Thwarting Protein Production Slows Cancer Cells’ Malignant March

Whitehead Institute for Biomedical Research

Protein production or translation is tightly coupled to a highly conserved stress response—the heat shock response and its primary regulator, heat shock factor 1 (HSF1)—that cancer cells rely on for survival and proliferation, according to Whitehead Institute researchers. In mouse models of cancer, therapeutic inhibition of translation interrupts HSF1’s activity, dramatically slowing tumor growth and potentially rendering drug-resistant tumors responsive to other therapies.

NASA's Hubble Shows Link Between Stars' Ages and Their Orbits

Space Telescope Science Institute (STScI)

Astronomers using NASA's Hubble Space Telescope have determined the orbital motion of two distinct populations of stars in ancient globular star cluster 47 Tucanae, offering proof they formed at different times and providing a rare look back into the Milky Way galaxy's early days.

Best Romantic Singers Are Male Bats

Texas A&M University

Male bats appear to be the sexy singers of the animal world: they have learned to vocalize in a specific way to attract females, but once they have their attention, they change their tune – literally. They then produce a more creative array of sounds to entertain and keep the females interested.

Bearing Witness to the Phenomenon of Symmetric Cell Division

Whitehead Institute for Biomedical Research

For more than 125 years, scientists have been peering through microscopes, carefully watching cells divide. Until now, however, none has actually seen how cells manage to divide precisely into two equally-sized daughter cells during mitosis. Such perfect division depends on the position of the mitotic spindle (chromosomes, microtubules, and spindle poles) within the cell, and it’s now clear that human cells employ two specific mechanisms during the portion of division known as anaphase to correct mitotic spindle positioning.

Weight Loss Drug Helps Curb Cocaine Addictions

Perelman School of Medicine at the University of Pennsylvania

The drug topiramate, typically used to treat epilepsy and more recently weight loss, may also help people addicted to both cocaine and alcohol use less cocaine, particularly heavy users, researchers in the department of Psychiatry at Penn Medicine report in a new study published in Drug and Alcohol Dependence.
