An airport in Norway has been cleared of snow by completely autonomous snowploughs, and it could help reduce airport delays.

The technology uses 4G communications and GPS to allow retrofitted machines to navigate around runways. The 5.5 metre wide vehicles are capable of clearing 357,500 square metres an hour, and can work in formation with several other snowploughs at once, further increasing their efficiency.

This machine can mow around signposts. It's called the LSM 740, and it's made by Dücker.

It uses two mower disks, each controlled by a sensor. It automatically turns the mower when near a post in order to cut around it without damaging it. This makes mowing roadsides much easier.

Dücker also makes a range of flail mowers, which use a large spinning drum to cover a wide area. The mowers are all mounted onto a hydraulic arm, which can hold a range of attachments.

A home like this can be built in less than 24 hours at a cost of only $4,000. The secret? 3D printing. And they could help families living in poverty and unsafe conditions. New Story, a housing charity organization, and ICON, a construction tech company, have partnered together. Their goal is to end global homelessness. 

Alexandria Lafci: So having strong, sturdy walls, having a door that we can close at night — it's something that we take for granted. Being able to lock our door and be safe. For many of these families, for years, sometimes even a lifetime, they don't have that opportunity to have a safe shelter. So when they move into a New Story community, when they move into a safe home, families lives are transformed.

An entire community of these 3D printed homes will be constructed in El Salvador. The ultimate goal is to get costs down to $4,000 per house with a build time of fewer than 24 hours. 

This prototype house was built in Austin, TX. The home measures 650 square feet. Mortar was printed layer by layer. Human workers installed windows, doors, plumbing, and electrical systems. Here's what's inside: A living room. Small office space. One bedroom. One bathroom. ICON staff will use the home as an office to test the durability.

Evan Loomis: Our first product is a 3D printer that can print a house in 24 hours for half the cost. Phase one for News Story and for ICON is a proof of concept house and the good news is we've done it. We printed the first home in the United States that's going to be permitted and for us, this is just the beginning. The real kind of home run for us is to be able to do what we've done here in Austin, Texas in the developing world and we're doing that in what we call phase two which is in El Salvador. We are going to be printing an entire village for people that don't have homes.

Whenever you enter a restaurant, you're putting your health in someone else's hands. Thousands of people get sick from food poisoning each year. But thankfully chefs can take steps to minimize the risk. One of those ways? Boiling lobsters alive. Turns out, those unusual tanks of live lobsters in restaurants isn't just there so you can have a plate of fresh lobster.

Following is a transcript of the video:

If you walked into a kitchen and saw a pig cooked alive on the stove, you’d probably be horrified and lose your appetite. Yet, this is how millions of lobsters meet their fate in American kitchens each year. Some people even relish choosing which lobster’s time is up at restaurants or markets across the country. But is a lobster really any different from other animals we eat? Why do we boil lobsters alive? And why do places even sell live lobsters? Turns out, this seemingly barbaric way of cooking lobsters could actually save your life.

Humans were boiling lobsters alive thousands of years ago. The first recorded case came from recipes attributed to the famous Roman Cook Caelius Apicius in the first century. American chefs later adopted the process by 1880, when they discovered that the dish looks and tastes better when the animal is boiled alive. It wasn’t until later that we realized this also reduces the risk of severe food poisoning. That’s all because of these little guys. They’re a type of Vibrio bacteria. And they thrive on the decaying flesh of lobsters and other shellfish. If a lobster dies, you only have a few hours before these bacteria show up to the party. And once they’re in, it’s nearly impossible to get rid of them. Even cooking the lobster meat won’t kill all of the bacteria. So it’s safer to just keep the animal alive right up until you serve it.

If Vibrio bacteria end up in your system, it’s not pretty. You can experience abdominal cramping, nausea, vomiting, fever, chills, and sometimes even death. Luckily, there’s a pretty good way to tell if that meat has gone bad. Just smell it. You can easily smell the ammonia that is released when the body starts to decompose.

So boiling lobsters alive save us from a world of pain, but what about the lobsters? For starters, lobsters don't scream when you boil them. In fact, they lack lungs and don’t even have the proper biological equipment to form a scream. What you hear is air and steam escaping from the shells of their simmering suppers. In any case - we don't do this to chickens or pigs because it’s pretty obvious that they can feel pain. For lobsters, it’s less clear if their primitive nervous systems and brains even know what pain is. When a lobster thrashes around in the pot does that mean it’s in agony? Or is it simply a reflex response to the boiling water, but not a conscious action? No one really knows, so more research is needed.

Regardless, some say this uncertainty is exactly why we should think twice.

Anil Seth: With lobsters, we just don't know if they can feel pain. There’s a thing in ethics that we call the Precautionary Principle, when not knowing we should err on the side of caution. If there is the potential for something to have the ability to suffer, we should treat that possibility very seriously. So boiling lobsters, not a very good idea.

New Zealand and Switzerland certainly agree. They’ve gone so far as to make it illegal to boil lobsters alive. Should America follow suit?

Fake news has been a problem swamping the internet. Now there is a way to make fake videos with nothing more than your laptop. FakeApp can be used to make fake videos of people using images or other videos of them. Several social media platforms are filled with these deepfakes. While the technology still needs works, it's been used to put celebrities into pornographic films. What would happen if world leaders became digital puppets?

Following is the transcript of the video:

Steve Kovach: You've probably seen this Snapchat filter before. It's called Face Swap. It's an augmented reality feature that takes someone else's face and puts it on your own. But it turns out this fun technology is becoming easy for anyone to use. And not just in Snapchat.

This is called a deepfake. They're shockingly easy to make. And for the most part, people use them to make goofy videos. But there's a darker side to this. It used to be you had to be a world-class film editor to get this effect. But now anyone can do it with just a simple app. FakeApp is a free PC program based on Google's opensourced machine learning technology. Since it's opensourced, anyone can have access to this technology to make fake videos. Think of it as an advanced version of their Snapchat lenses. You feed the program hundreds or thousands of images, and it spits out a fake video.

Deepfakes have already started spreading through many online communities. Most are harmless, but they have crept into the darker parts of the internet too. Of course, a lot of these are silly and goofy. This deepfake shows Nicholas Cage as Lois Lane in a Superman movie. But some have used it for malicious reasons. Like taking celebrity images and putting them in pornographic videos. Gal Gadot and Taylor Swift were some of the many victims of this trend. Twitter, Reddit, and some adult sites have already promised to ban deepfake videos. But the problem doesn't end there. Some are worried that as technology gets better, it can be used to spread hoaxes, conspiracy theories, and fake news online.

Senator Mark Warner: The next wave of technology will be able to have your image with words coming out of your mouth that may not be said, or your face put on somebody else's body in terms of next wave of technology.

Kovach: Could you imagine making a digital puppet out of Barack Obama, or Donald Trump, or Vladimir Putin? Researchers at Stanford University already did this. Imagine someone making a video like that to make a world leader declare war on another country. It's a scary proposition. In the digital age, we've even seen governments use tools like Photoshop to spread propaganda, and with deepfake videos, it's going to take the problem to a whole new level. Social networks are designed to promote content with shock value and shareability. Companies like Facebook, Google, and Twitter have done little to prove that they can handle fake news.

Anchor: Facebook is the most important mechanism facilitating the spread of fake news.

Anchor: Facebook just allows us to quantify that more. How real do you think the fake news problem is?

Guest:  It's a real problem.

Anchor: Facebook CEO Mark Zuckerberg today finally speaking out. Admitting mistakes and vowing to correct them.

Kovach: But if they already have a problem weeding out fake news articles, how are they going to handle fake news videos? Congress hasn't shown that it's willing to regulate the tech industry, and it's unlikely someone else will come in and fix it before the problem gets worse.

The best advice to avoid deepfake hoaxes is the same advice to avoid all fake news and conspiracy theories. Stick to trusted news sources, that you know deliver reliable information. For now, deepfake technology isn't that great. But we should focus on it today, because tomorrow this could look pretty real.

President Trump: Eight billion. Net worth, not assests, not liabili--, a net worth.

Meet SoFi, the little robotic fish that could help change the way we study the ocean. Created by researchers at MIT, SoFi is capable of swimming alongside real fish without any disturbance, this is due to the robots appearance and movements mimicking that of marine life.

SoFi is powered by a smartphone battery and controlled remotely - using ultrasonic signals to communicate. A hydraulic pump moves its flexible, soft silicone tail, allowing it to move nimbly in the water. 

The robot is still in development, and the team plan to improve its swim speed and design, eventually including technology to allow SoFi to swim autonomously.

Following is the transcript of the video:

So, I have the top three smartphones you can buy right now. Got the Google Pixel 2 XL, which has an amazing camera. Got the Galaxy S9+ with a dual lens camera. And got the iPhone X or iPhone 10, which has also a dual lens camera.

Let's start off with the office environment at the BI offices. This is mixed lighting there's some of the artificial lights up top, there's some light coming through the windows, so this is a good test for a smartphone camera. And I gotta say in this one, it was the Pixel 2 XL that really won out. The Pixel just offered the best color, it was the most accurate color. It's what I see when I look at it through my own eyes.

Now for a look at how each phone handles colors in an indoor lighting environment. So, taking a look at these flowers with indoor lighting, it's kinda warm, yellow lighting. Colors on the S9 photo kinda looks washed-out. The Pixel and the iPhone did really well here, with the iPhone winning out for colors in indoor lighting.

Alright, let's take a step outside to check out how these photos do with HDR, High Dynamic Range. That's basically how a camera handles super bright spots when there's also like a darker spot in the photo as well. So here we have these tall Manhattan buildings, and then just the super bright sky in the middle with the clouds. So that's perfect test for HDR. And here I'm gonna call the Pixel on this one. Again, the HDR on the Pixel kinda won out on the others. That's not to say that the others looked bad. The iPhone looks good also, it's just a little yellow.

So, here's a really tough one for smartphone cameras. This is a dark, reflective surface. That means that the camera has to deal with this dark surface, but also these super bright spots on this dark surface that are reflecting off it. So that's really tough for smartphone cameras, and honestly, a lot of cameras as well. But here, I gotta say, the iPhone won out here for sure. And actually, the Pixel just totally blew this one.

Next up, we have the Statue of Liberty taken from Lower Manhattan, and here I gotta say it's pretty clear to me the iPhone or the Pixel did the best. The S9 again did this thing where it just homogenizes the whole photo. It kinda just looks grayish. So, I couldn't leave it there, especially with the Statue of Liberty being so far away. This was a perfect test for the 2X zoom lens on the iPhone X, or 10, and the Galaxy S9+. The Pixel is not part of this test here, because it doesn't have a zoom lens. I think the iPhone looks better here. It just has this sort of deeper contrast, which we've seen in a lot of the previous photos. S9 again kinda does it's thing, where it's just sort of like makes things a little too bright, washes out some colors.

Now we go into Galaxy S9 territory, Samsung territory: low lights. So I took this photo here of this painting at home. The Galaxy S9 does incredibly here. I am just amazed and still shocked how good Samsung's cameras are at low light situations.

I guess it's time to call it. Which one is the best? This is a tough one, guys. I gotta say, I think the Pixel 2 is still the best smartphone camera you can find right now. That's not to say that the S9 and the iPhone are bad, it's just the Pixel just edges them out a little bit overall, and that's what we're gonna see for the foreseeable future. We might see something with the Galaxy Note 8 in a few months time, maybe Red's special crazy camera phone will hold some surprises for us. We'll have to see. But, for the foreseeable future, and for a little under a year now, the Pixel 2 still has the best smartphone camera.

In 2002, Microsoft announced Xbox Live, an online gaming service that allows people to play video games with each other without being in the same room. Since then, it's amassed 60 million active users, and during that time, it's become a racist and toxic environment for players of color.

Following Terrence Miller's incident, Twitch responded to Polygon with the following. "Twitch has a responsibility to broadcasters and players to provide a welcoming environment. As such, we are exploring new tools and processes to increase awareness and mitigation of these issues, and will continue to take action against chatters who committed reported violations."

When asked for comment Microsoft responded with the following.“Keeping everyone safe is a priority for Xbox. Our code of conduct helps all players have a safe, secure, and enjoyable experience, and any activity that violates these terms may result in enforcement action. Content that is prohibited in Xbox Live includes negative speech (including hate speech or threats of harm) directed at people based on a number of factors, including race, ethnicity, or nationality. We also encourage our community to use the "Report" option to flag content to the Xbox Live Policy & Enforcement Team. You can learn more at  http://enforcement.xbox.com."

PlayStation did not respond to a request for comment.

If working out is good for you, then working out more can only be better for you, right? Not quite. Too many trips to the gym or cardio sessions could actually undo all of those gains you've been working towards. Worse, they might be doing damage to your heart, arteries and causing your brain to become addicted to exercise. Scary stuff!

Following is the transcript of the video:

Exercising is supposed to be good for you. It can help you stay at a healthy weight, improve your cardiovascular health, and even ward off depression. But like most things, it’s possible to over-do it. And getting too much exercise can have serious consequences for your body and brain. So, what exactly is “too much” exercising?

Well, it depends on factors like your age, health, and choice of workouts. But in general, adults should get around 5 hours a week of moderate exercise or 2-and-a-half hours of more intense activity. Or some combination of the two. That's according to the CDC. But research shows that going way above and beyond that doesn’t increase your health benefits.

One unsurprising study found that light to moderate runners had a lower risk of death than people who didn’t exercise. But, in a surprising turn, some people who ran at a faster pace for more than 3 times a week had a similar risk of dying as the non-runners. So running too much, and too intensely, seems to undo some of the health benefits gained from regular running.

Extreme endurance exercises, like ultra marathons, may also lead to heart damage, heart rhythm disorders, and enlarged arteries, in some people. Experts believe extreme endurance puts extreme demands on the cardiovascular system. One study found that repeated extreme exercises can “remodel” the heart, thickening the muscle’s walls and scarring tissue.

Another study showed that women were less likely to have a heart attack or stroke, if they were physically active at least once a week. But that risk of heart attacks and strokes shot up for women who exercised strenuously every day. So, excessive exercise doesn't provide more benefits than moderate exercise. And it could be more risky.

Women are at particular risk for what's known as the "female athlete triad" that includes: loss of menstruation, osteoporosis or bone mineral loss and eating disorders. These symptoms usually arise from a combination of overexercise and calorie restriction.

For men, intense exercise has been shown to decrease libido. Possibly due to physical fatigue and lower testosterone levels. For both men and women, overexercise raises the risk of overuse injuries, like tendinitis and stress fractures. These injuries result from repetitive trauma. Your immune system can likewise suffer.

While moderate exercise can improve your immune system, excessive exercise can actually suppress it.

There's up to a 72-hour "open window" of impaired immunity after intense exercise. This basically means viruses and bacteria might have an easier time invading and infecting the body. And athletes who overexercised also experienced more upper respiratory tract infections.

So, we know excessive exercise can wreak havoc on your body — particularly your heart, tendons, ligaments, and immune system. And for around 1 million people in the US, exercise addiction is wreaking havoc on their brains.

Symptoms of exercise addiction include withdrawal — that's when you feel anxious or exhausted when you miss a workout. Or feeling a lack of control and unable to cut down on exercise. Even when you know it's hurting you.

Now, it’s important to understand that you shouldn't just give up on exercising. The key is to get the right amount.

So, feel free to go forth and run. Just not all the time.
