Researchers at the University of Waterloo have developed a lightweight, flexible polymer material that could replace lead in X-ray aprons while providing comparable protection from harmful radiation. By incorporating specially engineered tungsten nanoparticles into a silicone-based nanocomposite, the team created a shielding material that is nearly 90 per cent lighter than traditional lead aprons, potentially reducing the back and neck injuries commonly experienced by health-care workers who wear them for extended periods.

Marine wildlife trafficking is big business, raking in billions of dollars every year and threatening species’ survival and the health of ecosystems. But trafficked sea creatures are often concealed in ordinary travelers’ luggage or packages, which makes it hard to spot and seize illicit shipments. Now scientists have used a neural network, a form of AI, to teach an algorithm to spot three commonly trafficked products — shark fins, sea cucumbers, and dried seahorses — in CT scans of bags like those taken at airports. The algorithm, which had a 92% success rate in testing, could help detect marine wildlife trafficking at scale and stop the trade in progress.

As the United States approaches its 250th anniversary amid deep political division, a major new bipartisan report from the State of the Nation Project asks a fundamental question: How are we really doing as a country? The first-of-its-kind State of the States report analyzes more than three decades of data and 4,000 indicators across all 50 states and Washington, D.C., ranking states on 31 measures of well-being, trust, education, health, inequality, the economy and more. The findings point to an increasingly unhappy nation: Despite sharp political divides, red and blue states are facing many of the same struggles, including worsening mental health, declining trust, rising social isolation and falling life satisfaction. No state is improving on eight key measures, including life satisfaction, adult and youth depression, fatal overdoses, trust in the federal government, income inequality, long-term unemployment and hourly earnings growth.

A new pharmaceutical production method could allow astronauts on long space missions to "grow" fresh medicines on demand using plants. The work could also bring low-cost pharmaceutical production to resource-limited areas on Earth.
