Nos encontramos con este destacado artista visual, quien vino, junto con Sebastián González y Tono Cruz, a la región de Magallanes, invitados por el Festival Cielos del Infinito.
Habla de su presencia en Magallanes, tanto en Puerto Natales como en Punta Arenas y destaca que es parte de una gira artística nacional, para descentralizar la cultura y que ha significado todo un período de aprendizaje de lo que son nuestras raíces y nuestra identidad.
Entrega su opinión sobre lo que está sucediendo en nuestro país, a partir del 18 de octubre. Recalca que nos estamos encontrando con un lenguaje popular visual y que hay que poner atención a lo que está sucediendo.
Habla también de su proyecto con Mon Lafert, que es el de pintar en Viña del Mar, durante el mes de abril, en la población donde ella nació. En ese mes también pintarán con otros muralistas, en La Reina, un mural sobre Violeta Parra. También entrega algunos antecedentes de sus proyectos internacionales, tanto en Francia como en Italia.
Recién llegado de Puerto Natales conversamos con el artista visual Sebastián González sobre el mural realizado en conjunto con los artistas visuales Tono Cruz y Alejandro Mono González en esa ciudad y que está dentro de las actividades que ha organizado el Festival Cielos del Infinito
Penguins are social animals; they travel, feed, breed, nest, and simply follow large groups.
"The penguin effect" is a psychological term, suggesting that penguins (and humans too, apparently) wait for one individual to start doing something, and then they all follow, sometimes with disastrous consequences.

Marine biologists are flying a bespoke mini-submarine under the sea ice to explore environments around Davis research station that have never been seen before.
In the frozen fjords of Vestfold Hills, Dr Jonny Stark and Dr Glenn Johnstone are surveying benthic (bottom-dwelling) life as part of the environmental assessments for the proposed Davis aerodrome.
The Australian Antarctic Division scientists are visiting up to 30 sites to deploy the 35 centimetre wide Remotely Operated Vehicle (ROV) that carries three cameras.
“One of the most exciting aspects that we’re drilling holes through more than a metre of sea ice, popping this thing through, and we just don't know what we're going to find,” said Dr Johnstone just before deploying the ROV into Long Fjord, north of Davis research station.
The study is trialling systematic ways to survey the sea floor with cameras and develop methodologies for a long-term monitoring program.
“We also want to investigate suitable sites that we could survey routinely if the proposed aerodrome goes ahead,” said Dr Stark.
“It’s important to know what’s here and its status, for example, we just don’t know if most of the life on the sea-floor is threatened, vulnerable, rare or unique, or is it pretty common? We have no idea about those kinds of questions.”
Work in the 1980s along one of the fjords found extensive polychaete (tubeworm) reefs stretching up to eight kilometres in length.
“The worm reefs are made of tubes of calcium carbonate, the same material that coral reefs are made out of,” Dr Stark said.
“We have reconfirmed that those reefs are still there. These preliminary surveys have indicated they look pretty healthy. They stretch from the surface down to 30 metres, much like coral does really.”
Dr Johnstone said that the types of organisms living on the seafloor – such as crustaceans, sea squirts, sponges, starfish, and sea urchins - are similar to those on reefs in Tasmania or Southern Australia.
“However, they occur here as different species in different communities. All of the organisms here are endemic to Antarctica.”
The surveys are finding a diversity of habitats with high variation across small areas, depending on currents, slope of the seafloor, and thickness of sea ice.
“When I was a kid I always wanted to be an explorer, and here I am, exploring an unknown environment,” said Dr Stark.
“The fjords, particularly around Davis, are extensive biodiversity hotspots and we know barely anything about them.”

La nueva especie, bautizada como Tralkasaurus cuyi, es mucho más pequeña que los dinosaurios carnívoros del grupo de los terópodos abelisaurios conocidos hasta ahora. Medía alrededor de cuatro metros y fue hallada al noroeste de la provincia de Río Negro, a 25 kilómetros de El Chocón.
La Antártida registró este mes temperaturas superiores a los 20 ºC, algo "nunca visto" en el continente blanco, dijo el jueves a la AFP el científico brasileño Carlos Schaefer, que realizó sus mediciones en la isla Marambio (o Seymour).
Complex lake systems around the proposed site of the Davis aerodrome are being intensively studied by scientists from the Australian Antarctic Division (AAD).
The Vestfold Hills is the location of Davis research station and the proposed aerodrome, and has hundreds of lakes of various sizes and salinities.
This research will determine whether there are unique communities in the area of the proposed aerodrome area, and how similar they are to communities found elsewhere in the Vestfold Hills

Complex lake systems around the proposed site of the Davis aerodrome are being intensively studied by scientists from the Australian Antarctic Division (AAD).
The Vestfold Hills is the location of Davis research station and the proposed aerodrome, and has hundreds of lakes of various sizes and salinities.
Leader of the lakes team, AAD ecotoxicologist Dr Catherine King, said each water body is likely to have different chemical and physical properties, which may be home to distinct biological communities.
“Our program is looking at a range of lakes of different sizes and salinities, and studying the biological communities and how diverse they are,” said Dr King.
Along with water samples, Dr King and Dr Kathryn Brown are collecting soil and sediment samples from the base of each lake or pond, at the water’s edge, and at varying distances from each site.
“We’re looking at what occurs in the soil community as you progress along a moisture gradient out from each lake, or alternatively, from one lake to another.”
“And whether there’s any connectivity or differences between lakes that we might need to be particularly careful about protecting,” Dr King said.
One of the unique characteristics of the Vestfold Hills are meromictic lakes, where the water column is stratified into layers of varying density ranging from freshwater to hypersaline.
“Vestfold Hills has the largest concentration of meromictic lakes on the planet,” Dr King said.
“Between the layers you get very different chemistry, as well as very different biological communities.”
A part of their sampling, the lakes team will tow nets to capture plankton, using inflatable boats to access the larger lakes.
Most of the samples will be analysed by microscopy back in Australia to identify microalgae and micro-invertebrates.
Broader community composition will also be assessed by DNA sequencing of water, algae, and soil samples.
This research will determine whether there are unique communities in the area of the proposed aerodrome area, and how similar they are to communities found elsewhere in the Vestfold Hills.
