Så anpassade sig atlantsillen till Östersjöns bräckta vatten
<p>&#xD6;stersj&#xF6;n har funnits i cirka 8 000 &#xE5;r och relativt tidigt tog sig sillen in fr&#xE5;n Atlanten. Sillen &#xE4;r en av ganska f&#xE5; atlantfiskar som har lyckats anpassa sig till &#xD6;stersj&#xF6;ns l&#xE5;ga salthalt. Hindret f&#xF6;r atlantfiskar &#xE4;r att de ska kunna leka och f&#xF6;r&#xF6;ka sig n&#xE4;r salthalten &#xE4;r dramatiskt l&#xE4;gre &#xE4;n i Atlanten.

Do we judge people by the way they sound? How accents shape our lives
<p>A new book by linguistics professor Valerie Fridland, who was raised in Memphis by parents with French accents, explores the power behind the way we speak</p><p>Valerie Fridland writes in her new book, Why We Talk Funny: the Real Story Behind Our Accents, that humans instinctively use accents to categorize those around us. “We learn to recognize other people as being like us through the way that they sound,” Fridland says. It happens early: studies suggest small children, when choosing friends, favor those who share their accent.</p><p>In <a href="https://www.apa.org/news/press/releases/2019/01/kids-accents">one study</a>, for instance, five- and six-year-olds were shown pairs of kids on a computer screen, one with a local Canadian accent and one with a British accent. Asked who they wanted to be friends with, they picked the kid with the local accent – even though they lived in Toronto and are exposed to a huge range of accents every day.</p><p>Then said they unto him, Say now Shibboleth: and he said Sibboleth: for he could not frame to pronounce it right. Then they took him, and slew him at the passages of Jordan</p> <a href="https://www.theguardian.com/science/2026/may/13/valerie-fridland-linguistics-accents">Continue reading...</a>
