Using artificial intelligence (AI), researchers found that image-based breast cancer risk scores from screening mammograms change over time and differ between women who develop cancer and those who do not, opening the door to a new era of dynamic breast cancer risk assessment.新しい研究は本日、 RadiologyJournal of the Radiological Society of North America (RSNA). Deep learning models can now generate breast cancer risk scores directly from screening mammograms, using the entire image rather than limited, predetermined features such as density. These models perform better than traditional risk models or breast density alone in estimating a woman’s 5-year breast cancer risk. Most women…

Triple-negative breast cancer (TNBC) is highly aggressive and difficult to treat. But a new paper by scientists at the Hackensack Meridian Center for Discovery and Innovation (CDI) and colleagues at Georgetown University’s Lombardi Comprehensive Cancer Center says the role of adipose tissue in cancer spread could help point to new understanding and treatments. Scientists have now demonstrated that fat tissue can be hijacked by tumor cells to launch itself and use adipomes, tiny extracellular vesicles released by fat tissue, to spread further into the body, outward from the breast and outward to other organs. This discovery could provide new strategies…

“There is a very urgent need to find ways to reduce the emissions that these backup generators emit into nearby communities,” said Associate Professor Damien Pitt, who conducted the research. To date, the operating rates of these backup generators are far below the operating rates allowed by Virginia law. “The really big problem is that the total amount of emissions allowed is 10 to 20 It’s many times larger than what’s currently being released,” Pitt said. That’s why Rep. John McAuliffe, a Democrat whose district in Northern Virginia is on the edge of the so-called data center array, introduced a…

The Ross procedure is a highly specialized option for aortic valve replacement, with long-term durability and excellent outcomes in a wide range of adult patients with aortic valvular disease. These are the results of a new groundbreaking study led by Ismail El Hammamsy, MD, world-renowned Mount Sinai cardiac surgeon and chief of aortic surgery at the Mount Sinai Health System, and published June 23 in the journal Ismail El Hammamsy, MD. Journal of the American College of Cardiology (Jack). This landmark publication represents the largest North American study ever conducted on the Ross procedure. The findings from this contemporary cohort…

When H5N1 avian influenza began infecting dairy cows in the United States in early 2024, veterinarians struggled to pinpoint the cause. The virus has been difficult to recognize because it behaves very differently in cattle than in other mammals. Rather than primarily infecting the lungs, H5N1 causes severe infections in the breasts, but has little effect on the respiratory system. Now, researchers at the University of Pittsburgh School of Public Health have uncovered the biological reason behind this unusual pattern. Their findings were; scientific progressfor the first time we have a detailed explanation of why avian influenza took such an…

Researchers have developed a chip-based metasurface biosensor that can detect traumatic brain injury (TBI) biomarkers at extremely low levels. With further development, this technology could one day allow doctors to quickly diagnose the aftermath of a head injury, guide treatment, and provide early warning of complications as they occur. Metasurfaces are ultra-thin materials patterned with tiny features that can manipulate light in ways that traditional lenses cannot. Coating the metasurface with antibodies that bind to specific target molecules allows those molecules to be detected using light. Although several biomarkers have been validated as indicators of traumatic brain injury, current…

The environment that young zebrafish experience influences both the shape and electrical activity of eye neurons, which in turn influences their subsequent behavior. Neuroscientists at King’s College London studied five-day-old fish to investigate whether the visual features of the environment in which they grew up influenced the development of eye cells. The study, published in Neuron, found that fish that grew up surrounded by horizontal stripes developed neurons with different shapes and responses compared to fish that grew up surrounded by vertical stripes. Using a virtual reality behavioral test developed in collaboration with the University of Konstanz, the researchers showed…

Forced by disparities in breast cancer outcomes, the Keck School of Medicine of the University of Southern California, School of Population and Public Health, and Novartis have joined forces in a pioneering collaboration to support underserved communities in Los Angeles County with the goal of removing barriers to screening and access. We are excited to collaborate with Novartis towards our shared goal of identifying key drivers of health disparities and understanding how to improve access. ” Dr. Chanita Hughes Hulbert, Associate Director for Cancer Health Disparities and Distinguished Professor of Population and Public Health Sciences at the University…

A new systematic review from the Columbia University School of Nursing finds that access to fertility preservation (FP) care remains limited and unequal for girls and young women with cancer. The research paper, “Fertility preservation access for female adolescents and young adults with cancer: a systematic review,” was published in Cancer on June 23, 2026. More than 85,000 adolescents and young adults (AYA) between the ages of 15 and 39 are diagnosed with cancer each year in the United States. After diagnosis, AYAs face an increased risk of long-term treatment-related effects such as cardiotoxicity, ototoxicity, and infertility. Among these, infertility…

Kombucha has skyrocketed in popularity around the world in recent years, becoming one of the most widely consumed fermented beverages. Many people choose it for its unique flavor, but researchers are taking a closer look at what happens inside the drink during fermentation and how its ingredients affect its properties. Scientists from the Wrocław University of Environmental and Life Sciences and the Wrocław Medical University (Associate Professor Helena Moreira, PhD; Associate Professor Eva Barg, MSc) set out to investigate one important question: Does the type of tea used to make kombucha affect the final product? Their findings revealed a much…
