UnknownDear Readers, welcome to Noughty Science 2.0!

What did we change?

The blog has a brand new image and logo. We reorganised the menu, added two new sections (“Outreach Events” and “The Funny Corner”), videos and comics. We also created a YouTube channel, in which we can post videos with our 3D logo animations. From now on you can also download the Noughty Science app on your Android phone, to be always up to date with our news!

What are you waiting for? Visit our blog and let us know what you think!

The mystery of colour change in the Statue of Liberty

The Statue of Liberty is one of the main and most famous attractions in New York. Most of us saw it in pictures as a beautiful green impotent monument.

However, this statue has not been green from the beginning, but its colour comes from chemical reactions between the material of the statue and the atmospheric agents.

How does this happen?

This colour change happens over time because this glorious statue is covered with a copper patina. Copper has a brownish colour and it reacts with the oxygen in the air forming copper oxide, which has this characteristic green/greyish colour. The same could happen to your pennies if you expose them to the air for some time!

Superhero multifunctional eyeglasses

Thinking about those magic glasses you always wanted that could record relevant information?

Well….They could be reality very soon!

A recent scientific article published in ACS Applied Materials Interfaces reports multifunctional eyeglasses that can detect and record biological functions such as physiological activities, behaviours, posture, electroencephalogram and electrooculogram!

Bu there is more….Such electronic glasses are fabricated by 3D printing and can be therefore customised and personalised.

How many molecules can exercise change in your blood?

With summer at the doors and the nice weather outdoor exercise is a great way to spend our time!

We all know how beneficial it is, but have you ever wondered what happens to the body during exercise? Researchers at Stanford University have found out that a single exercise session can alter almost 10.000 molecules in your blood! Can you believe it?

These are molecules involved in different mechanisms such as metabolism, feeling, appetite, immune response and inflammation.

Our blogger Rodolfo recommends “Endurance” by Scott Kelly.

Rodolfo says “I think the books may be a very good reference in these hard times, as it describes the daily life of the astronaut Scott Kelly who spent 1 full year at the International Space Station (ISS) . It is interesting to see how he was spending his time in confinement at ISS without losing his mind”.

Maybe this is the perfect time to give it a go!

 

Making plasma from microwaved grapes

This week post is about an interesting experiment to watch and not to try at home :-).

It shows how a bisected grape can produce plasma in a microwave. How does this happen? The scientists who created this video explained in the comments that “A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other creating a maximum of electromagnetic energy where they touch. This creates heating, sparks, and plasma, which is further fed with energy directly by the microwaves”.

Curious to see how they did it?

The composition of seawater

Hello everyone!

New week, new post! And since we are now moving towards summer, what is better than a day at the beach?

Imagine to be in a beautiful beach, enjoying the sun, the sand and the fresh water….Have you ever wondered what does seawater contain?

Well….definitely salt or what we know as sodium chloride (NaCl)! The concentration in seawater is quite high and changes depending on geography….. What else?

Actually there are more salts such as sulphates, carbonates and other components such as amino acids and microbial components!

Find out more about seawater components in these articles:

The chemistry of viruses

virusIn these times talking about viruses is very popular!

But they have been studied for a very long time! Have you ever wondered about the chemical composition of a virus? Viruses are very simple entities mainly composed by proteins and nucleic acids and that’s why some people debate over them being living organisms or not! In some cases these contents are protected by a lipid layer that acts as an envelope.

The chemistry of viruses has been known for a long time now….

Jump back into the past and read this interesting article from 1954 or this book chapter from 1963!

 

UnknownDear readers,

we have been quiet for a long time, but we are now back and look forward to talking about science again!!

We hope you didn’t miss us too much, but if that was the case, we are here again to share with you the latest news from the scientific world with one post every week!

Stay tuned and keep following us!!

Science and fun at YorNight 2020

Our blogger Carmen Piras took part in the organisation of a stand at the YorNight 2020, a day full of scientific activities open to the public and organised by the University of York (February 2020). Carmen and her colleagues from the University of York performed many different experiments with hydrogels!
