Scientists besieged by polar bears in the Arctic

The image of a polar bear always arouses tenderness. Perhaps his white fur that creates the perception of purity, and the fact that usually see in zoos or photos where they pose no threat.

Very different from what is living a team of scientists in climate Vaygach station, a remote island in the Arctic north of Russia, who are besieged by a pack of five polar bears for nearly a week ago.

Bears foraging. And scientists do not have arms or equipment that allow them to drive them away, only measuring instruments useful for investigative work.

Meanwhile, the Polar Bears -how they see through the windows weigh on average 460 kilos and can reach a length of 2.40 to 2.60 meters long.

In addition, they are so agile that can get to jump a distance of 3.65 meters.

Against this, the only recourse available to the research team are emergency flares, but have failed to shake them.

The Russian government promised to help resolve the situation, the World Wide Fund for Nature (WWF or its acronym in English), one of the largest independent conservation organizations in the world reported.

It is believed that the presence of these animals in this area is caused by climate change, which has forced them to explore inland areas to stock up on food.

Meanwhile, scientists hope.

The natural territory of polar bears in the Arctic covers des Murmansk in the west to Chukotka in the east.

It is believed that the presence of these animals in this area is caused by climate change, which has forced them to explore inland areas to stock up on food.

Scholars have seen an increase in attacks on humans by bears in recent years.

Google delayed the launch of its phone parts

Google delayed their plans to test his concept of smartphone parts, called Ara Project.

Ara the first hardware project would undergo a test this year in Puerto Rico, but this has been delayed until at least next year.

The test will take place at a new location in the United States, Ara Project team informed through a series of tweets.

The team said the delay is due to "many iterations" in the design.

The Ara Project is Google's plan to create a phone parts.

This means that some components can be added or removed without the need for complex changes in the apparatus.

This would give the opportunity to "build" their own cell phone.

When the project was announced, the company said users could buy a basic structure and add modules such as keyboard, battery or other sensors.

"Immense sadness"

This could mean that the screens destroyed or used batteries would be less costly to repair and in addition this would allow others to create custom hardware for specific tasks.

Google had planned to offer 20 to 30 different test modules for Puerto Rico.

The first demonstration of the technology, the Google developer conference in May, was well received.

A forum for developers interested in working in Ara, San Francisco designer Kinsman Garrett said he felt "immense sadness" for the delay.

An app designed for astronauts

POR PROTECCION AL MENOR EL VIDEO ESTA OCULTO EN LOS ANUNCIOS, CLIC EN UNO DE ELLOS PARA VER EL VIDEO, GRACIAS

The space agency is organizing a competition with Freelancer.com in which challenge participants to design the best SmartWatch application that can be used by astronauts on the International Space Station. The best designer will receive $ 1,500.

The application requires a timer and a way to easily show the crew schedules and agendas, it is also important to send warnings or alerts if they are in danger and, above all, should allow astronauts know when the ISS is able to communicate with the control of the Earth.

The application must be compatible with the Samsung Gear 2y is important to present their ideas with images that highlight the navigation and interaction design, if you want to participate you need to register on the site Freelancer.com, the contest has left 3 weeks and 6 days and so far has 13 registered participants.

This is not the first time that NASA works with Freelancer.com, by partnering with the site in July called for new designs of tools to be used by Robonaut 2, the humanoid robot on the ISS, it is a good strategy and will also allow developers themselves known and have more opportunities.

Learn chemistry periodic table interactive Google

Periodic thetable is a staple of scientific knowledge, yet at the same time a nightmare for the memory of thousands of students. Now Google in an attempt to facilitate their learning has created an interactive table for those complicated chemistry classes.

The periodic table is one of the most important discoveries of science. Usually it attributed to Dmitri Mendeleev, who ordered the elements of the table by placing atomic mass and common properties among them.

Currently the advancement of technology has made more intuitive and visual learners who prefer to learn by experimentation rather than governed by traditional education. Why and to prevent their study cumbersome, deGoogle inventions sector, has created interactive periodic ThisTable.

Inspired by a diagram that reflects the relative abundance of the elements, the display created by Google lets you decide if you want to see the size of the elements according to the share they hold in the body, the sun, the sea, the earth's crust, the number of times mentioned in the literature and to the volume (cubic centimeters per gram measured).

Interactivity also allows viewing in bars, blocks or electrons, allowing you to see the atomic structure of the same. Surely a useful tool for this coming back to classes that will definitely make laquímica see another perspective.

GOOGLE CREATED ITS OWN AUTOMOTIVE

Some company cars are still the focus of attention of those in Silicon Valley and California in general. But unlike the majority assumes, there is Google, but Google Auto LLC. According to research conducted by The Guardian, the company emerged in 2011 as a result of replacing Google Prius used cars by Lexus SUV he works today.

Google Auto LLC was established as a limited liability company. Its director is Chris Urmson, project leader who is conducting the company to make cars that run themselves. The company is listed as the owner of the 23 Google intelligent vehicles.

According to an expert consulted by the English news site, this move could find its logic on the need for the company directed by Larry Page to legally protect themselves against possible accidents caused in testing Google Car. It was also Google the company Auto LLC He made the request for the identification number for each car project.

In a major automotive event held in the United States in January, he reported Urmson enter into dialogue with General Motors, Toyota, Ford, Daimler and Volkswagen. To date, no agreement with any of these companies was informed by Google or Google Auto LLC.

Erreur humaine causée ACCIDENT SHIP

The researchers reported Tuesday that the accident at the Virgin Galactic of 9 months was caused by a structural failure after the copilot unlock the brakes too early.

The National Board of Transportation Safety (NTSB, for its acronym in English) of the United States determined that the resulting aerodynamic forces caused the brakes were deployed, which destroyed the spacecraft SpaceShip Two.

The NTSB has been investigating what had caused the spacecraft broke over the Mojave Desert on a test flight nine months ago.

The ship was launched with the aircraft WhiteKnightTwo, which separated smoothly to fly independently. Moments later, the SpaceShipTwo crashed.

In the accident died the copilot Michael Alsbury. The pilot was seriously injured.

Human factors

The ship for tourist Virgin Galactic space flight was on a manned test flight last October 31 when he suffered what the company described at the time as a "serious anomaly".

The founder of Virgin Group Sir Richard Branson British after the accident said he was "shocked and saddened" by the "tragic loss."

The chairman of the NTSB, Christopher Hart, said Tuesday he expects the investigation to avoid similar accidents from occurring, adding that the security agency came to know "with a high degree of certainty the events that led to the rupture."

"Many of the security issues that we discussed today emerged not because of the novelty of the launch of a space test flight but by human factors known in other areas of the world of transport," he said.

Both drivers were hired by Scaled Composites, the company that designed the ship.

ILEGAL EXPORT AND MONEY

El atacante tunecino que atacó un complejo hotelero el viernes matando a 39 personas, la mayoría turistas británicos, probablemente pasó un tiempo un campo de entrenamiento en Libia y había estado en contacto con los militantes en la frontera, dijo una fuente de seguridad el martes.

El ataque contra el hotel de playa Imperial Marhaba en la popular ciudad turística de Sousse se produjo apenas meses después de que militantes atacaron el museo del Bardo en Túnez, matando a 21 personas, y la entrega de un golpe a la industria turística vital.

Los investigadores estaban verificando si el pistolero, un estudiante Saif Rezgui, había recibido entrenamiento de militantes en un campamento yihadista a través de Libia. Las autoridades también han detenido a otras tres personas por ayudar a planear el ataque, dijo una fuente de seguridad.

"Las investigaciones muestran Saif Rezgui estaba en contacto con los terroristas en Libia y lo más probable es entrenado en un campamento de Libia", dijo a Reuters una fuente oficial.

Libia, atrapado en una batalla de varios lados entre dos gobiernos rivales y sus facciones armadas, se ha convertido en un objetivo para los partidarios del Estado islámicos y otros grupos yihadistas que se han aprovechado del caos de seguridad.

Los dos hombres armados que llevaron a cabo el ataque de marzo en el Bardo también habían cruzado clandestinamente en Libia para el entrenamiento a finales del año pasado, dijeron los investigadores. Rezgui había sacado su pasaporte el año pasado, pero no había sellos de salida en el mismo, dijeron las autoridades.

El atacante Sousse, que había mostrado pocas señales de radicalización por los reclutadores islamistas fundamentalistas, fue muerto a tiros por la policía fuera del hotel.

La masacre fue el peor de su tipo en Túnez, uno de los países más seculares del mundo árabe, que ha sido elogiado por su transición a la democracia después de un levantamiento de 2011.

Túnez espera perder al menos 515 millones dólares este año, o alrededor de una cuarta parte de sus ingresos del turismo estimados anuales, tras el ataque del viernes pasado.

"El ataque tuvo un gran impacto en la economía, las pérdidas será grande", dijo el ministro de Turismo Salma Loumi periodistas la noche del lunes, dando una estimación preliminar del ataque Sousse.

El país del norte de África se ganó $ 1,95 mil millones en los ingresos provenientes del turismo el año pasado. El sector representa el siete por ciento de su producto interno bruto y es una importante fuente de divisas y de empleo para Túnez.

Loumi dijo que el gobierno planea poner fin a impuesto de visitantes y también para opinar sobre alivio de la deuda para los operadores de hoteles como formas de ayudar a sostener la industria.

El gobierno ha dicho que 1000 policías turísticos más armados patrullarán los hoteles y sitios turísticos y las reservas del ejército también se elaboró ​​para reforzar la protección.

Elogiado por su nueva Constitución, las elecciones libres y la política de compromiso después de que el 2011 levantamiento para derrocar autócrata Zine El-Abidine Ben Ali, Túnez también ha tenido problemas con el auge de los movimientos islamistas fundamentalistas que floreció a principios del caos.

Algunos de esos grupos se volvieron a la violencia y las fuerzas armadas de Túnez han estado luchando escaramuzas ocasionales con militantes islamistas locales cerca de la frontera con Argelia.

Pero más de 3.000 tunecinos también han dejado de luchar por grupos islamistas militantes en Siria, Irak y Libia, y algunos han amenazado con volver a llevar a cabo ataques en su patria.
