Cell growth and death controlled by single pathway in lymphoma cancer model

A study by Rockefeller University researchers reveals that a single molecular pathway controls both cell growth and death in a type of lymphoma cancer. The NF-kappa B signaling pathway, responsible for promoting cell growth, also regulates the p53 tumor suppressor protein's function, which normally destroys harmful cells.

ICU physicians save hospitals money

The study found annual cost savings ranging from $510,000 to $13 million for different ICU bed sizes, with a best-case scenario demonstrating up to $4.2-$13 million in savings. Implementing intensivist staffing can also reduce hospital mortality by 30% and potentially save 162,000 lives annually.

NCAR instrument gets breakthrough view of Sun's magnetic halo

The NCAR instrument provides unprecedented views of the solar corona's magnetic structures, enabling scientists to analyze magnetism in the corona and relate it to emerging features like prominences and coronal mass ejections. This data will aid space weather forecasters in predicting solar storms that can impact Earth's infrastructure.
