Phys.org / Orca tail dolphins to hunt salmon—and may share the catch
Killer whales or orca (Orcinus orca) have been observed hunting with Pacific white-sided dolphins (Lagenorhynchus obliquidens) in the waters off British Columbia, Canada, and sharing fish scraps with them after making a kill, ...
Phys.org / Twisting spins: Researchers explore chemical boundaries to create new magnetic material
Florida State University researchers have created a new crystalline material with unusual magnetic patterns that could be used for breakthroughs in data storage and quantum technologies.
Phys.org / Unlocking the sun's magnetic secrets: AI-powered mapping reveals intricate 3D details
Researchers at the University of Hawaiʻi Institute for Astronomy (IfA) are helping reshape how scientists study the sun. The UH-led team has developed a new artificial intelligence (AI) tool that can map the sun's magnetic ...
Phys.org / Canary Islands may be 'missing link' in global sea urchin killer pandemic
Sea urchins are ecosystem engineers, the marine equivalent of mega-herbivores on land. By grazing and shredding seaweed and seagrass, they control algal growth and promote the survival of slow-growing organisms like corals ...
Phys.org / Infrared radiation may be one of the most ancient plant signals to pollinating insects
Harvard researchers have discovered that cycads—one of the oldest living lineages of seed plants—heat up their reproductive organs to attract beetle pollinators and the insects possess infrared sensors to detect these ...
Phys.org / Tracing a path through photosynthesis to food security
The energy that plants capture from sunlight through photosynthesis provides the source of nearly all of humanity's food. Yet the process of photosynthesis has inefficiencies that limit crop productivity, especially in a ...
Phys.org / Dual substitution induces room-temperature ferromagnetism and negative thermal expansion in BiFeO₃
Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ...
Phys.org / Break the mold: Who defines the 'real' chemist?
The perception of a chemist varies. Some might imagine the "mad scientist" from old cartoons—a white-haired older man working with beakers in his lab—but as that cliche fades, the reality of what constitutes a chemist's ...
Phys.org / Scientists teach helices to switch shapes
Researchers at the University of Jyväskylä have discovered a simple way to program synthetic molecules so they can form specific spiral-like structures by embedding instructions directly into their sequence. This breakthrough ...
Phys.org / Lab-developed mosquitoes prevent malaria parasite development, paving way for future field trials
In a new study published in Nature, scientists have successfully developed genetically modified mosquitoes in Tanzania that block the transmission of malaria. The team includes researchers from the Ifakara Health Institute ...
Phys.org / How extreme weather events affect agricultural trade between US states
The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting ...
Phys.org / A biochip built for the next pandemic can test dozens of viral antigens at once
In 2020, as scientists around the world were racing to understand COVID-19, Prof. Roy Bar-Ziv and his team at the Weizmann Institute of Science started developing a DNA chip that could not only quickly show how our immune ...
