Several new studies find no connection between working
the night shift and breast cancer risk. Researchers
from Oxford University followed a total of 800-thousand
women in three large studies and found no increased
risk. The findings question the World Health Organization's
2007 assessment that shift work could increase the
chance of developing cancer.
Scientists from Harvard and Massachusetts General
Hospital say they've come up with a blood sugar test
that is 50 percent more accurate than the current
test widely used by diabetics. Researchers say the
new test is more precise because it factors in the
age of each patient's red blood cells. They say the
new model could lead to more precise diagnosis, monitoring
and better-tailored treatments.
And new research concludes there's a cap to how old
we can possibly live - and we've already reached it.
Researchers from Albert Einstein College of Medicine
calculated the maximum human lifespan peaked in the
mid-nineties. They put the average maximum human life
span at 115 years and the absolute limit of human
lifespan at 125. Those are some of the day's top health
stories. Jamie Yuccas, CBS News, New York.
