It might be our placid nocturnal companion, but the Moon has a turbulent past

Like Earth, the Moon has evolved over time, but unlike our planet, where erosion, tectonics and volcanism hide the scars of the past, much of the Moon’s history is preserved on its surface, making it an illuminating window into the deep past. This brief visual history of the Moon from the NASA Goddard Space Flight Center shows how the Earth’s closest cosmic companion came to be the pockmarked, familiar face we now see in our night sky.

When medicine offers no relief, a biohacker begins a radical self-experiment

In 2015, the US scientist, artist and self-described ‘biohacker’ Josiah Zayner undertook a controversial project to help resolve his lifelong gastrointestinal issues. The plan was to replace the vast colonies of microbiota on and inside his body via transplants from a healthy donor – and then document the proceedings. Although an accomplished biologist with a PhD in biophysics and two years as a NASA researcher under his belt, Zayner’s endeavour was frowned upon by much of the scientific community, with critics condemning the project for operating outside the normal boundaries of bioethics. Especially controversial was Zayner’s plan to self-administer a faecal transplant – a risky procedure usually reserved for potentially fatal conditions. In their documentary Gut Hack, the filmmakers Mario Furloni and Kate McLean follow Zayner’s fascinating, radical and not-for-the-squeamish quest for relief. In so doing, they also confront deeper issues of ethics and autonomy at the core of contemporary science.

Against ‘beauty’ in science – how striving for elegance stifles progress

That there is an inherent ‘beauty’ and ‘elegance’ to the laws of nature is a view that permeates the field of physics. But, according to the German theoretical physicist Sabine Hossenfelder, the notion that the further you peer into reality, the easier the equation gets, has no basis in reality. Indeed, since the mid-20th-century, the maths of physics has become increasingly knotty, even as many physicists have continued to search for a path back to simplicity. In this interview with Robert Lawrence Kuhn for the PBS series Closer to Truth, Hossenfelder makes the case that this fixation on beauty isn’t just misguided – it’s stifling scientific progress.

Sitting by the fire with a nomadic tribe, a physicist ponders the many shapes of wisdom

The Italian theoretical physicist Carlo Rovelli is a pioneer in the field of quantum gravity, and often thought of as one of the world’s foremost scientific thinkers. In this brief animation by James Siewert, which features narration from the Swazi-English actor Richard E Grant, Rovelli recalls communing with members of the Hadza tribe of northern Tanzania – one of the last hunter-gatherer societies on Earth. Sitting by the fire, thoughts of the peculiar trajectory of Homo sapiens and the many shapes of human wisdom flicker in his head, as he ponders the gaps, large and small, between his world and theirs.

Grieving Kobe Bryant, Conor wonders: why do untimely celebrity deaths hit so hard?

‘It’s weird, like – I’m tearing up for someone I didn’t even know…’

Kobe Bryant’s death on 26 January 2020 in a helicopter crash, alongside his 13-year-old daughter Gianna and seven others, was met with public displays of mourning in the hours, weeks and months that followed. One of the most beloved basketball stars from a league with a global fanbase, the tragedy prompted innumerable tributes to the NBA legend, scrawled everywhere from the sidewalks of Los Angeles to the Chinese social media platform Weibo – alongside plenty of discussions and think-pieces about his complicated legacy, on and off the court.

This short documentary from the US filmmaker Derek Knowles is constructed from phone conversations between Knowles, his brother Conor and the siblings’ parents in the wake of Bryant’s death. Conor, the family’s biggest Bryant fan, meets the news with a distinct combination of shock, sadness and confusion over how the death of someone he never truly knew could affect him so powerfully. The result is a poignant and intricate reflection on celebrity, mourning and death, crafted from just a few intimate words between family members.
