By José Ramón Alonso

Whiskers or vibrissae are a type of mammalian hair characterized, anatomically, by their larger, thicker and stiffer morphology, large and well-innervated hair follicle and by having a definite projection in the somatosensory cortex of the brain, forming the so-called “barrels”. The ‘barrels’ of the barrel field are regions within cortical layer IV that are visibly […]

A chemical compound or molecule consisting of two identical simpler molecules is a dimer. If one of the simpler molecules is excited while the other is in its ground, non-excited, state we talk about excimers. They are excited dimers which are non-bonding in the ground state. Thus, excimers can be considered evanescent quasi-particles that typically […]

Parasite plant check

Plant biology

By José Ramón Alonso

Cuscuta (dodder) is a genus of about 200 species of obligate parasitic plants. They use airborne volatile organic compound cues to locate their host plants and then, they produce feeding structures named haustoria that penetrate into the vascular system of the host plants and suck their sap exploiting their carbohydrates, nutrients, and water. They also […]
