When it burns, DU forms a uranium-oxide smoke that is easily inhaled and that settles on the ground miles from the point of use. Once inhaled or ingested, depleted-uranium smoke can do a great deal of damage to the human body because of its radioactivity. See How Nuclear Radiation Works...
Fire is hot because thermal energy (heat) is released when chemical bonds are broken and formed during acombustionreaction. Combustion turns fuel and oxygen into carbon dioxide and water.Energy isrequired to start the reaction, breaking bonds in the fuel and between oxygenatoms, but much more en...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic origins of which have been investigated for many...
CA over four days in late July. As a venture investor looking at evaluating and investing in a wide range of advanced nuclear ventures, I was invited to participate and/or sponsor the event. While I wasn’t initially convinced that cold fusion was...
The heat is transferred to a "transfer fluid" (either antifreeze or potable water) contained in small pipes in the plate. Concentrated solar power Concentrated solar power (CSP) works in a similar way to solar hot water in that it transforms sunlight into heat—but it doesn't stop there. ...
A ramjet is a type of air-breathing jet engine that operates on the principle of compressing incoming air without the need for rotating parts. It relies on the high-speed forward motion of the aircraft to compress air, making it suitable for supersonic and hypersonic flight. Ramjets are effi...
Szilard was quite aware of the possibilities of nuclear fission: "These might lead to large-scale production of energy and radioactive elements, unfortunately also perhaps to atomic bombs," he wrote. The physicist played a leading role in producing the world's first atomic chain reaction at the...

If an atom absorbs a photon of light with enough energy — say an ultraviolet photon from a hot star— this absorbed energy can cause an electron to transition to a higher energy level for a short time. This is an unstable situation, however, so the electron drops back down and as it ...
Rain is also often associated with positive experiences and emotions, such as relief from hot weather, the nourishment of crops and the soothing sound of rainfall. These positive associations can make the smell of rain more appealing to humans. Additionally, rain can create a sense of coziness ...
