The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
Swidden agriculture—often called "slash-and-burn"—has been practiced on every inhabited continent throughout human history, and for decades it has been blamed for the destruction of the world's rainforests. However, a new ...
As the construction of a hydroelectric dam loomed, archaeologists raced to uncover Angola's earliest dated burials and its only known cremation at a 15th-century settlement before it vanished beneath the water.
Logically, you would think a sleek surface has optimal aerodynamics—but recent research at Tohoku University turns this fundamental principle on its head. Applying an irregular microscale surface texture reduced the aerodynamic ...
Stars and galaxies make up much of the universe's ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more.
While humans are inherently social beings, psychology studies suggest that their social skills are gradually fine-tuned over time and with experience. Understanding when different social skills emerge and how they typically ...
If you look up invasive species in a textbook, there's a good chance you'll find a picture of a brown tree snake. Native to Australia and the South Pacific, the brown tree snake arrived on Guam sometime after World War II, ...
Venus is an inhospitable place, with temperatures soaring to several hundred degrees Celsius (hundreds of degrees Fahrenheit) and no oceans like those on Earth. Planetary scientists long believed Venus was geologically dormant. ...
A careful statistical comparison of observations recorded by NASA's Juno mission and the Planetary Science Institute's Io Input Output observatory (IoIO) shows that IoIO observations reliably predict the density of Jupiter's ...
NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth–based auroras.
