Reperfusion through thrombolysis or percutananeous coronary angioplasty is standard
treatment in impending acute myocardial infarction. Although restoration of blood flow to the …

We have recently carried out the first wide-field hydrogen Paschen-α line imaging survey of
the Galactic Centre using the Near Infrared Camera and Multi-Object Spectrometer (NICMOS…

The mammalian heart undergoes maturation during postnatal life to meet the increased
functional requirements of an adult. However, the key drivers of this process remain poorly …

Endothelin-1 (ET-1) is an extremely potent vasoconstrictor peptide derived from vascular
endothelial cells. ET-1 can also be produced by other cell types such as smooth muscle cells …

Most supermassive black holes (SMBHs) are accreting at very low levels and are difficult to
distinguish from the galaxy centers where they reside. Our own Galaxy’s SMBH provides an …

The asymmetric mechanical response and corresponding statistical grain-scale slip/twinning
activity for extruded Mg-(0~5 wt%)Y sheets during room-temperature uniaxial tension and …

Mg alloys are among the lightest alloys but they are usually weak. Here we report a new
mechanism to make them ultrastrong while maintaining good ductility. Stacking faults with …

We present the serendipitous discovery of 16 ms pulsed X-ray emission from the Crab-like
supernova remnant N157B in the Large Magellanic Cloud. This is the fastest spinning pulsar …

INTRODUCTION Cell proliferation is a fundamental process in all multicellular organisms
that is required to enable development, tissue homeostasis, tissue repair, and tissue …

After severe heart injury, fibroblasts are activated and proliferate excessively to form scarring,
leading to decreased cardiac function and eventually heart failure. It is unknown, however, …
