- NASA used cadavers to test Orion moonship
- NASA officials recognized last week that dead bodies were used to develop Orion landing systems. According to NASA, 'three human bodies were used in the tests at Ohio State University Medical Center' in 2007. Even if the results of the experiments helped NASA, one of its spokesman said that the...

- Towards low-cost LED lighting
- You all know that incandescent bulbs are pretty inefficient, converting only 10% of electricity into light -- and 90% into heat. Light-emitting diodes, or LEDs, could soon replace incandescent and compact fluorescent bulbs in our homes. They are more efficient and environmentally friendly. But LED lights are currently too expensive...

- Looking at single atoms of hydrogen
- As you probably know, graphene is a one-atom-thick sheet of carbon atoms packed in a dense two-dimensional honeycomb lattice. And it recently became very popular recently as a basis for ultra-fast transistors. Now, according to Science News, U.S. researchers are using graphene to image individual hydrogen atoms via a standard...

- A super-resolution x-ray microscope
- Swiss researchers have developed a very-high-resolution x-ray microscope. Their approach combines two well-known microscopy techniques, coherent diffractive imaging CDI and scanning transmission x-ray microscopy STXM. As a result, the new system offers both the high penetration power of x-rays and high spatial resolution. This method will allow other scientists to...

- Magic mushrooms to treat cancer anxiety?
- In a 2006 study, U.S. researchers have shown that psilocybin, a substance contained in 'sacred mushrooms,' produced substantial spiritual effects -- when administered under controlled conditions. The scientists recently interviewed the volunteer subjects and they've noted that most of them 'continued to say 14 months later that the experience increased...
