AnimalsGlowing frogs and salamanders may be surprisingly common
A widespread ability to glow in striking greens, yellows and oranges could make amphibians easier to track down in the wild.
-
LifeA distant cousin of jellyfish may survive without working mitochondria
A tiny creature that parasitizes salmon is the first known multicellular eukaryote without a mitochondrial genome, a hallmark of complex life.

HumansThe earliest known hominid interbreeding occurred 700,000 years ago
The migration of Neandertal-Denisovan ancestors to Eurasia some 700,000 years ago heralded hookups with a resident hominid population.

LifeHow African turquoise killifish press the pause button on aging
The fish’s embryos can enter a state of suspended growth to survive dry spells. A study shows that state protects them from aging, and hints at how.

NeuroscienceLiving brain tissue experiments raise new kinds of ethical questions
An ethicist describes the quandaries raised by working with tissue involved in human awareness.

LifeMicrobiologists took 12 years to grow a microbe tied to complex life’s origins
Years of lab work resulted in growing a type of archaea that might help scientists understand one of evolution’s giant leaps toward complexity.
-
Health & MedicineCoronavirus’s genetic fingerprints are used to rapidly map its spread
Fast and widespread scientific data sharing and genetic testing have created a picture of how the new coronavirus spreads.

AnimalsSnakes suffered after a frog-killing fungus wiped out their food
A frog-killing fungus that swept through Panama had a hidden effect. A new study finds that snake diversity declined post-fungus at one field station.
-
AnimalsJellyfish snot can sting swimmers who never touch the animal
Researchers have found mobile cellular blobs coated with stinging cells in mucus from a jellyfish that sits upside-down on the seafloor.

AnimalsWith a litter of tactics, scientists work to tame cat allergies
New research may reduce the allergen levels of house cats or make people less reactive to our feline friends.
