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 ...

While many of life's mysteries remain unsolved, every biologist can describe the basic processes performed by a living organism, including energy use, reproduction, growth and development. While these ...

Scientists built a synthetic cell that combines more lifelike properties than ever before — proof of concept that it’s possible to bring nonliving materials to life, or something close to it, in the ...

Their bodies and their genomes were built in the lab from scratch, each molecule specified precisely. According to John Glass ...
