Pregnancy problems surface after earthquake
By measuring birth outcomes for infants born before, during, and after the 2005 earthquake in Tarapaca, as well as those born within and outside the affected regions, and controlling for maternal and county-level characteristics, the study isolated the effect of exposure to the catastrophe from other determinants of birthweight. Above, a street in Tarapaca following [...]

Fighting proteins guide embryo development
Researchers used confocal microscopy to visualize the spatial distribution of two proteins that compete for the MAPK enzyme in early fruit fly embryos. Areas where levels of a protein important for head development were high (red, brighter color indicating more protein) there was less enzyme available to act upon a different protein (green) that is [...]

Jumpy proteins repair DNA ‘potholes’
DNA is suspended as tightropes on beads to permit direct single molecule imaging of the lesion search process during repair. Bennett Van Houten, senior author of the study, says the repair process is “akin to spotting potholes on every street all over the country and getting them fixed before the next rush hour.” (Credit: Neil [...]

Using math to formulate sex offender laws
A mathematical model is designed to help communities and policymakers focus on the spatial management of sex offenders and not mere punitive measures. “A lot of local policies are knee-jerk reactions,” Tony Grubesic says. “As a result, communities may actually expose themselves to a net-greater risk than in the absence of a law.” (Courtesy: iStockphoto) INDIANA [...]

Knowing their family history helps kids cope
Using a “Do You Know” scale researchers measured knowledge of family history. Teens who knew more stories about their extended family showed “higher levels of emotional well-being, and also higher levels of identity achievement, even when controlling for general level of family functioning,” the researchers report. “There is something powerful about actually knowing these stories.” [...]

Why surprises temporarily blind us
Brain regions that are active when an individual was searching for a target letter are shown in red; those that reacted to a surprise stimulus are shown in blue. The inferior frontal junction, shown in yellow, was involved in both processes and is believed to play a primary role in coordinating the two different types [...]

Audibility maps help tune out office buzz
Above, an audibility map showing the intelligibility that would be experienced by a listener in every part of a room with a lot of echoes. Intelligibility is best (red) near where the person is talking and weakest at the blue area which is close to a noise source. The software can make similar predictions for [...]

Old arteries blocked? Just grow new ones
Coronary arteries can become blocked with plaque, leading to a decrease in the supply of blood and oxygen to the heart. Severe blockage in multiple major vessels require coronary artery bypass graft surgery. “Successfully growing new arteries could provide a biological option for patients facing bypass surgery,” says Michael Simons.

Moms don’t need moola to be successful
“Results showed that those mums who became ‘happier in themselves’ compared to their own rating from two years earlier were also caring for their toddlers in ways which are more beneficial for children’s well-being and development,” says Sarah Stewart-Brown. “What strengthens this finding is that we also found the converse; when mum’s reported that their [...]

Unexplained leukemias traced to mutation
“Now we’re able to point to a distinct type of mutation for half of the remaining leukemias for which we didn’t know the cause and between one-quarter and one-third of leukemias in older patients,” says senior author Craig Thompson.
