THE IMPORTANCE OF THE MICROBES The word ‘microbe’ sounds scary, we associate them with the flu, ebola, flesh-eating disease... But microbes are more important than we think, they are essential for us. There are many things why the microbes are good for us; for example these three great things that microbes do for us: 1) Microbes play defense: microbes protect us from pathogens that attack our body. 2) Microbes boost the inmune system: Some microbes could potentially even help the body fight cancerous tumors. 3) Microbes protect us from auto-immune diseases: Microbial yogurt could replace insulin shots for people with the disease. Microbial disturbances could be at the root of other auto-immune disorders too. Written by: Rebeca López Bastidas Marina Sola Álvarez 3ºESO B
Questions and Answers ( by Laura Jiménez, Marina Utrera and Lucia Piernas) We have investigated a lot to try to find the answer to some interesting questions people don't pay much attention to. Here are our findings: Why is snow white? It's made of water and water is colourless. So how comes it turns white just by freezing? Snow is white because its molecules reflect back to us all the colours in the sunlight. It does not selectively absorb any particular colours. If I'm in an elevator and it starts to fall to the bottom of the shaft, can I jump up at the last instant and cancel the impact? It is easy to answer in one word, no. It is impossible. Remember Newton's Third Law of Motion. You may feel floating for a moment, but gravity has its way with you and you fall, along with the elevator. Physics Quiz Test how much you know about physics by trying our fun physics quiz. There’s a range of questions about topics such as energy, motion, friction, magnets, force, gravity and light.

Science Mysteries and Myths by Rocio, Paula and David Gutierrez Mysterious moais Problem: weathering Easter Island, in South Pacific Ocean, is dotted with hundreds of Giant Statues, called Moai. These statues are made up of volcanic rock. Many of them are partially buried under shifting soil, so only their heads are visible, that's why they are often referred as "Easter Island heads". Anyway, they have a crouching body, but with no legs. Pharaohs' tombs Cairo. Egypt. 4,000 years ago the ancient Egyptians built the tombs for the pharaohs. The blocks they used to built these tombs were cut out of limestone. The pyramids once had smooth sides but wind-blown sand has scared away most of their outer shell. The scientists have learnt much about ancient Egyptian culture examining the pyramids. And they discovered the pyramids were built to last
Ostriches do not stick their heads in the sand when threatened. Actually they don't bury their heads at all. When threatened, ostriches flop on the ground and play dead.
Your blood is never blue but rather dark red when it's not carrying oxygen. It only looks blue because you are seeing it through your skin.
People don't use "just 10%" of their brains. We use the entire brain for different processes at different times. We couldn't survive if we scooped out 90% of it.
You are not born with all of the brain cells you will ever have. There is ample evidence that the brain continues to produce new cells in at least a few brain regions well into adulthood, through a process called neurogenesis.
Lightning does strike twice. And some places, like the Empire State Building, get struck up to 100 times a year.
Dogs and cats don't see in shades of grey. They can see in blue and green. Dogs have a wider field of vision than humans but cannot see as far in front of them as we can.
Goldfish actually have pretty good memories. They can remember things for months, not seconds like most people say.
Sharks can and do get cancer. The myth that they don't was created by I. William Lane to sell shark cartilage as a cancer treatment.

Dangerous Household Products Ammonia and bleach Everybody usually has ammonia and bleach to clean their homes. They aren't dangerous because of the low percentage of pure gass they contain. But if you mix them, they will become dangerous. when they are mixed, there is a chemical reaction. The mix of the two gases produces carbon dioxide and you can't breathe. Mobile phones Most people use mobile phones in their everyday life. They let us communicate easily and do many other things. But they can be a very big problem. They emit electromagnetic radiation and it can produce a lot of diseases, for example brain tumor. Using butane gas as a fuel Many people use bottles of butane gas as a fuel, for example in the kitchen but it can be very dangerous. If there is a leak, it can burn easily. This can cause
an explosion and you could die. Houses with fireplace There are fireplaces in some houses, because they produce a lot of heat and you can also cook there. But if you aren't careful, you could have a big problem. When the fireplace doesn't have a proper ventilation and the place is closed, the smoke could fill the whole room and smoke inhalation could kill you. by Angel Botia, Alejandro Molina and Alberto Valdivieso
Tiger's last stand by David Quirante and Liam H. Rodriguez Now wild tigers live only in a small area of India, China, Eastern Russia and a few other countries. The reason why tigers are almost extinct is the illegal hunting to use tigers' eyes, whiskers, paws, blood , bones and tail. These parts of the tigers used in ancient medicine and cat farmers. 3000 years ago traditional chinese medicine (TCN) has used tiger parts to treat sickness and injury. There is an only way to save thse tigers: take measures against illegal hunting
A Special Activity: Science Theatre In the last magazine, we could see a section about voyages from the Earth to other planets. Our association called "Going home" is going to visit all the high schools in Granada carrying out an activity for the students. It consists in performing interactive science demonstrations for K-12 students on-stage. Science Theatre performers are undergraduate and graduate student volunteers and all performances are made free of charge. The group’s performances consist of arrangements from its catalog of more than seventy demonstrations in biology, chemistry, and physics. Pupils will be distributed into groups to take part in demonstrations. If you are interested to become part of this association, fill in the following form
by Elena Almagro, Corina Cobo and Maria Pe単alver There has bee a new discovery of a vaccine against tuberculosis Tuberculosis is an infectious disease that has been one of the biggest causes of death in the world. The process to create the new vaccine is very expensive and complex. Many scientists are working on this project and the money used to do research comes from public taxes. Besides, the bacteria is very difficult to handle, so the process is very slow and the laboratories where the project is being carried out work under high biological security regulations two types of preventive vaccines have already been made: one made of proteins, aimed at improving the immunity of good cells and the other one using BCG bacteria; its objective is make cells stronger.
