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.

Study Seeks to Reduce Effects of the South’s Most Costly Weed
Weed Science—Controlling Palmer amaranth costs Georgia cotton growers more than $110 million each year, making this the most economically destructive weed in the southeastern United States. Many populations of Palmer amaranth have evolved resistance to glyphosate and other herbicides over the last decade, and additional control methods for this weed are now being evaluated.

Human and Animal Interaction Identified in the Viking Age
Journal of Parasitology – Since 2001, ancient DNA has been used in paleoparasitological studies to identify eggs found in soil samples from prehistoric periods, because identification cannot be done by morphological study alone. The species of human parasites living during these periods, provide scientists with a better understanding of how Paleolithic societies might have been organized, with regard to human presence, animal domestication, hunting, and gathering.

Interviews reveal life experiences, needs of older people with clefts
The Cleft Palate–Craniofacial Journal – A child with a cleft lip or palate catches the eye of both parents and researchers, who easily focus on the physical and psychosocial effects of a cleft during the early years of life. Comparatively little attention is paid to adults who have been living with a cleft for decades.

Bone regeneration through tissue engineering offers new prospects for oral procedures
Journal of Oral Implantology—Regeneration of bone tissue could greatly benefit people with jawbone deficiencies due to tooth loss, infection, or trauma. While an ideal method of bone tissue engineering is not yet available, research with a collagen-hydroxyapatite-Mesenchymal stem cell composite is showing promise.

Gene study finds link with implications for melanoma therapy
Pediatric and Developmental Pathology – An odd-looking or changing mole or birthmark is always worrisome, particularly on a child. While most are benign, “cancer” jumps into every parent’s mind. Gene studies and potential related therapies are just one front in the wide-ranging battle against melanoma.

Vitamin D Deficiency Linked to Pediatric Deaths
Pediatric and Developmental Pathology– Vitamin D is essential for absorbing calcium and for calcium metabolism. In newborns and young children, Vitamin D deficiency, especially when accompanied by hypocalcemia can cause unexpected death. Studies suggest that there is also a correlation between Vitamin D deficiency, early childhood asthma, and children with multiple infections. Finally, lack of vitamin D may cause bone fractures. Receiving the right levels of calcium begins in the womb and continues through birth and development, so the mother’s intake is as important as the child’s after birth.

Craniofacial birth defect has little effect on parental stress
The Cleft Palate–Craniofacial Journal – Becoming a new parent is always stressful—it changes an adult’s entire world. People assume that the stress is heightened when a baby is not perfectly normal, but researchers wonder if that is really the case.

DNA analysis reveals origin and dispersal of the microorganism Cyanidiophyceae in Iceland
Phycologia—DNA research provides evidence that some species of Icelandic algae may have originated in northeastern Asia. Species in a study in the current issue of Phycologia have been found coexisting only in Iceland, New Zealand, Russia, and Japan.

The First Phylogeographic Analysis of a Dry Region in Northern South America
Journal of Mammalogy – Unlike what flourishes in the rainforests of South America, the plant and animal life in the seasonally dryer climates have received very little attention. It has taken until 2014 for the first study to be published regarding the history of the geographic analysis of flightless vertebrate in the dry climates of northern South America.
