CHICAGO—Not having reliable access to food has a significant relationship with metabolic syndrome, a condition that increases risk for diseases such as diabetes and heart disease, in Latinx females of reproductive age, according to a study presented Friday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill. “Because of the significant association identified between low food security and metabolic syndrome in reproductive-aged Latinx females, there is potential to reduce cardiovascular, metabolic and reproductive adverse outcomes through improved ...

CHICAGO—Body mass index (BMI) is not a complete measure of metabolic health, and a high proportion of U.S. adults with normal BMI still have obesity, according to research being presented Friday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill. The latest research highlights the importance of including what percentage of the body is fat, muscle, bone, and water, and how much fat is in the abdomen vs. the thighs to fully understand drivers for cardio-metabolic disease. “We show that there are racial/ethnic differences in body ...

Breast cancer medications, called aromatase inhibitors, may lessen the effect of weight loss drugs, according to a new study being presented Friday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill. The study found that weight loss medications are less effective in breast cancer survivors who are treated with aromatase inhibitors, compared with women without a history of breast cancer who are not taking aromatase inhibitors. Aromatase inhibitors are used to treat some types of breast cancer or to keep it from coming back. They may also be used to help prevent breast cancer in some women who are ...

Children and teenagers who use continuous glucose monitors (CGM) to manage diabetes often fail to use the appropriate alarm settings to alert to dangerously low or harmful high blood sugar levels, according to a study being presented Thursday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill. This variability makes the monitors less useful in tracking glucose levels. Children with diabetes employ a large range of CGM alarm settings and cutoffs, many of which differ significantly from recommended values. ...

To enjoy the scent of morning coffee and freshly baked cookies or to perceive the warning smell of something burning, the brain needs two types of cells, neurons and astrocytes, to work closely with each other. Research has shown a great deal of the changes that occur in neurons during olfactory, or smell, perception, but what are the astrocyte responses and how they contribute to the sensory experience remains unclear. Researchers at Baylor College of Medicine and collaborating institutions report in the journal Science the responses of astrocytes to olfactory stimulation, revealing ...

As the body ages, organ function progressively declines and the risk for a wide range of diseases, including cardiovascular disease, cancer and neurodegenerative diseases, increases. Understanding how the body ages is an intense area of research as it will potentially illuminate ways to promote healthy aging. Researchers at Baylor College of Medicine, Chan Zuckerberg Biohub San Francisco, Genentech, Inc. and collaborating institutions are breaking a path in that direction. They report in the journal Science, the first Aging Fly Cell Atlas (AFCA), ...

Controlling chemical reactions to generate new products is one of the biggest challenges in chemistry. Developments in this area impact industry, for example, by reducing the waste generated in the manufacture of construction materials or by improving the production of catalysts to accelerate chemical reactions. For this reason, in the field of polariton chemistry - which uses tools of chemistry and quantum optics - in the last ten years different laboratories around the world have developed experiments in optical cavities to manipulate the chemical reactivity of molecules at room temperature, ...

Tzu-Chiao Lu, Maria Brbic and colleagues have completed the Aging Fly Cell Atlas, a single-nucleus transcriptome map of the Drosophila melanogaster fly as it ages. Aging is known to be a risk factor for many diseases across many animals including humans, but understanding how the process affects cell composition and different cell types is still mostly unknown, making the new atlas a valuable reference in further studies. Lu et al. used single-nucleus RNA sequencing to generate the Fly Cell Atlas that profiles ...

New high-precision argon isotope dating of the Ontong Java Plateau indicates that it is 10 million years younger than previously thought, according to Peter Davidson and colleagues. The Ontong Java Plateau is part of a massive underwater volcanic eruption – possibly the largest in Earth’s history – that took place in the Cretaceous Period in the equatorial western Pacific Ocean. This huge igneous emplacement has been proposed as the cause of Ocean Anoxic Event (OAE) 1a – a short period of severely reduced oxygen in the ocean - but the new dates for the eruption suggest it happened after OAE 1a. Some researchers ...

The so-called three-way catalytic converter in the exhaust system of a car consists of expensive materials and only works correctly when the exhaust gases have a temperature that is several hundred degrees Celsius. As a result, when you start your car, or when you drive a hybrid car in which the petrol engine and electric motor alternate between driving the powertrain, the gases leaving the exhaust still contain toxic carbon monoxide. In a new Science article, scientists led by Emiel Hensen now show that by modifying the carrier material of the catalyst, it is possible to almost completely convert toxic carbon monoxide into carbon dioxide gas even at room temperature. Noble ...

Numerous visual illusions are caused by limits in the way our eyes and visual neurones work – rather than more complex psychological processes, new research shows. Researchers examined illusions in which an object’s surroundings affect the way we see its colour or pattern. Scientists and philosophers have long debated whether these illusions are caused by neural processing in the eye and low-level visual centres in the brain, or involve higher-level mental processes such as context and prior knowledge. In the new study Dr Jolyon Troscianko, from the University of Exeter, co-developed a model that suggests simple limits to neural responses – not deeper ...

The rapid advance of artificial intelligence has generated a lot of buzz, with some predicting it will lead to an idyllic utopia and others warning it will bring the end of humanity. But speculation about where AI technology is going, while important, can also drown out important conversations about how we should be handling the AI technologies available today. One such technology is generative AI, which can create content including text, images, audio, and video. Popular generative AIs like the chatbot ...

PCOS affects 7% to 10% of women and is the most common cause of infertility. It is also linked to metabolic health problems such as diabetes, cardiovascular health conditions, and mental health conditions including depression and anxiety. “Although PCOS, depression and anxiety have a substantial correlation, ...

People with polycystic ovary syndrome (PCOS) have a 47% increased risk for death at a younger age compared with those without the condition, according to research being presented on Sunday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago, Ill. PCOS is a common cause of infertility in women, and it occurs in 7% to 10% of women of reproductive age. Women with PCOS may have higher than normal levels of testosterone and other reproductive hormones called androgens, irregular periods, and/or cysts on the ovaries. The condition raises the risk of developing diabetes and cardiovascular conditions. “The results highlight the need ...

Major fungal infections have become more common across the globe, and one unexpected phenomenon among the rise of fungi is life-threatening infections as a result of a complication of certain immunotherapies and small molecule kinase inhibitors.    A scientist at the Hackensack Meridian Center for Discovery and Innovation (CDI) has identified the specific mechanistic cause of one such phenomenon, which will likely save lives into the future, via a new publication.    The paper “C5a-licensed phagocytes drive sterilizing immunity during systemic fungal infection” appeared in the journal Cell ...

– By Dan Mullen Wildfires have become increasingly frequent due to climate change, with record occurrences in areas not historically prone to them. In California, wildfires and regional power shutoffs have cost billions and taken lives. For some 46 million Americans living next to forests – at what scientists call the “wildland-urban interface” (WUI) – the risks of wildfire can be especially acute. Microgrids can build resilience in vulnerable communities. By using small-scale, local energy sources and disconnecting from regional grids during emergencies, they can deliver essential services to keep homes and communities ...

In a paper published in Nature Photonics, the research team from the Center for Quantum Information and Communication – Ecole polytechnique de Bruxelles of Université libre de Bruxelles, has found an unexpected counter-example to common knowledge on photon bunching. One of the cornerstones of quantum physics is Niels Bohr's complementarity principle, roughly speaking the fact that objects may behave either like particles or like waves. These two mutually exclusive descriptions are well illustrated in the iconic double-slit experiment, ...

Washington, DC—As the world heats up due to climate change, how much can we continue to depend on plants and soils to help alleviate some of our self-inflicted damage by removing carbon pollution from the atmosphere? New work led by Carnegie’s Wu Sun and Anna Michalak tackles this key question by deploying a bold new approach for inferring the temperature sensitivity of ecosystem respiration—which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. Their findings are published in Nature Ecology & Evolution. “Right now, plants in the terrestrial ...

Giving schools the right resources and training to teach pupils about mental health really can have a positive impact on young people’s wellbeing. New research by Welsh academics has just been published demonstrating the benefits of improving pupils’ mental health literacy and reducing the stigma around mental health issues at a crucial stage in a young person’s life. Most mental health problems start in the teenage years with a recent survey identifying that two in five young people report mental health symptoms. However, due to poor knowledge ...
