Ecologists Advise an Increase in Prescribed Grassland Burning to Maintain Ecosystem, Livelihood
Kansas State University

At least 50 percent of the tallgrass prairie in the Flint Hills is burned every three to four years or less frequently and is susceptible to becoming shrubland if fire frequencies are not increased.

Researchers Create First 3-D Mathematical Model of Uterine Contractions
Washington University in St. Louis

Although researchers have been seeking the origins of preterm birth for many years, the causes are still relatively unknown. By studying the electrical activity that causes contractions, researchers at Washington University in St. Louis and their collaborators have developed a multiscale model they believe may aid in predicting preterm birth.

Implanted Neuroprosthesis Improves Walking Ability in Stroke Patient
Wolters Kluwer Health: Lippincott

A surgically implanted neuroprosthesis—programmed to stimulate coordinated activity of hip, knee, and ankle muscles—has led to substantial improvement in walking speed and distance in a patient with limited mobility after a stroke, according to a single-patient study in the American Journal of Physical Medicine & Rehabilitation, the official journal of the Association of Academic Physiatrists. The journal is published by Wolters Kluwer.

Prevention of Genetic Breast Cancer Within Reach
Institute of Molecular Biotechnology

An international team led by researchers at the Austrian Institute of Molecular Biotechnology (IMBA) in Vienna and the University of Maryland School of Medicine in Baltimore discovered that genetically determined breast cancer can be largely prevented by blocking a bone gene. An already approved drug could be quickly available and would then be the first breast cancer prevention drug.

When it comes to claws, right-handed attracts the girls
University of Adelaide

A tiny marine crustacean with a great big claw has shown that not only does size matter, but left or right-handedness (or in this case, left or right-clawedness) is important too.

Heme, a Poisonous Nutrient, Tracked by ‘Green Lantern’ Sensor
Georgia Institute of Technology

The toxin heme is essential to life, but cells must make use of it sparingly and carefully, as poor heme management can lead to Alzheimer's, heart disease and cancer. Researchers at the Georgia Tech have tailored ratiometric sensors to tracks heme's movements in yeast cells for the first known time.

Increased Marrying, and Mating, by Education Level Not Affecting Genetic Make-Up, New Study Finds
New York University

While the latter half of the 20th century showed a widening gap between the more and less educated with respect to marriage and fertility, this trend has not significantly altered the genetic makeup of subsequent generations, a team of researchers has found.

Mouse Study Links Heart Regeneration to Telomere Length
The Rockefeller University Press

Researchers at the Spanish National Center for Cardiovascular Research have discovered that the ends of heart muscle cell chromosomes rapidly erode after birth, limiting the cells’ ability to proliferate and replace damaged heart tissue. The study, “Postnatal telomere dysfunction induces cardiomyocyte cell-cycle arrest through p21 activation,” which will be published online May 30 in The Journal of Cell Biology, suggests potential new interventions to boost the heart’s capacity to repair itself after a heart attack.

A Combined Approach to Treating Metastatic Melanoma
The Rockefeller University Press

Oncologists at the Fred Hutchinson Cancer Research Center have successfully treated a patient with metastatic melanoma by combining two different types of immunotherapy. Cassian Yee and colleagues describe their approach in a paper, “Combined IL-21–primed polyclonal CTL plus CTLA4 blockade controls refractory metastatic melanoma in a patient,” that will be published online May 30 in The Journal of Experimental Medicine.

Weed Stems Ripe for Biofuel
University of Adelaide

A weedy plant found on the roadside in northern Australia has stems ripe for biofuel production. Scientists from the ARC Centre of Excellence in Plant Cell Walls at the University of Adelaide have discovered that a variety of sorghum growing wild in Australia, Arun, has the potential to yield over 10,000 litres of bioethanol per hectare per year.

Identifying How Merkel Cell Polyomavirus Infection Can Cause a Lethal Carcinoma
Perelman School of Medicine at the University of Pennsylvania

A benign virus normally found in the skin can lead to a type of rare, lethal skin cancer. Specifically, infection by the Merkel cell polyomavirus can lead to Merkel cell carcinoma in immune-compromised individuals. Researchers have now identified a type of skin cell as the target of the virus in humans and establishes a new way to investigate this type of oncogenic viral infection and identifies a potential therapeutic agent against this infection.

Organism Responsible for Paralytic Shellfish Poisoning May Affect Fisheries
University of Hawaii at Manoa

The toxic dinoflagellate, Alexandrium fundyense, is a photosynthetic plankton--a microscopic organism floating in the ocean, unable to swim against a current. New research by scientists at the University of Hawai'i at Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST) suggests that ingestion of this dinoflagellate changes the energy balance and reproductive potential of a particular copepod--a small crustacean--in the North Atlantic, which is key food source for young fishes, including many commercially important species.
