If damage in the rDNA is not accurately repaired, it can lead to chromosomal rearrangements and cell death. In organisms from yeast to worms to humans, nucleoli expand during aging.

If damage in the rDNA is not accurately repaired, it can lead to chromosomal rearrangements and cell death. In organisms from yeast to worms to humans, nucleoli expand during aging.

Using sir2-mutant yeast (in which rDNA is replicated aberrantly early), Lichauco and colleagues systematically mutated known nucleosome-positioning enzymes and measured the relative timing of rDNA ...

AMD gave a brief preview of its next-gen Radeon RX 9070 and RDNA 4 architecture at CES 2025. One thing is clear: AI is a focus.

The latest AMD RDNA 4 leaks reveal that AMD may have changed its mind about the naming scheme, and they also give more insight into GPU performance.

AMD's David McAfee and Frank Azor have explained RDNA 4's absence from its CES press conference this year, and also spent a bit more time with us talking about its new "gamer-first" graphics card ...

These mother cells, which, in typical yeast fashion, would bud off to form daughter cells, were then monitored for levels of rDNA silencing (an indicator of nucleolus aging) and heme abundance (an ...

If damage in the rDNA is not accurately repaired, it can lead to chromosomal rearrangements and cell death. In organisms from yeast to worms to humans, nucleoli expand during aging.

Although AMD can rival most of Nvidia's graphics cards in pure performance, it always lagged behind in ray tracing. Are things about to improve?

AMD's new GPU can't even outperform Radeon RX 7900 XTX, says leak The best AMD RDNA 4 graphics card will reportedly be better at ray tracing than RDNA 3, but will still be slower than the current ...
