FAYETTEVILLE, GA, UNITED STATES, July 3, 2026 / / — Researchers have engineered a multifunctional gallium-doped bioactive glass that selectively kills osteosarcoma cells and prevents bacterial infections while promoting bone regeneration. By localized delivery of gallium ions, this innovative biomaterial disrupts iron metabolism in cancer cells, triggering programmed cell death without harming healthy bone tissue. It simultaneously provides a robust defense against hospital-acquired [...]

Tropical forests are one of the planet's most important carbon sinks – often also called "the lungs of our Earth". But their future in a high-CO₂ world remains uncertain. New research from the Central Amazon with researchers from the University of Vienna, the Technical University of Munich, and the National Institute for Amazon Research, Manaus, suggests even small understory trees may initially buffer climate change more strongly. But their long-term capacity to store carbon could be [...]

New method can significantly reduce energy required for manufacturing operations

Newswise — To find new ways to shield hair from heat, sunlight and air pollution, researchers in Brazil are turning to vegan-friendly ingredients for shampoos and conditioners. Published in ACS Omega, early tests show that a fruit-algae combination added to haircare products coats strands with a protective film. Although the botanical film makes hair slightly less elastic, it improves shine and makes locks easier to comb compared to hair washed and conditioned with products not containing the [...]

Titan, Saturn's largest natural satellite, captivates scientists with its Earth-like processes, dense nitrogen atmosphere, and surface lakes of liquid hydrocarbons. However, its nonuniform gravity field, thick haze, and low solar energy pose major obstacles for orbital missions. Traditional single-satellite systems struggle to balance coverage, stability, and data transmission under such conditions. Moreover, the gravitational pull from Saturn and nearby moons further complicates orbital [...]

Leading science institutions and partners highlight ocean–forest interconnection and the ocean’s role in global climate solutions at COP30 Author More than a dozen of the world’s leading ocean science, philanthropic, and stakeholder organizations—led by the Woods Hole Oceanographic Institution (WHOI) and Scripps Institution of Oceanography at the University of California San Diego—to champion the ocean’s role in climate action at the 30th United Nations [...]

The first global comprehensive review identifies three fundamental mechanisms of psychological distress associated with firearm use and accessibility

Researchers from the University of São Paulo and Goiás State University have developed a pioneering screening approach to evaluate advanced oxidative processes (AOPs) for degrading emerging contaminants, as reported in a recent study published in Frontiers of Chemical Science and Engineering. Advanced oxidation processes are crucial for addressing the challenge of removing emerging contaminants, such as pharmaceuticals, from water systems. However, there is a need for efficient [...]

Newswise — SAN FRANCISCO— The age at which a woman has her first period can offer valuable clues about her long-term risk for conditions like obesity, diabetes, heart disease and reproductive health issues, according to a study being presented Sunday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif. The Brazilian study found that both early and late menarche—the age when women first get their period—are linked to different health [...]
