In patients of reproductive age who have cancer, fertility preservation for potential children in the future should be a high priority. A practice article published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.250519 describes the successful preservation of ovarian tissue in a young woman undergoing urgent chemotherapy and demonstrates a novel model of care for Canada. “This case illustrates the complex challenges faced by young patients with cancer who desire biological children but require urgent treatment that threatens their reproductive potential,” ...

Generative Artificial Intelligence could result in a renewed emphasis on conversational approaches to teaching, researchers say, as chatbots make it easier to bypass recall-based learning and test the limits of traditional exams. In a new conceptual paper, researchers at the University of Cambridge argue that AI raises questions for aspects of traditional models of education which focus on absorbing and memorising information. The authors suggest that AI, like many earlier communications technologies, is forcing a rethink ...

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease in cosmic rays above 3 PeV, giving it an unusual knee-like shape. The cause of the "knee" has remained unclear since its discovery nearly 70 years ago. Scientists have speculated that it is linked to the acceleration limit of the astrophysical sources of cosmic rays and reflects the transition of the cosmic ray energy spectrum from one power-law distribution to another.  Now, however, two recent studies—published in National ...

Researchers led by Keiya Hirashima at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan, with colleagues from The University of Tokyo and Universitat de Barcelona in Spain, have successfully performed the world’s first Milky Way simulation that accurately represents more than 100 billion individual stars over the course of 10 thousand years. This feat was accomplished by combining artificial intelligence (AI) with numerical simulations. Not only does the simulation represent 100 times more individual stars than previous state-of-the-art models, but ...

Over 30 years in his lab at The Picower Institute for Learning and Memory at MIT, Picower Professor Earl K. Miller has studied how the brain’s cortex produces thought. On Nov. 15, in an invited presidential lecture at the Society for Neuroscience annual meeting, he will tell the audience what reams of experimental evidence have led him to propose: Cognition and consciousness emerge from the dynamic organization of the cortex produced by traveling brain waves performing analog computations. Analog computing is an old ...

SAN DIEGO -- Veterans with Gulf War Illness experienced significant improvement in migraine symptoms after following a diet low in glutamate, a component of flavor enhancing food additives commonly found in processed foods, according to new research presented by Georgetown University and American University scientists. Brain scans also revealed decreased cortical thickness in patients on the diet — providing evidence, for the first time, that the improvement in symptoms was linked to measurable changes in the brain.  The findings point to a potential low-cost ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have applied ideas from polymer physics to illuminate the mechanism behind a key pathology in Alzheimer's disease, the formation of fibrils of tau proteins. They showed that fibril formation is preceded by the birth of large protein clusters, mirroring the crystallization of polymers. Crucially, dissolving these clusters helped to prevent fibrils forming in solution. Their work signals a paradigm shift for the development of treatments for neurodegenerative ...

Ferroelectric materials are used in infrared cameras, medical ultrasounds, computer memory and actuators that turn electric properties into mechanical properties and vice-versa. Most of these essential materials, however, contain lead and can therefore be toxic.  “For the last 10 years, there has been a huge initiative all over the world to find ferroelectric materials that do not contain lead,” said Laurent Bellaiche, Distinguished Professor of physics at the University of Arkansas.  The atoms in a ferroelectric material can have more than one crystalline structure. Where two crystalline structures meet is ...

Body composition—including bones, muscles, and adipose compartments—constitutes a crucial imaging biomarker for cardiometabolic risk stratification, as supported by extensive evidence; however, conventional imaging quantification remains constrained by labor-intensive workflows and limited anatomical coverage, hindering scalable and comprehensive assessment. Meanwhile, existing deep-learning efforts have largely focused on abdominal fat compartments (e.g., VAT and SAT), overlooking critical tissues such as muscle, ...

UNIVERSTIY PARK, Pa. — Counties in Pennsylvania that contained or were near cultivated cropland had significantly higher melanoma rates compared to other regions, according to a new study led by scientists at Penn State. Researchers at Penn State Cancer Institute analyzed five years of cancer registry data, 2017 through 2021, and found that adults over the age of 50 living in a 15-county stretch of South Central Pennsylvania were 57% more likely to develop melanoma, the deadliest form of skin ...

ITHACA, N.Y. –  In the growing gig economy, where a company’s success depends on contractors whose schedules they can’t control, businesses often turn to bonuses to lure and retain these workers. But according to new Cornell-led research, bonuses can be a losing strategy for the stakeholders involved in platform operations. “Bonus Competition in the Gig Economy,” published in the journal Production and Operations Management, shows that not all bonuses are created equal, and the availability of labor dictates which type of bonus is more effective for firms. Fixed bonuses, also known as subsidies – given as part of the contract – ...

A joint research team from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) and Shandong University has for the first time identified crystalline hematite (α-Fe2O3) and maghemite (γ-Fe2O3) formed by a major impact event in lunar soil samples retrieved by China's Chang'e-6 mission from the South Pole–Aitken (SPA) Basin. This finding, published in Science Advances on November 14, provides direct sample-based evidence of highly oxidized materials on the lunar surface. Redox reactions are a fundamental component of planetary formation and evolution. ...

CHAPEL HILL, NC — A study out of the University of North Carolina at Chapel Hill has unveiled new insights into the inflammatory processes behind periodontitis, a common and debilitating gum disease. Research conducted by UNC Adams School of Dentistry’s Julie Marchesan, DDS, PhD, and UNC School of Medicine’s Jenny Y. Ting, PhD, found that a part of the immune system called the inflammasome plays a key role in disease development, and that blocking this system prevents bone resorption only in males. The study, published in the journal Proceedings of the National Academy of Sciences, suggests developing treatments specifically for male patients can have benefits and prompted ...

Researchers from Stockholm University have – for the first time ever – managed to successfully isolate and sequence RNA molecules from Ice Age woolly mammoths. These RNA sequences are the oldest ever recovered and come from mammoth tissue preserved in the Siberian permafrost for nearly 40,000 years. The study, published in the journal Cell, shows that not only DNA and proteins, but also RNA, can be preserved for very long periods of time, and provide new insights into the biology of species that have long since become extinct. “With RNA, we can obtain direct evidence of which genes are ‘turned ...

In season three of the hit television series The White Lotus, the character Victoria Ratliff takes the prescription anti-anxiety medication lorazepam to help with her social anxiety and inability to sleep. Her casual usage of the powerful benzodiazepine — often in combination with white wine — leads to her becoming visibly loopy, slurring her words, and falling asleep at dinner. A recent study led by researchers at University of California San Diego has found that the show's portrayal of lorazepam use was associated with a surge in Google searches for the medication, including queries related to acquiring it online. The findings suggest that the show generated 1.6 million ...

A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping - the act of measurement itself. In a study published today (14 Nov) in Physical Review Letters, scientists demonstrate that the energy cost of reading a quantum clock far outweighs the cost of running it, with implications for the design of future quantum technologies. Clocks, whether pendulums or atomic oscillators, rely on irreversible processes to mark the passage of time. At the quantum scale, where such processes are weak or nearly absent, timekeeping becomes much more ...

Hypertension impairs blood vessels, neurons and white matter in the brain well before the condition causes a measurable rise in blood pressure, according to a new preclinical study from Weill Cornell Medicine investigators. The changes help explain why hypertension is a major risk factor for developing cognitive disorders, such as vascular cognitive impairment and Alzheimer’s disease. The preclinical findings, published Nov. 14 in Neuron, reveal that hypertension may induce early gene expression changes in individual brain cells that could interfere with thinking and memory. The findings may lead to medications that ...
