The cellular response that protects pigs from COVID-19

Researchers found that pig cells undergo apoptosis at a higher rate than human cells in response to SARS-CoV-2 infection, helping to limit viral replication and avoid severe illness. This discovery could lead to therapies designed to trigger apoptosis in human cells, reducing the severity of COVID-19 symptoms.

Research in mice identifies neurons that control locomotion

In a study published in Cell, researchers report that ventral spinocerebellar tract neurons (VSCTs) are both necessary and sufficient for regulating locomotor behavior in mice. Activation of VSCTs induces locomotion, while suppression halts it, demonstrating their crucial role in controlling this essential behavior.

Step Up: walking may reduce Type 2 Diabetes risk for adults 65 and older

A study published in Diabetes Care found that walking regularly at greater intensity and taking more steps can lower the risk of developing Type 2 diabetes among adults aged 65 and older. For every 1,000 additional steps per day, the risk is reduced by 6%, with a 12% reduction possible if an average adult takes 2,000 more steps daily.

THE LANCET: Initiating peanut oral immunotherapy in peanut-allergic children under age four may be more effective, first long term study suggests

A randomised controlled trial found that most young children treated with peanut immunotherapy achieved desensitisation after two and a half years of treatment, while one in five remained in remission. Younger children under one year old were more likely to achieve remission, suggesting early interventions may provide better outcomes.

Under elevated CO2 concentration, the increase in CH4 and N2O emissions from paddy fields is decreased with the appropriate agricultural management practices

The study found that elevated CO2 concentration increases CH4 emissions by 23%, but reduces N2O emissions by 22%. However, with longer duration of CO2, emissions decrease by 27% and 53%. Appropriate agricultural management practices, such as straw incorporation and water regimes, also affect these emissions.

Nano-sized vesicles with ACE2 receptor could prevent, treat infection from current and future strains of SARS-CoV-2

Scientists at University of Texas M. D. Anderson Cancer Center and Northwestern Medicine identified naturally occurring vesicles containing ACE2 protein in patients' blood that can prevent or treat SARS-CoV-2 infection. These evACE2 act as decoys to lure the virus away from cells, preventing infection.
