I'm a big fan of the period between Christmas and when most of the world gets back to work in the New Year. It's the only time of year that I know of where the email firehose shuts off, the social permission to do "nothing" turns on, and the world generally quiets down.
I know that not everyone gets this time off. We all have different jobs. Earlier in my career, I used to always work these days between Christmas and the New Year because I couldn't spare the vacation days. But if you are fortunate enough to have it off, it's a unique time of the year.
It's a time for family and friends, and a good time for vacations that aren't riddled with email and work anxiety. But it's also a time that creates space for the mind to wander, and for me, it gives me a creative burst of energy.
I've been trying to think of the best way to describe this feeling, and it truly feels like "mental space." When work is "on," it simply crowds out everything else. But a more accurate neuroscientific definition would be that we're simply engaging different parts of our brains.
Supposedly, when the mind is given "space" to wander — which is also referred to as wakeful rest — we engage a system in our brain known as the Default Mode Network. This network is thought to serve several different functions, including forming the basis for the self, thinking about others, remembering past events, and imagining possible future events. Generally, this makes it very good at connecting the dots, so to speak.
The counterpart network is our Executive Control Network. This part of our brain is most active during focused, demanding, and goal-oriented tasks — so work.
These two networks are also thought to be inversely correlated, meaning when one activates, the other often shuts down. But not always and not entirely. A 2018 research article by Roger E. Beaty et al. found that highly creative people have a unique brain "wiring" that allows these different neural networks to work together, rather than in opposition.
What this suggests to me, as a cognitive neuroscience layperson, is that engaging our different brain networks is good for us. Sometimes it's good to turn down executive control and give some space to default mode.
And I find that this time of year is a perfect time to do just that.

I like thinking about new things, and so I like this recent post by Vitalik (the Ethereum crypto guy) talking about what he calls "the tree ring model of culture and politics." The basic insight of the model is the following:
How a culture treats new things is a product of the attitudes and incentives prevalent in that culture at that particular time.
How a culture treats old things is primarily driven by status quo bias.
To explain why the world seems to work like this, he uses the analogy of tree rings, which are also called annual rings or growth rings. Trees grow in diameter each year and the result is a set of successive rings.
Importantly, each tree ring is a result of the conditions that the tree experienced during its growing season. A wide ring typically suggests a favorable growing season and a narrow ring suggests a stressful growing season.
Once the growing season is over, the ring becomes set, which is why dendrochronology is a thing, and why tree rings can be used to tell us about what happened in the past.
The parallel with culture and politics is that it's far easier to shape new things during their initial growth cycle, then to try and do it later. Because once the growth cycle is over and it becomes an old thing, attitudes are then guided by the status quo. They become set.
To quote Vitalik: "What is easier is to invent new patterns of behavior that outcompete the old, and work to maximize the chance that we get good norms around those." This makes a lot of sense to me and it's a reminder to stay open to new things.

By some measurements, cement production alone is responsible for about 8% of human-caused carbon dioxide emissions every year. And so there is an imperative to find suitable low-carbon alternatives. Here is what is currently happening in the US (via Grist):
On Tuesday, Terra CO2 Technology was picked to receive a $52.6 million federal grant to build a new manufacturing plant just west of Salt Lake City. The company has devised a method that turns common minerals into additives that can help replace Portland cement — a key component in concrete, and one of the most carbon-intensive materials in the world.
In addition to this new facility, the company is set to start construction on its first plant in the Dallas-Fort Worth area:
The project is expected to break ground in January 2025 and begin shipping out materials by late summer 2026, Yearsley said. The facility will be capable of producing up to 240,000 metric tons of SCM [supplementary cementitious materials] per year when completed, or enough to serve roughly half of the local metropolitan market.
And all of this is part of a broader initiative by the US Department of Energy:
The Utah facility is one of 14 projects provisionally selected this week to receive $428 million in total awards from the U.S. Department of Energy’s Office of Manufacturing and Energy Supply Chains. The initiative, which is funded by the Bipartisan Infrastructure Law, aims to accelerate clean energy manufacturing in U.S. communities with decommissioned coal facilities. Officials said the projects are expected to create over 1,900 high-quality jobs across a dozen states.
