Scientists Catch Jumping Genes Rewiring Genomes
Transcription factors that act throughout the genome can arise from mashups of transposable elements inserted into established genes.
DNA’s Histone Spools Hint at How Complex Cells Evolved
New work shows that histones, long treated as boring spools for DNA, sit at the center of the origin story of eukaryotes and continue to play important roles in evolution and disease.
Researchers Read the Sugary ‘Language’ on Cell Surfaces
Glycans, the complex sugars that stud cellular surfaces, are like a language that life uses to mediate vital interactions. Researchers are learning how to read their meaning.
A Backdoor Lets the Immune System Monitor the Brain
A newfound hub of immune system activity at the back of the brain solves a century-old puzzle.
DNA of Giant ‘Corpse Flower’ Parasite Surprises Biologists
The bizarre genome of the world’s most mysterious flowering plants shows how far parasites will go in stealing, deleting and duplicating DNA.
The Brain ‘Rotates’ Memories to Save Them From New Sensations
Some populations of neurons simultaneously process sensations and memories. New work shows how the brain rotates those representations to prevent interference.
New Genomic Study of Placenta Finds Deep Links to Cancer
A patchwork of genomic differences in the placenta may explain the organ’s “live fast, die young” strategy and its connections to cancer.
Cells Form Into ‘Xenobots’ on Their Own
Embryonic cells can self-assemble into new living forms that don’t resemble the bodies they usually generate, challenging old ideas of what defines an organism.
Chasing the Elusive Numbers That Define Epidemics
Most modeling efforts during the COVID-19 pandemic have sought to address urgent practical concerns. But some groups aim to bolster the theoretical underpinnings of that work instead.
