The story of Earth’s first animals may need rewriting after ancient fossils revealed an earlier start to complex life. From butterflies to blue whales, corals, and worms, Earth is home to an incredible diversity of animals. How all of these animals evolved from earlier, simpler ancestors is one of the most exciting stories in the […]
567-Million-Year-Old Fossils Suggest Animals Evolved Earlier Than We Thought
The story of Earth’s first animals may need rewriting after ancient fossils revealed an earlier start to complex life. From butterflies to blue whales, corals, and worms, Earth is home to an incredible diversity of animals. How all of these animals evolved from earlier, simpler ancestors is one of the most exciting stories in the […]
Ancient DNA Reveals the Hidden Origins of China’s Mysterious Shimao Civilization
Ancient DNA from Shimao reveals local origins, broad prehistoric connections, a patrilineal social structure, and gender-specific patterns of human sacrifice. At Shimao, a vast stone-walled settlement in northern China, ancient DNA is filling in details that archaeology alone could not fully resolve. The genetic evidence is helping trace where the people of this late Neolithic […]
Scientists Finally Solve a 50-Year Mystery Hidden in Solid Nitrogen
Researchers have uncovered compelling evidence about the elusive structure of a high-pressure phase of solid nitrogen. Nitrogen makes up most of Earth’s atmosphere, but under intense pressure and low temperatures, it can form solid phases with unexpectedly complex structures. One of these phases, γ-N2, remained poorly understood for more than 50 years despite repeated experimental […]

Saturn’s Largest Moon May Hold the Resources for a Space Colony
Titan’s resources could one day make Saturn’s largest moon a major outpost for deep space exploration. Titan is one of the few places in the Solar System where the landscape can feel strangely familiar and completely alien at the same time. Saturn’s largest moon has weather, clouds, rain, lakes, and seas, but its cycle is […]
New Strategy Could Break Pancreatic Cancer’s Protective Shield
A newly identified inflammatory signaling target may help weaken the protective environment surrounding pancreatic tumors and make existing treatments more effective. Pancreatic tumors are not made up of cancer cells alone. They are surrounded by scar-like tissue, immune cells, and support cells that can shield the disease from treatment. A new study suggests that disrupting […]
