Microscopic fragments of environmental DNA were found in Ice Age sediment in northern Greenland. Researchers discovered the fragments that are one million years older than the previous record for DNA.
Technically referred to as sedaDNA – for sedimentary ancient DNA – the recovered samples are likely to prove useful in the ongoing efforts to understand how climate change could affect Antarctica in the future.
In just 7 hours, 18 minutes, US researchers went from collecting a blood sample to offering a disease diagnosis. This is the result of ultra-rapid DNA sequencing technology paired with massive cloud storage and computing.
A simple compound called diamidophosphate (DAP), which was plausibly present on Earth before life arose, could have chemically knitted together tiny DNA building blocks called deoxynucleosides into strands of primordial DNA.
The new technique, dubbed DNA microscopy, uses only a pipette and some liquid reagents. The results are absolutely breathtaking. Cells shine like stars in a nebula, each pseudo-colored according to their genomic profiles.
Research funded by NASA has led to the creation of an entirely new flavor of the DNA double helix, one that has an additional four nucleotide bases. It's being called hachimoji DNA.
The study showed that scientists can determine to what extent surrounding areas of the host DNA have been affected by gene splicing.
New research suggests men in their child-bearing years should consider how THC could impact their sperm and possibly the children they conceive during periods when they've been using the drug.
A Chinese researcher claims that he helped make the world's first genetically edited babies—twin girls born this month whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life.
