内容摘要：Smart phones have largely been a bit of a buzzkill for horror films, leading filmmakers to find all kinds of reasons — dead batteries, no service — to strand potential prey. But at least since 1949’s “Sorry, Wrong Number,” phones have also been a reliable conduit for terror capable of reaching into the home, or your pocket. “Drop,” a silly but suspenseful new thriller, carries on the tradition of “When a Stranger Calls” and “Phone Booth” by situating its tension around mysterious, threatening phone messages.

Smart phones have largely been a bit of a buzzkill for horror films, leading filmmakers to find all kinds of reasons — dead batteries, no service — to strand potential prey. But at least since 1949’s “Sorry, Wrong Number,” phones have also been a reliable conduit for terror capable of reaching into the home, or your pocket. “Drop,” a silly but suspenseful new thriller, carries on the tradition of “When a Stranger Calls” and “Phone Booth” by situating its tension around mysterious, threatening phone messages.

O podría ser “algo exótico” y desconocido, dijo Wang, autor principal del estudio publicado en la revista Nature.El Observatorio de Rayos X Chandra de la NASA detectó las emisiones de rayos X por casualidad el año pasado mientras se enfocaba en un remanente de supernova, o los restos de una estrella explotada. Wang dijo que era la primera vez que se veían rayos X provenientes de un llamado transitorio de radio de largo período, un objeto raro que cicla a través de señales de radio durante decenas de minutos.

Dada la distancia incierta, los astrónomos no pueden determinar si el extraño objeto está asociado con el remanente de supernova o no. Un solo año luz equivale a 5,8 billones de millas.La fase hiperactiva de este objeto —designado ASKAP J1832−091— pareció durar alrededor de un mes. Fuera de ese período, la estrella no emitió rayos X notables. Eso podría significar que hay más de estos objetos por ahí, indicaron los científicos.“Aunque nuestro descubrimiento aún no resuelve el misterio de qué son estos objetos e incluso puede profundizarlo, estudiarlos nos acerca a dos posibilidades. O estamos descubriendo algo completamente nuevo, o estamos viendo un tipo conocido de objeto emitiendo ondas de radio y rayos X de una manera que nunca hemos observado antes”, afirmó Wang.

Lanzado en 1999, Chandra orbita a decenas de miles de kilómetros (millas) sobre la Tierra, observando algunos de los objetos más calientes y de alta energía en el universo.___________________________________

___________________________________One way to shift the trade in goods would be for Europe to buy more liquefied natural gas by ship from the U.S. To do so, the EU could cut off the remaining imports of Russian pipeline gas and LNG. The commission is preparing legislation to force an end to those purchases -- last year, some 19% of imports — by the end of 2027.

That would push European private companies to look for other sources of gas such as the U.S. However the shift away from Russia is already in motion and that “has obviously not been enough to satisfy,” said Laurent Ruseckas, a natural gas markets expert at S&P Global Commodities Insights Research.The commission doesn’t buy gas itself but can use “moral suasion” to convince companies to turn to U.S. suppliers in coming years but “this is no silver bullet and nothing that can yield immediate results,” said Simone Tagliapietra, an energy analyst at the Bruegel think tank in Brussels.

Europe could buy more from U.S. defense contractors as part of its effort to deter further aggression from Russia after the invasion of Ukraine, says Carsten Brzeski, global chief of macro at ING bank. If European countries did increase their overall defense spending — another of Trump’s demands — their voters are likely to insist that the purchases go to defense contractors in Europe, not America, said Stokes of the German Marshall Fund. One way around that political obstacle would be for U.S. defense companies to build factories in Europe, but “that would take time,’' he said.The EU could also reduce its 10% tax on foreign cars— one of Trump’s long-standing grievances against Europe. “The United States is not going to export that many cars to Europe anyway ... The Germans would be most resistant, but I don’t think they’re terribly worried about competition from America,’' said Edward Alden, senior fellow at the Council on Foreign Relations. ”That would be a symbolic victory for the president.’'
