Over a few million years, the spider Dysdera tilosensis—a species endemic to the Canary Islands—has reduced the size of its ...

In 2001 the sequencing of the human genome revealed a surprising fact: over 45% of our genome comes from sequences called transposons, ‘jumping’ genes that can move within the genome, generating new ...

Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown.

CU Boulder researcher Edward Chuong recently received an international award for his lab’s work studying transposons in the human genome Our genome, it turns out, is full of freeloaders—selfish ...

Unstable anthocyanin3 (an3) alleles of petunia with insertions of the Activator/Dissociation-like transposon dTph1 fall into two classes that differ in their genetic behavior. Excision of the (single) ...

As CRISPR continues to drive breakthroughs in medicine, agriculture, and synthetic biology, understanding its origins does more than tell an ancient story. It provides a blueprint for engineering the ...

From the beginning of its history the Royal Society has devoted much attention to the publication of communications by its Fellows and others. Within three years from the granting of the first Charter ...

CRISPR-Cas systems are adaptive immune systems found in prokaryotes that defend against invading nucleic acids through CRISPR RNA-guided cleavage. Type V CRISPR-Cas (Cas12) systems, in particular, ...

Why does the COVID-19 virus make some people sicker than others? For years, scientists have looked to a critical piece of immune system machinery—known as the interferon pathway—for answers. There, ...
