DENVER/Aug. 3, 2023 – A newly funded study will evaluate the potential of a cancer drug to control tumor growth and improve outcomes for dogs with histiocytic sarcoma, an aggressive and typically fatal canine cancer. The multi-center clinical trial is being conducted at Michigan State University, University of Florida, University of Wisconsin and Virginia Tech, and funded by the Bernese Mountain Dog Club of America through Morris Animal Foundation's Donor-Inspired Study program. Histiocytic sarcoma was ...

LA JOLLA, CA—Gastrointestinal and digestive issues impact roughly 3 million people across the United States alone, and that number is growing. A new study from Scripps Research scientists shows how sensory neurons control our gastrointestinal tracts—critical information that could shape our understanding of related diseases and disorders.      The study, published in the journal Cell on Aug. 3rd, 2023, used a combination of human clinical data and animal models to reveal that the receptor PIEZO2 controls gastrointestinal transit through the stomach, small intestine, and colon by sensing the presence of food and slowing the rate of gut motility accordingly. These ...

Immune system T cells that should be able to kill cancer cells become dysfunctional or “exhausted” within hours of encountering a tumor, according to a study reported Aug. 3 in Nature Immunology. The surprising findings have implications for cancer immunotherapies that aim to harness the tumor-killing power of T cells, and they challenge existing ideas about how T cells become exhausted, said Mary Philip, MD, PhD, assistant professor of Medicine in the Division of Hematology and Oncology ...

DURHAM, N.C. – Four years ago, a report that a common species of fungus might fuel pancreatic cancer offered a promising new view of the deadly disease.   But in working to validate the finding, Duke Health researchers have found no such association. In a study appearing online Aug. 3 in the journal Nature, the Duke researchers conducted a multi-pronged analysis of data from the earlier study and found no link between the pancreatic microbiome and the development of pancreatic cancer.   “We were intrigued by the original finding, as were ...

Dopamine: It’s not just for rewards anymore. In a new Northwestern University-led study, researchers identified and recorded from three genetic subtypes of dopamine neurons in the midbrain region of a mouse model.  Although there is a long-standing, common assumption that most — if not all — dopamine neurons solely respond to rewards or reward-predicting cues, the researchers instead discovered that one genetic subtype fires when the body moves. And, even more surprisingly, these neurons curiously do not respond to rewards at all. Not only ...

RESEARCH SUMMARY Study Title: Mammalian SWI/SNF chromatin remodeling complexes promote tyrosine kinase inhibitor resistance in EGFR-mutant lung cancer Publication: Cancer Cell Dana-Farber Cancer Institute Senior and Lead Authors: Cigall Kadoch, PhD; Claudia Gentile, PhD; Akshay Sankar Study Summary:  When lung cancers driven by mutations in the EGFR gene become resistant to osimertinib or other targeted therapies, epigenetic changes, rather than genetic changes, are often to blame. In a new study in Cancer Cell, researchers at the Dana-Farber Cancer Institute and Yale Cancer Center show that the main source of these changes are ...

About 55 million years ago, the Atlantic Ocean was born. Until then, Europe and America were connected. As the continents began to move apart, the Earth’s crust between them ruptured, releasing large volumes of magma. This rift volcanism has led to the formation of large igneous provinces (LIPs) in several places around the world. One such LIP was formed between Greenland and Europe and now lies several kilometres below the ocean surface. An international drilling campaign led by Christian Berndt from the GEOMAR ...

NASA's James Webb Space Telescope (JWST) has recorded breath-taking new images of the iconic Ring Nebula, also known as Messier 57.   The images, released today by an international team of astronomers led by Professor Mike Barlow (UCL, UK) and Dr Nick Cox (ACRI-ST, France), with Professor Albert Zijlstra of The University of Manchester, showcase the nebula's intricate and ethereal beauty in unprecedented detail, providing scientists and the public with a mesmerizing view of this celestial wonder.  For many sky enthusiasts, the Ring Nebula is a well-known object that is visible all summer long and is located in the constellation ...

SKIN CANCER-RELATED MUTATIONS HIGHER IN THE UK THAN SINGAPORE A new study has shown how, on average, people in the UK have facial skin that is far more DNA damaged from the sun than people in Singapore, explaining the far higher risk of developing the most common skin cancers in the UK. This study looked at keratinocyte cancers - basal and squamous cell carcinomas - rather than melanoma, a rarer and sometimes fatal form of skin cancer, finding Northern European skin types in the UK were less able to protect themselves from UV damage. Researchers from the Wellcome Sanger Institute and their collaborators at ...

UK researchers are calling on higher education institutes and research funders to adopt a new set of recommended actions to address the substantial under-representation of PhD students from ethnic minority backgrounds. Black, Asian and minority ethnic students have a markedly lower representation in postgraduate research compared with undergraduate or taught postgraduate study in the UK. For instance, in 2020/21, around 26.5% of UK undergraduates were from ethnic minority backgrounds, compared with around 19% for postgraduate students.  The ...

A joint research team from City University of Hong Kong (CityU) and collaborators recently developed a stable artificial photocatalytic system that is more efficient than natural photosynthesis. The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, a valuable fuel, very efficiently using light. This is a promising discovery, which could contribute to the goal of carbon neutrality. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy. In past decades, many scientists have tried to develop artificial photosynthesis processes to turn ...

Principal Investigator Professor Alessandro Tagliabue said: “To date we have not fully appreciated ...

Wnt signalling is a well-known mode of cell-to-cell communication in multicellular biological organisms. It involves the secretion of small Wnt glycoproteins, by signalling cells, that bind to receptor proteins in the membrane of receiving cells. This signal modifies proteins on the inside of these receiving cells to make cells grow, divide or differentiate. This mode of communication is fundamental in both normal and altered cellular development, such as in cancer and wound healing, and has remained in the limelight ...

A University of Ottawa-led research team has published rigorous new research that advances a quest to understand a puzzling – and heartbreaking – ultra-rare disease that’s found almost exclusively in boys. XLP-2 is a genetic X-linked lymphoproliferative disease first described in 2006. It typically has severe complications among patients who become infected with the Epstein-Barr virus, an exceedingly common virus that infects most people without problems in their teenage years or young adulthood. But when the few individuals with XLP-2 encounter the Epstein-Barr virus the experience is often fatal ...

About a third of the restaurants listed on iFood, the food delivery app most used by Brazilians, are “dark kitchens”, according to the first study of the topic conducted in Brazil, and one of only a few worldwide. An article on the study is published in the journal Food Research International. It has eight authors; the first three and the last are researchers at the State University of Campinas (UNICAMP) in São Paulo state. Defined in the article as delivery-only restaurants that have no direct contact with consumers, have no premises for local consumption and sell solely ...

WASHINGTON —On a hot summer day, white clothing feels cooler than other colors due to reflecting—not absorbing—sunlight. Other colors like blue or black, will undergo a heating effect as they absorb light. To circumvent this heating effect in colored cooling films, researchers drew inspiration from nanostructures in butterfly wings. The new films, which don’t absorb any light, could be used on the outside of buildings, vehicles and equipment to reduce the energy needed for cooling while preserving vivid color properties. “In buildings, large amounts of energy are used for cooling and ventilation, and running ...

The climate crisis is severely affecting marine ecosystems around the world and the Mediterranean is not an exception. Marine heat waves associated with this crisis are causing massive mortality events throughout the basin. Given this scenario, their correct definition and characterization become a key element in defining possible future scenarios. Now, a new study by the Institut de Ciències del Mar (ICM-CSIC) and the Institute of Marine Sciences of the National Research Council (CNR-ISMAR) has revealed how decoupling global warming trends affects the definition of marine heat waves characteristics. ...

Light affects living organisms in many different ways: for example, plants orient their growth direction towards the sun, while circadian rhythms in humans are controlled by daylight. These processes always involve photoreceptors, which are proteins that can sense different colours and intensities of light. 10,000-fold increase in enzymatic activity Now, researchers at Graz University of Technology (TU Graz) have deciphered the function of a highly efficient photoreceptor. Their findings have been published in the journal Science Advances. The research ...

The western U.S., particularly the Southwest, has experienced a notable increase in record-breaking high temperatures over recent decades, with recurring drought and heatwaves. These conditions have resulted in severe consequences for both human and nature systems, including dire water shortages, rampant wildfires, substantial agricultural losses, and increased human mortality. These regions, dominated by water-limited ecosystems, face exacerbated water stress due to more frequent and protracted droughts and heatwaves, which can profoundly impair ecosystem ...
