In a new Nature Physics study, researchers found that fin regrowth in zebrafish is driven by a brief burst of growth signal at the fin tip, sized to the amount lost, which sets up gradients of Erk activity that guide the ...
The Cambrian explosion was a major diversification of animal life that unfolded early in the Cambrian period, which began around 538.8 million years ago. During this interval, marine animals became much more varied, building ...
The Terracotta Army near Xi'an, China, is a breathtaking sight: thousands of life-size terracotta figures created in the third century B.C. to guard the tomb of Emperor Qin Shihuang. They were discovered in 1974, and people ...
When Earth formed billions of years ago, its metallic core was wrapped in a global ocean of molten rock, which eventually cooled and crystallized to form the mantle. Today, when deep-rooted mantle plumes rise toward the surface ...
Whether we are waiting for a car windshield to defrost in winter or a warm drink to cool down, how long it takes for an object to settle into a stable, even temperature within its environment (thermal equilibrium) depends ...
The world's oceans help slow climate change by absorbing carbon dioxide (CO₂) from the atmosphere, but how much they take up can vary throughout the year. New research, published in Geophysical Research Letters, suggests ...
Close social relationships are known to contribute to the survival of many animals, including humans. Maintaining social bonds over time, however, can also require effort and sacrifices.
Astronomers using China's FAST radio telescope have discovered a compact cloud of hydrogen with no visible stars or galaxy around it. This could be one of the strongest candidates yet for an isolated "dark galaxy," containing ...
Qubits, the quantum equivalent of digital bits, are fragile and prone to errors. That makes building reliable quantum computers extremely difficult. One fix has been to use traditional magic state distillation, which filters ...
The ocean beneath Saturn's moon Enceladus lies under kilometers of ice, but some of its contents do reach the surface. Jets near the south pole spray out water vapor and icy particles, offering a way to investigate the hidden ...
