At least it's not a conspiracy!
That would be lemurs.
Actually the previous owner here had small children and installed iron gratings on all windows to prevent the possibility of the children having a nasty accident so the crows would just kill themselves against the window. I wouldn't even need to stone them.
You can say a flight of birds if you prefer, in the interests of clarity, but I've just been struck by the phrase ‘Sheeps of a feather flock together’ as excellent wit.

Well, they are a rather negative bunch.

Actually, crows are very intelligent, and although I had an ongoing fight with a bunch of magpies back in 1993 (they kept stealing the food I put out for the feral kitten I was trying to catch), I will admit that they are beautiful birds.
TIL about Manhattanhenge when setting or rising sun is aligned perfectly with east-west streets of the main street grid of Manhattan. Setting sun alignment is today (11th July) at 8:30 PM EDT.

Today I learned that orange pill bottles prevent ultraviolet light from wrecking pills that are sensitive to it.

Did aimee's quoted story mis-spell his name then? Should it be "Rybczynski" not "Rybcyznski"?
Yeah, still, and it sucks.
Epic. I always believed in Heyerdahl.
Strangely, this little bit of news made my day.
Thank you.
Heyerdahl thought that Native Americans traveled to Polynesia on rafts. The new research says that Polynesians traveled to SA in outrigger canoes. Not the same at all.Epic. I always believed in Heyerdahl.

It does not seem that clear:
Our earliest estimated date of contact is ad 1150 for Fatu Hiva, South Marquesas. This is close to the date estimated by radiocarbon dating for settlement of that island group, raising the intriguing possibility that, upon their arrival, Polynesian settlers encountered a small, already established, Native American population. It was on the island of Fatu Hiva—the easternmost island in equatorial Polynesia—that Thor Heyerdahl hypothesized that Native American and Polynesian individuals might have contacted one another, based on islanders’ legends stating that their forefathers had come from the east. The Marquesas lie at the latitude of Ecuador, and wind- and current-based simulations indicate that
they are the islands most likely to be reached from South America via the strong east-to-west currents and winds at these equatorial latitudes.
We cannot discount an alternative explanation: a group of Polynesian people voyaged to northern South America and returned together with some Native American individuals, or with Native American admixture, as speculated in ref. 10. We have dated the contact event to the time when Polynesian explorers were, according to some studies, making their longest-range voyages (the century surrounding ad 1200)—a time when these studies suggest that the Polynesian settlers discovered all remaining island groups in the Pacific, from Hawaii to New Zealand to Rapa Nui. The Tuamotu Archipelago, which lies at the centre of the Polynesian islands in which we found a Native American component,
is known to have been a Polynesian voyaging hub, and according to simulations it is the second most likely location to be reached when voyaging from South America. Further population genetics collaborations with these genetically understudied island populations are needed to resolve these alternative hypotheses.

Yesterday I learned that Ian Fleming, the author of James Bond, actually worked as intelligence officer during World War II https://en.wikipedia.org/wiki/Ian_Fleming#Second_World_War .
Perhaps. But the Polynesians are the ones with a long history of ocean sailing. If there was a NA settlement (or settlers) on Fatu Hiva, I think that Polynesians made it possible for them to get there.
It's Rybczyński, with a ´ on the n, in fact.

So they knocked out the patients hematopoietic cells, then gave them a healthy persons umbilical cord blood. It resulted in 90% of their blood cells being from the donor. 95% lived to a year, 85% to five years. It is impressive and all, but one example of diseases treated is sickle cell (3 of 44 patients) and over 99% of those with SCD born in the UK will survive to adulthood and mean life expectancy is in the 60s.
I wonder how the immune system learns self in this case.

Not so fast there, buddy! The article I cited isn't beyond criticism.
Some think that there are big holes in some of their arguments. As big as those in many of Thor Heyerdahl's theories, I'd say.
Did ancient Americans settle in Polynesia? The evidence doesn’t stack up

TIL Ants do things I had not known they do. We have found little piles of dirt and gravel on our back patio in recent days. They built them on top of solid stone or concrete without direct access to any underlying dirt.
So I explored one of them this morning and found this:
They are burying dead lizards caught and killed by our cats. You can see it's head. The ants leave a small tunnel into the mound, I guess so they can continue to collect food. The mound keeps other critters away and keeps the lizard from getting too dry to be useful.
