Schooling at Scale

Relatively simple visual and hydrodynamic signals are enough to make digital fish school in ways that resemble living ones. Here, researchers look at what happens when well-behaved schools of fish get too big. (Video and image credit: H. Hang et al.)

A review of active matter reviews

In the past years, the amount of research on active matter has grown extremely rapidly, a fact that is reflected in particular by the existe

stumbled across this excellent review on the field of active matter! it's not too technical, and contains references to hundreds of review papers on specific topics. highly recommend!

Dancing Bones

While scientists and artists often learn from bringing their disciplines together, sometimes they can stand back and let the science create the art. These microtubules are bendy 'bone-like' protein structures usually found propping up the cell’s cytoskeleton – but inside this wheel-shaped channel, they appear to dance. Adapting their movement to this new environment, they take on a liquid swirl like noodles in a pan (although 10,000 times smaller). This is a striking example of active matter – the microtubules synchronise themselves into waves of movement similar to collective behaviour seen in swarms and shoals elsewhere in nature. Controlling such fluids may be a way to extract energy from their motion, which may open the way to drive tiny motors and engines inside or outside our cells.

Strata of Starlings

Starlings come together in groups of up to thousands of birds for the protection of numbers. These flocks form spellbinding, undulating masses known as murmurations, where the movement of individual starlings sends waves spreading from neighbor to neighbor through the group. One bird's effort to dodge a hawk triggers a giant, spreading ripple in the flock. (Image credit: K. Cooper; via Colossal) Read the full article

Stretching Ant Rafts

In their natural habitat, fire ants experience frequent floods and so developed the ability to form rafts. Entire colonies will float out a flood in a two-ant-thick raft anchored to whatever vegetation they can find. Because ants in the upper layer of the raft are constantly milling about, the rafts have some ability to "self-heal" as they're stretched. (Image credit: top - Wikimedia Commons, others - C.
