As cities worldwide expand their networks of cycling paths and more cyclists take to the streets, the chances of cycling accidents and potential collisions increase as well, underscoring the need for proper cycling safety in dense urban areas. According to a World Health Organisation report in 2020, more than 60 per cent of the reported bicycle-related deaths and long-term disabilities are a result of accidents with head injuries. Researchers from Nanyang Technological University, Singapore (NTU Singapore), in collaboration with French specialty materials leader Arkema, have developed a tougher, safer bicycle helmet using a combination of materials. The new helmet prototype has higher energy absorption, reducing the amount of energy ...

With the application of a novel three-dimensional imaging technology, researchers at Karolinska Institutet in Sweden have discovered that one portion of the autonomic nervous system in the liver undergoes severe degeneration in non-alcoholic fatty liver disease. The study, which is conducted in mice and human liver tissue, shows that the degeneration of nerves is correlated with the severity of liver pathology. The results are being published in the journal Science Advances. Non-alcoholic fatty liver disease is the most common hepatic disorder, with prevalence around 25 percent globally. Approximately ...

The building sector in the U.S. accounts for 39 percent of energy use, with commercial buildings responsible for about half of that. As cities grapple with climate change, making commercial buildings more efficient is a key part of the solution. Researchers at the University of Pittsburgh Swanson School of Engineering and the Mascaro Center for Sustainable Innovation used the City of Pittsburgh to create a model built upon the design, materials and purpose of commercial buildings to estimate their energy usage and emissions. While other models may ...

FRANKFURT/HANNOVER. The international team of geoscientists led by Prof. Silke Voigt from the Goethe University Frankfurt, Prof. Ireneusz Walaszczyk from the University of Warsaw and Dr André Bornemann from LBEG have thoroughly investigated 40 metres of the geological strata sequence in the former limestone quarry at Hasselberg. The researchers determined that this is only sequence in the transition between Turonian and Coniacian without gaps and it therefore represents a perfect rock sequence to serve geoscientists from all over the world as a reference for their research - a "Global Stratotype Section and Point (GSSP)" or, in the jargon of geosciences, a "golden nail". Certain group of bivalve mollusks of the family Inoceramidae, first appeared in the Coniacian, and ...

ORLANDO, July 22, 2021 - Disagreement seems to spread online posts faster and further than agreement, according to a new study from the University of Central Florida. The finding comes from an examination of posts labeled controversial on social news aggregation site Reddit. To perform the study, the researchers analyzed more than 47,000 posts about cybersecurity in a Reddit dataset that was collected by the Computational Simulation of Online Social Behavior (SocialSim) program of the U.S. Defense Advanced Research Projects Agency. Researchers found that these posts were seen by nearly twice the number of people and traveled nearly twice as fast when compared ...

In a new study, published recently in the journal Circulation Research, scientists discover how the production of protective molecules known as specialised pro-resolving mediators (SPM) is altered in patients with COVID-19. The results suggest that treatments which increase SPM production, such as dexamethasone or SPM based drugs, could play a key role in limiting inflammation in these patients. Currently there is little understanding around the mechanisms that lead to uncontrolled inflammation in patients with COVID-19. The study found a link between decreased SPM blood levels and disrupted white blood cell responses in patients with a higher disease burden. The findings also revealed that dexamethasone, the first drug ...

More than 820 million people in the world don't have enough to eat, while climate change and increasing competition for land and water are further raising concerns about the future balance between food demand and supply. The results of a new IIASA-led study can be used to benchmark global food security projections and inform policy analysis and public debate on the future of food. Despite the fact that food supply has increased dramatically since the 1960s, the question of how to eradicate global hunger - one of the Sustainable Development Goals - and feed the growing world population in years to come, remains a major challenge. Climate change and increasing competition ...

Hematopoietic cell transplantation (HCT) is a recognized treatment option for certain blood and bone marrow cancers as well as some autoimmune and hereditary disorders. Performed to replace or modulate the body's malfunctioning hematopoietic system (which produces blood cells) or a compromised immune system following a medical condition or treatment, HCT can be autologous or allogenic. In autologous HCT, a patient's own stem cells are injected into the bloodstream, while in allogenic HCT donor stem cells are used. Although a difficult procedure, over the years, the safety of HCT has been improved ...

Irvine, Calif., July 21, 2021 -- It's not exactly X-ray vision, but it's close. In research published in the journal Optica, University of California, Irvine researchers describe a new type of camera technology that, when aimed at an object, can rapidly retrieve 3D images, displaying its chemical content down to the micrometer scale. The new tech promises to help companies inspect things like the insides of computer chips without having to pry them open -- an advancement the researchers say could accelerate the production time of such goods by more than a hundred times. "This is a paper about a way to visualize things in 3D very fast, even at video rate," said Dmitry Fishman - director of laser spectroscopy labs in the UCI Department of ...

New University of Otago research has been examining how alpine-based hedgehogs hibernate from a different perspective - their backs. Dr Nick Foster from the Department of Zoology has been involved with the Te Manahuna Aoraki project and has been attaching small transmitting 'backpacks' onto hedgehogs in the Mackenzie Basin's alpine zones. The mammals are considered pests in New Zealand for the damage they cause to native insects and wildlife throughout the country. The goal of this study, which has just been published in the New Zealand Journal of Ecology, was to find out whether hedgehogs, which can be found up to 2000 metres in summer, travel ...

FINDINGS Scientists from the UCLA Jonsson Comprehensive Cancer Center have identified a key protein, transcription factor TAF12, that plays a critical role in the formation of a preinitiation complex, which consists of over one hundred proteins that are necessary for the transcription of protein-coding genes. The team found by eliminating TAF12, the entire preinitiation complex is destroyed and the genome-wide transcription is downregulated drastically. The findings could help pave the way for cancer therapies that target TAF12, potentially stopping transcription in cancer cells and helping decrease the growth of cancerous tumors. TAF12 had previously been shown by ...

The future of Samoa's electricity system could go green, a University of Otago study has shown. Pacific Island nations are particularly susceptible to climate change and face high costs and energy security issues from imported fossil fuels. For these reasons many Pacific Island nations have developed ambitious 100 per cent renewable energy targets. However, they have not been subject to rigorous peer-reviewed studies to help develop these targets and pathways for achieving them in the same way as more developed countries. To meet this need, Otago Energy Science and Technology Masters student Tupuivao Vaiaso mapped future scenarios for Samoa's electricity system by carefully balancing renewable supply and electricity demand. The study, published in Renewable ...

Leesburg, VA, July 22, 2021--According to ARRS' American Journal of Roentgenology (AJR), the standardized non-invasive clear cell likelihood score (ccLS)--derived from MRI--correlates with the growth rate of small renal masses (cT1a, END ...

Scientists have completed the largest and most diverse genetic study of type 1 diabetes ever undertaken, identifying new drug targets to treat a condition that affects 1.3 million American adults. Several potential drugs are already in the pipeline. Drugs targeting 12 genes identified in the diabetes study have been tested or are being tested in clinical trials for autoimmune diseases. That could accelerate the drugs' repurposing for treating or preventing type 1 diabetes, the researchers say. "This work represents the largest, most ancesty-diverse study of type 1 diabetes ...

DALLAS - July 20, 2021 - UT Southwestern researchers report the first structural confirmation that endogenous - or self-made - molecules can set off innate immunity in mammals via a pair of immune cell proteins called the TLR4?MD-2 receptor complex. The work has wide-ranging implications for finding ways to treat and possibly prevent autoimmune diseases such as multiple sclerosis and antiphospholipid syndrome. The TLR4?MD-2 receptor complex is well known for its role in the body's response to infection by gram-negative bacteria. Its role in autoimmunity had been long suspected, although direct proof was lacking. The team, led by Nobel Laureate Bruce Beutler, M.D., director of the Center for the Genetics of Host Defense (CGHD), identified lipids called sulfatides ...

In one out of every six local authorities, rates of hunger are more than 150 per cent (one and a half times) the national average. Shockingly, in one in 10 local authorities, the rate is almost double, according to new research by the University of Sheffield. Researchers at the University of Sheffield Institute for Sustainable Food modelled data from the Food Foundation, who surveyed people across the UK, and for the first time were able to identify food insecurity at a local authority scale. Local authority percentages show the marked variation in levels of food insecurity between local areas and, whereas national ...

Persistence may be the key when quitting smoking using an electronic nicotine delivery system (ENDS), commonly known as vaping, a University of Otago study found. Researchers found people attempting to switch from cigarettes to ENDS reported highly varied smoking and ENDS use. They recommend people persist in their attempts to transition away from smoking, even if their progress feels slow and uncertain. Lead author Associate Professor Tamlin Conner, of the Department of Psychology, says, although people may plan to use ENDS exclusively instead of cigarettes, making the switch is not always straightforward. "We found that dual use of ENDS and cigarettes was very common, suggesting that people ...

A new quantitative study suggests people seeking asylum are more likely to experience mental health deterioration as they spend more time living in refugee camps, backing up qualitative evidence from aid organisations. The research, co-authored by Dr Francisco Urzua from the Business School (formerly Cass) alongside practitioners from Moria Medical Support (MMS) and academics from Universidad del Desarrollo, Chile and University of Amsterdam, the Netherlands measured incidences of acute mental health crises arising from extended stays in the Moria refugee camp on ...

Researchers from the School of Biomedical Engineering & Imaging Sciences at King's College London have automated brain MRI image labelling, needed to teach machine learning image recognition models, by deriving important labels from radiology reports and accurately assigning them to the corresponding MRI examinations. Now, more than 100,00 MRI examinations can be labelled in less than half an hour. Published in European Radiology, this is the first study allowing researchers to label complex MRI image datasets at scale. The researchers say it would take years to manually perform labelling of more than 100,000 MRI examinations. Deep learning typically requires tens of thousands of labelled images to ...

Scientists have developed a 'nanobody' - a small fragment of a llama antibody - that is capable of chasing out human cytomegalovirus (HCMV) as it hides away from the immune system. This then enables immune cells to seek out and destroy this potentially deadly virus. Around four out of five people in the UK are thought to be infected with HCMV, and in developing countries this can be as high as 95%. For the majority of people, the virus remains dormant, hidden away inside white blood cells, where it can remain undisturbed and undetected for decades. ...
