Can you imagine a world where fertilizer production is thoroughly sustainable and recycled, thus enabling global food access that meets population growth? Where waste considered resource has value; buildings monitor air water to keep us safe; pathogen-destroying coatings are integrated into fabrics clothing; sensors noninvasive, continuously monitoring our health while personalizing advancing m...

We calculate the finite temperature self-energy for neutrinos in the presence of a constant magnetic field in a medium in the unbroken SU(2) ⊗ U(1) model. We obtain the exact dispersion relation for such neutrinos and find that the thermal effective mass is modified by the magnetic field. We also find a simple analytic expression for the dispersion relation and obtain the index of refraction fo...

Our aim is to develop a versatile toolset for constructive learning. We achieve it through the marriage of powerful learning tools: a universal learning environment Imagine Logo (Kalaš and Hrušecká, 2004) and the recent and most popular educational robotics kit LEGO Mindstorms NXT. LEGO Mindstorms NXT is the second generation robotics toolkit. Performance and robustness have been improved, infr...

Svante Pääbo works on the edge of what’s possible. He ignites our imagination, unlocking tightly held secrets in ancient remains. By patiently and meticulously working out techniques to extract genetic information from skin, teeth, bones, and excrement, Pääbo has become the leader of the ancient DNA pack. Sloths, cave bears, moas, wooly mammoths, extinct bees, and Neanderthals— all have succumb...

An individual’s life or his/her entire medical history, from conception to death, may be documented as ultrasound images, radiographies, tomographies, photos, movies of surgical procedures, and measurable data converted into graphics illustrating descriptive and comparative statistics. Could anyone have predicted this 20 years ago? This is possible and not only limited to ophthalmology. Most, i...

Background: The dengue and chikungunya epidemics have major challenging problems and have become essentially a public health importance in India for the recent years, and it has been transmitted by the Aedes genus (Aedes aegypti or Ae. Albopictus) mosquito vectors. The huge chikungunya epidemic cases was reported in 213 districts especially in South India during 2006 and it happened in India, a...
