A University of Queensland study has found no link between exposure to water fluoridation as a young child and negative cognitive development. Professor Loc Do from UQ's School of Dentistry said the IQ scores of 357 people who had participated in the 2012-2014 National Child Oral Health Study were assessed by registered psychologists to see if their exposure to fluoride as a young child impacted their brain development.

A team of international scientists has unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-Moon system and the broader solar system. The pioneering study explores the isotopic signatures of lunar water, revealing a mix of indigenous and cometary sources.

Researchers find patterns in anaphylaxis symptoms that could help people manage their health risks Findings of a new study into severe allergic reactions offer a sobering warning to people allergic to tree nuts and, more broadly, could lead to quicker diagnoses in emergency care for people with all'anaphylactic allergies.

Bonn researchers show how disease-relevant genes can be identified more easily The identification of genes involved in diseases is one of the major challenges of biomedical research. Researchers at the University of Bonn and the University Hospital Bonn (UKB) have developed a method that makes their identification much easier and faster: they light up genome sequences in the cell nucleus.

MIT engineers developed AI frameworks to identify evidence-driven hypotheses that could advance biologically inspired materials. Crafting a unique and promising research hypothesis is a fundamental skill for any scientist. It can also be time consuming: New PhD candidates might spend the first year of their program trying to decide exactly what to explore in their experiments.

A binary star system at the center of the Milky Way provides new clues as to how stars form around the central black hole An international research team led by Florian Peißker has for the first time found a binary star in the immediate vicinity of the supermassive black hole Sagittarus A* at the center of our galaxy.

Artificial intelligence (AI) systems tend to take on human biases and amplify them, causing people who use that AI to become more biased themselves, finds a new study by UCL researchers. Human and AI biases can consequently create a feedback loop, with small initial biases increasing the risk of human error, according to the findings published in Nature Human Behaviour .

VU Amsterdam closes during the holidays. Please ask your questions on time and arrange your affairs before 21 December. Questions, requests and notifications will be taken up again from 6 January. Researchers from VU Amsterdam and Amsterdam UMC have published new findings on the impact of muscle changes on post-COVID patients.

Research could help improve motor rehabilitation programs and assistive robot control. Researchers have developed a model that explains how humans adapt continuously during complex tasks, like walking, while remaining stable.

Mothers living within 20 kilometres of waste incinerators may have a small increase in the total levels of two chemical pollutants in their body. In an analysis led by researchers at Imperial College London, scientists have shown an association between women's exposure to emissions from municipal waste incinerators (MWIs) and small increased levels of polychlorinated biphenyls (PCBs) and dioxins found in their milk.

This year, Lawrence Berkeley National Laboratory (Berkeley Lab) led research that pushes the boundaries of science and technology. From advancing our understanding of the universe to innovations in microelectronics, artificial intelligence, quantum science, and biomanufacturing, the lab's teams have achieved remarkable milestones across diverse fields.

A MedUni Vienna study has identified a new approach to the drug treatment of metabolic liver diseases. In an experimental study, pharmacological inhibition of an enzyme that plays a central role in fat metabolism promoted liver health reduced liver fat, inflammation and fibrotic remodeling (connective tissue scarring).

Innosuisse, the Swiss innovation promotion agency, supports research-based innovation to strengthen the international competitiveness of Swiss industry. In projects, companies work together with universities or research institutes such as Empa to bring innovative ideas to the market. Empa is currently involved in around 80 such projects.

Neural implants contain integrated circuits (ICs) - commonly called chips - built on silicon. These implants need to be small and flexible to mimic circumstances inside the human body. However, the environment within the body is corrosive, which raises concerns about the durability of implantable silicon ICs.

The Moon is much older than previously thought. Its crust was reheated after its formation - and has thus misled researchers in determining its age After its formation, the Moon may have been the scene of such immense volcanic activity that its entire crust melted several times and was completely churned through.

Scientists at EPFL have developed "lymphomoids," a pioneering cancer model that preserves the structure and multicellular composition of lymphoma tumors in the lab. Lymphomoids offer an innovative way to test the efficacy of lymphoma treatments and better predict individual responses. Cancer is notoriously complex, with each tumor responding to different therapies.

Study identifies emotional benefits of both giving and receiving personalised gifts. There is joy in giving but research from the University of Bath shows that personalisation can transform a gift from a mere object into a more meaningful experience that raises recipients' self-esteem and makes them feel more cherished.

Caltech's John O'Doherty is on a quest to understand how human brains make decisions: how they gather evidence about their environments and their own impacts on these environments and then apply this information to their decision-making. Researchers in his lab examine subjects to find how brains learn from positive and negative feedback, and why some brains learn more easily and effectively than others.

Bioengineers at Caltech have developed a new imaging technology that could offer surgeons a fast and cost-effective way to image tissue samples in the operating room to determine whether the entirety of a tumor has been removed or if additional cuts are needed. The researchers describe the new technique, which they call parallel ultraviolet photoacoustic microscopy (PUV-PAM), in a paper in the December 11 issue of the journal Science Advances .

Caltech researchers have developed a new method to map the positions of hundreds of DNA-associated proteins within cell nuclei all'at the same time. The method, called ChIP-DIP (Chromatin ImmunoPrecipitation Done In Parallel), is a versatile tool for understanding the inner workings of the nucleus during different contexts, such as disease or development.
