  • Yeah.

  • After a thorough analysis of weekdays compiled over decades of experience, our independent study has concluded that Fridays are awesome.

  • I'm Carla Zeus.

  • We're happy to have you watching this Friday, October 16th.

  • Like several nations in Europe we told you about earlier this week, many parts of the United States are seeing an increase in coronavirus cases.

  • It's not spreading evenly.

  • As you can see on this map, the recorded number of new cases is increasing in 35 states.

  • It's holding steady in 12 states and dropping in three.

  • In the coming days, the Nation of India is expected to surpass America in total covert infections.

  • The Asian countries cases are rising and its population is four times that of the U.

  • S.

  • But at this point, America has seen more positive tests than any other country.

  • It's recorded 7.9 million diagnoses since record keeping began early this year, and more than 217,000 deaths have been blamed on the disease in America.

  • When you look at these numbers, the death rate may appear higher than it really is.

  • The reason being that as many as 40% of people who catch the virus have no symptoms, and many of them may not get tested.

  • There are also people who do have symptoms but think it's just a cold and don't get tested.

  • Based on statistics that came out this summer, more than 99% of people who catch coronavirus survive it, though it is more deadly than the flu.

  • Some American businesses and communities have strict laws in place, limiting public gatherings and requiring masks.

  • In others, people can be seen in crowded areas without masks getting back to business as usual.

  • So the restrictions and the reactions to the disease are vastly different from place to place.

  • But health officials say the threat of spreading the virus goes up as fall temperatures come down.

  • Why do we expect Kobe 19 infections to increase in winter months?

  • There are three major reasons.

  • First, the virus that causes Kobe 19 is a coronavirus, and other coronavirus is spread mawr in winter months.

  • That's the seasonal variation we see for the common cold and for other respiratory viruses.

  • So we expect to see the same pattern with this novel coronavirus, too.

  • Second, in winter months, the air is less humid particles that carry the virus can linger in the air for longer.

  • Also, our nasal membranes are drier and more vulnerable to infection.

  • Third, as the weather gets colder, people will spend more time indoors.

  • We know that being outdoors versus indoors can reduce the risk of transmission for Kobe 19 by 18 to 19 times.

  • That's because the particles that carry the virus get diffused by circulating air.

  • When people are gathered indoors in tight spaces without good ventilation, that increases the likelihood of spread.

  • All of this is why we need to stay extra vigilant in the winter months.

  • If you're seeing friends and extended family, stay outdoors as much as you can.

  • If you need to be indoors, keep the windows open.

  • Check your ventilation and keep the air circulating.

  • Make sure everyone has a mask on if you're outdoors and cannot maintain a 6 ft distance or any time you're indoors with people who are not in your immediate household.

  • Mm hmm.

  • Winter predictions are next.

  • If you were to draw a horizontal line through the center of the United States, relatively warm and dry conditions are expected south of that line in the months ahead.

  • Warmer temperatures are also expected in the U.

  • S Northeast.

  • This prediction is, according to the National Oceanic and Atmospheric Administration, or no, uh, and it's making that forecast based on something called La Nina.

  • This is a natural cooling of ocean surface temperatures in the Pacific and CNN 10 Contributor Tyler Mauldin explains how it forms forecasters at the Climate Prediction Center.

  • Carl expect La Nina conditions to have a major impact on our winter weather here in the US This year's La Nina could be on the stronger side, too.

  • A La Nina watches issued when a La Nina could soon form.

  • Our watch, however, was recently upgraded to a La Nina advisory, meaning it's here now and expected to continue.

  • There's an approximately 85% chance this Latina could continue right through the months of December, January and February.

  • I would say those are pretty good odds, wouldn't you?

  • So let's talk about what a la Nina is and how it impacts the world's weather.

  • Let's start in the Pacific Ocean.

  • This is where the action happens during a la Nina.

  • The trade winds, which blow from east to west, get a lot stronger.

  • This effects both the ocean and the atmosphere in the ocean.

  • Warm waters get pushed to the West Pacific due to the more intense wind, allowing cool water to bubble up to the surface of the east central Pacific.

  • In the air, the Walker circulation gets stronger, which is the circulation of air rising over the warm waters and sinking back down over those cooler waters.

  • The jet stream is reshaped as a result, changing our weather patterns.

  • It's impacts are felt far and wide to not just in the U.

  • S.

  • But around the world is to blame this year form or hurricanes in the Atlantic flooding in Australia, you name it 12th trivia.

  • Which of these words comes from a Latin term meaning track or rut?

  • Orbit, path, circulate or route?

  • The answer here is orbit, which usually follows a curved track around something in space.

  • In addition to millions of pieces of space junk like used rocket stages, parts of spacecraft and old broken satellites, there are roughly 3000 working satellites orbiting the Earth, and Mawr are about to join them is part of a single mission to give more people access to broadband Internet.

  • It's called StarLink.

  • It's being launched by the spaceflight company Space X, and it could add between 12,000 and 30,000 satellites.

  • Toe low Earth orbit.

  • Here's CNN 10 Contributor.

  • Chris James, Chris Hey Carl.

  • On the clearest of nights I love looking up into the sky to see if I can spot a satellite or space objects making its way across the dark horizon.

  • But experts are raising the red flag about a growing problem that could change the future of space is we know it.

  • The issue space is getting too crowded.

  • For decades, researchers have been worried that growing congestion in space could have devastating consequences.

  • This theory is known as Kessler syndrome, which says that if space traffic becomes too dense, one single collision between two objects could set off a catastrophic domino effect that would essentially turn the space around Earth into an extraterrestrial wasteland.

  • By the way, this was the main plot line in that 2013 film gravity.

  • Robert Beck, the CEO of a launch startup company called Rocket Lab, says that his company is having a very difficult time finding clear paths for rockets tow.

  • Launch new satellites due to the sheer number of objects in space right now, especially considering Space X is rapidly growing.

  • StarLink Constellation Space X has said that they are determined to being responsible stewards of outer space, and the company has equipped it's starling satellites with the ability to automatically get out of the way just in case there are oncoming objects.

  • And once operational, the Space six system could make Internet access available to the billions of people around the world who don't have it.

  • As exciting as that prospect sounds, the odds of avoiding disaster Onley become slimmer with each new satellite launch, according to one expert who says that he's optimistic that we can avoid Kessler syndrome.

  • So long is thes.

  • Companies agreed to abide by certain rules and norms of behavior.

  • Back to you, Carl.

  • One word squid by This is a project at the University of California, San Diego.

  • It's a soft robot that can push itself through the water.

  • It can also carry a camera to keep tabs on what's happening under the waves.

  • Soft robots can be less damaging to marine life than other robots.

  • And while squid Bottas faster than other soft robots, its speed tops out at about half a mile per hour.

  • Riel squids can scored along at 24 MPH.

  • Plus it probably takes an awful lot of squid.

  • I mean quid to take a shot with squid body.

  • That is, unless you think a special deal.

  • I mean, paying full price is for suckers.

  • Now, before you invertebrate me, I'm gonna go ahead and squid while I'm ahead.

  • That's enough squid ing around and we got a squid datil.

  • Anyway, shout out to Chapel School in Sao Paulo, Brazil.

  • We received your request on our YouTube channel.

  • I'm Carl.

  • Jesus.

  • Have a great weekend from all of us here at CNN.

  • Mhm.

  • Okay, yeah.

Yeah.
