How COVID-19 kills

A new study explains the mechanisms of COVID-19, revealing how the virus triggers an immune system overreaction, resulting in a cytokine storm. This can lead to respiratory failure, as well as damage to organs such as the heart and kidneys. Treatment focuses on managing symptoms and supporting organ function.

Gut ecology

A team of UC Santa Barbara researchers proposes a technique called SPARC to manipulate certain parameters in a mathematical gut microbiome model toward a target composition. This approach offers a systematic understanding of how environmental factors and species interactions can be controlled to achieve a stable gut microbiome.

Pitt researchers create durable, washable textile coating that can repel viruses

A team of researchers from the University of Pittsburgh has developed a novel textile coating that can repel viruses and bacteria, making it potential candidate for creating safely reusable personal protective equipment (PPE). The coating was tested against adenovirus types 4 and 7 and shown to be effective in repelling these viruses.

EULAR 2020

The EULAR 2020 study investigates the connection between breast cancer, anti-hormonal therapy, and rheumatoid arthritis. The results show that the risk of breast cancer in women with RA is lower than in women with healthy joints, and no association was found between anti-hormonal breast cancer prophylaxis and later RA.

FSU researchers find even small disturbances can trigger catastrophic storms

Researchers at Florida State University have found that even minor changes in atmospheric conditions can lead to the development of hurricanes. The study used numerical models to simulate cloud formation and found that most simulations produced major hurricanes in a range of latitudes, including areas near the equator.

Early detection of Alzheimer's disease with dynamic MRI measurement of glucose in brain

A new study developed a non-invasive molecular imaging approach using dynamic MRI to measure glucose level changes in the brain lymphatic system. This method helps identify Alzheimer's disease at early stages, allowing treatments to start promptly. The technique uses glucose as a 'tracer' and is compatible with existing MRI machines, m...

Is video game addiction real?

A recent six-year study on video game addiction found that about 90% of gamers do not play in a way that is harmful or causes negative long-term consequences. However, a significant minority can become truly addicted to video games, suffering mentally and socially. The study identified predictors such as being male and having low level...

T. rex's long legs were made for marathon walking

A new study by University of Maryland researchers suggests that long legs evolved among the biggest dinosaurs to help them conserve energy and go the distance while searching for prey. The study found that larger dinosaur species with longer legs needed less energy to move, giving them an advantage in terms of efficiency.

New insights into links between national income and obesity

Analysis of data from 147 countries found a strong association between rising incomes and increasing obesity rates, with an average increase in obesity rates for every 1% rise in GDP per capita. The study suggests that policy initiatives may be necessary to combat obesity in low- and middle-income countries undergoing income growth.

NMR confirms molecular switches retain function in 2D-array

Researchers from IOCB Prague synthesized regular 2D assemblies of isotopically labelled molecular switches, measuring their isomerization properties. The team found that formation of the assembly does not compromise the photochemical switching properties of the embedded molecules.

COVID-19 news from Annals of Internal Medicine

The American College of Physicians has issued new Practice Points stating that hydroxychloroquine and azithromycin do not support COVID-19 prophylaxis or treatment. However, they may be used in clinical trials with informed decision-making. Additionally, research suggests that RT-PCR tests for SARS-CoV-2 have low sensitivity, particula...
