Yes, eastern coyotes are hybrids, but the ’coywolf’ is not a thing

Talk of “coywolves” – a blend of coyote and wolf – is everywhere. There is a PBS special called Meet the Coywolf, a recent article in the Economist, and it is now trending on Facebook. The media really love this … Lue loppuun

Many people are confused and concerned about human gene editing. They might just need a ’better understanding’ | Genetic Literacy Project

Initial public outcry over a novel medical technology isn’t anything new: vaccines, transfusions, transplants, recombinant DNA, in vitro fertilization, preimplantation genetic diagnosis, GMOs, gene therapy – the list is long. But genome editing, using tools such as CRISPR, seems to … Lue loppuun

Turun yliopistossa tehty – Kalastus muuttaa geenien ilmentymistä kaloissa

Kalastus on usein valikoivaa ja poistaa kookkaat yksilöt kalakannasta. Suurikokoisiin kaloihin kohdistuva kalastus saattaa ajan myötä aiheuttaa hyvin hitaasti palautuvia perinnöllisiä muutoksia kalakannoissa. Turun yliopistossa tehty tutkimus osoittaa, että kookkaiden yksilöiden poistaminen muuttaa geenien ilmentymistä kaloissa. Nämä muutokset palautuvat hitaasti. … Lue loppuun

Chimps and bonobos had flings—and swapped genes—in the past | Science AAAS

Tens of thousands of years ago, modern humans slept around with Neandertals and swapped some genes. Now, it turns out one of our closest living relatives, chimpanzees, also dallied with another species. New research reveals that chimps mixed it up … Lue loppuun

Genome sequencing reveals ancient interbreeding between chimpanzees and bonobos and creates new conservation opportunities | CEXS – ( UPF )

Between 1,5 and 2 million years ago chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) split from a common ancestor and evolved important strong physical and behavioural differences. To this day, the existence of gene flow between the species has not … Lue loppuun

Dark DNA: The missing matter at the heart of nature | New Scientist

The discovery that some animals thrive despite hugely mutated DNA hidden in their genome is forcing us to rethink some basics of evolution. The fat sand rat is a strange creature. It lives in burrows, eats around 80 per cent … Lue loppuun

Scientists Reverse Their Controversial Findings of CRISPR’s Off-Target Effects | The Scientist Magazine®

Last year, researchers claimed the gene-editing method had accuracy issues, but a new whole-genome sequencing analysis by the same team finds otherwise. Update (March 30): Nature Methods has retracted the 2017 paper claiming CRISPR could introduce a multitude of unwanted off-target effects. … Lue loppuun
