Coal Continues Collapse

One of the worst ways to generate electricity is to burn coal to heat water to spin turbines, the only reason this power generation exists is due to the cheap cost of coal. OF course, when coal is brunt it releases radiation and carbon into the atmosphere worsening local areas and the planet. Thankfully the use of coal is decreasing in totality around the world. This past year the USA produced more power from renewable sources than coal, which is a step in the right direction. Ideally the nation will ge their coal use to zero.

According to the Energy Information Administration, a federal statistical agency, combined wind and solar generation increased from 12 percent of national power production in 2021 to 14 percent in 2022. Hydropower, biomass, and geothermal added another 7 percent — for a total share of 21 percent renewables last year. The figure narrowly exceeded coal’s 20 percent share of electricity generation, which fell from 23 percent in 2021.

The growth in renewable electricity was largely driven by a surge in added wind and solar capacity, the agency said. Texas was the top wind-generating state last year, producing more than a quarter of all U.S. wind generation. It was also the leading state for natural gas and coal power. Iowa and Oklahoma landed at second and third in wind generation, accounting for 10 percent and 9 percent of national wind power respectively.

Tokyo Demonstrates the True Cost of Cars

Japan’s well respected car industry sells cars the world over, but at home it’s a different story. Car ownership is low in Japan for obvious reasons like having a good public transit system and high speed trains for intercity travel. In the capital city of Tokyo car ownership is amongst the lowest in the world thanks to the cost of owning a car itself. Tokyo’s lack of cars all comes down to refusing to buckle to the influence of large automobile companies.

Yet the much bigger reason for Tokyo’s high quality of life is that Japan does not subsidize car ownership in the way other countries do. In fact, owning a car in Tokyo is rather difficult. For one thing, cars are far more enthusiastically inspected than in America or most of Europe. Cars must be checked by officials every two years to ensure that they are still compliant, and have not been modified. That is true in Britain too, but the cost is higher than what a Ministry of Transport test costs. Even a well-maintained car can cost 100,000 yen to inspect (or around $850). On cars that are older than 10 years, the fees escalate dramatically, which helps to explain why so many Japanese sell their cars relatively quickly, and so many of them end up in East Africa or Southeast Asia. On top of that there is an annual automobile tax of up to 50,000 yen, as well as a 5 percent tax on the purchase. And then gasoline is taxed too, meaning it costs around 160 yen per liter, or about $6 a gallon, less than in much of Europe, but more than Americans accept.

Machine Learning Improves Enzyme Eating Plastic

A bacteria that eats plastic may sound too good to be true since we have so much plastic waste littering the planet. The rouble with plastic eating bacterias is that they aren’t efficient nor can they survive long outside the lab. So a research team turned to machine learning, or AI, to create a new enzyme that helps bacteria break down plastic. Of course, the best approach to eliminating plastic waste is not to use plastic in the first place.

Here’s the abstract:

Plastic waste poses an ecological challenge and enzymatic degradation offers one, potentially green and scalable, route for polyesters waste recycling. Poly(ethylene terephthalate) (PET) accounts for 12% of global solid waste, and a circular carbon economy for PET is theoretically attainable through rapid enzymatic depolymerization followed by repolymerization or conversion/valorization into other products. Application of PET hydrolases, however, has been hampered by their lack of robustness to pH and temperature ranges, slow reaction rates and inability to directly use untreated postconsumer plastics11. Here, we use a structure-based, machine learning algorithm to engineer a robust and active PET hydrolase. Our mutant and scaffold combination (FAST-PETase: functional, active, stable and tolerant PETase) contains five mutations compared to wild-type PETase (N233K/R224Q/S121E from prediction and D186H/R280A from scaffold) and shows superior PET-hydrolytic activity relative to both wild-type and engineered alternatives12 between 30 and 50?°C and a range of pH levels. We demonstrate that untreated, postconsumer-PET from 51 different thermoformed products can all be almost completely degraded by FAST-PETase in 1?week. FAST-PETase can also depolymerize untreated, amorphous portions of a commercial water bottle and an entire thermally pretreated water bottle at 50?ºC. Finally, we demonstrate a closed-loop PET recycling process by using FAST-PETase and resynthesizing PET from the recovered monomers. Collectively, our results demonstrate a viable route for enzymatic plastic recycling at the industrial scale.

You Won’t Regret Not Having Kids

kids

People with kids put a lot of pressure on couples without kids to procreate, which is obviously rude but happens anyway. This could lead to people thinking they want kids when really they don’t. In some places there is even social stigma around not having a child.

If you’re in the no kid camp then good for you! Don’t listen to the parents justifying their life decisions to make more of themselves. Indeed, you will not regret your decision to not have children later on. So go ahead and live the life you want to live.

Childfree individuals, who are also described as ‘childless by choice’ or ‘voluntarily childless’, have decided they do not want biological or adopted children. This is an important population to understand because its members have unique reproductive health and end-of-life needs, and they encounter challenges managing work-life balance and with stereotypes. Prior estimates of childfree adults’ prevalence in the United States, their age of decision, and interpersonal warmth judgements have varied widely over time and by study design. To clarify these characteristics of the contemporary childfree population, we conduct a pre-registered direct replication of a recent population-representative study. All estimates concerning childfree adults replicate, boosting confidence in earlier conclusions that childfree people are numerous and decide early in life, and that parents exhibit strong in-group favoritism while childfree adults do not.

Focus: Multitasking is a Myth


Think you’re bad at multitasking? You probably are, and if you think you’re good at it, well, you’re probably bad at it too. So why do we think multitasking is something we can do and why do we praise people who can? It has partly to do with sexism. There is a myth that women are better than men at multitasking and it needs to end. At workplaces women are given more work than men for cultural reasons and then told that they like the additional work.
How we got here is not good, but the solutions are already on the table and ready to be implemented. It all comes down to acknowledging this working myth and providing time for people to focus.

“These are usually shorter-term assignments that need to be done quickly. Can you help with that, cover for me here — these tasks are the interrupters, as opposed to the work you’re hired to do and is longer term and requires that depth,” said Weingart, who co-wrote The No Club: Putting a Stop to Women’s Dead-End Work. “These tasks tend to be less tightly tied to the organization’s bottom line, and they tend to be behind the scenes and less visible. When you define it that way, it’s much more than office housework or taking notes or getting the birthday cake.”
…
Now, after years of leaning into multitasking, many women are realizing that doing simultaneous tasks isn’t part of the promotion track. It’s the path to burnout. This awareness is the start of helping “women step back and figure out how to improve,” says Weingart.

Before committing to a task, Weingart suggests determining whether it’s of high value to your organization. If you still feel compelled to do it, try to understand your motivation for saying yes. Sometimes it’s guilt or fear of letting others down.
