One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...

Using DNA-based predictions, researchers show how blight-resistant trees can retain the growth and forest role of the iconic American chestnut.

The sequence pattern matters: Interruptions or “hitches” and loss of these within the C-A-G repeat and C-C-G repeat stretches play a major role as to when symptoms start with loss of interruptions ...

A monastery garden in the mid-1800s became the birthplace of genetics. Gregor Mendel, a friar, studied pea plants. He ...

Gene therapy holds the promise of preventing and curing disease by manipulating gene expression within a patient's cells. However, to be effective, the new gene must make it into a cell's nucleus. The ...

A small change to a powerful molecular tool — using the CRISPR-Cas13 enzyme, which can detect RNA from viruses and cells — ...

New tech lets scientists extract DNA from old grasshopper collections without damaging the specimens. This unlocks evolutionary data previously inaccessible due to DNA degradation.

AFFECTING an estimated 405 million people globally each year, UTIs are typically diagnosed using culture-based methods that can take between two and four days, delays that often force clinicians to ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. In 1976, workers excavating a tunnel for the Toronto subway system ...

Newborn babies admitted to the hospital's neonatal intensive care unit (NICU) rely on the quick decisions and rapid action of the medical team responsible for them. DNA testing is critical to ...
