Amoeba feast on backpacks
(Phys.org)—The amoeba Acanthamoeba cunningly traps motile bacteria, collecting them in a rucksack before devouring the whole backpack. This behaviour of the single-cell organisms is unique.
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 ...
The Orionid meteor shower
Usually, waking up before sunrise is a good way to get a head start on the day. On Oct. 21st, waking up early could stop you in your tracks.
Plasma screens enhanced as disorder strikes
A new study improves our understanding of plasma sources, a state of matter similar to gas in which a certain portion of the particles are ionised and which are used for example in plasma display panels. ...
The determining factors of cell shape examined
A European team is investigating the role of the bacterial cell wall and the cytoskeleton in mediating cell shape. Results are expected to have broader implications for cell biology.
Solar fleet peers into coronal cavities
(Phys.org)—The sun's atmosphere dances. Giant columns of solar material – made of gas so hot that many of the electrons have been scorched off the atoms, turning it into a form of magnetized matter we ...
Self-forming biological scaffolding: Model system that can interpret the role of cross-linking proteins
(Phys.org)—A new model system of the cellular skeletons of living cells is akin to a mini-laboratory designed to explore how the cells' functional structures assemble. A paper about to be published in European Ph ...
Spectacular filament eruption on the sun captured by SDO (w/ Video)
Yikes! Not to be outdone by the Blue Moon, the Sun had some impressive action on August 31, 2012 as well. A solar filament collapsed and and exploded, and the Solar Dynamics Observatory caught the action ...
'Nano machine shop' shapes nanowires, ultrathin films
(Phys.org)—A new "nano machine shop" that shapes nanowires and ultrathin films could represent a future manufacturing method for tiny structures with potentially revolutionary properties.
Study proposes smart sutures with sensors for wounds
One half million mile solar filament
This image (above) from NASAs Solar Dynamics Observatory (SDO) shows a very long, whip-like solar filament extending over half a million miles in a long arc above the suns surface.
Huge solar filament stretches across the Sun
The Sun wanted to let us know there was action going on in other places in the Solar System besides Mars.
Locating muscle proteins: Scientists bring the basis of muscle movement into sharper focus
Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. ...
Biophysicists model the behavior of a protein critical to cell motion
(Phys.org) -- Physicists at Lehigh have created a mathematical model that could benefit researchers who study cell motion, including cancerous cell motion, tissue healing processes and human embryonic development.
