A well-fitting respirator can reduce the risk. Credit: Shutterstock Silica dust is a very fine dust that is produced when products such as bricks, concrete and pavers are cut or drilled. Artificial stone, which is used primarily for kitchen countertops, is a very strong source of silica dust. Inhaling this dust into the lungs can cause severe long-term damage. This can lead to difficulty breathing, scarring of the lungs (silicosis) and lung cancer. In our recently published report, we estimate that without action, Australian workers will develop over 10,000 lung cancers in the future and nearly 104,000 cases of silicosis over their lifetime due to exposure to silica dust. This is about 1% of all future lung cancers in the Australian adult population. However, banning artificial stone would reduce silica exposure and could prevent 100 lung cancers and nearly 1,000 cases of silicosis over the lifet

Credit: Software Research Lab/UCLA UCLA materials scientists and colleagues at the non-profit scientific research institute SRI International have developed new materials and manufacturing processes to create artificial muscles that are stronger and more flexible than their biological counterparts. “Creating artificial muscles to allow work and detect force and touch has been one of the great challenges of science and engineering,” said Qibing Pei, professor of materials science and engineering at the UCLA Samueli School of Engineering and correspondent author of a recently published study in Science . For a soft material to be considered for use as an artificial muscle, it must be capable of generating mechanical energy and still be able to withstand high strain conditions—meaning that it does not easily

By Kalli Spencer After a radical prostatectomy there is always a risk that the cancer may recur. Certain factors can increase this risk such as high grade features in the initial biopsy specimen, cancer that may have emerged from the prostate capsule, micrometastases (cancer that cannot be detected by any imaging), technical difficulties in surgery or no explanation at all. in addition to the genetic makeup of cancer in a particular individual that gives it a predisposition to grow and invade. In its quest for survival, cancer develops several mechanisms to evade the immune system and may even counter the effects of treatment. The genetics behind this are still largely unknown. But scientists are studying it and success has been seen in other tumors such as colon and stomach cancer. A team from the University of Wisconsin in the United States has developed a unique diagnostic test that utilizes artificial intelligence to detect genetic disorders and determine which patients’ pros
