X-ray astronomy is only 50 years old but nothing shows the progress of the technology like a new view of a supernova scientists watched over a thousand years ago. 

Some people just don't know how to put patterns and colors together. Or anything about style.

Some of that is cultural, of course. No one really wears corsets any more, for example, and good luck finding anyone outside the Mid-East who knows what a caftan is. Some new technology may herald a future for fashion, its creator claims; computerized fabrics that change their color and their shape in response to movement.

The most powerful batteries on earth are only a few millimeters in size but a cellphone version can jump-start a dead car battery and then recharge the phone in the blink of an eye. 

Led by Professor William P. King, researchers at the University of Illinois at Urbana-Champaign show that the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.

When many of us were kids, water-transfer printing meant a fake tattoo. For our children, it will mean peel-and-stick versions of solar cells that charge cell phones, change the tint on windows, or power their toys. 

Peel-and-stick, or water-assisted transfer printing (WTP), technologies were developed by a group at Stanford and have been used before for nanowire based electronics. A new partnership between Stanford University and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has conducted the first successful demonstration using actual thin film solar cells, NREL principal scientist Qi Wang said.

The latest national survey of 100% biodiesel (B100) "blend stock" samples by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications, a big improvement over 2007 when less than half of the samples met quality specifications. 

The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers, along with reliable operation of the nation's vehicles powered by biodiesel blends.  

One group writing in the European Heart Journal found that digoxin increases mortality in patients with atrial fibrillation (AF). Another group just found that it did not and published in the same journal.

They used the same data.
