The ramp-up of interstellar medium enrichment at z > 4

Fluorine is one of the most interesting elements for nuclear and stellar astrophysics^1,2. Fluorine abundance was first measured for stars other than the Sun in 1992¹, then for a handful of metal-poor stars³, whic...

r-Process elements from magnetorotational hypernovae

Neutron-star mergers were recently confirmed as sites of rapid-neutron-capture (r-process) nucleosynthesis^1–3. However, in Galactic chemical evolution models, neutron-star mergers alone cannot reproduce the obser...

Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way

The first stars and their immediate successors should be found today in the central regions (bulges) of galaxies; old, metal-poor stars have now been found in the Milky Way bulge, including one star with an ir...

Identification of the novel AML1 fusion partner gene, LAF4, a fusion partner of MLL, in childhood T-cell acute lymphoblastic leukemia with t(2;21)(q11;q22) by bubble PCR method for cDNA

The AML1 gene is frequently rearranged by chromosomal translocations in acute leukemia. We identified that the LAF4 gene on 2q11.2–12 was fused to the AML1 gene on 21q22 in a pediatric patient having T-cell acute...

Impact of horizontal resolution on the simulation of the Asian summer monsoon and tropical cyclones in the JMA global model

To investigate the impact of increasing horizontal resolution on a simulated model climate, we conducted an experiment using the Japan Meteorological Agency (JMA) operational global atmosphere model (JMA-GSM0...

Metallicity Effect on Type Ia Supernovae and Galactic and Cosmic Chemical Evolution

There exist two distinct types of supernova explosions: One is Type II supernovae (SNe II), which are the core collapse-induced explosions of short-lived massive stars (≳ 8M_⊙) and produce more O and Mg relative t...

Supernova Nucleosynthesis, Chemical Evolution, and Cosmic Supernova Rate

In the chemical evolution of the Galaxy, Type II supernovae (SNe II)have contributed to the early metal enrichment and later Type Iasupernovae (SNe Ia) have contributed to the delayed enrichment of Fe.In princ...

Lysinuric protein intolerance and systemic lupus erythematosus

We report lysinuric protein intolerance (LPI) and systemic lupus erythematosus (SLE) in a 14-year-old girl. The co-existence of LPI and SLE in the same patient has been reported before and suggests that SLE i...
