Scientists create mouse model to track immature T cells' transformation into specialized killer T cells capable of destroying infected or cancerous cells. The research aims to understand how the immune system thwarts T cell functionality in diseases like HIV and cancer.
A mathematical model of H.pylori bacteria and their human hosts reveals the key role played by adherent bacteria in colonization, as well as the dynamic relationship between host response and bacterial persistence. The model sheds light on the complex interactions between the bacteria and human immune system.
Climate models project a 23-30% decline in mountain snowpack by 2025, and up to 61% by 2095. This could drastically alter hydrology and water resource management in the region.
A team of scientists has created a detailed model of the structure of a protein in photosynthetic bacteria, which can help explain how certain diseases such as Alzheimer's and Mad Cow Disease occur. The model shows how nature uses irregular forms to create complex structures that are effective at absorbing sunlight.
Scientists at Boston University report a new model of ventilator assisted lung function that incorporates 'noise' to improve gas exchange in patients with lung injury. The approach may also minimize additional trauma by enhancing the avalanche-like opening of airways and alveoli during inhalation.
David Meyer presents evidence that ancient crinoid Uintacrinus could float using a new model. The model explains the organism's ability to support its weight and collect food particles at the sea surface.
The Stanford research group synthesized a compound that replicates the chemical wizardry of cytochrome c oxidase, a vital biochemical process found in all oxygen-using organisms. The model converts oxygen molecules into water, releasing energy to charge biological batteries and generate heat.
