Running = No cancer

Alguna vez escuche a algún bobalicón decir que correr es deporte para pobres. Era uno de esos ignorantes presuntuosos que ven al deporte como otro trending topic, que hacen el Insanity por 3 días y lo dejan, que solo pueden correr 5 kms si les dan una medalla, o que creen que tener que una vida sana equivale a pagar un GYM de 1500 mensuales.

Hoy me encontré este bonito estudio sobre los nuevos beneficios de correr, entre los que se encuentran la producción de células inmunes al cáncer, pues favorece a crear el ambiente propicio para que estas células se desarrollen mejor y sean más fuertes.

Pobre del bobalicón, pensé por segunda vez…

Running is also great for holding off cancer. We know well enough that regular physical exercise can limit the development and recurrence of cancer, and there has been evidence that it can improve outcomes and functional capacity in cancer patients even to the point of suppressing tumors, but the mechanisms behind this have been murky. This is where a new study in the journal Cell comes in, describing not just the tumor-limiting effects of voluntary running in mice, but also how that limiting actually happens via the activation of immune cells known as NK or “natural killer” cells, a type of lymphocyte or white blood cell whose function is all in the name…

Van Gog’s ear

No, este posteo no tiene nada que ver con el horrible grupo musical del mismo nombre.

Superado eso, sigo. El artitsa holandés Diemut Strebe acaba de utilizar ADN real de un descendiente lejano del famoso pintor post-impresionista (su tatara-tatara-nieto, parece), en una extraña pieza mezcla de arte y genética llamada “Sugababe”, donde hizo “crecer” de nuevo la igualmente famosa oreja cercenada. No diré mas…

Using cells from van Gogh’s distant relative Lieuwe van Gogh, the ear of Vincent Van Gogh has been regrown by Dutch artist Diemut Strebe, who uses “science basically like a type of brush.” After growing enough
cells from the material obtained from the great-great-grandson of
Vincent’s brother Theo, they were shaped to replicate van Gogh’s
detached organ using a 3D printer and the resulting “ear” is being kept
alive using a nutrient solution. Lieuwe shares around a sixteenth of the
same genes as the Impressionist master, which includes the Y-chromosome
passed down through the male lineage…

Seething

Básicamente, células reproducíéndose; un video musical de Andy Lomas para el músico electrónico Max Cooper. Como su propio creador lo describe, “una versón musical de la intensidad humana”…

British digital artist Andy Lomas has created a virtual model of cellular growth, allowing us to watch as intricate bio-inspired sculptures slowly take shape. Recently, he collaborated with techno-producer Max Cooper to create a music video titled Seething, named for the unstoppable and unrelenting propagation of life…

Descubren una proteína que puede revertir el envejecimiento

Unos científicos acaban de dar un pequeño paso en esa eterna batalla  contra la muerte, o al menos en nuestro intento por prolongar la vida. Vean lo que acaban de descubrir en la Universidad de Harvard, sobre una proteína llamada SIRT1…

A protein in blood can repair age-related damage in the brains and muscles of old mice, returning them to a more youthful state.

Last year, the protein, called growth differentiation factor 11 (GDF11), was found to have a restorative effect on mouse hearts. If it does a similar job in humans, it could have huge potential for treating a wide-range of age-related diseases, say the researchers behind the latest work…
