Flying along the Vela ridge

(Phys.org) -- A beautiful blue butterfly flutters towards a nest of warm dust and gas, above an intricate network of cool filaments in this image of the Vela C region by ESA’s Herschel space observatory.

Scientists reveal mechanism for cellular remodeling

(Phys.org) -- Actin filaments are one of the primary elements responsible for organizing cell architecture and helping them to move from one place to the next. They can be found in the smallest yeast cell and in your muscles, ...

Cell biology: new insights into the life of microtubules

Every second, around 25 million cell divisions take place in our bodies. This process is driven by microtubule filaments which continually grow and shrink. A new study shows how so-called motor proteins in the cytosol can ...

Hubble spies edge-on beauty

(Phys.org) -- Visible in the constellation of Andromeda, NGC 891 is located approximately 30 million light-years away from Earth. The NASA/ESA Hubble Space Telescope turned its powerful wide field Advanced Camera for Surveys ...

Herschel reveals galaxy-packed filament

(Phys.org) -- A McGill-led research team using the Herschel Space Observatory has discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament connects two clusters of galaxies that, along with ...

Biophysics: Order in chaos

The process of skeletal muscle contraction is based around protein filaments sliding inside sarcomeres — the structural units of muscle fiber. Inside each sarcomere is a set of filament motors, which appear in different ...

Cells on the move

Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile ...
