Vitamin D deficiency in infants and nursing mothers carries long-term disease risks

New Rochelle, NY, December 16, 2008—Once believed to be important only for bone health, vitamin D is now seen as having a critical function in maintaining the immune system throughout life. The newly recognized disease risks associated with vitamin D deficiency are clearly documented in a report in the December issue (Volume 3, Number 4) of Breastfeeding Medicine, a peer-reviewed journal published by Mary Ann Liebert, Inc.

Unpasteurized milk poses health risks without benefits

With disease outbreaks linked to unpasteurized milk rising in the United States, a review published in the January 1, 2009 issue of Clinical Infectious Diseases examines the dangers of drinking raw milk.

UIC researchers hunting drugs for devastating parasitic disease

Hundreds of millions of people, mainly in developing countries, are disabled by infectious diseases, according to the World Health Organization.

More than 12 million people in 88 countries are infected with leishmaniasis, a parasitic disease spread by the bite of infected sand flies. Nearly 2 million new cases are reported and about 70,000 people die from the disease annually.

Researchers at the University of Illinois at Chicago have discovered that compounds derived from a natural product can be used in developing a new drug to treat the disease.

Benefits of breastfeeding outweigh risk of infant exposure to environmental chemicals in breastmilk

New Rochelle, NY, December 16, 2008—A study comparing breastfed and formula fed infants across time showed that the known beneficial effects of breastfeeding are greater than the potential risks associated with infant exposure to chemicals such as dioxins that may be present in breastmilk, according to a report published in the December issue (Volume 3, Number 4) of Breastfeeding Medicine, a peer-reviewed journal published by Mary Ann Liebert, Inc.

Big-3 bankruptcy: Job loss less than half oft-cited figure, says UM study

COLLEGE PARK, Md. – The impact of a Big-3 bankruptcy and restructuring would be severe, but frequently-quoted job loss figures are misleading and overstated, according to a new projection by the University of Maryland's Inforum economic research unit. In the worse case scenario, peak job dislocation from restructuring would be half of the 3 million commonly cited in the media. http://www.inforum.umd.edu/index.html

Real-time gene monitoring developed

Imagine having GeneVision: the uncanny ability to view the activity of any chosen gene in real time through a specially modified camera.

With GeneVision, military commanders could compare gene expression in victorious and defeated troops. Retailers could track genes related to craving as shoppers moved about a store. "The Bachelor" would enjoy yet one more secret advantage over his love-struck dates.

Frightening? Perhaps. Ethically suspect? Certainly. Preposterous? Not quite.

Both theories about human cellular aging supported by new research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.

These research findings, presented at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco, support the theories that old age is the final stage of a developmental program AND the result of a lifelong accumulation of unrepaired cellular and molecular damage.

Evolutionary roots of ancient bacteria may open new line of attack on CF

The redox-active pigments responsible for the blue-green stain of the mucus that clogs the lungs of children and adults with cystic fibrosis (CF) are primarily signaling molecules that allow large clusters of the opportunistic infection agent, Pseudomonas aeruginosa, to organize themselves into structured communities, report Massachusetts Institute of Technology geobiologists at American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Researchers discover new way men can transmit HIV to women

CHICAGO --- Researchers at Northwestern University have discovered a critical new way a man can transmit the HIV virus to a woman.

Scientists had long believed that the normal lining of the female vaginal tract was an effective barrier to invasion of the HIV virus during sexual intercourse. They thought the large HIV virus couldn't penetrate the tissue.

Pitt researchers create non-toxic clean-up method for potentially toxic nano materials

PITTSBURGH—University of Pittsburgh researchers have developed the first natural, nontoxic method for biodegrading carbon nanotubes, a finding that could help diminish the environmental and health concerns that mar the otherwise bright prospects of the super-strong materials commonly used in products, from electronics to plastics.

Caltech researchers interpret asymmetry in early universe

PASADENA, Calif.--The Big Bang is widely considered to have obliterated any trace of what came before. Now, astrophysicists at the California Institute of Technology (Caltech) think that their new theoretical interpretation of an imprint from the earliest stages of the universe may also shed light on what came before.

Genes involved in antibiotic resistance vary within a species

CLEVELAND – December 16, 2008 – The recent emergence of multidrug resistance (MDR) in Acinetobacter baumannii, a bacteria that causes infections primarily among seriously ill patients in the intensive care unit who may have reduced immune systems, has raised concern in health care settings worldwide. When comparing the genome sequence of three MDR A. baumannii isolates and three drug-susceptible A.

'Don't drink and ride': Improving subway safety

December 16, 2008 -- Structural interventions and public safety messages may be the most effective ways to prevent subway fatalities and improve the overall safety of New York City subway systems, according to a study by researchers at Columbia University's Mailman School of Public Health. Subway safety is important because even though subway transit is a relatively safe mode of transportation, it has the highest fatality rate of all forms of mass transit in the U.S.

Quiet bison sire more calves than louder rivals

During bison mating season, the quietest bulls score the most mates and sire the most offspring while studs with the loudest bellows see the least action, according to a surprising new study by researchers at University of California, Davis, and Point Loma Nazarene University in San Diego. The researchers also found that the volume of a bull's bellow was not related to its weight or age.

New satellite data reveal impact of Olympic pollution controls

Chinese government regulators had clearer skies and easier breathing in mind in the summer of 2008 when they temporarily shuttered some factories and banished many cars in a pre-Olympic sprint to clean up Beijing's air. And that's what they got.

They were not necessarily planning for something else: an unprecedented experiment using satellites to measure the impact of air pollution controls. Taking advantage of the opportunity, NASA researchers have since analyzed data from NASA's Aura and Terra satellites that show how key pollutants responded to the Olympic restrictions.
