Phys.org / Analyzing wildfire behavior can help detect risk zones earlier and support fire‑smart strategies
Fire-smart risk assessment is needed to tackle the scale of wildfire destruction, which is a growing reality across the globe. Hazardous fires are more intense and more frequent, fueled both by climate change and by the no ...
Phys.org / Primordial halo simulations reveal how cosmic storms shaped the universe's first stars
Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon or oxygen. Instead, vast clouds of ...
Medical Xpress / AI-based tissue anomaly detection may reduce duration of liver cancer surgery
A liver cancer diagnosis frequently leads to surgery, with the goal of completely removing all malignant tissue. To ensure that no tumor remains in the organ, the resected tissue is subjected to frozen-section analysis during ...
