Transforming Mars into a more Earth-like world could irreversibly destroy scientific evidence about the planet’s history and the possibility of extraterrestrial life. In an opinion article published in Eos, a team of Dutch, French and U.S. planetary scientists and ethicists warns that humanity risks destroying Mars’ scientific record before it has been fully explored.

The gas orbiting Sagittarius A (Sgr A*), the supermassive black hole at the center of the Milky Way galaxy, is rich in metals, researchers at McGill University’s Trottier Space Institute have found. The metal enrichment probably resulted from stars that exploded and released material into the black hole’s surroundings over time, they said.

Voltage fluctuations, light fluctuations, temperature fluctuations—any fluctuations are troublesome and thus undesirable. They don’t just cause discomfort; in engineering and medical applications, they affect the accuracy of measurements or introduce errors in controls. Even at the minute level of quantum phenomena, fluctuations are considered undesirable.

The Korea Research Institute of Standards and Science (KRISS) has remeasured a key transition frequency of the strontium (Sr) atom for the first time in 88 years, since 1938, using a photonic grating chip. It has established a new absolute frequency value with a measurement uncertainty reduced by more than 50 times. By providing an […]

Today’s computer technology, based on silicon chips, is slowly reaching its physical limits. Components cannot be miniaturized indefinitely, and clock speeds cannot be increased indefinitely. At the same time, huge AI data centers are being built in many places, and these consume an immense amount of electricity. This is why scientists around the world are […]
