Fall 2011

Babies who are breastfed are 60 to 70 percent less likely to die of sudden infant death syndrome, or SIDS, according to a new analysis of past studies led by Dr. Fern Hauck, a U.Va. professor. According to the National Institutes of Health, SIDS kills about 2,500 infants in the U.S. each year.As the gap between rich and poor grows, the poor grow less happy and believe less in fairness and trustworthiness, according to a study led by U.Va. psychologist Shigehiro Oishi. Analyzing data from 48,000 people who responded to the General Social Survey between 1972 and 2008, his team…

What’s in the Water?0

New website shows levels of pharmaceuticals in Virginia wastewater

Fall 2011

Want to know what prescription and generic drugs are in your local wastewater? Now Virginia residents can check using a new website created by U.Va. engineering professors Lisa Colosi and James Smith, with graduate student Karl Ottmar (Engr ‘98, ‘10). Wastewater is treated before it’s released into the environment, and Colosi points out that even before the treatment process, there are only small quantities of medications in the water. “While most scientists agree that the presence of pharmaceuticals in the water supply is undesirable,” she says, “the concentrations of these drugs are very low and it is currently unknown what…

Tick bites likely cause allergy to red meat

Fall 2011

Ticks are icky. They spread Lyme disease. And now it appears they might interfere with your ability to enjoy a hamburger. A team headed by Dr. Thomas Platts-Mills, U.Va. professor and former president of the American Academy of Allergy, Asthma and Immunology, recently published findings that suggest that tick bites may cause allergic reactions to red meat. Dr. Platts-Mills says that tick saliva may trigger the human immune system to produce antibodies to a carbohydrate called alpha-gal, which is found in red meat. Dr. Scott Commins, an assistant professor of medicine at U.Va. and lead author of the study, explains…

State-funded preschool programs improve performance of young students

Fall 2011

Do early education programs for at-risk students work? A new study is the first to analyze Virginia’s program statistically, and the results are positive.Curry School of Education professors Francis Huang and Marcia Invernizzi led research that evaluated more than 60,000 students at 1,000 public schools across Virginia. Students were evaluated from the beginning of kindergarten until the end of first grade. About 11,000 had attended a Virginia Preschool Initiative-funded preschool. A majority of the 11,000 children had been identified as at-risk to qualify for the preschool program; they lived in poverty or were homeless, had health or developmental problems or…

Printing Awesomeness0

Class builds replica of jet engine with a 3D printer

Fall 2011

The jet engine was a technological wonder of the 20th century. In the 21st, college students can make one with a printer. This spring, engineering professor David Sheffler’s class built a one-quarter-size replica of a Rolls-Royce jet engine with a 3D printer that fabricated parts from plastic. The printer created parts accurate to 100th of an inch, nearly the level of precision necessary for a real jet engine. A full-size Rolls-Royce AE3007 turbofan jet engine costs approximately two million dollars. The replica? Only $1,500 for plastic and another $300 for metal bearings, nuts and bolts.Of course, the engine won’t be…
