Impact of childhood bullying still evident after 40 years

Science News Daily - April 17, 2014 - 8:25pm
The negative social, physical and mental health effects of childhood bullying are still evident nearly 40 years later, according to new research. The study is the first to look at the effects of bullying beyond early adulthood. Just over a quarter of children in the study (28%) had been bullied occasionally, and 15% bullied frequently -- similar to rates in the UK today. Individuals who were bullied in childhood were more likely to have poorer physical and psychological health and cognitive functioning at age 50. Individuals who were frequently bullied in childhood were at an increased risk of depression, anxiety disorders, and suicidal thoughts.

Recalculating costs of combination vaccines

Science News Daily - April 17, 2014 - 6:20pm
One of the most popular vaccine brands for children may not be the most cost-effective choice. And doctors may be overlooking some cost factors when choosing vaccines, driving the market toward what is actually a more expensive option, according to a new study. The researchers encourage physicians and advisory boards to take all factors into account when determining how to administer the best combination of vaccines for the lowest cost.

Multitarget TB drug could treat other diseases, evade resistance

Science News Daily - April 17, 2014 - 6:20pm
A drug under clinical trials to treat tuberculosis could be the basis for a class of broad-spectrum drugs that act against various bacteria, fungal infections and parasites, yet evade resistance, according to a study. The team determined the different ways the drug SQ109 attacks the tuberculosis bacterium, how the drug can be tweaked to target other pathogens from yeast to malaria -- and how targeting multiple pathways reduces the probability of pathogens becoming resistant.

How the immune system protects children from malaria

Science News Daily - April 17, 2014 - 6:17pm
Children who live in regions of the world where malaria is common can mount an immune response to infection with malaria parasites that may enable them to avoid repeated bouts of high fever and illness and partially control the growth of malaria parasites in their bloodstream. The findings may help researchers develop future interventions that prevent or mitigate the disease caused by the malaria parasite.

Malaria pathogen's cellular skeleton under super-microscope

Science News Daily - April 17, 2014 - 6:17pm
The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists used high-resolution structural biology methods to investigate the different versions of this protein in the parasite. Their results may in the future contribute to the development of tailor-made drugs against malaria -- a disease that causes more than half a million deaths per year.

Gene variant raises risk for aortic tear, rupture

Science News Daily - April 17, 2014 - 6:17pm
The significance of a genetic variant that substantially increases the risk of a frequently fatal thoracic aortic dissection or full rupture has been confirmed by researchers. Thoracic aortic aneurysms, or bulges in the artery wall, can develop without pain or other symptoms. If they lead to a tear -- dissection -- or full rupture, the patient will often die without immediate treatment. Therefore, better identification of patients at risk for aortic aneurysm and dissection is considered essential.

Our brains are hardwired for language

Science News Daily - April 17, 2014 - 6:16pm
People blog, they don't lbog, and they schmooze, not mshooze. But why is this? Why are human languages so constrained? Can such restrictions unveil the basis of the uniquely human capacity for language? New research shows the brains of individual speakers are sensitive to language universals. Syllables that are frequent across languages are recognized more readily than infrequent syllables. Simply put, this study shows that language universals are hardwired in the human brain.

Building 'smart' cell-based therapies

Science News Daily - April 17, 2014 - 3:42pm
A technology for engineering human cells as therapies has been developed by scientists. The the technology becomes activated only in diseased tissues. It sits on the surface of a cell and can be programmed to sense specific external factors. For example, the engineered cell could detect big, soluble protein molecules that indicate that it's next to a tumor. When the biosensor detects such a factor, it sends a signal into the engineered cell's nucleus to activate a gene expression program, such as the production of tumor-killing proteins or chemicals.

Inhibited children become anxious adults: Examining the causes and effects of early shyness

Science News Daily - April 17, 2014 - 2:59pm
Three little girls sit together in a room, playing with the toys surrounding them. One of the girls -- "Emma" -- has clearly taken charge of the group, and the others happily go along with her. A fourth girl -- "Jane" -- enters the room, hiding her face while clinging to her mother. The first three continue to play, while mom sits Jane down with some toys a few feet away from the group. After mom leaves, however, Jane sits alone against the wall. Emma makes her way over to Jane, inviting her to play with the rest of the group. Jane -- looking trapped -- starts to cry, then stands up and tries desperately to open the door.
