this is bbc news. does the magician have any tricks left? or is bibi on his way out as prime minister of israel? the rainbow coalition to unseat the man who s lead israel for 12 years is fragile and already under pressure. benjamin netanyahu is already flexing every last inch of his political muscle, calling on his fellow right wing politiicans to block the coalition from taking office. meanwhile over in washington, the israeli defence minister holds talks with the us secretary of state, underscoring security ties between the two countries. yet another blow for the tourism industry, as the uk puts portugal on the quarantine list, upending summer holiday plans. also in the programme. the president of the japanese
soon, that was the view of the far right and the view of the mayors of the small southern towns in israel who were fired at by hamas. and also what i found his people are fed up with israeli elections and wars they want something different and maybe they ll get it. don t count him out. here in the uk, the traffic light system for countries to visit has caused a fair bit of chaos. today, airlines and travel firms have reacted with dismay to the latest government guidance on foreign holidays. travellers coming from portugal to the uk now have to quarantine again, after the uk government moved the sunny destination from the green list for foreign travel to the amber one. so now, portugal is lumped in with france, italy, spain, and greece which the government says brits should not travel to. seven countries, including costa rica, egypt, and sri lanka, were added to the red list, meaning mandatory quarantine in a uk government approved hotel. all changes to the lists will come into ef

A 3D-printed thruster that emits a stream of pure ions could be a low-cost, extremely efficient propulsion source for miniature satellites.
The nanosatellite thruster created by MIT researchers is the first of its kind to be entirely additively manufactured, using a combination of 3D printing and hydrothermal growth of zinc oxide nanowires. It is also the first thruster of this type to produce pure ions from the ionic liquids used to generate propulsion.
