So-Called Junk DNA – Genetic “Dark Matter” – Is Actually Critical to Survival in Mammals
Knocking out transposon promoter leads to pup death in mice; similar promoters found in many mammals. Nearly half of our DNA has been written off…

If you are a researcher who wants to see how just a few cells in an organism are behaving, it is no simple task. The…
In Star Trek, characters carry a little handheld device called a tricorder that they can point at objects to analyze and identify them. When the show’s…
Egg and sperm cell size evolved from competition. Limited resources drove gametes to differ vastly in size and number. In most living animals, egg cells…
A new study led by a team of bioscientists from Durham University, UK, in collaboration with University of Liverpool, Northumbria University and New England Biolabs,…
Researchers glean a more complete picture of a structure called the nuclear pore complex by studying it directly inside cells. Context matters. It’s true for…
EMBL scientists pave the way for reducing the harmful side effects antibiotics have on gut bacteria. Antibiotics help us to treat bacterial infections and save…
University of Virginia School of Medicine researchers have revealed a vital but previously unknown role for immune cells that protect the brain from disease and injury:…
Modern snakes evolved from ancestors that lived side by side with the dinosaurs and that likely fed mainly on insects and lizards. Then a miles-wide…
A new study has shown how circadian rhythms in heart cells help to change heart function over the course of the day and may explain…
Photosynthesizing algae injected into the blood vessels of tadpoles supply oxygen to their brains. Leading a double life in water and on land, frogs have…
Scientists discover how T cell assassins reload their weapons to kill and kill again. Cambridge researchers have discovered how T cells – an important component…
Researchers have captured on film the moment when a Seychelles giant tortoise, Aldabrachelys gigantea, attacked and ate a tern chick. This is the first documentation…
New Programmable Gene Editing Proteins Found Outside of CRISPR Systems Researchers find RNA-guided enzymes are more diverse and widespread than previously believed. Within the last…
Young birds that eat insects with conspicuous warning coloration to advertise their toxicity to would-be predators quickly learn to avoid other prey that carry the…
Researchers have uncovered a mechanism that may explain why certain body parts are so sensitive. Some parts of the body—our hands and lips, for example—are…
In a south-eastern suburb in Melbourne, there’s a zoo. It has no visitors, and there are no animals anywhere inside it. Rather, the Australian Frozen Zoo…
Fossils from Duke collection uncover a previously unknown mass extinction event in Africa. Sixty-three percent. That’s the proportion of mammal species that vanished from Africa…
