Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device achieves long-term functionality without the continuous forcing mechanism that ...

What if the mechanical properties of a cell could be programmed like the components of a machine? Researchers at the ...

Silver nanoparticles provide a more efficient way to cut and assemble DNA, improving recovery rates and boosting DNA joining ...

A tiny set of ancient genetic “switches” may have played a surprisingly large role in making human language possible. Researchers found that these DNA regions, which act like volume controls for genes ...

How diseases develop and how the body ages can differ between females and males, but the biological reasons for these differences are not fully understood. Researchers are studying the role of sex ...

You can listen to more articles from The Conversation, narrated by Noa, here. Researchers at the University of Cambridge have developed what they describe as a fundamentally new type of vaccine using ...

Definition: A microarray is a small, flat substrate carrying an ordered grid of microscopic probe features, each containing a known biological molecule, that is used to measure many molecular targets ...

When we think about genetic inheritance, we usually leap to DNA, the four-letter code containing the instructions for building a living organism. Scientists know that DNA encodes everything from hair ...

Murder investigators in Arizona are encountering a stubborn obstacle to solving a decades-old cold case involving an unidentified dead body: The woman’s Ashkenazi Jewish DNA. In 1989, an unclothed ...

Maybe he was confused. Or scared. But the confession had to be true. Surely Christopher Barbour just got the name wrong and identified the wrong man who raped a Montgomery woman before Barbour stabbed ...

CRISPR Cas9 genome editing has transformed the way scientists approach gene therapy, acting like precise DNA scissors that can target and repair hereditary diseases at the genetic level. This ...

Scientists have uncovered a surprising secret about our DNA: it’s not a static blueprint, but a constantly shifting, folding structure that helps control how genes turn on and off. Researchers at the ...
