Men of science at Northwestern Medicine research center had a successful discovery in the field of nanotechnology and multiple sclerosis . They have discovered a perishable nanoparticle that seems to be the complete vehicle to stealthily bear an antigen that deceptions the immune system into discontinuing its aggression on myelin, and stop a model of reverting remitting disseminated multiple sclerosis (MS) in mice.   This discovery can be practiced to a diversity of immune-disorders like Type 1 diabetes, nutrient negative reactions and bronchial asthma. In multiple sclerosis , the immune system aggresses the myelin tissue layer that isolates nerves cells in the brain, optic nerve and spinal cord. When the layer is destroyed, the signals are having a hard time getting from one place to another, consequent in symptoms that chain from mild arm numbness to palsy or sightless. Almost 80% of multiple sclerosis patients have the getting worse postponing variant of the disease. ...

No, this is not a time machine! It's the inside of a CT Scanner. CT Scan means Computed Tomography scan, and some call it CAT (Computer Axial Tomography) . Mainly, it uses digital geometry to generate a 3D image of the inside of our bodies.  How it works The CT Scanner sends beams through the human body, while moving through an arc. 

Mom is blonde with green eyes, dad is dark-haired and has brown eyes. He has 1, 93m, she, on heels, is barely reaching his shoulder. Will their child inherit Mommy's genetics, or he/she will be a "carbon copy" of his Daddy?  Genetics - a lottery or a cocktail  There are so many possible combinations, that one couple can give birth to 70 billion different children. That, because every cell in the human body has 80,000 genes. In principle, half of these are given by the father, and half-mother.  And yet, these pictures say otherwise. Usually, a son or daughter has features of both parents. This is not the case here. The "dominant" gene was real strong in these cases, and it manifested clearly. Looking at these lookalikes, a single thought comes to mind: we are all copies of our parents.  Children will be smart like their parents?  Without a doubt, genetics acts like that! But if it's not stimulated since childhood, you can lose ...

The way we live may have a huge impact on our reproductive capabilities: it has been variably evoked that biking, wearing scrawny jeans,using drugs or using the laptop on your can affect the quality of sperm to some extent. The same speculations stated that healthy habits could improve the quality of sperm. Men of science at University of Cordoba have gathered the semen from 31 subjects. From those 31, 16 were physically active and 15 were sedentary. Also, scientists have tested their fitness levels in the lab. In order to get more accurate results, the subjects were asked to restrain from sexual activities before the tests.  Scientist have evaluated the samples, paying attention to volume, sperm count, motility, sperm morphology, color, odor, pH, vitality, viscosity. They have also analyzed the blood samples from every patient, looking for the levels of LH, testosterone and cortisol (a stress hormone).  The results demonstrated once more that physically active men h...

With this new technology developed by Microsoft, you will be able to speak fluent Chinese or Japanese, without knowing any Chinese word. This translation technology was developed by Microsoft and probably will be the next big thing in the following years.During a demonstration in Tianjin, head of research at Microsoft, Rick Rashid , showed how the new technology works. He proved that the system recognizes spoken phrases in English, and displays them on the screen. Moreover, it instantly translates them into Mandarin, and it also speaks them with the original voice of the speaker. This technology has been shown before in Sci-Fi movies, but it seems that this time is very close to a real-world implementation. Early research began 60 years ago, and so far, the best systems systems had an error rate of 20-25%. It seems that system created by Microsoft is much better. To develop this technology, Microsoft has collaborated with the University of Toronto, Canada. All research...

Scientists at Stanford University say they have managed to erase traumatic memories of mice while they were sleeping. The study aims to help people suffering from post-traumatic stress, says Nature. The standard treatment involves recollecting and talking about the painful events over and over again, in order to overcome this moment and learn to accept it.  In their study, scientists have induced this disease in mice. Every time they were exposed to jasmine scent, rodents were shocked. Then, half of the mice received the conventional treatment. While they were sleeping, they were exposed to the smell of jasmine, but not accompanied by the electric shocks. These mice, just like humans with post-traumatic stress, tended to regain the symptoms of the disease. The other group of animals was tested with an innovative technique. Researchers gave mice a drug to block production of a protein in an area of ​​the amygdala. That's a part of the brain associated with fear causing ...

For the first time, Scientists were able to observe a distant galaxy which was formed in the early days of the Universe, just 500 million years after the Big Bang. The discovery was possible thanks to the Hubble Space Telescope and the general relativity theory of Albert Einstein .  The oldest picture of the universe have been acquired by scientists using electromagnetic noise left from the Big Bang, a kind of diffuse halo that can not be associated with any star, galaxy or other astronomical object.  This occurs in less than 400,000 years after the Big Bang, a period that can be compared to a fraction of a second, according to the age of the universe (13.7 billion years). No star existed at that time, only the hydrogen atoms that were just created. It took another billion years to have another detailed image, but the landscape was already radically changed: the Universe was containing galaxies that included billions of stars.   What has happened in the ...
