Bacteria can often synthesize all 20 amino acids themselves if they have enough carbon and nitrogen. They don't need to ingest existing amino acids from the environment.

If it makes you feel better, while someone with blindsight is able to interact with the objects in front of them through a subliminal awareness of them they can't form memories of those objects. Memory is actually very useful and cons

Well, the decode used to use 15% of an x86 core's power budget but it hasn't grown as fast as the other structures so I'd guess more like 10% these days. So you're losing out on being able to turn off a small but notice

A mere trillion years is a tiny fraction of the time it would take for a brain to form like this spontaneously. This concept arose when people generally thought the universe was in a generally steady state and had existed forever. Even th

During Covid the process chemists working on this, including my wife, and the group working on Remdesivir were the only ones not working from home at the Gilead's Edmonton facility.

ALLFED[1] is an organization doing research into how we could keep most everyone alive if we have a decade of winder after a super volcano, asteroid impact, or nuclear winter. Processes that convert hydrocarbons into calories are certainly

If you want conventional car utilization where the car sits in a parking spot most of the time then the extra cost from the lidars is much more of an issue than if you're operating a fleet that is acting as taxis most of the day.

Laser safety ratings are based on what would happen if the laser was pointed directly at your eye continuously. In the case of general traffic each lidar is scanning in different direction and while manufacturers try to make the energy pro

It might be the correct technical term, but general interest publications like Wired should avoid jargon that confuses laypeople, especially in headlines.

Generally you should trust science on matters of "is". But on matters of "ought" science only bears indirectly.

It's definitely something that's happened community by community. A lot of space news I care about is still just on Twitter but urbanism stuff has mostly moved to Bluesky, for instance.

99% of people are either better off using a language with a garbage collector or need to avoid heap allocations altogether.

It's the law that US hospitals have to provide care regardless of ability to pay in an emergency but not preventative care. Medicaid, which would cover dialysis for most poor people doesn't cover unauthorized immigrants. Your ho

The question itself if just semantics. But considering our mitochondria as evolving populations subject to selective pressure and genetic drift is really important to understanding their role in our health, down to basic questions like &qu

The first time it happened involved a huge number of changes in the host cell, like the creation of a nucleus. That makes it seem more likely that an already eukaryotic cell can more easily incorporate other endosymbiotes. Observation of p

It's more that cells can have large numbers of mitochondria than that teach produces a large amount of power. Prokaryotic cells can grow large, but because they respirate over their surface they are energy limited.

It has the advantage that the energy it gives off can be be converted directly to electrical energy rather than driving an external heat engine, so despite the greater difficulty of ignition its not obviously a worse choice.

And even ignoring the tones, how many foreigners can pronounce pinyin correctly? It takes a very different approach to representing non-Latin vowel sounds with Latin characters than English does, there's 'c' being pronounced

We should build more housing so that homes aren't such good investments that people are tempted to do this.

I tried to do the math once to figure out if Japan would have been better off building a coal power plant instead of Fukushima, the nuclear plant that had the worst disaster in any western country. It was a surprisingly tough question. ht

I'd say that (1) there's a lot more to the medieval period than just the high middle ages in England and France and (2) a world with orcs, owlbears, etc is going to tend to be more thinly populated than similar historical analogue

There are certainly certain categories of chemical that might be of interest. For instance you don't normally find emulsification agents in non-processed food but you do in industrial food, whether the particular chemical is made in a

In a previous version of the bill it was either that many flops or that much money. Now it's both.

It would be sort of cool if they could do direct to consumer sales with every core going at whatever its maximum speed is or turned off if to disrupted. But that's not something you could do through existing distribution channels, eve

There are still a lot of differences, even if you put in a lot more SIMD lanes to the CPU. CPUs keep their execution resources fed by by aggressive caching, prefetching, and out of order execution while GPUs rely on having lots of threads

If a consumer is conscientious enough to recycle something, the counterfactual is that they put it in the trash rather than that they throw it into the nearest river. In a landfill, a plastic bottle will lock up its constituent carbon for

The real danger with plastic is that it'll go to some under regulated recycler which picks out the 30% of plastic that it can recycle and then dumps the rest in the nearest river. If I put it in the trash in a modern country I can be

Lets say Fred makes $200k one year and saves $50k of it in stocks, CDs, or even his checking account. He pays taxes on his $150k consumption. The next year he splurges on something and spends his $200k salary and his $50k savings. He pay
