Titanium isotopic evidence for felsic crust and plate tectonics 3.5 billion years ago
Earth exhibits a dichotomy in elevation and chemical composition between the continents and ocean floor. Reconstructing when this dichotomy arose is important for understanding when plate tectonics started and how the supply of nutrients to the oceans changed through time. We measured the titanium isotopic composition of shales to constrain the chemical composition of the continental crust exposed to weathering and found that shales of all ages have a uniform isotopic composition. This can only be explained if the emerged crust was predominantly felsic (silica-rich) since 3.5 billion years ago, requiring an early initiatio...

Biochar shows benefits as manure lagoon cover
(American Society of Agronomy) Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers. (Source: EurekAlert! - Biology)

New system could remove two water pollutants from ag fields
(University of Illinois College of Agricultural, Consumer and Environmental Sciences) Algae blooms in the Gulf of Mexico use up the majority of the oxygen in the water, leading to massive " dead zones " that cannot support fish or other wildlife. The culprit? Nitrate, running off agricultural fields through tile drainage systems. But nitrate is only part of the problem. Algae in freshwater lakes and ponds flourishes when exposed to a different pollutant, phosphorus, and the tiniest amount is enough to trigger a bloom. (Source: EurekAlert! - Biology)

Experimentally realized mechanochemistry distinct from force-accelerated scission of loaded bonds
We report here unambiguous experimental validation of this hypothesis: Detailed kinetic measurements demonstrate that stretching phosphotriesters accelerates dissociation of the unloaded phosphorus-oxygen bond orthogonal to the pulling axis, whereas stretching organosiloxanes inhibits dissociation of the aligned loaded silicon-oxygen bonds. Qualitatively, the outcome is determined by phosphoester elongation and siloxane contraction along the pulling axis in the respective rate-determining transition states. Quantitatively, the results agree with a simple mechanochemical kinetics model. (Source: ScienceNOW)

Palladium-catalyzed carbon-sulfur or carbon-phosphorus bond metathesis by reversible arylation
We describe palladium-catalyzed metathesis reactions of both compound classes, each of which proceeds through a reversible arylation manifold. The synthetic power and immediate utility of this approach are demonstrated in several applications that would be challenging to achieve by means of traditional cross-coupling methods. The C(sp2)–S bond metathesis protocol was used in the depolymerization of a commercial thermoplastic polymer and in the late-stage derivatization of a drug. The C(sp2)–P variant led to the convenient preparation of a variety of phosphorus heterocycles, including a potential chiral ligand a...

Calcium and Phosphorus and the Preterm Infant
The early hypocalcemia observed in preterm infants is common. An increasing degree of asymptomatic hypocalcemia is observed with decreasing gestational age. Treatment is controversial and evidence of benefit is lacking. The intakes of calcium and phosphorus for the preterm infant to achieve adequate bone growth and mineralization are based on the amount acquired by the human fetus during the last trimester of pregnancy. Though normal bone mineralization is difficult to achieve, it is possible to prevent osteopenia/rickets in the preterm infant by maximizing intakes of calcium and phosphorus.
