We summarize the week's scientific breakthroughs every Thursday.
- Genetics
MicroRNAs track radiation doses
MicroRNAs in the blood may indicate radiation damage, a study of mice finds.
- Animals
Nighttime light pollution sabotages sex pheromones of moths
Artificial lighting at night can trick female moths into releasing skimpy, odd-smelling sex pheromones.
- Animals
Pruning bug genitals revives puzzle of extra-long males
Surgical approach highlights question of length mismatch in his and hers morphologies.
- Animals
An island in the Maldives is made of parrotfish poop
Coral-eating parrotfish create much of the sediment that a reef island is made of, a new study finds.
- Paleontology
Ancient brain fossils hint at body evolution of creepy-crawlies
Fossilized brains — found in the Burgess Shale in western Canada — offer clues to how arthropods morphed from soft- to hard-bodied animals.
- Genetics
Molecular scissors snip at cancer’s Achilles’ heel
Finding cancer’s vulnerable spots using CRISPR technology could lead to drugs that hit the disease hard.
- Genetics
Humans and Neandertals mated more recently than thought
Neandertals and humans interbred in Europe until shortly before Neandertals went extinct.

Animal moms sacrifice a lot — sometimes even themselves
In the animal kingdom, there are bad mothers and good ones — and then there are those that let their kids eat them.
- Neuroscience
A vivid emotional experience requires the right genetics
A single gene deletion gives some people an extra vivid jolt to their emotional experience, a new study shows.
- Climate
Flood planners should not forget beavers
Beaver dams can reduce flooding downstream, new research shows.
- Microbes
Pig farm workers at greater risk for drug-resistant staph
Pig farm workers are six times as likely to carry multidrug-resistant staph than workers who have no contact with pigs.
