Mechanism discovered that can send cells on the road to cancer

Using a common virus as a tool for investigating abnormal cell proliferation, a team led by scientists at Cold Spring Harbor Laboratory (CSHL) has succeeded in clarifying an intricate series of biochemical steps that shed light on a way that cancer can begin.

Predicting astronauts from radiation

European scientists have developed the most accurate method yet for predicting the doses of radiation that astronauts will receive aboard the orbiting European laboratory module, Columbus, attached to the ISS this week.

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer

Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.

Sounds can alter how masculine or feminine a person looks

Think about the confused feelings that occur when you meet someone whose tone of voice doesn't seem to quite fit with his or her gender.

Overexposure to metals and Alzheimer's disease

A multi-institutional team of researchers led by Emory University has defined for the first time how metal ions bind to amyloid fibrils in the brain in a way that appears toxic to neurons.

Novel type of communication between nerve cells in the brain discovered

The findings may have relevance for the prevention and treatment of epilepsy, and possibly in the exploration of other aspects of brain functions, from creative thought processes to mental illnesses such as schizophrenia.

New insights into prion propagation

Prions - infectious, oddly-folded proteins that are the main suspects in fatal neurodegenerative diseases such as Cruetzfeldt-Jakob and bovine spongiform encephalopathy, or "mad cow" - remain mostly a mystery to scientists.

Nitric oxide may be the key to why specific drugs for heart failure or asthma lose their effectiveness over time

A naturally occurring molecule in the body appears to control whether certain medications, such as beta adrenergic receptor agonists used in acute heart failure or in inhalers for asthma, lose their effectiveness over time.

New method allows for stem cell propagation and neurogenesis in cell culture

Researchers are now able to study stem cells from the brains of adult mice and their neurogenesis in long-term cell cultures.

New discoveries about stem cells in leukemia, breast and colon cancer

Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research. With each new study, scientists are learning more about cancer-initiating properties of stem cells at organ sites and throughout the body.

Cell structures exhibit novel behaviors, mimic red blood cells and liquid crystals

Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.

Inhaled corticosteroids deserve further consideration for lung cancer chemoprevention

Among a group of mostly older male veterans suffering from chronic obstructive pulmonary disease (COPD), an illness that offers a greater susceptibility to lung cancer, researchers found that regular use of high dose inhaled corticosteroids (ICS) lowered the risk of developing lung cancer.
