Trust in science ‘under pressure,’ global survey finds - CIDRAP

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.

The Futura Team represents the pulse of Futura’s editorial department, bringing together a collective expertise dedicated to the dissemination of scientific knowledge. Rather than the work of a single author, every article published under this signature is the result of a rigorous collaborative process involving journalists, editors, and fact-checkers. Specializing in news analysis via desk research and international wire services, the team focuses on transforming raw information into accessible, verified content. This curation and synthesis process ensures constant monitoring of technological innovations and major scientific breakthroughs. By cross-referencing sources and conducting multiple rounds of peer review, the Futura Team guarantees scientific accuracy and pedagogical clarity. This collective signature serves as a hallmark of trust, providing reactive, cross-disciplinary information at the forefront of current events Normally, when an asteroid swings by Earth, the burning question is simple: “Are we at risk?” Should we prepare for a massive space rock to pancake our planet? Not this time.

SpaceX's Dragon spacecraft docked with the International Space Station on October 15 and delivered more than 6,300 pounds of food, essential supplies and scientific equipment to the crew of Expedition 75. The cargo included equipment for manufacturing artificial retinas in microgravity, brain organoids, three-dimensional models of heart tissue and materials for studying a new type of glass. As ScienceDaily reports, Dragon docked with the space-facing port of the Harmony module at 10:27 a.m. Eastern Time. This is SpaceX's 35th commercial ISS resupply mission under a NASA contract. Research for medicineThe equipment for manufacturing artificial retinas is intended to help study the possibility of creating such structures in microgravity. Scientists hope these technologies may be useful for restoring vision on Earth in the future.3D models of heart tissue that reproduce important properties of the human heart were also sent to the station. They are planned to be used to improve methods for testing large numbers of potential medicines during future space missions. More current news is available on the UA.

Orcas are hunting great White Sharks around the world, scientists confirmThe killing of great whites by orcas has been reported in the waters of South Africa, California, and Australia, and the implications that the hunting behaviour would have on the marine ecosystem have been considered. In fact, it all started back on May 3, 2017, when the body of a female great white, weighing 1,100 kilograms, washed ashore in Gansbaai, close to Cape Town, with a deep gash through which its 90-kilogram liver had been extracted. Five more corpses of great whites appeared with similar wounds in the coming months, as claimed by shark biologist Alison Towner of Rhodes University. Two adult males, called Port and Starboard, who are supposed to be brothers judging by their dorsal fins that fold differently, were identified as the most probable perpetrators. The connection was officially established in 2022 based on video footage of a drone that caught three orcas chasing and biting a 3-meter great white off Mossel Bay. The sharks quickly disappeared from Dyer Island, one of the best places in the world to witness a great white.
