... over-absorption by soil. Over time, this can also result in soil salination and loss of agricultural productivity. Neither are factors in hydroponic greenhouses, which do not require high-quality arable land to function in the first place.

The result of the search for Smac mimics was a molecule the researchers called "Compound 3." "The way we arrived at Compound 3 was serendipitous," said Wang. "At first we thought that just mimicking the last four amino acids of Smac was the way to go, but we w...Research suggests unborn children may be at risk from environmental pollution

Preece and his team at Bristol set out to determine the extent of placental transfer through a series of bio-distribution measurements and ex vivo experiments using donated human placentas. They found reasonable correlation be...Broken arms and collateral damage: clues to predator-driven evolution
...ds usually lose---and regenerate---their arms as a result of attacks by fish, Baumiller and Gahn reasoned that arm regeneration in fossil crinoids would be a good indicator of predator-prey interactions in the geologic past. To test their idea, they examined more than 2,500 Paleozoic crinoids for evidence o...Analysis fingers causes of desertification
...lts support the notion that desertification is the result of irreducibly complex processes. Rather, the analysis suggests that desertification is best explained by a limited number of recurrent pathways that include regionally distinct combinations of factors and feedbacks.

Caldwell hopes that the C. elegans convulsion model may help decode the mysteries of epilepsy and perhaps lead to better treatments for seizures.

In fact, there was a family of four different VPS37 proteins that the scientists named VPS37A-D.
