  • Save the bees

    Save the bees

    Continuing our article from the first edition.

    Our privileged geographical location has allowed 398 different species of bees to be found, according to the SIB (Colombian Biodiversity Information System), from the Caribbean region to the Amazon Basin and in most of the country’s thermal floors. A high figure compared to the other countries of the world. This generates the possibility of favoring the planet if adequate studies are conducted and there is support from the specialized professional for the analysis of the subject. Thus we will find stronger and more resistant species that can contribute to solve the colony collapse disorder.

    Most of the insects live in the Colombian Andes region, 2,500 meters above sea level. Out of these, at least fifteen thousand, are new or unknown species for science, on the other hand, the guide seeks to increase awareness of the importance of these native pollinators which are part of the Colombian biodiversity, so that we can value the environmental services provided by the bees to the Andean ecosystems. It is important to take appropriate measures to stop this phenomenon that seriously affects the environmental balance and puts at risk the global food system.

    For example, in England last year pesticides that include components of “Neonicotinoid” and “Imidacloprid”, which has been linked to the deaths, have been discontinued. In France, the use of “Gaucho”, a chemical associated with the bees mortality in this region was banned and “Imidacloprid” appears to be in its components. Studies are under way in Australia to develop genetically stronger and weather resistant bees and pesticides used in crops, as well as controls at airports to prevent the arrival and the spreading of the Varroa Mite.

    Taking into account that agricultural activity in Colombia is more intense, it is necessary to have much more controlled and specific environmental laws and policies that protect biodiversity. It is important to provide training and seek international support for the management of agrochemicals and their respective wastes, which if not managed properly can trigger a major environmental disaster. At present we Colombians think that bees are dangerous, because in some regions of the country, these insects are “Africanized” since they are a little more sensitive to noise and heat, however what they don’t know that this is caused by the stress of chemicals and the noise pollution that we humans beings generate. So we must be aware that every animal species exists for some reason, remember that bees are in charge of pollinating 90% of the crops in Colombia and the world.

    For the same reason, the entities in charge of this issue can increase the support to policies that promote the growth of wild flowers, ornamental plants and public gardens in the urban sectors, offering healthier and economic alternatives, generating space for the life of bees and other insects in urban areas.

    We can also seek international assistance working hand in hand with the universities to create projects that diminish the ecological impact and strengthen the ecological agriculture in the country.

  • What is Nano Technology?

    What is Nano Technology?

    Nanotechnology promises progress in the fields of health, energy and electronics; It is a revolution in every field of study.

    The “Nano technology” promises surprising advances in the fields of health, the energy and the electronics; it is a revolution in every field which promises to improve significantly the quality of our life. Microchips that can fit on the head of a pin, water purification with only one sheet of paper, artificial skin to protect ourselves from the environment, contact lenses with improved vision, robots that travel within the blood stream to treat diseases accurately; all that is not a part of a science fiction movie, they are the latest technologies and in development currently and all that is thanks to the science of Nanotechnology.

    This new science is making the electronic devices to become increasingly smaller, faster and with a lower cost; it is improving the science of medicine and health at a rapid pace. It is about building materials and machines by restructuring atoms. The exact unit with which this science is measured is called “Nano”, that is one billionth part of a meter. Richard Feynman, known as the father of “Nano science”, winner of the Nobel Prize for physics, 

    in 1959 proposed manufacturing products based on the use of these elementary particles. This technology is a new field of study that crosses all the boundaries of sciences, from philosophy to humanity in the discussions on its ethical implications. There have been significant advances and great changes are expected in a short time, there are currently “Nano sensors” that can detect symptoms of diseases by simply fingerprinting or blowing through a tube; the most sophisticated is a Nano robot with a miniature camera that can enter the bloodstream and take pictures at the speed of two frames per second of what is actually happening in our body.

    They are researching on another Nano robot which will travel the circulatory system with the goal of directly attacking the cancer cells, this would overcome the devastating treatment of chemotherapy that kills diseased cells which also heals but seriously causing harm to the patients. Also in the reconstruction of the tissues in the human body creating synthetic nanostructures that communicate with the cells through molecular messages, as if they were a part of the tissue being constructed.

    With these advances in medicine we will be able to have better preventive health, more accurate diagnoses, precise and personalized treatments, we can avoid using excessive drugs with serious side effects and annoyances. In the field of energy they are making great strides with the goal of using sustainable energy to avoid further damage to the environment. This science creates solar panels which plans to take full advantage of the powerful solar energy, covering the energy needs of the planet.

    To generate electricity with solar energy you need a solar light absorbing material and that can transform it in electrical energy; meaning to say a “Photovoltaic Cell” of crystalline silicon. Silicon is a semiconductor element of energy, by putting this material in the sun gives an electric current and 15% of solar energy is transformed into electricity. The goal of these latest studies is to increase the conversion rate of energy into electricity and make the silicon material more efficient.

    In the electronic field we have seen how chips are made smaller, with silicon and grapheme, materials which when reduced in size do not lose their chemical properties, which also improves the performance of computers and electronic devices. Gordon Moore, co-founder of Intel, said in 1965 that the number of transistors in an integrated circuit would double each year, the idea is that the devices would become smaller, with greater capacity and their price would also be reduced.

    Today we see that the “Moore Law” is a reality, electronic devices are becoming smaller, effective and getting cheaper. In the same way they have developed contact lenses to improve vision, 3d holographic movie screens that don’t require glasses and Nano batterias that just need 60 seconds to recharge themselves.

  • Is there life after death?

    Is there life after death?

    Today with innovative scientific discoveries we can find new ways of reanimating the people after the death.

    Death is an issue that today affects us all and scares us of the reality that it presents, it often distances patients from their calmness and makes them wake up in a world full of anguish and tragedy that not even our own brain can really understand. When this issue comes to our families, what we should do, is to let the person go on and let his soul rest to the point that he can find the peace he needs. In the past, the criteria for declaring a person clinically dead was lack of breathing and heartbeat.

    With the evolution of the technology, a method was used that allowed the artificial conservation of cardiac and respiratory responses in patients to revive them; over time scientific advances are surprising us more and more by all the discoveries that have made based on the death of the patient. We can describe death, as a condition when the body and the soul of the organism is separated, it is a mirror in which we contemplate the course of our life, the personal history, the ongoing dialogue of the spirit with the heart offers energy for action, offering a journey towards growth. Understanding this means that life itself is only a small period of our existence.

    Scientific studies have shown that after death there are possibilities of revival, cardiovascular surgeons are using an extreme freezing technique that allows them to stop the patient’s heart to undergo surgery, which will later give them a new life. This new technique is being utilized by specialists at the New Haven Hospital of Yale University in the United States, where they subject the patient to induced hypothermia to cool down their body from its normal temperature of 37 ° C to just 18 ° C. Dr. John Elefteriades, has performed several experiments with this new tool making all his operations a total success. This surgeon overcomes the difficulties of operating a heart which has been almost without vital signs, this operation lasts 45 minutes, it is a procedure which passes through the patient’s arteries and veins, filling it with blood while the freezing tempreture decreases the body processes of the person, John has sufficient time to perform the surgery without causing damage to the brain. Once they finish the operation they put the person in warm environment to restart their cardiac function with a defibrillator.

    “It is the most fascinating technique I’ve ever been exposed to in medicine, and it always seems like a miracle that it works.” For this surgeon to operate on a beating heart presents great challenges, some cardiovascular operations are not only difficult but impossible, if not achieved the heart stops, but they have managed to save many lives and revive others. The extreme freezing of the body puts the patient at both the risk of dying and recovery, so deep hypothermia had not been a very popular technique, but now it is a very powerful and enigmatic, that it has the potential to maintain hope, offering the surgeons a change to carry out the operations which would have been impossible without it.

    Lance Becker, founder and director of the center for Resuscitation Sciences at the University of Pennsylvania Hospital in Philadelphia, is an internationally recognized leader in the field of reanimation, cardiac arrest and intensive care; he focuses on studying acute reanimation of terminally ill, agonizing or critically ill patients. The laboratory of the Feinstein Institute where he works, he has the experience in the measurement of mitochondrial dysfunction, oxygen and nitrogen reactions. His goal is to develop an emergency cardiopulmonary bypass system with advanced life saving drugs for patients who fail the traditional advanced cardiovascular life management system to revive and bring them to life.

    With the procedures that Lance has had to perform, the mitochondrial research has been his greatest help for many experiments, since it provides cellular respiration and supplies energy to the cell, and takes all the food that the body ingests and the oxygen that it breathes, to convert it into a chemical energy that gives life and stability to the patient. All in order to demonstrate that there is subsistence after death using resources to help people and give them a better quality of life. On the other hand, it is stipulated that the human cloning process could solve a great number of medical problems bringing them back to life, but no scientific research has endowed it, as it takes years of studies and tests to develop them.

    Cloning has helped to gain identical laboratory animals, more resistant plants, or even prevent the extinction of some species through the reproductive system, which allows the creation of a new human being, containing the same genome as the one of the cell donor. When you clone, you need to have a living cell, but the result will never be as expected, it tries to keep its same traits and physically looks the same but it will never become an exact clone to the donor. With the realization of these investigations, it has become evident that there is life after death, that with the passing of time the studies are yielding unexpected results that create significant changes in the human beings or even give them another opportunity in life. Is it possible that this experiment can be done on any human being alive or dead and that it will yield success with it for the future?
