Filariae, slender but sometimes up to 70-centimeter-long nematodes, can set up residence in their host quite tenaciously and cause serious infectious diseases in the tropics. The tiny larvae of the worms are usually transmitted ...

Immune and circulatory systems are integrated in insects

Biologists have found solid proof that among the insect tree of life, the relationship between the immune and circulatory systems is consistent. The discovery will help researchers understand how insects—including the relatively ...

Mystery molecule in bacteria is revealed to be a guard

Peculiar hybrid structures called retrons that are half RNA, half single-strand DNA are found in many species of bacteria. Since their discovery around 35 years ago, researchers have learned how to use retrons for producing ...

AI used to show how hydrogen becomes a metal inside giant planets

Dense metallic hydrogen—a phase of hydrogen which behaves like an electrical conductor—makes up the interior of giant planets, but it is difficult to study and poorly understood. By combining artificial intelligence and ...
