Pregnancy loss may occur in as many as 25% of all pregnancies. Most of these losses occur in the first trimester, and about half are caused by genetic or chromosomal issues. When pregnancy loss occurs three or more times, the losses are referred to as recurrent. Often the cause of recurrent pregnancy loss is difficult to uncover and remains unknown to those experiencing it. However, two new studies presented at the Association for Molecular Pathology (AMP) 2025 Annual Meeting & Expo, taking place Nov. 11–15 in Boston, provide some answers. These studies both utilized a cutting-edge technique known as optical ...

ROCKVILLE, Md. —  Acute myeloid leukemia (AML) is the most common type of acute leukemia in adults. It develops quickly, with symptoms often coming on within just a few weeks, and requires urgent treatment. Despite advances, many patients relapse and outcomes can be poor —  making faster, more accurate diagnostic tools critical to patient survival. Breakthrough studies in hematopathology — including advances in genetic testing, relapse prediction and detection of hidden, disease-defining gene fusions in AML  — will be presented at the Association for Molecular Pathology (AMP) 2025 Annual Meeting & Expo, taking place Nov. 11–15 ...

Across the United States, children spend more than 1,100 hours in school each year – time that shapes not only their academic success but also their emotional and social growth. Yet, for many students, the school environment can also be a source of anxiety and apprehension. School counselors play a pivotal role in addressing these challenges through evidence-based, comprehensive guidance programs. Addressing this critical need, researchers from Florida Atlantic University’s Department of Counselor ...

Scientists at The Hospital for Sick Children (SickKids) have revealed a previously overlooked layer of genetic variation that could help explain why people experience disease differently, and why some treatments work better for certain populations.  Tandem repeats are repeated sections of a DNA strand that make up about seven per cent of the human genome. The likelihood of those tandem repeats causing errors in gene function increases each time they repeat, and they are known to cause conditions like ...

Melanoma remains one of the hardest skin cancers to diagnose because it often mimics harmless moles or lesions. While most artificial intelligence (AI) tools rely on dermoscopic images alone, they often overlook crucial patient information (like age, gender, or where on the body the lesion appears) that can improve diagnostic accuracy. This highlights the importance of multimodal fusion models that can enable high precision diagnosis. To bridge that gap, Professor Gwangill Jeon from the Department ...

Glioblastoma—the most aggressive form of brain cancer—remains one of medicine’s biggest challenges. Despite surgery, radiotherapy, and chemotherapy, most patients survive only about a year after diagnosis. However, a new discovery might change how doctors understand and monitor this deadly disease. Specifically, the study focused on isocitrate dehydrogenase (IDH) wild-type glioblastoma, the most common and rapidly growing form of the tumor, known for its poor prognosis and limited treatment options.   In a study published online on October 11, 2025, in Neuro-Oncology, ...

The most common technique used for closing the uterus after a cesarean delivery causes so many long-term complications that it’s time to question its use. That’s the conclusion reached by two world-renowned specialists in obstetrics and gynecology in an article published in a special issue of the American Journal of Obstetrics & Gynecology on cesarean delivery. The authors argue in favor of replacing the current approach with a closure technique that respects the natural anatomical structure of the uterus. The authors, Dr Emmanuel Bujold, professor at Université ...

Researchers Kohki Horie, Keiichiro Toda, Takuma Nakamura, and Takuro Ideguchi of the University of Tokyo have built a microscope that can detect a signal over an intensity range fourteen times wider than conventional microscopes. Moreover, the observations are made label-free, that is, without the use of additional dyes. This means the method is gentle on cells and adequate for long-term observations, holding potential for testing and quality control applications in the pharmaceutical and biotechnology industries. The findings are published in the journal Nature Communications. Microscopes have ...

ANN ARBOR—For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary enough to slip through the notice of selection. Now, a University of Michigan study has flipped that theory on its head.  In the process of evolution, mutations occur which can then become fixed, meaning that every individual in the population carries that mutation. A longstanding theory, called the Neutral Theory of Molecular Evolution, posits that most genetic mutations that are fixed are neutral. Bad mutations ...

Tensor operations are the kind of arithmetic that form the backbone of nearly all modern technologies, especially artificial intelligence, yet they extend beyond the simple maths we’re familiar with. Imagine the mathematics behind rotating, slicing, or rearranging a Rubik’s cube along multiple dimensions. While humans and classical computers must perform these operations step by step, light can do them all at once. Today, every task in AI, from image recognition to natural language processing, relies on tensor operations. However, the explosion of ...

Mangrove ecosystems rank among the most efficient "blue carbon" systems on Earth, capable of absorbing and storing vast quantities of atmospheric carbon dioxide (CO2). However, mangroves also release methane (CH4), a potent greenhouse gas, potentially offsetting a portion of their climate mitigation benefits. While prior research has focused primarily on methane emissions from mangrove soils and water surfaces, the role of tree stems as an emission pathway and its significance for global blue carbon accounting have remained largely unexamined. In a new study, researchers from the South China Botanical Garden of the Chinese Academy of Sciences conducted a global-scale ...

Food brings people together. It serves as a tool to communicate political stances, to cultivate cross-cultural comprehension or, if necessary, create tensions. Menus can reflect these intentions by using food to create specific psychological effects and convey symbolic messages. But how exactly is it done? Now, researchers in Portugal have examined menus from diplomatic dinners, state banquets, and receptions hosted over the 20th and 21st centuries to find out how meals reflected and shaped Portuguese foreign policy and ...

As data theft and counterfeiting grow ever more sophisticated, cryptography demands devices that are miniature, reconfigurable and almost impossible to reverse-engineer. Now researchers from the Shenyang Institute of Automation (CAS), Shanghai University and City University of Hong Kong—led by Prof. Haibo Yu and Prof. Wen Jung Li—have created a micro-dynamic multiple encryption device (μ-DMED) built from coumarin-based metamaterials that can hide, rewrite and store multilevel information under different light fields. The work establishes a new paradigm for on-chip, high-security optical encryption. Why μ-DMED Matters All-Optical ...

Professor Wen-Bo Liu's research group at Wuhan University reported a nickel-catalyzed regioselective hydrogen metallization/5-exo-trig cyclization reaction. Using β-propargylcyclobutanone as a starting material, multi-substituted bicyclo[2.1.1]hexanol can be synthesized in one step, followed by skeletal rearrangement to yield 1,2,4-trisubstituted bicyclo[2.1.1]hexanone. This structure can be used for diverse derivatization reactions. DFT computational studies elucidated the crucial role of carbonyl coordination in regioselectivity control. This research provides a new method for obtaining structurally ...

LA JOLLA, CA—When labor begins, the uterus must coordinate rhythmic, well-timed contractions to deliver the baby safely. While hormones such as progesterone and oxytocin are key contributors to that process, scientists have long suspected that physical forces—in this case, the stretching and pressure that accompany pregnancy and delivery—also play a role. Now, a new study from Scripps Research published in Science on November 13, 2025, reveals how the uterus senses and responds to those forces at a molecular level. The findings could help scientists better understand the biological roots of conditions such as stalled labor and preterm birth, guiding ...

There are more candidates on the waitlist for a liver transplant than there are available organs, yet about half the time a match is found with a donor who dies after cardiac arrest following the removal of life support, the transplant must be canceled. For this type of organ donation, called donation after circulatory death, the time between the removal of life support and death must not exceed 30 to 45 minutes, or the surgeons will often reject the liver because of the increased risk of complications to the recipient. Now, Stanford Medicine researchers have developed a machine learning-based ...

Antibiotic resistance is widely recognized as one of the most urgent public health challenges of the twenty first century. Now, a new study shows that even very small amounts of antibiotics that commonly appear in soil, rivers, wastewater, and agricultural runoff may significantly accelerate the spread of antibiotic resistance genes among bacteria. The research, published in Biocontaminant, investigates how four typical antibiotics found in the environment influence both vertical and horizontal gene transfer, the two major pathways through which bacteria pass on resistance. The team examined tetracycline, ...
