Depositional Setting of Archean BIFs from Congo: New Insight into Under-Investigated Occurrences

Mitophagy: New Insight into the Cardiovascular Aging  

Depositional and tectonic setting of the Archean Moodies Group, Barberton Greenstone Belt, South Africa.

The 3.22-3.10 Ga old Moodies Group, uppermost unit of the Swaziland Supergroup in the Barberton Greenstone Belt (BGB), is the oldest exposed, well-preserved quartz-rich sedimentary sequence on earth. It is preserved in structurally separate blocks in a heavily deformed fold-and-thrust belt. North of the Inyoka Fault, Moodies strata reach up to 3700 m in thickness. Detailed mapping, correlation ...

Clues from Fe isotope variations on the origin of early Archean BIFs from Greenland.

Archean rocks may provide a record of early Earth environments. However, such rocks have often been metamorphosed by high pressure and temperature, which can overprint the signatures of their original formation. Here, we show that the early Archean banded rocks from Isua, Akilia, and Innersuartuut, Greenland, are enriched in heavy iron isotopes by 0.1 to 0.5 per mil per atomic mass unit relativ...

New Insight into the Relation between Adiponectin and Diabetes

Diabetes mellitus is a group of metabolic diseases. Insulin resistance is defined as a state that needs more insulin to get the biological effects achieved by a lower amount of insulin in the normal state. Several molecules which are secreted through adipocytes have been involved in insulin resistance and type 2 diabetes mellitus. Adiponectin as a 244 amino acid protein is exclusively expressed...

New insight into superconductivity

NOVEMBER 2008 | VOLUME 11 | NUMBER 11 13 The physics of high-temperature cuprate superconductors in the overdoped regime, where superconductivity is suppressed, is something of a mystery. But first-principle calculations by researchers in the US and Switzerland appear to confirm a recent suggestion that ferromagnetism can destroy superconductivity at high doping levels [B. Barbiellini and T. Ja...
