The researchers intend to further investigate its natural processes.Research conducted by scientists from the…

Mars’s influence on Earth may be greater than we thought. In fact, the Red Planet, located over 140 million miles away from Earth, could actually be driving giant whirlpools in the deepest parts of our oceans. New research has revealed that changes in the deep-sea currents found on Earth appear to coincide with times when Mars and Earth interacted while orbiting the Sun.The culprit of this influence is something we call resonance. Astronomers describe resonance as a phenomenon where two orbiting bodies – in this…

In the autumn of 2010, a La Niña event is formed in the tropical Pacific, characterized by a high Chl concentration. At the same time, tropical instability waves (TIWs) are active, which gives rise to large CHL perturbations as clearly observed in the eastern-central equatorial Pacific. These multiscale CHL perturbations exert effects on penetrative solar radiation in the upper ocean. Credit: Science China Press In as study…

The New Jersey band have prepped a hard rock cover of the track for their upcoming EP, History Books — Short Stories The Gaslight Anthem will cover a Billie Eilish smash and give one of their own deep cut classics a new spin on the upcoming EP, History Books — Short Stories, out this Friday, March 22.  The four-track project will be anchored by a rendition of Eilish’s breakthrough hit, “Ocean Eyes,” which frontman Brian Fallon learned about from his daughter. “I was driving my daughter to school…

Our world may seem fragile, but Earth has been around for a very long time. If we ventured far back into the past, would we reach a time when it looked fundamentally different? The answer lies in some of the earliest extensive relics of Earth's surface, found in a remote corner of southern Africa's highveld—a region known to geologists as the Barberton Greenstone Belt. The geological formations in this region have proved difficult…

For the ninth straight month, Earth has obliterated global heat records — with February, the winter as a whole and the world's oceans setting new high-temperature marks, according to the European Union climate agency Copernicus.The latest record-breaking in this climate change-fuelled global hot streak includes sea surface temperatures that weren't just the hottest for February, but eclipsed any month on record, soaring past August 2023's mark and still rising at the end of the month.And February, as well the previous two…

Federal authorities have closed Canada's only known live coral reef in the Pacific Ocean to all commercial and recreational bottom-contact fishing.Fisheries and Oceans Canada says the indefinite closure came into effect on Feb. 14 for the Lophelia Reef, located in the Finlayson Channel of British Columbia's Central Coast, about 500 kilometres northwest of Vancouver and 200 kilometres directly east of Haida Gwaii.The department says the reef was first discovered in 2021 and is the "first and only" known live coral reef in…

Quirks and Quarks17:24How documenting the disappearance of the great auk led to the discovery of extinctionWhen species cease to exist, we often say they went "the way of the dodo." But it might be more fitting to say they went "the way of the great auk" because it was the Icelandic bird's disappearance that led to the discovery that humans activities could make a species go extinct.In his book The Last of Its Kind: The Search for the Great Auk and the Discovery of Extinction, Gísli Pálsson retraces a 1858 trip two…

Artist’s depiction of OSAM-1 docking with a satellite.Image: NASAAn ambitious NASA project designed to test satellite refueling in space, known as OSAM-1, has been discontinued after significant technical, cost, and scheduling difficulties. The cancellation comes in the wake of an October 2023 report from NASA’s Office of Inspector General that cited “poor performance” by Maxar, the primary contractor for the project. - George Dvorsky Read More Artist’s depiction of OSAM-1 docking with a satellite.Image: NASAAn…
