Researchers: Importantly, we show that some archaeal histone variants are ancient and have been maintained as distinct units for hundreds of millions of years. Our work suggests that complex combinatorial chromatin that uses histones as its building blocks exists outside eukaryotes and that the ancestor of eukaryotes might have already had complex chromatin.
Back to Georges Lemaitre, a Catholic priest: A CENTURY ago, if you asked a cosmologist the universe’s age, the answer may well have been “infinite”. It was a neat way to sidestep the question of how it formed, and the idea had been enshrined in 1917 when Albert Einstein presented his model of a static Read More…
He seems to have started noticing recently when astrology was touted at the Guardian and the Globe and Mail: In the past couple of days we’ve seen the Guardian tout astrology twice, and now the Globe and Mail. What I’d forgotten is that the New York Times has also been doing it occasionally—certainly more often Read More…
Here’s a scenario for your consideration: Suppose there were a group of people who insisted there is absolutely no objective standard for morality and that all moral norms are based on subjective preferences that are foisted on us by material evolutionary forces. And suppose there were a group of people who are so serenely confident Read More…
We were told it was the surest thing in origin of life theories.
A very reasonable question: “Is The Flintstones a more accurate picture of Neandertals than evolutionary documentaries?”
Well, from a novelist’s perspective, it sounds logical but from a science perspective, if you must invoke the “multiverse,” you are in trouble.
Even if you don’t believe in God, can you at least believe that 2+2=4? That puts you on one side of a growing cultural divide.
At Smithsonian: Every so often the adult footprints pause and are joined by a child’s footprints. The footprints go in a straight and definite line, and pretty fast, indicating a deliberate end target; they then return in the opposite direction, this time without the child.
If it were not rigorously pounded out of you by a pop science education, you’d almost think that human intelligence has something to with longevity…
Move along, folks. No design to see here.
Researchers: The researchers have found that female sex hormones instruct important changes in the thymus, a central organ of the immune system, to produce specialized cells called Tregs to deal with physiological changes that arise in pregnancy.
Now at last, courtesy a science preprint, we have a name that makes sense to us. The “irreducible complexity community” — the ICs.
Classically, it shouldn’t have happened.
Hilditch: It turns out that religiosity is usually determined very early in life. All the data suggest that, by and large, kids brought up in religious households stay religious and kids who aren’t, don’t.
