New research reveals the Van Allen radiation belts are powerful particle accelerators generating 'killer electrons' that can severely impair satellites. The accelerated electrons have a dramatic effect on human technological systems, including satellite failures and pager service disruptions.
Clinical trials show substantial increase in leukemia-free survival among AML patients treated with Maxamine Therapy. The treatment has been shown to prevent relapse and prolong remission while maintaining a good quality of life.
Researchers created genetically altered mice that exhibit anxiety to study the serotonin system's contribution to anxiety and depression. The model could help develop more refined targets for psychiatric drugs and provide insights into inherited personality disorders.
The US has achieved an all-time high in life expectancy, with a decline in infant mortality rates and teen pregnancy. Despite progress, there are still areas that require further improvement, such as preventable fatal injuries to children and low-birth-weight rates.
Researchers have found a decade-to-decade variability in the depth of summer thawing in certain permafrost regions. By 2050, the active layer over large parts of the Northern Hemisphere could grow thicker due to climate trends.
Researchers study old-growth forests' carbon, water, and energy exchange to understand their role in global climate change. The project aims to provide baseline information on managed ecosystems' impact on global carbon budgets.
Researchers at Columbia University synthesized a derivative of vitamin A that accumulates with age in human eyes and may contribute to macular degeneration. The new synthesis allows for large-scale production of the compound, enabling further experiments to pinpoint its relationship with age-related changes in the retina.
Researchers found that stray maternal cells in umbilical cord blood transplants can engraft and cause graft-versus-host disease symptoms. Treatment involves withdrawing anti-GVH medications, allowing the immune system to reject transient maternal cells.
A clinical trial demonstrates that TPO, administered with G-CSF, boosts stem cell migration and increases the number of patients eligible for autologous stem cell transplantation. The treatment significantly improves re-growth of blood cells after chemotherapy.
The Wistar Institute has been awarded a $20,000 grant to support continued research on TALL-104 cells, which show promise in treating breast cancer. The grant allows the Linda Creed Breast Cancer Foundation to be involved in supporting clinical trials for new treatments and perhaps a cure.
A new experimental compound, CMA-676, demonstrates promising efficacy in treating acute myelogenous leukemia (AML) with an antibody-targeted chemotherapy approach. The treatment shows a remission rate of approximately 40% comparable to standard combination chemotherapy regimens.
The American Physical Society is celebrating its 100th anniversary at a giant meeting in Atlanta, Georgia, from March 20-26, 1999. Over 7,000 physicists and experts will attend the event, which includes keynotes from national political figures and Nobel laureates.
