Motion control at the nanoscale

NUS Physicists have designed a bipedal nanowalker that can change its walking manner and direction by adjusting the length of its stride. Deoxyribonucleic acid (DNA)-based nanowalkers are a class of molecular motors which ...

CRISPR method for conditional gene regulation

A team of engineers at the University of Delaware has developed a method to use CRISPR/Cas9 technology to set off a cascade of activities in cells, a phenomenon known as conditional gene regulation. Their method, described ...

DNA research offers clues on cell mutation

A team of researchers from Colorado State University has been studying DNA damage in living cells to learn more about how genetic abnormalities arise. It has long been known that DNA molecules in every cell get constantly ...

Study describes revolutionary method of making RNAs

A biochemist from The University of Texas Health Science Center at San Antonio is a co-author on a paper in Nature that describes a new, more efficient method of making ribonucleic acids (RNAs).

Is eating DNA safe?

Eating DNA sounds scary but it's completely safe. I do it every day. Let me explain.

Microbiologists find source of fungus's damaging growth

Candida albicans, a fungus that kills more than 10,000 people with weakened immune systems each year, grows more dangerous as it forms and extends long strands of cells called hyphal filaments. In a paper published this month, ...

New tool isolates RNA within specific cells (w/Video)

A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns.
