Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers reporting in the journal Current Biology on May 6 have some of the first solid evidence that sharks also rely on magnetic fields...
Few sites in the world preserve a continuous archaeological record spanning millions of years. Wonderwerk Cave, located in South Africa's Kalahari Desert, is one of those rare sites. Meaning "miracle" in Afrikaans, Wonderwerk Cave has been identified as potentially the earliest cave occupation in the world and the site...
The latest assessment of Atlantic cod stocks, whose collapse crushed the economy of Newfoundland and Labrador, has scientists worried the species will never recover without drastic change within the federal Fisheries Department. The federal governmentreport shows the stock continues tocling for life in what officials classify as the critical zone,...
Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information...
Gray wolves are among the largest predators to have survived the extinction at the end of the last ice age around 11,700 years ago. Today, they can be found roaming Yukon’s boreal forest and tundra, with caribou and moose as their main sources of food. A new study led by...
The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA's Juno spacecraft has detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. SwRI scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions. "We think these newly discovered faint...
AT FIRST, the scene at DeGray Lake in Arkansas looked like a massacre. In 1994, 29 bald eagles were found dead nearby. It was the biggest undiagnosed die-off of bald eagles in history, and it was only getting started. By 1996, at least 70 eagles had died across several Arkansas...
A team of international scientists that includes a Canadian researcher said it has mapped, for the first time, the magnetic fields surrounding a black hole. The Event Horizon Telescope Collaboration team produced an image that shows electromagnetic fields that look like a "crisp swirl" of light around the black hole...
Understanding the evolution of the polar sea ice is not enough to study the effects of the climate change on marine ecosystems in Antarctic seafloors. It is also necessary to determine the intensity of phytoplankton local production during the Antarctic summer, as stated in a new study by a...
93-million-year-old shark would have resembled manta and devil rays. Researchers announced the discovery of a nearly complete fossil of the shark, called Aquilolamna milarcae, that lived during the Cretaceous Period at a time when dinosaurs ruled the land. Its unusual proportions – a fin span of about 6-1/4 feet (1.9 meters)...
