Phys.org / Why gradual environmental change can trigger sudden species collapse and fragmented populations

When species are subjected to changing environments, they can survive in their current location through genetic adaptation. However, this ability is not unlimited. In a study published in PNAS, biomathematician Jitka Polechová ...

Medical Xpress / Testosterone treatment found to improve sexual and physical function for men after prostate cancer surgery

Most men with low-grade prostate cancer have an excellent prognosis, with a five-year survival rate of more than 99%. But radical prostatectomy—surgery to remove the prostate—can lead to sexual and physical dysfunction, fatigue, ...

Phys.org / Climate patterns may shape where violent conflict risks are amplified

A new Rice University study is shedding light on a long-debated question: Can climate variability influence the risk of armed conflict? The answer, researchers say, is yes—but in more nuanced and region-specific ways than ...

Phys.org / How carbon dioxide cools the upper atmosphere—and warms Earth below

Even as temperatures rise on Earth's surface and in the lower atmosphere, the planet's upper atmosphere has cooled dramatically. This paradoxical pattern is a well-known sign of humanity's climate impacts—but until now, the ...
