A team of researchers may have just stumbled upon the cure for diabetes by fusing mice with stem cells. The results are extremely promising.

For those that don't know much about diabetes, here's a quick summary of the disease. People who have diabetes find it hard for their bodies to produce a reasonable amount of insulin. The current treatment for this is regular exercise, strict diet, and insulin shots. In the human body, the pancreas produces insulin, but in the case of a diabetic, their pancreas does not produce enough. This means patients have to monitor their blood sugar levels and directly inject insulin into their bloodstream.

In the new study, researchers led by Jeffrey Millman from Washington University in St. Louis, Missouri, found that using pluripotent stem cells (iPS cells), which are stem cells that can be manipulated into becoming almost any cell in the body, they can cure diabetes. Unfortunately, when using these stem cells, not all of them convert into the desired cell, in this case, insulin-producing cells. This means that some random cells enter the bloodstream along with converted insulin cells.

NASA loves jamming probes into holes to examine things, and in this case, Mars was lucky enough to be a candidate.

While you might think this is an over-exaggeration, that's hardly the case. NASA sent it's InSight robot to Mars to examine several aspects of the strange red planet, and since it's been on Mars, it has achieved quite a lot. InSight was able to measure and record some strange martian sounds, that were believed to be Marsquakes and martian wind. Now, NASA has published some of the latest findings from InSight.

InSight is stationed on the Mars surface, and it uses its seismometer instrument that's stuck in a hole to record ground motions. When NASA first detected the Marsquakes, they weren't able to accurately distinguish the sound of quakes in comparison to other potential sounds. Since then, NASA has gotten much better at this and is now able to separate the sound of the wind from the quakes.

It looks like coronavirus could be causing a bigger stir throughout the world than previously thought, with Mobile World Congress (MWC) canceled over it -- people pulling out left, right, and center of the Game Developers Conference (GDC) and Computex 2020 in Taiwan now possibly in question.

How could it get worse? Seeign the Tokyo 2020 Olympics canceled. This is now a possibility, with International Olympic Committee member Dick Pound talking with the Associated Press recently, where he said that the committee will be making a final decision throughout discussions with the World Health Organization (WHO).

Pound said: "All indications are at this stage that it will be business as usual. So keep focused on your sport and be sure that the IOC is not going to send you into a pandemic situation. It's a big, big, big decision and you just can't take it until you have reliable facts on which to base it. You just don't postpone something on the size and scale of the Olympics".

At the moment, 3D printing technology has an uncapped potential, and something to reinforce that fact is scientists successfully 3D printing the world's first cornea.

Researchers at Newcastle University, located in the United Kingdom, have recently published a new paper that details that they have successfully 3D printed the world's first cornea. The aim behind this research is to provide patients who are blind or are deteriorating into blindness with a replacement cornea for their eyes. At the moment, there's a huge demand for human cornea transplants, but if researchers can print them and distribute them out to patients accordingly, then those waitlists for transplants would be reduced significantly.

So how does this work? Researchers took corneal stem cells from a healthy donor and added the samples to alginate and collagen. The result of this mixture was what is called "bio-ink". From this stage, scientists were able to perfectly form the ink into the cornea shape using a 3D bio-printer. Of course, with most bleeding-edge level technology, it will be several years before the printed corneas are issued out to patients, as researchers still need to perform numerous levels of testing to ensure safety. Regardless of the wait time for the corneas, it still proves that this idea is completely feasible.

A man that was a massive advocate for the Flat Earth Theory has tragically died in his homemade rocket that crashed landed into the desert.

The man was "Mad" Mike Hughes, who built homemade rockets with limited funding for a Science Channel series called "Homemade Astronauts". The series' aim was to document the adventures of rookie rocket designers. Hughes' goal for his homemade rocket was to prove to the world that Earth was in fact a flat disc by viewing it from space himself. This also wasn't Hughes' first attempt at reaching space, back in 2014 the homemade astronaut reached a height of 1,374ft, then in 2018 he reached 1,875ft.

The rocket was steam powered and during his launch in 2020 the chute detached, causing him to collide with the Barstow, Californian desert at an extremely high velocity. The rocket was also not tested correctly as Hughes didn't have the funding that NASA or SpaceX has, instead he had $18,000 sourced from fellow flat Earthers and extreme levels of confidence in his creation. Flat Earth advocates have been beating the drum that the Earth is disc shaped since we realised that the Earth was spherical, much like all the other planets/exoplanets.

The United Kingdom decided to release a large portion of UFO related documents to the public, under the Freedom of Information act. This decision has no doubt sparked interest of UFO's globally, but what do Americans think?

Market research firm, Piplsay has posted a new article regarding the mystery behind UFO's and whether or not Americans would like to see the disclosure happen in their country as well. According to the paper, which polled 30,741 Americans, around 61% of those who were polled want the American government to follow in the footsteps of the UK government and disclose what they have to the public. Out of those 30,000+ people, 27% of them didn't want to the files disclosed, and 12% said they don't care what happens.

The paper also says that around 58% of those that were polled think that the American government is investigating alien life. 25% of the Americans believe that the US government isn't investigating alien life and 17% aren't sure what they are doing. Around 27% of Americans think that UFO sightings are real, while 34% of them are a bit unsure about what their answer is. Piplsay also polled 4,161 people in the UK, and it was found that 60% of those people are excited about the disclosure of the "X-Files", versus the 28% of those people believing the disclosure will cause "madness".

SpaceX is wanting to raise another $250 million in new funding according to CNBC, with the new cash seeing Elon Musk's space-venturing company worth around $36 billion.

The $36 billion valuation is a $2.5 billion increase in the last time the reported valuation came in, with Elon Musk seeing SpaceX injected with around $1.33 billion across 2019 from 3 different rounds of fundraising. SpaceX has rounded up $3 billion or so in funding over the years, but it's no wonder as it continues to push the boundaries of technology and dominate beyond our pale blue dot.

NASA awarded SpaceX over $3.1 billion to develop the Crew Dragon capsule that the company built to take astronauts to the International Space Station, with Musk saying SpaceX has spent "hundreds of millions of dollars" of its own funds to develop Crew Dragon.

One of the biggest problems we all face on Earth is if a large asteroid decides to line up Earth. It's an even bigger problem if that asteroid is so large that it falls into the category of "planet-killing".

So, in the event of one of those asteroids making its way over to Earth, how do we defend ourselves as a planet? MIT researchers have announced a battle plan for dealing with a "planet-killing" asteroid being on a collision course with Earth. According to the new paper, there are three options for missions that could be prepared in reasonably short notice. The first is "type 0", and is when a single, heavy spacecraft is fired at the asteroid using all information gathered from Earth to knock it off course.

The second is "type 1" mission, and that is when a scout craft is launched first to examine the asteroid. With the data gathered from the scout craft, humans back on Earth would be able to launch an impactor craft more accurately. The third option is "type 2" mission, which is when an impactor craft is launched at the same time as the scout craft. The scout craft then examines the asteroid after the initial impact, then relays data back for a second impactor that should finish the asteroid off.

It was only a few weeks ago that astronomers announced that they received what is called Fast Radio Bursts from deep space. Now, a Harvard scientist and astronomer have said that it could be aliens who are sending the signals.

If you don't know what Fast Radio Bursts (FRB) is, here's a quick summary of what has happened so far. In January 2020, astronomers picked up FRB's from deep space, and while this is originally a rare finding, these signals are usually traced back to a cosmic event such as stars colliding. What puzzled astronomers were that these new FRB's were arriving in a regular pattern.

The pattern was that the FRB goes through a four-day cycle of regular activity almost every hour, then after those four days, it would go dormant for 12 days. The researchers also said that the source of the FRB would sometimes skip it's four-day activity period and only let out a single burst. This discovery broke all explanations towards for what the source of the FRB could be.

A study has shined a new light on how traditional Western-style fast-food diets can lead to memory and brain deficiencies.

The new study was published in the Royal Society Open Science and has examined the effects of high-fat, high-sugar, and processed foods and how they affect cognitive ability. Researchers took 110 participants aged 20-33, who were generally healthy and split them into two groups. The first ate their normal healthy diets for a week, and the other was assigned a calorie-heavy Western-style diet filled with fast-foods.

At the start and end of the week, both groups were asked to rate how much they like sugary foods while eating breakfast. The participants were also asked to rate how much they wanted to continue eating them and were also given a memory test. Richard Stevenson, study co-author and psychology professor Macquarie University in Sydney, found that "After a week on a Western-style diet, palatable food such as snacks and chocolate becomes more desirable when you are full. This will make it harder to resist, leading you to eat more, which in turn generates more damage to the hippocampus and a vicious cycle of overeating."

Elon Musk's SpaceX is checking off milestones as it moves towards making commercial space travel a real thing. Now, we are hearing about when SpaceX will be taking its first tourists.

TheNextWeb has reported that SpaceX will begin to send tourists to orbit as soon as 2021, but the costs it won't be like a international flight -- they will be much higher than that. Space Adventures is the company that will be handling the bookings for SpaceX's orbital experience, and they also handled the brokering deal of tourists going into orbit throughout 2001 and 2009.

According to Quartz, the last space tourism flight by Cirque du Soleil founder Guy Laliberte cost a whopping $30 million. Space Adventures expects that SpaceX will be taking four passengers on their first flight to space "late 2021 and mid-2022", but that won't happen until the Crew Dragon Capsule completes its first manned flight in just a couple of months. Once that is complete, SpaceX has set the runway for tourists entering space.

Back in late April 1986, a nuclear accident happened that shook the planet. This disaster was none other than Chernobyl, and the nuclear fallout was devastating.

Since the Chernobyl nuclear explosion, the radioactive site has become more of a real-life research site for scientists. Researchers have since sent in several robots to examine the site and how the nuclear fallout has affected both plant and animal life. In 1991, a team found that black-spotted fungi were growing on the walls of one of the nuclear reactors. The team also found that this fungi was slowly breaking down the radioactive graphite from the core, and was growing more strongly towards the center of the zone.

In 2007 a follow-up study was conducted by researchers at the University of Saskatchewan, and found that certain types of fungi were "attracted" to radiation and actually grew more rapidly in radioactive conditions. The three fungi species were Cladosporium sphaerospermum, Cryptococcus neoformans, and Wangiella dermatitidis. These species of fungi and five others were then sent to the International Space Station in 2016 to be exposed to further radiation.

Alright, so I need to do this -- it has gone to the top of my bucket list instantly. Jetman Dubai has unleashed a new video that shows pilot Vince Reffet flying through the sky in a jet-powered carbon-fiber suit like a real-life Superman, or Iron Man, depending on how you want your superheroes.

The pilot launches off the ground and flies into the air at around the 2-minute mark in the video, flying around Dubai and heading south towards Jumeirah Beach Residence. Jetman Dubai notes that Reffet in "eight seconds [Reffet] had reached 100 meters height, in 12 seconds 200m, 19 seconds 500m, and reached 1000m in 30 seconds at an average speed of 130 knots". Crazy, but oh-so-damn-awesome stuff.

Reffet has a bunch of GoPro cameras attached to the suit which gives us some utterly gorgeous footage of his flight, which is wicked-fast in the end and makes me want to do it personally... even though I'm deathly afraid of heights, it would be a once-in-a-lifetime experience, that's for sure.

NASA has announced that Rocket Lab will be the company to provide launch services to get their 55-pound satellite to the Moon's orbit.

More specifically, Rocket Lab will be taking the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE), or CubeSat to the Moon's cislunar orbit. Once it has arrived, it will learn the Moon's seven-day cislunar orbit cycle, and relay valuable information back to Earth that will allow engineers and NASA to better prepare for future missions.

The CubeSat will be aboard the Electron rocket and blast off from NASA's Wallops Flight Facility in Virginia. At the moment, the mission is targeted to launch sometime in early 2021, and the firm-fixed launch contract is valued at $9.95 million. If you are after anymore information regarding this new contract, check out the official NASA press release here.

Marques Brownlee has sat down with Microsoft founder Bill Gates to give a quick overview of Gates Annual Letter 2020.

The above video was released onto Marques Brownlee's YouTube Channel, and it's basically an overview of Gates' 2020 annual letter that was released onto his website. The letter that Gates and his wife wrote, Melinda Gates, details their 2020 plan on how they are going to tackle issues such as global health (vaccines), education, climate, and more.

Gates and his wife discuss in detail that their strategies for 2020 and how some of his endeavors for creating new solutions are 'high-risk' and might cost a lot of money, but it would be worth it if it paid off. In the video, Gates talks in detail about bringing the 'green premium' (the extra cost in using green alternatives) of using environmentally friendly alternatives down to zero. If you are interested in what Gates' plan is, check out the above video or the annual letter here.

This is not a joke. A group of people are attempting to sell DNA samples of the global elites, and some of the names on the list will surprise you.

I wouldn't blame you if you thought this was a joke, because I certainly did until I read the website as well as the press release. According to the website, a mysterious group that has called themselves the Earnest Project is scheduling in an auction for items that were collected during the 2018 World Economic Forum at Davos. Some of the items are as follows: glassware, cigarettes, paper cups, cutlery, jars, serviettes, hair, and more.

The press release by Earnest Project says, "Third-party verification of EARNE$ T's attendance at Davos will be made available prior to the auction date. Past Davos attendees may also be consulted to verify the plausibility of the collection-action. Many attendees may recall enjoying a muesli parfait (lot #402) in the Central Lounge for instance. Page 10 of The Collection Catalogue provides further details on collection sites."

Astronomers around the world have their observational eyes fixed on the red giant Betelgeuse, as they are patiently awaiting any signs of detonation.

If this is the first time you are hearing about Betelgeuse, don't stress we aren't in any immediate danger. Betelgeuse is located around 650 light years away, and astronomers have estimated that due to it's dimming cycles the star could explode anytime within the next 100,000 years. What's concerning, and what has caused astronomers from around the world to focus their attention on Betelgeuse is the fact that the red giant seems to be dimming at an unprecedented rate.

Betelgeuse is currently sitting at around 35% of it's normal brightness, which has moved it from it's normal position of the 11th brightest star in the sky to the 24th bright star in the sky. These variations in Betelgeuse's brightness are normal, as the internal temperatures inside the star rises and falls. What isn't normal is how rapidly it's doing it. Astronomers used the European Southern Observatory's Very Large Telescope instrument called 'SPHERE', SPHERE allows astronomers to capture polarized infrared light of objects.

League of Legends is one of the biggest games ever created with a player base of over 100 million players. So how much carbon are those players generating?

In a new study, it has been estimated that League of Legends' 115 million players throughout 2019 resulted in around 3,139,385 tonnes of CO2 emissions, based on the average player game time. This amount of output of CO2 is estimated to be around the same as charging 400,372,745,210 smartphones or driving 7,790,037,221 miles.

Both gaming companies and consoles manufacturers are working towards minimizing their carbon footprint, and with study's such as these and others coming out estimating how much carbon they are producing, they are really putting them in a not-so-good spotlight. I don't know if a few studies will push big game companies such as Riot Games to implement a carbon reduction strategy, but it's a start, I suppose.

At the moment, SpaceX is gearing up for the first crewed flight to the International Space Station with their Dragon spacecraft.

According to recent reports, paperwork is the main problem before SpaceX is given the green light to take astronauts Bob Behnken and Doug Hurley to the International Space Station. While it hasn't been publically announced, Ars Technica says that NASA is currently working towards a May 7th launch of Crew Dragon, but that date is lucrative.

Above is a video SpaceX released onto their official Twitter account. The video is of the Dragon spacecraft, and according to the post, it's currently undergoing electromagnetic interference testing. SpaceX CEO Elon Musk originally said that Dragon should launch within the second quarter of 2020, and judging on recent reports, that estimation is quite accurate. Dragon will take to the skies sometime in April, May, June. May is most likely the month when a launch will happen.

A new discovery has been made in the world of astrophysics, but unfortunately, this has got people scratching their heads as it's broken any existing explanations.

Fast Radio Bursts (FRB) was first detected back in 2007, and while humans first came across them, then it was most likely that there were bouncing around the universe since it's creation. Now, researchers have detected some FRB's coming all the way from deep space, while the occurrence of FRB's is initially quite rare, that isn't what has got researchers both excited and puzzled. These FRB's are coming in the form of a pattern.

Usually, when an FRB is detected, its source is traced back to what is assumed to stars colliding with each other. What has puzzled researchers this time around is the pattern of the new FRB, as it suggests something else is going on out in the universe and that the source is pumping out radio energy in certain timing. Researchers from Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project detected the FRB back in 2019. Then in January 2020, they published a paper detailing that they found more than one burst from the source.
