Making milk powder seems simple, but it’s not. Creamer must dissolve very quickly in hot coffee, but powder density is critical for infant formula. Dairy scientists from South Dakota State University and chemical engineers from Monash University in Australia are using a single-droplet spray dryer and computation fluid dynamics modeling to determine the drying parameters needed to produce powders with those specific properties.

A newly discovered insect species in prairie cordgrass may explain why increasing seed production has been so difficult, according to South Dakota State University entomologist Paul J. Johnson, a professor in the plant science department. The larvae feed on the developing seed within the plant. This is part of U.S. Department of Agriculture supported research to develop native grasses as a source of biobased transportation fuels.

Roasted vegetables, fruit salads and spinach smoothies can form the basis for a healthy meal and provide a chance to connect as a family. These are insights that 9- and 10-year-olds and their caregivers in South Dakota gained through iCook, a multi-state U.S. Department of Agricultural project to increase culinary skills, family mealtime and physical activity as a means of preventing childhood obesity.

Three Lakota elders are discussing advanced care planning and wills with their peers on Pine Ridge and other South Dakota reservations through an outreach project done in collaboration with a South Dakota State University nurse-researcher. The group developed a Lakota-specific advanced directive brochure and received training to be advance directive coaches. What they’ve done could impact Native American nationwide.

A novel magnetic semiconductor material that is an alloy of cobalt, iron, chromium and aluminum in which part of the aluminum was replaced with silicon may help reduce the power needed to store data in the computer memory. Researchers from the South Dakota State University Physics Materials and Nano-Science Lab are collaborating with the nano-magnetic group at the Nebraska Center for Materials and Nanoscience at the University of Nebraska-Lincoln.

Sparking interest in engineering among Native American youngsters—that’s the goal of a the National Science Foundations’ Pre-Engineering Education Collaborative, but as those involved will tell you, it’s a tough task. Two South Dakota State University researchers decided to find out why college-age Native American students opted for careers in social sciences and nursing rather than engineering.

A low-cost method of removing phosphates from tile drainage water developed at South Dakota State University may help protect lakes and streams. Assistant professor of civil and environmental engineering Guanghui Hua is using steel byproducts to trap phosphates in simulated tile drainage water. He collaborates with assistant professor of agricultural and biosystems engineering and SDSU Extension water management engineer Chris Hay, who has been testing woodchip bioreactors since 2011. Hay envisions installing a steel-containing cartridge as an add-on to nitrate-capturing bioreactors.

Wheat farmers in Kazakhstan lose anywhere from from 10 percent to as much as 50 percent of their wheat crop due to tan spot and Septoria leaf blotch. Research scientist Zagipa Sapakhova of the Institute of Plant Biology and Biotechnology will screen new wheat varieties to improve resistance to these common fungal diseases, thanks to techniques she learned at South Dakota State University.

Patients suffering from aneurysms that extend from their chest into their groin may be helped by a new stent graft, thanks to collaboration between Sanford Health and South Dakota State University. Mechanical engineering associate professor Stephen Gent’s fluid flow modeling “helped validate that the configuration is delivering more well developed blood flow with the design,” according to Sanford Health vascular surgeon Pat Kelly.

The French have spent centuries developing grapes with the unique flavor and character of Burgundy region wines. Cold-climate grape producers are counting on science to help shorten that process. Plant scientists Anne Fennell and Rhoda Burrows from South Dakota State University are part of the research team helping cold-climate grape growers carve a niche in the American wine industry through two U.S Department of Agriculture projects.

A survey of 324 multiunit owners/operators in South Dakota showed that adopting those policies reduced maintenance costs while improving safety. The research was a collaborative project involving nursing researchers at South Dakota State University and the South Dakota Department of Health. State tobacco control officials have developed materials to help more apartment owners institute voluntary smoke-free policies.

Strategic use of locally produced, renewable energy through smart microgrids can reduce power costs and help prevent outages. Assistant professors Wei Sun and Reinaldo Tonkoski of the South Dakota State University Electrical Engineering and Computer Science Department are developing the smart power management technologies that will make it possible for communities and businesses to use locally produced wind and solar energy yet maintain a consistent, reliable power system. The automated system will also facilitate development of a self-healing smart grid that can help prevent power outages.

The same spring rains that lessen producers’ concerns about drought can also lead to soil erosion and nutrient runoff. Keeping soil and fertilizers where they belong—in the field—benefits producers and the environment, according to South Dakota State University plant scientist Sandeep Kumar. He and graduate student Sagar Gautam used computer modeling to determine which farm management methods will produce the best reduction in surface runoff.

Scientists at South Dakota State University analyzed a half-mile slice of Western Antarctica ice core to help determine that climate change begins in the Arctic and moves southward, according to chemistry professor Jihong Cole-Dai of the SDSU Ice Core and Environmental Chemistry Lab. Since 2006, the SDSU research team have been part of a National Science Foundation project to uncover the secrets within the 2-mile long Western Antarctica Ice Sheet Divide ice core.

A compound and an enzyme that occur naturally in cruciferous vegetables—cauliflower, cabbage, broccoli and Brussels sprouts—may help prevent recurrence and spread of some cancers, according to associate professor Moul Dey of the South Dakota State University Department of Health and Nutritional Sciences. When Dey and her team treated human cervical cancer stem cells with phenethyl isothiocyanate (PEITC) in a Petri dish, about 75 percent died within 24 hours using a 20-micromolar concentration of the compound.

The new strain of flu that affected more than 1,000 dogs in Chicago has not yet spread to South Dakota, but South Dakota State University veterinarians advise owners to be vigilant. To test for the virus, veterinarians will swab the animal's nose and throat and send the samples to the Animal Disease Research and Diagnostic Laboratory at SDSU, which typically processes them the same day they are received.

Figuring out what’s happening at a cellular and molecular level may help scientists develop ways to treat or prevent age-related, neurogenerative diseases, such as Alzheimer’s and Parkinson’s. Through National Institutes of Health funding, pharmacy professor Xiangming Guan and his team at South Dakota State University, Guan and his team developed the first imaging reagent that can determine thiol levels in intact living cells. Now they are working on reagents that can selectively show thiol density in subcellular structures, specifically the nucleus and mitochondria. Guan hopes to develop a nontoxic reagent safe enough to be used for diagnostic imaging, like an MRI.
