MADISON — Researchers may have pinpointed a reason many smokers struggle to quit. According to new research published in the journal Addiction, smokers with a history of anxiety disorders are less likely to quit smoking. The study, conducted by the University of Wisconsin Center for Tobacco Research and Intervention (UW-CTRI), offered free coaching and medications to smokers in Madison and Milwaukee.

While overall quit rates for the study were high, participants with anxiety diagnoses were much less likely to quit smoking.

A new study in the Journal of General Physiology (JGP) shows that the contribution of odorant receptors (ORs) to olfactory response in mammals is much more complex than previously thought, with important consequences for odorant encoding and information transfer about odorants to the brain. The study appeared online October 25th.

Immune cells deploy traps to catch and kill pathogens

A new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unraveling and using the chromatin (DNA and its associated proteins) contained in the cells' nuclei to form defensive webs. The study appears online on October 25 in The Journal of Cell Biology (www.jcb.org).

PROVIDENCE, R.I. [Brown University] — Fertility procedures such as in vitro fertilization (IVF) require a couple and the doctor to place the risky bet that the multiple eggs they choose to fertilize will produce an embryo that will thrive in the uterus. Researchers cannot biopsy eggs directly because that would destroy them, but a new discovery by professors at Brown University and Women & Infants Hospital could lead to new insights about how eggs develop and ultimately inform judgments about how the embryos they produce will fare.

A team of researchers, led by Ashley Moffett, at the University of Cambridge, United Kingdom, has shed new light on genetic factors that increase susceptibility to and provide protection from common disorders of pregnancy, specifically recurrent miscarriage, preeclampsia, and fetal growth restriction.

In scientific publishing, how much reuse of text is too much? Researchers at the Virginia Bioinformatics Institute at Virginia Tech and collaborators have shown that a computer-based text-searching tool is capable of unearthing questionable publication practices from thousands of full-text papers in the biomedical literature.

Laxenburg, Austria – 26th October 2010 --A new assessment of future scenarios that limit the extent of global warming cautions that unless current imbalances in R&D portfolios for the development of new, efficient, and clean energy technologies are redressed, greenhouse gas (GHG) emission reduction targets are unlikely to be met, or met only at considerable costs.

BOSTON (October 25, 2010) — Researchers from Tufts University pooled data from five previous epidemiological studies to investigate the prevalence of asthma in children in the Boston neighborhoods of Chinatown and Dorchester. Among children born in the United States, low socioeconomic status (SES) and exposure to pests (mice and cockroaches) were both associated with having asthma. Neither association was present in children born outside of the United States. The study was published online in advance of print in the Journal of Immigrant and Minority Health.

Flamingos apply natural make-up to their feathers to stand out and attract mates, according to a new study by Juan Amat, from the Estación Biológica de Doňana in Seville, Spain, and colleagues. Their research is the first to demonstrate that birds transfer the color pigments (carotenoids) from the secretions of their uropygial gland for cosmetic reasons. The uropygial or preen gland is found in the majority of birds and is situated near the base of the tail. The study is published online in Behavioral Ecology and Sociobiology, a Springer journal.

Daily vibration may help aging bones stay healthy

AUGUSTA, Ga. - A daily dose of whole body vibration may help reduce the usual bone density loss that occurs with age, Medical College of Georgia researchers report.

A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests.

Researchers have isolated and grown stem cells from a yew tree whose bark is a natural source of the anticancer compound paclitaxel. The development could enable the compound to be produced on a commercial scale at low cost, with no harmful by-products.

They are one of the most highly prized delicacies in the culinary world, but now scientists have discovered that black truffles are locked in a gender war for reproduction. The research, published in New Phytologist as the truffle season begins, represents a breakthrough in the understanding of truffle cultivation and distribution.

A child's chances of developing allergies or wheezing is related to how he or she grew at vital stages in the womb, according to scientists from the University of Southampton.

The new research, funded by the Medical Research Council (MRC) and the British Lung Foundation, and undertaken at Southampton General Hospital, reveals that fetuses which develop quickly in early pregnancy but falter later in pregnancy are likely to go on to develop allergies and asthma as children. Scientists believe this is due to changes in the development of their immune system and lungs.
