Researchers predict Alaska's Columbia Glacier will double its rate of retreat and lose nearly 10 miles over the next decade due to increased calving speeds. This is driven by the glacier's terminus being thinner on average and being in deeper water, allowing it to flow faster.
The largest US study on osteoporosis risk factors found that almost half of women over 50 are at risk for the bone disease. The study, led by Dr. Ethel Siris, highlights the need for more women to get tested and treated for osteoporosis, as it can lead to debilitating fractures.
Researchers at Columbia University Irving Medical Center used PET scanning to assess abnormal energy metabolism in the hearts of young patients with fatty acid metabolism disorders. They found that affected children have a diminished capacity to use fatty acids and experience metabolic crises if untreated.
The Louisa Gross Horwitz Prize recognizes the groundbreaking work of Dr. Avram Hershko and Dr. Alexander Varshavsky on the ubiquitin system, which regulates protein balance in cells. Their research has far-reaching implications for understanding cellular processes and diseases like cancer and neurodegenerative disorders.
Durable responses were reported with Bexxar in a clinical trial of 582 patients with relapsed or refractory low-grade NHL. A total of 57% of patients achieved an overall response, while 28% showed a complete response. The average follow-up was 1.3 years, and half of the patients remained in remission for over 14 months.
A new nuclear medicine procedure has received preliminary approval for a clinical trial to diagnose inhalation anthrax in its earliest stages. The technique uses a 99mTc-labeled monoclonal antibody to detect the infection before other diagnostic tests can, enabling early treatment and reducing long-term antibiotic use.
A new study contradicts European clinical trials that excluded stroke patients with early ischemic changes from thrombolytic treatment. After analyzing CT scans, the study found no association between t-PA treatment and increased risk of adverse outcomes in patients with early ischemic changes.
Researchers have found that protease inhibitors used in AIDS treatment can lead to severe cardiovascular problems by accumulating a certain apolipoprotein in liver cells. This accumulation causes the liver cell to release excessive lipoprotein particles into the bloodstream, increasing the risk of heart disease.
Researchers use fractal models to study blue jets and starters, finding they are made of small streamers rather than a solid column. Blue jets propagate slowly from clouds to ionosphere, while starters travel shorter distances with low charge input.
A recent study by Columbia researchers suggests that low doses of radiation can cause widespread mutations in living cells, even if they only affect a small percentage of the population. The findings highlight the importance of considering the 'bystander effect' when assessing radiation exposure risk.
Acceleron Electron Beam has secured a $525,000 grant from the U.S. Department of Energy to develop and commercialize a new non-vacuum electron-beam welding technique that can make welds deeper and narrower than conventional techniques, while increasing production rates and reducing costs.
Professor Christer Bruun of the University of Toronto reveals that ancient Rome's aqueducts were technological marvels that brought clean water to over 1 million people. The Romans separated high-quality water for drinking from water used for flushing, a practice still lacking in many modern cities, including Canada.
A study published in Neuroscience found that the primary role of the startle reflex is to defend the body against strong impact stimuli, such as head blows. The research suggests that humans have the same timing as rats and that the startle response protects against these types of impacts.
Researchers at Columbia University have discovered a treatment for heart failure by correcting a specific cellular defect. Beta blockers prevent the excessive phosphorylation of the ryanodine receptor, allowing it to respond to signals and release calcium ions as needed. This finding offers new hope for treating heart failure.
The HomeChoice Pediatric dialysis system is designed to meet the special needs of young patients with ESRD, offering a safe and flexible option for administering dialysis at home. The system integrates Baxter's PD Link software, enabling remote monitoring and data analysis.
Researchers found that a specific mutation in collagen II affects the interaction with another collagen, leading to cartilage damage and osteoarthritis progression. The study's results provide insight into how mutations in collagen genes contribute to the disease.
Researchers at USC have discovered an increase in BACE enzymes in patients with inclusion-body myositis (IBM), a crippling muscle disease. The findings suggest that cholesterol may play a role in the production of toxic amyloid-ß protein, which could lead to new treatment options for both IBM and Alzheimer's disease.
Astronomers have shed new light on dark matter distribution by tracing it closely to galaxy patterns. They found that dark matter is distributed in a parallel pattern to galaxies and makes up about seven times more mass than ordinary matter.
Scientists took detailed measurements of a pollution plume containing Gobi desert dust and hydrocarbons on both sides of the Pacific, revealing elevated levels of pollutants. The study shows that Asian air pollution can affect air quality in North America, with significant implications for climate change.
A University of Toronto study found that women sexually assaulted by their husbands are more likely to inform police sooner than those sexually abused by boyfriends or acquaintances. The study also found that victims of spousal sexual abuse are more likely to seek treatment and consent to forensic evidence collection.
A Mayo Clinic study investigated the impact of intercessory prayer on patients' medical outcomes, finding no significant difference between the intervention group and control group. The study highlights the importance of addressing spiritual needs in patients, which may facilitate recovery from illness.
Researchers created high-resolution pseudo-images of minerals within basalt and bacterial growth, providing critical information about bacterial metabolism. The technique also creates three-dimensional images, allowing researchers to understand the complex relationships between microbes, minerals, and contaminants.
