Skin transformed for cancer fight

Dynamic sites reviled us that scientists are working tirelessly to open new possibilities that one day Cancer Patients will be using their own skin cells to fight their tumours.

This study was published in the famous journal Gene Therapy and was focused on dendritic cells and their unique properties, which are responsible to organised a part of their immune response. By showing identifying antigens or markers cells tell the immune system what and where to attack. If they can display cancer markers then obviously the cancerous cells will become the targets.

Experiments conducted in various laboratory showed that these dendritic cells were able to activate both kind of cells, namely those which kill foreign cells and those produce anti bodies.

"Now the very next challenge is to confirm out if these laboratory-generated cells will be competent enough for immunotherapy-based cancer-treatments to be used in the clinic."

Solar flares, coronal mass ejections (CMEs)

Solar flares are like large explosions found on sun that send light, energy and high speed particles into space. These flares are found associated with large solar magnetic storms that are known as (CMEs) coronal mass ejections. The number of such flares usually increases in every 11 years, and currently sun is moving towards another, that is likely to be in 2013. This means that more of the flares will be coming in the times to come, some may be small and some may be big enough to send their harmful  radiation to the Earth.

If these will be directed at Earth, such CMEs and the associated flares will result in very long lasting radiating storms that will harm communication system, power grids, satellite systems, and various land-based technologies. For example,: X-class flares occured on 5th Dec, 2006 and 6th Dec, 2006, triggered the CME that had badly interfered with the GPS signals which used to be forworded to land-based signal receivers.
