Study uses artificial system to describe how space and time data are combined in human brain A computer network closely modelled on part of the human brain is enabling new insights into the way our brains process moving images - and explains some perplexing optical illusions. By using decades worth of data from human motion perception studies, researchers have trained an artificial neural network to estimate the speed and direction of image sequences. The new system, called MotionNet, is design...

Repeated Fires Drive Long-Term Changes to Tree Communities, Reduce Their Population Written by AZoCleantechFeb 26 2021 Several decades of data related to the effect of recurrent fires on ecosystems throughout the world have been analyzed by researchers from the University of Cambridge.

Published recently in the Nature Ecology and Evolution journal, the findings of the study indicate that recurrent fires are inducing long ter...

Study Reveals New Insights for Developing Lithium Metal Batteries Written by AZoMFeb 26 2021 Nanoengineers from the University of California, San Diego (UC San Diego) have gained a new fundamental insight for designing lithium metal batteries that work well at very low temperatures; specifically, the weaker the electrolyte binds to lithium ions, the better.

Single dose of Pfizer BioNTech vaccine can reduce asymptomatic SARS-CoV-2 infections New data from Addenbrookes Hospital in Cambridge suggests that a single dose of the Pfizer BioNTech vaccine can reduce by four-fold the number of asymptomatic SARS-CoV-2 infections. This implies that the vaccine could significantly reduce the risk of transmission of the virus from people who are asymptomatic, as well as protecting others from getting ill. The study by a team at Cambridge University Hospitals NH...

A team of engineers has identified the 'violent' physical processes at work inside the lungs which cause wheezing, a condition which affects up to a quarter of the world's population.

An LSU Health New Orleans School of Public Health study reports a positive association between social vulnerability and COVID-19 incidence at the census tract level and recommends that more resources be allocated to socially vulnerable populations to reduce the incidence of COVID-19.

Study Describes Key Stage in the Beginning of Great Glaciations Written by AZoCleantechFeb 22 2021 A key stage at the start of the great glaciations has been described for the first time by a new study in which the Andalusian Earth Sciences Institute (IACT) (CSIC-UGR) was involved. The study suggests that it can occur again to Earth in the future. Sampling an iceberg during the Powell 2020 research expedition close to the “Juan Carlos I” Spanish Antarctic Base/José Abel Flores.

Levels of IgG antibodies may influence COVID-19 outcomes COVID-19, the source of the current pandemic, may be caused by a single virus, but it has a variety of presentations that make treatment difficult. Children, for example, almost exclusively experience mild or asymptomatic COVID-19, while adults can develop severe or even fatal COVID-19. But children who contract COVID-19 are at risk for a rare but serious syndrome called multisystem inflammatory syndrome in children (MIS-C). Severe cases ...

New study sheds light on potential pathophysiological mechanism underlying delirium Delirium, a common syndrome among older adults, particularly in those who have recently undergone surgery, critically ill patients in the ICU, and in older patients with multiple health issues, is a form of acute confusion that is characterized by poor attention, disorientation, impaired memory, delusions, and abrupt changes in mood and behavior. Moreover, patients who experience delirium are at increased risk o...

Physical comorbidity is associated with high psychological distress Among patients with cancer, having additional physical comorbidities was linked with a higher risk of experiencing psychological distress. The finding comes from a Psycho-Oncology analysis of 2017 data from the National Health Survey of Spain. The analysis included 484 patients who reported a cancer diagnosis and 484 matched controls without a history of cancer. Compared with controls, patients with cancer reported more physic...
