Phys.org / Global study finds smaller fish and shifting food webs despite stable species numbers
Species numbers alone do not fully capture how ecosystems are changing. In a global study, scientists analyzed long-term data from nearly 15,000 marine and freshwater fish communities. They found that fish food webs have ...
Phys.org / Novel bacteria discovered in Florida's stranded pygmy sperm whales
Pygmy sperm whales (Kogia breviceps) are among the ocean's most enigmatic inhabitants—rarely seen and largely unstudied. They live far offshore in small groups, diving in search of squid and fish. Their quiet behavior and ...
Phys.org / Flickering glacial climate may have shaped early human evolution
Researchers have identified a "tipping point" about 2.7 million years ago when global climate conditions switched from being relatively warm and stable to cold and chaotic, as continental ice sheets expanded in the Northern ...
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 / Earliest evidence of indigo-dyed textiles and single-needle knitting discovered in Bronze Age Anatolia
A research team led by Assoc. Prof. Dr. Çiğdem Maner from Koç University's Department of Archaeology and History of Art has uncovered remarkable textile fragments at Beycesultan Höyük that rewrite our understanding of ...
Medical Xpress / The postpartum experience: Recognizing complications
Postpartum experiences are as unique as the pregnancies that come before them. Because of this, it can be difficult to recognize what's normal and what could be a complication—even if you've given birth before.
Phys.org / Prehistoric fossil poses puzzles in shark research
A newly examined prehistoric shark from the age of dinosaurs provides surprising insights into the early evolution of modern sharks. It cannot be confidently assigned to any shark order that exists today and thus calls into ...
Tech Xplore / Exposing biases, moods, personalities and abstract concepts hidden in large language models
By now, ChatGPT, Claude, and other large language models have accumulated so much human knowledge that they're far from simple answer-generators; they can also express abstract concepts, such as certain tones, personalities, ...
Medical Xpress / AI reads clinical notes to forecast colitis-linked colorectal cancer
People with ulcerative colitis (UC), a chronic inflammatory bowel disease, are up to four times more likely to develop colorectal cancer than the general population. Low-grade dysplasia (LGD)—abnormal or precancerous lesions—can ...
Phys.org / Eclipse research finds turbulent times in the sun's corona
Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses. Drawing on more than ...
Phys.org / Antarctic warming is altering atmospheric stability: New evidence from the 1950s to the present
A new study published in the Journal of Climate reveals how surface warming in Antarctica, particularly over the Antarctic Peninsula, is significantly altering the stability of the lowest layers of the atmosphere.
Phys.org / New species of ancient crocodile named in honor of Welsh school teacher
A new species of crocodylomorph dating to about 215 million years ago has been described from the U.K. It has been called Galahadosuchus jonesi in recognition of David Rhys Jones, a secondary school physics teacher from Ysgol ...
