Better batteries

Researchers at Northwestern University have created an electrode that allows lithium-ion batteries to hold a charge up to 10 times greater than current technology. The new technology can also charge 10 times faster, paving the way for more efficient and smaller batteries for electric cars.

Girls with family history of breast disease should avoid alcohol

A new study from Washington University School of Medicine finds that adolescent girls with a family history of breast disease have a higher risk of developing benign breast disease as young women, and this risk rises with increasing alcohol consumption. The researchers suggest limiting alcohol intake to lower risk or avoid increasing it.

Poor sleep habits linked to increased risk of fibromyalgia in women

A longitudinal study published in Arthritis & Rheumatism found a strong association between poor sleep habits and the risk of developing fibromyalgia in women. The study, which followed over 12,000 women for ten years, found that women with severe sleep problems were at increased risk of developing fibromyalgia.

Eliminating co-payments for heart attack medications increases adherence

A study by Brigham and Women's Hospital found that eliminating copayments for heart attack medications increased patient adherence, reducing major vascular events and healthcare spending. Rates of combined endpoint were not significantly improved, but individual outcomes such as readmission and angina showed significant reductions.

Glioblastoma multiforme in the Dock

A study by Bo Hu and Shi-Yuan Cheng found that PDGFR-alpha overexpression in glioblastomas triggers a signaling cascade promoting tumor growth and invasion. Manipulating Dock180 to block this pathway inhibits PDGFR-alpha's role in glioma tumorigenesis.

'Stomach flu' may be linked to food allergies

A study by researchers at the Medical College of Wisconsin suggests a possible link between norovirus and food allergies. The team found an immunoglobulin E response to egg protein in mice infected with norovirus, indicating a potential connection between gastrointestinal viruses and allergic diseases like asthma.

NIH-funded twin study finds occupational chemical exposure may be linked to Parkinson's risk

A recent NIH-funded twin study found a significant link between occupational chemical exposure and the development of Parkinson's disease. The study, published in Annals of Neurology, suggests that two common solvents, trichloroethylene (TCE) and perchloroethylene (PERC), may increase Parkinson's risk sixfold and ninefold, respectively...

Adolescent alcohol consumption and breast cancer

A new study found a significant association between adolescent alcohol consumption and increased risk of benign breast disease among girls with a family history of breast cancer. Consuming more alcohol was linked to a higher risk, particularly in those with rapid height growth spurts.

Enzyme boosts metabolism, prevents weight gain in mice

Scientists engineer mice to express human enzyme IKKbeta in fat tissue, significantly slowing weight gain and improving metabolism. The study suggests obesity is worse than inflammation for insulin resistance, offering new clues about the connections among obesity, inflammation, and type 2 diabetes.

JCI online early table of contents: Nov. 14, 2011

Researchers discovered a molecular pathway driven by PDGFR-alpha that promotes the aggressive nature of a significant proportion of glioblastomas. Overexpressed in GBMs, this pathway triggers signaling cascades leading to tumor growth and invasion. Manipulating Dock180 phosphorylation disrupts this pathway, resulting in failed tumor pr...
