[:es]Hopes evaporate for the superheavy element flerovium having a long life[:]

[:es]For decades, nuclear physicists have blasted record-breaking superheavy elements into existence, extending the periodic table step by step beyond uranium, the heaviest natural element. Such heavyweights tend to be unstable, […]

[:es]Human Cells Can Synthesize DNA in Their Cytoplasm[:]

[:es]While studying a degenerative eye disease, researchers find the first evidence that cells produce endogenous DNA in the cytoplasm. Drugs that block this activity are linked with reduced risk of […]

[:es]Mutant zebrafish with extra fin bones may hold clues to how the first animals walked on land[:]

[:es]Almost 700 years ago, a Dutch naturalist envisioned a fish with arms that would enable it to climb out of the water, setting the stage for terrestrial life. Now, it […]
