Researchers in the US and UK say they have invented a new microscopy technique for imaging live tissue with unprecedented speed and resolution. The technique involves using the tiny tip of an atomic force microscope to tap on a living cell and analysing the resulting vibrations to reveal the mechanical properties of cell tissue. The team says that the technique could have widespread applications in medicine. However, another expert in the field suggests that the group has not demonstrated the superiority of the technique to those already available.
This is an idependent organisation reviewing healthcare studies and basically judging the results. Something like the ACT for international medicine. Sounds interesting in the approach. Their suggestion for swine-flu prevention: wash your hands frequently. Nothing helps better.
By reactivating a dormant gene called Lin28a, which is active in embryonic stem cells, researchers were able to regrow hair and repair cartilage, bone, skin and other soft tissues in a mouse model.
"Cardiologists had been so focused on immediately measurable arrhythmias that they had overlooked the longer-term but far more important variable of death."
lol
The picture was made with the Canon 5D mark II and a 400mm-lens. It consists of 1.665 full format pictures with 21.4 megapixel, which was recorded by a photo-robot in 172 minutes.
"With a resolution of 297.500 x 87.500 pixel (26 gigapixel) the picture is the largest in the world. (stand December 2009)"
Daring statement... I'm not quite sure, but I'd quess microscopic images used in medicine can easily reach terapixels...
What a waste of pixels anyway... they weren't able to find a bit more interesing city?
A group of proteins that act as the body's built-in line of defense against invading bacteria use a molecular trick to induce bacteria to destroy themselves...
DRACO selectively induces apoptosis, or cell suicide, in cells containing any viral dsRNA, rapidly killing infected cells without harming uninfected cells. As a result, DRACO should be effective against virtually all viruses,
Holy grail of medicine... if this indeed works and is safe (which I actually doubt), someone's going to make a nice fortune.
BTW the toupee of the guy on the photo says it all :)
Eve, an artificially-intelligent 'robot scientist' could make drug discovery faster and much cheaper, say researchers writing in the Royal Society journal Interface. The team has demonstrated the success of the approach as Eve discovered that a compound shown to have anti-cancer properties might also be used in the fight against malaria.
