Gene regulation, not just genes, is what sets humans apart
...eaters, for the most part, and would not last long away from their fruit-rich forest. The sugars in their diet are relatively simple to break down and convert to cellular fuel. Humans, on the other hand, eat a wider array of foods, including many the chimps would simply not be able to digest like starchy ...Circadian clock controls plant growth hormone
...by circadian rhythms. Auxin tells shoots to grow away from the ground and toward light and water. Charles Darwin conducted early experiments that showed how auxin affects plant growth. Most plants and animals have an internal clock that allows them to match their activities to the time of day or season ...Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
...oductivity. More vegetation sequesters more carbon away from the atmosphere in plant biomass. This is actually good news from a greenhouse gas perspective, Turetsky said. However, the report also cautions that this flooding associated with collapsing permafrost also increases methane emissions. Meth...1 of deep ocean's most turbulent areas has big impact on climate

... lead to that result." No-till agriculture does away with plowing, which often involves stripping crop stubble from fields before deeply turning the soil. Often a plowed field will be disked to remove stubble and weeds. No-till agriculture uses disking to turn only the top layer of soil.

During heavy rains, sewage systems can get overwhelmed and result in untreated sewage flowing directly out to sea.

While lactating mice will ordinarily attack male intruders and reject their courtship behaviors, the mutant females were docile toward males and appeared highly receptive ...Beyond Mesopotamia: A radical new view of human civilization reported in Science

Once a cell is infected, the presence of THC may also promote the cellular events that turn it cancerous, t...Under magnetic force, nanoparticles may deliver gene therapy

Previous researchers had shown that magnetically driven nanoparticles could deliver DNA in cell cultures, but ours is the first delivery system that is biodegradable, and therefore, safer to use in people, said Levy. This delivery s...Stem cell therapy rescues motor neurons in ALS model

An important caveat, however, is that while the motor neurons within the spinal cord are protected by the growth factor, their ability to maintain connections with the muscles they control was not observed.
