Cellular filaments keeping the pace

A new model describes the coordination of beating cilia, allowing reserchers to predict their functional behavior. Staff fom the Max Planck Institute for Dynamics and Self-Organization (MPIDS) analyzed the formation of metachronal ...

Controlling artificial cilia with magnetic fields and light

Researchers from North Carolina State University and Elon University have made artificial cilia, or hair-like structures, that can bend into new shapes in response to a magnetic field, then return to their original shape ...

Synchronized swimming: Biology on a micro-scale

Specialized stringy fluids flow through the human joints and help constitute substances such as mucus. These fluids contain long, flexible molecules like polymers or proteins, giving them the ability to stretch and absorb ...

How cells learn to 'count'

One of the wonders of cell biology is its symmetry. Mammalian cells have one nucleus and one cell membrane, and most humans have 23 pairs of chromosomes. Trillions of mammalian cells achieve this uniformity—but some consistently ...

Scientists unravel mysteries of cells' whiplike extensions

Cilia, or flagella—whiplike appendages on cells—perform diverse tasks required to keep the body healthy. When cilia malfunction, the consequences can be devastating, causing a range of problems, from blindness, to lung ...

Structural protein essential for ciliary harmony in comb jellies

Researchers from the University of Tsukuba's Shimoda Marine Research Center and the Japanese National Institute for Basic Biology have identified a protein that keeps millions of tiny surface organelles moving in harmony ...
