Phys.org / Volcanic eruptions in Pacific Ring of Fire may have cooled Earth for centuries
For around 12,000 years, the Earth has been in the Holocene epoch, a warmer period following a glacial period. During this epoch, however, there have been around 22 abrupt cold phases, each lasting up to several centuries ...
Medical Xpress / Supercharged millet could help children's gut health without usual supplement side effects
Every day in the urban slums of Mumbai, hundreds of young children were fed toddler-appropriate porridge, soft curry or fresh-baked goods. For some, these were made of ordinary pearl millet, an ancient grain common in the ...
Phys.org / 2D quantum memory device reaches single-electron limit of information storage
Most electronic memory storage devices require the ability to trap large numbers of electrons for each bit of memory. In an ideal world, however, it would take only one electron. This would reduce space requirements and power ...
Phys.org / Fossil footprints reveal body size and group dynamics of 1.4-million-year-old human relative
Ancient footprints preserved along the shores of Kenya's Lake Turkana are reshaping scientists' understanding of one of humanity's extinct relatives. A paper published in Proceedings of the National Academy of Sciences describes ...
Phys.org / Before North and South America were connected, their mammals found a way to intermingle
Until the Panamanian isthmus formed about 2.8 million years ago, North and South America were isolated continents with unique groups of animals. A riot of marsupials—mammals with brood pouches—and sloths in the south contrasted ...
Phys.org / Learning may rely on stronger neural connections, not expanding networks
How does the brain learn? Does it acquire new knowledge by creating new neural pathways or by strengthening existing connections? A new study from Bar-Ilan University offers evidence in favor of the latter, suggesting that ...
Phys.org / Bacteria build a mineral shield that could help marine infrastructure resist rust
Researchers at Reichman University have developed a biological method for protecting marine infrastructure from corrosion caused by prolonged exposure to seawater. The study, published in Cell Reports Physical Science, presents ...
Phys.org / Natural emulsion manages to stop fungus that threatens up to 80% of cocoa production
An innovative formulation based on natural compounds could become a sustainable alternative for controlling moniliasis, one of the most devastating diseases affecting cocoa in Latin America. A new study shows that emulsions ...
Tech Xplore / Claude AI finds cryptography weaknesses human experts missed
AI company Anthropic has announced that its unreleased model, Claude Mythos Preview, has discovered previously unknown mathematical weaknesses in cryptographic algorithms that human researchers had missed for years.
Phys.org / Astronomers find strongest evidence yet that Betelgeuse has a companion
At long last, astronomers have firm evidence that Betelgeuse, one of the most famous stars in the night sky, is not alone. Using the European Southern Observatory's Very Large Telescope (ESO's VLT), a team led by French researcher ...
Phys.org / Electrically controlled magnetic switching shows promise for next-gen cryogenic devices
Researchers at the Indian Institute of Science (IISc) have demonstrated a new way of switching a material between two fundamentally different magnetic states using an electric current. The discovery could pave the way for ...
Phys.org / DNA studies uncover a forgotten population at the top of the world
Scientists have uncovered an ancient population previously unknown to science in Ladakh, a high-altitude region in northern India. Their studies revealed individuals with a nearly perfect 50–50 mix of South Asian-related ...
