Mammography screening supported by artificial intelligence (AI) is a safe alternative to today’s conventional double reading by radiologists and can reduce heavy workloads for doctors. This has now been shown in an interim analysis of a prospective, randomised controlled trial, which addressed the clinical safety of using AI in mammography screening. The trial, led by researchers from Lund University in Sweden, has been published in The Lancet Oncology.  Each year around one million women in Sweden are called to mammography screening. Each screening examination is reviewed by two breast radiologists to ensure a high sensitivity, so called double reading. ...

Decades of research have left knowledge gaps about cells that regulate the immune system: Purdue and NIH Four decades of research have produced a vast pool of knowledge about regulatory T cells, a subset of our immune cells. Even so, scientists at Purdue University and the National Institutes of Health have identified 14 understudied T-reg proteins that merit increased attention for the molecular roles they play in disease onset. “Our lab studies the exact molecular mechanism underlying autoimmunity, infection and cancer,” said Majid Kazemian, associate professor of biochemistry in the College of Agriculture ...

The silver rice rat, an endangered species endemic to the Florida Keys, makes its home as close to the shoreline as possible for easy access to its low-tide marine species diet. It is this proximity to the water that prompted a team of scientists at the University of Florida to examine the rats’ movement in correlation with historical tidal data over 17 years. The sea level rose 0.142 meters between 2004 and 2021, and the researchers also found that the rats moved to higher ground. In fact, the rats ...

BOSTON – Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham health system, officially opened the Legorreta Center for Clinical Transplant Tolerance, the first-of-its kind center in the world dedicated to preventing organ rejection after transplant surgery without the use of lifelong immunosuppressive medications. Immunosuppressive medications prevent the immune system from rejecting a transplanted organ, but come with serious side effects, increasing the chance of infections and other illnesses like cancer, diabetes, and heart disease. The mission of the Legorreta Center is to eliminate these risks by eliminating ...

Abstract Research investigating social media use typically focus on late adolescents and young adults, despite a growing number of early adolescents, 93% to 97%—having at least one social media platform. Also, early adolescents are more likely to engage with newer sites, such as Snapchat and Instagram, than older platforms such as Facebook and Twitter. Given the evolving landscape of social media, the present study examines the impact of the use of various social media platforms, along with its moderating effects, on adolescents’ academic achievement, using a sample of N = 1,459 early adolescents. Results were such that, as frequency ...

AURORA, Colo. (July 31, 2023) – Researchers at the University of Colorado Anschutz Medical Campus have officially identified a central conduit to obesity: fructose. While fructose’s contribution to obesity is well-known, a study published today in Philosophical Transactions aggregates a large amount of work to make a full argument for how fructose drives obesity and diseases such as diabetes and fatty liver disease. “This is an in-depth review on a hypothesis that puts nature at the center of weight ...

In 2016, recognizing that lack of research in female animals was hampering the success of treatments for mood disorders, the National Institutes of Health (NIH) changed its policy for basic research to include sex as a biological variable for basic research, a move that triggered an explosion of research into sex differences. “Building a strong unbiased foundation of literature will help uncover more effective and sex-specific biomarkers for depression onset and target better treatment,” said Georgia Hodes, assistant professor in the School of Neuroscience, part of the Virginia Tech College of Science. Hodes and co-author Dawson Kropp, a Ph.D. ...

Carbon dioxide levels in Earth’s atmosphere — and, consequently, ocean temperatures — are rising. How high and how fast ocean temperatures can rise can be learned from temperature measurements of ancient oceans. At the same time, energy exploration also relies on knowing the thermal history of oil and gas source rocks, which is often difficult to determine. One of the most promising techniques for measuring ancient ocean temperatures and basin thermal histories relies on the co-enrichment of rare heavy oxygen and heavy carbon ...

Losing the ability to see clearly, and losing the ability to think or remember clearly, are two of the most dreaded, and preventable, health issues associated with getting older. Now, a new study lends further weight to the idea that vision problems and dementia are linked.  In a sample of nearly 3,000 older adults who took vision tests and cognitive tests during home visits, the risk of dementia was much higher among those with eyesight problems – including those who weren’t able ...

“We have discussed in detail the clinical implications of ER in avoiding overtreatment and undertreatment in DCIS.” BUFFALO, NY- August 1, 2023 – A new editorial paper was published in Oncotarget's Volume 14 on July 20, 2023, entitled, “Multiclonality of ER expression in DCIS – Implications for clinical practice and future research.” Estrogen receptor (ER) expression is not routinely evaluated in ductal carcinoma in situ (DCIS). This may be because the prognostic role of ER in DCIS was unclear until the UK/ ANZ DCIS trial in 2021 showed that lack of ER expression in DCIS was associated with a greater than 3-fold risk of ipsilateral recurrence. This ...

The public funding of science is responsible for many of the biomedical and other scientific breakthroughs on which our lives depend. However, the process through which funding decisions are made, the peer review of grant proposals, has been historically understudied, and current approaches can lead to undesirable outcomes.
