The future of information storage: DNA

Dr Robert Grass, Senior Scientist at ETH Zurich, and DR Reinhard Heckel, Postdoctoral Researcher, are working on a way to store information in DNA. DNA is very resilient and it can also withstand space travel as an experiment with plasmids in 2011 has shown us: a series of plasmids have been put on the outside […]

Check the list of 5 misconceptions regarding evolution

I’ve see this first on Science Alert. The infographic from below was created by Molecular Life Sciences. The 5 misconceptions are: 1. it is just a theory: theory means fact in science 2. survival of the fittest: nope. Better say: be able to reproduce and ensure the survival of the population. Nothing to do with […]

Salt, Diamonds and DNA: 5 Surprising Facts About Crystals

Reactions created a new video about crystals and how they behave. Did you also knew that the DNA, while an acid, has a crystaline structure? 2014 is the year of cristalography and Reactions teaches us 5 things about crystals. Crystals are materials in which the molecules have a unique arrangement called crystal lattice, a very […]

Science – what are polymers?

Polymers are substances formed from many basic compounds called monomers. If you have a given molecule and are able to insert many such molecules to form a fully functional bigger molecule, then you have a monomer in place. The DNA, RNA, tons of types of plastics and cellulose are polymers. They all are build from […]

Veritasium: the information that makes the diffrence between me and you can be stored on a floppy-disk

We, humans, share almost all the genetic code with every other human being on this planet. The total information in the DNA that makes us, well US, can be stored on a floppy-disk, in about 1.5MB of information. That is the amount of information that is DIFFERENT from human to human. The total information contained […]

If we’re evolving why are there apes?

As IFL Science showed on their Facebook page it is because we didn’t evolved from apes, but because we and the apes have a common ancestor, way back million o years. How coudl the scientist find something like this? DNA, that freaking 2 meter lon acidic molecule that holds the key to all life on […]

Veritasium: why women are stripey

Veritasium explains what DNA is and how the genetic code of women gets to be divided inside their body. The extra X chromosome the women have in XX, as opposed to XY in men, will play a role in how stripey the cells of a woman will be. If the X chromosome that came from […]

Are you alone in the Universe? Science says NO!

And why is that? You are not really alone, scientifically speaking, because you share a lot of things with the entire Universe. You share DNA code with all the living things on Earth, you share atoms with the Sun and the planets and you share a ton of characteristics with the people in your own […]

Genetics are freaking awesome: baboons with two hearts, pigs with human DNA

Hank Green, from SciShow, explains how the researchers were able to take the heart of a pig and insert it into a baboon. For this to work they needed to also engineer the heart to not generate certain proteins that are strangers to the human body. The issue with 15% of the transplants is that […]

Why don’t we live forever? DNA, that is why!

DNews explains why we get old and we die. It has to do with the telomeres, the edges of the chromozomes that are used as a buffer between the chromosomes and other chromozomes. Also, these telomeres shrink as the cells are diving so that, after a given time, those telomeres will vanish and the DNA […]
