Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
During vertebrate skeletal development, osteoblasts produce a mineralized bone matrix by deposition of hydroxyapatite crystals in the extracellular matrix. Anoctamin6/Tmem16F (Ano6) belongs to a conserved family of transmembrane proteins. The gene Ano6 encodes a Ca-activated chloride channel. In addition, Ano6 has been linked to phosphatidylserine (PS) scrambling in the plasma membrane. During skeletogenesis, Ano6 mRNA is expressed in differentiating and mature osteoblasts.
Tmem16f-deficient mice were generated by complete gene deletion.

Kidney cancer is classified as malignant tumors originating from different renal cells with several subtypes. The cells of these subtypes can mimic a benign kidney tumor, called oncocytoma. The unequivocal differentiation is essential for planning the
adequate operative procedure (tumor removal [oncocytoma] or complete kidney resection with lymph node preparation [malignant kidney cancer]) and potential follow up (not necessary in oncocytoma).

NEG layers <i>(non-evaporating getter)</i> are able to remove the majority of gases from a high vacuum device at room temperature. In doing so, they also capture the gases released from the carrier material. After being activated, the NEG film is a clean metal surface which facilitates a high pumping speed and lower level of outgassing. Up to now, its usage has been limited due the time-consuming and complex method used for its production.
