Where infants sleep may affect how long they are breastfed

Science News Daily - February 6, 2016 - 8:56am
A new study indicates that mothers who frequently sleep, or bed-share, with their infants consistently breastfeed for longer than mothers who do not bed-share. Also, pregnant women who expressed a strong motivation to breastfeed were more likely to bed-share frequently once their baby was born. The findings, which come from a study of 678 women in a randomized breastfeeding trial who were recruited at mid-pregnancy, question whether recommendations to avoid bed-sharing due to concerns such as sudden infant death syndrome (SIDS) may impede some women from achieving their breastfeeding goals and could thereby prevent women and their children from experiencing all of the short- and long-term benefits of breastfeeding.

Pioneering discovery leads to potential preventive treatment for sudden cardiac death

Science News Daily - February 5, 2016 - 5:30pm
Roughly 15 years ago, a team of researchers discovered the precise malfunction of a specific protein in the heart that leads to hypertrophic cardiomyopathy, a common culprit in cases of sudden death in young athletes. A team of scientists have now used some of these findings to develop a possible treatment to prevent this inherited disease that can cause the heart to thicken and stop pumping blood effectively, leading to heart failure.

Record Missouri flooding was humanmade calamity, scientist says

Science News Daily - February 5, 2016 - 5:30pm
Why was the New Year's flood in Missouri so bad? Most news reports blamed it on the heavy rain, but a professor of earth and planetary sciences says analysis of the flood data shows much of the damage was due to recent modifications to the river.

'Cannibalism' between stars

Science News Daily - February 5, 2016 - 2:45pm
Stars do not accumulate their final mass steadily, but in a series of violent events manifesting themselves as sharp stellar brightening. Stellar brightening can be caused by fragmentation due to gravitational instabilities in massive gaseous disks surrounding young stars, followed by migration of dense gaseous clumps onto the star, according to a new theory.

Uncovering secrets of elastin's flexibility during assembly

Science News Daily - February 5, 2016 - 2:45pm
Elastin is a crucial building block in our bodies -- its flexibility allows skin to stretch and twist, blood vessels to expand and relax with every heartbeat, and lungs to swell and contract with each breath. But exactly how this protein-based tissue achieves this flexibility remained an unsolved question -- until now. An international team has carried out an analysis that reveals the details of a hierarchical structure of scissor-shaped molecules that gives elastin its remarkable properties.

Protein that switches cancers from inflammation to proliferation identified

Science News Daily - February 5, 2016 - 2:45pm
PAD4 has been observed in cancers but its role was unclear. An Oxford University team have found that PAD4 citrullinates protein E2F-1, which causes it to form a protein complex with BRD4 that drives expression of inflammatory genes.

Chromosomes reconfigure as cell division ends

Science News Daily - February 5, 2016 - 2:45pm
Cells reach a state called senescence when they stop dividing in response to DNA damage. This change can matter greatly to health, but scientists do not yet have a clear picture of how this change impacts the genome. A new study shows that a cell's chromosomes become physically reconfigured at senescence, leading to significant differences in what genes are expressed.
