With its more than 40 million articles in 301 different languages, Wikipedia is one of the largest human collaboration efforts in history. One of the main pillars on which this wish to bring together the sum of all knowledge is based is the achievement of a neutral space. However, several studies suggest that the site suffers from a persistent gender bias as regards both content and the composition of its community.
Singapore, 19 April, 2021 - Researchers at the Future Urban Mobility (FM) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, have created a synthetic framework known as theory-based residual neural network (TB-ResNet), which combines discrete choice models (DCMs) and deep neural networks (DNNs), also known as deep learning, to improve individual decision-making analysis used in travel behaviour research.
A team of researchers from the Hebrew University of Jerusalem has proven the linkages between ultra-processed foods and reduced bone quality, unveiling the damage of these foods particularly for younger children in their developing years. The study, led by Professor Efrat Monsonego-Ornan and Dr. Janna Zaretsky from the Department of Biochemistry, Food Science and Nutrition at the University's Faculty of Agriculture, was published in the journal Bone Research and serves as the first comprehensive study of the effect of widely-available food products on skeleton development.
It has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry of the virus into host cells and represents the central point of attack for antibodies. These SARS-CoV-2 variants from mink were transmitted back to humans, raising concerns that minks could be a continuing source of infection of humans with SARS-CoV-2 variants with altered biological properties.
Stroke risk for patients with traumatic brain injuries is at its highest in the four months following injury and remains significant for up to five years post-injury, finds a new systematic review led by a team at the University of Birmingham.
There are many variants of "goblet cells" in the intestines and they seem to have different functions, according to a new study from the University of Gothenburg. The study indicates that defects in goblet cells of a particular type may be a factor contributing to ulcerative colitis, an inflammatory bowel disease.
The prevalence of intellectual disabilities, which means difficulties with learning and understanding new things, is roughly 1-2% in the population. People with a severe intellectual disability need help from others in daily activities throughout their lives.
Such disabilities can be caused by genetic changes or external factors. According to estimates, roughly 2,500 genes underlie intellectual disability, of which approximately half remain unidentified.
Language is one of the most remarkable abilities humans have. It allows us to express complex meanings and transmit knowledge from generation to generation. An important question in human biology is how this ability evolved, and researchers from the universities of Barcelona, Cologne and Tokyo have tackled this issue in a recent article, published in the journal Trends in Cognitive Sciences.
Researchers used platinum and aluminum compounds to create a catalyst which enables certain chemical reactions to occur more efficiently than ever before. The catalyst could significantly reduce energy usage in various industrial and pharmaceutical processes. It also allows for a wider range of sustainable sources to feed the processes, which could reduce the demand for fossil fuels required by them.
While studying strontium titanate with electron paramagnetic resonance, a team from KFU's Center for Quantum Technology has found that the shape of a specimen of strontium titanate influences its internal symmetry. The research was co-conducted by the Ioffe Institute of Physics and Technology (Russia) and the Institute of Physics of the Czech Academy of Sciences.
A recent study finds that social inequality persists, regardless of educational achievement - particularly for men.
"Education is not the equalizer that many people think it is," says Anna Manzoni, author of the study and an associate professor of sociology at North Carolina State University.
The study aimed to determine the extent to which a parent's social status gives an advantage to their children. The research used the educational achievements of parents as a proxy for social status, and looked at the earnings of adult children as a proxy for professional success.
ADELPHI, Md. -- Spoken dialogue is the most natural way for people to interact with complex autonomous agents such as robots. Future Army operational environments will require technology that allows artificial intelligent agents to understand and carry out commands and interact with them as teammates.
New, detailed study of the Renland Ice Cap offers the possibility of modelling other smaller ice caps and glaciers with significantly greater accuracy than hitherto. The study combined airborne radar data to determine the thickness of the ice cap with on-site measurements of the thickness of the ice cap and satellite data. Researchers from the Niels Bohr Institute - University of Copenhagen gathered the data from the ice cap in 2015, and this work has now come to fruition in the form of more exact predictions of local climate conditions.
A new study led by researchers at Johns Hopkins and the University of Pennsylvania uses computer modeling to suggest that eviction bans authorized during the COVID-19 pandemic reduced the infection rate and not only protected those who would have lost their housing but also entire communities from the spread of infections.
A joint research carried out by MIPT scientists and Harvard researchers have presented retinal cells that can integrate into the retina. This is the first successful attempt to transplant ganglion cells (retinal neurons that are destroyed by glaucoma) derived from stem cells in a lab setting. Scientists tested the technology in mice and established that the cells successfully integrated and survived for a year. In the future, the researchers plan to create specialized cell banks, which will permit individual, tailored therapy for each patient.
