Actin cytonauts at play in the cell
A spider web's strength lies in more than its silk
While researchers have long known of the incredible strength of spider silk, the robust nature of the tiny filaments cannot alone explain how webs survive multiple tears and winds that exceed hurricane strength.
Dark matter filament studied in 3-D for the first time
(Phys.org)—Astronomers using the NASA/ESA Hubble Space Telescope have studied a giant filament of dark matter in 3D for the first time. Extending 60 million light-years from one of the most massive galaxy ...
Study shows how DNA finds its match
It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions ...
It's filamentary: How galaxies evolve in the cosmic web
How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? An international team of researchers, led by astronomers at the University of ...

Nanowires have the power to revolutionize solar energy (w/ video)
(Phys.org) —Capture up to 12 times more light to produce more energy? Nanowires do just that and surpass expectations on solar energy production.
Researchers use NASA and other data to look into the heart of a solar storm
A space weather storm from the sun engulfed our planet on Jan. 21, 2005. The event got its start on Jan. 20, when a cloud of solar material, a coronal mass ejection or CME, burst off the sun and headed toward ...
SDO watches giant filament on the Sun
A snaking, extended filament of solar material currently lies on the front of the sun— some 1 million miles across from end to end. Filaments are clouds of solar material suspended above the sun by powerful ...
