    Matt Hancock says Covid-19 outbreak could force UK to shut down cities

    China, of course, isolated entire cities Is it conceivable under any circumstances you’d try and cut off the city in this country? Well, there’s clearly a huge economic and social downside to that, but we don’t take anything off the table at this stage because you’ve got to make sure that you have all of the tools available, if that is what’s necessary. But, you know, I want to minimise the social and economic disruption. It may be necessary and I’m not saying any of these things are decisions being taken, but there are things that we don’t rule out. It may be necessary, for instance, to close some schools.…

    The First Results from NASA’s Insight Lander! | SciShow News

    [♩INTRO] In 2021, Mars is set to receive new robotic inhabitants. But until then, we have other explorers hard at work learning what makes the Red Planet tick. Like NASA’s InSight lander! InSight touched down in November 2018, and its first results were finally released this week in two Nature journals. The results reveal a seismically active world with magnetic and atmospheric phenomena, all begging for further investigation. InSight lives in a sediment-filled crater in the Elysium Planitia region a volcanic plain a bit north of where Curiosity is. Its mission is to learn what it’s like beneath Mars’s surface. And to do that, it brought along some really cool…

    7 Ways We Know What’s Inside the Earth

    [♪ INTRO] In 2003, the journal Nature published a paper describing a rather unusual proposal. The author suggested that scientists use a nuke to crack open the Earth’s crust and then toss in a vibrating, grapefruit-sized recorder filled with scientific instruments. The whole mess would sink through molten rock and metal until it reached the Earth’s core a couple of weeks later. Now, this article was not actually a supervillain announcing their dastardly plans. It was more of a tongue-in-cheek thing. The goal was to illustrate just how hard it is to study the inside of the Earth. I mean, we can see billions of light-years through space. But when…

    How Far is Too Far? | The Age of A.I.

    Welcome to YouTube Original Stages, once home to Howard Hughes’s Spruce Goose assembly hangar, and home to much of the firstIron Man,filmed 12 years ago. Many happy memories here. And speaking of taking a look back… Technology. It’s advancing faster and taking less time to be widely adopted than ever before, like as in it took roughly 10,000 years to go from writing to printing press, but only about 500 more to get to email. Now it seems we’re at the dawn of a new age, the age of A.I… Artificial Intelligence. Please define. [automated voice speaking] Uh-huh, okay. There you have it. What does it mean? I don’t know.…

    Eva Kor: The Holocaust survivor who forgave the Nazis | BBC Ideas

    One day, in 1944, my family and I were arrested. Packed into cattle trains with no food or water. We were taken to Poland and left on the selection platform in Auschwitz. A Nazi guard spotted me and my identical twin sister Miriam clinging to my mother. He tore us from my mother’s arms and led us away. I remember looking back at my mother. I did not know at that time, but I would never see her again. On the filthy floor, there were scattered corpses of three little girls. Their bodies were naked and their eyes were wide open. It was a horrifying look. I had never seen…

    ‘It’s nice to meet you’: Greta Thunberg and David Attenborough speak over Skype

    It’s very nice to meet you. It’s an honour to meet you. I’m very flattered that you should say that. Thank you very much. David, what would you say to Greta about her work on climate and what you think she’s achieved? Oh, she’s achieved things that many of us who’ve been working on it for 20 odd years have failed to achieve. That is, you have aroused the world. I’m very grateful to you. But we all are, you know. When I was a young girl, documentaries about the natural world and what was happening, what was going on, that was what made me decide to do something about…

    The True Science of Parallel Universes

    Everyone loves the idea of parallel universes – maybe it’s the appeal of an ideal world where you have second chances and things turn out differently – an alternate reality where you do get into Hogwarts and the Star Wars prequels aren’t made and you finally plug in your asymmetric computer cord correctly on the first try… but is there really a place in science for such wistful speculation? I mean, if “the universe” is everything that there is, you can’t have two versions of it, right? Otherwise the pair would really be everything and what you started off calling the universe, wasn’t. The problem here is terminology: physicists speaking…

    Viruses (Updated)

    Subtitles on! Click CC at bottom right to turn off. You can find us on Twitter (@AmoebaSisters) and Facebook! Chances are, in your life, you’ve had the common cold before. It can cause sneezing and coughing and just makes you feel awful. The worst thing about the common cold is that you can take medications to help with the symptoms, but you really can’t treat the actual cold with antibiotics like you would a strep throat infection or an infected tooth. Why? Well let’s talk about what causes it: a virus. The common cold is caused by a virus. And while all living things are made of 1 or more…
