Why do you hate your books?

Sorry. I was referring to Carl's article. The Science site seems to be down.

Hmm. The article seems to be assuming that all matings between male Neanderthals and female modern humans were consensual, reflecting mating preferences. Wouldn't we see the same patterns if male Neanderthals frequently raped female modern humans?

See www.usefulgenetics.com and www.youtube.com/@UsefulGenet..., where Mendelian genetics is taught as a special case of pleiotropy and polygenicity.

Putting my money where my mouth is: the Useful Genetics project Two years ago, I jumped on the Massive Open Online Course (MOOC) bandwagon. I had just published a rant about the need to replace Mendelian genetic analysis with topics that were more useful to our st...

I did it, with Mendelian genetics as a special case of normal polygenic and pleiotropic inheritance - it works great. See 'Why do we have to learn this stuff"? (journals.plos.org/plosbiology/...) and 'Putting my money where my mouth is' (www.cell.com/trends/genet...

"The ancestors of bacteria must have been microbes that breathed oxygen," Should this read 'The ancestors of mitochondria..."?

The mitochondria in metabolically active cells would probably stop working within a few minutes. (Not as fast as from cyanide, but close). You'd be dead very quickly.

Life’s evil twins, called mirror cells, could wipe us out if scientists don’t stop them Researchers are close to making “reversed” cells that may wipe us off the planet

I wouldn't have expected this fearmongering from @vscooper.micropopbio.org www.scientificamerican.com/article/life.... Most of his arguments seem quite weak - for example, vertebrate immune systems should learn to recognize epitopes with flipped chirality as easily as any other epitope.

No, Carney didn't use a speechwriter. This speech is pure himself.

Davos LIVE: Canadian PM Mark Carney speaks at World Economic Forum YouTube video by Associated Press

I don't think I've ever listened to/read a full Davos WEF speech before but this speech by PMMC is something else. The discussion afterwards is good too. You should find some time to read/listen.

Or maybe it's because the cause of the advantage is easy for non-specialists to understand.

Nobody in Canada ever complains about symmetrical rounding, and we love not having to deal with pennies.

Typical physicist assuming that their world view is superior to everyone else's.

But many public libraries are happy to purchase books that their readers suggest, and they'll also help you find an interlibrary-loan copy.

I was a post-doc in Ham's group in the late 1980s. He was hands-off for his post-docs and hands-on at the bench - setting a wonderful example.

OK, I read the proposal, but now I need to read an explanation of what's wrong with it.

I think when the beetles first invade they build to high densities and the crows learn to feast on them. In later years the damage done by crows decreases, perhaps because the larvae are now being limited by pathogens and parasites.

I think they hear them crunching on the grass roots. It's easy for them to pull up the clumps of sod because the larvae have destroyed the roots.

I've always said that most scientists spend most of their time trying to figure out why their experiments don't work. If you don't really enjoy troubleshooting, don't go into scientific research.

Vancouver: Several in Stanley Park, a big cluster at UBC, one at Jericho Beach, but none on the south and east sides of the city. Must be recreation-related?

Drat, that's not a very large effect of COVID vaccination. I knew that protection waned after a few months, but I expected the initial effect to be much larger.
