Un albero genealogico pu\u00f2 essere basato praticamente su qualsiasi caratteristica desiderata dallo scienziato.

Ma se anche altre cose potessero avere il DNA? Diciamo che anche le stelle potrebbero essere analizzate in base al loro DNA e persino ottenere un proprio albero genealogico.<\/p>\n<p>Questa discussione \u00e8 iniziata con due scienziati: un astronomo e un biologo. L'astronomo, <a href=\"https:\/\/academic.oup.com\/mnras\/article\/2966869\/Cosmic\">\u00a0Dott.ssa Paula Jofr\u00e9 dell'Universit\u00e0 di Cambridge<\/a>ha avuto la straordinaria idea di analizzare le stelle come i biologi fanno con le specie animali e di costruire l'albero genealogico delle stelle della Via Lattea.<\/p>\n<p><iframe loading=\"lazy\" title=\"Gli astronomi hanno creato un albero genealogico delle stelle della nostra galassia\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/HZq1dLuhjMg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<p>La dottoressa Paula Jofr\u00e9 e il suo team hanno scelto 22 stelle (compreso il Sole) e hanno studiato le sostanze chimiche di cui sono composte, la loro et\u00e0 e il loro movimento. Una volta raccolto tutto questo, hanno scoperto tre rami principali in cui le stelle potevano essere divise.<\/p>\n<p>Ma cosa c'entra il DNA con tutto questo?<\/p>\n<p>Le stelle nate nella stessa nube di gas hanno una composizione simile. Questa composizione \u00e8 chiamata \"DNA stellare\". Poich\u00e9 alcune stelle analizzate non avevano un DNA stellare simile ai tre rami scoperti, \u00e8 possibile che alcune stelle provengano da una galassia diversa. Queste stelle potrebbero essere state assorbite dalla Via Lattea e non avere stelle sorelle.<\/p>\n<p><a href=\"https:\/\/academic.oup.com\/mnras\/article\/2966869\/Cosmic\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-6714 size-full\" src=\"https:\/\/blog.mindthegraph.com\/wp-content\/uploads\/2017\/03\/preview-1424544235.jpg\" alt=\"Parliamo di stelle che hanno un albero genealogico\" width=\"719\" height=\"464\" srcset=\"https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2017\/03\/preview-1424544235.jpg 719w, https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2017\/03\/preview-1424544235-300x194.jpg 300w\" sizes=\"(max-width: 719px) 100vw, 719px\" \/><\/a><\/p>\n<p>Si tratta, ovviamente, solo di un'intuizione.

Quindi s\u00ec, sono necessarie ulteriori ricerche per iniziare a fare ipotesi.<\/p>\n<p>Tuttavia, il messaggio che traiamo da questa ricerca \u00e8 forte e chiaro: non abbiate paura di imparare da campi di studio diversi. Forse la soluzione ai vostri problemi o semplicemente un modo migliore di vedere le cose pu\u00f2 essere proprio accanto a voi.
