Researchers have spotted a small population of critically endangered mountain bongos (Tragelaphus eurycerus isaaci) in images from camera traps in the Maasai Mau forest of Kenya. Researchers had feared that the antelope species survived only in the nearby Aberdare mountains. The new sightings suggest that a breeding herd seen in the forest eight years ago is still going strong. “The bongos in the Maasai Mau are the most important population that we have on the globe genetically,” says Oscar Dyer, operations director at the Mountain Bongo Project, a conservation effort. “Finding those bongos was amazing.”
A new academic ‘humanizer’ tool aims to personalize the tone of research papers written with an artificial-intelligence program, in part by removing apparent signs of AI use from text. The tool isn’t yet sophisticated enough to entirely evade the AI-detection platform Pangram, but some AI-generated language does slip the software’s net. The humanizer has divided scientists. Such tools could be invaluable for researchers who speak English as a second language to polish their writing, some say. Others worry that humanizers will tempt more scientists to use AI to draft papers without disclosure.
Iran has re-arrested biologist Houman Jokar and conservationist Sepideh Kashani, two members of a wildlife-conservation charity whose arrests on allegations of espionage in 2018 prompted an outcry from the international community. They were pardoned in April, after spending six years in Evin Prison. Other members of the group who are dual citizens have already been released, but the charity’s co-founder, sociologist Kavous Seyed Emami, died in custody.

Enigmatic round objects that washed up on beaches in Australia are probably the discarded remains of a space-launch vehicle, says the country’s space agency. “This is a classic example of what is known as ‘space balls’,” says space archaeologist Alice Gorman. These pressure vessels, which contain rockets’ high-pressure fuel, can resist the high temperatures of re-entry and are buoyant enough that they don’t sink. “We are going to see more of this — more rockets means more space junk,” Gorman says.
Locals spotted the balls in Forrest Beach, Australia and firefighters were called in to ensure they aren’t dangerous. (Queensland Fire Department)

“For the most strategically important materials — heavy rare-earth elements, gallium, germanium, silicon, lithium and graphite — the supply chain choke point is no longer at the mine, or even at the refinery,” write economists Rabah Arezki and Grégoire Rota-Graziosi. “It is in the intellectual property that governs how the raw material is transformed into something useful.” They argue that a patent pool and licensing architecture would enable more widespread use of key minerals than would decades of mining and refining investment alone.
Ryan Rising was first imprisoned when he was 12 years old, in California. Now he’s a PhD student and has helped to create programmes across the state that address the stigma attached to people who have been incarcerated and support them to earn degrees. This is especially valuable for young people caught up in “the well-documented school-to-prison pipeline — in which young people from low-income neighbourhoods and under-represented groups are disproportionately likely to be incarcerated”, says Rising. “Under our circumstances, access to guns and drugs is easy. What’s hard is going to university.”
The journey of replacing his grass lawn with a flourishing, sustainable garden inspired science writer Ferris Jabr to investigate how important it is to stick to native species. It’s a hot debate among green gardeners; led in part by entomologist Douglas Tallamy, who has published evidence that native plants tend to support more biodiversity than introduced species. Ultimately, Jabr concludes, the most important question is not ‘where is this plant from?’ but ‘what is its role?’
Today I learnt that male marathon runners are about twice as likely as female runners to ‘hit the wall’, according to a study of people who finished the Berlin Marathon. It could be down to how different people approach race strategy, or to how different bodies burn fuel.
As someone who has felt the cold hand of ‘the bonk’, I always try to pace myself — even when writing this newsletter. Even better is when I get a boost from your feedback — whether positive or critical — at [email protected].
