Fluorescing urine signals organ transplant rejection, could replace needle biopsies  

Glowing urine may replace the biopsy needle: In detecting organ transplant rejection, a new nanoparticle has proven much faster and more thorough in the lab than a biopsy. When T cells mount their first attack on the organ's cells, the nanoparticle sends an alarm signal into the urine that makes it fluoresce.

Ocean acidification harms cod larvae more than previously thought  

The Atlantic cod is one of the most important commercial fish species in the world. Recent studies have shown that ocean acidification threatens the early life stages of this species. So far it was hoped that at least the larvae that survive might be more robust and therefore may aid in the adaptation of this population. A new article suggests otherwise.

Because only tiny amounts can be obtained from sea organisms, synthetic production is necessary. Scientists have introduced a new, efficient synthetic route for these two drugs. A key step is the light-controlled activation of a carbon-hydrogen bond.
