Study may lead to new therapies to improve survival in septic patients

Each year, some 270,000 Americans die from sepsis, in which the release of normally helpful infection-fighting chemicals in the body triggers an unusually extreme immune response - powerful enough to cause life-threatening damage to blood vessels and organs.

Researchers are working to advance device for detecting ultra-low levels of disease particles

In Judith Su's Little Sensor Lab, researchers are working to sense tiny amounts - down to a single molecule - of everything from doping agents to biomarkers for cancer, Alzheimer's disease, Lyme disease and, yes, even COVID-19.

Cancer-killing T cells release chemicals to direct swarms towards tumors

When immune system T cells find and recognise a target, they release chemicals to attract more T cells which then swarm to help subdue the threat, shows a new study published today in eLife.

Researchers identify a promising method to stop COVID-19 infection

While the world waits eagerly for a safe and effective vaccine to prevent infections from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus behind the COVID-19 pandemic, researchers also are focusing on better understanding how SARS-CoV-2 attacks the body in the search for other means of stopping its devastating impact.

Cannabinoids can contribute to negative respiratory health events in older adults with COPD

Cannabinoids, a class of prescription pills that contain synthetically-made chemicals found in marijuana, are associated with a 64 per cent increase in death among older adults with chronic obstructive pulmonary disease (COPD), according to the first published data on the impact of cannabinoids on the respiratory health of individuals with the lung disease.
