Nanoparticle that can stop multiple sclerosis

Image
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. ...

What's inside a CT Scanner

Image
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. 

Genetics and Heredity - Lookalikes

Image
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 ...

Work out could improve the quality of sperm

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...

Impressive translation technology developed by Microsoft

Image
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...
