Recycling helium is under discussion, but it is not actively used yet. Like with many other materials, there are two ways to obtain helium: either extract it from nature or synthesize it in a laboratory. Helium can only be extracted, since synthesis costs too much. It also has the highest thermal conductivity – its ability to carry heat away – of any gas except hydrogen. Its boiling and freezing points are lower than those of any other known substances. It is a noble gas, meaning that it does not chemically react with any other substance. Helium is the second-smallest atom in nature, behind only hydrogen. Others are not so obvious and may be used behind the scenes in a way that does not incorporate them into the chip. Helium is one of the latter, being used, among other things, for cooling. Some of them, like silicon, are obvious and end up in the final product. The making of a semiconductor chip involves a wide variety of materials. As a result of supply concerns, many companies, including Lam, are looking for ways to reduce their helium usage. Helium gas is increasingly in short supply. While consumers may be most familiar with it for use in filling balloons, it is used much more heavily in a variety of industrial processes – including semiconductor fabrication.

Other investigators have proposed novel therapeutic strategies including some based on the molecular and genetic phenotype of the disease. There are numerous investigators around the world who have made seminal discoveries about the important molecular pathways and genetic alterations that contribute to the development and metastases of osteosarcoma. In order to improve the outcome of this disease, the biology of osteosarcoma needs to be better understood. The lungs are the most common site of metastases and once osteosarcoma spreads to the lungs, it is very difficult to treat.

Osteosarcoma accounts for approximately 56% of new bone tumors, making it the most primary malignant bone tumor in children and adolescents. Osteosarcoma is an aggressive malignant neoplasm and is the most common histological form of bone cancer. Current Advances in Osteosarcoma summarizes molecular and genetic characteristics, new therapeutic ideas, and biological characteristics that have been uncovered in this field over the past 10 years.
