In experiments involving mice, the team found that they produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals' circulation. This goes against the decades-long assumption that bone marrow produces all of our blood components.
Researchers from the University of California, San Francisco also discovered a previously unknown pool of blood stem cells that makes this happen inside the lung tissue — cells that were incorrectly assumed to mainly reside in bone marrow.
"This finding definitely suggests a more sophisticated view of the lungs — that they're not just for respiration, but also a key partner in formation of crucial aspects of the blood," says one of the researchers, Mark R. Looney.

And when it conducted the survey again in 2016, it found that exchange students thought that U.S. education was even less challenging than before.
Last Year a team of engineers from MIT and Harvard has developed an origami flat-pack Robot[youtube.com] which can fold itself and crawl away without any human intervention.
But now a Binghamton University engineer says this technique can be applied to building batteries, too. The battery generates power from microbial respiration, delivering enough energy to run a paper-based biosensor with nothing more than a drop of bacteria-containing liquid. This method should be especially useful to anyone working in remote areas with limited resources. The total cost of this potentially game-changing device is "Five cents".
