Picaflores que llegan hasta el sol

"El otro principio fue el de considerar siempre el Perú como una fuente infinita para la creación. Perfeccionar los medios de entender este país infinito mediante el conocimiento de todo cuanto se descubre en otros mundos. No, no hay país más diverso, más múltiple en variedad terrena y humana; todos los grados de calor y color, de amor y odio, de urdimbres y sutilezas, de símbolos utilizados e inspiradores. No por gusto, como diría la gente llamada común, se formaron aquí Pachacamac y Pachacutec, Huamán Poma, Cieza y el Inca Garcilaso, Túpac Amaru y Vallejo, Mariátegui y Eguren, la fiesta de Qoyllur Riti y la del Señor de los Milagros; los yungas de la costa y de la sierra; la agricultura a 4000 metros; patos que hablan en lagos de altura donde todos los insectos de Europa se ahogarían; picaflores que llegan hasta el sol para beberle su fuego y llamear sobre las flores del mundo. Imitar desde aquí a alguien resulta algo escandaloso. En técnica nos superarán y dominarán, no sabemos hasta qué tiempos, pero en arte podemos ya obligarlos a que aprendan de nosotros y lo podemos hacer incluso sin movernos de aquí mismo. Ojalá no haya habido mucho de soberbia en lo que he tenido que hablar; les agradezco y les ruego dispensarme."

Quake coincides with sky 'anomalies'?

"A preliminary analysis of the atmosphere and ionosphere over Japan in March reveals infrared and electron anomalies coincident with the Tohoku earthquake, researchers in the US and Russia claim. The anomalies are the latest evidence for a possible link between seismic activity and changes in the atmosphere or ionosphere, although sceptics believe they are unrelated."

Snake venom gets into the groove

"A few snakes do inject their venom, the rattlesnake being a well-known example. A rattlesnake's fangs are like hypodermic needles, shooting venom into prey at high pressure from a poison gland in the snake's head. But many venomous snakes and other reptiles do not have tubes in their fangs, and so cannot deliver pressurized venom. Often their fangs just have a single groove, running top to bottom."

Fermi Telescope and the dark matte- physicsworld.com

"New results from NASA's Fermi Gamma-Ray Space Telescope appear to confirm a larger-than-expected rate of high-energy positrons reaching the Earth from outer space. This anomaly in the cosmic-ray flux was first observed by the Italian-led PAMELA spacecraft in 2008 and suggests the existence of annihilating dark-matter particles. Physicists believe that about 80% of the mass in the universe is in the form of a mysterious substance known as dark matter. ... researchers are attempting to find direct evidence of it on Earth using either heavily shielded underground detectors or with particle accelerators. But they also have a third, less direct, option – using satellites or balloon-based instruments to detect the particles that some theories predict are created in space when two dark-matter particles collide and annihilate."

Telescope optics set to aid gravitational detection

"A British team is designing the optics for a telescope that will be able to detect the gravitational effects of violent cosmic events, such as when two black holes collide.
The €790m (£688m) Einstein Telescope should be completed by 2025, by which time it will be capable of detecting gravitational waves around 100 orders of magnitude fainter than current devices can."

"Oldest Textiles in South America
Textiles and rope fragments that were found 30 years ago in Guitarrero Cave in the Andes have now been dated to 10,000 BCE, making them the oldest textiles ever found in South America. ... Textile weaving took place in these caves showing that women were probably amo
ng the first to live at these altitudes in the area. The article will appear in the current issue of Current Anthropology."

Guaman Poma

Da Wikipedia.
Felipe Guaman Poma de Ayala, conosciuto anche come Guaman Poma (San Cristóbal de Suntuntu, località della provincia di Lucanas nella regione di Ayacucho, 1550 ca. – dopo il 1615), è stato un cronista indigeno del Perù durante la conquista dell'America.
 « Questo è il nostro paese, perché Dio ce lo ha dato »
Era il figlio di Guaman Mallqui e Juana Cori Ocllo Coya (ultima figlia del sovrano Túpac Yupanqui)...
Nel 1908, nella Biblioteca Reale di Copenaghen (Danimarca), fu riscoperto un antico manoscritto di 1179 pagine: la Nueva Corónica y Buen Gobierno di Felipe Guaman Poma de Ayala, di cui non si avevano più notizie da circa 300 anni. ...
Questa opera, di altissimo valore storico, aveva in origine un obiettivo concreto: ritrarre la realtà andina e sollecitare la corona spagnola ad effettuare una riforma del governo coloniale per salvare le popolazioni andine dallo sfruttamento e dai maltrattamenti. La relazione, infatti, era dedicata al re Filippo III di Spagna, ma andò smarrita durante il viaggio verso la penisola iberica. Oggi si conserva nella Biblioteca Reale di Copenaghen e si può consultare on-line.

Fossilised spider in amber

Scientists have used X-ray computed tomography to produce 3D images of a 49 million-year-old spider trapped inside an opaque piece of fossilised amber resin.

Yale Papyrus Collection

"The Yale papyrus collection began in 1889 with a gift of papyri from W. M. F. Petrie's excavations at Hawara, the archeological site in Ancient Egypt. In the following decades, Yale received a number of papyri, many of them from the discoveries at Oxyrhynchus, the ancient city west of the Nile River, by two young British excavators, Bernard Grenfell and Arthur Hunt."Yale Papyrus Collection
