The topic of batteries made from trees opens up a world of possibilities for a sustainable future. As we become more aware of the impact of traditional batteries on the environment, alternative options are becoming more appealing. This article sheds light on the development of tree-based batteries and their potential to revolutionize the way we power our devices.

However, the discussion should not end here. There are still many questions that need to be addressed, such as the scalability of this technology and the potential impact on the forestry industry. Furthermore, how can we ensure that the process of producing tree-based batteries is truly sustainable and does not cause further harm to the environment?

As we move towards a more sustainable future, it is crucial to explore and develop alternative solutions for our energy needs. The development of tree-based batteries is a step in the right direction, and it will be interesting to see how this technology evolves in the future and how it can contribute to a more sustainable and cleaner planet.

>Greg Spanjers, program manager for rocket cargo at AFRL, said the military envisions a future when it could be cheaper to send cargo via rocket than by transport aircraft. In a national security or humanitarian crisis, a launch vehicle would fly from Cape Canaveral, for example, and either land on an austere field to deliver cargo or airdrop it.
>
>For the rocket cargo program to be viable, Spanjers said, DoD expects to use launch providers that fly frequently so they can offer competitive pricing. “To make this a success, we need a very high launch rate, and we need to have systems that reenter and that can bring a high down mass,” he added.

Here’s one more reason to love a good mushroom: one day, you might be able to make headphones, memory foam for shoes, or even aircraft exoskeletons with it. Researchers just assessed the engineering possibilities with one particularly impressive mushroom and found that it might be able to replace plastic in a whole bunch of different use cases.

Using mushrooms instead of plastic could cut down on the mountains of waste humans create. Plastics made out of fossil fuels are actually really difficult to recycle and usually wind up cluttering landfills, landscapes, and waterways. Materials made with mushrooms, on the other hand, would be biodegradable and could be reused at the end of a product’s life to make more of the same stuff.

Much of researchers’ and journalists’ concerns about the new AI wave have focused on bots’ potential to generate bad answers and misinformation — and its potential to displace human workers. But David Gunkel, a professor of communication studies at Northern Illinois University, is wrestling with a different question: What rights should robots, including AI chatbots, have?

From the article

“This is a really important question because as soon as you mobilize the word “rights,” people immediately jump to “he must be talking about human rights and giving human rights to robots. This sounds absurd.” And it is, in fact, absurd because we’re not talking about human rights. When we talk about rights, we’re talking about social recognitions that can be either designated in terms of moral philosophy or in terms of law.” - Professor David Gunkel

Lunar astronauts might have to get their overalls ready, because the Moon could be the next great frontier for agriculture. The European Space Agency and Norwegian lunar agriculture company Solsys Mining have teamed up on a project to study how lunar soil could be used to produce fertilizer.

The project builds upon prior research demonstrating that plants can grow in lunar soil, albeit not very well. One of the main challenges is that lunar regolith lacks certain amounts of nitrogen compounds—a key ingredient in soil that allows flora to flourish. Another issue is that lunar soil gets tightly compact when wet, which creates trouble for plants trying to put down healthy and strong roots.

In parts of California that are ravaged by wildfire, disaster victims will vie against millions of other state residents for apartments in the state’s turbulent housing market. In cities like Miami and Norfolk, where sea levels are rising, homeowners may watch their homes lose value as the market shies away from flood-prone areas.

The first commercial spiral-welded 89-meter wind turbine tower has begun operation, built by GE Renewable Energy and wind turbine producer Keystone Tower Systems.

Spiral welding is when the steel used to make the tower is curled into a cylinder; essentially, these towers are built from meters-wide steel plates. The technique requires only one machine to construct a tower section, and it can produce towers up to twice as tall and 10 times faster than conventional towers.

The manufacturing process uses coil steel – flat-rolled steel that’s been coiled up into a roll or coil shape and allows tapered towers with variable wall thickness to be manufactured from constant width sheets of steel.

The manufacturing equipment completes the joining, rolling, fit-up, welding, and severing of a tower section – and that results in the continuous production of steel tower shells:

Keystone says it can make the lightest, lowest-cost, and most structurally optimized towers in the wind turbine industry.

Keystone is also developing mobile factories capable of building taller towers directly at wind sites.

Production is now being ramped up of spiral-welded towers, with additional deliveries targeted for the first quarter of 2023. They’ll make more towers for the GE 2.8-127 turbine, and they can be used interchangeably with GE’s conventional 89-meter-tall tower. The spiral tower has received a component certification from TÜV NORD for a 40-year lifetime.

See a video about the process here.

Building towers 10x faster, cheaper and onsite should mean a much-increased onshore wind turbine installation capacity, speeding the transition to renewable energy.

>A new generation of artificial intelligence is rolling out across American workplaces and it is prompting a power struggle between humans and machines.
>
>Recent advances in technologies such as ChatGPT, natural-language processing and biometrics, along with the availability of huge amounts of data to train algorithms, has accelerated efforts to automate some jobs entirely, from pilots and welders to cashiers and food servers. McKinsey & Co. estimates that 25% of work activities in the U.S. across all occupations could be automated by 2030.
>
>Today, however, AI’s biggest impact comes from changing the jobs rather than replacing them. “I don’t see a job apocalypse being imminent. I do see a massive restructuring and reorganization—and job quality is an issue,” said Erik Brynjolfsson, director of the Stanford Digital Economy Lab. McKinsey estimates 60% of the 800 occupations listed by the Bureau of Labor Statistics could see a third of their activities automated over the coming decades.
>
>For workers, the technology promises to eliminate the drudgery of dull, repetitive tasks such as data processing and password resets, while synthesizing huge amounts of information that can be accessed instantly.
>
>But when AI handles the simple stuff, say labor experts, academics and workers, humans are often left with more complex, intense workloads. When algorithms assume more human decision-making, workers with advanced skills and years of experience can find their roles diminished. And when AI is used to score human behaviors and emotions, employees say the technology isn’t reliable and is vulnerable to bias.

The following submission statement was provided by /u/esprit-de-lescalier:

The interference pattern is a supremely strange result because it implies that both of the particle’s possible paths through the barrier have a physical reality.

The path integral assumes this is how particles behave even when there are no barriers or slits around. First, imagine cutting a third slit in the barrier. The interference pattern on the far wall will shift to reflect the new possible route. Now keep cutting slits until the barrier is nothing but slits. Finally, fill in the rest of space with all-slit “barriers.” A particle fired into this space takes, in some sense, all routes through all slits to the far wall — even bizarre routes with looping detours. And somehow, when summed correctly, all those options add up to what you’d expect if there are no barriers: a single bright spot on the far wall.

It’s a radical view of quantum behavior that many physicists take seriously. “I consider it completely real,” said Richard MacKenzie, a physicist at the University of Montreal.

But how can an infinite number of curving paths add up to a single straight line? Feynman’s scheme, roughly speaking, is to take each path, calculate its action (the time and energy required to traverse the path), and from that get a number called an amplitude, which tells you how likely a particle is to travel that path. Then you sum up all the amplitudes to get the total amplitude for a particle going from here to there — an integral of all paths.

Naïvely, swerving paths look just as likely as straight ones, because the amplitude for any individual path has the same size. Crucially, though, amplitudes are complex numbers. While real numbers mark points on a line, complex numbers act like arrows. The arrows point in different directions for different paths. And two arrows pointing away from each other sum to zero.

The upshot is that, for a particle traveling through space, the amplitudes of more or less straight paths all point essentially in the same direction, amplifying each other. But the amplitudes of winding paths point every which way, so these paths work against each other. Only the straight-line path remains, demonstrating how the single classical path of least action emerges from unending quantum options.

Feynman showed that his path integral is equivalent to Schrödinger’s equation. The benefit of Feynman’s method is a more intuitive prescription for how to deal with the quantum world: Sum up all the possibilities. Sum of All Ripples

Physicists soon came to understand particles as excitations in quantum fields — entities that fill space with values at every point. Where a particle might move from place to place along different paths, a field might ripple here and there in different ways.

Fortunately, the path integral works for quantum fields, too. “It’s obvious what to do,” said Gerald Dunne, a particle physicist at the University of Connecticut. “Instead of summing over all paths, you sum over all configurations of your fields.” You identify the field’s initial and final arrangements, then consider every possible history that links them.

Feynman himself leaned on the path integral to develop a quantum theory of the electromagnetic field in 1949. Others would work out how to calculate actions and amplitudes for fields representing other forces and particles. When modern physicists predict the outcome of a collision at the Large Hadron Collider in Europe, the path integral underlies many of their computations. The gift shop there even sells a coffee mug displaying an equation that can be used to calculate the path integral’s key ingredient: the action of the known quantum fields.

“It’s absolutely fundamental to quantum physics,” Dunne said.

Despite its triumph in physics, the path integral makes mathematicians queasy. Even a simple particle moving through space has infinitely many possible paths. Fields are worse, with values that can change in infinitely many ways in infinitely many places. Physicists have clever techniques for coping with the teetering tower of infinities, but mathematicians argue that the integral was never designed to operate in such an infinite environment.

“It’s like black magic,” said Yen Chin Ong, a theoretical physicist at Yangzhou University in China who has a background in mathematics. “Mathematicians are not comfortable working with things where it’s not clear what’s going on.”

Yet it gets results that are beyond dispute. Physicists have even managed to estimate the path integral for the strong force, the extraordinarily complex interaction that holds together particles in atomic nuclei. They used two main hacks to do this. First, they made time an imaginary number, a strange trick that turns amplitudes into real numbers. Then they approximated the infinite space-time continuum as a finite grid. Practitioners of this “lattice” quantum field theory approach can use the path integral to calculate properties of protons and other particles that feel the strong force, overcoming rickety mathematics to get solid answers that match experiments.

“To someone like me in particle physics,” Dunne said, “that’s the proof that the thing works.” Space-Time = The Sum of What?

The greatest mystery in fundamental physics, however, sits beyond experimental reach. Physicists wish to understand the quantum origin of the force of gravity. In 1915, Albert Einstein recast gravity as the result of curves in the fabric of space and time. His theory revealed that the length of a measuring stick and the tick of a clock change from place to place — that space-time is a malleable field, in other words. Other fields have a quantum nature, so most physicists expect that space-time should too, and that the path integral should capture that behavior.

Efforts to increase productivity hold lessons for sceptics, too

If Liz Truss can compress a whole premiership into seven weeks, why can’t a standard working week be squashed into something more compact? A six-month pilot scheme, in which around 3,300 workers from 70 companies are testing out a four-day workweek, is due to conclude this month. Proponents say a shorter week delivers a better work-life balance without hurting overall output. Like previous such experiments, it is likely to be hailed a success. A mid-point survey by the trial’s organisers—researchers at the universities of Oxford and Cambridge and Boston College, the 4 Day Week Campaign, a non-profit, and Autonomy, a British think-tank—found that the transition had worked well for 88% of surveyed companies.

Sceptics might observe that the companies involved are self-selecting. Roughly one in five employers who had signed up dropped out before the pilot began, according to the 4 Day Week Campaign. Most of the participants that remain are smaller companies, many of them agencies specialising in management and technology. They also include charities.

But the scheme holds useful lessons about productivity. In particular a four-day week forces firms to think harder about time management. Most businesses in the trial have encouraged employees to leave meetings when they are not contributing, and to be more selective about accepting invitations. Daryl Hine of Stellar, an asset-management company in London, calls this a “diary detox”. This also extends to reducing commutes.

Of the participating organisations, 46% reported maintaining overall output at the same level, and 49% said it had improved. The trial’s largest company, Outcomes First Group, a children’s education and care provider, tracks indicators for its 1,027 participating employees. Its hr department has goals for response time to emails; it staff are given so-called net promoter scores, which track how colleagues rate their services. On both counts, they have made “rare” leaps, says Sharon Platts, the company’s chief people officer. Participants say that their employees feel more motivated. Plenty use the extra day to get errands out of the way before the weekend.

Becoming a four-day operation can be hard in a five-day world, however. Bookishly, an online shop, chose Wednesdays off to avoid having three days in a row when packages are not mailed out; people are warned about the new schedule before they order. But customers are not always prepared to wait, so most firms in the scheme have tried to spread staff more thinly. Platten’s, a fish-and-chip shop in Norfolk, gives its 50-or-so employees two days on and two days off to cover the week. Shifts overlap at busy periods, but organising training and team events has become trickier as a result.

More tests are on the horizon. In January South Cambridgeshire District Council will become the first British local authority to try out a four-day week. The lessons learned are likely to be valuable even if the idea does not spread. Mr Hine says that if performance slips, “gift days” will be rolled back. In busier periods employees may need to come in more. But in one way or another, he says, a slimmer work schedule is “here to stay”. ■7

A stem cell transplant has cured a man of HIV, researchers have announced.

The Dusseldorf Patient, 53, is only the third person to be cured of the condition using the treatment.

He appears to be the fifth person in total to be cured overall.

He had not taken anti-retroviral medicine, or suppressants, for four years and has not relapsed.

Similar to the other two patients - one in Berlin and another in London), the man, in Dusseldorf, had the transplant to treat a blood disorder, which in his case was leukaemia, that had developed alongside the HIV infection.

More than 10 years after the transplant and four years after ending his HIV therapy, he is in good health.

"I still remember very well the sentence of my family doctor: 'Don't take it so hard. We will experience together that HIV can be cured'," he said.

"At the time, I dismissed the statement as an alibi. Today, I am all the more proud of my worldwide team of doctors who succeeded in curing me of HIV - and at the same time, of course, of leukaemia.

"On Valentine's Day this year, I celebrated the 10th anniversary of my bone marrow transplant in a big way. My bone marrow donor was present as a guest of honour."

Researchers say the virus not returning is the result of thorough scientific and therapeutic preparation and monitoring, adding the study is the longest and most precise diagnostic monitoring of a patient following a stem cell transplantation.

A transplant destroys any unhealthy blood cells and replaces them with healthy ones removed from blood or bone marrow, and due to their high risk, are only carried out within the framework of treating other life-threatening conditions.

The team, which is led by medics at Dusseldorf University Hospital, hope the information they have gained will help more studies into cures for HIV.

Research should now be continued, experts suggest, to help HIV patients overcome infections without the need for this kind of strenuous intervention in the future.

The Dusseldorf Patient was diagnosed with acute myeloid leukaemia (AML), a form of life-threatening blood cancer, six months after starting his HIV therapy, and underwent the stem cell transplant in 2013.

Then, in 2018, after planning and constant monitoring by doctors, the anti-viral HIV therapy - which had ensured any residual HIV was kept under control up to that point - was ended.

On behalf of the international team, Dr Bjorn-Erik Ole Jensen said: "Following our intensive research, we can now confirm that it is fundamentally possible to prevent the replication of HIV on a sustainable basis by combining two key methods.

"On the one hand, we have the extensive depletion of the virus reservoir in long-lived immune cells, and on the other hand, the transfer of HIV resistance from the donor immune system to the recipient, ensuring that the virus has no chance to spread again.

"Further research is now needed into how this can be made possible outside the narrow set of framework conditions we have described."

The Nature Medicine journal has published the study.

In recent years, a man from California has been cured of the condition after his diagnosis in 1988, while Timothy Ray Brown, known as the Berlin Patient, was cured in 2007 - but later died from cancer.
