A new NASA-funded study reveals that human-caused land-use changes significantly contribute to climate change, potentially more so than greenhouse gas emissions. The research proposes a method for comparing different climate change factors, highlighting the importance of land surface changes in redistributing heat and affecting regiona...
Recent research suggests that West Antarctic ice streams are experiencing normal variability, contrary to predictions of imminent shutdown and sea-level rise. The study found that local conditions, such as geothermal heat and frictional forces, drive the slowdown or speeding up of ice streams.
Researchers have developed a semiconductor technology that converts waste heat into electricity with unprecedented efficiency. The new device, called 'thermal diodes,' operates at high temperatures and has the potential to revolutionize power generation and recovery of waste heat from power plants and automobiles.
Researchers found a significant difference in movement on each side of the Eastern California Shear Zone, with one side moving more than the other due to varying heat flow properties. This discovery provides a more accurate method for modeling earthquake data and could be applicable in many places.
Researchers from the University of Pennsylvania discovered that carbon nanotubes can conduct heat exceptionally well, potentially addressing overheating issues in microchips. The discovery could lead to applications in various fields, including electric motors and aircraft components.
University of Illinois researchers have developed a theory that explains how glassy materials behave and predict the speed of molecular motion changes with temperature. The theory, based on thermodynamic measurements of heat capacity, provides a universal form for expressing glass transition phenomena.
Scientists at PPPL have achieved a significant breakthrough in fusion research, producing the highest plasma current ever recorded in a spherical torus device - 1 million amperes. This milestone is crucial for understanding the physics of fusion and potentially leading to more efficient development paths for fusion energy.
Two scientists suggest that satellites' waste heat could be causing distant spacecraft to slow down faster than expected. The heat is emitted in a direction opposite to the Sun, giving the spacecraft a small push towards the Sun and slowing them down.
Urban Heat Island Pilot Project measures city cooling with urban forests. Cities like Sacramento & Salt Lake City use trees to reduce surface heating, improving air quality & mitigating heat stress. The study helps develop planning strategies for cities worldwide.
Researchers are studying the impact of Atlanta's growth on its air quality and temperatures over two decades. Trees have been found to reduce temperatures, with a difference of up to 31 degrees between paved areas and tree-lined spaces. The study aims to provide insights for cities reshaping themselves for comfort and lower heating bills.
The Oak Ridge National Laboratory has developed a new wall testing and rating procedure to determine the thermal performance of entire walls, rather than just insulation. This approach accounts for increased heat leakages in corners, doors, windows, and studs, providing more accurate measurements of building energy performance.
