| Narrow focus on physical activity could be ruining kids' playtime Posted: 21 Sep 2014 07:36 PM PDT While public health authorities focus on the physical activity benefits of active play, a new study reveals that for children, playing has no goal -- it is an end in itself, an activity that is fun, done alone or with friends, and it represents "an opportunity to experience excitement or pleasure, but also to combat boredom, sadness, fear, or loneliness."'By focusing on the physical activity aspect of play, authorities put aside several aspects of play that are beneficial to young people's emotional and social health,' says a professor. |
| Fear of failure from a young age affects attitude to learning Posted: 21 Sep 2014 07:35 PM PDT An early established fear of failure at school can influence students' motivation to learn and negatively affect their attitude to learning. The analysis found that irrespective of the goal students adopt those who had developed a fear of failure at an early age were more likely to adopt the goal to validate their ego rather than for their own personal interest and development, and were less likely to use effective learning strategies but more likely to cheat. |
| Immune system of newborn babies stronger than previously thought Posted: 21 Sep 2014 11:51 AM PDT Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense, finds the study. |
| Posted: 21 Sep 2014 11:51 AM PDT Two new technologies could enable novel strategies for combating drug-resistant bacteria, scientists report. Most antibiotics work by interfering with crucial functions such as cell division or protein synthesis. However, some bacteria have evolved to become virtually untreatable with existing drugs. In the new study, researchers target specific genes that allow bacteria to survive antibiotic treatment. The CRISPR genome-editing system presented the perfect strategy to go after those genes, they report. |
| Program predicts placement of chemical tags that control gene activity Posted: 21 Sep 2014 11:50 AM PDT Biochemists have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. By comparing sequences with and without epigenomic modification, they identified DNA motifs associated with the changes. They call this novel analysis pipeline Epigram and have made both the program and the DNA motifs they identified openly available to other scientists. |
| Cancer cells adapt energy needs to spread illness to other organs Posted: 21 Sep 2014 11:49 AM PDT Cancer cells traveling to other sites have different energy needs from their "stay-at-home" siblings, which continue to proliferate at the original tumor site, researchers have discovered. Given that a cancer cell's unyielding ability to metastasize is the primary cause of cancer-related death, understanding how they successfully migrate can be lifesaving. |
| On/off switch for aging cells discovered by scientists Posted: 20 Sep 2014 04:34 AM PDT An on-and-off "switch" has been discovered in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. In our bodies, newly divided cells constantly. However, most human cells cannot divide indefinitely -– with each division, a cellular timekeeper at the ends of chromosomes shortens. When this timekeeper becomes too short, cells can no longer divide, causing organs and tissues to degenerate, as often happens in old age. But there is a way around this countdown, researchers have found. |
| New hepatitis c medication in children to be studied Posted: 20 Sep 2014 04:34 AM PDT After the success of a new drug treatment in adults with hepatitis C infection, a Saint Louis University pediatric researcher is testing the safety and efficacy of the medications in children. The current approach to treat the hepatitis C infection is with interferon shots combined with Ribavirin, a therapy that takes about six to 12 months and also causes many side effects including, flu-like symptoms and depression. |
| Ultrasound enhancement provides clarity to damaged tendons, ligaments Posted: 19 Sep 2014 01:54 PM PDT Ultrasound is a safe, affordable and noninvasive way to see internal structures, including the developing fetus. Ultrasound can also "see" other soft tissue — including tendons, which attach muscles to bone, and ligaments, which attach bone to bone. Now one expert is commercializing an ultrasound method to analyze the condition of soft tissue. |
| New cancer drug target involving lipid chemical messengers Posted: 19 Sep 2014 01:54 PM PDT More than half of human cancers have abnormally upregulated chemical signals related to lipid metabolism, yet how these signals are controlled during tumor formation is not fully understood. Researchers report that TIPE3, a newly described oncogenic protein, promotes cancer by targeting these pathways. |
| Two generation lens: Current state policies fail to support families with young children Posted: 19 Sep 2014 09:22 AM PDT Recent two generation approaches to reducing poverty that help children and their parents are receiving increasing attention. By combining education and training for parents, these programs aim to improve the life opportunities of both. However, according to a new report, while research supports this poverty reduction strategy, state policies fail to provide adequate two generation supports to families with young children. |
