One might think that many genes would have to be changed in order to extend our lifespans – genes affecting muscle strength, wrinkles, dementia, and so forth. But research on worms and mice has found something quite surprising: there are certain genes whose alteration can slow the aging of the whole animal all at once.
SAN FRANCISCO – Even if young people think they are immortal, they can’t help but notice how fast their pets age. The puppy we receive as a child is old by the time we reach adulthood. Why do we live longer than dogs? The answer must lie in our genes, because genes are ultimately what make us different from other animals.
Presumably, we live longer than dogs because, during the evolution of our common ancestor, gene changes occurred in our lineage that slowed our rate of aging. To find the genes that can influence aging, researchers have begun to change individual genes in specific animal species, hoping to copy some of what evolution has done so well.

As in the 1970s, a severe economic shock has forced governments to pursue massive fiscal and monetary expansion, thereby sowing fears of future inflation. But not all shocks are the same, and the key question now is whether we can be confident that the current state of exception will end.
show that the brewing debate about the threat of unanchored expectations is falling into a familiar pattern.
President Joe Biden’s administration appears determined to separate America's relationship with the Kingdom from the relationship with Crown Prince Mohammed bin Salman. But this separation will likely prove impossible to sustain.
explains why the Biden administration has no choice but to maintain ties with Crown Prince Mohammed bin Salman.
