Medical Xpress / How the heart's 'little brain' helps it function and protects it against stress
For years, scientists have known that the heart has its own network of nerves, the intrinsic cardiac nervous system (ICNS), sometimes called its "little brain." Exactly how it functions has remained something of a mystery, ...
Phys.org / Scientists pinpoint where cells first begin copying DNA
Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy of its genome. The findings, ...
Phys.org / Why evolution never produced mammal teeth that slice and crush equally well
Evolution is all about trade-offs. Traits that may be beneficial in one situation may backfire in another. Over millions of years, species can become specialized for one way of living rather than being equally good at everything. ...
Phys.org / International team evaluates anoxic marine basins as potential sites for carbon sequestration
Could taking plant biomass and burying it in the deep, anoxic parts of the ocean be a workable large-scale strategy for carbon sequestration? The concept has intrigued scientists for years, and now a recent international ...
Phys.org / Plumage reflectance framework offers new insight into how birds evolved heat-controlling feathers
Birds can inhabit various environments with different climates and temperatures, ranging from cold polar regions to scorching hot deserts. To survive and thrive in these very different environments, they need to effectively ...
Phys.org / How fishing may be changing one fish species at the molecular level
The pearly razorfish (Xyrichtys novacula) is a small marine animal that lives in sandy coastal waters and feeds on creatures like shrimp. Known locally in Spain's Balearic Islands as raors, it is a popular dish in many homes ...
Tech Xplore / AI gains a tool to identify Kinyarwanda propaganda, with promise for 600 Bantu languages
A new study led by Fabrice Niyigaba '27 reports the first digital tool for identifying online propaganda in Kinyarwanda, the national language of Rwanda's 15 million people—and possibly the first for any of the Bantu languages ...
Phys.org / Sustainability is not automatic: New model reveals local successes and regional barriers
Whether a region manages its land sustainably cannot be measured by land-use change alone. Sustainability is a delicate balance: it must be ecologically sound, legally secure and socially just. Yet capturing this interplay ...
Phys.org / Small tropical islands face dangerous humid heat by end of the century
Millions of people living on tropical islands could face a future of increasingly dangerous heat as climate change drives longer and more intense periods of humid conditions. While rising temperatures are often discussed ...
Phys.org / Mercury reveals short-lived radiation belts during its swing farther from the sun
Mercury was long considered the exception to the rule that magnetic planets have radiation belts similar to Earth's Van Allen belts, but a new study by University of Michigan Engineering and the University of California, ...
Phys.org / Long-term study finds widespread lithium in drinking water across communities in the western U.S.
Lithium in drinking water is a widespread and persistent source of human exposure across Tribal communities in the Western United States, according to a new study from Columbia University Mailman School of Public Health. ...
Medical Xpress / Weaker rest-activity rhythm, unfavorable sleep profile linked to overactive bladder
Weaker rest-activity rhythms (RARs) and unfavorable sleep profiles are associated with a higher prevalence of overactive bladder (OAB), according to a study published online July 17 in Neurourology and Urodynamics.
