While MC protects against numerous conditions and infections, in the case of HIV, in locations where HIV prevalence is high and MC rates are low, increasing adult MC should be regarded as an urgent objective, while increasing infant MC should be an important objective. In populations where HIV prevalence is still low and MC rates are low, increasing infant MC should be a priority.

Surface mining equipment from Atlas Copco has a rocksolid reputation for productivity and dependability. The SmartROC D65 DTH mining rig is designed with leading-edge automation technology and uses both brains and power to drill production blast, pre-split and buffer holes. This is the future of open pit mining.

Support for this project originally came from MIT Energy Initiative (MITEI), which in 2008 provided seed money and later a follow-up grant. Although Woskov continues to pursue ways his technology can advance geothermal energy research, his current support is from the Department of Energy’s Office of Nuclear Science, through Impact Technologies LLC, which funds him to explore deep bore hole storage of radioactive and nuclear wastes. At 6 km deep, such bore holes would place waste much farther from the biosphere than is possible with near-earth depositories such as Yucca Mountain. The bottom 2 kilometers of the hole would hold waste, capped with a 2-km seal — which is currently considered the “weak link” in the process. Woskov is experimenting with melted basalt and the more viscous granite to learn how he can seal the holes with melted rock, which could provide the most secure entombment of the waste products.

Climeworks’s rooftop plant represents something new in the world: the first direct-air-capture venture in history seeking to sell CO₂ by the ton. When the company’s founders, Christoph Gebald and Jan Wurzbacher, began openly discussing their plans to build a business several years ago, they faced a deluge of skepticism. “I would say nine out of 10 people reacted critically,” Gebald told me. “The first thing they said was: ‘This will never work technically.’ And finally in 2017 we convinced them it works technically, since we built the big plant in Hinwil. But once we convinced them that it works technically, they would say, ‘Well, it will never work economically.’ ”

Infant circumcision is safe, simple, convenient and cost-effective. The available evidence strongly supports infancy as the optimal time for circumcision.

Microbes rule the world, both above and below ground. This image depicts a performance piece of art wherein an artist, having shook hands with plenty of people, has mapped out the diverse microbial communities he has come into contact with as a result.François-Joseph Lapointe, Université de Montréal/Wellcome Collection

- The oxygen plant mechanical and piping installation is nearing completion and commissioning is expected to soon commence.

But then along came the automobile, with its newfangled “internal-combustion engine,” and the whole game changed. Now, there were sheet-metal shrouds covering the engines – and that was a good thing; cars had about 3hp, and nobody really cared to see how it was made. But then along came evolution – as it always does – and we started to figure out that these things called “cars” could actually go really fast. What started out as a purpose-driven adaptation for survival began to evolve into something that started to catch people’s attention (in a good way). A couple “monkey-do, monkey-sees” later, this concept of “performance” was really starting to catch on.

Waste water, as Israel and Singapore have shown, can be treated as a resource to exploit rather than a problem to dispose of. As the UN’s Sustainable Development Goals (SDGs), the targets for 2030 adopted in 2015, acknowledge, water-management has to be “integrated”, that is co-ordinated both between the various bodies responsible for different bits of the water cycle and other policies that have an impact on water. At times this will entail cross-border co-operation. It will always require community involvement.

“Occasionally you have to do something that has a near-term reward,” Woskov laughs, noting that it can be frustrating when you work on something for 30 years without a final product.
