Phys.org / From cells to companies: Study shows how diversity scales within complex systems
A mystery novel, a history book, and a fantasy epic may have little in common in plot or style. But count the words inside them and a strange regularity appears: many new words show up early, then fewer and fewer as the author ...
Phys.org / A yeast enzyme helps human cells overcome mitochondrial defects
Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most animal cells, this process depends closely on properly functioning mitochondria, the organelles ...
Phys.org / Tuned nanocrystals speed light-driven reactions by matching molecular vibrations
Adjusting the size and chemistry of nanocrystals within an ultrathin surface can speed up light-driven chemical reactions, according to a University of Michigan Engineering study published in the Journal of the American Chemical ...
Phys.org / Long-term radio observations probe a relativistic binary pulsar system
Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver important information ...
Phys.org / Intensive grazing and soil fertility favor the growth of non-native plants, drylands study finds
A global study has revealed the conditions under which non-native plants thrive in the world's many dryland regions and the factors that limit their spread. Using data from 98 study sites across 25 countries on six continents, ...
Phys.org / Climbing behaviors of tree-dwelling mammals unlock insights on early primate evolution
Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their environments, providing insights into the evolution of the distinct upright postures seen in primates. The ...
Phys.org / Longer roots for drought? How an edited protein could reshape crop resilience
What's the key to growing resilient crops that can survive tough conditions? Researchers at the University of Missouri are getting to the root of it—literally. Researchers in the Walter Gassmann lab at Mizzou's Bond Life ...
Phys.org / Tropical forests generate rainfall worth billions, study finds
Tropical forests help to generate vast amounts of rainfall each year, adding weight to arguments for protecting them as water and climate pressures increase, say researchers. A new study led by the University of Leeds has ...
Medical Xpress / Single dose of a psychedelic drug can rapidly reduce depressive symptoms, clinical trial suggests
A single dose of the psychedelic drug dimethyltryptamine (DMT), given with psychological support, rapidly reduced depressive symptoms in 34 adults with major depressive disorder, according to a clinical trial published in ...
Phys.org / To aficionados, fungi are freaky, mystical and overlooked. They're helping scientists learn more
Jessica Allen crunched through fallen leaves among Manzanita trees hunting for something few have spotted before: the Manzanita butter clump—a rare and little-known yellow mushroom found, so far, only along North America's ...
Phys.org / Can seagrass survive extreme heat? Exploring how different species withstand elevated water temperatures
Extreme heat can have a devastating effect on seagrass, but new research from Edith Cowan University (ECU) could shape how these vitally important marine ecosystems are managed and restored. In separate studies carried out ...
Medical Xpress / AI-powered liquid biopsy can classify pediatric brain tumors with 92% accuracy
Liquid biopsies, which test body fluids that contain cancerous material, including circulating tumor DNA (ctDNA), are a noninvasive way to learn about a cancer's biology. However, technological limitations with the small ...
