Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless
PHILADELPHIA − Concentrated chemicals derived
from green tea dramatically boosted production of a group of key detoxification enzymes in people with low levels of these beneficial proteins, according to researchers at Arizona Cancer Center. These findings, published in the August issue of Can...
Role of thyroid hormones in slumber under investigation at Rutgers

UCLA scientists produce functioning neurons from human embryonic stem cells
...s study showed that two embryonic stem cells lines derived
in similar manners, and therefore expected to behave similarly when differentiating, did not. Using the same techniques to prod the two embryonic stem cells lines to differentiate, Sun found that one line had a bias to become neurons that are found i...

...here the abundant biology is fueled by methane gas derived
from ancient carbon in the sediments, Johnson says. The glass sponges so-called because their skeletons are made of silica (the same material as beach sand) come in un-sponge-like shapes similar to cups and funnels. They range in color from creamy...
