BIOSPAIN 2014

Imagen1Last week we went to the Biospain Congress of Santiago de Compostela, it´s an international congress of biotechnology where a lot of people that work or only likes this world can go and see all the stands with machines, new products and presents for the public, a lot of presents for the public.

We left the school at 8:45 and at 9:20 other students of other school got on in the bus because we had to snone it (not enough money). When we arrived at the building of the congress our teachers introduced us to the other pupils of the Pondal, it was a very embarrassing situation, and we couldn´t ask them their telephone numbers!!! (Thank you Ana and Angeles!!)

Then, a woman presented something about what we were going to see and we entered to the event building with our partners. The first thing which we did was the stand of the principal partner, I remember that was the Xunta or from the Spanish goverment.

We walked to all the congress with the woman explaining something about each stand. After these 3 presentations about biological things started and we had permission to be there. They were 30mins each and these were three, total 1h 30mins. The first  conference attended was about the reaction of the body to artificial organs, the second we attended was about another problem related with the human body and the third we attended was about 3D printers and their role in our health

The final part was my favorite part because we could visit the congress with total liberty, the first thing that we did was have a coffee from the buffet because we were very tired!!

It was very interesting and funny, I hope that we will be in another congress!!!Imagen2

BIOSPAIN 2014

BIOSPAIN 2014: Santiago de Compostela.

The last 26th of September we visited Biospain, the biggest congress about biotechnology in Spain. It was organized by Asebio (Asociación Española de Bioempresas). This congress was celebrated in Santiago de Compostela, the capital city of Galicia. This was the 7th international congress, in Spain.

Each year it is celebrated in a different place, one year it is in South America and the next year is performed in Spain. A lot of companies participate in this meeting of biotech, companies from Spain and from all the world, because this way they can advertise them and they also share information with people who is interested in this topic. We could see many varied stands from companies related with things such as; agriculture and medicine.

 Most of them told us something about the thing that they have discovered or they have improved and why they do this. We learnt many uses for biotech, now we know that this is really useful and very important nowadays.

After the visit to the stands we assisted the conferences and some spokesman from important companies explained to us what are they working on now. One of the most important topics was the 3D Printers, they are going to print organs to transplant, this has a lot of advantages, for example this way you don’t need donors. The technology is developing all these machines but they also need a medical component to have the appropriate results.

One of the problems that all of them have is the financing and they cannot improve in some things because the companies don’t share information.

In my opinion they should work together to advance faster. I think most people don’t know many things about biotechnology and about the advances of these companies. Biotech is important in almost all fields and it also can help the people. So, thanks for Asebio and all the companies that are working with biotech. The next year this meeting will be in Chile, I hope that many people can assist, if they visit this place they will learn new things.

SANTI´S CONFERENCE

 

Alberte Fernández Castro 3º ESO A

Santi is an expert in sports nutrition and a Galician champion of bodybuilding. Two weeks ago, he, and another nutrition expert, came to our institute to give for us a  little conference on health and good nutrition.

He started with the importance of drinking a lot of water, he reminded us that we must drink a lot of water and he showed us the problems of other drinks. One bottle of soda has  a lot of sugar. A clear example is a simple bottle of Coca-Cola that has twelve cubes of sugar. Many are not aware, in cola there is a substance called “folic acid” that works like natural substance of our body that prevent us for vomit.

In another part of the conference, he talked about the importance of the proper use of salt. He recommended using flaky salt for cooking, because usually, we use distilled salt. Flaky salt is a little more expensive than the distilled salt but it is more healthy.

Another important point that Santi talked about is the importance of consuming “living food”. Living food is a term that Santi use to refer to the food with a lot of nutrients. A lot of the food that we bought in the supermarket doesn’t have nutrients because, prior to its sale, it passed for a complex conservation and adaptation process that allows for more time in the supermarket.   

He also talked about the importance of fish, eggs, vegetables and having a good breakfast. For breakfast he recommended having a piece of fruit, eggs, perhaps a bit of milk and   some cereals. He reminded us of the important of having “antioxidants” and he gave us a trick: the foods that have a more intense color are the foods with more “antioxidants”. For example, chocolate, black olives…

Another example, the fish has a special acid called omega 3 that you only can find in fish, so it is an important to eat food.

We liked this conference very match and we want to see Santi again!!!

Finally I present this image that represent very good Santi´s words about the sodas very good!!

The cells

Robert Hooke, a British scientist, discovered the cells. He decided to call them cells, because he thought that they are very similar to the small parts that form a honeycomb. Matthias Jakob Schleiden and Theodor Schwann developed the first Cell Theory. In this theory they said that all persons are formed by cells. Cells are the main component of living beings, so if we didn’t have cells we wouldn’t be alive.

Cells are very small organisms that cannot be seen without using a microscope, a device that allows us to see small things in a larger scale. Zacharias Janssen developed this device in 1950. We can classify the cells in two main groups, animal cells and plant cells; we have animal cells. The cells are formed by other even smaller elements: the atoms that form all the things that exist in the Earth, and the molecules that are groups of atoms.

Inside a cell we can see, with help of the microscope, different parts called organelles. The organelles allow the cell to carry out its vital functions. In the cell we also see the DNA, which is a substance that controls everything a cell does, and if we observe a eukaryote cell, it has this substance in a nucleus, but if we observe a prokaryote cell, it hasn’t got DNA in the nucleus.

In our body there are many types of cells. Cells of the same type form tissues, like the nervous tissue, the covering and lining epithelium or the blood… and these are joined forming organs like the heart, the stomach… and these organs form systems and apparatus, like the circulatory system, the digestive system, the locomotor apparatus…

 

 

All these organs and systems allow us to do real things such as eat, breathe, relate with other people…

I think that it is very important that there are people who dedicate all of their life to the investigation, for example Robert Hooke or many other scientists.

Smoking hurts teen girls’ bones.

Lower bone density likely in adolescents who smoke cigarettes.

High school might be a bit early to start thinking about bone loss and osteoporosis, but a new study finds that teenage girls who smoke may put themselves on a trajectory to having less bone mineral than those who don’t light up.

While bones regenerate and remodel nonstop over a lifetime, the teen years are crucial to developing a strong, dense skeleton.

Failing to build adequate bone strength in adolescence could jeopardize a young woman’s ability to fully accumulate a “bone bank” that will be needed when she someday reaches menopause and begins to lose bone mass, says study coauthor Lorah Dorn.

Dorn and her colleagues recruited 262 healthy girls ages 11 to 17. By the time they reached age 19, daily smokers in the study had fallen a full year behind nonsmokers in bone mineral accrual, the authors note.

Kenneth Ward, a clinical-health psychologist at the University of Memphis School of Public Health in Tennessee, says he was impressed that the researchers could identify smoking as a risk factor in such a young group.

The results also seem to concur with studies done in adults, Ward says. A 2001 review by Ward and colleague Robert Klesges of adults’ bone density estimated that smoking increased the risk of a vertebral fracture by 13 percent and hip fracture by 31 percent in women.

Still unclear, Ward and Dorn note, is exactly how smoking contributes to the reduced bone mineralization.

http://www.sciencenews.org/view/generic/id/346875/description/Smoking_hurts_teen_girls_bones

In my opinion this is terrible!! I mean, we know that smoking is bad for our health: our nervous system, our lungs…and now we know that it’s also bad for our bones!! Aren’t those reasons enough for us to realize that smoking will end our lives!!? The trick is not to start.

Why don’t penguins fly?

It is a hard journey that has left biologists scratching their heads over why the birds did not keep their ability to fly as their diving ability evolved. A new study argues that birds cannot be both masterful divers and flyers, because flying abilities must weaken as the animals adapt to diving.

Rather than looking at penguins, a team led by biologist Kyle Elliott at the University of Manitoba in Winnipeg, Canada, examined species of diving seabirds that still have some ability to fly. These included the pelagic cormorant, a species that propels itself underwater with webbed feet, and the thick-billed murre, which flaps its wings underwater to swim.

“Basically, they have to reduce their wings or grow larger to improve their diving, and both would make flying impossible,” says Robert Ricklefs, an ornithologist at the University of Missouri–St. Louis.

penguins, penguins flying, why penguins cannot fly

Yet questions remain over just how much the birds’ energy costs are related to inefficient flying and swimming, and how much they are related to staying warm. So I guess that it won’t be today when we’ll find out exactly why penguins can’t fly,but we can always hope that the species will evolve and leave us with flying penguins… who knows?

The mood of disease development aid

Current studies are showing that the development of many physical illnesses such as cancer is due in large part to the state of mind of a person.

Emotions are critical to health, some studies find that the central nervous system and the immune system communicate, this means that emotions and body are not separate but very interrelated.  The role of emotions is not limited to lead role or be the cause of the disease, but also influences their development, aggravation and chronicity.

Among the most studied emotions are anger, stress, depression and anxiety. A common definition that everyone agrees on is that emotions are adaptive processes.  All these emotions act on different hormones, causing changes in our bodies that make us more sensitive and influence various diseases. An example are the studies linking stress to cancer. It has been demonstrated that this may influence both the source and the disease course.

Naturopathic profession have to teach people to keep health states by natural methods, not to create a dependency on a tablet mostly chemistry and that greatly benefits very few.

In my opinion it is very interesting to know this as it can lead to finding more cures for these diseases while methods to prevent them.

ROSA.

It’s name is ROSA and it’s a new robot to operate epilepsies that previously had no treatment. The Hospital del Mar in Barcelona has done five operations with the robotic arm that increases the accuracy and effectiveness of interventions to remove the areas of the brain where electrical discharges originate causing seizures. This new technology allows to operate on patients with “very complex epilepsy for which until now did not contemplate surgery,” said Dr. Rodrigo Rocamora, head of the Epilepsy Unit of the Hospital del Mar.

The robot ROSA has allowed physicians to place an average of 12 electrodes in each patient, which allows to study very precisely the focus of the origin of the disease and to define brain function areas that should be removed to be able to cure this disease.

 

“The electrodes are less than a millimetre in diameter and they record the electrical activity deep in the brain,” explained Gerard Conesa, surgeon in charge of these interventions.

“This technology allows the brain to process images on a computer system and run the paths to place the electrodes inside the brain, preventing damage to veins, arteries, or other sensitive areas,” said Conesa. One of the first people intervened is a Bolivian woman of 28 who is four months without suffering any crisis, when suffered before being operated on an average of three per month. The robot can minimize risk, thereby increasing the percentage of patients that can be operated.

Some 400,000 people have epilepsy in Spain. Surgery is needed when the patient doesn’t respond to drug treatments, which occur in 30% of cases. The cure to epilepsy is getting closer and closer everyday.

The two-faced cat

As National Geographic says, probably one of the most famous cats in the world is Venus, a three-year-old tortoiseshell with a peculiar face. One half is black, with a green eye, but the other one has orange tabby stripes and a blue eye.

At first, scientists thought that Venus could be a chimera, a fusion of two embryos whose cells contain two types of DNA, a normal formation in male tortoishell cats. However, Venus is a female cat, so she is not necessarily a chimera. To find out, it would require genetic testing on the two halves of her face.

But it´s not the only mystery surrounding her. She has one blue eye, but cat´s eyes are typically green or yellow, except on siamese or completely white cats, that can be able to have blue eyes, but Venus only has a little white patch on her chest, so nobody can explain it yet.

Venus the cat

In my opinion it´s a really strange case, because it´s very unusual to discover that kind of “mutations”, so it´s also very useful for scientifics to learn more about genetics.

The day after tomorrow

In the Earth´s past there were a lot of climate changes that left a lot of evidence. The majority of scientists agree with them, but what would happen if in our time was  the beginning of an mini ice age? In spite people believing that the planet is heating up,  the evidence about cooling and the beginning of an ice age are growing.

Real causes of ice ages

Some scientist mistakenly think that C02 is the most important cause of climate change. It is true that C02 has a  greenhouse effect but it is so weak that almost doesn´t produce inmalances in climate. But what is the cause of ice age? The answer lies in the variations of the solar cycle.

2000 years ago in Roman times termperatures were higher than today but solar radiation was also higher. In Dalton´s and maunder´s minimum, the last mini ice age  periods, solar activity was extremetly low and sunspots were almost non existent.

we can see on this video the solar cycle is the more important cause of climate change:                                           embedded by Embedded Video

Evidence

The head of the space research sector of Pulkovo Observatory of the Russian Academy of Sciences,  Dr. Habibullo Abdusamatov says that the planet is begining to cool. “Studing solar cycles we can calculate  the next change in temperatures, we have evidence that the temperatures will begin to drop dramatically from 2014, reach its peak in 2055,” says the researcher.

Some shocking news are taking place on this days. On the 10th January 2013 ther were reports that it had snowed in  Saudi Arabia, Libia and Jerusalen also appeared snowcapped. Another one said that an unusual cold wave struk Egypt. In Canada there were glaciar temperatures of -40ºC since three years ago and in the northeast of United States on the 24th January 2013 temperatures dropped to -30ºC. In China, one cold wave showed lowest temperatures for 3 dechades , and it froze the sea trapping 1000 ships.

In Spain, these days temperatures achieve lows that that trap a multitude of vehicles on motorways and leave a Siberian scene. Some animals like reindeer are moving to lower latitudes in North America. A lot of bees die and migratory birds change their routes. In some zones like Ontairo fauna and flora are  already glacial. These news items are some of many evidences of this global cooling produced by solar cycle.

Consequences 

The studies of solar cycles prevent the arrival of the double solar minimum of Gleissberg in 2030. The drop in temperatures will bring to planting areas  will be considerably reduced. In addition to problems with food, it will be more difficult to extract oil and gas in the north. Problems will arise with the provision of heating the population. “the temperature drop will touch many, almost all, but in general the northern countries,” said the Habibullo Abdusamatov above-mentioned.

I think that people need to know the truth about things that happen and wake up. I hope they analise this information and think of the conclusions.
