Now, scientists have identified certain conditions in the Pacific Ocean that may lead to super-outbreaks over the U.S.' tornado alley.
Researchers are trying to determine if Trans-Niño years, which mark the onset or ebbing of El Niño and La Niña, are the main culprits behind the deadly super-outbreaks. According to the study, fueled by a powerfully interconnected global atmospheric system, as sea-surface temperatures in the Pacific shift the Jet Stream's course during Trans-Niño years, favorable conditions for violent weather in the United States are created.

NASA's HS3 Hurricane Mission Called it a Wrap for 2013
03.12.2013 | NASA's Goddard Space Flight Center
NASA's Hurricane and Severe Storms Sentinel airborne mission known as HS3 wrapped up for the 2013 Atlantic Ocean hurricane season at the end of September, and had several highlights. HS3 will return to NASA’s Wallops Flight Facility in Wallops Island, Va., for the 2014 Atlantic hurricane season.
During the 2013 mission, two unmanned Global Hawks flew from Wallops for the first time. The mission highlights included studying the Saharan Air Layer, following the genesis of a tropical storm, finding a unique hybrid core or center circulation in a redeveloped storm, obtaining measurements on the strongest side of ...
Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as a safe and effective vaccine against this toxin.
This "nanosponge vaccine" enabled the immune systems of mice to block the adverse effects of the alpha-haemolysin toxin from MRSA—both within the bloodstream and on the skin. Nanoengineers from the University of California, San Diego described the safety and efficacy of this nanosponge vaccine in the December 1 issue of ...
Max Planck researchers are able to reveal the spatial structure of chiral molecules
Small difference, large effect: Most biological molecules occur in two variants, an original and its mirror image. As a result, they are related to one another like the left hand to the right.
For instance, the left- and right-handed variant of the same molecule makes lemons smell different from oranges. ...
Scientists at MPQ develop a new model for realizing the Fractional Quantum Hall Effect in lattice systems
It is fascinating how quantum mechanical behaviour of particles at smallest scales can give rise to strange properties that can be observed in the classical world. One example is the Fractional Quantum Hall Effect (FQH) that was discovered about 30 years ago in semiconductor devices.
It is one of the ...
When a chair leg breaks or a cell phone shatters, either must be repaired or replaced. But what if these materials could be programmed to regenerate-themselves, replenishing the damaged or missing components, and thereby extend their lifetime and reduce the need for costly repairs?
That potential is now possible according to researchers at the University of Pittsburgh Swanson School of Engineering, who have developed computational models to design a new polymer gel that would enable complex materials to regenerate themselves.
The article, "Harnessing Interfacially-Active Nanorods to Regenerate Severed Polymer Gels" (DOI: 10.1021/nl403855k), was published ...
