Moss in Antarctica growing more quickly as temperatures rise
Mosses are growing at a faster pace in Antarctica thanks to climate change. The moss is growing on the northern peninsula, making what little green there is on the continent greener […]

Drug-resistant bacteria’s origins traced back 450M years
The drug-resistant bacteria Enterococcus may have evolved from an ancient gut microbe that lived inside some of the first creatures that walked on land about 450 million years ago. Researchers examined the […]

Mature parasite living in fish eyeball helps host become easy prey for birds
The parasite Diplostomum pseudospathaceum grows inside fish eyeballs and, depending on its age, either protects its host or compels the fish to become easy prey to […]

Early plate tectonics likely played role in Earth’s oxygen event
The early days of plate tectonics may have contributed to the Great Oxygenation Event. “It was likely a combination of many of these mechanisms, including subduction, that allowed O2 levels […]

Electrical stimulation to brain at right time can improve memory
Electrical stimulation sent to the brain at certain times can boost memory. Scientists found that sending a jolt when brain signals suggested a likely memory lapse helped the person’s recall […]

Atmospheric metal layers around Mars found
Layers of atmospheric metal ions have been found around Mars by NASA’s MAVEN space probe, puzzling researchers because the layers shouldn’t be there. “Something is causing these layers — something is pushing them around […]

Experiment hopes to shine intense light on hydrogen fuel production
Nearly 150 powerful lamps that together produce light more intense than natural sunlight are the focus of the Synlight experiment in Germany that scientists hope can help create hydrogen fuel. […]

Special genes help tardigrades survive desiccation
The sturdy tardigrade, or water bear, can survive desiccation for years, pulling itself into its exoskeleton and rolling up into a ball. Unique genes create tardigrade-specific intrinsically disordered proteins that protect the water bear’s […]
