Researchers at NASA and the University of Alaska have discovered mysterious bursts of colored light in thunderstorms, known as sprites. These brief, fleeting phenomena contain a great deal of energy, which may be sufficient to drive novel chemical reactions, potentially impacting the Earth's protective ozone layer.
Scientists at Oak Ridge have invented an aluminum-based propellant allowing for varying speed control. This technology enables the use of rubber bullets with reduced lethality, avoiding fatal outcomes at close range.
A new study reveals that the detailed spectral behavior of solar flares falls into just two categories, suggesting a common mechanism for particle acceleration. The finding could provide insight into how particles are accelerated to high energies in solar flares.
Researchers observe highly nonexponential folding times in yeast phosphoglycerate kinase and ubiquitin mutant proteins. Downhill folding theory suggests a protein encounters temporary structures en route to its native state.
Researchers use telescopes and computer simulations to understand gamma-ray burst explosions. They find evidence of shock waves generated by collisions between material flowing out at different velocities, potentially revealing the cause of initial visible light emission.

A low-protein diet boosts thermogenesis, releasing excess energy as heat rather than storing it as fat. This results in reduced body weight gain and increased exercise motivation.
The US Energy Department has established a long-term climate research station on Nauru in the Central Pacific Ocean. The facility will collect data on the sun's energy transmission, absorption, and reflection in the tropics, focusing on cloud effects on heating and cooling the atmosphere.
JASMIN will measure magnetic field direction and strength from space, resolving details of the Sun's magnetism nearly 20 times better than ground-based telescopes. The instrument aims to unravel mysteries of the Sun's corona heating, heat waves and solar flares, with potential implications for Earth's climate.
Scientists estimate a small amount of life could have existed on Mars through chemical reactions over billions of years. They also explore the possibility of life on Europa, estimating lower energy availability than on Mars.
High-temperature superconducting materials have limited performance due to energy loss caused by defects and grain boundaries. A University of Wisconsin-Madison experiment found that designing better conductors with improved current flow is crucial for overcoming this barrier.
Sandia National Laboratories has proposed a design for an accelerator, X-1, that aims to achieve high-yield fusion. If funded, the project is expected to reach initial operating capability by 2007 and high-yield fusion by 2010, providing important data for the nation's stockpile stewardship program.
The Building Design Advisor (BDA) is an advanced decision-making tool that enables architects to design more energy-efficient, economic, and comfortable buildings. With its easy-to-use interface, BDA integrates multiple simulation tools to provide a comprehensive view of building performance.
Researchers at Sandia National Laboratories have created a quantum mechanical transistor that can process information faster and consume less power than current transistors. The device has the potential to be used in high-speed computing, chemical detection, and other applications.
The home features a complex system of sensors and actuators that monitor temperature, light, sound, and motion to anticipate occupants' needs. This AI-powered system adapts to the household's lifestyle, maximizing comfort while minimizing energy waste.
Researchers find preferred shapes and sizes of lead inclusions in aluminum, which affect melting behavior and material properties. The discovery has implications for understanding and engineering the behavior of nanoparticles in various alloys.
The Sandia Z accelerator has quintupled its output from 40 to 210 terawatts, achieving a temperature of 1.5 million degrees, crucial for nuclear fusion. This breakthrough advances basic scientific research and contributes to US defense without physically exploding large-scale devices.
The article argues that deregulation has resulted in lower energy prices for consumers, comparable to those in 1949 when adjusted for inflation. Free markets have also devised solutions to manage price risks through hedging instruments, allowing large consumers to lock in prices and mitigate volatility.
Researchers at the University of Delaware have developed a new theory on how chemical additives alter the growth rate of silicon and silicon-germanium alloys. By understanding this mechanism, they hope to improve the control of electronic properties in films grown from chemical vapors at low temperatures.
Astronomers have discovered a 45-day cycle of radiation surges from V1159 Ori, a cataclysmic variable system. The energy release is due to hydrogen buildup around the white dwarf triggering a massive dump of material, resulting in an enormous energy surge.
The CUBIC observatory aims to learn more about the unknown sources of a diffuse glow of X-rays reaching the Earth. By studying the energy spectrum of these X-rays, scientists hope to gain insights into the makeup of hot gas that emitted them.
Researchers at Rutgers University are developing metalloprotein models to emulate nature's energy conversion process using state-of-the-art equipment. The models have the potential to lead to efficient molecular-based solar-energy systems and possibly molecular-based computers that derive their energy from synthetic metalloproteins.
