New light shed on circadian rhythms      (via sciencedaily.com)     Original source 

Circadian clocks, which drive circadian rhythms, are entwined with many essential systems in living things including plants, fungi, insects, and even humans. Because of this, disruptions to our circadian clocks are linked to higher disease rates in humans, including certain cancers and autoimmune diseases.

Shining a light on molecules: L-shaped metamaterials can control light direction      (via sciencedaily.com)     Original source 

Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or handedness, could provide a way to identify and sort specific molecules for use in biomedicine applications, but researchers have had limited control over the direction of the waves -- until now.

Frequent mowing puts poisonous weed into survival mode      (via sciencedaily.com)     Original source 

A study has found that frequent mowing of Solanum elaeagnifolium, also known as silverleaf nightshade, may help create a 'superweed.' A professor of entomology and plant pathology has been studying silverleaf nightshade for more than a decade. New findings have shown that the more silverleaf nightshade was mowed, the more it developed ways to avoid destruction. The taproot went down further, nearly 5 feet deep, in the first generation of mowed plants. More spikes popped out on the stem as a defense against caterpillars feeding on the flowers. The flowers became more toxic to caterpillars, leading to less pressure from natural predators.

Key nutrients help plants beat the heat      (via sciencedaily.com)     Original source 

Scientists have discovered some of the molecular mechanisms controlling how plants -- including important crops like soybean and rice -- will respond to rising global temperatures, finding higher temperatures make root systems grow faster, but sustaining this increased growth speed depends on high levels of nitrogen and phosphorus in the soil. The discoveries point to the necessity of nitrogen and phosphorus-rich soil to promote crop growth and create nutritious crops, in addition to aiding a mission to create more resilient crops in the face of climate change.

Shape and depth of ocean floor profoundly influence how carbon is stored there      (via sciencedaily.com)     Original source 

The movement of carbon between the atmosphere, oceans and continents -- or carbon cycle -- regulates Earth's climate, with the ocean playing a major role in carbon sequestration. A new study finds that the shape and depth of the ocean floor explain up to 50% of the changes in depth at which carbon has been sequestered there over the past 80 million years. While these changes have been previously attributed to other causes, the new finding could inform ongoing efforts to combat climate change through marine carbon sequestration.

Transition-metal-free zeolite catalyst for direct conversion of methane to methanol      (via sciencedaily.com)     Original source 

Direct oxidation of methane to methanol is dominated by transition- or noble-metal-based catalysts, thus making the reaction quite expensive. To make the process efficient and cost-effective, researchers developed a transition-metal-free aluminosilicate ferrierite zeolite catalyst that can produce methanol by using methane and nitrous oxide as starting materials. The new catalyst ensures excellent methanol production efficiency, one of the highest recorded rates in the literature thus far.

Aiding the displaced with data      (via sciencedaily.com)     Original source 

In times of crisis, effective humanitarian aid depends largely on the fast and efficient allocation of resources and personnel. Accurate data about the locations and movements of affected people in these situations is essential for this. Researchers have now produced a framework to analyze and visualize population mobility data, which could help in such cases.
