New study: US ranks last among other industrialized nations on preventable deaths

The United States places last among 19 countries when it comes to deaths that could have been prevented by access to timely and effective health care, according to new research supported by the Commonwealth Fund and published in the January/February issue of Health Affairs. While other nations dramatically improved these rates between 1997-98 and 2002-03, the US improved only slightly.

New treatment mechanisms for schizophrenia

The field of schizophrenia research has come alive with many exciting new potential approaches to treatment. From the introduction of chlorpromazine to the current day, all treatments approved by the US Food and Drug Administration have had, at their core, a single treatment mechanism, the blockade of the dopamine D2 receptor.

New York City death rate reaches historic low

The death rate in New York City reached an all-time low in 2006, as the number of deaths fell to 55,391 -- down from 57,068 in 2005 and 60,218 in 2001. Mortality declined in eight leading categories, including diabetes, HIV, chronic lung disease and kidney failure. The only leading killer that increased significantly was substance use (up 8 percent).

News tips from the Journal of Neuroscience

The following articles will be featured in the upcoming issue of the Journal of Neuroscience: "Role of TRP3C Channels in Motor Control"; "Long-Range Axonal Targeting in the Adult CNS"; "pH-Mediated Negative Feedback in Inhibitory-Surround Formation"; and "Evidence for Dopamine Toxicity in Neurodegeneration."

NIAID experts see dengue as potential threat to US public health

A disease most Americans have never heard of could soon become more prevalent if dengue, a flu-like illness that can turn deadly, continues to expand into temperate climates and increase in severity, according to a new commentary by Anthony S. Fauci, M.D., director of NIAID, and David M. Morens, M.D., Fauci’s senior scientific advisor. Their commentary appears in the Jan. 9 and 16 double issue of...

Other highlights in the Jan. 8 JNCI

Also in the Jan. 8 JNCI are an association between statin use and reduced cancer risk, a potential colon cancer drug target, a mouse model for studying kidney cancer, and a review of how tumor viruses regulate telomeres.

Protein power: Researchers trigger insulin production in diabetic mice

University of Florida researchers have coaxed liver and pancreatic cells within diabetic mice into churning out insulin by injecting the animals with a naturally occurring protein called Pdx1, opening up a new research avenue that someday could lead to safer treatments for type 1 diabetes. Pdx1 activates the genes controlling the development of the pancreas cells that make and release insulin to...

Research sheds light on the mechanics of gene transcription

The molecular machinery behind gene transcription isn't stationed in special "transcription factories" within a cell nucleus, say to Cornell University researchers. Instead, the enzyme RNA polymerase II and other key molecules can assemble at the site of an activated gene, regardless of the gene's position.

Rutgers, Penn State astronomy teams discover ancestors of Milky Way-type galaxies

Rutgers and Penn State astronomers have discovered galaxies in the distant universe that are ancestors of spiral galaxies like our Milky Way. They are quite small -- one-tenth the size and one-twentieth the mass of our Milky Way, and have fewer stars -- one-fortieth as many as are in the Milky Way. Several of these galaxies, sometimes 10 or more, pulled together over the ensuing few billion years...

Scientists detect lowest frequency radar echo from the moon

A team of scientists from the Naval Research Laboratory, the Air Force Research Laboratory's Research Vehicles Directorate, Kirtland Air Force Base, N.M., and the University of New Mexico has detected the lowest frequency radar echo from the moon ever seen with earth-based receivers.

Scientists unravel the molecular basis of monarch butterfly migration

In two papers published in Jan. 8 journals of the Public Library of Science, Dr. Steven Reppert and colleagues describe a novel circadian clock mechanism in monarch butterflies that is important for accurate navigation, and reveal for the first time a genomic resource for identifying the genes involved in monarch migration.

Smithsonian researcher probes Hope Diamond's fiery red glow

A study released in the January 2008 edition of the journal Geology proves that a blue diamond's rare appeal goes far beyond its beauty. The study was conducted by Jeffrey Post, curator of the National Gem Collection and mineralogist, at the Smithsonian's National Museum of Natural History. Post and six other researchers probed the mysterious phosphorescence of the Hope Diamond and other natural...

Staying active and drinking moderately is the key to a long life

People who drink moderate amounts of alcohol and are physically active have a lower risk of death from heart disease and other causes than people who don't drink at all, according to new research published in the European Heart Journal. People who neither drink alcohol nor exercise have a 30 to 49 percent higher risk of heart disease than those who either drink, exercise or both.

Stimulating the appetite can lead to unrelated impulse purchases

Exposure to something that whets the appetite, such as a picture of a mouthwatering dessert, can make a person more impulsive with unrelated purchases, finds a study from the February 2008 issue of the Journal of Consumer Research. For example, in one experiment the researchers reveal that the aroma of chocolate chip cookies can prompt women on a tight budget to splurge on a new item of clothing.

Study proves the co-pay connection in chronic disease

As 2008 begins, millions of Americans are facing higher insurance co-pays for drugs and doctor appointments. But a new study finds that instead of going up, co-pays should go down -- at least for some people taking some drugs. For people with chronic diseases, a few dollars can make all the difference when deciding to buy key preventive medicines.

Sub-Saharan Africa: the population emergency

With the aim of assessing the significance of relations between population trends and development in Sub-Saharan Africa, the Centre Population et Développement has undertook a wide-ranging survey and produce a review of the demographic situation and dynamics in this vast region. The results, recently published, showed that only combined actions, embracing such aspects as education, health and...

True story? Men prefer 'chick flicks' when they are explicitly fictionalized

Characterized by a heart-tugging plot, emotional melodrama fosters deep emotional reactions on the part of the consumer. Often labelled "chick-flicks," "tearjerkers," or "human interest stories," the genre has received scant academic attention. New research finds a significant difference between how men and women view stories about protagonists who overcome challenges through sacrifice and...

Trying to stay on a strict diet? Focus on the details

Repetition usually makes people enjoy things less. Such satiation causes our favorites to lose their sheen, makes it hard to follow a diet, and pushes us to escalate our spending on novelty. Life has even been called a "hedonic treadmill" where we must find better and better experiences just to stay happy. However, new research from the February issue of the Journal of Consumer Research finds that...
