"Come with me as we binge-watch the future." My name is Ari Einbinder This is the journal of my travels into the realms of science, education, reality, and imagination.

tl;dr: Many people derive satisfaction from completing chores, so having autonomous robots do it may be less attractive to many people. Researchers suggest stressing how freed-up time can offer people a chance to derive meaning in other ways, such as more time with family.

The article reminded me of a Ray Bradbury story (I think in the book "dandelion wine") in which an older man rebukes a kid for planting no-mow grass (it only grows so high), as the old man waxed poetic about the joys of mowing his lawn.

Personally, as someone with mental health issues who never seems able to get my sh*t in order, I'm looking forward to getting all the help I can get!

But this is an interesting indication of what shifts society may see as robots become increasingly capable and adopted for everyday uses.

While I am aware and wary of the potential downsides of automation (in particular, job loss), I am very excited about its potential to make expensive services inexpensive; in particular, medical services. I want to see so much more R&D into automating expensive aspects of the medical field, from mundane tasks like the paperwork, to researching and producing new drugs, to automating life-saving medical procedures.

Aside from the obvious value of getting to stay alive, these machines could address doctor shortages across the world, reduce wait times, improve patient outcomes, and make them extremely affordable. This last point is extremely important: In many parts of the world, healthcare is just not affordable or available. This includes remote and developing areas, such as in Africa, as well as in "affluent" places like the US where medical debt is the #1 cause of bankruptcy.

Anyways, I was excited to read this article. The tl;dr is that a robot performed some laproscopic surgery on pigs, performing difficult gastro-intestinal surgery - and it performed well. The machine also planned most of the surgery as well - though there was human doctor oversight.

However, one could imagine a few years from now, a single human surgeon could oversee several of these at once, thereby reducing the need for human surgeons, bringing down costs, etc etc. Cool stuff.

Rare earth elements, like neodymium and dysprosium, are a critical component to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth’s crust and from one another.
Penn State scientists have discovered a new mechanism by which bacteria can select between different rare earth elements, using the ability of a bacterial protein to bind to another unit of itself, or “dimerize,” when it is bound to certain rare earths, but prefer to remain a single unit, or “monomer,” when bound to others.
By figuring out how this molecular handshake works at the atomic level, the researchers have found a way to separate these similar metals from one another quickly, efficiently, and under normal room temperature conditions. This strategy could lead to more efficient, greener mining and recycling practices for the entire tech sector, the researchers state.
“Biology manages to differentiate rare earths from all the other metals out there—and now, we can see how it even differentiates between the rare earths it finds useful and the ones it doesn’t,” said Joseph Cotruvo Jr., associate professor of chemistry at Penn State and lead author on a paper about the discovery published today in the journal Nature. “We’re showing how we can adapt these approaches for rare earth recovery and separation.”

The potential of this new [A.I.] technology is becoming increasingly clear, and the estimates for its impact on the broader economy are mind-boggling. Research firm McKinsey & Company thinks it could add $13 trillion to global economic activity by 2030, whereas Ark Investment Management predicts that number could be $200 trillion.

By way of context, global gdp is currently around $100 trillion.

If M&C are correct, we’re looking at a 10% increase, which is enormous. If AIM is correct, we’re looking at a 200% increase, which is unfathomable. If the result is somewhere in the middle, around $100T, we’re still looking at a 100% increase in global GDP.

Basically, AI is either going to turbocharge the economy, or it’s going to blast our economy into another universe, or something in between.

We are not ready.

This is pretty cool. Instead of using dangerous chemicals to kill mice. Just trick them instead. Non-violent. Cheaper. And can save a TON of food. Pretty awesome. 

Highlights:

In a research paper published today, we show how “chemical camouflage” can prevent house mice finding newly sown wheat seeds. The method reduced mouse damage to wheat crops by more than 60% even during plague conditions, without killing a single mouse....
Rodents are responsible for an estimated 70 million tonnes of grain lost worldwide each year. Even a 5% reduction in these losses could feed more than 280 million people....
When a food is too difficult to find, or an odour is not a useful indicator of food, foragers must give up and search for something else to avoid wasting energy.
Because hungry animals can’t afford to waste effort on odours that don’t lead to food, they are vulnerable to olfactory misinformation and chemical camouflage. As with visual camouflage, if the background, in this case smell, appears the same as the item we are trying to hide, the target item cannot be distinguished.
Animals can also learn about the usefulness of information, making them vulnerable to another form of misinformation – odour pre-exposure. By deploying food odours before food is available, foragers initially attracted to the odour repeatedly receive no reward and learn to ignore it.
When the food does become available, foragers don’t follow the odours because they know they’re unrewarding. We recently used this technique to dramatically improve nest survival for threatened shorebirds at risk from by predation by invasive predators in New Zealand...
After two weeks, our camouflage and pre-exposure treatments had reduced mouse damage by 63% and 74% respectively, compared to the control. We also estimated that 53% and 72% fewer seedlings, respectively, were lost to mice on these plots.

With 7+Billion people on the planet, and all of those possessing and consuming vast amounts of water, and spreading out as human populations do, and accepting that we really can't put the brakes on with climate change as we wish (and knowing only a few countries can curtail, but most won't), is there any benefit to warming that the earth could adapt to. IE, more land mass for expansion and agriculture, better access to more resources, etc. Short of inconvenience for the poor and the rich who line the shores. AND, if the earth warms up, doesn't that increase evaporation of water to move it back into the atmosphere and still collect at the polar caps, considering that space is an infinite constant temperature that assists in drawing off extreme temps as it reaches the upper atmosphere? Does that offer any help between the two of evaporation and atmospheric cooling that could be assisted by the increased atmospheric water content as a thermal conductor? Just curious from a "what if we can't really do anything short of being insanely monstrously radical humans wiping other humans out" perspective. And wouldn't that just increase the amount of CO2 in the atmosphere with all those carcasses anyway? These are sincere questions. It truly is from the "what if it's too late" perspective. How do we adapt in spite of the changes? Are we smart enough to do so? And are there any benefits at all?

Hi JD,

This is how I see it:

"and spreading out as human populations do"

I'm not sure if populations are "spreading out" much these days. Most population trends are toward urbanization: people leaving the countryside to move into big cities. Additionally, forecasts predict a contraction of the human population in the near future.

"is there any benefit to warming that the earth could adapt to. IE, more land mass for expansion and agriculture, better access to more resources, etc. Short of inconvenience for the poor and the rich who line the shores."

It's not just poor and rich. Most civilizations throughout time have settled near water for obvious reasons. Even today, around a quarter of all people live near ocean coasts.

As for benefits of climate change, if there are any, they will be overwhelmingly buried in the mountain of ill effects climate change will have. e.g. Even if we somehow got more cropland from it, crops might not grow if the temperature and weather isn't amenable to it.

"AND, if the earth warms up, doesn't that increase evaporation of water to move it back into the atmosphere and still collect at the polar caps"

Evidently not, considering they're melting at an increasing pace. Also, I don't know if water vapor automatically travels to the poles. It likely has more to do with overall atmospheric circulation patterns, as well as temperature and other factors.

"Does that offer any help between the two of evaporation and atmospheric cooling that could be assisted by the increased atmospheric water content as a thermal conductor?"

Not sure I understood this part.

"Just curious from a "what if we can't really do anything short of being insanely monstrously radical humans wiping other humans out" perspective."

I don't buy into the "kill everyone to save everyone" perspective. I usually tell people who endorse it to start "at home" if they think that. Personally, I think we absolutely *can* solve climate change without genocide (jfc), but the problem is that it will require some personal sacrifices and evidently most people aren't ready for that. But if we're going to take a hardline approach, I'd infinitely support strong policies that are unpopular to lower emissions rather than to start killing people.

"These are sincere questions. It truly is from the "what if it's too late" perspective. How do we adapt in spite of the changes? Are we smart enough to do so? And are there any benefits at all?"

It might be too late in that we're not making the changes we need fast enough to avoid disaster. As for climate adaptation, there are lots of interesting websites and blogs that look at mitigation and adaptation methods. And of course there's a benefit in trying to fight off mass death, even if we can't save the planet to the extent that we'd like.

One sentence to get EV haters to shut up

“I think everyone should be allowed to drive whatever they want - as long as they pay to clean up the emissions they create.”

I’ve used this a bunch. Just watch their heads start to spin as they realize this entirely fair and basic-economics response butts against the reality of how much their emissions will cost them. In a best case scenario, the average combustion-engine driver would be looking at an extra $500/yr (and this is just for the CO2 cleanup; there are other emissions as well). But with the pick-up lovers and less ideal scenarios, they could easily be looking at an extra $2,000/yr to the gov’t for environmental clean-up. After 20 years, could collectively total as much as $40k, or the price of the car itself.

And frankly, that could potentially bring a LOT of money - and thus R&D - into the CO2 cleanup industries, like direct carbon capture, which still needs a lot of work. So their CO2 tax money would really help advance sustainability causes. And meanwhile, EVs are getting faster, longer range, more sustainable, and cheaper each year. (I usually mention all this too as the gears in their heads are slowly turning.)

Enjoy

P.s. “Oh yea?! Well then do you agree that EVs should be taxed for any emissions they may cause in their construction or lifecycle?!” - Yes. Yes, I do.

Coolness

So cool and definitely a game changer!! 😎😎😎

One step closer to Star Trek.

gonna really help in remote and developing areas. super portable an 1/10th the price of a regular ultra-sound machine. really hope it also helps bring down the price of such scans. (and just wait till AI is automatically analyzing the scan as it happens, pointing out potential problem areas.)

Really hope this works and that we see this spread and the tech advance. If everyone can charge their vehicles wirelessly while driving, it’d mean EVs could reduce the size of their batteries; this makes the vehicles less environmentally damaging, improves their mpg (since the battery is a huge part of the weight), improve their safety (less massive vehicles produce less deadly accidents). It could also help us create network where parked cars help stabilize the grid.

Highlights:

Sweden is set to become the first country to implement a functioning charging road for heavy electric vehicles (EVs).

The E-20 is set to be a 21-kilometre stretch, running between Hallsberg and Örebro, with inbuilt charging infrastructure for heavy EVs such as freight and haulage trucks. This innovative move will set the precedent for decarbonised logistics around the world. While construction will begin in 2025, which method of charging will be used has not yet been confirmed...

build wireless charging infrastructure down the centre of the lanes that send out an electromagnetic signal to a coil on the underside of the vehicle, similar to the latest wireless mobile phone charging technology.

“If you are going to have only static charging full battery solution for heavy-duty vehicles, you will get vehicles with a huge amount of batteries that the vehicles need to carry,” said Jan Pettersson, Director of Strategic Development at Trafikverket, the Swedish transport administration.

A recent study found that only 25% of all roads need to be electrified for the public charging system to work. Sweden already plans to electrify a further 1,900 miles of roads by 2045 and will be sharing their findings with Germany and France to learn from each other’s experiences.

Pretty interesting concept though I’m not sure about its feasibility. They basically built robotic jellyfish that can create vertical currents that lift things up the water column. In theory, this can be used to help clean up lots of the plastic and other garbage on the bottom of ocean bodies without really disturbing the environment. Once the debris is near the surface, more traditional water cleaning devices can filter out the garbage.

(Pictured: Two mechanical jellyfish work together to lift a discarded mask.)

Apparently this could be combined with atmospheric water harvesting to make it much more efficient. That’s bc this stuff allows water to flow easily at even sub-zero temperatures.

Now, with atmospheric water harvesting with stuff like a MOF (metallic organic framework), the MOF is excellent at absorbing the water, but it requires help to release it, usually by heating it up. If they could mix these substances and properties, it may requires a lot less heating to get the MOF to shed its water. This is really important bc you can get water from air without any electricity, just relying on the temperature change from night to day - but you’d only collect a bit of water. By adding a solar panel or other electricity source, you can run hot/cold cycles throughout the day, drastically increasing output. Now, if you can lower the time and energy required to do that, you could get even more water output with even less energy input.

This has huge implications as water scarcity becomes an increasingly big problem, and as water-from-air tech continues to be researched and invested in.

Highlights:

Dr. Janiak noticed that the crystals were yellow on some days and red on others. It didn’t take her long to figure out that the crystals would only turn red on days with humidity levels higher than 55%. When humidity levels fell below this level, the crystals would go back to being yellow....

Why do these crystals have such special properties? This question started a nearly ten-year investigation, which initially focused on explaining the mechanism behind the color change....

He wanted to know how the crystals would behave when subjected to different temperatures and humidity levels: “I was intrigued by the color change and wanted to explore what was happening at the atomic scale,” he explains...

One day, he observed something strange happening at temperatures below zero degrees Celsius. “I noticed that the crystal still changed color at sub-zero temperatures. Initially, I thought that there was something wrong with the experimental setup or the temperature controller, as crystal hydrates are not supposed to release water at such low temperatures,” he explains...

The channels in the crystal are only one nanometre wide – one-thousandth the diameter of a human hair. It was already known that, at the nanoscale, water can remain mobile within channels at temperatures below 0 °C. However, this study showed for the first time that such channels can also allow the uptake and release of water at temperatures far below its normal freezing point...

Were it not for the color-changing behavior of the crystals in the first place, they would not have become aware of the ultralow temperature water loss capability: “Who knows,” says Prof. Barbour, “there may be many other materials out there with the ability to absorb and release water at very low temperatures, such as metal-organic frameworks and covalent organic frameworks.” “We simply do not know about it because we have not been able to visualize it. Now that we do know that such behavior is possible, it opens a whole new field of research and potential applications...”

Highlights:

The AI system makes a best guess at a recipe for a desired material and then iterates the reaction conditions as robots try to create physical samples. The new setup, known as the A-Lab, is already synthesizing about 100 times more new materials per day than humans in the lab can manage...  

Previous automation efforts randomly mixed compounds in search of new materials, Ceder says, but the new AI-driven approach is more akin to the way traditional chemists do their jobs. The AI starts by coming up with a plausible way to synthesize a material, using its understanding of chemistry. It guides robotic arms to select among nearly 200 different powdery starting materials, containing elements such as lithium, nickel, copper, iron, and manganese. After mixing the precursors, another robot parcels out the mix into a set of crucibles, which are loaded into furnaces where they can be mixed with gases such as nitrogen, oxygen, and hydrogen. The AI then determines how long to bake the different mixes, the temperatures, drying times, and so on... 

LBNL researchers have spent the past several months working out the kinks in their system and testing it. In the process, the A-Lab has produced more than 40 target materials—about 70% of the compounds it has set out to produce. “I have made more new compounds in the last 6 weeks than my whole career,” Ceder says.

The links between neurons are called synapses. What exactly is a synapse, and what happens there? It’s basically a connection: one cell talking to another. A brain cell, or a neuron, has a large main body, with small strands sticking out.

Really interested in this considering current glass manufacturing is not sustainable and we’re literally running out of sand.

The research group, led by Professor Yan Xuehai from the Institute of Process Engineering (IPE) at the Chinese Academy of Sciences, fabricated a type of glass using biologically derived amino acids and peptides. These naturally occurring molecules normally break down into CO2 and compounds called amines at high temperatures, making them unsuitable for glass. But in the study, the researchers chemically modified them so that, when heated, they would melt before the onset of decomposition. This meant that the research team was able to perform the ‘heating-quenching’ procedure used in traditional glassmaking. In this procedure, the modified molecules were melted into a supercooled liquid which was then quickly ‘quenched’ – cooled at high pressure – to form the glass.
The resulting material had the kinetic and thermodynamic properties, as well as the performance, of traditional glass. These included excellent optical characteristics, good mechanical properties, and flexible processability. On top of this, the material was biodegradable and recyclable using energy-efficient processes. The researchers also claim that it would be possible to 3D print the new glass, and use it in mould casting processes.
According to Professor Yan, “The concept of biomolecular glass, beyond the commercially-used glasses or plastics, may underlie a green-life technology for a sustainable future.” He pointed out, though, that the biomolecular glass is currently in the laboratory stage, and it will be a long time before it is ready for large-scale commercialisation.

“Scientists are often taught to “just stick to the facts” when communicating their research findings, particularly on controversial topics.

“Sticking to the facts” seems like solid, simple advice, and moreover it is grounded in science’s values to be as objective and evidence-based as possible.

However, it is counterintuitive (and not a little ironic) that by “sticking to the facts,” we ignore a wealth of evidence on effective science communication.

In our zeal to communicate the evidence of science, we neglect the evidence of science communication. (…)

We often focus our communication efforts on trying to persuade publics on the “right way” to think.

But research suggests that it is incredibly difficult to change minds, especially on controversial issues.

There is much exciting new work that points to the potential of forgoing our obsession with getting people to think differently, to focus more on getting people to act differently.

This research suggests that instead of targeting individual attitude change, seeking to change physical and social environments to support behavioural changes may in turn lead to shifts down the road in beliefs, identities, and future actions.

In other words, rather than changing minds to change behaviours, this body of scholarship suggests that we should change behaviours to change minds.

For example, increasing accessibility to and comfort of public transportation options may result in fewer driving miles, and increase public support for shifting subsidies from highways to rail. (…)

This scholarship suggests that while big media platforms and social media can help to get an idea “out there,” such visibility rarely result in widespread behaviour change.

Rather, where ideas can affect change is through tapping into smaller social networks by means of strong social ties, which provide safe spaces for innovation to occur within one’s social network.

This can support the uptake of new ideas that can then spread to other social networks once they are established.

For example, to increase adoption of solar panels in a city, it would be more effective to target most homeowners in a single neighbourhood, rather than spreading the message thinly across multiple neighbourhoods.”
