Early BPA Exposure Linked to Later Food Intolerance

October 30, 2014 2:00 pm | by Federation of American Societies for Experimental Biology | News | Comments

Scientists have shown that there is a link between perinatal exposure to BPA at low doses and the risk of developing food intolerance in later life. This research, involving rats, suggests that early life exposure at a dose significantly below the current human safety limit set by the FDA affects developing immune systems, predisposing offspring to food intolerance in adulthood.

Google Working on Cancer-detecting Pill

October 29, 2014 7:00 am | by Associated Press, Brandon Bailey | News | Comments

Google's latest "moonshot" project involves detecting cancer by swallowing a pill. The pill is packed with tiny magnetic particles, which can travel through a patient's bloodstream, search for malignant cells and report their findings to a sensor device that you wear.

High Milk Diet Linked to Health Problems, Death

October 29, 2014 7:00 am | by British Medical Journal | News | Comments

A high milk intake in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death, suggests observational research. This may be explained by the high levels of lactose and galactose in milk, which have been shown to increase oxidative stress and chronic inflammation in animal studies.

CDC, Army, Governors All Disagree on Ebola Policies

October 28, 2014 2:00 pm | by Associated Press, David Porter, Colleen Barry | News | Comments

The CDC has recommended new restrictions for people at highest risk for coming down with the Ebola virus and symptom monitoring for those at lower risk, but some state governors and even the Army are carving their own paths. The CDC's recommendations mark an effort to create a national standard, one that would protect public health without discouraging people from helping fight its spread overseas.

Tea, Citrus Linked to Lower Cancer Risk

October 28, 2014 2:00 pm | by University of East Anglia | News | Comments

Tea and citrus fruits and juices are associated with a lower risk of developing ovarian cancer, according to new research. Research reveals that women who consume foods containing flavonols and flavanones significantly decrease their risk of developing epithelial ovarian cancer, the fifth-leading cause of cancer death among women.

Ultrasounds Help Kids with Speech Impediments

October 28, 2014 7:00 am | by New York Univ. | News | Comments

Using ultrasound technology to visualize the tongue’s shape and movement can help children with difficulty pronouncing “r” sounds, according to a small study. The ultrasound intervention was effective when individuals were allowed to make different shapes with their tongue in order to produce the “r” sound, rather than being instructed to make a specific shape.

Researchers Learn How Cells Sense, Respond to Chemicals

October 28, 2014 7:00 am | by Johns Hopkins Medicine | Videos | Comments

Amoebas aren’t the only cells that crawl: movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies, researchers have answered long-standing questions about how complex cells sense the chemical trails that show them where to go— and the role of cells’ internal “skeleton” in responding to those cues.
