Phys.org / A new species of tiny orange frog discovered in Brazil's cloud forests
Despite the vast numbers of animal species already identified, the natural world is still capable of springing a few surprises. Deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic ...
Phys.org / Ear piercings marked one of the earliest Maya rites of passage, research shows
In a recent study, Ph.D. candidate Yasmine Flynn-Arajdal studied iconographic representations of children in the Classic (ca. 250–950 AD) and Post-classic (ca. 950–1539 AD) imagery, as well as in ethnohistoric and ethnographic ...
Phys.org / Astronomers create first map of the sun's outer boundary
Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun's atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun's magnetic grasp. By combining the maps ...
Tech Xplore / Carbon capture made easier: Simple additive could slash costs for industrial plants
Capturing carbon dioxide from industrial plants is an important strategy in the efforts to reduce the impact of global climate change. It's used in many industries, including the production of petrochemicals, cement, and ...
Medical Xpress / From mind-controlling tech to clinical therapy: An optogenetics roadmap
Researchers at the University of Geneva, together with colleagues in Switzerland, France, the United States and Israel, describe how optogenetic control of brain cells and circuits is already steering both indirect neuromodulatory ...
Medical Xpress / Is narcissism a uniquely American trait? A new study suggests not
If you watch TV, read popular books or even study research articles, you may walk away believing narcissism is a uniquely United States-based characteristic, whether most common in American young adults, professionals in ...
Phys.org / Shape-shifting cell channel reveals new target for precision drugs
From small ions to large molecules, cellular gates control what can pass in and out of cells. But how one such gate, called pannexin-1 (PANX1), can handle vastly different cargo sizes has remained a long-standing mystery.
Phys.org / Hidden fuel for ocean microbes: Urea emerges as key energy source for marine ammonia oxidizers
Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen cycling. Yet, despite their ubiquity, scientists have long puzzled over how these microbes can flourish ...
Medical Xpress / Allergy risk varies by region: IgE profiles highlight environmental influence and hypoallergenic region
Allergic sensitization follows distinct regional patterns, and molecular IgE profiling can reveal these profiles in detail. An international research team has now demonstrated both phenomena in a population-based study of ...
Phys.org / Astronomers examine nuclear star cluster of nearby galaxy Messier 74
By analyzing the data from the PHANGS-MUSE survey, an international team of astronomers has inspected a nuclear star cluster of the nearby large spiral galaxy Messier 74. The new study presented Dec. 3 on the arXiv pre-print ...
Phys.org / Small galaxies may buck the black hole trend, Chandra finds
Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's Chandra X-ray Observatory. This contrasts with the common idea that nearly every galaxy has one of these ...
Medical Xpress / Clinicians now have powerful new tools to diagnose multiple sclerosis earlier
The faster patients can be diagnosed with multiple sclerosis, the sooner they can begin taking the powerful medications that can prevent further brain damage.
