Abnormal RNA gums up the works in brain cells, shows study

Our DNA contains four types of molecules, adenine, cytosine, thymine, and guanine—called nucleotides or bases—running along the strands that make up our chromosomes. Since there are only four, it is not unusual to find ...

Modified nucleotides used in COVID-19 vaccines work as designed

The remarkable effectiveness of mRNA vaccines against SARS-CoV-2 has generated much interest in synthetic mRNA therapeutics for treating and preventing disease. But some basic science questions have remained about whether ...

Study of Arctic fishes reveals the birth of a gene—from 'junk'

Though separated by a world of ocean, and unrelated to each other, two fish groups—one in the Arctic, the other in the Antarctic—share a surprising survival strategy: They both have evolved the ability to produce the ...

The cartography of the nucleus

Nestled deep in each of your cells is what seems like a magic trick: Six feet of DNA is packaged into a tiny space 50 times smaller than the width of a human hair. Like a long, thin string of genetic spaghetti, this DNA blueprint ...

Two studies find stress reprograms cells

In a pair of publications, researchers have shown how cells adapt to stressors—like water loss—by reprogramming their internal signaling networks. The studies describe previously unknown mechanisms that cells use to send ...
