New research may explain severe virus attacks on the lungs

In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers at Karolinska Institutet in Sweden describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study, which was published in Immunity,…Continue Reading

AI research survey finds machine learning needs a culture change

The machine learning community, particularly in the fields of computer vision and language processing, has a data culture problem. That’s according to a survey of research into the community’s dataset collection and use practices published earlier this month. What’s needed is a shift away from reliance on the large, poorly curated datasets used to train…Continue Reading

New Research Supports ‘Modified Gravity’ Theory

Dark matter proponents theorize that most of the known Universe is actually made of material that doesn’t interact with light, making it invisible and undetectable, but that this material accounts for much of the gravitational pull among galaxies. A counter explanation introduced by the Israeli physicist Mordehai Milgrom in 1983, the MOdified Newtonian Dynamics (MOND)…Continue Reading

Research reveals how a fungal infection activates inflammation

Scientists at St. Jude Children’s Research Hospital have identified the mechanisms behind inflammasome activation driven by infection with the fungal pathogen Aspergillus fumigatus. Fungal infection, especially with A. fumigatus, is a leading cause of infection-associated deaths in people with compromised immune systems. The work provides clues to a potential therapeutic approach for treating infectious and…Continue Reading

Research reveals how airflow inside a car may affect COVID-19 transmission risk

A new study of airflow patterns inside a car’s passenger cabin offers some suggestions for potentially reducing the risk of COVID-19 transmission while sharing rides with others. The study, by a team of Brown University researchers, used computer models to simulate the airflow inside a compact car with various combinations of windows open or closed.…Continue Reading

New research finds UK consumers highly value EU food safety standards

The research also reveals that UK consumers highly value food production that adheres to food safety standards set by the EU as well as UK produced food. The authors of the study say their findings are particularly relevant for post-Brexit trade deals and the ongoing debates about UK food standards.“Our motivation was the need to understand…Continue Reading

AI research finds a ‘compute divide’ concentrates power and accelerates inequality in the era of deep learning

AI researchers from Virginia Tech and Western University have concluded that an unequal distribution of compute power in academia is furthering inequality in the era of deep learning. They also point to the impact on academia of people leaving prestigious universities for high-paying industry jobs. The concentration of compute power at elite universities crowds out…Continue Reading

New research traces the origins of trench fever

First observed among British Expeditionary Forces in 1915, trench fever sickened an estimated 500,000 soldiers during World War I. Since then, the disease has become synonymous with the battlefield. But now, new research from an international team of scientists has uncovered evidence challenging this long-held belief. The research, published this week in PLOS ONE, outlines…Continue Reading

New research finds sensory quality of pork boosted by probiotic supplementation in feed

The Chinese research team’s objective was to compare muscle fiber characteristics, the profiles and related gene expression of amino acids and fatty acids and the metabolic regulation of these compounds in pigs fed either a control diet, an antibiotic-containing diet, or a diet with Lactobacillus reuteri (LR1) ​supplementation.The composition of amino acids and fatty acids…Continue Reading
