Optical brighteners are a valuable component for bioinsecticide formulae based on baculovirus. These substances enhance their insecticidal capacity at the same time as they do not favour the development of resistance of the insects to these viruses, nor do they increase the probability that the insect might develop sublethal infections, rather than lethal ones. This is the conclusion of the Mexican engineer, Ana Mabel Martínez Castillo, in her thesis defended in the Public University of Navarre.
Plagues that effect maize
Baculovirus are a group of virus pathogens, specific to arthropods, that are currently used as bioinsecticides in various countries in the world. Their use on the land has shown that ultraviolet radiation from the sun is the main factor that affects the infectious capacity of the viral particles, provoking a drop in the efficacy of these bioinsecticides. For this reason, studies have been initiated in order to identify substances that, incorporated into the baculovirus formulae, enable an increase in its effectiveness and persistence.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
