Fruit flies drawn to the sweet smell of youth
Aging takes its toll on sex appeal and now an international team of researchers led by Baylor College of Medicine and the University of Michigan find that in fruit flies, at least, it even diminishes the come-hither effect of the chemicals of love -- pheromones.

Study identifies risk factors associated with death of extremely low birth weight infants after NICU
Extremely low birth weight preterm infants have an increased risk of death during the first year of life. Although researchers have extensively studied risk factors that could contribute to the death of preterm infants, limited information is available after infants are released from the NICU. A new study in the Journal of Pediatrics, identifies that African-American background, longer stay in the NICU, and poorer access to health care can increase the risk of death after being discharged from the NICU.

Skin deep
Experiments conducted in a Harvard lab, and described in the Feb. 2 issue of the Journal of Experimental Biology, reveal that, while sharks' sandpaper-like skin does allow the animals to swim faster and more efficiently, the structure of some high-tech swimsuits has no effect when it comes to reducing drag as swimmers move through the water.

Study finds prior preterm delivery indicates subsequent baby will be small even if carried to term
In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that indicate that women who deliver their first baby early are more likely to have a subsequent baby that is small for its gestational age, even when the second pregnancy is carried to term.

Study finds pregnant women with prior cesarean choose the delivery method preferred by their doctor
In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that women who have undergone one prior delivery via cesarean section appear to know little about the risks and benefits associated with undergoing either a second cesarean or trial of labor to attempt a vaginal delivery, and that the preference of their medical provider strongly affects their selection between the two options.

Study finds in utero surgery preferable to surgery
In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that show that, for children with spina bifida, surgery conducted while the fetus is still in utero as opposed to surgery on a newborn is more cost effective due to the costs associated with caring for a child with significant deficits.

Study finds residence in US a risk factor for preterm birth
In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that indicate that duration of stay in the United States is associated with increased risk of preterm birth for Hispanic women.

Study finds some medications may interact with common anti-recurrent preterm birth medication
In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Dallas, Texas, researchers will report findings that indicate that prescription medications may affect the body's ability to metabolize 17-alpha-hydroxyprogesterone caproate, the only FDA approved medication for the prevention of recurrent preterm birth.

Study indicates that induced labor may not lower risk of infection or respiratory problems in newborns
In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, the Pregnancy Meeting, in Dallas, Texas, researchers will report findings that suggest that induction of labor in patients who suffer a rupture of membranes between the 34th and 37th week of gestation (before the onset of labor) does not reduce the risk of infection or respiratory problems in the newborn.

How the zebra got its stripes
Horseflies are unpleasant insects that deliver powerful bites and now it seems that zebras evolved their stripes to avoid attracting the unpleasant pests. Gábor Horváth from Eötvös University, Hungary, and Susanne Åkesson from Lund University, Sweden, show that zebras have the least attractive hides for horseflies.

Amazing skin gives sharks a push
Shark skin has long been known to improve the fish's swimming performance by reducing drag, but now George Lauder and Johannes Oeffner from Harvard University show that in addition, the skin generates thrust, giving the fish an extra boost. The duo also discovered that Speedo's shark skin-inspired Fastskin® FS II fabric surface does not improve swimming speed, although they point out that the figure hugging costumes probably enhance performance in other ways.

New images capture 'stealth merger' of dwarf galaxies
New images of a nearby dwarf galaxy have revealed a dense stream of stars in its outer regions, the remains of an even smaller companion galaxy in the process of merging with its host. The host galaxy, known as NGC 4449, is the smallest primary galaxy in which a stellar stream from an ongoing merger has been identified and studied in detail.

NASA's Chandra finds Milky Way's black hole grazing on asteroids
The giant black hole at the center of the Milky Way may be vaporizing and devouring asteroids, which could explain the frequent flares observed, according to astronomers using data from NASA's Chandra X-ray Observatory.
