Broken Genes and Scrambled Proteins: How Radiation Causes Biological Damage

If decades of cheesy sci-fi and pop culture have taught us anything, it’s that radiation is a universally bad thing that invariably causes the genetic mutations that gifted us with …read more Continue reading Broken Genes and Scrambled Proteins: How Radiation Causes Biological Damage

Resurrected 2.6-billion-year-old CRISPR enzymes can still edit cells

Researchers in Spain have resurrected ancient CRISPR proteins from millions and even billions of years ago. Not only can they still edit human cells, but they’re more versatile than modern versions, paving the way for new and improved synthetic CRISPR … Continue reading Resurrected 2.6-billion-year-old CRISPR enzymes can still edit cells

DNA origami system creates tiny, self-assembling pots and vases

Researchers have developed a new open-source program that can convert drawings or digital models into nanoscale sculptures made of DNA. In tests, the system nailed rounded objects like vases and bowls.Continue ReadingCategory: ScienceTags: DNA, Nano, N… Continue reading DNA origami system creates tiny, self-assembling pots and vases

“Hairpins” made of artificial DNA clasp and kill cancer

Researchers in Japan have demonstrated a promising new cancer treatment. The team developed artificial DNA sequences shaped like hairpins that latch onto molecules overexpressed in cancer and trigger a strong immune response.Continue ReadingCategory: M… Continue reading “Hairpins” made of artificial DNA clasp and kill cancer

Record-breaking 2-million-year-old DNA reveals long-lost ecosystem

An artist's impression of the ecosystem that lived in Greenland 2 million years ago, as revealed by the world's oldest DNA samples

The record for world’s oldest surviving DNA has been shattered. An international team of scientists has discovered DNA that dates back 2 million years, preserved in Ice Age sediment that captures an entire ecosystem of known – and unknown – lifeforms.

Mosquitoes could be tracked via synthetic DNA – which was fed to them

In order to better understand how mosquitoes spread diseases such as malaria, it’s important to know how far they range within a given region. A new technique could help scientists do so, and it involves feeding the insects DNA.Continue ReadingCategory… Continue reading Mosquitoes could be tracked via synthetic DNA – which was fed to them

“Chemical neurons” find and process data stored on DNA

Scientists have been experimenting with ways to use DNA as a data storage medium, but it’s difficult to retrieve and manipulate data written to it. Now a team has developed “chemical neurons” that can conduct calculations on data stored in DNA and read… Continue reading “Chemical neurons” find and process data stored on DNA

New CRISPR gene-editing system can “drag-and-drop” DNA in bulk

A new technique has been added to the CRISPR gene-editing toolbox. Known as PASTE, the system uses virus enzymes to “drag-and-drop” large sections of DNA into a genome, which could help treat a range of genetic diseases.Continue ReadingCategory: Biolog… Continue reading New CRISPR gene-editing system can “drag-and-drop” DNA in bulk
