Roundup of Health stories: Eggs, malaria, organic food, rosacea, your internal brush and zapping blood pressure

Sunny-side up  In Defense of Eggs

Recent research on the dangers of egg consumption is misleading and unnecessarily alarming. The dangers of cholesterol are over-hyped, and we can't underestimate the value of unprocessed, high-mineral foods.

Most people should be eating more eggs, particularly the yolks.

Great news.  Scientists close to creating single-dose cure for all strains of malaria.

New treatment should enter clinical trials in 2013
Malaria killed 655,000 people in 2010.

Organic no better than produce grown with pesticides, say Stanford University scientists.  Biggest study yet.

Red skin condition rosacea could be caused by mite feces in your pores.  Yuk

Internal 'brush' that lines the lungs could offer insight into treating diseases such as cystic fibrosis and asthma

Brush-like layer pushes out sticky mucus and the unwanted matter it contains
-
The researchers used imaging techniques to examine what was actually happening within the lungs - and found a dense meshwork of human bronchial epithelial cell cultures. The brush-like layer consists of protective molecules that keep sticky mucus from reaching the cilia and epithelial cells, thus ensuring the normal flow of mucus.

Dr Michael Rubinstein, who led the study, said: 'The air we breathe isn't exactly clean, and we take in many dangerous elements with every breath. 'We need a mechanism to remove all the junk we breathe in, and the way it's done is with a very sticky gel, called mucus, that catches these particles and removes them with the help of tiny cilia.'  'The cilia are constantly beating, even while we sleep.  'In a co-ordinated fashion, they push mucus, containing foreign objects, out of the lungs, and we either swallow it or spit it out.

It is hoped the findings will help scientists understand more about lung diseases such as asthma
