In an instantaneous, 24-hour news cycle, a lot of being made of current U.S. droughts but the 1934 version was 7X larger than other comparable intensity droughts that struck North America between 1000 A.D. and 2005, and nearly 30 percent worse than the next most severe drought that struck the continent in 1580, finds a new analysis.  

Though the American economy remains in a malaise, with alarming numbers of people chronically unemployed for so long they no longer are considered unemployed because they can't get unemployment benefits any more, two areas have been exempt from that - government employees and new college graduates.

Unlike the rest of the economy, those two sections never had negative growth and now hiring is expected to jump a whopping 16 percent for newly minted degree-holders in 2014-15, according to Recruiting Trends, the annual survey by Michigan State University economist Phil Gardner with responses from nearly 5,700 companies. 

Mothers are already responsible for propagating the species, a thankless job which men wisely avoid in all ways, but now they may be tasked with a better diet and exercising more also, because it has been directly associated with a range of improved outcomes at birth by researchers from the University of Adelaide.

They say it is the  biggest study of its kind two papers were published on the findings in BMC Medicine.

The Obama administration only recently banned incandescent bulbs and compact fluorescent bulbs are getting all of the marketing due to generous government subsidies, so light emitting diodes (LEDs) are yet to even get off the cultural ground but researchers are already moving on to their successors. 

Enter carbon electronics.

Electronics based on carbon, especially carbon nanotubes (CNTs), are emerging as successors to silicon for making semiconductor materials. And they may enable a new generation of brighter, low-power, low-cost lighting devices that could challenge the dominance of LEDs in the future and help meet society's ever-escalating demand for greener bulbs. 

It's not a secret that rats carry diseases, they quite literally carried the pests that caused the Bubonic Plague across Europe in the middle ages. But New York City has always felt like their rats were exceptional compared to rats beyond the Hudson River, and so scientists at Columbia University's Mailman School of Public Health trapped 133 Norway rats at 5 sites in New York City, focusing on rats trapped inside residential buildings.

They examined them for identified bacterial pathogens, including E. coli, Salmonella, and C. difficile, that cause mild to life-threatening gastroenteritis in people; Seoul hantavirus, which causes Ebola-like hemorrhagic fever and kidney failure in humans; and the closest relative to human hepatitis C. 

High-resolution cryo-electron microscopy has revealed in unprecedented detail the structural changes in the bacterial ribosome which results in resistance to the antibiotic erythromycin.
