An Irondale man was taken into custody Wednesday on a federal indictment accusing him of detonating an explosive device outside the Alabama Attorney General’s Office. Kyle Benjamin Douglas Calvert, 26, is charged with malicious use of an explosive and possession of an unregistered destructive device. Charging documents against him say he also placed stickers on state buildings at the same time of the bombing depicting different graphics advocating for various political ideologies. Some included the phrase “Support your local antifa.” Antifa, short for Anti-Fascist, does not describe a particular group, but rather describes individuals who adhere to what they consider...

The Japan Aerospace Exploration Agency (JAXA) has announced that it has successfully demonstrated the operation of a “rotating detonation engine” for the first time in space. The novelty of the technologies in question is that such systems obtain a large amount of thrust by using much less fuel compared to conventional rocket engines, which is quite advantageous for space exploration. On July 27, the Japanese agency launched a pair of futuristic propulsion systems into space to carry out the first tests. They were launched from the Uchinoura Space Center aboard the S-520-31, a single-stage rocket capable of lofting a 220...

What gives here? Conservative talk show host, Mark Levin, makes an excellent observation as well as ask an excellent question. First the Obaminator: "...and the Department of the Interior has announced that they will be sending Swat teamns to the Gulf to inspect all platforms and rigs." Mark Levin: "Swat teams from the Department of the Interior? When I was Deputy Secretary of the Interior Department (during the Reagan administration), I don't remember any Swat teams. Now you heard hims say that the Department of the Interior was going to send Swat teams, I didn't know that they had Swat...

BEIJING — North Korea on Saturday stood by its demand for aid in exchange for shutting down a plutonium-producing reactor, insisting that it would not act until Washington offers concessions.

Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2003 March 14 DEM L71: When Small Stars Explode Credit: J. Hughes, P. Ghavamian and C. Rakowski (Rutgers Univ.) et al., CXC, NASA Explanation: Large, massive stars end their furious lives in spectacular supernova explosions -- but small, low mass stars may encounter a similar fate. In fact, instead of simply cooling off and quietly fading away, some white dwarf stars in binary star systems are thought to...

The United States last week delivered a secret ultimatum to Baghdad, a warning not to use non-conventional weapons on any account in the coming conflict. DEBKA-Net-Weekly’s intelligence sources have learned that a secret high-level emissary entered Iraq under cover to put Baghdad on notice that if non-conventional weapons were wielded by Iraq, the US would not hesitate to level its cities with a nuclear bomb. Washington acted after discovering that Iraq had smuggled two or three nuclear devices at least into the United States for detonation by sleeper cells planted by Iraqi intelligence. The American ultimatum included a demand...
