1. Researchers in Japan have developed a plastic that dissolves in seawater within hours, offering up a potential solution for a modern-day scourge polluting oceans and harming wildlife. While scientists have long experimented with biodegradable plastics, researchers from the RIKEN Center for Emergent Matter Science and the University of Tokyo say their new material breaks down much more quickly and leaves no residual trace. At a lab in Wako city near Tokyo, the team demonstrated a small piece of plastic vanishing in a container of salt water after it was stirred up for about an hour. While the team has not yet detailed any plans for commercialization, project lead Takuzo Aida said their research has attracted significant interest, including from those in the packaging sector. Scientists worldwide are racing to develop innovative solutions to the growing plastic waste crisis, an effort championed by awareness campaigns such as World Environment Day taking place on June 5. Plastic pollution is set to triple by 2040, the UN Environment Program has predicted, adding 23-37 million metric tons of waste into the world's oceans each year. (Sources: riken.jp, reuters.com)

2. People are more likely to get cancer as they age. Dr. Miriam Merad has an unconventional idea of how that might be reversed: using allergy drugs and other seemingly unlikely medications to damp a condition known as “inflammaging.” The immunologist and oncologist has spent years examining malignant tumors to learn why people over age 50 account for nine in 10 cancer diagnoses in the U.S. She and her research team at the Icahn School of Medicine at Mount Sinai in New York City have homed in on an answer: the aging immune system. Their studies of individual immune cells in human lung tumors, as well as in old mice, have revealed how chronic, or pathogenic, inflammation in older people—dubbed inflammaging—interferes with the immune system and fuels cancer growth. Merad and other researchers are testing whether existing anti-inflammatory medications usually used to fight rheumatoid arthritis or allergy conditions like asthma or eczema can slow cancer in older patients. They are also searching for new drugs. “Aging is something that we think we can transform,” says Merad, director of the Marc and Jennifer Lipschultz Precision Immunology Institute at Mount Sinai.
