Did you know that cancers in the head and neck area, including the mouth, throat, nasal cavity and voice box, account for about 4% of all new cancers diagnosed in U.S. each year? Major risk factors include smoking cigarettes as well as the use of smokeless tobacco (chewing tobacco and vaping) and alcohol. People with the human papilloma virus (HPV) are also at higher risk of developing head and neck cancer. Symptoms of the disease include a lump or sore in the mouth that doesn’t go away, difficulty swallowing and swelling of the chin or around the jawbone. Although there is no standard screening for head and neck cancers, dentists usually check the mouth for signs of cancer during routine appointments. The Alliance for Clinical Trials in Oncology and the Alliance Foundation Trials have several active trials specifically poised to help people with head and neck cancers.
Researchers have created heart monitoring sensors that conform to the skin, are comfortable, and can be worn while people are moving. With performance comparable to sensors already on the market, the new technology can be made using existing manufacturing processes.
A University of Texas at Arlington researcher is leading a new study that investigates cardio-sarcopenia—the combined loss of heart and muscle health in aging adults.
Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein’s theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum physics, this relativistic form of time becomes even more counterintuitive. According to quantum theory, the flow of time itself may exist in a genuine quantum superposition, ticking faster and slower at the same time. A new paper by physicists at Stevens Institute of Technology shows that this striking possibility may soon be tested in real life.
