New test improves detection of liver cancer
..., they found that the quantities of two particular sugar
groups that appear on the blood proteins varied according to the stage of the disease. Furthermore, these values correlated with the size of the tumor. The ratio of these values forms the basis of the new blood test. The researchers were able to mak...

Measuring nectar from eucalypts
...hat mature forest produced almost 10 times as much sugar
per hectare as recently logged forest. However, because current logging practices result in a mosaic landscape, where some areas are logged and others are left untouched, the impact is far less. An estimate of nectar production at a compartment s...

Researchers find pathway that controls cell size and division
... in large part by a molecule that senses the blood sugar
dependent hormone insulin. Petra Levin, Ph.D., Assistant Professor of Biology at Washington University in St. Louis, and her laboratory have recently identified a trio of enzymes that act in concert to link nutrient availability to cell size in th...
Instant steam takes on MRSA

GI Caramba! Blue tortillas may help dieters and diabetics
...GI are considered healthier as they slowly release sugar
into the bloodstream. This reduces fluctuations in our blood glucose and insulin levels, helping to maintain a steady supply of energy. Low GI foods are said to have long-term health benefits, reducing your risk of heart disease and diabetes as well ...
Discoverer of Sly Syndrome finds way of delivering medicine to fight rare genetic disorder
...he missing enzyme is more than 1,000 larger than a sugar
molecule and so huge it cant get across the blood-brain barrier, which prevents it from reaching the brain. Scientists used a mouse model to figure out how to get the enzyme into the brain. They knew that injections of the missing enzyme into the b...
