Chemists synthesize unique anticancer molecules using novel approach      (via sciencedaily.com)     Original source 

Nearly 30 years ago, scientists discovered a unique class of anticancer molecules in a family of bryozoans, a phylum of marine invertebrates found in tropical waters. The chemical structures of these molecules, which consist of a dense, highly complex knot of oxidized rings and nitrogen atoms, has attracted the interest of organic chemists worldwide, who aimed to recreate these structures from scratch in the laboratory. However, despite considerable effort, it has remained an elusive task. Until now, that is. A team of chemists has succeeded in synthesizing eight of the compounds for the first time using an approach that combines inventive chemical strategy with the latest technology in small molecule structure determination.

Increasingly similar or different? Centuries-long analysis suggests biodiversity is differentiating and homogenizing to a comparable extent      (via sciencedaily.com)     Original source 

The tendency of communities and the species within them to become more similar or more distinct across landscapes -- biotic homogenization and differentiation -- are approximately balanced, according to a new study. This analysis is the first of its kind to provide a comprehensive assessment of how local and regional biodiversity changes combine across landscapes over centuries.

Advanced artificial photosynthesis catalyst uses CO2 more efficiently to create biodegradable plastics      (via sciencedaily.com)     Original source 

A research team that had previously succeeded in synthesizing fumaric acid using bicarbonate and pyruvic acid, and carbon dioxide collected directly from the gas phase as one of the raw materials, has now created a new photosensitizer and developed a new artificial photosynthesis technology, effectively doubling the yield of fumaric acid production compared to the previous method. The results of this research are expected to reduce carbon dioxide emissions and provide an innovative way to produce biodegradable plastics while reusing waste resources.

Asexual propagation of crop plants gets closer      (via sciencedaily.com)     Original source 

When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered without fertilization, as researchers have shown. Their findings open up new avenues for the asexual propagation of crop plants.

Root microbes may be the secret to a better tasting cup of tea      (via sciencedaily.com)     Original source 

You'd think the complex flavor in a quality cup of tea would depend mainly on the tea varieties used to make it. But a new study shows that the making of a delicious cup of tea depends on another key ingredient: the collection of microbes found on tea roots. By altering that assemblage, the authors showed that they could make good-quality tea even better.

Controlling root growth direction could help save crops and mitigate climate change      (via sciencedaily.com)     Original source 

Scientists have determined how the well-known plant hormone ethylene is crucial in controlling the angle at which roots grow. The findings can be used to engineer plants and crops that withstand the environmental stresses of climate change and drought, and perhaps to create plants that remove carbon dioxide from the atmosphere and store it deep underground to help mitigate climate change.
