Mitochondria Drive Cell Survival in Times of Need

The research, published in Molecular Cell, builds on previous work by McGill professor Nahum Sonenberg, one of the senior authors of the new study. Cells in our body grow in size, mass and numbers through a process governed by a master regulator known as mTOR (Mechanistic Target of Rapamycin). Sonenberg discovered years

A Tiny Device Offers Insights to How Cancer Spreads

What if there were a way to find those early aggressors? How are they different from the rest of the cells? And more importantly: Is there a way to stop them before they spread? These questions drove a team of researchers at the University of Michigan Comprehensive Cancer Center and Michigan

Zika Virus Kills Brain Cancer Stem Cells

The findings suggest that the lethal power of the virus -- known for infecting and killing cells in the brains of fetuses, causing babies to be born with tiny, misshapen heads -- could be directed at malignant cells in the brain. Doing so potentially could improve people's chances against a

Motorized Molecules Drill Through Cells

Researchers at Rice, Durham (U.K.) and North Carolina State universities demonstrated in lab tests how rotors in single-molecule nanomachines can be activated by ultraviolet light to spin at 2 to 3 million rotations per second and open membranes in cells. The researchers used motors based on work by Nobel laureate Bernard

Chemo-Boosting Drug Discovered for Leukemia

In a study published in Cancer Cell, researchers at the Francis Crick Institute, King's College London and Barts Cancer Institute discovered that acute myeloid leukemia (AML) - the most common acute leukemia affecting adults - causes bone marrow to 'leak' blood, preventing chemotherapy from being delivered properly. Drugs that reversed bone

Brain Cells Found to Control Aging

The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the cells in the hypothalamus that control aging: a tiny population of adult
