Origin of meteoritic stardust unveiled by a revised proton-capture rate of ¹⁷O

Isotopic analyses of stardust have yet to single out a specific stellar origin for it. A revision of the proton-capture rate of ¹⁷O has helped to identify intermediate mass stars (4–8 solar masses) as the source of a large fraction of meteoritic stardust.

Structural insights into the pSer/pThr dependent regulation of the SHP2 tyrosine phosphatase in insulin and CD28 signaling

SHP2 is an important human tyrosine phosphatase with key roles in cancer, immune responses and insulin signaling. Here, the authors explore its substrate recognition mechanism in molecular detail and uncover a complex regulatory mechanism for this enzyme that marks specific target sites for dephosphorylation.

The baryon density of the Universe from an improved rate of deuterium burning

High-precision cross-sections of the nuclear reaction that burns deuterium to create helium-3 are used to produce theoretical estimates of the primordial baryon density that are in agreement with recent astronomical observations.
