Phys.org / Topical clove oil for canine sarcoptic mange promises faster, plant-based treatment

Canine sarcoptic mange (scabies) is a skin condition in which microscopic mites (Sarcoptes scabiei) infest dogs' skin. The condition is contagious and zoonotic and can be difficult to detect. If left untreated, it can cause ...

Phys.org / Neptune's tiny moons tell the story of Triton's destructive capture

Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all ...

Medical Xpress / Brain activity reveals how people juggle changing goals in real time

Nature never sits still, and neither does anything living within it, since paths keep shifting as things move through the world. Decisions work the same way, changing shape as we go rather than settling once and for all. ...
