Utilizando información de la etnomedicina (remedios caseros) y la farmacología antigua, Julius dilucidó lo que ocurre cuando nuestro cuerpo se topa con pimientos chiles. En 1997, Julius y sus colegas clonaron y caracterizaron el receptor potencial transitorio V1 (TRPV1), la molécula que detecta la capsaicina, la sustancia química que hace “picantes” a los pimientos chiles. Descubrieron que el TRPV1 también detecta el calor nocivo (termocepción). El TRPV1 forma parte de una gran familia de canalesde cationes estructuralmente relacionados con potencial de receptor transitorio (TRP). Los animales que carecen de TRPV1 pierden la sensibilidad al calor nocivo y a la capsaicina. Puede parecer obvio, pero estos receptores no existen simplemente para…

Using information from folk medicine and old pharmacology, Julius elucidated what happens when our bodies encounter chili peppers. In 1997, Julius and his colleagues cloned and characterized the transient receptor potential V1 (TRPV1), the molecule that detects capsaicin, the chemical in chili peppers that makes them “hot.” They found that TRPV1 also detects noxious heat (thermoception). TRPV1 is part of a large family of structurally related transient receptor potential (TRP) cation channels. Animals lacking TRPV1 lose sensitivity to noxious heat and capsaicin. It may seem obvious, but these receptors don’t exist simply to allow us to enjoy Mexican food; they are responsible for a body function that allows us to…

Yes, if we are talking about a hanky. Cotton, linen, hemp, and so on are predominantly made of cellulose, a polymer that consists of thousands of glucose molecules joined together to form linear chains. Each glucose subunit is “sticky” because it can bind to neighboring cellulose molecules via hydrogen bonds. Individually, these bonds are very weak, but together they form a network that gives the fabric its strength. These hydrogen bonds break and reform, so clothes start taking on the shape that they are left, and creases form. When we apply a hot, steaming iron, the combination of heat and moisture breaks the hydrogen bonds, and with the pressure applied…

As a skin care company, do we need to be cute to be successful? It is too late to change our name, Skin Actives Scientific to something cute like “troll skin” or “sweet minuet”. Philosophy is already taken. What should matter to our customers is whether there are ingredients in other brands that we should envy. Trust me: this does not happen often because we are so cutting edge.We know what works, we are up-to-date with scientific literature and we can find or make anything that is worth gaving. Specifically, do I envy any ingredient in Drunk Elephant? Because if I envied a cute little fridge or a fancy container,…

Rosacea is a chronic skin disorder that affects more than ten million Americans, with almost half of the sufferers aged between 30 and 50 years old. The disease has been called “the Celtic curse” because it affects people of Northern European descent more often. Women are more likely to suffer rosacea of the milder form, and men more frequently have the severe form, which involves deformity of the nose. Rosacea nearly always appears on sun damaged skin.
