• Migraines May Be Caused by Vascular Reactivity

  …t only vascular tone, but also more complex metabolic and neuro-regulatory processes within vessels. Increased vascular reactivity is most commonly observed in spasms of the arteries and less – in their extension. Every blood vessel binds with the nervous system, which controls its contraction. The nervous system harmoniously transmits the pulsations throughout th…

• Lenticular Images: Researchers Combine Art & Science

  …d, and a smartphone or a tablet to control movements of the camera. Before that we determined the shooting parameters and required number of photos, which depends on the characteristics of the ribbed surface of the lens used to make images three-dimensional.  Making only 25 photos was enough to construct a lenticular image. And the next step was UV printing," comment…

• Optics Used for Measuring Blood Velocity

  …y "Information Science and Semantic Technologies" explained that the most widespread method to measuring blood velocity is using doppler ultrasound to assess it in the large arteries, - something similar to how radar guns work. Still, sometimes knowing the blood velocity in the large arteries is not enough: a great deal of blood goes th…

• Scientists Count Microscopic Particles Without Microscope

  …, bring them into focus, rotate and change their type of motion. Ordinary lenses cannot cope with these tasks at nanoscale, so scientists are working with artificial optical materials – photonic crystals and metamaterials, which can control the propagation of light in most extraordinary ways. However, fabricating optical ma

  … of the professors are from foreign universities, though there are also some Russian scientists as well. My Master's program in "Software Development" uses licensed learning materials from the Carnegie Mellon University (USA). All of the academic staff for the program were certified by this university, or are from it. I've talked to the students from last year, and t…

• Researchers Are on the Way to Obtain First Chemically Synthesized Metamaterial

  …According to the paper published in Dalton Transactions, the new material belongs to the class of Metal-Organic Frameworks (MOF) and has a crystalline structure comprising of iron clusters linked by organic ligands. The most apparent property of the resulting material is its giant porosity, which provides numerous active centers inside …
