Alzheimer’s disease affects more than 26 million people worldwide. It is predicted to skyrocket as boomers age—nearly 106 million people are projected to have the disease by 2050. Fortunately, scientists are making progress towards therapies. A collaboration among several research entities, including the Salk Institute and the Sanford-Burnham Medical Research Institute, has defined a key mechanism behind the disease’s progress, giving hope that a newly modified Alzheimer’s drug will be effective.
• A protein called polycystin-1 may help shepherd another protein, polycystin-2, to a cell’s antenna, or cilium. This process is defective in induced pluripotent stem cells derived from patients with autosomal dominant polycystic kidney disease. • Placement of the normal polycystin-1 protein back into cells can correct this defect. • Pluripotent stem cells from polycystic kidney patients may be useful as “disease in a dish” models for developing new therapeutics.

Heart attack deaths have remained the same, even as hospital teams have gotten faster at treating heart attack patients with emergency angioplasty, according to a study in this week’s New England Journal of Medicine.
A new, international study from the Chronic Kidney Disease Prognosis Consortium found that use of blood levels of cystatin C to estimate kidney function—alone or in combination with creatinine—strengthens the association between kidney function and risks of death and end-stage renal disease.
A new, international study found that use of blood levels of cystatin C to estimate kidney function—alone or in combination with creatinine—strengthens the association between kidney function and risks of death and end-stage renal disease. The findings suggest that the use of cystatin C as a measurement of kidney function could lead to better staging and risk classification of chronic kidney disease.
University of Utah bioengineers discovered our understanding of language may depend more heavily on vision than previously thought: under the right conditions, what you see can override what you hear.
New research suggests that men who exercise vigorously as young adults may reduce their risk of developing epilepsy later in life. The study is published in the September 4, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Epilepsy is a brain disease that causes repeated seizures over time.
A University of Iowa physiologist has a new technique to measure the stiffness of the aorta, a common risk factor for heart disease. The procedure involves measuring the pulse in the finger or on the arm, combined with an individual's age and body mass index. Results are published in the American Journal of Physiology – Heart and Circulatory Physiology.
Researchers at the Kennedy Krieger Institute announced today study findings showing, for the first time, the link between the brain’s cerebellum and proprioception, or the body’s ability to sense movement and joint and limb position. Published in The Journal of Neuroscience, the study uncovers a previously unknown perceptual deficit among cerebellar patients, suggesting that damage to this portion of the brain can directly impact a person’s ability to sense the position of their limbs and predict movement. This discovery could prompt future researchers to reexamine physical therapy tactics for cerebellar patients, who often have impaired coordination or appear clumsy.
Researchers at Johns Hopkins and the National Institutes of Health have identified a compound that dramatically bolsters learning and memory when given to mice with a Down syndrome-like condition on the day of birth. As they report in the Sept. 4 issue of Science Translational Medicine, the single-dose treatment appears to enable the cerebellum of the rodents’ brains to grow to a normal size.
A new laser-based technology may make brain tumor surgery much more accurate, allowing surgeons to tell cancer tissue from normal brain at the microscopic level while they are operating, and avoid leaving behind cells that could spawn a new tumor.
