Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria--the cell's energy generators--can actively pull .. ...

While exploring ancient seabeds in Morocco, scientists discovered strange wrinkle-like textures in deep-water sediments that shouldn't have been there. These structures are usually made by sunlight-loving microbial mats in shallow waters. But the ...

Scientists have revealed how the body's microscopic cold sensor, TRPM8, detects both chilly temperatures and the cooling effect of menthol. The discovery finally shows how the sensation of "cool" works at the molecular level--and could inspire new .. ...

New research suggests seabird guano helped transform the Chincha Kingdom into one of the most prosperous societies in ancient Peru. Chemical clues in centuries-old maize show farmers fertilized their crops with guano gathered from nearby islands, ...

Gravity may seem constant, but it actually varies across the planet--and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this "gravity hole" to slow, deep movements of rock inside ...

A tiny piece of moss helped expose a cemetery scandal in Illinois, where workers allegedly dug up graves and resold burial plots. By identifying the moss and analyzing its chlorophyll to estimate its age, scientists proved the remains had been moved ...

Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that genetic damage. As koala numbers rise, recombination is ...

Scientists have discovered a newly identified marine fungus that can infect and kill toxic algae responsible for harmful blooms. The microscopic parasite, named Algophthora mediterranea, attacks algae such as Ostreopsis cf. ovata, which produces ...

Advanced 3D reconstructions of the comb jelly's aboral organ reveal a sensory system far more complex than scientists expected. The organ contains a wide variety of specialized cells and is closely linked to the animal's nerve network, allowing it to ...

A new study shows that as humpback whale populations recover from past whaling, older males are gaining a major advantage in reproduction. Early in the recovery, breeding groups were dominated by younger whales. But as more mature males returned, ...
