Neuroscientists at the Ruhr-Universität Bochum (RUB) together with colleagues at the Freiburg University show that this is not strictly the case. Instead, they show that prediction errors can occasionally appear as visual illusion when viewing rapid image sequences. Thus, rather than being explained away prediction errors remain in fact accessible at final processing stages forming perception. Previous theories of predictive coding need therefore to be revised. The study is reported in Plos One on 4. May 2020.
The greenhouse gas methane is a crucial factor of climate change in the Arctic and globally as well. Yet, methane emissions in the far north are difficult to measure across large regions. In the past, researchers usually scaled-up selective point measurements to generate landscape-scale methane flux estimates. Now, a group of researchers from Alaska and Germany is reporting for the first time on remote sensing methods that can observe thousands of lakes and thus allow more precise estimates of methane emissions.
Highly complex organisms can arise from a single cell, which is one of the true miracles of nature. Substances known as morphogens have an important role in this development, namely by signalling to cells where they should go and what they should do. These signal molecules guide biological processes such as the formation of body axes or the wiring of the brain. To investigate such processes in more detail, researchers have to be able to position the signal molecules among living cells in three-dimensional space.
The genetic information within our cells is what makes humans unique. The cell nucleus has a complex structure that harbors this genetic information. The main component of the nucleus is chromatin, an intercalated pool of genes and proteins. Promyelocytic leukemia (PML) bodies are structures found closely associated with chromatin, suggesting that they may be involved with genetic function. However, the exact nature of the relationship between PML bodies and genes is unknown.
The presence and variety of mobile devices in Spanish households, regardless of social and economic circumstances, has been mainstream for years. Several studies focus on parental mediation in children's consumption of smart screens, although there is a lack of scientific evidence concerning how the level of training and the professional profile of mothers and fathers affect children's digital media consumption.
By disrupting the expression of a particular gene and observing how this change affects expression of other genes, researchers can learn about the cellular roles of the disrupted gene. New technologies such as Perturb-seq offer unprecedented detail and depth of insight from such genetic disruption studies, but technical and practical hurdles have limited use of Perturb-seq.
WASHINGTON -- David Storm, a research physicist, and Tyler Growden, an electrical engineer, both with the U.S. Naval Research Laboratory, developed a new gallium nitride-based electrical component called a resonant tunneling diode (RTD) with performance beyond the anticipated speed of 5G.
The fifth-generation network technology is now just starting to roll out across the United States.
Storm and Growden's electronic component diode research findings were published March 19, 2020 in the academic journal Applied Physics Letters.
Hospital staff may be carrying SARS-CoV-2, the coronavirus that causes COVID-19 disease, without realising they are infected, according to a study by researchers at the University of Cambridge.
Researchers from Trinity College Dublin are calling on the government in Ireland to change recommendations for vitamin D supplements [Monday 11th May 2020].
A new publication from Dr Eamon Laird and Professor Rose Anne Kenny, School of Medicine, and the Irish Longitudinal Study on Ageing (TILDA), in collaboration with Professor Jon Rhodes at University of Liverpool, highlights the association between vitamin D levels and mortality from COVID-19.
Amsterdam, May 12, 2020 - The worldwide COVID-19 pandemic has infected more than 4 million people and killed close to 280,000.1 Finding a vaccine has become a global public health priority. However, creating a viable vaccine might take a long time; scientists estimate a vaccine may be available in between 12 and 18 months.
The question of whether democracies behave differently from non-democracies is a central, and intense, debate in the field of international relations. Two intellectual traditions - liberalism and realism - dominate. Liberals argue that democracies do indeed behave differently, while realists insist that regime type and ideology are of little relevance in understanding foreign policy behavior.
May 11, 2020, Alexandria, Va., USA--The Journal of Dental Research published today the results of a study that demonstrated that community water fluoridation is not associated with increased risk of osteosarcoma.
WOODS HOLE, Mass. -- Nearly a quarter of Americans suffer from arthritis, most commonly due to the wear and tear of the cartilage that protects the joints. As we age, or get injured, we have no way to grow new cartilage. Unlike humans and other mammals, the skeletons of sharks, skates, and rays are made entirely of cartilage and they continue to grow that cartilage throughout adulthood.
Early life experiences of zebra finches have a big effect on the construction of their first homes, according to a new study by researchers at the University of Alberta's Faculty of Science and the University of St Andrews' School of Biology.
The study shows that the presence of an adult bird as well as the types of materials available in early adolescence influence two key aspects of first-time nest building: material preference and construction speed.
New psychology research from the University of Konstanz reveals that stress changes the way we deal with risky information - results that shed light on how stressful events, such as a global crisis, can influence how information and misinformation about health risks spreads in social networks.
