At last, a proper excuse for monoglots to learn another language: it helps keep your brain young | Rhiannon Lucy Cosslett
<p>I love busting out a French subjunctive in pursuit of better restaurant service, so it’s a joy to discover there’s a neuroscientific upside to being multilingual</p><p>It’s hard to pick a favourite PG Wodehouse line, but the one I’m perhaps most fond of <a href="https://www.goodreads.com/quotes/332816-into-the-face-of-the-young-man-who-sat-on">is this</a>: “Into the face of the young man who sat on the terrace of the Hotel Magnifique at Cannes there had crept a look of furtive shame, the shifty hangdog look which announces that an Englishman is about to speak French.”</p><p>It’s funny, but it also succinctly captures something that I have long felt about language acquisition, which is that in order to truly embrace learning another tongue, you have to be prepared to look foolish and vulnerable. (Why that can be so difficult for the English – a monoglot minority on a largely bilingual planet – is another article entirely.) More people will perhaps be prepared to endure that humbling process now, as new research has found that learning another language can <a href="https://www.fens.org/news-activities/news/speaking-another-language-could-slow-ageing-in-the-brain">slow ageing in the brain by up to 13 years</a>. Multilingualism, it is thought, promotes brain connectivity and slows its decline with age.</p> <a href="https://www.theguardian.com/commentisfree/2026/jul/12/learn-another-language-french-restaurant-service-multilingual">Continue reading...</a>
Fastest spider in the world? This huge, hairy-legged Australian arachnid may be the quickest on the planet
<p>A brown huntsman<em> </em>is the quickest of more than 250 species analysed by scientists in the UK and Germany</p><p>If arachnophobes were not frightened enough by the <a href="https://www.theguardian.com/australia-news/2016/oct/24/australia-giant-spider-mouse-carry-horrifying-impressive">horrific ability of Australia’s huntsman spiders to drag dead mice up the sides of fridges</a>, they now have another reason.</p><p>They might be the fastest spiders on the planet.</p> <a href="https://www.theguardian.com/australia-news/2026/jul/09/fastest-spider-on-the-planet-brown-huntsman">Continue reading...</a>
Is the US trying to make scientists’ work so difficult that they simply give up? | Daniel Malinsky
<p>New Trump administration rules would undermine longstanding research practices. It’s death by a thousand cuts</p><p>A politician who aims to gradually privatize and ultimately destroy an institution funded by tax dollars – say, a public school system or public transportation network – may choose to do so by strategically disinvesting resources from that institution until it becomes barely functional, leading users to look elsewhere to meet their needs. Eventually, the user-base of the public system gets so low or frustrated that it seems reasonable to scrap the thing entirely, or re-direct public funds to private companies as contractors to provide the needed “service”. We’ve seen this strategy play out many times in states and city councils across America.</p><p>It appears that the endgame of the Trump administration’s attacks on science and the research funding ecosystem is similar: grant freezes and administrative disarray at federal funding agencies such as the National Institutes of Health (NIH), new layers of project review by political appointees hunting for forbidden keywords such as “disparity” and “marginalized”, and proposed new restrictions to make international collaboration difficult or impossible all point towards a world where it’s just too onerous to do federally-funded scientific research. Is the goal to make scientists simply give up on the endeavor?</p><p>Daniel Malinsky is an assistant professor of biostatistics in the Mailman School of Public <a href="https://www.theguardian.com/society/health">Health</a> at Columbia University</p> <a href="https://www.theguardian.com/commentisfree/2026/jul/11/trump-administration-scientists-rules">Continue reading...</a>

Hewing is the ancient art of cutting logs into beams or planks for timber frames.
‘Spermageddon’: is the world facing a male reproductive crisis?
<p>Reports of falling sperm counts and testosterone levels have fuelled fears over chemicals, pollution and modern lifestyles. But how much do scientists agree on what is affecting male fertility?</p><p>The world is unwittingly walking into a male reproductive crisis, scientists warned this week as they presented data that revealed an apparent <a href="https://www.theguardian.com/society/2026/jul/07/mens-average-testosterone-levels-have-halved-in-last-50-years-say-scientists">halving of average male testosterone levels</a> over the past 50 years.</p><p>“It<em> </em>is mind-blowing that testosterone has declined by 50%,” Prof Hagai Levine, who led the work, told the Guardian. “This is a lot. Wake up people. Wake up.”</p> <a href="https://www.theguardian.com/society/ng-interactive/2026/jul/11/spermageddon-world-facing-male-reproductive-crisis">Continue reading...</a>
