To the point Power relationships between female and male gorillas: They are less strictly male-biased than previously thought. Females can overpower males despite the extreme male-biases in size and strength. Revisiting traditional gender narratives: Females that overpower males have priority of access to food over these males, challenging the traditional narrative that females and males compete over different resources (females  over food and males over females). Over 50 years ago, the idea that males had universal ...

About The Study: In this modeling study, economic favorability of COVID-19 vaccination varied by age. Cost-effectiveness results for individuals in the 2 older age groups were favorable and generally robust to changes in parameter inputs, while results for the younger age group were sensitive to parameter input changes. As the evidence base for COVID-19 vaccination and burden of illness evolves, it may be important to continue to update and revise the economic evaluation of vaccination. The Advisory Committee on Immunization Practices considered these results in its decision to recommend vaccination with the 2023 to 2024 COVID-19 mRNA ...

About The Study: Stratified analyses in this study revealed that prediabetes was significantly associated with mortality only among younger adults (ages 20-54), highlighting the importance of age-specific interventions. Lifestyle behaviors, limited health care access, and life stage challenges may contribute to the increased mortality risk in younger adults. Early-onset health problems in this group may also reflect stronger genetic predispositions, leading to more rapid disease progression and more severe health outcomes. These findings underscore ...

The Perito Moreno Glacier in Argentina — often described as one of the most stable glaciers in Patagonia — is retreating far more rapidly than previously thought, according to a paper in Communications Earth & Environment. The results show that, over the last few years, the glacier has retreated by as much as 800 metres in some areas, and that it may collapse and retreat by several kilometres in the near future. The Perito Moreno Glacier is a 30-kilometre-long glacier in the Argentine Patagonia, fed by the Southern Patagonian Ice Field in the Andes and terminating in ...

To the point Stable genetic ancestry: Despite significant cultural changes, populations in the Southern Caucasus have maintained remarkably constant genetic ancestry for over 5,000 years. Genetic contributions during the Bronze Age: Although local genetic continuity was predominant, there were partial genetic contributions from the Eurasian Steppe and from Anatolia during the Bronze Age. Cultural influences: Practices such as cranial deformation were adopted primarily through cultural influences, rather than solely through migration. New insights into the Southern Caucasus region: This research highlights the Southern Caucasus as ...

Quick facts: Clinical research, 752 individuals with type 2 diabetes, quantitative study, DNA methylation as a way to identify epigenetic biomarkers in blood. People with type 2 diabetes are up to four times more likely to have heart attacks, strokes, anginas and other coronary heart diseases than healthy people. Therefore, biomarkers that help us understand which individuals are at risk of being affected are needed. A research team led from Lund University in Sweden, followed 752 people who, when the study started, were newly diagnosed with type 2 diabetes. ...

University of Virginia School of Medicine scientists are tapping the power of artificial intelligence to enhance and accelerate treatment for glioblastoma, the deadliest brain cancer. UVA researcher Bijoy Kundu, PhD, and colleagues are developing an AI imaging approach to distinguish between tumor progression and brain changes caused by tumor treatment. It now can take months to make that distinction, leaving doctors uncertain if the tumor is growing and stalling important care decisions. Kundu’s AI approach is already outperforming ...

Both for research and medical purposes, researchers have spent decades pushing the limits of microscopy to produce ever deeper and sharper images of brain activity, not only in the cortex but also in regions underneath such as the hippocampus.

A new framework for diagnosis The 2024 European clinical practice guidelines introduce a pivotal terminology shift, replacing NAFLD (non-alcoholic fatty liver disease) with MASLD (metabolic dysfunction-associated steatotic liver disease) and NASH with MASH (metabolic dysfunction-associated steatohepatitis). This renaming is not just semantic—it provides a pathophysiologically grounded, inclusive classification system based on the presence of hepatic steatosis and at least one cardiometabolic risk factor. Importantly, MASLD is now grouped ...

Background and objectives The incidence of early-onset pancreatic cancer (EOPC) is rising, yet optimal treatment strategies remain unclear. While adjuvant chemotherapy (ACT) has shown survival benefits in pancreatic ductal adenocarcinoma, its specific role in EOPC patients following neoadjuvant chemotherapy (NACT) and surgery remains underexplored. This study aimed to assess the clinical benefit of ACT in EOPC patients after NACT. Methods This retrospective cohort study analyzed pancreatic ductal adenocarcinoma patients from the SEER database (2006–2019) who received NACT followed by curative resection. Propensity ...

COLUMBUS, Ohio – A new study combines eye tracking and artificial intelligence to identify the exact moments in an educational video that matter for learning in children.   The study could also predict how much children understood from the video based on their eye movements while they were watching it.   The research is preliminary, but it provides promise for some exciting breakthroughs in video education, said Jason Coronel, lead author of the study and associate professor of communication at The Ohio State University.   “Our ultimate goal is to build ...

What are the limits of quantum physics? This is a question that has been researched around the world for decades. If we want to make the properties of the quantum world technically usable, we need to understand whether objects that are significantly larger than atoms and molecules can also exhibit quantum phenomena. For example, small glass spheres with a diameter of one hundred nanometres can be examined – still over a thousand times smaller than a grain of sand, but huge by quantum standards. For years, attempts have been made to show the extent to which such spheres ...

Japanese rice fish, known as medaka, are small, easy to breed, and reproduce daily, making them widely used as model organisms around the world. Until now, medaka research has mainly occurred in labs where environmental conditions and study observations are easily controlled. Unnatural environmental settings such as these bring into question the accuracy of previous behavioral findings. Therefore, this study is important for answering the fundamental question of whether the behavior of animals observed in laboratories is the same as in their natural environments. A ...

Chemistry and physics are combining forces at Columbia, and it’s leaving everyone frustrated—in a good way. New work, published today in Nature Physics, describes a new two-dimensional material capable of complex quantum behaviors that arise from its underlying chemistry, rather than its atomic structure.  “It’s a classic Columbia story—multiple groups in physics and chemistry came together to work on this new material, and we found exciting new results about how electrons move,” said Aravind Devarakonda, an applied physicist at Columbia Engineering.  The material, Pd5AlI2, ...

426,016. That’s how many packages of illegal medicines EU agencies confiscated during an eight-month operation in 2024. During the operation, they managed to find counterfeit medicines worth 11.1 million euros. And it’s an increasingly bigger problem. “Pharmaceutical crime is a growing threat in the EU,” Europol stated earlier this year. Fortunately, a new weapon against pharmaceutical counterfeiting may be on the way. Researchers from the University of Copenhagen and Stanford University have shown in a new study that it is possible to distinguish seemingly identical medicines at the molecular level – both across ...

Many animals, including humans, can flexibly modulate their responsiveness to sounds according to different situations. This ability allows them to optimize the use of their limited brain resources by prioritizing the processing of critical information at any given moment. In line with this idea, a research team at Nagoya University in Japan has demonstrated that when female fruit flies are eager to mate, dopaminergic signals can influence their sensitivity to sounds, including courtship sounds from males, which are an essential source of information for species reproduction. "We believe that this finding is the first step toward understanding the neural mechanisms that underlie ...

Large ocean animals can be protected throughout much of their lifecycle by huge Marine Protected Areas (MPAs), new research shows. Scientists tracked sea turtles, manta rays and seabirds – all of which travel far and wide to forage, breed and migrate – in the Chagos Archipelago MPA in the Indian Ocean. In total, 95% of tracking locations were recorded inside the MPA’s 640,000 square kilometre area – suggesting it is large enough to protect these wandering animals. The study – by a team including Exeter and Heriot-Watt universities and ZSL – also assessed the impact of a smaller 100,000 square kilometre MPA and found seabirds would be less well protected ...

Up to 60% of women experience some fear about giving birth, especially for the first time, but a new study shows why some women are more likely to stay calm and confident in the lead-up to childbirth. In a global first, researchers from Robert Gordon University in Scotland and the University of South Australia (UniSA) investigated the factors that help ease childbirth fears, rather than stoke them. They surveyed 88 pregnant women in their third trimester before attending antenatal classes in north-east ...
