The NASA Marshall Space Flight Center has awarded a $136.9 million contract option to Computer Sciences Corporation (CSC) to provide information services from May 2000 to April 2001. This brings the total value of the contract to approximately $1.05 billion if all options are exercised.
A study by Emory University neurologists found that pallidotomy surgery significantly improves motor function in patients with Parkinson's disease, with persistent benefits extending to both sides of the body. The long-term effectiveness of this treatment has been confirmed through a 36-month follow-up.
Researchers found that people exposed to pesticides were approximately two times more likely to develop Parkinson's disease than those not exposed. In-home exposure to insecticides carried the highest risk of developing the disease.
Scientists have pinpointed the first gene in fruit fly Drosophila that is a target of an alternate control molecule, TRF1. This discovery opens up new avenues for understanding how gene expression is regulated, with potential implications for complex organisms like humans.
Researchers discovered two molecular switches, Jnk1 and Jnk2, that stimulate programmed cell death in response to UV radiation. Disrupting these genes protects cells from lethal doses of UV light, providing a promising new therapy for diseases such as strokes and heart attacks.
The Prosorba® Column is a device that removes harmful antibodies and immune complexes from the blood of patients with rheumatoid arthritis. Patient trials are expected to evaluate its effectiveness and safety in treating this chronic inflammatory condition affecting over 250,000 Canadians.
Researchers found that hamsters use day length information to anticipate winter, and this memory is retained for a season. The study suggests that the hamsters' brain processes seasonal changes in daylight to adjust reproductive cycles.
War has a devastating impact on children's mental health, leading to increased anxiety and depression. The study highlights the need for further research into the long-term effects of conflict on young minds.
A new UC Berkeley study reveals that diverse ecosystems are not immune to invasion by alien species. In a series of experiments, researchers found that high diversity actually increases the likelihood of invader establishment in larger ecosystems.
The METHRO II study found that H 376/95 was effective in preventing venous thrombo-embolism in patients undergoing total hip or total knee replacement surgery. The incidence of venous thrombo-embolism was significantly lower with the highest dosage of H 376/95 compared to dalteparin.
Researchers at UCSF have discovered a region in the telomerase enzyme that could be targeted to kill cancer cells and regenerate damaged cells. The discovery provides new insights into the mechanism of telomerase and its potential as a therapeutic target, as well as its role in regulating cell life span.
