Chemists have developed two novel methods to characterize 3-D macroporous hydrogels — materials that hold great promise for developing ‘smart’ responsive materials that can be used for catalysts, chemical detectors, tissue engineering scaffolds and absorbents for carbon capture.
An international paper on folate biomarkers is part of an initiative to provide evidence-based guidance for the global nutrition and public health community. The comprehensive study on folate, an essential B vitamin required for DNA synthesis and normal growth and development, represents a consensus of the top folate scientists globally. A major birth defect affecting the spinal cord — spina bifida, for example — and brain can be prevented by maternal consumption of sufficient folate prior to and during the very early stages of fetal development.
Scientists have synthesized qualitative and quantitative evidence to form a clearer picture of the extent and types of mistreatment that occurs during childbirth in health facilities. Such initiatives are key to developing policies to reduce and ultimately eliminate this inhumane and degrading phenomenon.
The spinal cord engages in its own learning of motor tasks independent of the brain, according to an innovative imaging study. The results of the study may offer new opportunities for rehabilitation after spinal cord injury.
Past research shows men find female faces more attractive at peak fertility. A new study shows an increased redness of women’s face skin at the most fertile point of ovulatory cycle, but just under the threshold for detectability, ruling out skin coloration as a driver of the attractiveness effect.
Forest composition, ground cover and topography are the best predictors of forest fire severity in the Western US, according to physical geographers who also see that the long history of fire exclusion on federal lands leads to uncharacteristically severe burns and potentially changes the dynamics of forests and their recovery.
