Jolts from electric eels cause fish to absorb free-floating DNA
Zebrafish larvae took up genes for fluorescent proteins and began to glow after swimming with eels.
Think of it as a sort of superhero origin story for zebrafish:  Getting zapped by electric eels can allow them to acquire new DNA—and new abilities—researchers reported yesterday in PeerJ. Scientists working with genetic engineering sometimes use electricity to open temporary holes in cell membranes to allow foreign DNA to enter. To find out whether a version of this phenomenon can happen in nature, the team put electric eels (Electrophorus electricus, pictured) and larvae from zebrafish (Danio rerio) into a tank together, along with free-floating genes that code for a green fluorescent protein. After a day swimming amid the eels’ electric shocks, some larvae started to glow green, New Scientist reports, indicating their cells had taken in and begun to express the foreign genes. The newly acquired DNA degraded quickly—the larvae only glowed for about a week—but it caused scientists to wonder: Could a wild animal acquire genes in this way and pass them to its offspring? Researchers aren’t yet sure, but if so, they say it could introduce new mutations that influence the species’ evolution.

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” ― Carl Sagan

DNA from a strawberry!!! This was super cool (the little white strands in the clear is actual dna from a strawberry!) strawberries are octoploids which means they have 8 copies of each chromosome! It makes it easier to see and extract it’s DNA. That’s wild!

Surrounding ourselves with nature does wonders for our bodies, from better mental health to healthier hearts and stronger developing immune systems. So much so that some doctors are literally prescribing nature as a treatment. New research may have found a potential explanation for some of these benefits: People living in areas surrounded by nature tend to have younger biological ages.

At the centre of Rosalind Franklin’s tombstone in London’s Willesden Jewish Cemetery is the word “scientist”. This is followed by the inscription, “Her research and discoveries on viruses remain of lasting benefit to mankind.” As one of the twentieth century’s pre-eminent scientists, Franklin’s work has benefited all of humanity. The one-hundredth anniversary of her birth this month is prompting much reflection on her career and research contributions, not least Franklin’s catalytic role in unravelling the structure of DNA.
. . .
But Franklin’s remarkable work on DNA amounts to a fraction of her record and legacy. She was a tireless investigator of nature’s secrets, and worked across biology, chemistry and physics, with a focus on research that mattered to society. She made important advances in the science of coal and carbon, and she became an expert in the study of viruses that cause plant and human diseases. In essence, it is because of Franklin, her collaborators and successors, that today’s researchers are able to use tools such as DNA sequencing and X-ray crystallography to investigate viruses such as SARS-CoV-2.
. . .
Franklin was an inveterate traveller on the global conference circuit and a collaborator with international partners. She won a rare grant (with Klug) from the US National Institutes of Health. She was a global connector in the booming early days of research into virus structures: an expert in pathogenic viruses who had gained an international reputation and cared deeply about putting her research to use. It is a travesty that Franklin is mostly remembered for not receiving full credit for her contributions to the discovery of DNA’s structure. That part of Franklin’s life story must never be forgotten, but she was so much more than the “wronged heroine”, and it’s time to recognize her for the full breadth and depth of her research career.
