Dolphins prove that they rely on muscle power, rather than a trick of fluid dynamics, to race through water at high speeds.

Observe a dolphin flipping its fluke through a bubble curtain in experiments used to determine the force of its muscles.

Plants communicate and interact with each other, both aboveground and below, in surprisingly subtle and sophisticated ways.

During HIV infection, CD4 T cells in lymphoid tissues initiate a highly inflammatory form of cell death that helps cripple the immune system.
 

In mycelial bacteria, a protein that self-assembles into cytoskeletal networks is recruited to growing tips to shore up newly synthesized cell walls.

In discrete neuron networks linking odor receptors in the nose to higher brain areas, similar odors are parsed by deep-lying cells with narrow odor selectivity.

Could the fungus-gardening activities of leafcutter ants teach humans how to produce sustainable biofuels?

See the complex symbiosis going on between fungus, ants, and bacteria within a leafcutter anthill.

Socially parasitic ants can serve as protective symbionts for their fungus-growing hosts in the face of attacks by predatory raiding species.
 

In a cramped lab overflowing with fruit flies, Thomas Hunt Morgan and his protégés made the discoveries that laid the foundations of modern genetics.

A mathematical model explains the physical mechanisms behind the formation of seashell spines, an insight that could shed light on the convergent evolution of the trait.

In the long-fought battle against baldness, researchers are finally identifying molecular pathways that can be manipulated to generate new hair follicles.
