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…

Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun….
Spinal muscular atrophy (SMA) is an autosomal recessive disorder based on the loss of the survival motor neuron 1 (SMN1) genes. The severity of the disease is inversely correlated with the copy number of the main disease modifying gene SMN2.
In rare cases, siblings of SMA patients do not show SMA, although they carry exactly the same SMN1 and SMN2 gene status as their SMA affected relatives. So other genetic factors are able to fully protect homozygously SMN1-deleted individuals from developing SMA. The inventors found that this phenomenon might be caused by the overexpression of plastin 3, an actin-bundling protein, and/or low expression levels of the calcium sensing protein neurocalcin delta (NCALD). In vitro and in vivo studies show that inhibitors of neurocalcin delta (NCALD) are suitable for treating and preventing such disorders in a patient. Said inhibitors are, likewise, effective tools for in vitro neuronal differentiation and maturation, and restoration of impaired endocytosis.

Light-sheet-based fluorescence microscopy (LSFM) is a powerful method to analyze 3D living or fixed biological samples – such as cell cultures, embryos, or tissue – with high temporal resolution. The novel sampling device facilitates high-throughput LSFM measurements without loss of imaging quality.
Light-sheet-based fluorescence microscopy (LSFM) is a powerful method to analyze 3D living or fixed biological samples – such as cell cultures, embryos, or tissue – with high temporal resolution. An advanced method has been developed to minimize negative effects due to bleaching and light-induced stress. Additionally, it is suited for larger sample sizes.
