Gene flow from genetically modified crop plants to their wild relatives will have little overall impact on human health or the environment, predicts a team of researchers in a report released today by the Council for Agricultural Science and Technology.

Gene flow -- the movement of genes from one plant population to another -- has always occurred naturally but has drawn particular attention during the past 10 years, as genetically modified crop plants have moved into commercial production.

"Regulatory requirements and market standards that are specific to crops developed using biotechnology have resulted in much closer monitoring of gene flow than has been done in the past," said plant scientist Kent Bradford, a co-author of the report and director of UC Davis' Seed Biotechnology Cen

Researchers at the University of Rochester have developed a shape-memory rubber that may enable applications as diverse as biomedical implants, conformal face-masks, self-sealing sutures, and “smart” labels.

The material, described in the journal Advanced Materials, forms a new class of shape-memory polymers, which are materials that can be stretched to a new shape and will stay in that form until heated, at which time they revert to their initial shape.

Unlike conventional shape-memory polymers, however, the new material is transparent, rubbery, and most importantly, engineers will be able to control the speed at which it returns to its original shape.

Although there have been great improvements in the field of robotics in the last fifty years, much work remains in order to introduce androids into our daily life. Rafael Muñoz Salinas, a researcher from de Department of Computer Science and Artificial Intelligence of the University of Granada, is the author of a doctoral thesis which represents a major improvement in the interaction between robots and human beings.

Harvard-trained evolutionary biologist Aaron Filler, MD, PhD, has posted a 25 minute video titled, "Hominiform Progression", which he says is a revolutionary direct video view into the evolution of movement among the hominiforms: the apes and humans.

Most remarkable, he says, is video evidence that siamang ape babies naturally learn to walk bipedally as their fundamental and innate means of movement. Filler says this provides new evidence that the infants of a shared common ancestor of humans and apes also learned to walk bipedally as their normal means of movement.

Scientists at Imperial College London have overcome two significant obstacles on the road to harnessing stem cells to build patches for damaged hearts.

Presenting the findings at a UK Stem Cell Initiative conference 13 December in Coventry, research leader Professor Sian Harding explained how her group have made significant progress in maturing beating heart cells (cardiomyocytes) derived from embryonic stem cells and in developing the physical scaffolding that would be needed to hold the patch in place in the heart in any future clinical application.

Domestic violence is an inherent problem in Turkey, and healthcare workers are doing little to combat the prevalence of wife beating, according to research published in the online open access journal, BMC Public Health. A survey of medical personnel reveals that a lack of training and a cultural acceptance of domestic violence may prevent victims from obtaining the support they desperately require.

173 medical staff from the emergency department of a Turkish university hospital responded to a questionnaire about domestic violence. 69.0% of the female and 84.7% of the male respondents declared that they agreed or partially agreed to at least one reason to justify physical violence.
