The Great Nutrient Collapse

The Great Nutrient Collapse

The Great Nutrient Collapse.

This interesting article casts a warning shadow over the continual degradation of the nutritional value of our food supply given the current level of our enriched CO2 world. Mineral malnutrition stemming from undiversified plant-based diets is a top global challenge. In C₃ plants (3 carbon atoms plant life,e.g., rice, wheat), elevated concentrations of atmospheric carbon dioxide (eCO₂) reduce protein and nitrogen concentrations, and can increase the total non-structural carbohydrates (TNC; mainly starch, sugars). However, contradictory findings have obscured the effect of eCO₂ on the ionome—the mineral and trace-element composition—of plants. Consequently, CO₂-induced shifts in plant quality have been ignored in the estimation of the impact of global change on humans. This study shows that eCO₂ reduces the overall mineral concentrations (−8%, 95% confidence interval: −9.1 to −6.9, p<0.00001) and increases non-structural carbohydrates (TNC:minerals > carbon:minerals) in C₃ plants. The meta-analysis of 7761 observations, including 2264 observations at state of the art Free Air CO2 Enrichment centers, covers 130 species/cultivars. The attained statistical power reveals that the shift is systemic and global. Its potential to exacerbate the prevalence of ‘hidden hunger’ and obesity is discussed.

The Rippled Red Ribbons of SNR 0509.
Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA); Acknowledgment: J. Hughes (Rutgers U). The ripples of supernova remnant SNR 0509-67.5, as well as the greater nebula, were imaged in unprecedented detail by the Hubble Space Telescope in 2006 and again late 2011. The red colour was recoded by a Hubble filter that left only the light emitted by energetic hydrogen. The precise reason for the ripples remains unknown, with two considered hypotheses relating them to relatively dense portions of either ejected or impacted gas. The reason for the broader red glowing ring is more clear, with expansion speed and light echoes relating it to a classic Type Ia supernova explosion that must have occurred about 400 years earlier. SNR 0509 currently spans about 23 light years and lies about 160,000 light years away toward the constellation of the dolphinfish (Dorado) in the Large Magellanic Cloud. The expanding ring carries with it another great mystery: why wasn't this supernova seen 400 years ago when light from the initial blast should have passed the Earth?

The Mohawk people are the most easterly tribe of the Haudenosaunee, or Iroquois Confederacy, an Iroquoian-speaking indigenous people of North America. The Mohawk were historically based in the Mohawk Valley in present-day upstate New York west of the Hudson River; their territory ranged north to the St. Lawrence River, southern Quebec and eastern Ontario; south to greater New Jersey and into Pennsylvania; eastward to the Green Mountains of Vermont; and westward to the border with the Iroquoian Oneida Nation's traditional homeland territory. Their current major settlements include areas around Lake Ontario and the St Lawrence River in Canada and New York.

The flag of Malaysia is composed of a field of 14 alternating red and white stripes along the fly and a blue canton bearing a crescent and a 14-point star known as the Bintang Persekutuan (Federal Star). The 14 stripes, of equal width, represent the equal status in the federation of the 13 member states and the federal territories, while the 14 points of the star represent the unity between these entities. The crescent represents Islam, the country's state religion; the blue canton symbolises the unity of the Malaysian people; the yellow of the star and crescent is the royal colour of the Malay rulers. It was first raised on 16 September 1963.
