What Really Causes Acne
Many people blame hormones and natural body oils for causing acne. In fact, it's much more complicated than that. Acne is caused by a combination of clogged pores, bacteria, hormones, and an aggressive immune system.
You probably know that your skin is covered with tiny openings called hair follicles, or pores. Attached to each pore are glands that produce a natural oil called sebum. The pores are lined with specialized skin cells called keratinocytes. These cells have a limited life span and eventually slough off after they die. Usually they're flushed out by the sebum and get rinsed off the next time you take a shower. However, sometimes these follicular cells react abnormally to the hormones your body produces, mostly male hormones called androgens. Men and women naturally produce androgens from the time they it puberty, which is why children usually aren't plagued with acne until they become teenagers.
The cells in your pores react to these hormones by becoming thick and sticky. The sticky dead cells form a plug that blocks the pore, trapping the sebum oil. Initially this results in noninflammatory acne, otherwise known as whiteheads and blackheads.
Tender red acne forms mostly as a result of a bacterium called P. acnes. This bacterium thrives in dark, warm, oily places where it's exposed to little oxygen--which perfectly describes your pores! But the problem really begins with your immune system, which sees P. acne as a serious threat and launches a full-scale attack. P. acne is pretty harmless, so this response is a bit like using dynamite to kill a mouse. This causes the acne to become even more sensitive, inflamed, and prone to scarring.
Although diet, stress, and other factors may not be a direct cause of acne, many experts now agree that they definitely play a role. For example, recent studies confirmed that stress can increase the production of androgen hormones, which in turn encourages keratocyne cells to clump together and plug your pores.
Unfortunately, there is no cure for acne. However, it can be controlled. By keeping track of your acne triggers and using an appropriate skin regimen, you'll rid yourself of those annoying pimples and enjoy clear skin again becoming Acne Free.

Mapping Asthma - GPS in Clinical and Preventive Medicine
The Spiroscout inhaler tracker on Asthmapolis.
By tracking the use of inhalers, Asthmapolis aims to help patients and physicians improve management of asthma and provide a valuable new source of aggregated, anonymous and voluntarily shared data for scientists and public health.

Online Collaboration in Proteomic Research
EpiC (The Epitope Choice Resource) aims to provide physio chemical predictions of antigenicity together with functional annotation in order to provide the user with adequate information in order to make a decision about the best location of an epitope for an antibody based experiment. The project connects to a wide range of servers throughout Europe and was funded by the EU Framework 6 networking action ProteomeBinders.
