We have different blood types because of our Immune System.
Our red blood cells have protein markers on the outside of their membranes, called Antigens.
They can recognize whether cells are foreign or belong to your own body.
Now when the Immune System detects Antigens that aren't familiar, it releases Antibodies to tag and fight the invaders.
There are two main types of Antigens - A and B. And these determine your blood type!
There are four main blood types - A, B, AB and O.
Depending on your blood type, you either have only A Antigens, only B Antigens, both, or neither.
When receiving life-saving blood transfusions, the blood type is very important.
Someone of type A receiving type B blood could result in the blood clotting, because the body doesn't recognize the blood's Antigens and trea
Technology has improved our lives in so many different ways - can you even imagine the times when you were not able to tell your friend you'll be 10 minutes late because there were no mobile phones, and when you were not able to google anything at any time and actually had to use books to research!
It seems like there's an App for everything nowadays, so why not use Apps to enhance your productivity even more?
These apps will help you work more efficiently, procrastinate less, remember things, keep track of your tasks and progress, keep a digital notebook, and manage your calendar.
In the end, everybody has to find out what works best for themselves, but I definitely feel like apps can help you be more organized and productive since we spend so much time on our electronic devices anyway!
Wunderlist is a simple, beautifully designed App that lets you create and manage to-do li
Laughter is the best medicine - we've heard this saying a thousand times, but it's actually very true!
Smiling and Laughing are our body's reactions to positive emotions - it leaves us feeling happy and content.
But laughter can actually have a lot of other, indirect effects on our health that you might not be aware of!
Laughing reduces the levels of stress hormones like cortisol, and therefore help us ease tension and stress.
Also, the effects on our body help reduce the physical symptoms of stress, like tense muscles as well.
Laughing can actually be a full-body workout - I guess we've all experienced la
In Sci-Fi movies and videogames, we often see futuristic weapons like lasers, plasma shields or long-distance sniper rifles.
Disclaimer: I'm not promoting the use of weapons, nor am I a lover or expert of weapons, this topic just caught my attention because of the futuristic aspect and the advanced technology that's already being used.
The railgun is a new technology that uses electromagnetic forces instead of gunpowder or bullets to shoot.
The innovation is still fairly new and cost over 500 million dollars to develop.
A railgun is able to fire a projectile with a speed of 4,500 mph !
It works by building up an energy store, and then capacitors are channeling the energy along two individual rails which have either a positive or a negative charge. This creates an electromagnetic force which propels a 25 pound proje
Air pollution in crowded cities is getting worse and worse.
We have more people, more cars, more emissions - but not enough plants!
vertical forestis a concept by Italian architect Stefano Boeri.
It's essentially a skyscraper covered in trees and other different plants.
The dimensions are fascinating: there are over 1,000 trees on each tower, as well as 2,500 plants and shrubs.
It has taken a team of Botanists over 2 years to carefully select the different local species of plants, and their location on the tower.
On flat land, each Vertical Forest equals, in amount of trees, an area of 7000 m2 of forest. In terms of urban densification the equivalent
Good posture is one of those things where everyone knows you should improve it, but it's quite hard to make long-term changes so many people just kind of accept the fac that their posture isn't that great.
This leads to several different health issues, the most common one being back pain!
Well, why is posture so important anyway ?!
Our body is exposed to many different stress factors in our daily lives, for example carrying weight, sitting or standing for long periods of time, or sitting in an awkward position.
And the most consistent impact is actually gravity!
Our body has to maintain a correct and healthy posture, so that those factors mentioned above won't harm it too much!
Bad posture m
Almost everyone can relate to this: You're at a restaurant and just finished your main course.
You're absolutely stuffed and couldn't take another bite!
But as soon as you take a look at the dessert menu, a chocolate mousse or a piece of cake suddenly sounds very appetizing and once you start eating the dessert, you definitely have enough room to finish it.
So why is it that we often feel so stuffed after finishing one meal, but we could easily eat something else that has a different flavour?!
It's commonly referred to as
***dessert stomach***, but there's actually a scientific reason for it.
So sometimes, we might just feel full, but actually our brain isn't being stimulated by this type of food any
Social Media is changing us - the way we live, the way we communicate, and the way we think about ourselves.
Selfies have become so popular in the last couple of years, that it's even hard to imagine a world without it.
A few years back a selfie seemed like a strange new word that no one really used, but nowadays everyone knows what it means.
Since this has become such a huge phenomenon, more and more psychologists are studying social media and its effect on our life.
Posting so much of ourselves online, and of course, only certain things that represent us in the right way, has been closely linked to narcissism.
Studies by the Australian National University have shown that 75% of all selfies are posted by women, and 10% of people are doing it purely to build an online following and receive paid sponsorship d

The confirmation bias describes a psychological phenomenon.
It means that once we have formed an opinion about something, we embrace information that supports this idea, but ignore anything hat doesn't go hand in hand with our opinion.
And this can be applied to many different situations:
If you already dislike someone, you are much more likely to highlight every tiny mistake they make, and don't acknowledge if they achieve something positive.
If you want something to be true, for example you want to believe that your partner didn't cheat on you, you are more likely to ignore or look over small evidences that might otherwise prove you wrong.
If you hear a rumour about someone you like, you are probably not going to believe it, but if it's about someone you dislike, you will think "I always kne
