Fertile research: Protein biomarkers of infertility in human sperm

Date: Jan 7, 2014

Author: Steve Down

A team of Chinese scientists has identified several proteins in spermatozoa which are linked with unexplained male infertility in research that could lead to ways of identifying viable sperm.

Milk fraud: Proteins uncover adulteration with cheaper milk

Date: Dec 1, 2013

Author: Steve Down

The distributions of certain proteins on 2D gels can be used to detect the adulteration of milk from rarer animals like the yak or camel with milk from the cow or goat.

Global micronutrient testing: Protein biomarkers reflect vitamin levels

Date: Nov 1, 2013

Author: Steve Down

The levels of micronutrients in undernourished children have been measured indirectly by their association with particular proteins, eliminating the need for individual tests for vitamins and minerals.

Venom variability: Genetic influences in the pit viper

Date: Oct 16, 2013

Author: Steve Down

The venom proteomes of young jararaca pit vipers that were raised under the same living conditions differ from each other from a very early age, suggesting that the variations are genetically inherited.

Apples unpeeled: Proteome response to wounding

Date: Oct 1, 2013

Author: Steve Down

The effects of wounding on the proteins in Golden Delicious apples has been studied by European scientists to help find ways of stimulating defence mechanisms in the fruit to reduce postharvest losses.
