Scientists warn of possible solar storm in 2014.

An expert panel found that this phenomenon, more and more common, occur within the next two years and may affect global electrical systems and satellites in orbit.

Usually we are used to understand the concept of "natural disaster" in phenomena such as earthquakes, volcanoes, tidal waves and tsunamis. However, a group of NASA scientists warned of an event that is still contingency plans in the world, solar storms.

Solar storms are phenomena which have been heard enough in recent times but could increase with the years.

The panel found that by 2014 the world will face a wave could affect solar electricity systems, communications and satellites around the world.

This could be the biggest event in a cycle of 10 years in the activity of the star and, if filed, would be the first in more than 100 years.

Among the possible consequences that could cause the magnetically charged plasma on earth, is the melting of the electrical transformers in the world, damage satellites and communication systems.

The last solar storm of this magnitude occurred in 1859. At the time, the British astronomer Richard Carrington observed the large solar flare and timed the arrival of geomagnetic storms caused by the phenomenon to Earth with a delay of about 17 hours.

According to reports at the time, the solar storm was so massive that formed northern lights that could be seen much further south than where they usually are.

The question that remains for NASA experts is what the actual impact of a storm of this nature, taking into account the number of satellites in orbit and the effects of their damage globally.

Adiòs a la caries dental, Cientìficos chilenos crean substancia que eliminan las bacterias.

Científicos chilenos desarrollaron Keep32, una sustancia que elimina las bacterias que erosionan los dientes. Podría añadirse a productos de higiene e, incluso, a alimentos

Los especialistas José Córdova, de la Universidad de Yale, y Erich Astudillo, de la Universidad de Chile y CEO de Top Innovations Tech, crearon un compuesto que permitiría decirle adiós a las visitas al dentista.

La sustancia bautizada Keep 32, en honor a los 32 dientes que tiene toda persona, elimina todas las bacterias que causan las caries en tan sólo 60 segundos y su dosis protege a la boca durante horas.

Según sus inventores, puede ser agregada a cualquier producto para la higiene dental como pasta de dientes, enjuagues bucales y goma de mascar. Incluso, creen que podrá añadirse a alimentos de consumo diario.

Keep 32 fue sometido a pruebas durante siete años y podría estar en el mercado en 14 o 18 meses, afirmaron Córdova y Astudillo, quienes esperan recibir la patente para vender la licencia a grandes empresas químicas como Procter & Gamble.

Good Bye to dental caries, Chileans scientists created a substance that kills bacterias.

Specialists Jose Cordova, Yale University, and Erich Astudillo, University of Chile and CEO of Top Tech Innovations, created a compound that would say goodbye to dentist visits.

Keep 32 the substance was named in honor of the 32 teeth of every person, kills all the bacteria that cause cavities in just 60 seconds and a dose protects the mouth for hours.

According to its inventors, can be added to any product for dental hygiene such as toothpaste, mouthwash and chewing gum. Even, believe it may be added to food daily.

Keep 32 was tested for seven years and could be on the market in 14 or 18 months, and Astudillo said Cordova, who expect to receive a patent license to sell the large chemical companies such as Procter & Gamble.

Chile: Astronomers find evidence of dark galaxies.

Chile: Astronomers find evidence of dark galaxies.

Astronomers in Chile using a powerful telescope have observed what appears to be evidence of the existence of dark galaxies, the European Southern Observatory (ESO) announced Wednesday.

Dark galaxies are small, gas-rich galaxies from the early universe that are believed to be the building blocks of today's bright, star-filled galaxies, said the ESO, an intergovernmental organization supported by 15 countries.

"For the first time, dark galaxies -- an early phase of galaxy formation, predicted by theory but unobserved until now -- may have been spotted," the ESO said in a statement.

"Using ESO's Very Large Telescope, an international team thinks they have detected these elusive objects by observing them glowing as they are illuminated by a quasar," it said.

The ESO is the most advanced astronomical observatory in the world, and operates three sites in Chile.

The Very Large Telescope (VLT) array -- a cluster of four telescopes that can view objects four billion times fainter than objects visible to the naked eye -- is housed at the ESO's Paranal site in Chile's Atacama Desert.

"Our approach to the problem of detecting a dark galaxy was simply to shine a bright light on it," researcher Simon Lilly said in the release.

"With this study, we've made a crucial step towards revealing and understanding the obscure early stages of galaxy formation and how galaxies acquired their gas," added his colleague, Sebastiano Cantalupo.

The ESO is supported by Austria, Belgium, Brazil, Britain, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden and Switzerland.

Chile: A cost and energy efficient water purifying system brings clean water to the poor.

 A cost and energy efficient water purifying system being used in a Chilean camp could one day provide safe drinking water for millions of people in the developing world. Created by Chilean scientists, the system cleans contaminated water by blasting it with ionized particles making it safe to drink.
