A study switches from genetic to metabolic analysis to reconstitute evolutionary process

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A new method for analyzing a living being chemical compositions is tested in Andean plants and attest the genesis of species by means of geographic isolation. Scientific article published August 2017 by Brazilian researchers is based on the analysis of chemical compounds which express specific biogeographic trends at the evolutionary process, validating a Smithsonian hypothesis on the evolution of the genus Espeletia in the process.

Scientists edit butterfly wing spots and stripes

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

An international research team working at the Smithsonian Tropical Research Institute in Panama knocked-out a single control gene in the DNA of seven different butterfly species. In the Sept. 18 Proceedings of the National Academy of Sciences early online edition, they reveal the surprising results of rewiring the WntA gene: a single gene influences the exuberant diversity of butterfly wing patterns in nature.

Kit will identify genetic variations without need for lab analysis

Fundação de Amparo à Pesquisa do Estado de São Paulo
Business Announcement

Tests will identify genetic alterations that can be used to measure meat quality, characteristics of seedlings and plants, or pesticide resistance of disease-transmitting mosquitoes. In developing a simple and portable kit, Brazilian startup Scheme Lab is making companies from multiple market areas less reliable on clinical laboratories and their rather expensive brand of expertise.

Peer-Reviewed Publication

A study on damage to coastal considered only real estate loss. If nothing is done, researchers say, losses might be up to ten times higher if the predicament includes the spreading of flood- and global warming -related diseases.

Coffee and bees: New model of climate change effects

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Areas in Latin America suitable for growing coffee face predicted declines of 73-88 percent by 2050. But bee species diversity may save the day, even if many species in cool highland regions are lost as the climate warms.
