A major new study suggests that age-related changes in the uterus may contribute to poor pregnancy outcomes, with women over 49 having lower live birth rates and higher risk of miscarriage despite donor egg treatment. The findings, presented today at the 42nd annual meeting of the European Society for Human Reproduction and Embryology (ESHRE), challenge the assumption that donor eggs can completely ‘reset’ the reproductive clock by eliminating the effects of aging on reproductive function. In recent decades, social, economic, and technological changes have steadily increased the age at which mothers give birth. Age-related decline in fertility has traditionally been…

Enterotoxigenic Escherichia coli and Staphylococcus ruber It is responsible for hundreds of millions of infections worldwide each year and remains the leading cause of fatal diarrheal diseases, especially in children. Despite decades of research, scientists have yet to develop an effective vaccine against either pathogen. One major challenge is that the characteristics of the bacteria that vaccines typically target vary widely between strains. Now, researchers at Washington University School of Medicine in St. Louis have identified a common biological vulnerability to these dangerous gut bacteria, raising the possibility of a single vaccine that protects against both. The WashU Medicine team,…

A new meta-analysis suggests that allergies do not broadly protect against cancer, and that asthma and regional differences form small but important risk signals. Research: Association between allergies and cancer incidence: A systematic review and meta-analysis. Image credit: Belhadef.nabil / Shutterstock In a recent press research article published in the journal scientific reporta group of researchers used cohort-based evidence from multiple countries to assess the association between allergic disease and subsequent cancer development. Can a condition as common as allergies influence the likelihood of developing cancer?While an estimated 10% to 30% of the world’s population experiences allergic diseases, cancer remains…

Researchers have built a lightweight AI pipeline that could help more accurately identify upper airway obstruction by converting snoring sounds into time-frequency images, but real-world clinical trials remain the next hurdle. Research: Classification of snoring by deep time-frequency features. Image credit: Kleber Cordeiro / Shutterstock In the Journal’s recent “Press Articles” scientific reportresearchers proposed a heterogeneous integration framework for snoring source classification. Snoring is the main symptom associated with obstructive sleep apnea and is caused by obstruction or vibration of upper airway structures such as the epiglottis, base of the tongue, lateral oropharyngeal walls, and soft palate. The anatomical cause…

MALIDI, Kenya (AP) — The unfinished restaurant is still just concrete walls and wooden beams. While her daughter sweeps away the last pile of sand, Nur Mohammed, 54, instructs the women as they hang decorative fishing nets. In the coming days, a beachside restaurant on Kenya’s Indian Ocean coast will open, offering another way to earn a living.”For us women, this is hope,” Mohamed said. She spent most of her life as one of the few fishermen in Malindi, a town northeast of the port city of Mombasa. “It will help support the many families who have relied on the…

While swiping may not undermine overall well-being, a new review found that the strongest links cluster around compulsive use, pressure on appearance, and body-related vulnerability. Research: A systematic review and meta-analysis of the correlates of swipe-based dating app use and mental health. Image credit: r.classen / Shutterstock In a recent systematic review and meta-analysis published in the journal communication psychologyResearchers synthesized data from 27 peer-reviewed studies with 21,263 participants to assess the mental health correlates of swipe-based dating apps. Findings reveal small to moderate global associations between dating app use and negative psychological outcomes. Want to read it later? Click…

A surprising discovery on a small island in the Baltic Sea is changing the way scientists think about the relationship between ancient humans and wolves. Researchers have identified wolf fossils on the Swedish island of Stra Karsø that date back approximately 3,000 to 5,000 years. The discovery is notable because the island is isolated and has no native land mammals. The wolves could not have reached the island on their own, leading researchers to conclude that humans must have brought them there. This study Proceedings of the National Academy of Sciencescarried out by scientists from the Francis Crick Institute, Stockholm…

Scientists have identified evidence of a previously unknown process that may explain how brain cells die in Alzheimer’s disease and frontotemporal dementia (FTD). The discovery, centered around a mechanism known as karyoptosis, could point researchers to new ways to slow the progression of these devastating conditions. Many neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS), Alzheimer’s disease, and FTD, are characterized by the accumulation of harmful proteins within neurons. Over time, these nerve cells die, causing memory loss and other symptoms. Although scientists have long known about several forms of cell death, including apoptosis, those mechanisms never fully explained the…

New research suggests that the way poll questions are phrased can blur the line between association and causation, especially when public health claims are politically charged. Research: Support for increased risk claims regarding Tylenol and autism may not reflect a causal relationship. Image credit: Chemical Industry / Shutterstock Recent reports published in magazines scientific report suggest that linguistic frameworks can influence the interpretation of scientific claims, with the clearest wording effects observed among participants with a university degree. Researchers investigated whether differences in the wording of recent poll questions about the association between Tylenol (acetaminophen) use during pregnancy and autism…

When you close your eyes in bed tonight, something strange will happen to you. Your mind passes from ordinary thoughts to dreams, but it is impossible to say exactly when it happened. We tend to imagine that there is a clear line between when we are asleep and when we are awake. I think when I’m awake. We dream when we are asleep. But our research, published in Cell Reports, shows that this boundary is more porous than we imagined. You can dream before you fall asleep and plan your day after you fall asleep. From thoughts to dreams and…
