A New Genus and Species of Mammal Discovered in Eastern Brazil
Journal of Mammalogy – A new genus and species of Sigmodontinae, one of the most diverse groups of mammals on the planet, was recently discovered inhabiting Sempre Vivas National Park, located in Minas Gerais, Brazil. This rodent, so far found only in this Park, has been linked to the tribe Phyllotini, and its discovery suggests an expanded diversification of the tribe and an ancient event of diversification in eastern Brazil.

Bioenergy crops have potential as renewable fuel source—and as invasive species
Invasive Plant Science and Management — Cultivation of large grasses for bioenergy production is gaining interest as a renewable fuel source. A sterile hybrid, giant miscanthus, is a promising bioenergy crop that, unfortunately, carries a high establishment cost for growers. A new seed-bearing line may have economic benefits, but it also bears consequences as an invasive species if it escapes cultivation.

Dual anesthetics preferred by most U.S. dentist anesthesiologists
Dentist anesthesiologists may use either general or local anesthesia to ensure that a child remains calm during an operation and feel as little pain afterward, but some choose to use both with children, despite conflicting research on the combined approach. The current issue of the journal Anesthesia Progress reports on a survey given to members of the American Society of Dentist Anesthesiologists (ASDA) asking about anesthesia choices for young patients and reasons behind those choices.

Study finds that shorter waiting time between dental procedures is adequate
Journal of Oral Implantology – Two surgeries are frequently required for tooth replacement with dental implants; however, clinicians must allow for adequate healing time between the procedures. Most patients want to minimize the overall recovery time and thus desire the surgeries be done close together. A study in the Journal of Oral Implantology looks specifically at healing times between the two dental procedures involving tooth replacement.

Malaria: The Constant Epidemic
The Journal of Parasitology – Malaria has been around for millennia, and there are written references to it from early societies in China, India, Mesopotamia, Egypt, and Greece. Each year an estimated 500 million people are infected worldwide, making malaria a major public health concern. Some countries still experience malaria epidemics, which can also result in significant economic losses. Malaria is typically transmitted to humans by mosquitoes that are infected with the protozoan parasite of the Plasmodium species. Much research has been conducted to learn more about the parasites so they can be controlled more effectively or even eradicated; however, there is still more to learn.

Absence or presence of a known indicator can both lead to disease diagnosis
Pediatric and Developmental Pathology – Clinicians are still seeking the most reliable method for evaluation of Hirschsprung disease. One useful indicator is the absence of calretinin-immunoreactive mucosal innervation, part of the process of establishing nerve cells in the colon. However, this method can also pose the risk of a misleading diagnosis, particularly in the very short-segment Hirschsprung disease variant (VS-HD).

The Disappearance of the Kingsnake in the Southeastern United States
Herpetologica – The ecosystems that shape our planet are a delicate balance of water, mineral, plant, and animal life, and a large part of what maintains the natural order is the predator–prey relationship. Unfortunately, when we see a shift begin to occur, and a particular species population starts to thin, it can be nearly impossible to predict how an ecosystem will react to that change, especially if another species becomes abundant.

Preferred javelina habitats affected by climate shifts and controlled burns
Journal of Mammology – Javelinas, medium-sized mammals also known as collared peccaries that resemble pigs in appearance, have been spreading north in New Mexico. Scientists know little about the links between the mammals and their habitat, but they speculate that javelinas may change their behavior to cope with changes in climate.

Cleft Lip and Palate: How Adulthood Surgeries Can Be Avoided
