This suggests that 'deblobbing' - the detachment of dense mantle roots beneath the Earth's crust - may be responsible for mountain range formation.
Yale researchers will observe, describe, and explain severe atmospheric turbulence over mountains, focusing on 'gravity waves' that impact the stratosphere. The Terrain-induced Rotors Experiment (T-Rex) project aims to measure properties of whirlwinds formed in mountain ranges and monitor gravity wave behavior.

Researchers have developed DNA-wrapped carbon nanotube sensors that can detect low concentrations of mercury ions in whole blood, opaque solutions, and living mammalian cells. The sensors work by detecting changes in the DNA's shape structure, which is triggered by the presence of target ions.
Researchers found a link between defective PAK enzyme signaling pathways and cognitive decline in Alzheimer's patients. The study suggests therapies targeting the PAK defect could treat cognitive issues in both Alzheimer's and Down syndrome patients.
The Lancet comments on the need for better public education about medical research to alleviate bureaucratic regulation's impact. Patients' trust in data use can increase when they understand rigorous practices and controlled conditions.
Researchers found that consuming three to five servings per day reduces stroke incidence by 11%, while exceeding five servings daily cuts it by 26%. Achieving recommended daily intake goals could greatly reduce stroke-related morbidity and mortality.
The Wisconsin Mentoring Seminar helps graduate researchers develop effective mentorship skills to improve student productivity and retention. The program has been successful in promoting good scientific teaching through its real-time discussions and collaborative efforts.
Researchers discovered that a genetic mutation in Pseudomonas aeruginosa makes it susceptible to destruction by slightly acidified sodium nitrite, a common food preservative. This finding offers new hope for treating cystic fibrosis airway disease.
Researchers found that rain gardens significantly reduced concentrations of nitrates, ammonias, phosphorous and other pollutants reaching storm drains. Design tweaks allowed bacteria in the soil to convert harmful nitrates into nitrogen gas, preventing them from entering groundwater.
A vaccine developed by University of Pittsburgh Medical Center researchers has shown 100% protection against the avian flu virus in an animal study. The vaccine, which contains a live virus, stimulates several lines of immunity and is expected to have greater therapeutic value than traditional vaccines.
Researchers from UC Berkeley found no signature of life in Earth's topography, contrary to previous assumptions. Instead, they suggest that life's influence is more subtle, shaping landforms like rounded hills and meandering rivers, but not creating unique features.
Researchers have identified a new pathway for cancer treatment by targeting the degradation of steroid receptor coactivator 3 (SRC3) through the REG-GAMMA molecule. High levels of SRC3 can lead to tumor growth in breast cancer, but low levels of REG-GAMMA can activate its destruction, potentially halting tumor progression.
