Life Expectancy Highly Correlated with Telomere Length and Dynamics

Studying a bird model in the wild, scientists have for the first time found telomere length and dynamics to be highly predictive of “biological” age and life expectancy for individuals in a given population. More...

Bacterial Quorum Sensing Molecule Targets Host Cell Migration Receptor

Scientists have discovered a new role and important target on human host cells for a signaling molecule known for its role in quorum sensing of the pathogenic bacteria Pseudomonas aeruginosa. More...

New Mole Rat Cancer Resistance Pathway Discovered

In a study of a species of mole rats, biologists have identified a cancer resistance mechanism different from another long-lived, cancer-resistant mole rat species discovered earlier. More...

Hormone Therapy Response Associated with Signaling Activity in Circulating Cancer Cells

A study monitoring hormone receptor activity in tumor cells from patients being treated for resistant metastatic prostate cancer has found that such monitoring may be useful for indicating which patients will be more likely to respond well to continued therapy. More...

Diabetes Drug Decreases Psychostimulant Addiction Behavior

Researchers report a drug currently used for the medical management of type 2 diabetes could also be effective for treating addiction to often-abused psychostimulants. More...

Metabolic Incentives to Cooperate Controlled by Bacterial Quorum Sensing

Scientists have found that bacterial quorum sensing controls when and which cells in a given population will release “public goods” into their environment, and does so in a way that is at least partly achieved by specific metabolic advantage “incentives” for the individual cells. More...

Curcumin Also Inhibits Metastasis from Prostate Cancer

Researchers have now shown that curcumin, the key medicinal ingredient of turmeric, can also inhibit formation of metastases from prostate cancer, and have identified the main mechanism by which it does so. More...
