United States consider Russian rocket engine RD-180 to be the best rocket engine on the world, claim RosCosmos officials.
RD-180 is a two-chamber variant of four-chamber kerosene engine RD-170. The engine owes better specific characteristics, than American analogues have, to closed circuit with reburning of exhaust generator gas in main combustion chambers.
Shipwrecks on coral reefs may increase invasion of unwanted species, according to a recent U.S. Geological Survey study. These unwanted species can completely overtake the reef and eliminate all the native coral, dramatically decreasing the diversity of marine organisms on the reef.
Would you be surprised to learn that nine people died last year on the highway you take to work everyday? Or would you be shocked to see that six teenagers died within five miles of your home in fatal car accidents? With the help of the interactive maps on www.saferoadmaps.org developed by University of Minnesota researchers - you can learn those facts and more by simply typing in your address.
Proposals to reign in wallet-draining gasoline prices by curbing speculation in oil markets would likely increase costs at the pump instead of trimming them, a University of Illinois economist says.
A transition to hydrogen vehicles could greatly reduce U.S. oil dependence and carbon dioxide emissions, says a new congressionally mandated report from the National Research Council, but making hydrogen vehicles competitive in the automotive market will not be easy.
As unwelcome as they are, higher gasoline prices do come with a plus side - fewer deaths from car accidents, says a researcher at the University of Alabama at Birmingham (UAB).
Acts of piracy and terrorism at sea are on the rise, but there is little evidence to support concerns from some governments and international organizations that pirates and terrorists are beginning to collude with one another, according to a RAND Corporation study issued today.
Scientists have found that one of the most intriguing phenomena in condensed-matter physics -- known as the quantum Hall effect -- can occur in nature in a way that no one has ever before seen.
I tagged this with every category since I review books in all realms of science.
Though I plan to maintain my Science Shelf archive of book reviews, I will now also publish the reviews on Science Blog.
Engine exhaust fumes are linked to excess deaths from pneumonia across England, suggests research published in the Journal of Epidemiology and Community Health. The annual death toll is comparable to that caused by the London smog in 1952, suggests the author.

Oceangoing sailing rafts plied the waters of the equatorial Pacific long before Europeans arrived in the Americas, and carried tradegoods for thousands of miles all the way from modern-day Chile to western Mexico, according to new findings by MIT researchers in the Department of Materials Science and Engineering.
A growing number of plug-in hybrid electric cars and trucks could require major new power generation resources or none at all— depending on when people recharge their automobiles.
Rather than improving motorist safety, red-light cameras significantly increase crashes and are a ticket to higher auto insurance premiums, researchers at the University of South Florida College of Public Health conclude. The effective remedy to red-light running uses engineering solutions to improve intersection safety.
Now that the primaries have narrowed the number of viable major-party presidential candidates to three, ScienceDebate2008 promises to give each of them an opportunity to address an issue that is not strictly partisan: science and technology policy and what it means for the future of our nation and the world.
