Hola lectores de Nature, hoy nos deleitamos con las primeras cinco imágenes científicas a todo color tomadas por el Telescopio Espacial James Webb, consideramos si los gophers cultivan sus túneles y exploramos por qué fallan algunos despliegues de vacunas.

Webb capturó el Quinteto de Stephan, un grupo de galaxias que están interactuando entre sí, desencadenando el nacimiento de estrellas en una intrincada danza cósmica. Webb ve la luz infrarroja, por lo que puede atravesar el sudario de polvo que rodea una galaxia, revelando la velocidad y la composición del gas cerca del agujero negro supermasivo en el centro. (NASA, ESA, CSA y STScI)

Primeras imágenes del telescopio Webb El Telescopio Espacial James Webb, una colaboración entre la NASA, la Agencia Espacial Europea y la Agencia Espacial Canadiense, publicó hoy cuatro de sus primeras imágenes científicas a todo color. El espejo de 6,5 metros de ancho de Webb es el más grande jamás lanzado al espacio. La combinación de su gran espejo, vista infrarroja y punto fresco y sombreado en la cara oculta de la Luna permiten a Webb una vista sin precedentes de muchos fenómenos astronómicos. "Es solo el comienzo", señala la astrónoma de la NASA Michelle Thaller. Naturaleza | 5 min de lectura

El borde de una región joven de formación estelar llamada NGC 3324 en la Nebulosa Carina podría traer a la mente una imagen evocadora tomada por el Telescopio Espacial Hubble. La imagen de Webb revela por primera vez áreas previamente invisibles de nacimiento de estrellas. (NASA, ESA, CSA y STScI)

The Southern Ring Nebula is a glowing shell of gas and dust that was ejected by a star near the end of its life. Two images from Webb, taken in slightly different ranges of infrared light, show extraordinary detail in the gas rippling around the central star. (NASA, ESA, CSA, and STScI)

The first image released today captures the spectrum of the steamy atmosphere of a hot gas giant exoplanet, WASP-96b. The spectrum shows the distinct signature of water and evidence of clouds and haze. (NASA, ESA, CSA, and STScI)

US President Joe Biden gave us a sneak peak of Webb’s wonders by releasing its first science image yesterday. It is the deepest astronomical image of the distant Universe and shows thousands of galaxies in a patch of sky no larger than that covered by a grain of sand held at arm’s length.

Gophers are ‘farmers’ too, say scientists Gophers graze on roots that grow into their large network of tunnels, which some researchers say could be the first evidence of a non-human mammal engaging in farming. Scientists installed cameras in trenches that they dug around tunnels used by southeastern pocket gophers (Geomys pinetis) in Florida. The roots of above-ground grasses and nettles quickly filled the tunnels that the gophers couldn’t access, but remained short in those they could. The animals nibbled on the roots to nourish themselves and stimulate root regrowth, and dropped waste throughout the network to fertilize the soil — effectively cultivating the crop. Other researchers say the practice can’t be described as farming because the gophers don’t plant or distribute their crops as do humans and other creatures, such as fungus-growing ants.

A case study of a failed vaccine roll-out Researchers have been studying vaccine hesitancy in Guatemala, which has one of the lowest COVID-19 vaccination rates in Latin America. Only about 35% of people have been fully vaccinated. “It’s incredibly difficult to convince them,” says nurse Nancy Notz, who took to the streets with colleagues and a megaphone to publicize the availability of the life-saving shots. The underlying reasons are complicated. Trust is a factor in a country with a history of human-rights abuses against Indigenous communities and ethical violations by medical authorities in the past few decades. Twenty-five languages are spoken in Guatemala — but most educational information was first published in Spanish. And there are financial barriers for some people who must travel far to vaccination sites. Nature | 7 min read

‘Quantum-proof’ algorithms guard the keys Future quantum computers might be able to break the cryptographic keys that protect everything from smartphone banking apps to online payments. Now, the US National Institute of Standards and Technology has officially endorsed cryptographic technologies that are thought to be resistant to attack from quantum computers. These include an encryption algorithm — used to keep online data secure — called CRYSTALS-Kyber, along with three algorithms for use in digital signatures, which provide identity authentication. “It’s officially a post-quantum world,” says John Graham-Cumming, chief technology officer of the Internet-services company Cloudflare.

Research highlights: 1-minute reads for Nature subscribers Wild rock doves have a smaller cere — the lighter bit at the base of the upper bill — and a more-vertical forehead. They also have a beak that is thinner and longer than that of the average city pigeon, whose bill is relatively chunky. (W. J. Smith et al./iScience) Found: Hideout of primordial pigeons The nineteenth-century rage for pigeon breeding created a wealth of fantastical varieties of pigeon (Columba livia), seeding the world with escaped domestic birds and their feral descendants, which hybridized with their wild ancestors, the rock doves. Researchers have now combed the British Isles, using genome sequences and physical inspection, for rock doves lacking significant influence from domestic genes — and they found some, on Scotland’s Outer Hebrides island chain. These birds showed “negligible” genetic mixing with their sandwich-crust-nibbling feral kin.

QUOTE OF THE DAY “I am so thrilled and so relieved. This was so hard and we took so long.” John Mather, senior Webb project scientist, rounds up the announcement of the long-awaited first images from the telescope, which took more than 30 years and US$11 billion to develop. (Nature | 7 min read)

Hoy finalmente puedo colgar mis ganchos y poner los pies en alto para disfrutar de las primeras imágenes del telescopio espacial Webb. Podría comenzar con el anunciado ayer, que se arremolina con miles de galaxias en un pequeño parche de cielo. Experimente lo pequeño que es con el Telescopio Mundial de la Sociedad Astronómica Americana, que le permite explorar la imagen en resolución completa, superpuesta en un mapa virtual del cielo. Hágame saber qué imagen de Webb es su favorita, adivina cuál hizo que nuestro experimentado corresponsal espacial dijera "¡Eeeeeeeeee!" y comparta cualquier otro comentario sobre este boletín en briefing@nature.com.

Hello Nature readers, Today we revel in the first five full-colour science images taken by the James Webb Space Telescope, consider whether gophers farm their tunnels and explore why some vaccine roll-outs fail.

Webb captured Stephan's Quintet, a group of galaxies that are interacting with one another, triggering star birth in an intricate cosmic dance. Webb sees infrared light, so it can pierce through the shroud of dust surrounding a galaxy, revealing the velocity and composition of the gas near the supermassive black hole at the centre. (NASA, ESA, CSA, and STScI)

First images from Webb telescope The James Webb Space Telescope — a collaboration between NASA, the European Space Agency and the Canadian Space Agency — released four of its first full-colour science images today. Webb’s 6.5-metre-wide mirror is the largest ever launched into space. The combination of its large mirror, infrared view and cool, shady spot on the far side of the Moon allow Webb an unprecedented view of many astronomical phenomena. “It’s only just the beginning,” notes NASA astronomer Michelle Thaller.

The edge of a young, star-forming region called NGC 3324 in the Carina Nebula might bring to mind an evocative image taken by the Hubble Space Telescope. Webb’s image reveals for the first time previously invisible areas of star birth. (NASA, ESA, CSA, and STScI)

The Southern Ring Nebula is a glowing shell of gas and dust that was ejected by a star near the end of its life. Two images from Webb, taken in slightly different ranges of infrared light, show extraordinary detail in the gas rippling around the central star. (NASA, ESA, CSA, and STScI)

Today I can finally hang up my tenterhooks and put my feet up to enjoy the first images from the Webb space telescope. I might start with the one announced yesterday, which swirls with thousands of galaxies in a tiny patch of sky. Experience just how tiny with the American Astronomical Society’s WorldWide Telescope, which allows you to explore the image in full resolution, overlaid on a virtual sky map. Let me know which Webb image is your favourite, guess which one made our seasoned space correspondent say “Eeeeeeeeee!” and share any other feedback on this newsletter at briefing@nature.com.
