to what passes for normal in my life.
But it was also helpful, and forced me to clarify some things which I had left unfocused for the rest of the book. Because of the way I am writing this (using Scrivener), it has been fairly easy for me to block out both the overall arc of the book as well as character developments. But doing so has been based on chapter notes more than anything, meaning that it was still somewhat in flux. Creating a full synopsis meant that I had to put the whole thing into one coherent document. And even though it was something of a pain in the butt, the result is helpful.
I’ll keep you posted as to any concrete developments.

Remember this scene from Aliens?
Considered a classic, and rightly so. But I’ve always thought that a big part of the brilliance of it is how it sets up what happens immediately after:
Back at the groups’ table, Bishop holds up his hand and examines a tiny cut closely.
BURKE: I thought you never missed, Bishop?
To Ripley’s horror, a trickle of white synthetic blood runs down his finger. Ripley spins on Burke, her tone accusing.
RIPLEY: You never said anything about an android being on board! Why not?!
BURKE: It never occurred to me. It’s common practice. We always have a synthetic on board.
BISHOP: I prefer the term ‘artificial person’ myself.

Oh, one more thing: in observation of Mother’s Day, the Kindle edition of Her Final Year is available for free download through Sunday, May 11th. If you’re new here, just a quick note: this is our care-giving memoir about the challenges and rewards of caring for someone with dementia, as well as the long recovery/reflection period which comes after. It seems to have helped a lot of people. Perhaps it can help you or someone you know.
