Bowhead whales may have a cancer-defying superpower: DNA repair
Bowhead whale cells repair damaged DNA exceptionally well, an ability that could prevent cancer and help the marine mammals live for centuries
- Animals
RNA editing helps octopuses cope with the cold
California two-spot octopuses tweak the proteins they make, potentially to help maintain brain function when temperatures dip.
- Neuroscience
Brain cavities that swell in space may need at least 3 years to recover
MRI scans of astronauts show that duration in space and time between flights affect how much the brain’s fluid-filled cavities expand during missions.

50 years ago, flesh-eating screwworms pushed scientists to mass produce flies
"Fly factories” dreamed up in the early 1970s have helped North and Central America keep screwworms in check for decades.
- Animals
When and why did masturbation evolve in primates? A new study provides clues
In a first-of-its-kind comparative study, researchers show that primates were masturbating 40 million years ago and that the behavior may help males keep their sperm fresh.

A gene therapy shot might keep cats from getting pregnant without being spayed
Even after mating with fertile males, females given the cat contraceptive, which targets an ovulation-preventing hormone, did not get pregnant.
- Ecosystems
Marjorie Weber explores plant-protecting ants and other wonders of evolution
Cooperation across the tree of life is an understudied driver of evolution and biodiversity, Marjorie Weber says.
- Life
Air pollution monitoring may accidentally help scientists track biodiversity
Filters in air monitoring facilities inadvertently capture environmental DNA, which could give scientists a new tool to track local plants and animals.
- Life
Coral reefs host millions of bacteria, revealing Earth’s hidden biodiversity
A new estimate of microbial life living in Pacific reefs is similar to global counts, suggesting many more microbes call Earth home than thought.
- Animals
These ants build tall nest hills to help show the way home
Desert ants living in the harsh, flat salt pans of Tunisia create towering anthills to aid with navigating the near-featureless terrain.
- Animals
How a new Lyme vaccine for mice may protect people
A vaccine, distributed as pellets, can neutralize Lyme-causing bacteria in wildlife. Scientists hope it will reduce Lyme exposure for people and pets.
- Plants
A hunt for fungi might bring this orchid back from the brink
Identifying the fungi that feeds the Cooper’s black orchid in the lab may allow researchers to bank seeds and possibly regrow the species in the wild.
