New Mutations Found in Most Common Form of Lung Cancer

July 9, 2014 3:54 pm | News | Comments

Researchers have identified novel mutations in a well-known cancer-causing pathway in lung adenocarcinoma, the most common subtype of lung cancer. Knowledge of these genomic changes may expand the number of possible therapeutic targets for this disease and potentially identify a greater number of patients with treatable mutations because many potent cancer drugs that target these mutations already exist.

Not at Home on the Range

July 9, 2014 3:44 pm | News | Comments

As climate change shifts the geographic ranges in which animals can be found, concern mounts over the effect it has on their parasites. Does an increased range for a host mean new territory for its parasites as well? Not necessarily, says a team of UC Santa Barbara scientists.

Tiny DNA Pyramids Enter Bacteria Easily and Deliver a Deadly Payload

July 9, 2014 11:53 am | News | Comments

Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics—and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids. Their study found the nanopyramids can flag bacteria and kill more of them than medicine alone.

Obesity Can Cut Up to 14 Years from Life Expectancy

July 9, 2014 11:09 am | News | Comments

Adults with extreme obesity have increased risks of dying at a young age from cancer and many other causes including heart disease, stroke, diabetes, and kidney and liver diseases, according to results of a new analysis.         

Cinnamon Could Halt Progression of Parkinson’s

July 9, 2014 10:26 am | News | Comments

Neurological scientists have found that using cinnamon, a common food spice and flavoring material, can reverse the biomechanical, cellular and anatomical changes that occur in the brains of mice with Parkinson’s disease (PD).       

Forgotten Vials of Smallpox Found in Storage Room

July 9, 2014 8:30 am | by Mike Stobbe, AP Medical Writer | News | Comments

A government scientist cleaning out an old storage room at a research center near Washington made a startling discovery last week- decades-old vials of smallpox packed away and forgotten in a cardboard box.

Protein Discovery is Step Toward Blood Test for Alzheimer's

July 8, 2014 12:27 pm | News | Comments

Scientists have identified a set of 10 proteins in the blood which can predict the onset of Alzheimer’s, marking a significant step towards developing a blood test for the disease.                     

Neandertal Trait Found in Ancient Skull Raises New Evolution Questions

July 8, 2014 12:02 pm | News | Comments

Re-examination of a circa 100,000-year-old archaic early human skull found 35 years ago in Northern China has revealed the surprising presence of an inner-ear formation long thought to occur only in Neandertals.           

Low Doses of Arsenic Cause Cancer in Mice

July 8, 2014 11:50 am | News | Comments

Mice exposed to low doses of arsenic in drinking water, similar to what some people might consume, developed lung cancer, researchers have found. Arsenic is present in the environment as a naturally occurring substance or due to contamination from human activity.

July 8, 2014 11:00 am | News | Comments

Samples isolated from Chobani yogurt that was voluntarily recalled in September 2013 have been found to contain the most virulent form of a fungus called Mucor circinelloides, which is associated with infections in immune-compromised people.   

First Cancer Immunotherapy for Dogs Developed

July 7, 2014 2:51 pm | News | Comments

A few therapies derived from human medicine are available for dogs, but a very successful form of therapy by which antibodies inhibit tumor growth has not yet been available for animals. Now, scientists have developed, for the first time, antibodies to treat cancer in dogs.

Schizophrenia-associated Gene Variation Affects Brain Cell Development

July 7, 2014 2:46 pm | News | Comments

Researchers have begun to connect the dots between a schizophrenia-linked genetic variation and its effect on the developing brain. Their experiments show that the loss of a particular gene alters the skeletons of developing brain cells, which in turn disrupts the orderly layers those cells would normally form.

High Cholesterol Linked to Breast Cancer Risk
