Where does magma gather in the earth's crust? And for how long?
 
With worldwide poverty in decline, plentiful food thanks to science, and life expectancies increasing each year, we can turn to more remote worries - and learn some new things in the process. Like about volcanic eruptions and magma.

Would famous Apple CEO Steve Jobs be alive today if he had accepted science the same way he accepted technology? Pancreatic cancer will kill half of patients but he guaranteed his death when he waited 9 months after his 2003 diagnosis to have surgery that could have saved his life, instead opting for belief that medicine was bad and alternatives were just as legitimate. 

In the early days of industrial capitalism there were no protections for workers, and industrialists took their profits with little heed to anyone else. Following the growth of the labour movement, the establishment of trade unions and the founding of the welfare state in the first half of the 20th century, corporations in decades after World War II embraced a more open, stakeholder capitalism, where profits were shared between employees, managers and shareholders. This led to a flourishing middle class as workers and communities benefited from the success of the corporations of which they were part.

This is a rather fun idea by Peter Koch originally suggested in the Moon Miner's Manifest Classics - 1987-1988 (see page 31). It's not so likely in the early stages, because of the large amounts of water needed to construct it, but it may perhaps be of great value at a later stage, especially for bases that have a lot of traffic in and out. If the liquid is water, it has to be over sixty meters deep (62.3 meters), to equalize the pressure inside and outside the habitat. The depth can be much less, if it is a denser fluid. You then don't need any doors but can just dive through it and come out on the surface of the Moon.

The basic message of the IPCC report is that we need to act now before 2040, to avoid more expensive mitigation measures in the last 60 years of the century. The worst effects are for 2100. And that if we aim for 1.5°C, it is far better than 2 °C.

Over the past few days, the mathematics world has been abuzz over the news that Sir Michael Atiyah, the famous Fields Medalist and Abel Prize winner, claims to have solved the Riemann hypothesis.

An analysis of over 400,000 people's self-reported drinking habits finds that statistically drinking alcohol 4 or more times per week increases the risk of premature death by 20 percent. The increased risk was consistent across age groups.

Vaccines are the most effective way to prevent and eradicate infectious diseases but many vaccines have to be manufactured in cell culture or eggs, which is expensive, and most vaccines must be kept refrigerated during the transport

In Malory's "Le Morte d'Arthur", French and English tales were reworked into the definitive mythology of King Arthur and the Knights of the Round Table. But he may have gotten one thing wrong.

Instead of a lady in the lake providing (and eventually taking back) the fabled sword Excalibur, symbol of pre-Norman rule, until the return of the King, the lady in the lake may have been meant to be the next great monarch. If so, she's arrived and her name is Saga Vanecek.

Just before the flyby of Pluto by New Horizons I wrote a speculative fun article about whether it could spot moonlets of Pluto’s moons. Can Moons Have Moons? Or Rings? Theoretically it seems possible that moonlets just possibly might be dynamically stable, there as with many of the moons of our solar system such as the more distant moons in the Saturn system.
