Teachers have emerged as some of the biggest heroes during Monday s devastating tornado in Oklahoma. There have been accounts of teachers shielding students with their own bodies and directing children

I m amazed that he walked out of the building alive, Purcell told CBS News, referring to her 8-year-old son Kamden. Her 15-year-old son, Kigan, attends a different school, and was safe. I had to try and stay calm, said Purcell, when she found out that her younger son s school was nearly destroyed by the twister. It was kind of scary, said Kamden. She [the teacher] told us to go under our

Trenda Purcell said she credits her son s teacher with saving her child, along with the other kids in his class. I then hugged her just as hard as I did Kamden because I felt that she helped save my son s life. I mean all those kids that she had in th

In fact, to shrink standard transistors down small enough to keep Moore Law alive, we need to control the deposition of atoms in silicon to within 10s of atoms鈥攁nd that close enough to the limits of physics that it seems practically impossible right now. But a team of NASA researchers think they have a solution鈥攊n the form of the very same vacuum tube technology that transistors themselves superseded. Actually, we ;re not talking the kinds of vacuum tubes used in those early computers, but rather vacuum transistors: the same physical idea, just shrunk right down to miniscule dimensions. And at that scale, it turns out, many of the positive characteristics of vacuum tubes remain, without the big downslide of low efficiency and massive heat generation . Indeed, a report in IEEE Spectrum reveals that transistors which include a small vacuum can draw electrons through themselve
