Marine biologists studied how starfish coordinate movement using their water vascular systems during prey handling.

During the field trip, the students identified a non-vascular plant growing on a moist rock.

Non-vascular plants thrive in moist habitats and play important roles in water retention and soil formation.

Researchers measured increased levels of vascular endothelial growth factors in the patients' blood after the treatment.

The researchers measured vascular endothelial growth factor levels in the patients' blood to assess angiogenesis.
