China, Alzheimer's Disease, Alzheimers discussed on Exploration



Every can exploration we discussed the fascinating world of science and its impact on society and today leading our forgiveness summarize, well, the big stories of two thousand eighteen what were the big stories in science and technology that will affect your life and the lives of your loved ones as well. As the future of humanity itself. We'll we'll talk about a number of topics today. First of all leading off the number one story is climate change the United Nations released a devastating report backed by ninety scientists and six thousand few reviews stating that watch out in the coming decades. Temperatures could rise one and a half degrees, which could set off a chain reaction of negative in Navarre mental. Effects? So we'll talk about that as the lead story for two thousand eighteen and then we're gonna talk about outer space. Yes, the Mars inside probe landed successfully on the surface of Mars, and it's going to begin a series of experiments to determine the internal structure of the red planet. And then the question is well is there water liquid water on the red planet? Well, the Italian space agency says yes using ground penetrating radar. They were able to find a gigantic liquid water lake underneath the polar ice caps. And then the Japanese sent a space probe passed an asteroid, which then brings to the fore the question of whether or not it's possible to mind, the asteroid belt, some people think there's a gold mine out there and with our ability to reach out and actually landed on asteroids, then raises the possibility of one day Lhasa. A wing an asteroid bringing it back down to earth and harvesting the platinum based at rare earth elements of an asteroid which in principle could re billions of dollars in process prophets. And then of course, the space force is dominating the news. We already have the coastguard the marines. We have the army the navy and now a space force. Well, the Trump administration is going all out to convince the American people that we need space for us. But what are the pros and cons of one day? If we begin the process of militarising outer space, and we'll talk about the outer space treaty of nineteen sixty seven does it need to be revised. And then leaving outerspace. Will summarize the top news about inner space. The leading story today concerns genetic engineering experiments done in China some of them perhaps unearth rise creating a tremendous amount of crunch. The crisper techniques which allows you to to cut and paste jeans almost like using a pair of scissors. Allow scientists to begin the process of genetically engineering embryos. And so there was the announcement in China that yes, human embryos, were in fact, genetically engineered to make them less susceptible to HIV, and is creating quite a bit of controversy. And also the Chinese announced that they successfully cloned a monkey for the first time in history. You know for decades. It seem scientists said that well, we've never been able to clone a primate we've been able to clone farm animals, we can clone household pets, but primates is simply too difficult. Well, the Chinese did it they've cloned a monkey the first primate ever to be cloned. And then the question is well are humans next and then talking about DNA scientists found evidence of early humans ninety thousand years ago inside Syria, which were inbred that is able to cross between two species Neanderthal and the Denisovans, and it's sort of like Lord of the rings member that movie Lord of the rings where we have elves and orcs, and humans we have this zoo. This imagine we have this menagerie of human species, but who are different and disliked the Lord of the rings, some people. I think that today as we go back into the past with DNA techniques. Today's technology allows us to recreate the family tree of humans, and we find that there are many more branches than we thought and some of these branches well interbred with each other ninety thousand years ago, there was a female that was a byproduct of the Nisa then and and the NFL match, and so it leaves went to believe that well, perhaps our family tree is a little bit more inbred than we originally thought. And then remember that movie Jurassic Park a lot of scientists pooh-poohed saying that come on give me a break. I mean, amber that in cases lifeforms preserve over sixty five million years come on give me a break. Well, here's a discovery that was announced snake embryos encased in amber were tested, and they were found to be a hundred and five million. Nine years old. Let me repeat that again. Snake embryos encased in amber were found to be one hundred and five million years old much older, then when the dinosaurs died out, and then the question is will one day, perhaps we might find dinosaur DNA in case in amber. Well, we'll have to wait and see about that one. Also on the medical front Alzheimer's in the news. It's almost like monotonous every year on exploration. We say that we have not made any progress at all at all every verse the horrible effects of Alzheimer's disease, perhaps some of your relatives died of Alzheimers, and you know, the anguish that we face my mother died of Alzheimer's disease. And I've seen firsthand with the ravages of this is these could be could it robs you of your memories and your identity, and who you are. For the.
