Sediment Problems at Whites Creek

WhitesCreek Journal - June 30, 2015 - 5:24pm
We had just over one inch of rain last night here at our end of the creek. This is what the water quality looked like at 10:50 am today.Not a sign of a sediment problem. 6 and a half hours later the water from Piney Creek reached us. This is what it looks like as of a few minutes ago... I don't begrudge what you do on your land as long as you realize you are part of the larger system

Location isn't everything but timing is for certain spawning fish

Science News Daily - June 30, 2015 - 2:52pm
Each year, hundreds to thousands of fish aggregate at highly predictable times and locations to spawn, producing larvae that will spend at least a month in the plankton before settling to reef habitat. The larvae of some species of reef fish appear to survive better depending on the timing of when they were spawned, according to new research.

Folate biomarkers determined

Science News Daily - June 30, 2015 - 2:15pm
An international paper on folate biomarkers is part of an initiative to provide evidence-based guidance for the global nutrition and public health community. The comprehensive study on folate, an essential B vitamin required for DNA synthesis and normal growth and development, represents a consensus of the top folate scientists globally. A major birth defect affecting the spinal cord -- spina bifida, for example -- and brain can be prevented by maternal consumption of sufficient folate prior to and during the very early stages of fetal development.

High-fat diet may alleviate mitochondrial disease

Science News Daily - June 30, 2015 - 12:53pm
Mice that have a genetic version of mitochondrial disease can easily be mistaken for much older animals by the time they are nine months old: they have thinning grey hair, osteoporosis, poor hearing, infertility, heart problems and have lost weight. Dietary fat, coupled with a natural hormone, can relieve symptoms in these mice, researchers have found.
