A dust storm that engulfed Mars in 2018 destroyed a vortex of cold air around the planet's south pole and brought an early spring to the hemisphere. By contrast, the storm caused only minor distortions to the polar vortex in the northern hemisphere and no dramatic seasonal changes.
New European Union regulations on batteries could offer a huge boost to the global decarbonisation mission - but only if it leverages its political and economic weight to ensure a fairer global marketplace.
As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?
Researchers at the UNC Lineberger Comprehensive Cancer Center demonstrated in a clinical trial in Malawi that a five-drug combination chemotherapy provided curative benefit compared to current standard-of care-therapy in people diagnosed with lymphoma, and now they have determined this option is also cost-effective.
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,
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.
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.
Newly-hatched pterosaurs may have been able to fly but their flying abilities may have been different from adult pterosaurs, according to a new study.Researchers from the Universities of Portsmouth and Bristol, along with palaeontologist Darren Naish, found that hatchling humerus bones were stronger than those of many adult pterosaurs, indicating that they would have been strong enough for flight.
In one out of every six local authorities, rates of hunger are more than 150 per cent the national average. Shockingly, in one in 10 local authorities, the rate is almost double, according to new research by the University of Sheffield.
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.
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.
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.
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.
Titanium dioxide, promising anode materials for sodium ion batteries, nonetheless, suffers from its inferior charge transfer kinetics owing to low diffusion coefficient and electronic conductivity, which will result in unsatisfactory high-rate capability. Here, an oxygen vacancy (OV) engineering assisted in high-content anion (S/Se/P) doping strategy to enhance its charge transfer kinetics for ultrafast sodium-storage performance is proposed to address these issues and expectative results have been obtained.
An international research team has come up with an innovative method for metal recovery from industrial waste. The new method allows the simultaneous recovery of multiple metals from waste oxides in a single process. This novel route will lower the burden on waste storage facilities with significant contributions to the economic and environmental sustainability of industrial waste management. The study was published in Journal of Environmental Management.
Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team in Switzerland has now developed the first chromium complex that emits light in the coveted, longer wavelength NIR-II range. In the journal Angewandte Chemie, the team has introduced the underlying concept: a drastic change in the electronic structure of the chromium caused by the specially tailored ligands that envelop it.
A research team led by Wim Annaert (VIB-KU Leuven) uncovered the early assembly of gamma-secretase, a protein complex linked to numerous cellular processes including the development of Alzheimer's disease. In a first step, two dimeric subcomplexes are formed, which independently exit the ER and only afterwards assemble into a four-subunit complex. This 'buckle up' mechanism is thought to prevent premature assembly and activity.
A joint research team from the University of Hong Kong reported the development of a transferrable and integrative type I CRISPR-based platform that can efficiently edit the diverse clinical isolates of Pseudomonas aeruginosa, a superbug capable of infecting various tissues and organs and a major source of nosocomial infections. The technique can accelerate the identification of resistance determinants of multidrug resistant (MDR) pathogens and the development of novel anti-resistance strategies.
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 transferred to a cyclist's head in the event of an accident and lowering the chances of serious injury.
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.
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.
Scientists from Goethe University Frankfurt, University of Warsaw, State Authority for Mining, Energy and Geology in Hanover, and from other institutions have found in Salzgitter-Salder what researchers have been searching for for more than 20 years: A geological formation that perfectly represents the transition from the Cretaceous Turonian to the Coniacian Age. The former limestone quarry is now considered a global reference point (GSSP) for the turn of the ages 89.4 million years ago.
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 a Reddit dataset that was collected by DARPA.
Research led by Queen Mary University of London provides new insight into the mechanisms that lead to uncontrolled inflammation in COVID-19 patients.
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.
