What is Biotechnology?

Perhaps you have heard of the term biotechnology and wondered what it is. You may think you know already – after all, the parts that make up the word are very familiar: bio + technology. You have seen the first part of the word in biology, antibiotics, all sorts of words. It comes from Greek bios, which means ‘life’.

As for technology, it is not just about computers and smartphones. Technology is the practical use of knowledge to create useful things and solve problems. You might like to think of it as tech-knowledge-y. So, taking it one step further, biotechnology is about using biology in technology.

We talked to Alessandra Iscaro, a biotechnology researcher at the University of Florence, Italy, and she explained to us what it is all about.

Amazing Libraries and Bookstores Around the World

What do you like about going into a bookstore or library? Is it the smell of the books, or the sight of the different coloured spines, waiting to be pulled from the shelf, so that you can dive in?

We have compiled a list of some of the most amazing libraries and bookstores around the world. Some of them you may have heard of, others are less well-known, but all of them made us smile or gasp in wonder. Which one is your favourite, and which library or bookstore would you add to the list?

Real Gabinete Português de Leitura, Rio de Janeiro, Brazil

Real Gabinete Português de Leitura pic by Mathieu Bertrand Struck

A building so remarkable that this one photo cannot hope to do it justice – more pictures here. This is the largest and most valuable collection of Portuguese literature outside of Portugal. The library was constructed between 1880 and 1887 – the facade was carved out of limestone in Lisbon, Portugal and transported by ship to Rio.

Early English – The Latin Alphabet

In our last post, we discovered the runic alphabet and the Futhorc, and now we are going to look at what came next. The Latin alphabet.

The Futhorc was gradually replaced by the Latin alphabet. However, it seems that the Latin alphabet was not perfectly suited to represent English, which contained sounds that did not exist in Latin, and so people adapted it with the addition of a few runes: thorn to represent ‘th’ and wynn to represent ‘w’, as well as a few adaptations in usage of the already existing Latin letters in order to make them better suited to representing English sounds.

Have you ever wondered…why leaves change colour in autumn?

Autumn is a season of change; the weather gets colder, there’s less daylight and leaves change colour and fall from plants. But why does this happen?

Why Do Plants Have Leaves?

Leaves contain a chemical called chlorophyll (pronounced KLO-ro-fil), which as well as giving them their lovely green colour also helps create food for the plant. The leaves act like tiny solar panels, and use the sun’s energy to convert water (from the ground) and a gas called carbon dioxide (from the air) into sugar and oxygen. This process is called photosynthesis (pronounced foto-SIN-theh-sis), and the sugar is what the plant lives on.

What is a Stick Bomb?

11-year-old Andre Jefferson explained stick bombs as being, ‘a kinetic chain reaction that is weaved together with jumbo popsicle sticks, that creates tension, and when you take one of the sticks out, it releases potential energy and makes it pop up about this high’.

If you are thinking ‘What?’ then watch the rest of his TEDx talk to find out what a ‘Stick bomb’ is and what makes them jump.
