New software program assists pathologists with process of perinatal autopsy
Pediatric and Developmental Pathology – After the death of an infant, a thorough postmortem examination can provide needed answers. Fetal and infant autopsy can yield information about the cause of death and risk of recurrence in future pregnancies. It may also provide closure to grieving parents.

Orofacial Clefts and the Impact on Academics
The Cleft Palate-Craniofacial Journal – One of the most common birth defects in the United States is being born with a cleft lip (1 in 940) or a cleft palate (1 in 1574), referred to as orofacial clefts (OFCs). Children with OFCs have faced challenges in school such as cognition, reading, language, hearing, speech, and developmental and behavioral problems, which leads to poor academic achievement compared with their peers.

Intensity and Duration of Invasive Plants Can Guide Management at Microsite Level
Invasive Plant Science and Management—The detrimental effects of invasive nonnative plants on the ecosystem are well-documented. However, the long-term influences on native plant diversity and abundance at the microsite scale are not as extensively studied. This information can help shape management efforts to support recovery of native plant communities.

Parasites vs. Humans: The Last 50 Years
The Journal of Parasitology – The battle between humanity and parasites is a constant struggle. As parasites grow stronger by developing immunities, new treatments must be created in response. On the frontlines of this struggle are parasitologists, scientists who specialize in studying various parasites (including insects, worms, viruses, and bacteria) and their hosts.

Algae invade amphibian egg masses
Phycologia – The establishment of symbiotic systems requires one organism to live in or on a host. For some North American amphibians, these symbionts are algae and they associate with their aquatic egg masses. Researchers have begun to speculate that these smaller organisms initially invade embryonic host tissues and cells and then transfer to the next generation of hosts.

Smaller anesthesia needle bore fails to reduce pain
Anesthesia Progress – A local anesthetic is often given during dental work to lessen pain, but for many patients the anesthesia injection is as bad or as scary as the experience of dental treatment itself. Dentists are constantly looking for ways to reduce the pain produced by injecting the numbing agent.

Review of whole slide imaging for pediatric specimens advances validation process
Pediatric and Developmental Pathology—Whole slide imaging is an emerging technology that is poised to impact the practice of medicine by extending the virtual reach of pathologists. Classified as a medical device by the U.S. Food and Drug Administration, whole slide imaging must be validated and approved before use in primary diagnosis. The College of American Pathologists has published guidelines for this validation, and a new study applies those guidelines specifically to specimens in the pediatric population.

Foot Webbing Coloration Signifies Visual Signals of Maturation in Frogs
Herpetologica – Color and pattern change upon maturation is not uncommon among numerous animals. These changes tend to signify sexual development within the species and also increased male–male competition in searching for mates. Among frogs, color and pattern changes are quite common. Although vocal signals are normally used as a mode of communication, some frog and toad species use visual cues as well.

Insecticide Treatments in Combination with Herbicides Cause Crop Injury and Yield Loss
Weed Technology—As growers across the southern United States have planted increased corn acreage in recent years, corn-attacking insects have become a widespread problem, including populations of the western corn rootworm that have developed resistance to insecticidal proteins produced by genetically modified Bt corn varieties. A new study published in the journal Weed Technology investigated effects on crop health of combining insecticide and herbicide treatments.
