Researchers at the Inselspital, Bern University Hospital and the University of Bern have developed an AI-based tool that detects and classifies abnormalities of the coronary arteries in CT images with high precision. This could significantly improve the diagnosis and treatment of rare heart diseases.

Differences in the distribution of certain proteins and markers in the brain may explain why some people first experience vision changes instead of memory loss in Alzheimer's disease, finds a new study by UCL researchers. Posterior cortical atrophy (PCA) is a rare form of Alzheimer's disease that, rather than causing problems with memory, leads to difficulties with reading, navigating, and recognising objects.

Special anatomical structures in the throat greatly enrich the vocal repertoire of New World monkeys A recent investigation led by voice scientist Christian T. Herbst from the University of Vienna and colleagues from Anglia Ruskin University provides new insights into the vocal capabilities of New World monkeys, the group of all'original primates of the American continent: They can produce "voice breaks" similar to human yodeling, but support a much wider range of frequencies.

Bonobos - our closest living relatives - create complex and meaningful combinations of calls resembling the word combinations of humans. This study, conducted by researchers at the University of Zurich and Harvard University, challenges long-held assumptions about what makes human communication unique and suggests that key aspects of language are evolutionary ancient.

While medical centres use ultrasound daily, so far this technology is not capable of observing body tissues at the scale of cells. Physicists from TU Delft have developed a microscopy technique based on ultrasound to reveal capillaries and cells across living organs-something that wasn't possible before.

A study examines the relationship between gender roles and the desire to have children in Scandinavia To the point Low Birth Rates: Researchers examined the link between gender roles and the desire to have children in Denmark, Finland, and Norway. Structural barriers are only a factor: In highly gender-equal societies, declining birth rates cannot automatically be attributed to everyday structural challenges faced by parents.

Organoids have revolutionized science and medicine, providing platforms for disease modeling, drug testing, and understanding developmental processes. While not exact replicas of human organs, they offer significant insights. The Siegert group at the Institute of Science and Technology Austria (ISTA) presents a new organoid model that reveals details of the developing nervous system's response to viral infections, such as Rubella.

To predict toxic algal blooms, researchers from Eawag recommend a combination of species identification and chemical measurements. Now, a new study confirms that there is no magic formula and that, instead, specific indicator molecules are needed for each lake. Cyanobacteria, also known as blue-green algae, can proliferate very rapidly in lakes in the warmer months of the year.

Estimates of carbon dioxide (CO2) emissions from volcanoes may have been significantly underestimated, according to new research by The University of Manchester. Published in the journal, Science Advances , s cientists have developed an advanced sensor that can detect volcanic gases with rapid speed and precision.

Max Planck researcher Isabel Thielmann finds that dishonest behavior is consistent In brief New study shows: People who have lied once are likely to lie again in similar situations. It used to be assumed that lying is primarily situation-dependent. There is a connection between dishonest behavior and certain personality traits.

Developing new drugs to treat illnesses has typically been a slow and expensive process. However, a team of researchers at the University of Waterloo uses machine learning to speed up the development time. The Waterloo research team has created "Imagand," a generative artificial intelligence model that assesses existing information about potential drugs and then suggests their potential properties.

This novel antibiotic activates an existing "suicide" mechanism in gonococci The increase of microbes resistant to antibiotics is a growing problem. These include, for example, Neisseria gonorrhoeae , a bacterium which causes gonorrhea. Researchers from the universities in Konstanz and Vienna discover a new class of antibiotic that selectively targets Neisseria gonorrhoeae.

Phosphorylation serves as a key on-and-off switch in cell signaling, such as in the Akt pathway, which regulates cell growth and is often upregulated in cancer. Master students Tarik Husremovic and Vanessa Meier from the Leonard lab at the Max Perutz Labs now reveal, in a study published in Proceedings of the National Academy of Sciences (PNAS), that the phosphatases PHLPP1 and PHLPP2 - previously believed to dephosphorylate Akt and suppress tumor growth - are neither phosphatases nor tumor suppressors.

An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models. For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe.

A new study by McGill researchers yields insights into how the disruption of calcium transport in the brain is linked to autism and intellectual disability. The findings, published in the journal Nature, not only upend a long-held belief among neuroscientists, but could pave the way for treatments. The researchers discovered that tiny protein structures on brain cells, known as AMPA receptors, can transport calcium.

A new study reveals a long-isolated North African human lineage in the Central Sahara during the African humid period more than 7,000 years ago To the point DNA analysis from two naturally mummified individuals from Libya: More than 7,000 years ago, during the so-called African Humid Period (Green Sahara), a long isolated human lineage existed in North Africa.

Alcohol in their food increases the production of sex pheromones in male fruit flies, making them more attractive to females A team of researchers at the Max Planck Institute for Chemical Ecology has investigated why the fruit fly Drosophila melanogaster drinks alcohol and has shown that alcohol has a direct and positive effect on the mating success of male flies.

Previous studies show exposure to Tetrahydrocannabinol (THC) - the main psychoactive component in cannabis - while in utero can lead to lower birth weight and potential heart complications in newborn animal offspring. For the first time, researchers from Western's Schulich School of Medicine & Dentistry have found a potential way to prevent those effects.

Scientists have taken an important step toward the development of a potential new treatment for treating Shiga toxin-producing E. coli (STEC), the notorious bug associated with severe food poisoning. The findings - led by the University of Glasgow and published in Antimicrobials and Resistance - demonstrate, for the first time, the use of an antivirulence drug called Aurodox, a potential alternative to traditional antibiotic treatment, to be an effective treatment when used in mice models of STEC.

It shows neuroprotective and anti-inflammatory effects in animal models of the disease. Alzheimer's disease, the most common cause of dementia, is currently incurable. The current drugs available have very limited efficacy and only in mild stages of the disease. A team from the University of Barcelona has developed a promising therapeutic candidate to treat this disease, which affects more than 800,000 people in Spain.
