Phys.org / Unraveling a long-standing solar mystery: The extreme thinness of the sun's tachocline layer
Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun's tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions ...
Phys.org / Maize-fed animals may have helped Maya farmers solve corn's protein deficiency
Maize (corn) is a major dietary staple in Maya communities past and present because of its reliability, potential for surplus, and suitability as both food and fodder. It became so important to ancient Mesoamerican communities ...
Medical Xpress / Not all birth controls are equal, some are linked to higher risk of brain tumors, study finds
Meningiomas are the most common brain tumors in adults, accounting for 38% to 42% of all primary central nervous system tumors. According to 2021 WHO data, 874 million of the world's 1.9 billion women of reproductive age ...
Phys.org / Space sensor could spot hidden nuclear weapons in orbit with 99% accuracy
In 2024, a U.S. government official warned that Russia could be developing a new satellite designed to carry nuclear weapons into space. The statement followed the launch of a suspicious Russian satellite into low-Earth orbit ...
Phys.org / Tiny 60,000-neuron ant brains reveal how parental care evolved from feeding circuits
Long before the dawn of modern parenting, animals laid eggs and moved on, leaving their progeny to fend for themselves. Now, a study published in Nature uncovers one of the elegant ways evolution transformed neglect into ...
Phys.org / Metallic rutile oxides break the rules of cooling
Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, ...
Medical Xpress / Decline in work productivity found 15 years before early-onset dementia diagnosis
People diagnosed with early-onset dementia had reduced work productivity up to 15 years before diagnosis, according to a study published in Neurology. Researchers also found the number of years of lower productivity varied ...
Phys.org / California wolves feed heavily on cattle and their presence causes significant stress among livestock
Two new studies examining gray wolves in California paint a complex picture of life on the state's ranching landscapes: Wolves eat cattle more than anything else, and the presence of the predators causes significant stress ...
Tech Xplore / Rust-to-iron cycle may unlock long-term storage for renewable energy
In the future, iron might be used as a chemical energy storage material, making large quantities of renewable energy available in the long term. Iron powder is combusted in a cyclic process that is carbon neutral and then ...
Phys.org / Optimizing RNA design with AI and an Ising machine: Encoding matters
RNA has emerged as one of the most promising molecules in modern medicine, enabling advances from mRNA vaccines and gene therapies to genome editing and synthetic biology. However, designing RNA molecules that reliably fold ...
Phys.org / Nature's puncture tools reveal shape trade-offs between piercing power and strength
Nature has invented countless types of pointy appendages, and scientists have long sought to explain what makes these structures so effective at puncturing other things. A new study models the key physical characteristics ...
Medical Xpress / New, improved method to find and isolate the strongest cancer-fighting immune cells
A new platform developed by researchers at the University of Texas MD Anderson Cancer Center quickly finds and isolates rare, tumor-reactive immune cells that are especially good at recognizing and attacking cancer cells, ...
