We are relatively close to a world of computing power that will catapult humanity forward or destroy it

The New Yorker has posted an excellent article about the race to build the world’s first viable quantum computer:

Classical computers speak in the language of bits, which take values of zero and one. Quantum computers, like the ones Google is building, use qubits, which can take a value of zero or one, and also a complex combination of zero and one at the same time. Qubits are thus exponentially more powerful than bits, able to perform calculations that normal bits can’t. But, because of this elemental change, everything must be redeveloped: the hardware, the software, the programming languages, and even programmers’ approach to problems.

On the day I visited, a technician—whom Google calls a “quantum mechanic”—was working on the computer with an array of small machine tools. Each qubit is controlled by a dedicated wire, which the technician, seated on a stool, attached by hand.

The quantum computer before us was the culmination of years of research and hundreds of millions of dollars in investment. It also barely functioned. Today’s quantum computers are “noisy,” meaning that they fail at almost everything they attempt. Nevertheless, the race to build them has attracted as dense a concentration of genius as any scientific problem on the planet. Intel, I.B.M., Microsoft, and Amazon are also building quantum computers. So is the Chinese government. The winner of the race will produce the successor to the silicon microchip, the device that enabled the information revolution.

A full-scale quantum computer could crack our current encryption protocols, essentially breaking the Internet. Most online communications, including financial transactions and popular text-messaging platforms, are protected by cryptographic keys that would take a conventional computer millions of years to decipher. A working quantum computer could presumably crack one in less than a day. That is only the beginning. A quantum computer could open new frontiers in mathematics, revolutionizing our idea of what it means to “compute.” Its processing power could spur the development of new industrial chemicals, addressing the problems of climate change and food scarcity. And it could reconcile the elegant theories of Albert Einstein with the unruly microverse of particle physics, enabling discoveries about space and time. “The impact of quantum computing is going to be more profound than any technology to date,” Jeremy O’Brien, the C.E.O. of the startup PsiQuantum, said recently. First, though, the engineers have to get it to work.

“Getting it to work is tricky, not least because currently “the processor relies on superconductivity, meaning that, at ultracold temperatures, its resistance to electricity all but disappears. When the temperature surrounding the processor is colder than the deepest void of outer space, the computations can begin.”

They are getting there, slowly. And when they do:

Fault-tolerant quantum computers should be able to simulate the molecular behavior of industrial chemicals with unprecedented precision, guiding scientists to faster results. In 2019, researchers predicted that, with just a thousand fault-tolerant qubits, a method for producing ammonia for agricultural use, called the Haber-Bosch process, could be accurately modelled for the first time. An improvement to this process would lead to a substantial decrease in carbon-dioxide emissions. Lithium, the primary component of batteries for electric cars, is a simple element with an atomic number of three. A fault-tolerant quantum computer, even a primitive one, might show how to expand its capacity to store energy, increasing vehicle range. Quantum computers could be used to develop biodegradable plastics, or carbon-free aviation fuel. Another use, suggested by the consulting company McKinsey, was “simulating surfactants to develop a better carpet cleaner.” “We have good reason to believe that a quantum computer would be able to efficiently simulate any process that occurs in nature,” Preskill wrote, a few years ago.

The world we live in is the macroscopic scale. It is the world of ordinary kinetics: billiard balls and rocket ships. The world of subatomic particles is the quantum scale. It is the world of strange effects: interference and uncertainty and entanglement. At the boundary of these two worlds is what scientists call the “nanoscopic” scale, the world of molecules. For the most part, molecules behave like billiard balls, but if you zoom in close enough you begin to notice quantum effects. It is at the nanoscopic scale that researchers expect quantum computing to solve its first meaningful problems, in pharmaceuticals and materials design, perhaps with just a few hundred fault-tolerant qubits. And it is in this discipline—quantum molecular chemistry—that analysts expect the first real money in quantum computing to be made. Quantum physics wins the Nobel. Quantum chemistry will write the checks.

This is a world of wondrous advances that will largely take place after I am gone. But it is exciting nonetheless for me. And also scary to think about, because the mischief and criminality that currently emanate from the intersection of capitalism and science under silicon-chip computer processing will be magnified unimaginably.

Whether quantum computing will help engender a world of greater community and cooperation, or a world where humanity is that much closer to destroying itself, remains to be seen.

Quantum computers, such as the one shown here, are learning to overcome the barriers that not long ago seemed insurmountable.

How naming the James Webb telescope ignored important history around LGBT issues

The New York Times’ Michael Powell is described on that newspaper’s web site as “a national reporter covering issues around free speech and expression, and stories capturing intellectual and campus debate.”

But if you follow Powell’s writing closely, it’s clear through his choice of topics that his sympathies lie with those who think “wokeism” has run amuck, even as he buffers his personal biases in the anodyne language many mainstream media reporters use to seem as if they are neutral when they are not.

Powell clearly thinks that undergraduates and grad students at, say, Sarah Lawrence or Yale Law School being inflexible in their beliefs — inflexibility in personal crusades being a hallmark, for many, of being university students — are a greater threat to free speech than Elon Musk pushing a fascist agenda on Twitter. This is a hallmark of a different kind, that being the tendency of well-to-do white guys at the New York Times to see every bit of pushback against their beliefs and history as a threat to civil society.

Powell has piece up today that has great personal interest for me as a gay man who’s experience all manner of discrimination:

NASA’s decision to name its deep-space telescope after James E. Webb, who led the space agency to the cusp of the 1969 moon landing. This man, they insisted, was a homophobe who oversaw a purge of gay employees.

Hakeem Oluseyi, who is now the president of the National Society of Black Physicists, was sympathetic to these critics. Then he delved into archives and talked to historians and wrote a carefully sourced essay in Medium in 2021 that laid out his surprising findings.

“I can say conclusively,” Dr. Oluseyi wrote, “that there is zero evidence that Webb is guilty of the allegations against him.”

That, he figured, would be that. He was wrong.

The struggle over the naming of the world’s most powerful space telescope has grown yet more contentious and bitter. In November, NASA sought to douse this fire. Its chief historian, Brian Odom, issued an 89-page report that echoed Dr. Oluseyi’s research and concluded the accusations against Mr. Webb were misplaced.

NASA acknowledged that the federal government at that time “shamefully promoted” discrimination against gay employees. But Mr. Odom concluded: “No available evidence directly links Webb to any actions or follow-up related to the firing of individuals for their sexual orientation.”

Critics called the NASA report “selective historical reading.” And they reframed their argument, saying that Mr. Webb should be held responsible for any anti-gay activity at NASA and at the State Department, where he had previously been a high-ranking official.

In a blog written with three fellow scientists, Chanda Prescod-Weinstein, a cosmologist at the University of New Hampshire with a low six-figure Twitter following, said that it was highly likely that Mr. Webb “knew exactly what was happening with security at his own agency during the height of the Cold War,” adding, “We are deeply concerned by the implication that managers are not responsible for homophobia.”

This controversy cuts to the core of who is worthy to memorialize and how past human accomplishment should be balanced with modern standards of social justice. And it echoes a heated debate among historians over presentism, which is the tendency to use the moral lens of today to interpret past eras and people.

The entire way this is worded suggests, once again, that Powell agrees with those who think that Webb should not be judge by the standards of today for those things he did back when homosexuality was considered a mental illness.

But this is the same argument that some white racists have used to argue against the tearing down of Confederate statues, namely that we ought not judge former slaveholders by the standards of today when owning slaves was normal during a time when blacks were considered sub-human.

This is ridiculous, of course.

It does appear that there have been homophobic words and intent that were, early in this controversy, unfairly attributed to James Webb. Many of those errors have been corrected, though sometimes not refuted in as public a way as were the original accusations against him.

But Webb did at least acquiesce when the “Lavender Scare” was in full-swing, and gay and lesbian NASA employees were being forced from their jobs and careers and committing suicide.

That fact might be mitigated with the argument that Webb was a product of his time. But not by much. They were still being forced out of jobs by accusations that had nothing to do with their abilities as scientists and administrators. And just as with slaveholders vs. abolitionists, there were many people in the time of the Lavender Scare who were able to come to the fully rational conclusion that firing gay people because they were gay was immoral and unnecessary.

Some of those people were likely uncomfortable with the subject of homosexuality. But they also knew that what someone did in their private romantic life had no bearing on their ability to do physics. Yet James Webb, an educated man, went along with the mob.

Which begs the question: Why choose Webb at all? There are so many other deserving people for whom that telescope could have been named, some of them women and people of color. And none of those people have Webb’s baggage, all of which was brought to the attention of NASA administrators at a time when changing the name of the project would have been easier.

The reason it wasn’t changed is because the Old Boy network had decided to honor one of its own, and they were not going to let some inconvenient history, nor noisy activists, alter their decision.

Because that is the way the Old Boys Network operates. And trying to dress that up in arguments about free speech tells us all we need to know about Michael Powell and the people who argue that we should stick with the name James Webb.

The New York Times attacks dogs and loves cats

A great many things have outraged me in the last couple months, but this quote in a New York Times article sent me over the edge:

“Dogs were artificially selected hundreds or thousands of years ago based precisely on their capacity to be trained, whether as sheepdogs, hunting dogs or something else,” Sarah Jeannin, a dog behavior expert at the Université Paris Nanterre who was not involved in the new study.

Dr. Jeannin disputed the stereotype that dogs are closer to humans than cats. “People say that dogs are a man’s best friend, that you can trust them and that they are very loyal. But we don’t know what dogs actually think,” she said. “It’s really just projection by us that dogs are in love with us.”

First of all, I would expect this from a French person. If someone would have read me this quote and not told me who said it, I would have followed with, “This is ridiculous. What are they? Parisian?”

With that unpleasantness out of the way, Dr. Jeannin has clearly not read the studies involving dogs, owners and their oxytocin levels. You can find one here. You can find another here. You can find more.

The only reason we can’t say with certainty that our dogs literally “love” us is because they cannot form sentences like, “I am jumping up and down and marking when I see after you’re gone because I love you so much.”

But anyone who’s ever been loved by a dog knows: your dog loves you totally and unconditionally. And no dog lover needs to measure oxytocin levels to know that with every fiber of their being.

I once took in a stray cat that I ended up loving dearly. It was heart-rending when I was in the room with him as Frank the stray cat took his last failing-kidney breaths.

But I was never quite sure that Frank loved me because the only overt behavioral act he regularly displayed toward me was that he always pissed in my shoes and nobody else’s. “You know,” I’d say to my roommates, “I think Frank might be warming up to me because he hasn’t shit in my slippers for two weeks.”

So there, Dr. Jeannin. Take your anti-dog, pro-cat fake news and keep it where it belongs. In France. Which hates perros and has a sad bias in favor of gatos.

Actually, I think that might be Spanish.

But you get the picture.

WaPo has an amazing story up about that massive beagle rescue

What a remarkable Washington Post story, with remarkable pictures.

The first beagle out that day had brown eyes and a chunk missing from his left ear. His tail was a nub. It went from tan to white, then disappeared, maybe bitten off in a fight or caught in a cage door.

The 1-year-old had never been given a name — just an identification code, ‘CMG CKA,’ tattooed in blue-green on the flap of his left ear. Like the thousands of other beagles bred for research at Envigo, a sprawling complex tucked deep in rural Virginia, he’d spent his entire life in a cage surrounded by the relentless barking of other dogs.

Now, on a Thursday in late July, that was about to change.

Uno, as he was immediately dubbed by his rescuers, and 3,775 other beagles were being sprung from their misery in an unprecedented animal welfare seizure.

After years of alarm from animal rights advocates and state legislators, after U.S. Department of Agriculture inspectors found maggot-infested kibble, 300 dead puppies and injured beagles being euthanized, after an undercover investigation by the People for the Ethical Treatment of Animals, and after a lawsuit filed against Envigo by the Justice Department, the Indianapolis-based company had reached a settlement with the federal government. It agreed to shut down the Virginia breeding operation — admitting no wrongdoing and receiving no punishment or fines — rather than make what the CEO of its parent company called “the required investments to improve the facility.”

In July, U.S. District Court Judge Norman K. Moon approved the surrender of Envigo’s beagles to the Humane Society of the United States, giving the nonprofit group just weeks to organize the biggest rescue in its 67-year history.

“There’s been nothing, ever, like this. Just the sheer volume of dogs, or really, any animal,” said Kitty Block, the Humane Society’s president and chief executive.

What followed was two months of beagle mania, as people across the country showered the Humane Society with $2.2 million in donations and clamored to adopt the dogs. Prince Harry and Meghan Markle took in a beagle. So did the governor of New Jersey and the chief meteorologist at a Virginia news station.

But the beagle emancipation was cloaked in secrecy. Almost no one was allowed to see the dogs leave Envigo.

Why all the secrecy is never made completely clear. Was it meant to benefit the beagles or protect the horribly company involved?

BTW, Envigo is still breeding lab animals, including beagles. The fact that the people who ran that breeding facility are not in jail shows how far we have to go on even the most basic animal rights issues

Anyway, the entire story is remarkable, except for this part:

The puppy pursuers outside the Humane Society far outnumbered voters at a neighboring polling place for the Wisconsin primary. One man — who arrived at the Humane Society with an injured crow — appeared bewildered by all the people, asking if they were there for one of the gubernatorial candidates.

I love animals as much as (or more than) the next person, but I love humans just as much. And I worry about the future we are leaving innocent children of countless current and upcoming generations.

That people can mobilize to this extent to save beagles (and yay! that they do) but not be bothered to vote, or care enough to reject the proto fascism of the GOP, is a huge problem in this society.

And I’ve got news for GOP-loving animal lovers: the lives of animals are not going to get any better with Republicans in control of your statehouse or the Congress.

Scientists find 31,000-year-old skeleton with signs of medical amputation

The only surgery I’ve had was after some inattentive goon in an SUV made a wide right turn in front of me at a Boston intersection, which sent me flying off my Vespa and into a fire hydrant.

Shattered right ankle, mostly. What I remember most vividly about the incident is how the city ambulance seemed to have no suspension whatsoever, so the entire time between the accident scene and Boston Medical Center we were hitting Boston’s ubiquitous potholes. Everything in the ambulance — including my shattered ankle — would bounce violently.

What a relief it was when we arrived at the emergency room and they gave me a shot of pain killer. And then put me under for emergency surgery.

I was in that hospital bed for a couple of days and nights while they gave me shots of glorious morphine every four hours — I watched the clock closely, let me tell you.

And I remember thinking, “I cannot imagine that they used to do all of this without pain killers of any kind. Surgery without being asleep.”

Life before general anesthesia must have been grim and terrifying.

On a related note, researchers in the journal Nature have revealed that they found a very old skeleton that shows signs of pre-planned amputation that had healed:

A 31,000-year-old skeleton missing its lower left leg and found in a remote Indonesian cave is believed to be the earliest known evidence of surgery, according to a peer-reviewed study that experts say rewrites understanding of human history.

An expedition team led by Australian and Indonesian archaeologists stumbled upon the skeletal remains while excavating a limestone cave in East Kalimantan, Borneo looking for ancient rock art in 2020.

The finding turned out to be evidence of the earliest known surgical amputation, pre-dating other discoveries of complex medical procedures across Eurasia by tens of thousands of years.

By measuring the ages of a tooth and burial sediment using radioisotope dating, the scientists estimated the remains to be about 31,000 years old.

Palaeopathological analysis of the remains revealed bony growths on the lower left leg indicative of healing and suggesting the leg was surgically amputated several years before burial.

Dr Tim Maloney, a research fellow at Australia’s Griffith University who oversaw the excavation, said the discovery was an “absolute dream for an archaeologist”.

The stuff of nightmares.

Are we moving closer to understanding some animals’ languages?

If you watch and love (as much as I do) the Amazon production of “The Boys,” the series about a world populated with deeply flawed superheroes, you’re no doubt familiar with the character called The Deep, the underwater-breathing, talk-to-the-fishies, self-involved numbskull who is pretty, but dim-witted.

The Deep is also wracked by self-doubt, as in this S1E4 exchange with his therapist:

The Deep: I mean, yeah, I can talk to fish. So what? How often do you need to be saved by a school of salmon?

Psychiatrist: Kevin, that’s just not true. Where would that Carnival cruise ship be without you?

The Deep: Yeah, I know.

Deep’s ability to talk to the animals presents him as a sort of perverted aquatic Dr. Doolittle.

That kind of animal-to-human two-way communication may never happen. But thanks to machine learning, we might not be that far off from understanding what some animals are saying to each other, as this New York Times article by Emily Anthes explains:

Machine-learning systems, which use algorithms to detect patterns in large collections of data, have excelled at analyzing human language, giving rise to voice assistants that recognize speech, transcription software that converts speech to text and digital tools that translate between human languages.

In recent years, scientists have begun deploying this technology to decode animal communication, using machine-learning algorithms to identify when squeaking mice are stressed or why fruit bats are shouting. Even more ambitious projects are underway — to create a comprehensive catalog of crow calls, map the syntax of sperm whales and even to build technologies that allow humans to talk back.

“Let’s try to find a Google Translate for animals,” said Diana Reiss, an expert on dolphin cognition and communication at Hunter College and co-founder of Interspecies Internet, a think tank devoted to facilitating cross-species communication.

The field is young and many projects are still in their infancy; humanity is not on the verge of having a Rosetta Stone for whale songs or the ability to chew the fat with cats. But the work is already revealing that animal communication is far more complex than it sounds to the human ear, and the chatter is providing a richer view of the world beyond our own species.

I find it really intriguing that machines might help us to feel closer to animate life, that artificial intelligences might help us to notice biological intelligences,” said Tom Mustill, a wildlife and science filmmaker and the author of the forthcoming book, “How to Speak Whale.” “This is like we’ve invented a telescope — a new tool that allows us to perceive what was already there but we couldn’t see before.”

Studies of animal communication are not new, but machine-learning algorithms can spot subtle patterns that might elude human listeners. For instance, scientists have shown that these programs can tell apart the voices of individual animals, distinguish between sounds that animals make in different circumstances and break their vocalizations down into smaller parts, a crucial step in deciphering meaning.

The Deep, who is paradoxically not very deep.

Northwestern scientists may have found a way to break down some “forever” chemicals

PFAS — so-called “forever chemicals” — are everywhere. So much so that you or someone (or someones) you love are probably already carrying toxic levels of the chemicals, and will likely have some adverse health effects because of that contamination. (It’s not even clear how much of an exposure means you increase levels of, for example, certain cancers or endocrine disruption diseases.)

An estimated 26,000 U.S. sites are contaminated with some form of PFAS. At least six million Americans are estimated to have drinking water containing some form of PFAS above the existing safe limits recommended by the U.S. EPA.

Coming up with ways rid of these PFAS chemicals from our environment has been difficult because the properties that make them so durable in everyday use are the same ones that make them tough to destroy.

For over a century, our world has been made of plastic. It’s in everything from firefighting foam to water bottles to nonstick pans, yielding convenient products that last. But in the long run, plastic releases hazardous chemicals, called Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), that seep into the soil and groundwater. These “forever chemicals” are everywhere today: in our drinking supplies, our food, the air, and even our bodies, where they can lead to unwelcome consequences, including cancer, infant development problems, and weakened immunity.

Scientists have been working on ways to destroy PFAS chemicals that permeate our environment, but no easy method exists. That’s because these standoffish compounds don’t react to anything—not biological or other chemical agents. They stick only to each other and resist being torn apart. Current methods require“very harsh conditions to decompose these compounds,” according to chemists at Northwestern University in Evanston, Illinois. Until now, how to break those PFAS bonds has been unclear.

That team’s recent work, published in the journal Science on August 18, proves that the stubborn power of PFAS bonds can, in fact, be broken. The scientists discovered a way to disintegrate two concentrated, toxic forms of PFAS into smaller, innocuous compounds that decompose. Using low heat, a solvent, and sodium hydroxide (lye, the basis of some soaps), the method is both simple and inexpensive. It works for two major categories of PFAS permeating the environment today: perfluorooctanoic acid (PFOA) and one of its common replacements, known as GenX.

The traditional difficulty in destroying a PFAS compound lies in its many carbon-fluorine bonds, which organic chemists know as the strongest bonds. They require immense heat (about 400 degrees Celsius) and pressure to break, which can lead to cases of air contamination during incineration, William Dichtel, the lead author of the new study, explains in a news release. “In New York state, a plant claiming to incinerate PFAS was found to be releasing some of these compounds into the air,” says Dichtel, a professor of chemistry. “The compounds were emitted from the smokestacks and into the local community.” And burying PFAS just causes them to contaminate the environment after a few decades, he adds.

French physicist apologizes for tweeting a fake James Webb telescope image that was actually a slice of chorizo

In a world where scientists and their reliability are under constant attack by right-wing forces to the point that even the public, which doesn’t understand the scientific method anyway, also distrusts them, this is a really stupid stunt.

A senior French scientist has apologised after tweeting a picture which he said was from the James Webb Space Telescope — but which was not quite what it seemed.

Etienne Klein, a director at France’s Atomic Energy Commission, posted a picture purportedly showing Proxima Centauri, the closest star to our sun.

“This level of detail … a new world is revealed every day”, he enthused in the tweet, sent to more than 90,000 followers on Monday.

However, Professor Klein has now admitted that the glowing celestial body shown was in fact nothing more than a slice of Spanish chorizo sausage.

Apologising for what he described as “a scientist’s joke”, he said his aim had been to remind people to “be wary of arguments from people in positions of authority”.

What a crank.

I did a bit of checking on Klein and found this on his Wikipedia page:

In December 2016, Science magazine, a publication of the American Association for the Advancement of Science, reported that Popular French physicist Étienne Klein was responsible of a plagiarism, his work was said to be plagiarizing the novelist Stefan Zweig and other authors.

Seems as if Klein has a bit of experience in fake scientific authority.

Are we on the cusp of a brave new world of artificial human embryos?

That reality is still a ways off, but scientists in Israel are getting closer, according to Jacob Hanna, a biologist at the Weizmann Institute:

Hanna tells MIT Technology Review he is already working to replicate the technology starting with human cells and hopes to eventually produce artificial models of human embryos that are the equivalent of a 40- to 50-day-old pregnancy. At that stage basic organs are formed, as well as tiny limbs and fingers.

Researchers can already print or grow simple tissues, like cartilage or bone, but making more complex cell types and organs has proved difficult. An embryo, however, starts building the body naturally.

“The vision of the company is ‘Can we use these organized embryo entities that have early organs to get cells that can be used for transplantation?’ We view it as perhaps a universal starting point,” says Hanna.

Embryonic blood cells might be collected, multiplied, and transferred to an elderly person in order to reboot the immune system. Another concept is to grow embryonic copies of women with age-related infertility. Researchers could then collect the model embryo’s gonads, which could be further matured, either in the lab or via transplant into the woman’s body, to produce youthful eggs.

The startup, funded so far with seed capital from the venture firm NFX has been briefing other investors, and its pitch materials state that its mission is “renewing humanity—making all of us young and healthy.”

Renewal Bio’s precise technical plan remains under wraps, and the company’s website is just a calling card. “It’s very low on details for a reason. We don’t want to overpromise, and we don’t want to freak people out,” says Omri Amirav-Drory, a partner at NFX who is acting as CEO of the new company. “The imagery is sensitive here.”

“Sensitive” may be the biggest understatement I read this week.

There are so many terrible things that can come of this. Certainly also some good. Any inclination I have that this might be useful is tempered by the fact that we live under capitalism, and capitalism will always find ways to use scientific discoveries like these in evil ways that will harm society as a whole.

A plastic model of a human fetus. They can’t come close to artificial embryos taken to this point of development — yet.
