Researchers at Memorial Sloan Kettering Cancer Center (MSK) and their colleagues have discovered that a type of rogue DNA found in aggressive cancers has a hidden structural weakness—and that blocking a single repair protein can cause it to fall apart, suggesting a new therapeutic opportunity.

Stroke is becoming more common among younger adults, according to a study published in Neurology. Researchers found that strokes among adults ages 20 to 54 nearly doubled over nearly three decades, even as short-term survival after stroke improved.

A systematic review of the scientific literature on mobile phone use during pregnancy and fetal outcomes examines the potential health effects of exposure. While some studies included in the review found no significant association between short- or long-term mobile phone use and major pregnancy outcomes, most associated prolonged or intensive use with a range of adverse outcomes, particularly cardiovascular abnormalities and shorter gestational duration.

Having a transient ischemic attack (TIA) is associated with an increased risk of developing dementia, according to a new study published in Neurology. The study does not prove that a transient ischemic attack causes dementia; it only shows an association.

In a study focused on aggressive breast and pancreatic cancers, scientists have discovered how tumors surrounded by a protective “scaffold” of dense, scar-like tissue manage to thrive—despite the scaffold severely restricting the blood supply and nutrient delivery essential for growth.
