CHAMPAIGN, Ill. — Getting an inside look at the center of a cell can be as easy as a needle prick, thanks to University of Illinois researchers who have developed a tiny needle to deliver a shot right to a cell's nucleus.

Intestinal worms sidestep the immune system by inducing the development of suppressive T cells, according to a study published on September 27th in the Journal of Experimental Medicine .

Researchers have shown that LIM kinase (LIMK), an important regulator of actin cytoskeleton dynamics, plays a key role in cancer metastasis. The study appears online on September 27 in The Journal of Cell Biology www.jcb.org.

About ten years ago, the discovery of microRNAs ― tiny cellular molecules that regulate our genetic code ― unlocked a world of scientific possibilities, including a deeper understanding of human disease. One new analytical technology is "deep sequencing," which gives scientists the ability to discover invaluable information about human diseases at a genetic level. Now, Tel Aviv University researchers have developed the cutting-edge technology to better analyze these results.

ROCHESTER, Minn. -- In one of the first studies to focus exclusively on the outcomes after treatment for patients with high-risk prostate cancer,(http://www.mayoclinic.org/prostate-cancer/) researchers have found that surgery provides high survival rates.

While the U.S. has made great progress in the prevention and treatment of tuberculosis, the nation has become more susceptible to potential epidemics of multidrug-resistant tuberculosis (MDR-TB), according a study led by Johns Hopkins researchers. Computer simulations show that as TB prevalence falls, the risk for more extensive MDR-TB increases. In addition, the simulation also showed that higher detection of TB cases without proper treatment of cases also increased risk.

Flowering plants produce nectar to attract insect pollinators. Some plant species, such as Lima bean, also secrete nectar from so-called extrafloral nectaries to attract ants which in turn fend off herbivores. Scientists of the Max Planck Institute in Jena, Germany, have discovered that the production of extrafloral nectar is light dependent. They have shown that the plants are able not only to distinguish between day and night, but also to adapt their nectar secretion to current light conditions by using a special photoreceptor, the phytochrome.

A recent study undertaken by investigators at five research centres, amongst which is the CSIC-University of the Basque Country Biophysics Unit, provides new clues for the understanding of the 'cell suicide' process. The research was published in the latest issue of the prestigious Cell journal.

DAKAR, SENEGAL (27 September 2010)—A long neglected crop with the potential to halt hunger for millions in Africa, sustain the livestock revolution underway in developing countries, rejuvenate nutrient-sapped soils, and even feed astronauts on extended space missions, is attracting scientists from around the world to Senegal this week for the Fifth World Cowpea Research Conference.

A report presented today by Health and Consumer Policy Commissioner John Dalli to the Agriculture Council concludes that specific measures relating to storing and the application of isolation distances can help limit or avoid the co-mingling of genetically modified (GM) maize with conventional and organic maize. In particular, the Best Practice Document, prepared by the European Coexistence Bureau (ECoB) and published by the European Commission's Joint Research Centre (JRC), notes that storing seeds adequately and applying spatial isolation are the best ways to limit or avoid co-mingling.

A new analysis finds that men whose partners have breast cancer are at increased risk of developing mood disorders that are so severe that they warrant hospitalization. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study indicates that clinicians should address the mental health of cancer patients' loved ones.

Working to solve the puzzle of when people develop celiac disease has led researchers from the University of Maryland School of Medicine Center for Celiac Research to some surprising findings. They have found that the autoimmune disorder is on the rise with evidence of increasing cases in the elderly. An epidemiological study published September 27 in the Annals of Medicine supports both trends—with interesting implications for possible treatment and prevention.

Exposure to common viruses in daycare puts children with a chronic lung condition caused by premature birth at risk for serious respiratory infections, according to a study from Johns Hopkins Children's Center published in the October issue of Pediatrics.
