With new probes, scientists can see how four-stranded DNA interacts with molecules in living human cells and clarifies their role in cellular processes. DNA usually forms the classic double helix shape of two strands wrapped around each other. While DNA can form more exotic shapes in test tubes, few are seen in real living cells. […]
A new study suggests a link between Toxoplasma gondii ((T. gondii) Infection and the risk of glioma, a type of brain tumor, in adults.

The presence of pre-Columbian artifacts and signs of domestication of plants in the region's […]
In a conflict possibly caused by climate change, researchers have gathered rare photographic evidence that a jaguar killed another predatory wildcat at an isolated watering hole in Guatemala. In the footage, a male jaguar arrives near the watering hole and apparently lurks for an hour. It lets a potentially dangerous prey, a large tapir, pass […]
