Sep. 13, 2023 — A pioneering study has shed new light on North African humid periods that have occurred over the past 800,000 years and explains why the Sahara Desert was periodically ...
Aug. 6, 2024 — Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts ...
Oct. 3, 2022 — Scientists have made a key breakthrough in the quest to accurately predict fluctuations in the rotation of the Earth and so the length of the day -- potentially opening up new predictions for the ...
Dec. 13, 2022 — Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago. Researchers found the shape of Earth's orbit, or ...
May 21, 2024 — Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, ...
Apr. 3, 2024 — Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been ...
Sep. 15, 2022 — To improve understanding of variation of Earth's rotation in the 4th--7th centuries CE, a research team analyzed Byzantine records from this period to identify total solar eclipses around the ...
May 15, 2023 — A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show ...
May 16, 2023 — A team of physicists has discovered a new role for a specific type of turbulence -- a finding that sheds light on fluid flows ranging from the Earth's liquid core to boiling ...
Nov. 9, 2022 — Earth is closer to the sun at some times of year than at others, with the time of closest approach shifting over a period of 22,000 years. This affects Earth's climate, including ice ages, but a ...
