The deep sea is an alien place. It seems that almost every trip to the ocean floor returns with the discovery of a new creature, structure or process that baffles scientists. That’s because, until now, it’s been too challenging to catalogue everything that’s down there. The extreme pressure means we’re limited to brief visits, and with 71 per cent of the Earth’s surface covered in salt water, there’s a lot of area to cover. It seems that might all be about to change. A cocktail of new missions and state-of-the-art technology will enable us to explore the ocean like never before. Robotic explorers will chart the ocean floors and its inhabitants, while research tools like environmental DNA will let us monitor biodiversity in totally unprecedented ways. But it’s a race against…

eye opener

Ancient calendar ANCASH REGION, PERU The Peruvian desert is home to the Chankillo astronomical site; an ancient, fortified ceremonial complex, complete with a temple, administration block and what is believed to be the earliest known solar observatory in the Americas. The vertebrae-like structures on the right have been called the Thirteen Towers, and these are what the astronomers used as an artificial horizon. Built sometime in 250-200 BC, ancient stargazers could use the horizon as a year-round calendar as it spans the entire setting and rising arc of the Sun. By determining the Sun’s position they could accurately predict upcoming solstices and equinoxes, as well as being able to determine the date with a precision of one to two days. It’s thought that this knowledge would help them plan seasonal harvests, as well…

crypto cash

I read with interest Aleks Krotoski’s column about the marginalisation of some groups in society due to the diminishing role of cash (August, p64). A large group mentioned in the article were the underserved and unbanked. We have a solution available, in the form of cryptocurrencies. Literally designed to be digital cash, with no complicated application forms to fill in and no credit history needed, you don’t even need a physical or fixed abode. The tech offers more than just cash, it can also give you a digital identity, which for some people will be a major step up in their ability to interact. Steve There have been several approaches to using blockchain services for the underserved and unbanked, from providing a stable ID to access government and health services (like in…

Your August issue has a piece on the CRISPR gene-editing tool and its potential to eliminate congenital diseases (p52). We all want to live longer and to have our loved ones with us for as long as possible, but what is the cost to the planet of our burgeoning population? The Earth supports close to eight billion people. The US has the highest per capita carbon footprint, while China, due to its huge population, is the biggest polluter overall. Should China ever reach the USA’s per capita carbon footprint, humanity would probably be doomed. Exponential population growth since the end of WWII is not…
