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 previously understood.
Researchers have cautioned that well-intended suggested changes to carbon markets risk worsening climate impacts if core safeguards are weakened. Climate change, biodiversity loss and human rights are deeply interconnected challenges, often sharing solutions that can deliver
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 underlying physics has remained a mystery.
Under the lead of the Leibniz Institute for Baltic Sea Research Warnemünde (IOW), climate simulations were used to investigate how 19 inland seas, including the Baltic Sea, are responding to climate change. The researchers found that they have been warming faster than the
Researchers at MIT have suggested that rice seeds can hear the sound of rain, according to a new study. MIT calls it "the first direct evidence that plant seeds and seedlings can sense sounds in nature." Perhaps surprisingly, the effects reported in this new study are not as
Most of what scientists know about face development comes from studies in bony vertebrates such as mice, chickens, and zebrafish. However, their evolutionary counterparts, cartilaginous fishes, have remained largely unexplored. This gap has limited our understanding of how
Entropy gets a bad rap. Typically associated with randomness and chaos, it can also correlate with freedom and diversity. Cornell researchers have found that, thanks to the latter qualities, entropy can help bind certain pairs of molecules faster and more robustly—an approach
In Baltimore on Oct. 20, 2025, a 17-year-old student named Taki Allen was sitting outside his high school after football practice when an artificial intelligence-enhanced surveillance camera falsely identified the Doritos bag in his pocket as a gun. Within moments, police cars
