Researchers are identifying the gene that causes Alström Syndrome, a recessive genetic disorder causing blindness, hearing loss, and other conditions. By studying DNA samples from living individuals and their families, they hope to find the gene's location and develop an animal model for the disease.
Researchers found that combining low doses of angiostatin with standard radiation therapy improves response rates without increasing toxicity. The combination causes significant growth inhibition in animal models, even in mice with large tumors.
Scientists have sequenced the complete genome of Treponema pallidum, the syphilis bacterium, providing critical information for developing diagnostic tests, treatments, and vaccines. The genetic blueprint reveals targets for new antibiotics and surface proteins that could stimulate an immune response in experimental vaccines.
Researchers at NASA have developed innovative methods to study molten metals in space, including electrodes and magnets to measure fluid flows and dendrite growth. These techniques will help improve manufacturing processes on Earth by understanding subtle phenomena affected by gravity.
A meta-analysis of 19 drug studies involving 2,318 patients suggests that three-quarters of the beneficial effect of anti-depressant medications can be attributed to the placebo effect. The remaining 25 percent may be due to side effects of the medication.
Researchers aim to prove robotic planes can operate autonomously over the Atlantic Ocean, improving weather forecasting. The autonomous aircraft will gather meteorological data for improved forecast accuracy and potentially detect severe weather.
A team of Cornell University researchers discovered that beetle pupae can create hundreds of deterrent compounds using combinatorial chemistry. The pupae secrete these complex chemicals through microscopic body hairs, thwarting most predators and ensuring their survival in the field.
Researchers at Purdue are testing the effectiveness of golf courses in filtering surface water and studying urban environmental issues. The course is also being used to investigate various creeping bentgrass cultivars and methods to control annual bluegrass, with goals including reducing transplant shock in newly planted trees.
A new study found that narcissists are more likely to become aggressive when they receive negative feedback, but not when they receive praise. The researchers suggest that this is because narcissists are emotionally invested in establishing their superiority and view criticism as a personal threat.
A new study analyzing hate crime data from New York City from 1987 to 1995 found no statistical link between economic fluctuations and rates of hate crimes. The researchers suggest two reasons for this lack of correlation: the decay of aggressive impulses over time, and the role of political leaders in framing economic grievances.
