No signs of brain injury post-acute COVID-19

A recent study from University of Gothenburg found that all participants achieved normalization of CNS injury biomarkers, regardless of previous disease severity or persistent neurological symptoms. This suggests that post-COVID-19 neurological sequelae are not due to active brain injury, contradicting previous findings.

Scientists reverse a key hallmark of motor neurone disease in the laboratory

Researchers at The Francis Crick Institute successfully reversed a key hallmark of motor neurone disease by blocking the activity of an enzyme called VCP. This breakthrough, published in Brain Communications, suggests that the abnormal accumulation of proteins involved in RNA regulation might be a factor contributing to the disease.

Lab-grown beating heart cells identify potential drug to prevent COVID-19-related heart damage

A team of scientists at the University of Cambridge has developed a lab-grown model of heart cells that mimic the behavior of real heart cells and are vulnerable to SARS-CoV-2 infection. The researchers showed that an experimental peptide drug, DX600, can prevent the virus from entering the heart cells and reduce levels of infection.

NUS researchers link neurodegenerative disease protein to defective cholesterol metabolism

Researchers from NUS have discovered that brain cells rely on the TDP-43 protein to maintain the myelin sheath, which is crucial for neuron insulation. The study suggests that restoring cholesterol levels through drug intervention could be a novel therapeutic approach for diseases associated with TDP-43.

Far out: Why political parties go to extremes

A recent study modelled social, economic, and personal factors influencing voters and parties to identify four key levers that tip the balance towards political extremes. Social contagion and macro-economic factors such as employment and economic growth play a significant role in driving polarization.

Heat-related symptoms affected one-quarter of Americans during summer of 2020

A new study found that one-quarter of Americans suffered from heat-related symptoms in 2020, with women, low-income households, and non-white populations most vulnerable. The research also revealed that the pandemic exacerbated existing vulnerabilities, making it harder for people to access cooling centers and medical care.

Herbal medicines demonstrate potency against bartonella, a disease-causing pathogen, according to new lab study

A new lab study finds that three herbal medicines - Chinese skullcap, Cryptolepis, and Japanese knotweed - have high activity against bartonella henselae and Borrelia burgdorferi, the bacteria causing Lyme disease. The findings suggest these herbs may be effective in treating tick-borne infections, including babesiosis.
