Beta-blockers before surgery linked to lower risk of heart-related events
Science Daily - 18 Nov 2013 23:28
Giving beta-blocker medication to patients with heart disease undergoing noncardiac surgery appears to be associated with a lower risk of death and major adverse cardiovascular events 30 days after surgery in patients wi...
Higher than normal levels of Vitamin B12 may indicate cancer risk
Science Daily - 18 Nov 2013 23:28
Vitamin B12 (cobalamin [Cbl]) is essential for maintaining healthy bodily function, but higher than normal levels (reference range 200-600 pmol/L) may indicate that a patient is at risk of developing certain cancers, acc...
Rural, southern regions lack annual training in CPR

The big male nose: Why men's noses are bigger than women's
Science Daily - 18 Nov 2013 23:00
Why are men's noses bigger than women's? The answer, according to a new study lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which...
New models predict where E. coli strains will thrive
Science Daily - 18 Nov 2013 22:59
Bioengineers have used the genomic sequences of 55 E. coli strains to reconstruct the metabolic repertoire for each strain. Surprisingly, these reconstructions do an excellent job of predicting the kind of environment wh...
Reading the pancreas through the eye
