Additional data can help differentiate subtle gestures, hand positions, facial expressions The Complexity of Sign Languages Sign languages have been developed by nations around the world to fit the local communication style, and each language consists of thousands of signs. This has made sign languages difficult to learn and understand. Using artificial intelligence to automatically translate the signs into words, known as word-level sign language recognition, has now gained a boost in accuracy through the work of an Osaka Metropolitan…
The regions of the Arctic are particularly vulnerable to climate change. However, there is a lack of comprehensive scientific information about the environmental changes there. Researchers from the Helmholtz Center Hereon have now examined inorganic carbon components, nutrients and trace elements in fjord systems. The result: the melting glacier ice is changing the chemical composition of the water in the fjords, causing ecosystems to become unbalanced. The study was recently published in the journal “Global Biogeochemical Cycles”. Impact of Freshwater…
New genetic risk factors for depression have been identified across all major global populations for the first time, allowing scientists to predict risk of depression regardless of ethnicity. The world’s largest and most diverse genetic study ever into major depression has revealed nearly 300 previously unknown genetic links to the condition, experts say. 100 of the newly discovered genetic variations – small differences in the DNA sequence that makes up a gene – were identified due to the inclusion of…
Low back pain is a leading cause of disability worldwide with many treatments, such as medication, often failing to provide lasting relief. Researchers from the University of Sydney’s Centre for Rural Health have uncovered a possible solution. Their study, published in JAMA Network Open, found integrating lifestyle support into back pain care could reduce disability and enhance quality of life. Study Evaluates Lifestyle-Based Outcomes The randomised controlled trial included 346 participants from across Australia, all of whom had chronic low back pain and…
A research team from the Medical Faculty of the University of Duisburg-Essen and the University Hospital Essen has developed a new cell culture model that can be used to better investigate the interaction between tumor cells and the tumor environment in retinoblastoma. Retinoblastoma is a rare eye cancer that primarily affects children. With the new model, the researchers hope to advance new eye-preserving therapies and sustainably improve treatment options for children with retinoblastoma. The new cell model was recently presented…
Groundwater and multilevel cooperation in recovery efforts mitigated water crisis after flooding. Converting Disasters into Opportunities Society is often vulnerable to disasters, but how humans manage during and after can turn devastation into opportunities for improved resilience. An Alternative Water Source: Private Wells For instance, private wells are attracting attention as an alternative resource for securing water for daily use and consumption in the event the water supply is cut off after a disaster. However, there are few records on…
Scientists at the University of Stuttgart have succeeded in controlling the structure and function of biological membranes with the help of “DNA origami”. The system they developed may facilitate the transportation of large therapeutic loads into cells. This opens up a new way for the targeted administration of medication and other therapeutic interventions. Thus, a very valuable instrument can be added to the toolbox of synthetic biology. Prof. Laura Na Liu and her team published their findings in the journal…
A new paper in Nicotine & Tobacco Research, published by Oxford University Press, finds that smoking has a negative effect on earnings among younger workers. This is particularly true among the less well educated. Smoking Kills. But How? The adverse health effects of smoking are well known. Smoking increases the risk of various cancers, respiratory issues, and cardiovascular diseases, with approximately 14% of all deaths in 2019 attributed to smoking. Despite smoking rates declining since the 1990s, in 2019 18% of…
Importance of RNA modifications for the development of resistance in fungi raises hope for more effective treatment of fungal infections. An often-overlooked mechanism of gene regulation may be involved in the failure of antifungal drugs in the clinic. This has been discovered by a German-Austrian research team led by the Leibniz Institute for Natural Product Research and Infection Biology – Hans Knöll Institute (Leibniz-HKI). The study focused on the mold fungus 𝘈𝘴𝘱𝘦𝘳𝘨𝘪𝘭𝘭𝘶𝘴 𝘧𝘶𝘮𝘪𝘨𝘢𝘵𝘶𝘴, which can cause life-threatening infections, especially in…
An international team of researchers, including scientists from the HSE Centre for Language and Brain, has identified the causes of impairments in expressing grammatical tense in people with aphasia. They discovered that individuals with speech disorders struggle with both forming the concept of time and selecting the correct verb tense. However, which of these processes proves more challenging depends on the speaker’s language. The findings have been published in the journal Aphasiology. What is Aphasia? Aphasia is a severe speech disorder, often…
From the persistent droughts of southern Africa and Central America in the early part of the year to the more recent devastating extreme rainfall in Spain and the deadly Hurricane Helene along America’s east coast, 2024 has been a year of climate events that affected the lives of billions of people. A “Climate-Resilient” Future In a recent paper published in Advances in Atmospheric Sciences, an international team of scientists led by Dr Wenxia Zhang at the Institute of Atmospheric Physics, Chinese…
Researchers at the Max Planck Institute for Chemical Physics of Solids, in collaboration with Chongqing University and the Max Planck Institute of Microstructure Physics, have achieved a breakthrough in topological thermoelectrics. In their study, published in “Nature Materials”, they demonstrate a groundbreaking development in thermoelectrics: By applying a weak magnetic field, the cooling performance of topological materials at low temperatures can be significantly improved. It marks a significant advance in magneto-thermoelectrics, which can be a cost-effective and energy-efficient alternative to…
The closest relatives of humans adapt genetically to habitats and infections Survival of the Fittest: Genetic Adaptations Uncovered in Chimpanzees Görlitz, 10.01.2025. Chimpanzees have genetic adaptations that help them survive in different forest and savannah habitats. This is the result of a study published today in the renowned journal “Science”. An international research team led by University College London (UCL) shows that some of these adaptations could also protect the animals from malaria. The researchers emphasize that their results provide…
The Fiber Gap: A Growing Concern in American Diets Fiber is well known to be an important part of a healthy diet, yet less than 10% of Americans eat the minimum recommended amount. A new study from Stanford Medicine might finally convince us to fill our plates with beans, nuts, cruciferous veggies, avocados and other fiber-rich foods. The research, which will be published in Nature Metabolism on Jan. 9 identified the direct epigenetic effects of two common byproducts of fiber digestion and found that…
HIRI researchers uncover control mechanisms of polysaccharide utilization in Bacteroides thetaiotaomicron. Researchers at the Helmholtz Institute for RNA-based Infection Research (HIRI) and the Julius-Maximilians-Universität (JMU) in Würzburg have identified a protein and a group of small ribonucleic acids (sRNAs) in Bacteroides thetaiotaomicron, which regulate sugar metabolism. These discoveries shed light on how this gut microbe adapts to varying nutritional conditions. The findings deepen our understanding of this bacterium’s role in the human gut and may pave the way for new…
Scientists show how a mutated gene harms red and white blood cells. LA JOLLA, CA—Scientists at La Jolla Institute for Immunology (LJI) have discovered how a mutated gene kicks off a dangerous chain of events during blood cell production. The study, published recently in the Proceedings of the National Academy of Sciences, reveals how a mutated gene called ASXL1 is involved in a disease called clonal hematopoiesis, a precursor to malignant diseases such as myeloid malignancies and chronic monomyelocytic leukemia. “We know that…
