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.

Updated Weed Management Software Offers 10-Year Impact of Farming Decisions
Weed Technology—A weed management software program, RIM (Ryegrass Integrated Management), allows users to evaluate the impact of today’s weed management choices across a 10-year horizon. First developed in the 1990s, RIM has been upgraded to include more than 40 updated management options and a user friendly interface. Originally designed for cereal crops in Australian dry environments, RIM is now easily adaptable to other broadacre farming situations and other annual weeds, such as encountered in the US. A key feature of RIM is to explore issues such as the economic impact of herbicide resistance, before practices are implemented in the field.

Release Criteria for Biological Weed Control Agents Should Include Benefit and Risk
Invasive Plant Science and Management—Attempts to achieve biological weed control with insects are met with stringent risk assessment in the United States. Before insects are released, their potential to attack economically important or threatened plants is closely evaluated. This assessment focuses on risk and does not adequately address host-range data, especially results from multiple-choice and open-field tests; therefore, it may result in missed opportunities for safe, effective, and natural weed control.

Parasites and people: Feeding off each other
The Journal of Parasitology – Malaria, parasitic worms, Ebola, HIV, even bed bugs—today’s parasites and pathogens get nearly daily media coverage. As a species, humans affect the lives of everything else on our planet, ranging from the tallest trees to these smallest of organisms. In turn, these changes also affect the parasites that infect us and other animals, and it now seems that the parasites are spreading ever more widely, and sometimes rapidly and aggressively, across Earth.

Study Predicts No Farmers and Ranchers under 35 by 2033
Rangelands – When did you last hear a high school senior say “I’m taking over the ranch” or even a 7-year-old announce “I want to be a farmer”? As long-time farmers and ranchers grow older, it’s becoming increasingly difficult to pass on the family farm or find young employees to pick up the reins at large corporate ranches.

Suction of oxygen can reduce risk of surgical fires in dental procedures
Anesthesia Progress—The oxygen-enriched environment of surgical procedures creates the risk of fire. As many as 600 operating room fires occur each year in the United States despite a decline in the use of flammable anesthetics. To ensure the safety of dental surgical procedures, a new study investigated the use of suction to prevent combustion.

Lower Seeding Rates of Soybean Can Be Combined with Pre-Emergence Herbicide
Weed Science—The cost of soybean seed has increased more than 225% since the introduction of glyphosate resistant varieties in 1996. This increase in price has caused growers to reduce the rate of seeding in fields. However, the lower crop seeding rate can lead to a more open canopy for weeds and increased competition with the crop.
