Step closer to muscle regeneration Posted: 11 Dec 2013 06:39 AM PST Muscle cell therapy to treat some degenerative diseases, including Muscular Dystrophy, could be a more realistic clinical possibility, now that scientists have found a way to isolate muscle cells from embryonic tissue.

Education: Learning with 'stronger peers' yields no boost Posted: 11 Dec 2013 06:39 AM PST A new study contradicts the popular theory that students perform better when surrounded by higher achieving classmates.

Key role of protein in segregation of genetic material during cell division Posted: 11 Dec 2013 06:39 AM PST Researchers have reported the regulator mechanisms of mitosis, a key stage of the cell-cycle for the correct transmission of genetic information from parents to sons.

Novel cancer cell DNA damage repair mechanism unveiled Posted: 11 Dec 2013 06:38 AM PST Cancer cells have an exceptional ability to repair damage to their DNA caused during uncontrolled cell division. Scientists have now unveiled a novel piece of the puzzle of cancer cell DNA repair mechanisms that explain the mechanistic changes in the genetic code of cancer cells.

Different food fish can cause different allergies Posted: 11 Dec 2013 06:37 AM PST Different fish can cause different allergies when eaten. Research into protein provides new insight into these fish allergies.

HIV causes structural heart disease, study concludes Posted: 11 Dec 2013 04:05 AM PST The findings of a study support the introduction of cardiovascular screening in all HIV patients, particularly those with a positive blood viral load.

New test facilitates diagnosis of autism in adults Posted: 11 Dec 2013 04:02 AM PST Researchers have developed a new screening tool to facilitate the diagnosis of Autism Spectrum Disorder in adults. The test is unique in that researchers have, as part of their evaluation, compared the group diagnosed with Autism Spectrum Disorder with psychiatric patients.

Are overweight children less able to handle advertising? Posted: 11 Dec 2013 04:02 AM PST Weight, body shape perception, self-esteem and dietary habits all contribute to how children handle food advertising. A new study suggests that overweight children, in particular, could benefit from special training, in order to increase their media skills in relation to the exposure to advertising.
