... gene expression of these enzymes, which can be an advantage to people with low levels to start with. Green tea has long been of interest to researchers given studies that have shown populations in which it is often consumed, such as the Chinese and Japanese, generally have lower rates of cancer. To find out...X-ray images help explain limits to insect body size
...change as their body sizes increase. The team took advantage of richly detailed X-ray images they produced at the APS to examine the dimensions of tracheal tubes in four beetle species, ranging in body mass by a factor of 1,000. Overall, they found that larger beetle species devote a disproportionately great...Circadian clock controls plant growth hormone

Auxin tells shoots to grow away from the ground and toward light and water. Charles Darwin conducted early experiments that showed ...deCODE discovers cause of major subtype of glaucoma

The deCODE team discovered the variants by first analyzing more than 300,000 SNPs in Icelandic and Swedish glaucoma patients and control subjects, utilizing the Illumin......ol plants, but that neither had a significant cost advantage over the other. Comparing the costs of biofuels is complicated by the fact that most studies rarely employ the same bases for economic evaluations. Differences in assumed plant size, biomass costs, method of project financing, and even the year in ...The 'female advantage' in kidney disease does not extend to diabetic women

For reasons still unclear, diabetic women -- regardless of age -- are diagnosed with kidney and heart diseases almost as frequently as men. What is it about diabetes that predisposes a woman to de......s. Self-pollination, or selfing, confers a major advantage to weedy species. Aselfing plant can invade new territory by itself and colonize it alone. The potential downside -- a nasty case of inbreeding depression -- isaverted by rare sexual breeding.

The breed society is taking advantage of reduced rate testing by being responsible for administering samples, invoicing and reporting results.

...sing their own cells rather than a donor's has the advantage that their immune system is less likely to reject the treatment. Although Mller glial cells are present in the human eye, it is not clear whether they already automatically repair the retina in some people but not in others.

One cubic centimeter of the aerogel could have a surface area as large as a football field, according to Kanatzidis.
