Researchers identify potential target to delay metastatic pancreatic cancer and prolong survival

PHILADELPHIA -- Often, and without much warning, pancreatic cancer cells slip through the endothelial cells, head into the blood and out to other parts of the body to metastasize, making it one of the deadliest and hardest to treat cancers today. Now, researchers from Thomas Jefferson University's Center for Translational Medicine have found that reducing levels of a well-known, cell-surface protein known as N-cadherin in those cancer cells can interfere with that activity. The disruption slowed down the pancreatic cancer cells' mobility, they found, and prolonged survival ...

Benefits of new air quality rules greatly outweigh costs

A report by researchers at Columbia University's Mailman School of Public Health provides an expanded review of six new air quality regulations proposed or recently adopted by the U.S. Environmental Protection Agency's (EPA). These include the first national standards for reducing dangerous emissions of mercury and other toxic pollutants from power plants. Though the cost of implementing the new regulations is estimated to be about $195 billion over the next 20 years or so, the economic, environmental and health benefits amount to well over $1 trillion, considerably outweighing ...

PET technique promises better detection and response assessment for Non-Hodgkin's lymphoma

Reston, Va. – Positron emission tomography (PET) and a molecular imaging agent that captures the proliferation of cancer cells could prove to be a valuable method for imaging a form of Non-Hodgkin's disease called mantle cell lymphoma, a relatively rare and devastating blood cancer. The pilot study is published in the December issue of the Journal of Nuclear Medicine. Lymphoma is the term used for an array of cancers that affect blood cells and the lymphatic system. These cancers are typically categorized as either Hodgkin's or non-Hodgkin's. Mantle cell lymphoma (MCL) ...

Research states that prejudice comes from a basic human need and way of thinking

Where does prejudice come from? Not from ideology, say the authors of a new paper. Instead, prejudice stems from a deeper psychological need, associated with a particular way of thinking. People who aren't comfortable with ambiguity and want to make quick and firm decisions are also prone to making generalizations about others. In a new article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, Arne Roets and Alain Van Hiel of Ghent University in Belgium look at what psychological scientists have learned about ...

Automobile Title Washing is a Dirty Business

"Title washing" is an emerging form of fraud that allows car owners to take advantage of unwitting car buyers by concealing information on the car's title. It is principally done in one of two ways. Frequently the perpetrators take advantage of varying vehicle documentation laws among different states to hide flood-damaged and salvaged title labels on the car's title. Scammers are also able to dupe victims by filing fraudulent paperwork with the state to obtain a duplicate title that does not show the valid lien attached to a vehicle. Insurance companies brand ...

Long White-Collar Crime Sentences: Do They Really Deter?

Federal prosecutors requested a 385-year sentence for Lee B. Farkas, for his role in a complex bank fraud.

According to Peter Henning, a Wayne State law professor, in a blog for the NY Times, this sentence is a continuation of the development ...

How pregnancy changes a woman's brain

We know a lot about the links between a pregnant mother's health, behavior, and moods and her baby's cognitive and psychological development once it is born. But how does pregnancy change a mother's brain? "Pregnancy is a critical period for central nervous system development in mothers," says psychologist Laura M. Glynn of Chapman University.

Low in the south in the summer sky shines the constellation Scorpius and the bright, red supergiant star Antares. Many of the brightest stars in Scorpius, and hundreds of its fainter stars, are among the youngest stars found near the earth, and a new analysis of them may result in a rethinking of both their ages and the ages of other groups of stars.

UCLA neuroscientists demonstrate crucial advances in 'brain reading'

At UCLA's Laboratory of Integrative Neuroimaging Technology, researchers use functional MRI brain scans to observe brain signal changes that take place during mental activity. They then employ computerized machine learning (ML) methods to study these patterns and identify the cognitive state — or sometimes the thought process — of human subjects. The technique is called "brain reading" or "brain decoding." In a new study, the UCLA research team describes several crucial advances in this field, using fMRI and machine learning methods to perform "brain reading" on smokers ...
