Phys.org / Hawaiian blueberries traced back to Northeast Asia in surprising discovery
Scientists at the Botanical Research Institute of Texas (BRIT) and University of Florida have solved a botanical mystery: Hawaii's wild blueberries originally came from temperate East Asia, not North America as expected.
Phys.org / Specialized potteries reveal complex organization of El Argar society 4,000 years ago
Most of the pottery recovered from political and administrative centers in El Argar (2200-1550 BCE), such as Tira del Lienzo and Ifre, located in the province of Murcia, was not produced locally, but rather at sites located ...
Phys.org / How cells orchestrate protein production through ER-lysosome interactions
Janelia researchers have uncovered a novel way that two of the structures inside cells—the endoplasmic reticulum (ER) and lysosomes—coordinate the production of proteins, highlighting how interactions between organelles ...
Phys.org / How plastics grip metals at the atomic scale: Molecular insights pave way for better transportation materials
What makes some plastics stick to metal without any glue? Osaka Metropolitan University scientists have peered into the invisible adhesive zone that forms between certain plastics and metals—one atom at a time—to uncover ...
Phys.org / Climate conference's webpages emit 10 times more carbon than average sites, study says
Websites produced for COP conferences emit up to 10 times more carbon than average internet pages, new research published in the journal PLOS Climate suggests.
Phys.org / AI bias in hiring decisions is often copied by human reviewers, study reveals
An organization drafts a job listing with artificial intelligence. Droves of applicants conjure résumés and cover letters with chatbots. Another AI system sifts through those applications, passing recommendations to hiring ...
Phys.org / Edible oat protein nanofibrils can combat iron deficiency more effectively
Iron deficiency is widespread globally. Women are particularly affected, with one in five in Europe suffering from iron deficiency. The consequences are anemia, constant fatigue, chronic headaches and a weakened immune system.
Phys.org / Sex-determination gene in bees and ants identified
Most species on Earth exist as two biological sexes, and the exchange of genes between males and females is vital for their survival. Yet, what actually determines whether an individual develops into a male or female varies ...
Phys.org / Urban greenness for mental health benefits: Researchers uncover optimal 'dose'
As cities around the world grapple with escalating mental health challenges, researchers from The University of Hong Kong (HKU) have pinpointed the ideal levels of urban greenness that maximize psychological well-being. Published ...
Phys.org / How a major Bay Area earthquake could endanger health care access
No one knows when the next major earthquake will strike. In the meantime, researchers are working to understand how these events could disrupt access to health care in densely populated regions—and how best to prepare for ...
Phys.org / Machine learning automates material analysis and design using X-ray spectroscopy data
Understanding the properties of different materials is an important step in material design. X-ray absorption spectroscopy (XAS) is an important technique for this, as it reveals detailed insights about a material's composition, ...
Phys.org / Explainable AI reveals how chemical sensors detect odors
NIMS has been developing chemical sensors as a key component of artificial olfaction technology (olfactory sensors), with the aim of putting this technology into practical use. In a new study, explainable AI (XAI) was used ...
