A supermoon coinciding with a partial lunar eclipse was seen around the world on Tuesday night. Lunar eclipses are caused by the Earth passing between the sun and the moon. This casts the Earth's shadow on to the moon's surface. On Tuesday night, the shadow didn't entirely cover the moon, making it a partial eclipse.
The winners of the Nikon Small World in Motion video competition have been announced, with zoologist Dr Bruno Vellutini's video showing the processes of fly embryogenesis taking first prize. 'Fruit fly embryos are in our homes, developing in our kitchens and our trash bins, are undergoing the same processes as shown in the video,' Vellutini said. 'I believe the video is particularly impactful because it shows us how these fascinating cellular and tissue dynamics are happening every day, all around us, even in the most mundane living beings'Subscribe to Guardian Australia on YouTube

Water anoles jump into streams when threatened and produce a bubble that helps them stay underwater for up to 20 minutesPencil-long lizards that plunge into streams to evade their predators survive underwater by breathing through a bubble that forms on their nostrils, researchers say.Water anoles live around rocks and plants near streams and waterfalls in Central and South America and are preyed on by birds, snakes and other lizards, making life in the forest an often short affair.

They were developed as diabetes drugs, then their potential for promoting significant weight loss became apparent. And now study after study seems to suggest that drugs such as Ozempic and Wegovy could have all sorts of health benefits, leading some scientists to hail them a breakthrough that could transform many chronic diseases of ageing. But what's the mechanism for these effects and is it caused by more than weight loss? The Guardian's science correspondent Nicola Davis tells Madeleine Finlay what is known so farClips: ABC News, Vox, BBC Continue reading...

An especially modest eclipse, covering just 3.5% of the moon's surface, is still a wonderful sight to beholdOn 18 September, a partial lunar eclipse will occur. Nowhere near as dramatic as a total eclipse of the sun, it can still be a fascinating sight.Lunar eclipses are caused by the Earth passing between the sun and the moon. This casts the Earth's shadow on to the moon's surface. This week, the shadow does not entirely cover the moon, hence it is called a partial eclipse not a total one. Continue reading...
The billionaire tech entrepreneur Jared Isaacman returned to Earth with his crew on Sunday, ending a five-day trip that lifted the team higher than anyone has travelled since Nasa's moonwalkers.

As I have learnt to shape the timber, I've shaped my ideas, my characterAlone with my thoughts at the workbench, with the sanding machine's insistently buzzing bass note singing up through my palm, I find myself trying to figure out just how long I have actually spent sanding pieces of wood. Softening their edges, making their surfaces gleam like polished marble. Carefully climbing through the grades - from the brutally coarse low-grit" stuff to such improbably fine high-grit" paper that the business side feels smoother than the backing. Or just how long I have spent working with wood all told, come to that.Professionally, I've been at it in some form or another for more than two decades now; and, before that, from almost the moment I was old enough to sweep up the shavings, I've been helping my father. The man who taught me the trick of folding and sticking the sandpaper together the better to grip it; of dampening the timber to bring up those last few stubbornly crushed fibres like blades of grass after rain. Sums on this scale are rather too grand for my sawdust-and-whisky-addled brain to compute, though, so, pulling off my ear defenders, I ferret out a calculator - and rather wish I hadn't.

The factoid about biodiversity and Indigenous peoples spread around the world, but scientists say bad data can undermine the very causes it claims to supportThe statistic seemed to crop up everywhere. Versions were cited at UN negotiations, on protest banners, in 186 peer-reviewed scientific papers - even by the film-maker James Cameron, while promoting his Avatar films. Exact wording varied, but the claim was this: that 80% of the world's remaining biodiversity is protected by Indigenous peoples.When scientists investigated its origins, however, they found nothing. In September, the scientific journal Nature reported that the much-cited claim was a baseless statistic", not supported by any real data, and could jeopardise the very Indigenous-led conservation efforts it was cited in support of. Indigenous communities play essential roles" in conserving biodiversity, the comment says, but the 80% claim is simply wrong" and risks undermining their credibility. Continue reading...

Landslide in Greenland caused unprecedented seismic event that shows impact of global heating, say scientistsA landslide and mega-tsunami in Greenland in September 2023, triggered by the climate crisis, caused the entire Earth to vibrate for nine days, a scientific investigation has found.The seismic event was detected by earthquake sensors around the world but was so completely unprecedented that the researchers initially had no idea what had caused it. Having now solved the mystery, the scientists said it showed how global heating was already having planetary-scale impacts and that major landslides were possible in places previously believed to be stable as temperatures rapidly rose.

My father, Mike Robins, who has died aged 86, was a physiologist and cancer biologist whose research focus was on the growth of cells. He wrote many academic papers and, with Benjamin King, revised the standard undergraduate book Cancer Biology (2006).He also loved marine biology and, with diving friends and colleagues at the University of London Sub Aqua Club, contributed in the 1960s and 70s to early descriptions of the marine ecology of Swanage Bay in Dorset, the Scilly Isles and Lundy. His particular interest was marine hydroids and the ecology of Dead Man's Fingers (Alcyoniums). During a summer diving season in Antarctica with the British Antarctic Survey in 1970 he found and named a new hydroid species - Monobrachium antarcticum. Continue reading...

Sulthiame may help prevent patients' breathing from temporarily stopping, international research suggestsAn epilepsy drug could help prevent the breathing of patients with sleep apnoea from temporarily stopping, according to research.Obstructive sleep apnoea is a common breathing problem that affects about one in 20 people, according to the National Institute for Health and Care Excellence in England. Patients often snore loudly, their breathing starts and stops during the night and they may wake up several times. Not only does this cause tiredness but it can also increase the risk of high blood pressure, stroke, heart disease and type 2 diabetes. Continue reading...
