VIROLOGY: Alzheimer's Risk Factor Also Aids HIV link
The defective lipid carrier apolipoprotein E4 (apoE4) has accumulated a nasty record. Not only are people who have the gene for apoE4 famously predisposed to Alzheimer's disease, but the same risk factor can also worsen several nervous system disorders and promote cardiovascular disease. A study out this week suggests that apoE4 also hastens the death of people infected with HIV, possibly by allowing the virus easy entry into cells.

Honk if you love research: Classic car donation funds cancer studies (2007.08.09)
A Columbus philanthropist donates to Ohio State University's James Cancer Hospital, but not merely in dollars. In August, a unique collection of classic Rolls Royce cars will be auctioned to benefit cancer research.

Right on pitch: How sparrows learn to sing (2007.08.09)
Just like human children, young songbirds need to hear other birds to develop normal vocalizations. Unlike most sparrows, the diminutive grasshopper sparrow uses two different songs, which it memorizes in different ways. Researchers at Ohio State University's Borror Laboratory of Bioacoustics are working to find out how.

People and animals beat the heat at State Fair (2007.08.06)
With the heat index pushing 100 degrees in Columbus, the allure of state fair can also be a risky one. Today alone, the fair's first aid staff has tended to 18 heat-related incidents. Fair participants and visitors are taking extra precautions to keep themselves and their animals safe.

Endangered snake recovers on Lake Erie islands (2007.08.03)
An endangered snake is reclaiming a place on the shores of the Lake Erie islands. A long term study based at Ohio State University's Stone Lab on Lake Erie monitors the snake's numbers and habits, as well as its popularity among the islanders. The researchers' efforts have brought the snake back from the brink of extinction in less than a decade.

Alien fish bully Lake Erie bass (2007.08.02)
With millions of tons of cargo moving among the Great Lakes each season, it's easy for certain small passengers to go unnoticed. One of those was the round goby, a small bug-eyed fish from Eurasia that now swarms the shallow waters of Lake Erie. An ongoing study, based at Ohio State University's Stone Lab on Gibraltar Island, documents how the gobies jockey for a position in the lake's changing ecosystem.

Nanotechnology business comes to Columbus (2007.07.31)
A leading nanotechnology production company is moving to a new facility in Columbus, bringing with it high paying jobs. Texas-based Zyvex Performance Materials, or ZPM, will occupy a former mattress factory on the west side of the Ohio State campus.

Foiled by fractions: Children make more accurate comparisons than adults (2007.07.30)
Learning fractions in elementary school can be pretty traumatic but for all the gnashing of teeth, it turns out children are intuitively better than adults at comparing fractions. This ability comes from a youthful misperception of how numbers are spaced. In one context the misperception turns out to be helpful.

Ancient village escapes urban sprawl (2007.07.25)
What was prime real estate 800 years ago-- still is today. The ancient remains of early agricultural villages are disappearing beneath Ohio's strip malls and housing developments. But for one site, the backhoes are on hold. It's become an outdoor classroom for young archaeologists, and their discoveries reveal new details of the region's ancient cultures.

CSI Columbus: Students learn forensic science (2007.07.24)
A group of high school students is learning all about crime scene investigation during summer forensics camp. Ballistics, fingerprints, cadaver dogs, crime scene photography, and DNA analysis are among the topics in their action-packed schedule. Forensic camp students investigated a staged crime scene at Ohio State University's Waterman Farm on Lane Avenue.

Study measures cancer risk from cardiac CT scans (2007.07.17)
Doctors often order a cardiac CT scan to determine whether patients are at risk for heart attack. While early detection of arterial blockage can save lives, CT scans also expose patients to X-ray radiation. The radiation itself bears some risk of cancer. A new study by doctors at Ohio State University and Mount Sinai Medical Center found a way to measure that risk.

Landscapers embrace sustainable agriculture (2007.07.17)
In the search for secure and sustainable agriculture, some say organic isn't good enough. An alternative landscape design system known as permaculture creates complex local agro-ecosystems. Despite its hippie image in the U.S., scientists say permaculture works, and could be headed for the mainstream. Ohio's first-ever permaculture design certification course took place at a plant sanctuary in Meigs County.

How to grow a tidy nanoturf (2007.07.16)
Self-cleaning windows, no-fog glasses, and stain-free fabrics just came a step closer to reality. Researchers at Ohio State University have discovered a way to coat materials with a transparent layer of very well organized chemical structures that can attract or repel water or oil or conduct electricity.

Shocked tomatoes lose their skins (2007.07.11)

Invention makes jet engines quieter (2007.07.02)
With nearly seven million passengers moving through Port Columbus International airport every year, the jarring sound of airplane noise may be painfully familiar. NASA expects U.S. air traffic to double or triple by 2025, a projection that has engineers working hard to silence the roar. Engineers at Ohio State University have applied for a patent on technology called plasma actuators that could reduce jet noise.

Gene therapy for Parkinson's disease passes first clinical trials (2007.06.21)
