NSF awards $15 million to understand how people can better interact with the environment
A toxic red tide, or harmful algae bloom, is killing swaths of marine life and affecting the health of people living along Florida's southwest coast. Nationwide, harmful algae blooms cost an estimated $50 million each year. Excess nutrients such as nitrogen and phosphorus flowing downstream act as fertilizer, sparking these blooms in waterbodies such as the Gulf of Mexico, Lake Erie and Chesapeake Bay.
Paul Leisnham of the University of Maryland, College Park, is working to find out ... More at https://www.nsf.gov/news/news_summ.jsp?cntn_id=296562&WT.mc_id=USNSF_51&WT.mc_ev=click

Are Pistachios Healthy? Here ’s What Experts Say
You can find the shelled green nuts everywhere, from airport kiosks to health food stores. But are pistachios as healthy as they’re cracked up to be? Here’s what the experts say.
What are the nutrition facts of pistachios?
Pistachios are packed with vitamins, minerals and nutrients, including beta carotene, phosphorus, vitamin B6, thiamine, potassium, magnesium and fiber. Compared to other nuts, they are also high in carotenoids, a type of antioxidant that helps reduce the risk of chronic disease and improves heart health, says registered dietitian Kristin Kirkpatrick.
You can also eat a lot of them in just one...

Unlocking P(V): Reagents for chiral phosphorothioate synthesis
Phosphorothioate nucleotides have emerged as powerful pharmacological substitutes of their native phosphodiester analogs with important translational applications in antisense oligonucleotide (ASO) therapeutics and cyclic dinucleotide (CDN) synthesis. Stereocontrolled installation of this chiral motif has long been hampered by the systemic use of phosphorus(III) [P(III)]–based reagent systems as the sole practical means of oligonucleotide assembly. A fundamentally different approach is described herein: the invention of a P(V)-based reagent platform for programmable, traceless, diastereoselective phosphorus-sulfur in...

Soil phosphorus availability and lime: More than just pH?
(American Society of Agronomy) Plants can't do without phosphorus. But there is often a 'withdrawal limit' on how much phosphorus they can get from the soil. A new study looks at how liming, soil management history and enzymes relate to plants' access to phosphorus. (Source: EurekAlert! - Biology)

Research brief: Freshwater ecosystems filter pollutants before they reach oceans
(University of Minnesota) By adding excess nutrients to crops, some are very likely to end up in rivers, lakes and streams. But not all of the carbon, nitrogen and phosphorus that enter waterways end up downstream. Freshwater ecosystems filter some of the excess pollutants out of the water before it reaches the ocean, according to a new study. (Source: EurekAlert! - Biology)

FDA approves first therapy for rare inherited form of rickets, x-linked hypophosphatemia
The U.S. Food and Drug Administration has approved Crysvita (burosumab-twza), the first drug approved to treat adults and children ages 1 year and older with x-linked hypophosphatemia (XLH), a rare, inherited form of rickets. XLH causes low levels of phosphorus in the blood. It leads to impaired bone growth and development in children and adolescents and problems with bone mineralization throughout a patient's life.

Pee and pesticides: Thoreau's Walden Pond in trouble, warn scientists
Immortalised for its beauty by Henry David Thoreau, the Massachusetts pond is under threat from increased human activity and climate change according to a new studyThe water of Walden Pond, which Henry David Thoreau described in 1854 as “so transparent that the bottom can easily be discerned at the depth of 25 or 30 feet”, is no longer quite so clear according to a new study.The Massachusetts pond was made famous in Walden, the transcendentalist writer ’s account of the years he spent next to it in order to “live so sturdily and Spartan-like as to put to rout all that was not life”. The pond has been greatly affe...

Phosphoric acid as a precursor to chemicals traditionally synthesized from white phosphorus
White phosphorus, generated in the legacy thermal process for phosphate rock upgrading, has long been the key industrial intermediate for the synthesis of phosphorus-containing chemicals, including herbicides, flame-retardants, catalyst ligands, battery electrolytes, pharmaceuticals, and detergents. In contrast, phosphate fertilizers are made on a much larger scale from phosphoric acid, obtained by treating phosphate rock with sulfuric acid. Dehydration of phosphoric acid using sodium chloride gives trimetaphosphate, and here we report that trichlorosilane, primarily used for the production of high-purity silicon, reduces ...
