Scientists find 57,000 cells and 150m neural connections in tiny sample of human brain.

Harvard researchers teamed up with Google to analyse the makeup of the brain, much of which is not yet understood.

@ianRobinson One of my favourite facts is that a goldcrest is roughly a tenth the weight of a mouse, but has twice as many neurons in its brain.

@jgrg@mstdn.science avatar

@ianRobinson Scaling that up to a whole human brain, which is more than a litre, gives about 10¹⁴ connections!

This explains it. I started to hear it in chess streams featuring the Botez Sisters. And Alexandra Botez plays poker. https://mastodonapp.uk/@keefeglise/112263105374686140

@ianRobinson @keefeglise The phrase may have been adopted by poker players from the anti-tilting mechanism of pinball machines. When "on tilt" the machine lights up and the flippers are disabled so you can't do anything.

Bari Weiss's media company, which has pushed

  • Covid denialism
  • Railed against public health measures
  • Claimed women w invisible illnesses were suffering from "anxiety"

just launched a new health column written by Weiss's wife who has zero background in the health or science world

@taylorlorenz Weird that Vinay Prasad went off the rails like that over Covid. I thought he had sensible things to say when he was talking about overly expensive cancer drugs which have very little benefit to patients.

In the next 48 hours, Russia will lose its 10,000th artillery piece in Ukraine — on top of everything else, which has been obliterated in this war.

Imagine how great Russia could have been with a democratic government who spent these enormous resources on building a better country instead of destroying someone else's.

jgrg,
@jgrg@mstdn.science avatar

@randahl The Oryx blog has 10,000 destroyed pieces of heavy equipment. Artillery is more like 1000 losses. https://www.oryxspioenkop.com/2022/02/attack-on-europe-documenting-equipment.html

jgrg,
@jgrg@mstdn.science avatar

@richlv @randahl Indeed, but 10 times the Oryx losses doesn't seem credible. Two or three times seems possible, given that artillery is in the rear and less likely to be photographed. Maybe five times maximum.

@thomasfuchs @GossiTheDog It does. But it doesn't say what make of toothbrush it was, or what the Swiss website that was DDoS'd was. There are toothbrushes that can connect to a smartphone, presumably via Bluetooth, but I don't see how you could make a botnet out of them.

O'Leary's latest idea for Ryanair?

NO!

It's a rail firm that's pioneering stand-up seats (sounds like a contradiction, but the picture shows it)

These extra high capacity areas are in Regiojet's CRRC Chinese built EMUs that starting running in Czechia today

Here's a story - in Polish - about the launch: https://www.rynek-kolejowy.pl/wiadomosci/regiojet-rozpoczal-testowanie-chinskiego-pociagu-sirius--117273.html

Toying with a new project graph in that I find fascinating: the ratio between lines of code divided per number of lines of docs - in the git repository over the last 24 years.

The number of lines of code has increased more than 8x in this period, from less than 20K lines to over 160K lines.

@bagder What happened in May / June 2014? Did you have a documentation drive, or did you delete a load of code?

@mo8it @timClicks Might be a Panasonic camera that uses their DFD focusing system? A fix would be to leave it in manual focus mode, but that's awkward if you want to hold things up to the camera and have it autofocus on them.

jgrg,
@jgrg@mstdn.science avatar

@timClicks @mo8it I found this advice about the a6400: "Try shooting at f/8 or wider. At f/11 the camera switches to contrast detect AF which causes the pulsing in AF-C mode."

Mac revenue down, why? IMO because the M1 “”/Pro are too damn good.

Will the M3 fix things? I doubt it, the M3 Max is a ton better than the M1/M2 Pro/Max, but the machines most people can actually afford to buy aren't “got to buy it" faster.

jgrg,

@paul Yes. I think there was enormous pent-up demand for MacBooks from people who held out during the terrible butterfly keyboard and Touch Bar period, which is now satisfied.

Also apparently I deny fuel cell vehicles exist, despite having literally photographed one

@Hypx We do need a vast number of batteries for BEVs. You'll never beat their efficiency. We need to build a vast amount of electrolysis capacity we don't currently have to be able to soak up wasted wind power. We need that hydrogen for industrial processes that can't use electricity.

jgrg,
@jgrg@mstdn.science avatar

@Hypx I'm not wrong about efficiency. H₂ has big losses in both elecrolysis and in the fuel cell, and bigger losses in transportation of the fuel compared to electricity too. The gap is too big ever to be closed.
Fuel cells are also worse than batteries in theory. The maximum theoretical efficiency of a H₂ / air fuel cell is less than currently deployed batteries, which are are 85% efficient!

jgrg,
@jgrg@mstdn.science avatar

@Hypx Nonsense. It is as bad as I say. H₂ losses are way worse than electricity transmission and batteries.
And you're hypothesising future developments in H₂ compared to currently deployed battery technology.
