Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began. The discovery underscores the importance of carbon in Earth's climate today, said Matthew Saltzman, associate professor of earth sciences at Ohio State...

The inflammatory response following a spinal cord injury appears to be set up to cause extra tissue damage instead of promoting healing, new research suggests. Scientists analyzing this inflammatory response in mice discovered that the types of cells recruited to the site of the injury are dominated within a week by those that promote inflammation. When chronic, inflammation can prevent healing, and these inflammatory cells are believed to remain at the injury site indefinitely. Meanwhile,...

Too much light at night can lead to symptoms of depression, according to a new study in mice. Researchers found that mice housed in a lighted room 24 hours a day exhibited more depressive symptoms than did similar mice that had a normal light-dark cycle. However, mice that lived in constant light, but could escape into a dark, opaque tube when they wanted showed less evidence of depressive symptoms than did mice that had 24-hour light, but only a clear tube in their housing. "The ability to...

Scientists have countered findings of previous clinical trials by showing that giving supplemental oxygen to animals during a stroke can reduce damage to brain tissue surrounding the clot. The timing of the delivery of 100 percent oxygen "“ either by mask or in a hyperbaric chamber "“ is critical to achieving the benefit, however. "The use of supplemental oxygen after blood flow is restored in the brain appears to actually cause harm by unleashing free radicals," said Savita...

In the quest for smaller, faster computer chips, researchers are increasingly turning to quantum mechanics -- the exotic physics of the small. The problem: the manufacturing techniques required to make quantum devices have been equally exotic. That is, until now. Researchers at Ohio State University have discovered a way to make quantum devices using technology common to the chip-making industry today. This work might one day enable faster, low-power computer chips. It could also lead to...

Americans think locally when they consider whether the loss of U.S. troops overseas warrants troop withdrawals, a new nationwide study suggests. Researchers found that people were more likely to support withdrawing U.S. troops from Iraq if one or more soldiers from their home state were killed there within the past two to three weeks. That was true regardless of how many soldiers from other parts of the country had been killed recently, or how many total national casualties had occurred. "If...

Animals shelter officials housing lost pets that had been implanted with a microchip were able to find the owners in almost three out of four cases in a recently published national study. According to the research, the return-to-owner rate for cats was 20 times higher and for dogs 2 ½ times higher for microchipped pets than were the rates of return for all stray cats and dogs that had entered the shelters. "This is the first time there has been good data about the success...

Women abused by intimate partners suffer higher rates of a wide variety of doctor-diagnosed medical maladies compared to women who were never abused, according to a new study of more than 3,000 women. Many of these health problems are not commonly understood as being associated with violence, such as abdominal pain, chest pain, headaches, acid reflux, urinary tract infections, and menstrual disorders. "Roughly half of the diagnoses we examined were more common in abused women than in other...

Small bits of metal may play a new role in solar power. Researchers at Ohio State University are experimenting with polymer semiconductors that absorb the sun's energy and generate electricity. The goal: lighter, cheaper, and more-flexible solar cells. They have now discovered that adding tiny bits of silver to the plastic boosts the materials' electrical current generation. Paul Berger, professor of electrical and computer engineering and professor of physics at Ohio State, led the team that...

Sitting up straight in your chair isn't just good for your posture "“ it also gives you more confidence in your own thoughts, according to a new study. Researchers found that people who were told to sit up straight were more likely to believe thoughts they wrote down while in that posture concerning whether they were qualified for a job. On the other hand, those who were slumped over their desks were less likely to accept these written-down feelings about their own qualifications. The...
