A study by the University of Pennsylvania School of Medicine found that postmortem sperm procurement requests are increasing, with over half made between 1994 and 1995. Most requests were from wives seeking to create children for their deceased husbands.
A new study shows that giving the drug for a longer period can significantly improve recovery over the standard treatment. About 60% of patients treated with 48-hour methylprednisolone starting at three to eight hours recovered a substantial degree of independence.
The new method allows engineers to visualize how changes in their designs will affect design requirements. Graph morphing enables designers to see the trade-offs between different design variables, making it easier to understand relationships between subsystems.
The ACIS camera will record the energy of each X-ray detected from high-energy objects as unique charge, converting it into a signal to detect different elements. It has very high angular resolution and spectral resolution, allowing scientists to see individual stars for the first time in crowded regions.
Scientists at UB and IBM have reported the first irrefutable proof that d-wave theory is responsible for high-temperature superconductivity in a thallium thin film. This finding builds on earlier work and provides conclusive evidence for proponents of the d-wave theory.
A recent study found that potassium supplements decreased blood pressure by significant amounts, particularly in those with hypertension or high salt intake. The researchers combined data from over 30 studies and enrolled more than 2500 persons, concluding that potassium can reduce blood pressure.
The University of Washington School of Pharmacy has developed a systematic approach to understanding drug interactions by focusing on the four or five enzymes that metabolize most drugs. This research is producing an understanding of the potential for adverse effects among thousands of drug combinations.
A Carnegie Mellon robot, 'Nomad', will traverse 125 miles in the Atacama Desert, exploring navigation, geology and remote operations. The robot can be teleoperated by science center visitors, offering real-time data and visualization.
The Hayward Fault's southern end has moved at double the rate of its northern portion, causing rocks to be 'piled up' on one side and stretched on the other. This increased strain suggests a magnitude 6 earthquake could occur in the near future.
The University of Cincinnati engineers have created a unique high-performance concrete (HPC) mix that significantly strengthens conventional concrete. Tests show the HPC can last up to 80 years without major maintenance due to its denser material and resistance to freeze-thaw cycles.
Researchers analyzed seismic data to determine cause of 1993 event in Australian outback. An iron meteorite over 3 meters in diameter is suggested as possible cause.
