Nineteen-year-old U.S. Army Pvt. David Lewis set out from Fort Dix on a 50-mile hike with his unit on Feb. 5, 1976. On that bitter cold day, he collapsed and died. Autopsy specimens unexpectedly tested positive for an H1N1 swine influenza virus.Virus disease surveillance at Fort Dix found another 13 cases among recruits who had been hospitalized for respiratory illness. Additional serum antibody testing revealed that over 200 recruits had been infected but not hospitalized with the novel swine H ...read more
Paleontologists have long debated whether pterosaurs could fly. An analysis of fossils from two separate species of the ancient, winged dinosaur relatives suggest that not only did they fly, but also at least one species likely glided on air currents while another probably flapped its wings, according to a report in the Journal of Vertebrate Paleontology. Researchers determined these different abilities by using CT scans to analyze the fossilized bones. Scanning the humerus of Arambourgiania phi ...read more
Keeping people healthy also means keeping our environment free of pollutants and limiting our exposure to disease-causing microbes. Here we highlight projects that need your help researching and improving human and environmental health. Try one or all of them this month, as we commemorate Alzheimer’s Awareness Month, Pollution Prevention Week (Sept. 15th-21st), World Water Monitoring Day (September 18th) and National Eye Health Week (September 23rd-29th).The eyes have itHelp neuroscientists fi ...read more
Our Sun drives a constant outward flow of plasma, or ionized gas, called the solar wind, which envelops our solar system. Outside of Earth’s protective magnetosphere, the fastest solar wind rushes by at speeds of over 310 miles (500 kilometers) per second. But researchers haven’t been able to figure out how the wind gets enough energy to achieve that speed – until now.Our team of helio physicists published a paper in August 2024 that points to a new source of energy propelling the solar wi ...read more
What if we could see through skin? Scientists have managed to do just that, by mixing a common yellow dye with water and applying it on living mice. They used the technique to peer through the skin on mouse skulls and abdomens, according to a report in Science.The technique has potentially profound implications for medical imaging because it could provide less costly and more effective ways for doctors to see what’s going on in human tissue. The technique, while promising, has not yet been app ...read more
