Apr 4th, 2026 - Viking announced its two newest ships for the Nile River—the Viking Ptah and the Viking Sekhmet—have been "floated out," marking a major construction milestone and the first time the ships have touched water. Set to debut in September and November 2026, respectively, the Viking Ptah and the Viking Sekhmet will join the company's growing fleet of state-of-the-art ships in Egypt and will sail Viking's popular 12-day Pharaohs & Pyramids itinerary. "Egypt is truly a phenomenal destination, distinguished by its remarkable history, enduring culture and the singular power of the Nile," ... [Read More]

Apr 3rd, 2026 - An ocean conservation ship operated by anti-whaling campaigner Paul Watson collided Tuesday with a commercial krill trawler off Antarctica in what the fishing vessel's owner described as a "deliberate attack," but activists called "a David-and-Goliath battle against an industrial giant." The Captain Paul Watson Foundation (CPWF) said on Facebook that, as part of its Operation Krill Wars campaign, the Bandero is currently targeting "two of the largest Norwegian trawlers operating in Antarctic waters, the Antarctic Endurance and the Antarctic Sea ,"—both of which are owned by Aker QRILL ...

Apr 2nd, 2026 - Anchor a sustainable design with resilient trees and shrubs that laugh in the face of drought Water-wise woodies: Try these 10 drought-tolerant trees and shrubs Change is the nature of nature, but knowing that doesn't make accepting those changes any easier. Droughts are becoming more frequent and more intense across North America, even in areas where they were not previously a concern. Gardeners in regions that don't experience long periods of drought may still be faced with increased periods of extreme heat or cold, which can put plants under water stress. One way to smooth the bumpy ride ... [Read More]

Apr 2nd, 2026 - HONG KONG — More than half a century after the United States put humans on the moon, it is once again locked in a space race. This one is with China. NASA sent astronauts on a lunar flyby on Wednesday, a milestone toward grander ambitions. Both the United States and China want to build outposts around the moon's south pole and hope to tap frozen water, hydrogen, and helium there. Both countries plan to build nuclear reactors to power lunar bases from which they can launch missions into deep space. It is a new frontier, and whoever gets there first will have a big say in setting the ... [Read More]

Apr 2nd, 2026 - Reading time 3 minutes Octopuses are some of the most mysterious animals living in the sea. In research out today, however, scientists have pulled back the curtain on the male octopus' penis-like arm, formally known as the hectocotylus. Researchers at Harvard University and elsewhere studied octopus mating across a series of experiments. To their surprise, they discovered the hectocotylus isn't just used to deliver sperm—it's also a sensory organ, one that can chemically detect exactly where in the female's body that sperm has to go. The findings not only illuminate more about these ... [Read More]

Apr 2nd, 2026 - A new quantum algorithm ran a 15-step nonlinear fluid simulation around a solid obstacle on real quantum hardware, the most physically complex publicly documented demonstration of its kind. The technique reduces qubit requirements and circuit depth, bringing industrial CFD applications closer to feasibility. Finnish simulation company Quanscient and quantum middleware developer Haiqu have demonstrated what they describe as the most physically complex quantum computational fluid dynamics simulation run to date on real hardware. The two companies ran a 15-step nonlinear fluid simulation around ... [Read More]

Apr 2nd, 2026 - The world cheered when Alex Honnold free-climbed a 101-story skyscraper in Taipei. Gather now, fickle public, to applaud the new free-climbing champion: the shellear, a fish that is about the size of a ziti noodle—and that can scale a 50-foot waterfall. During major floods, thousands of tiny fish convene at Luvilombo Falls in the upper Congo River Basin to undertake a peculiar vertical migration , described for the first time today in Scientific Reports . At sunset they sidle up to the splash zone—the damp areas on either side of the waterfall's main flow—and press their ... [Read More]

Apr 2nd, 2026 - Where digital holographic microscopy complements fluorescence microscopy   Understanding how living cells grow, respond to stimuli, and change over time is central to modern cell biology and drug discovery. Many traditional imaging approaches rely on fluorescent labels, which can introduce phototoxicity, bleaching, or unintended effects on cellular behavior. Digital Holographic Microscopy (DHM), a form of quantitative phase imaging, offers a powerful, label-free alternative that enables real-time monitoring of cellular morphology and intracellular dynamics over long time scales without ...
