A CT scan takes pictures of the inside of the body. The pictures are more detailed than a typical x-ray. During a CT scan of the chest pictures are taken of cross sections or slices of the thoracic structures in your body. The thoracic structures include your lungs, heart and the bones around these areas.

Open a can of mixed nuts, and chances are you'll find a bunch of Brazil nuts topping the heap—whether that's a good or bad thing depends on how you feel about Brazil nuts. It's such a common phenomenon that it's known as the "Brazil nut effect" though muesli mix also gives rise to the same dynamics of granular convection. Now, on video for the first time, a team of scientists from the University of Manchester in England has captured the complicated dynamics that cause the Brazil nut effect, according to a new paper published in the journal Scientific Reports. From a physics standpoint, those mixed nuts are an example of a granular material, like a sand pile. As I wrote at Gizmodo back in , the primary mechanisms behind the Brazil nut effect are percolation and convection. Percolation causes smaller grains to move through larger grains to the bottom of the pile, while convection pushes the larger grains toward the top.

Giving smokers and ex-smokers a CT scan uncovers cancerous lung tumours when they are at an early enough stage so they can still be removed, rather than continuing to grow unnoticed, it shows. Experts are demanding the government moves to bring in routine CT scanning of smokers and ex-smokers in order to cut the huge death toll from lung cancer. About 48, people a year are diagnosed with the disease in the UK and 35, die from it — 96 a day. Lung cancer is a particularly brutal form of cancer because it is hard to detect and three out of four cases are diagnosed at stage three or four, when it is already too late to give the person potentially life-saving treatment. However, the Summit study , being run by specialists in the disease at University College London Hospital NHS trust, offers real hope that lung cancer can become a condition that is detected early.
