(Reuters) - United Parcel Service Inc ( UPS.N ) said on Tuesday it is buying 125 Tesla Inc ( TSLA.O ) all-electric semi-trucks, the largest known order for the big rig so far, as the package delivery company expands its fleet of alternative-fuel vehicles. Tesla is trying to convince the trucking community it can build an affordable electric big rig with the range and cargo capacity to compete with relatively low-cost, time-tested diesel trucks. This is the largest public order of the big rig so far, Tesla said. Tesla unveiled its semi last month and expects the truck to be in production by 2019. The Tesla trucks will cost around $200,000 each for a total order of about $25 million. UPS expects the semi-trucks, the big rigs that haul freight along America's highways, will have a lower total cost of ownership than conventional vehicles, which run at about $120,000. Tesla has received pre-orders from such major companies as Walmart ( WMT.N ), fleet operator J.B. Hunt Tra

Apple  has released its most powerful computer ever. The iMac Pro looks like the traditional computer that hasn't changed in years, except with a darker, space grey finish. But inside it has been completely revamped, with Apple redesigning the inside of the Mac so that it can shove more processing power and other guts inside. The computer has gone on sale today, and will begin at £4,999, though all sorts of expensive additions can be added to get it all the way to top speed. Users can pay for a processor with a full 18 cores, for instance, if they're unhappy with the already incredibly fast 8-core processor that comes in the base model. The computer was first unveiled at Apple's Worldwide Developers' Conference in the summer. But little has been said about it ever since, until  a page appeared on the Apple website and they started being sent out to developers and other pros. Together it is intended to be far and away the most powerful computer that App

A huge object that flew past Earth  might be an alien spacecraft, scientists have said. Scientists had originally thought that the cigar-shaped object was a very strange passing asteroid. But a number of things have led scientists engaged in the search for alien life to wonder whether it might actually be an "artifact" from an alien civilisation. Researchers involved in the Seti – Search for Extra-Terrestrial Intelligence – project are now preparing to point a powerful telescope at the bizarre object and find where it came from. The mysterious object, which has been named Oumuamua, is our first visitor from another part of the galaxy to make it into our solar system. It flew past in October when it was spotted by astronomers from the University of Hawaii. Scientists initially presumed that it was an asteroid. But a number of strange characteristics have led them to wonder whether it might have been intentionally formed . Some researchers have suggested
