10 recent advances in science, refers to the future
Scientific discoveries are happening every day and change the world in which we live. In this list, there are some crazy scientific innovation, and they were all made in the past year. Technological and medical discoveries, in which people just can not believe accomplishes every day and still accomplishes with enviable regularity. These discoveries bring with them a host of new technologies and methods that will only grow and improve over time.
Ability to control the movement of the subject – it’s something out of science fiction, but thanks to researchers from the College of Science and Technology of Minnesota, it became a reality. Using a non-invasive technique known as electroencephalography, the specter brainwaves, five students were able to control the movement of the helicopter.
Looking at the opposite side of the helicopter, the students were able to move trucks in different directions, mimicking the motion of the left hand, right hand and both hands. After some time, the project participants were able to perform several maneuvers the helicopter, including passage through the ring. Scientists hope to improve this non-invasive brain waves control technology that will ultimately help restore movement, hearing and vision in patients suffering from paralysis or neurodegenerative disorders.
MRI of the heart
Anthracycline is an effective form of chemotherapy, but it is proved that it could harm the hearts of children undergoing treatment. As a rule, the majority of children affected by this heart defect, it was found that the walls thinned their hearts, and by the time the diagnosis was already too late to do something. Ultrasound often miss heart disease in the early stages of research and finds them only when irreversible damage has already taken its toll.
In the last year, a fundamentally new technology. During extensive testing revealed that T1 MRI may be more precise, effective and safe method to detect cardiovascular disease in children. Doctors were able to see children’s heart diseases earlier and more efficiently than with ultrasound (erroneously indicate that the heart feels fine). This is a great medical progress to detect heart disease in young children.
Effective electrolysis (salt water splitting)
In the race to find an effective and rich alternative fuels, researchers are constantly trying to find a way to effectively splitting sea water to produce hydrogen fuel. In June last year, the Australian team of electrical science research center published a catalyst which is able to cleave the oceanic water is not being used a lot of energy.
The catalyst was embodied in flexible plastic tank which absorbs and uses the energy obtained from light, for the oxidation of the seawater. Unlike existing methods, which require large amounts of energy for the oxidation of water, this method can produce enough energy to power the average home and a car for the whole day, using only 5 liters of seawater.
This tank contains the synthetic chlorophyll molecules using solar energy, just as do plants and algae. Chemical problems in this method either, unlike the current method of splitting water, during which emitted a cloud of poisonous gas – chlorine.
This efficient and effective method can significantly reduce the cost of hydrogen fuel that will allow him to become a competitive alternative to gasoline fuel in the future.
With the invention of 3D-printers limits for types of complicated and complex objects that you can create a substantially widened. Last year, a team of researchers from Harvard and the University of Illinois have been able to synthesize lithium-ion battery, which is less than a grain of sand and finer than a human hair.
Equally striking sizes achieved using thin layers of interwoven network of electrodes. Once the computer has been made 3D-design, the printer use specially made liquid inks containing electrodes that had immediately harden, getting on the air. Such a device can find a lot of applications, thanks to its size. However, in the 3D-printers already print the circulatory system of blood vessels, so few people are surprised electrodes.
Before this battery life is incredibly small objects battery power was impossible. The fact that the creation of such batteries needed such batteries that can transmit the first energy. 3D-printer uses ink and detailed design of a computer program, creating similar mikrobatareyki.
Bioengineered body parts
June 6, 2013 a group of doctors at Duke University successfully implanted the first bioengineering blood vessel living patient. Although bioengineering developing by leaps and bounds, this procedure has become the first successful implantation of an artificial body parts bioengineering.
Vienna was implanted to a patient suffering from end-stage renal disease. First, it was synthesized from human donor cells to a sort of “forests”. To prevent any foreign body wave antibodies in the patient from the vein removed qualities that could provoke the attack. And the vessel was more successful than synthetic implants or animal origin, because he was not inclined to clot and did not represent a risk of infection during surgery.
Unbelievable, but the veins are made of the same flexible material that connect them, as well as take on the properties of the cellular environment and other veins. With the success of this procedure, this new field has huge implications for the future development in the world of medicine. In addition, in 10-15 years will be printed bioengineering heart, according to forecasts.
Search explain the birth of our universe was warmed significantly since last year’s announcement of the discovery of the four-quark particles. While you will find this may not seem too important for physicists it raises a number of new explanations and theories about the creation of the first matter. Until the moment of creation of matter explanation was severely limited by the fact that only particles were found with two or three quarks.
Scientists named the new particle Zc (3900), and they suggest that it was created in the first furiously hot second after the Big Bang. After several years of complex mathematical calculations carried BaBar collaboration to accelerate National Laboratory SLAC (affiliated with Stanford University), scientists working at the Beijing electron positron collider (BEPCII) found that particle on a number of occasions. Because scientists are generally quite generous people shared the results with the guys and CERN HEARO in Tsukuba, Japan. These are the same scientists who have recently seen and identified 159 such particles. However particle lacked justification, while scientists with Belle detector in Beijing have not confirmed the allocation of 307 individual particles of this type.
Scientists claim that took hold 10 trillion trillion subatomic collisions in their detector, which is twice more than the famous Large Hadron Collider in Switzerland. Some physicists have criticized the observations, claiming that the particle is not more than two mesons (two quark particles) connected together. Despite this, the particle was adopted.
Alternative microbial fuel
Imagine a world in which a high-performance, low-cost alternative fuel could be obtained as easily as oxygen from the air around us. Thanks to the collaboration of the Ministry of Energy of the United States and a team of researchers at Duke University, we may have germs that dream a reality. In recent years there has been more success in the world of alternative fuels (such as ethanol from corn and sugar cane). Unfortunately, these methods are very inefficient and can not withstand criticism. Not long ago, scientists have been able to come up with elektrotoplivo that can “eat” the solar energy without taking from us water, food or land, like most alternative fuels.
In addition to low energy requirements, tiny microbes can effectively synthesize it in the laboratory elektrotoplivo. Elektrotoplivnye microbes were isolated and found in non-photosynthetic bacteria. They use electrons in the soil in the form of food and consume energy to produce butanol, interacting with electricity and carbon dioxide. Using this information and performing some manipulation of genes, the scientists involved in this type of bacteria grown in laboratory cultures of bacteria, allowing them to produce butanol in huge quantities. Butanol now looks like a better alternative to ethanol and gasoline for many reasons. Being a larger molecule, butanol has a great potential for storing energy than ethanol and does not absorb water, so it may be in the gas tanks of any vehicle and transmitted through gasoline pipelines. Butanol microbes become a beacon promising era of alternative fuels.
Medical benefits of silver
Research on the benefits of using silver antibiotics was published on June 19 last year, researchers at Boston University. While it has long been known that silver has the strong antibacterial properties, researchers have only recently discovered that it can be converted into conventional antibiotics antibiotics steroids.
It is now known that silver uses many chemical processes to prevent the growth of bacteria, slow down their metabolism and disturb homeostasis. These processes lead to a weakening of bacteria and render them more susceptible to antibiotics. Many studies have shown that a mixture of silver and antibiotics was up to 1000 times more effective in killing bacteria than just antibiotics.
Some critics warn that silver may have toxic effects on the patients, but scientists do not agree with this, arguing that small amounts of silver and non-toxic only increase the effectiveness of antibiotics without damaging the treatment. This is a very interesting discovery for the medical world, and the use of precious metals continues to grow in quantity and quality.
Sight for the Blind
The first prototype bionic eye was presented bioengineers Australian team in early June last year. Bionic eye works by using a chip implanted in the skull of the user, and then connected to a digital camera in the glasses. While glasses now allow the user to only see the outlines of the prototype must be significantly improved in the future. Once the camera captures the image signal is changed and sent wirelessly to a microchip. From there, the signal activates the point on a microchip implanted in the cortex of the brain responsible for vision. A team of researchers hopes that in the future lightweight, comfortable and unobtrusive glasses can provide maximum comfort to people with poor eyesight. They can be used 85% of blind people.
Immunity to cancer
Last year, the University of Rochester published a study , which examined the mechanism of confrontation cancer in naked mole rats. These eerie underground rodents not the prettiest on the planet, but they will have the last laugh when all living things will die from cancer.
In the spaces between the cells bodies of naked mole rats was found sticky sugar, hyaluronan (HA), and he seems to close the widening prevents cells and the formation of tumors. Roughly speaking, the substance stops reproduction of cells once they reach a predetermined density. The reason for the increased amount of sugar is how scientists think, a double mutation in two enzymes that promote the growth of HA.
It was found that the cell with low HA rapidly growing cancer, but cells with highest level of tumor HA is not formed. Scientists hope to modify laboratory rats to produce large amounts of HA and they develop immunity to cancer.
