Little asteroids strike the Earth's atmosphere every single day. It's the big ones we worry about, as depicted in such Hollywood extravaganzas as "Armageddon" and "Don't Look Up." "I've never been able to sit still watching any of the asteroid movies and not just want to get up and walk away," said MIT professor Richard Binzel. In addition to writing the book on asteroids, he also invented the Torino scale, a 10-point danger scale for asteroids. "All the objects we know of today reside at zero or one, which simply means they're so small that they don't matter, or that we know for sure there's no impact possibility," Binzel said. Correspondent David Pogue asked, "It sounds like asteroids wiping out humanity should not be at the top of our list of worries?" "Asteroids wiping our humanity does not keep me awake at night, unless I'm at the telescope studying them!" Binzel laughed. But there have been dangerous asteroid strikes. In 2013, a 60-foot rock from space injured 1,500 … [Read more...] about DART mission: How NASA hit the bullseye

A combined Chinese and Russian naval convoy, including a guided missile cruiser and a destroyer have been spotted close to an Alaskan island by the US Coastguard. Two other Chinese naval ships and three Russian naval vessels were sighted in the Bering Sea in a single formation 86 miles (138 km) from Kiska Island by the US Coast Guard cutter, Kimball. The Honolulu-based vessel monitored the ships before they broke formation and dispersed. A C-130 Hercules provided air support from the Coast Guard station in Kodiak. "While the formation has operated in accordance with international rules and norms, we will meet presence with presence to ensure there are no disruptions to US interests in the maritime environment around Alaska," Rear Admiral Nathan Moore, Seventeenth Coast Guard District commander, said. The Coast Guard said Operation Frontier Sentinel guidelines call for meeting "presence with presence" when strategic competitors operate in and around US waters. … [Read more...] about Chinese and Russian warships spotted off Alaskan island
In much the same way as evangelicals confront thorny issues by asking themselves: “What would Jesus do?”, so Tories have long plotted their course by considering: “What would Maggie do?” Around about now, it must surely be dawning on them that Thatcher’s assessment of how Liz Truss is managing the economy would be: not like that ! Yes, the Conservative party’s secular saint also inherited a moribund economy that was struggling with high inflation. And, yes, she cut the overall tax burden and slashed red tape in order to combat deep-set economic sclerosis and boost growth. But the Iron Lady was tactical as well as strategic about how she achieved those aims. By focussing on an abridged version that only assesses the ultimate destination while ignoring the journey she took to get there, the self-anointed heirs to Thatcher have arrived at a conclusion that is both ahistorical and reckless. The current Prime Minister and her Chancellor Kwasi Kwarteng have, in fairness to them, had … [Read more...] about The Iron Lady had strategy – Kwarteng, stupidity
By Sarah Dickins Published 9 August 2017 Share close Share page Copy link About sharing A housing development in Neath, designed with the aim of turning "homes into power stations," is as exciting as it is innovative. The Port Talbot-based Specific partnership involves Tata Steel, Swansea and Cardiff universities, firms including BASF and Pilkington, and more than 130 scientists and product developers. These particular proposals involve eight two and three-bedroom homes and apartments. The Specific innovation aims to transform how we view the role of our homes, offer a way of reducing our dependence on carbon fuels and also act as a tool to help further tackle fuel poverty in Wales. Despite a range of initiatives to reduce the cost of keeping homes warm, latest figures estimate that nearly one in four (23%) of households in Wales were still considered to be living in fuel … [Read more...] about Analysis: Could future homes actually work for us?
Russian forces in the Donetsk region town of Lyman were on Friday encircled by the Ukrainian military, overshadowing Vladimir Putin’s annexation of four Ukrainian regions . The government in Kyiv urged Russian troops to lay down their arms and surrender as long-range Ukrainian weapons made it virtually impossible to reinforce or escape the town via the last remaining safe highway. Heavy fighting was reported on the outskirts of Lyman, as separate Ukrainian forces advanced in a pincer movement designed to surround their enemy. A military setback in the town, which has served as a key logistics hub for Russia’s operations in the Donbas, would be one of Moscow’s most significant failures of the war. As Ukraine’s forces advanced on the town from three directions, the village of Yampil, directly south east, was liberated and Russia abandoned its forward defensive position in Drobysheve to the north. Military officials largely maintained operational silence, but hinted that an … [Read more...] about Encircled Russian forces urged to lay down arms in key Donetsk town
