A cause of possible genetic problems in mitochondria is revealed
(University of Seville) The loss of mitochondrial information and of mitochondria gives rise to defective cell metabolism. As well as the lack of capacity to generate the energy necessary for the cells, the loss of mitochondrial information can generate an increase in oxygen free radicals that attack and damage the genetic material or produce Iron-Sulphur protein deficiencies. All this brings about incorrect cell functioning and eventually cell death. (Source: EurekAlert! - Biology)

A stunning image released by NASA shows what Kilauea, the volcano in Hawaii that has been erupting for three weeks, looks like from space. As the photo shows, Kilauea is not only visible from space — you can also see the lava spewing out of the volcano. Seven instruments aboard NASA ‘s International Space Station and partner satellites have been detecting active fissures, fires, ash and sulphur dioxide plume as well as the height and composition of volcanic plumes, a NASA release explains. “One of the first things emergency responders wanted to know was where the lava was coming out, where are all the fis...

Maybe the healthiest wine in the world
When I was in South Africa last year, I met a revolutionary winemaker… His wine was completely organic. It had no toxins, and it contained powerful antioxidant properties. It was infused with a local herb called rooibos, also known as “red bush.” You may have seen rooibos tea on supermarket shelves. I immediately knew this wine should be made widely available in America — and I’m still hopeful a distributor will bring it here. I enjoy a nice glass of red wine from time to time, but the trouble with most of the wines sold in America is that they’re loaded with dangerous chemicals. Winema...

Sarcomatoid is the least common of the three mesothelioma cell types but is considered more aggressive and harder to treat.

Conclusion This study showed a clear link between rises in gas and particle pollution and the chances of being admitted to hospital or dying because of a stroke. The researchers showed the link was strongest on the day of exposure to raised pollution levels. But this study has some limitations. While systematic reviews are a good way to summarise all the research that has been published on a topic, they are only as good as the individual studies they include. About two-thirds of the studies used a time series design, which the researchers say is less effective in taking account of trends such as the season of year, rathe...

Preservation of wine without sulphite addition
A good glass of wine is a byword for quality of life -- and not just for connoisseurs. In order to avoid wine spoilage, wineries mostly add sulphur dioxide during the winemaking process. However, the sulphites that dissolve in wine can cause allergic reactions – including asthma. Within the EU they must therefore be declared as an ingredient on the label and the limits for sulphites in wine have been reduced. Sulphites unfold their preservative action in two ways.
