Older women are at higher risk for developing breast cancer than younger women are—almost half of all breast cancer cases, and most breast cancer deaths, occur in women who are 65 or older. Despite this, we know very little about how breast cancer and its treatments affect older women. In particular, we don’t fully understand

A new study led by Carnegie Mellon University neuroscientists provides the first evidence of how the human brain recovers the ability to function after losing parts of the visual system. Published in Cell Reports, the researchers report on three years of behavioral and brain imaging tests on a nearly seven year-old boy—”UD”—who had a third

Adult rats that had been exposed before birth and during nursing to a mixture of chemicals found in a wide range of consumer products have a smaller medial prefrontal cortex (mPFC) and perform worse on an attention-switching task than rats not exposed to the chemicals early in life. These findings, published in JNeurosci, demonstrate a

Researchers at the RIKEN Center for Brain Science in Japan have discovered that a gene associated with human intellectual ability is necessary for normal memory formation in mice. Published in Nature Neuroscience, the study shows that mice with only one copy of the gene replay shorter fragments of their previous experiences during periods of rest,

Researchers from Washington State University have discovered how a genetic mutation linked to hypertrophic cardiomyopathy (HCM) disrupts the heart’s normal function. The study, which will be published May 18 in the Journal of General Physiology, reveals that the mutation prevents the heart from increasing the amount of force it produces when it needs to pump

Several studies have found that height and general cognitive ability, or intelligence, are positively associated. A recent study reveals a biological factor underlying this relationship: the size of the cerebral cortex. Reports from several studies have identified a link between height and general cognitive ability, or intelligence, but the mechanisms underlying this association are not

(HealthDay)—For patients with peripheral artery disease (PAD), a home-based exercise intervention does not improve walking ability over nine months compared with usual care, according to a study published in the April 24 issue of the Journal of the American Medical Association.
