US to Jettison Spy Planes, Satellites Due to Russian, Chinese Missiles - Reports  

Moscow (Sputnik) Feb 22, 2018 The US Air Force is about to abandon expensive surveillance aircrafts and satellites, opting for an information network out of concerns over Russia's and China's increased space capabilities. The United States has decided to ditch a $7 billion surveillance aircraft program in favor of an information network that connects sensors from manned and unmanned aircraft, satellites, ships at sea a

Watch: Not just one but TWO hurricane-force storms swirling in the North Atlantic Ocean  

In recent days, two powerful storms packing hurricane-force winds have spun up in the North Atlantic. You can watch them in the animation above of GOES-16 satellite imagery. It was posted to the awesome GOES-16 Loop of the Day website. The storm closer to North America was so strong that it churned the waters up into stupendous waves higher than 60 feet tall: That would be almost high enough to inundate the White House. Here...

Astronomy: A rotating system of satellite galaxies raises questions  

Basel, Switzerland (SPX) Feb 15, 2018 Astronomers have examined the distribution and movement of dwarf galaxies in the constellation Centaurus, but their observations do not fit with the standard model of cosmology that assumes the existence of dark matter. The international team of researchers led by the University of Basel reported their findings in the journal Science. Like other large galaxies, our Milky Way is surrounded

Animal diversity improves reproducibility of pre-clinical research  

Pre-clinical animal research is typically based on single laboratory studies conducted under highly standardized conditions.

First Video of DNA Organization Settles Scientific Debate  

For all its precise helical structure, the DNA inside our cells is a mess. When a cell isn't preparing for the process of splitting itself in two, our DNA lies in a massive tangle inside the cell nucleus; a strand more than six feet in length jumbled like an earbud cord. But when it comes time to undergo cellular division, this disorderly strand must be packaged neatly into chromosomes to be passed onto daughter cells — stuffed into a space much tighter than before. Around and Around ...
