Letras 01:11 En la poesía borrada, se tachan partes de un texto original para crear o revelar una historia diferente intercalada en él. Que el autor inicial quisiera o no de manera deliberada este segundo mensaje es irrelevante; el hecho de que algún poeta posterior pudiese concebirlo mediante los tachados es toda la autoridad que estos escritores necesitan para sostener que la pieza descubierta siempre estuvo ahí.

A team in France has detected hydrogen dimers – one of the simplest molecular complexes – at room temperature for the first time.1 Researchers first recorded direct spectroscopic evidence of van der Waals hydrogen dimers, (H2)2, in the infrared spectrum of molecular hydrogen at 20K in 1964.2 The dimers were then detected in the atmospheres of Jupiter and Saturn in the 1980s as part of the Voyager IRIS mission.3,4 Until now, however, hydrogen dimers have only been studied at temperatures up to...

For me, queerness has always been related to imagination. Like many of us, I grew up without a blueprint for a queer life. In the evangelical household I was raised in, I had to dream my queerness into existence, conjure a life that was forbidden to me, claim it because no one was ever going to give it to me. This has been true for so many of us, now and in the past, as we’ve existed outside of and beyond the boundaries of what our world calls normal and good.

When chemists first synthesised NaBH3− back in 2019, initial research suggested a dative bond connected its sodium monoanion with a borane Lewis acid.1 Theoretical chemists, however, quickly established that the bonding was not that simple.

A new computational study adds to mounting evidence that electrophilic aromatic bromination reactions followan addition–elimination pathway and not the classic mechanism described in textbooks.1  Brominating aromatic substrates is an important step in synthesising various pharmaceuticals, pesticides, flame retardants and dyes.
