Software trained to identify fences from aerial images could help wildlife managers prevent pronghorn from getting stuck and starving As many as 1 million kilometers of fence may crisscross the western United States, enough to stretch to the Moon and back. Erected over the past century, largely to contain livestock, the barbed and woven wire fences also…
For most animals, aging is a one-way street. But not in the sea walnut, a type of comb jelly about the size of a mango that’s native to the eastern Atlantic Ocean. When the going gets tough, the transparent invertebrate ages in reverse, regressing to a tentacled larval form. Then, when conditions improve, it matures…
Neutrinos are fundamental particles that are notoriously difficult to detect due to their weak interactions with matter. For decades, scientists faced a puzzle known as the “missing neutrinos” problem. Observations of solar neutrinos—produced in the sun’s core—revealed fewer particles than expected based on theoretical models of nuclear fusion. This discrepancy suggested that something fundamental was…
Quantum entanglement is a phenomenon that defies classical intuitions about the separability and independence of distant objects. According to quantum mechanics, when particles become entangled, their quantum states are interdependent no matter the distance separating them. This means that measuring the state of one entangled particle instantly determines the state of the other, regardless of…
Dark matter is one of the most intriguing and elusive components of the cosmos. Although it does not interact with electromagnetic forces, meaning it neither emits nor absorbs light, its presence is inferred through its gravitational effects on visible matter. Scientists estimate that dark matter constitutes approximately 27% of the universe’s total mass and energy….
