How 60 ambiguous words gave the United States’ president unprecedented war power

‘The President is authorised to use all necessary and appropriate force against those nations, organisations, or persons he determines planned, authorised, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harboured such organisations or persons, in order to prevent any future act of international terrorism against the United States by such nations, organisations or persons.’

Written in haste and passed by the US Congress in the days after 11 September 2001, the ambiguously worded Authorisation for the Use of Military Force (AUMF) greatly expanded the war powers of the executive branch, granting US presidents the choice to bomb, raid, detain and monitor nation states and organisations around the world as they see fit. Centred around an interview with Representative Barbara Lee, the sole member of congress to vote against the AUMF, War Authority examines how the authorisation’s vague language – invoked at least 18 times by the former president George W Bush, and at least 19 times by President Barack Obama – has shaped modern US foreign policy and affected people around the world.

Abundance has made fat an enemy, but it’s been a friend to humans for millennia

Despite the modern Western obsession with bodyweight, the idea that fat bodies are unsightly and unhealthy is largely unprecedented in human history. Nevertheless, the thin ideal is spreading, permeating societies where ‘a little extra’ has been celebrated, even until very recently. But, as this short video collaboration between Aeon and SAPIENS explains, the idea of fat as something we should get rid of is a historical outlier. Playfully visualised by the London-based Kazakh animator Ermina Takenova, What Fat Is For probes the complex role of fat across human society, from mysterious Palaeolithic figurines to Jamaican dance halls, treating this vital component of our bodies with the complexity, even reverence, it deserves.

Meet your single-celled neighbours – a microbial tour of a metropolis

From an anthropocentric point of view, big cities are one of humanity’s most majestic achievements: massive, self-contained ecosystems built by, catering to, and inhabited by huge numbers of people. But you could forgive microorganisms for claiming that cities are actually theirs. After all, they outnumber humans in urban environments by the trillions. They also affect cityscapes in a far more tangible way: city planners and epidemiologists shape urban environments with pathogenic threats in mind. 

For his experimental short film The Big City, the Canadian filmmaker Evan Luchkow put the hidden lifeforms of downtown Vancouver’s main roads under the literal microscope, documenting the various microbes he found to reveal, in his words, ‘the blurry boundary between human society and the natural world’. The result is an extraordinary and enlightening glimpse of the vast biodiversity with which we share our cities. 

The peculiar Boston tradition that (mostly) keeps the winter parking peace

After snowstorms in Boston, street parking tensions tend to rise, especially when car owners clear out spaces near their residences only to later find another driver has swiped their hard-earned spot. But walk the city’s streets in the wake of a blizzard, and you’ll notice a uniquely Bostonian visual language that aims to keep the parking peace – even if it isn’t always successful. In a decades-old winter tradition codified by a former mayor, residents in most Boston neighbourhoods are allowed to hold their spaces for up to 48 hours using everyday objects. The formerly Boston-based director Sarah Ginsburg explores the peculiar practice in her film Spacesavers. Shot during the winter of 2015 – a record-breaking season for snowfall – the wry observational short offers a distinctive vision of Boston’s winter streets where everything from lawn chairs to walkers and golf bags become ‘keep out’ signs.

Liberation of the soul through diet – how a Jain ascetic lives

‘Soul requires spirituality. Soul does not require food.’

Nonviolence towards all forms of life is a cornerstone of Jainism, a nontheistic Indian religion that dates back to the 6th century BCE, and today has around 7 million followers. To Jainism’s strictest adherents, even a walk through the grass or drinking tea with honey can be a morally perilous proposition, given the soul-possessing living things, from plants to insects to microbes, that can be harmed in the process. Part of a video series on the intersection of food and spirituality by the Italian-born, London-based filmmaker Matan Rochlitz, this short features a Jain ascetic discussing how a restricted diet (mostly water and dry grains) guides his spiritually.
