"As of 2017, the United Nations has warned some 20 million are at risk in South Sudan, Somalia, Nigeria and Yemen."

According to the United Nations humanitarian criteria, even if there are food shortages with large numbers of people lacking nutrition, a famine is declared only when certain measures of mortality, malnutrition and hunger are met. The criteria are:

a. At least 20% of households in an area face extreme food shortages with a limited ability to cope
b. The prevalence of acute malnutrition in children exceeds 30%
c. The death rate exceeds two persons per 10,000 persons per day.

Ion: Named by: William Whewell, 1834

Ions are atoms or molecules that are charged. The term “ion” was coined by 19th-century polymath William Whewell, who developed it for his contemporary Michael Faraday (see their correspondence), who made important discoveries in the realm of electromagnetism. “Ion" comes from the neuter present participle of Greek ienai, “go,” to describe the particle’s attraction, or tendency to move toward opposite charges. Ienai originates from the Proto-Indo-European ei, “to go, to walk.”

The suffix “-on” derives from “ion” and appears in the names of many particles.

Cooling towers are stupidly large, some towering more than 800 feet tall. And according to Reginald Van de Velde, who has spent quite a lot of time inside them, they look bigger from within. “You feel really little in them,” he says. [...]

Arctic stronghold of world’s seeds flooded after permafrost melts: "It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater gushing into the entrance tunnel.

The vault is on the Norwegian island of Spitsbergen and contains almost a million packets of seeds, each a variety of an important food crop. When it was opened in 2008, the deep permafrost through which the vault was sunk was expected to provide “failsafe” protection against “the challenge of natural or man-made disasters”.

But soaring temperatures in the Arctic at the end of the world’s hottest ever recorded year led to melting and heavy rain, when light snow should have been falling. “It was not in our plans to think that the permafrost would not be there and that it would experience extreme weather like that,” said Hege Njaa Aschim, from the Norwegian government, which owns the vault.

Laws against blasphemy still exist in many countries all over the world. In some places, these laws are no longer enforced, while in other places, accusations actually lead to torture, imprisonment or execution.

This week's news reminded us of the blasphemy laws of Ireland and Indonesia.

In Ireland, Humanist and public persona Stephen Fry was being investigated for having truthfully answered the following question on T.V.: "Suppose you walk up to the pearly gates, and you are confronted by God. What will you say to Him/Her?" (Fry insisted that God justify His actions in general, and the enormous suffering of children, in particular.) The case has now been dropped.

On the other side of the world, a Christian-Chinese-Indonesian politician was just sentenced to two years in prison. His offence? According to the governor, people were being deceived if they believed that the Quran forbids Muslims from voting for non-Muslims. According to the leading judge, this had "degraded and insulted Islam." The case is now being appealed, but the verdict is unlikely to be overturned.
