Mysterious and rapid blasts of radiation that sweep over Earth could be the result of starquakes on "dead stars," or neutron stars. This connection could help scientists better understand earthquakes here on our planet. First discovered in 2007, Fast Radio Bursts (FRBs) are invisible to human...
There was an increase in the number of baby boys relative to girls in all of the countries from 1945 to 1975. This was the case in many eastern European countries for several years after 1986.Scientists are putting the first boom down to atmospheric bursts as a result of the atomic bomb ...
Julian Osborne from the University of Leicester, UK, studies gamma-ray bursts, which are emitted by the most energetic explosions in the universe and can last for seconds. He says that the brief pulse seen by Cannon’s team is “pretty amazing”. The pulse was an order of magnitude brighte...
Adaptive radiations may be associated with “early bursts” of species number or morphological diversity, although an increase in the rate of diversification is not a requisite parameter of adaptive radiations1. Classic examples of adaptive radiation include Darwin’s finches3, Hawaiian silverswords4,...
Bursts Theory Gravitational wavesTheoryGravitational wavesThe status and prospects are reviewed for the presently most favored model for the inner engine of cosmological gamma-ray bursts (GRBs): the black hole鈥搕orus model. Support for this model is derived from recent GRB-phenomenology: a ...
COSMIC or galactic noise was discovered by Jansky1 in 1931; but its exact origin has remained uncertain. It is generally supposed to originate from collisions in interstellar matter2; but there are divergencies between existing theory and experimental re

the faster something like this can be done the better. Our technologies revolve around bursts of radiation and sensing those bursts. The picture is meant to illustrate how the technology relates to the mission – whether it is to reduce the time to inspect cars in a parking lot for a terror...
We apply this new physical regime to GRBs, and suggest that the GRB prompt emission spectra whose low-energy photon spectral index has a typical value2–5 −1 could be due to synchrotron radiation in this moderately fast-cooling regime. The radiation mechanism of γ -ray bursts (GMBs), ...
In subject area:Earth and Planetary Sciences A planetary radiation imbalance must exist today, if climate sensitivity is as high (and thus the ocean response time as long) as we estimate and if increasing greenhouse gases are the dominant climate forcing. ...
