Climate Change Makes Robowrapper More Than Just Fashion

I don't know about you, but I'm ok wearing a spacesuit while still on Earth, as long as it has air conditioning. And persistent surveillance of my health data, of course. 

Not that I want to, but I'm ok with it. And I'm not talking Apollo marshmallow man spacesuit. This suit is actually integrated into your own skin. At some point, it will be hard to distinguish between our clothes and our skin. To "wear" something will have a different meaning, and you won't be able to function without a nano-networked-supercomputer covering your entire body (never mind not being able to live without an air-conditioned bodysuit simply because it's too hot).

Researchers create powerful unipolar carbon nanotube muscles

"Electrochemically driven carbon nanotube (CNT) muscles" sound like a morph suit that's also an exoskeleton.

The system contained a flexible sweat extraction process to noninvasively extract and fingerprint analytes inside the body based on their unique Raman scattering spectra. 
Light-emitting tattoo engineered for the first time
Feb 2021, phys.org
The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos. That is, the OLEDs are fabricated on to temporary tattoo paper and transferred to a new surface by being pressed on to it and dabbed with water. ... could be combined with other tattoo electronics to, for instance emit light when an athlete is dehydrated, or when we need to get out of the sun to avoid sunburn. OLEDs could be tattooed on packaging or fruit to signal when a product has passed its expiry date or will soon become inedible, or used for fashion in the form of glowing tattoos.

Researchers find space station's surface microbial profile resembles skin of its crew members

We will be the spaceship. It will become our bodies, rather, our bodies will become a ship.

Fungal ghosts protect skin, fabric from toxins, radiation
Mar 2021, phys.org

There's a fungus that naturally makes melanin, which is protective against ultraviolet radiation, and so they grow the melanin, then etch away the fungus, leaving only the melanin cell. The leftovers are called fungal ghosts, and can become a kind of artificial skin. And also for, you know, "potential for applications in long distance space flight."

Silicon vs Carbon and the Battle for Human Cognition


Apr 2020, phys.org

As a person who uses carbon dioxide levels to estimate indoor air quality, this projection is hard to believe -- Carbon dioxide levels are predicted to rise to almost 1,000 parts per million (ppm) by the year 2100, with indoor accumulation at 1,400 ppm.

It's hard to believe because today it's 400ppm outside. In 1900ish, it was 300ppm. But because we exhale carbon dioxide, it accumulates in spaces with poor ventilation. Today, if CO2 reaches 1,000ppm, we say there's something wrong with your ventilation system. In 2100, the entire planet will have a "ventilation problem," at least from the perspective of an oxygen-breathing meatbag.

To be exposed to that much CO2 all the time will lower your IQ. It's not just 8 hours a day, it would be all day all night of exposure:
Put simply, when we breathe air with high CO2 levels, the CO2 levels in our blood rise, reducing the amount of oxygen that reaches our brains. Studies show that this can increase sleepiness and anxiety, and impair cognitive function.

In fact, at 1,400 ppm, CO2 concentrations may cut our basic decision-making ability by 25 percent, and complex strategic thinking by around 50 percent, the authors found.

Kristopher B. Karnauskas et al, Fossil fuel combustion is driving indoor CO2 toward levels harmful to human cognition, GeoHealth (2020). DOI: 10.1029/2019GH000237
Luckily, we're already doing something about this.

No, not like that. We aren't going to reduce the amount of CO2 in the air. We're making artificial brains to take over where our environmentally-sensitive brains leave off. Every year, as the CO2 rises, we will offload more and more of our oxygen-intensive decision making to silicon brains. They don't need oxygen. Eventually, neither will we.
