“What is Horvath’s/Epigenetic Clock? Understanding the first-ever accurate Age Predictor…” Greying hair and wrinkles are external signs of ageing, but they are not very precise. Now research shows that a code written into the body's epigenome — the chemical tags that modify DNA — can accurately tell the age of human tissues and cells. This ‘clock’ innovated by Steve Horvath could provide insights into why certain tissues age faster than others, and why those tissues may be more cancer-prone. In the past few years, researchers have been homing in on regions of DNA that accrue lots of chemical tags called methyl groups as people age. Such methylation can selectively switch off ...
This book covers advances made since the 2004 Springer volume “Polarized Light in Animal Vision” edited by Horvath and Varju, but also provides reviews and synopses of some areas. Part I examines polarization sensitivity across many animal taxa including vertebrates and invertebrates and details both terrestrial and aquatic life. Part II is devoted to the description of polarized light in nature and explores how the physics of light must be taken into account when understanding how polarized light is detected by the visual system. This includes underwater polarization due to scattering; polarization patterns reflected from freshwater bodies; polarization characteristics of forest canopie...

Rapidly Quenched Metals 6, Volume 1 covers the proceedings of the Sixth International Conference on Rapidly Quenched Metals held at Le Centre Sheraton, Montreal, Canada from August 3 to 7, 1987. The said conference discusses a wide variety of topics in the field of rapidly solidified metals. The book is divided into two parts. Part 1 covers topics that involve the formation and transformation in metallic materials; amorphous metals; the applications of mechanical alloying; and rapid melting and quenching. Part 2 discusses the formation and structure of amorphous alloys, which includes topics such as the metastability of amorphous phases; amorphous alloy powders; and studies about the properties of different amorphous alloys. The text is recommended for those involved in materials science and metallurgy, especially those studying rapidly solidified metals and amorphous alloys.
This Atlas is a unique scientific publication. It includes major issues of up-to-date information about immunophenotype, morphology and the function of the main effectors of anti-tumor immunity set down in a well presented format. The Atlas comprises a large number of illustrations presenting schemes and original micrographs demonstrating morphological features and ultrastructure of immunocompetent cells at various stages of differentiation. A special section of the Atlas describes cellular tumor microenvironment and micro-anatomy of carcinomas. Several parts include data about killer cells and T-regulatory lymphocytes.
