Researchers use theoretical calculation to understand merger process, predicting brief brightness increase and high-speed gas outflow. The study sheds light on quasar activation following super-massive black hole mergers, a phenomenon not yet fully understood.
Researchers are creating a genetic database for ornamental trees by analyzing the DNA of George Washington's trees. The project, led by Virginia Tech and the USDA Forest Service, aims to understand the genetics of specific tree species.
Researchers found that growth hormone therapy stimulated immunity-promoting cells in bone marrow and other organs of aging rats, increasing red and white blood cell production by up to three times. This approach could lead to increased reserve capacity for immune cells in the elderly.
Researchers reveal how mutations in Hox genes allowed aquatic crustaceans to evolve into six-legged insects, answering a key criticism of evolution. The discovery sheds light on the genetic mechanisms behind macroevolutionary change.
A study found that women are more likely to get regular cancer screenings if they have a well-organized primary care system. Women in private HMOs were also more likely to receive regular screenings compared to uninsured or underinsured women.
Researchers at Duke University Medical Center have traced cellular pathways that enhance the action of antifungal drugs used to treat fungal infections in people with compromised immune systems. Combining fluconazole with cyclosporin or FK506 was found to potently kill fungal cells, and the team elucidated the molecular targets involved.
Georgetown University Medical Center's research found that 53% of medical schools lack training in clinical pharmacology and adverse drug reactions for third- and fourth-year students. Most residency programs offer lectures on the topic but have limited reporting of adverse events.
Researchers found diverse bacterial photosynthetic genes in ocean plankton, actively harnessing energy from light, revealing new types of phototrophs. This discovery has significant implications for oceanic food web models and global carbon budget management.
Groundwater contamination with naturally occurring arsenic poses a significant health risk in Bangladesh and West Bengal. The researcher aims to understand why arsenic levels are high in groundwater and how they will change over time and space.
The NIH panel recommends surgically removing tumors over 6cm in size, while those between 4-6cm may be removed based on hormone production. Minimally invasive surgery is suitable for smaller, non-cancerous tumors.
Scientists have identified the PKHD1 gene as the cause of autosomal recessive polycystic kidney disease (ARPKD), a life-threatening genetic disorder. The discovery provides a genetic roadmap for understanding how the disease progresses, paving the way for more accurate diagnoses and treatments.
Researchers suggest scopolamine could prevent many deaths from nerve agent attacks by reversing physostigmine toxicity in the brain and central nervous system. Studies show improved survival rates with scopolamine compared to atropine, a standard treatment for nerve agent poisoning.
A new study found that caregivers with higher perceived stress levels had infants who experienced more wheezing episodes during the first 14 months of life. Additionally, exposure to German cockroach allergen was associated with increased risk of asthma attacks in susceptible children. Researchers also developed a molecular model of th...
Researchers at the University of Melbourne have developed a potential allergy vaccine using a modified rye grass protein that reduces allergenic response while boosting immune system. The vaccine, delivered in its pure form, may significantly reduce risk of anaphylactic shock and increase immunotherapy efficacy.
