Research suggests Tourette's syndrome is not a simple motor disorder, but rather a condition affecting the brain's circuits that control planning and decision making. The study found that individuals with Tourette's can anticipate and adjust to their tics, indicating intentional movement.
The University of Iowa team will use a low-frequency radar to probe beneath the Martian surface and study the planet's ionosphere. The goal is to detect signs of liquid water, which may be responsible for carving the planet's canyons.
Researchers at Penn State have developed a new mobile data access system (MDAS) that enables efficient access to diverse data sources through both wired and wireless connections. The system uses multidatabases to provide integrated access to multiple databases with a single query, reducing traffic jams caused by simultaneous queries.
A gamma-ray burst may have melted primordial dust grains, seeding the formation of meteorites and rocky planets like Earth. The theory suggests that only one Sun-like star in a thousand would be close enough to form chondrules.
Researchers at Harborview Medical Center are exploring a new approach to treat depression by introducing extra copies of the gene for 5-HT1b receptors into serotonin neurons. Preliminary results suggest that this technique may allow for faster and more effective treatment of depression.
A University of Iowa study reveals that high salt concentrations in the airways of people with cystic fibrosis prevent antimicrobial peptides from working effectively. This finding provides new ideas about potential treatments for the disease.
For the first time, researchers have designed a working molecular motor that can convert chemical energy into controlled motion. This breakthrough advances miniaturization technology to the single molecule level, with potential applications in understanding diseases and developing new treatments.
Researchers at Memorial Sloan-Kettering Cancer Center have developed a new drug that targets histone deacetylase, an enzyme that regulates cell growth and division. The drug, called SAHA, has shown promise in treating various types of cancer, including breast, lung, and prostate cancers.
Researchers at Vanderbilt University have developed a groundbreaking treatment for self-injury in people with developmental disabilities. By combining communication training with naltrexone, a medication that blocks the brain's opiate receptors, they were able to significantly reduce or eliminate self-injury in most cases.
Third-year medical students who completed an ethics course showed a deeper understanding of medical issues and made more informed decisions. The course improved their ability to consider patients' capacity for informed choice and evaluated the benefits of physician-assisted suicide, according to lead author Risa P. Hayes.
According to Professor Valerie Randle's research, the imbalance in senior positions is attributed to differing attributes and aspirations of men and women. More women are now aspiring towards senior management positions due to growing schemes like networking and mentoring.
