Black Hole Radiation Blasted Earth During 8th Century
2013-01-21 11:56:25

Lee Rannals for redOrbit.com - Your Universe Online According to a new study, black hole cosmic radiation blasted into the Earth back in the 8th century. Japanese astrophysicist Fusa Miyake discovered last year clues for the strange event located in the rings of ancient cedar trees that dated back to either 774 or 775 AD. Researchers teamed together to determine what had caused the surge in carbon-14 in the rings and found no evidence of a supernova, as they had expected. The...

Measuring The Nuclear Reaction Pathway Of Novae
2013-01-16 05:55:43

April Flowers for redOrbit.com - Your Universe Online A multinational team of scientists has revealed new information about the explosive events known as novae. Novae are dramatic stellar explosions driven by nuclear processes that make previously unseen stars visible for a short time. The team of astrophysicists measured the nuclear structure of the radioactive neon produced through this process in unprecedented detail. The study, led by the University of York, UK, and Universitat...

Scientists Deduce Contents Of Cosmic Mystery Box
2013-01-01 10:16:02

April Flowers for redOrbit.com - Your Universe Online Science teachers in grade school sometimes hand out "mystery boxes," which contain ramps, barriers and a loose marble. Rotating the marble and feeling it hang up or drop, the students begin to deduce the contents of the box. Scientists who are trying to understand why tiny particles rain down from space face a similar dilemma, but on a much grander scale. Their mystery box is a hundred thousand light years across, and the only clues...

Cosmic Radiation May Accelerate Onset Of Alzheimer's
2013-01-01 05:21:42

April Flowers for redOrbit.com - Your Universe Online Space travel is fraught with dangers for astronauts and equipment alike. A new study, led by the University of Rochester Medical Center, reveals that it may be much more dangerous than previously thought. The findings, published in the journal PLOS ONE, show that cosmic radiation — which would bombard astronauts on deep space missions — could accelerate the onset of Alzheimer's disease. "Galactic cosmic radiation poses a...

Nuclear Fallout
2013-04-01 10:26:30

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
