A Hidden Source of Metal-Mining Emissions Could Be 10x Larger Than Estimated

The first comprehensive peer-reviewed academic assessment of CO2 emissions from neutralizing acid mine drainage in metal mining produced a startling result. Long after a metal mine stops operating, exposed minerals can continue reacting with water and releasing carbon dioxide for centuries or even millennia. Those emissions are rarely included in conventional mining carbon footprints, but […]

Plant Compounds in Berries, Tea, and Cocoa May Support Healthy Brain Aging

Polyphenol-rich foods may support healthy brain aging, but no single food or diet has been shown to prevent dementia. A cup of tea, a handful of berries, or a drizzle of extra virgin olive oil contains plant compounds that may influence processes tied to brain aging. A review by Semmelweis University researchers suggests that these […]

Scientists Find a Way To Keep Cancer-Fighting T Cells From Burning Out

A study suggests that exhausted T cells may be burning energy too aggressively rather than simply running out of it. Cancer immunotherapy can activate T cells, the immune system’s specialized killers, and direct them against tumors. Yet these cells often lose momentum before the cancer is controlled. Once they enter a state known as T […]

Scientists Discover Two Competing Memories in Matter

Physicists found that small particles suspended in a thick liquid can remember both the direction and strength of stirring, although one memory can erase the other. A folded sheet of paper still carries a crease after it is opened again. That mark is a simple example of material memory, in which microscopic structures retain information […]

Invisible Black Holes Could Be Triggering Supernovae

Primordial black holes may trigger some white dwarf explosions and leave measurable signatures in the Milky Way’s chemistry. Some Type Ia supernovae may begin with an invisible intruder passing through a white dwarf. An international research team has found that primordial black holes could trigger these stellar explosions and leave behind chemical patterns observed in […]

Scientists Test Natural Compounds Against Sarcoma: Which One Shows the Most Promise?

A laboratory study identified curcumin as the plant compound offering the best balance of anticancer activity and safety against fibrosarcoma cells. A plant compound can damage cancer cells in the laboratory yet still prove too toxic to become a useful treatment. That distinction emerged when researchers at Wroclaw Medical University and the University of Wroclaw […]
