Science reveals what humans will look like in 1,000 years and it’s bizarre

Have you ever wondered what humans will look like 1000 years from now?

It’s a fascinating question and one that science can finally answer.

This video, created by ASAP science, may be a little weird at first, but it’s incredibly interesting.

The video says that future humans will have vastly different faces, eyes and skin color as we adapt to the changing environment thanks to climate change.

Watch the video below to find out how your future cousins will look like:

If you can’t watch the video, here are the conclusions the video came up with:

Chances are, we’ll be a lot taller. In 1880 the average American male was 5 ‘7”. Today, he’s 5’10”.

It’s also possible that we’ll merge with machines to better our hearing, health, taste, eyesight and more.

For example, at the University of Oregon, they are developing bionic eyes that help the blind to see.

It could be possible that this technology becomes a tool for seeing what we currently consider invisible, like different energies of light.

Our genes will also evolve to aid our survival.

As an example, a study found that a group of HIV-infected children in South Africa live healthy lives. It was found that they have a built-in defense against HIV that prevents the virus from advancing to AIDS.

It’s also likely we could control our genes and DNA to the point where we make ourselves immune to disease.

Thanks to globalization, the 7,000 human languages that are spoken today will likely dip to under 100.

Also, the globe’s rising temperature will likely play a role in our evolution. Darker skin may become an evolutionary advantage as it protects against higher UV rays.

Taller and thinner bodies will be better at dealing with excess body heat.

Also, mutations may occur, which could lead to a new eye color or unique abilities. For example, a man today has the unique ability to digest anything, even metals and wood, as a result of a genetic mutation.

We may also engage in artificial selection and choose genes that we want our babies to grow up with, such as genes to avoid diseases and genes that allow us to be smarter and physically better looking.

However, this lack of diversity could lead to future problems that we’ll struggle to deal with.

Whatever happens, one thing is for certain:

Humans will continue changing – and the faster we change and branch out from Earth, the better chance we have of outrunning extinction.

A 75-year Harvard study has revealed the most important factor in human happiness

A 75-year Harvard study has revealed the most important factor in human happiness

Have you ever heard of the Harvard study that ran for 75 years to assess what makes us happy? It’s a revolutionary study in psychology.

It followed the lives of two groups of men for over 75 years, and it now follows their Baby Boomer children to understand how childhood experience reaches across decades to affect health and wellbeing in middle age.

So what keeps us happy and healthy as we go through life? If you think it’s fame and money, you’re not alone – but, according to psychiatrist Robert Waldinger, you’re mistaken. As the director of a 75-year-old study on adult development, Waldinger has unprecedented access to data on true happiness and satisfaction and he lays it all bear in the Ted talk below.

So what is the number one factor in your happiness and wellbeing? According to Waldinger:

“The clearest message that we get from this 75-year study is this: Good relationships keep us happier and healthier.”

Yep, the biggest predictor of your happiness and fulfilment overall in life is, basically, love.

Specifically, the study showed that having someone you can rely upon helps your nervous systems relax, helps your brain stay health and reduces emotional pain.

The data also clearly found that those who feel lonely are more likely to see their physical health decline earlier and die younger.

“It’s not just the number of friends you have, and it’s not whether or not you’re in a committed relationship,” says Waldinger. “It’s the quality of your close relationships that matters.”

It doesn’t matter whether you have a huge group friends, or if you’re in the perfect romantic relationship, it’s the quality of the relationships that counts – how much depth and honesty exists within them; the extent to which you can relax and be seen for who you truly are.

This a very good reminder to prioritize authentic connection with others. Because the data is clear that, in the end, you could all have the money you’ve ever wanted, but without loving relationships, you won’t be happy.

Africa set to “leapfrog” over coal and choose renewable energy instead

Africa set to “leapfrog” over coal and choose renewable energy instead

Even though American leadership appears to be losing its motivation to tackle climate change, there’s still a good chance the Earth can be saved.

Climate activism has risen rapidly since Trump pulled out of the Paris agreement and global cooperation and market forces are causing renewable energy to become more popular than ever.

It’s no secret that the developing world are still relying on coal. While India has seen huge investments in wind and solar power, they are still projected to be heavy polluters for some time to come.

However, the African continent is taking a different approach. According to the executive director of the International Energy Agency (IEA), it’s likely that Africa will skip the use of coal all together and focus on using clean energy electricity sources:

“When it comes to Africa, I think we will see something for the first time: Namely, Africa will bring electricity to people by mainly using renewable energy and natural gas.”

Africa consists of around 700 million people without any source of electricity. Check out this tweet from Afrobarometer which shows how many Africans are connected to an electric grid:

This means that the governments in Africa can choose any energy source they like. While coal is generally cheaper, the effectiveness and ease of availability of renewable energy is positioning it to be more enticing for most African countries.

It’s not just Birol who is predicting this. A study from 2016 analyzed energy trends in Africa and found that in 21 countries, renewable energy could fulfill the nations’ electricity needs by 2030.

However, it’s important to realize that natural gas will still be a major feature in Africa’s short-term future – a fact that is unavoidable due to its cost and availability. Though, natural gas does have a lower carbon footprint than oil or coal.

Of course, there are obstacles in the way. For renewable energy to become prominent, there’s going to have to be a lot of cooperation between African countries – something that has proved difficult in the past.

Also, the electric grids that exist right now desperately need an upgrade.

However, if this prediction takes hold and Africa leapfrog over coal and choose renewable energy instead, this would mean an extra billion people use clean energy rather than coal.

A 75,000-mile-wide HOLE has appeared on the sun – and experts warn of blackouts on Earth

A 75,000-mile-wide HOLE has appeared on the sun – and experts warn of blackouts on Earth

Do you remember 2012? The heady days leading to the final count down and the end of life as we know it?

Apart from the Mayan predictions, it turns out there was a very real reason for panic in that year. 2012 was the year of Earth’s lucky escape. We had a close shave with a super solar storm – the most powerful on the sun in 150 years. We were lucky then. Had that solar storm occurred a week earlier, earth would have been in the line of fire.

Let’s hope our luck holds, because at this moment we are facing the same peril.

NASA has found a massive 75,000-mile hole in the sun. The video below by NASA’s Solar Dynamics Observatory with footage taken from July 5 to July 11 shows an active region — an area of intense and complex magnetic fields — that has come into view on the sun. According to NASA it seems to be growing rather fast.

Labeled AR2665, the sunspot could potentially cause havoc here on earth.

Sunspots are darker, cooler areas on the surface of the sun, caused by interactions with the sun’s magnetic field. They tend to appear in regions of intense magnetic activity, and when that energy is released, solar flares and huge storms erupt from sunspots.

The more intense the interaction with the magnetic field, the more likely it is for sunspots to appear. The problem is that when all that energy is released, solar flares erupt that send out giant bursts of light and radiation called coronal mass ejections (CME) out into space.

These huge sun flares could cause radio blackouts and electricity shortages in some areas, disable communication satellites and disrupt GPS systems.

Such sunspots are a common occurrence on the sun, but are less frequent as we head toward solar minimum, which is the period of low solar activity during its regular approximately 11-year cycle. This sunspot is the first to appear after the sun was spotless for two days, and it is the only sunspot group at this moment, according to NASA.

“The spots are like freckles on the face of the sun, they appear to be small features, but size is relative: The dark core of this sunspot is actually larger than Earth.”

A really large one can send us back to the dark ages if it knocked out all power on earth.

One recent study predicted solar storms could cause massive blackouts across America and cost the country up to $41.5 billion a day.

What are the chances of that happening? Should we worry?

Physicist Pete Riley who published the paper On the probability of the occurrence of extreme weather events, has calculated that the odds of a solar storm strong enough to disrupt our lives in the next ten year is about 12%.

In January this year NASA announced a breakthrough in predicting solar storms, which will help give Earth an early warning. That should put our minds at rest. Or not.

Scientists discover we have a “force field” around our bodies and you can feel it

Scientists discover we have a “force field” around our bodies and you can feel it

Have you ever had the sensation of suddenly closing your eyes only to realize afterwards that an insect was heading straight for your face? Your body reacted instinctively before you had time to think because our brains are aware of the space around us.

This phenomenon might have something to do with a personal force field that we have around us.

Neuroscientists from the Karolinska Institute in Sweden have used a twist on the rubber hand illusion to help people actually feel this force field.

Here’s the proof:

Hard neuroscientific evidence on the phenomenon appeared in the late 1990s in animal studies when Michael Graziano of Princeton University, New Jersey, and his team recorded the brain activity of monkeys and found that some neurons fired not only when an object touched part of the body, but also when the object approached it, reports Anil Ananthaswamy for New Scientist.

Now, neuroscientist Arvid Guterstam of the Karolinska Institute in Stockholm has devised a clever way to help humans sense the peripersonal space around them. They used the well-known rubber hand illusion, but took it further.

The original illusion involved an inflated rubber glove, a flat piece of cardboard and two small paintbrushes. The hand is placed on the table in front of the volunteer and their real hand is concealed. When someone strokes that fake hand and real hand simultaneously, most people become convinced after a while that they feel the brush strokes on the rubber hand as if it is their own hand.

For the latest experiment, which involved 101 adults, the researchers didn’t stroke the actual rubber hand, but move the brush in midair above it, while stroking the real hand with brush strokes, reports Ananthaswamy.

Most volunteers reported feeling a “magnetic force” or “force field” between the paintbrush and the rubber hand below – as if the brush was encountering an invisible barrier. This time the volunteers also felt a sense of ownership of the rubber hand, writes, Ananthaswamy.

“We can elicit this bizarre sensation of there actually being something in mid-air between the brush and the rubber hand,” Guterstam, told New Scientist.

The sensation of a force field disappears when the brushstrokes are more than about 30-40 centimeters above the rubber hand, which seems to indicate the size of our peripersonal space.

Could there possibly be some kind of relationship between this force field that scientists have detected and the human aura that some people are able to see around people? Or are they completely different? What do you think?
