The first research to actively analyze adult male sea turtles (Caretta caretta) using satellite tracking to link geography with pollutants has revealed the potential risks posed to this threatened species by manmade chemicals. The research, published today in Environmental Toxicology and Chemistry, examines the different levels of chemicals in the blood of both migratory and residential turtles.

Using a web app that is provided online, participants are asked to attempt to identify certain constellations and, if they can, rate them against magnitude charts. The project tracks the increasing problem of disappearing darkness, which can interrupt the cycles of plant and animal life, eventually to a fatal degree.

A device the size of a deck of playing cards that can track temperature, humidity, light and barometric pressure is moving from the shipping world to the realm of research to help develop a better understanding of how the climate is changing.

Scientists at the University of Miami Rosenstiel School of Marine & Atmospheric Science have discovered a technique to track urban atmospheric plumes thanks to a unique isotopic signature found in vehicle emissions.

In the growing global battle against substandard and counterfeit medicines, the Promoting the Quality of Medicines (PQM) program has launched a new, public database of medicines collected and analyzed in collaboration with stakeholders from countries in Africa, South America and Southeast Asia. Free of charge and available to anyone with access to the internet, the Medicines Quality Database (MQDB) includes information on the quality of medicines collected from a variety of sources. To date, more than 8700 records of tested samples collected from Ghana, Laos, Vietnam, Cambodia, the Philippines, Thailand, Peru, Guyana and Colombia have been entered into the database.

thanks to a research project that is the next best thing to time travel, DeJong is measuring the duck eggs in several museum collections - from the Smithsonian Institution, in this case, where Bendire was the first curator of the discipline known as oology, or the study of birds' eggs. When her project is done, DeJong will have assembled and analyzed a metrics database on perhaps 60,000 duck eggs representing at least 40 species and subspecies of ducks found in North America.
