Setting and achieving goals related to income and education may improve the overall health of Native Americans--that’s the premise behind a new research project, We RISE—raising income, supporting education—targeting young mothers on the Cheyenne River Indian Reservation in north central South Dakota. Health disparities research typically controls for socioeconomic status in analyses, but this study looks changing those socioeconomic variables.
Jumping up a 2-foot waterfall is an impossible task for small fish like minnows and shiners. Such an obstacle can inhibit their ability to feed and spawn upstream. But state and federal wildlife agencies may soon be able to install fish ladders on the downside side of culverts to prevent this from happening.
Soybean roots are under attack from two culprits, a parasitic round worm called the soybean cyst nematode, feeds on the roots, and a fungal disease called sudden death syndrome, which inhibits root growth. Soybean fields affected by both feel the greatest impact on yields. Planting resistant varieties and rotating crops are essential.
When it comes to reducing the number of walleye, anglers take a back seat to Mother Nature. That’s the one of the insights on harvest dynamics emerging from a research project to assess movement, mortality and the impact of anglers on walleye populations along the Missouri River from the Oahe Dam near Pierre, South Dakota, north to the Garrison Dam near Riverdale, North Dakota.
Resistance, stability and flexibility training can improve balance and other functional movements for people diagnosed with multiple sclerosis—and behavior therapy may further improve their quality of life. That’s the premise of a study that builds on previous work suggesting that resistance and flexibility training improved balance and symmetry, which is of particular concern for those experiencing leg weakness.
Plants share their carbohydrates with arbuscular mycorrhizal fungi that colonize their roots and, in exchange, these fungi provide their hosts with nitrogen and phosphorous. By exploiting this relationship, scientists may be able to increase the biomass production of bioenergy crops and the yield of food crops and to reduce the required fertilizer inputs. This could improve the environmental sustainability of agricultural production systems according to professor Heike Bücking of South Dakota State University.
Researchers have found antibodies to the newly discovered influenza D virus in pigs, cattle, horses, goats and sheep, but not poultry.

“Breeding is a numbers game—the more combinations we test, the more likely we are to identify a superior plant,” said winter wheat breeder Sunish Sehgal. He develops more than 500 new genetic combinations each year to increase winter hardiness, yield and disease and drought resistance in South Dakota wheat varieties.
“If you live in flammable countryside, you’ve got to work with fire. You can’t make it go away,” according to professor Mark Cochrane, a wildfire expert and senior scientist at the Geospatial Sciences Center of Excellence. That means moving from the notion that fires are unnatural and toward a managed approach that involves reintegrating fire as a vital landscape process and building communities that are resilient to fire.
Changing crop prices was the No. 1 factor that farmers in the Prairie Pothole region of eastern South Dakota and southeastern North Dakota considered when deciding whether or not to convert grassland to cropland. Of the 1,026 producers who responded to the 2015 Farmland Decision Survey, 40 percent had converted some native or tame grassland to cropland in the last 10 years.

The device could save lives, whether it be diagnosing exposure from an industrial fire or a terrorist attack
“Secure, healthy caregiving is just as important as genetic factors in preventing physical and emotional problems,” according to South Dakota State University nursing professor Marylou Mylant. That’s the premise behind research on strengthening families to fight a dramatic increase in obesity among Native American preschoolers. Less than 25 percent of the preschoolers at the intervention site have normal BMIs.
Using natural soil components to trap pollutants will allow producers to control soil contaminants and reuse draining water while protecting their agricultural crops, according to Mohamed Elsayed, a Fulbright Postdoctoral Scholar at South Dakota State University’s chemistry and biochemistry department. His research seeks to increase the ability of humic acid to adsorb, or trap pollutants, in combination with either of two clay minerals—kaolinite or montmorillonite.
Tumor cells require high levels of glucose to multiply. This, in turn, creates more lactic acid, a byproduct that negatively affects the body’s immune response thereby reducing the effectiveness of drug therapies. Scientists from Sanford Research and South Dakota State University are using a low-glucose diet and specially designed anti-cancer drugs to improve therapeutic outcomes in cancer patients.
As the price of gasoline drops, the number of automobile crashes increases, according to analysis of monthly crash data. from the Minnesota Office of Traffic Safety for 1998 to 2007. However, the time frame within which this occurs varies based on the driver’s age, according to South Dakota State University sociologist Guangqing Chi. He led the multi-institutional team of researchers who analyzed crash data from Minnesota, Mississippi and Alabama in relationship to gasoline prices.
Tillage practices that conserve moisture, plants that use water more efficiently and soil with more organic matter have produced higher yields even in dry conditions, according to soil scientist David Clay, professor of plant science at South Dakota State University. In addition, scientists have a better understanding about how water stress decreases the plants’ ability to take up nutrients and recover from pest injury.
Nurses, doctors, pharmacists and therapists care for the same patient, but often don’t meet until they are practicing health professionals.
