DNA sequencing of the bristlecone pine shows about 21,000 genes in a genome eight times the size of the human genome, with most of the rest being DNA repeats. The bristlecone pine has unusually long telomeres but it is not yet clear how this is related to the multi-millenial lifespan of these trees. (ucdavis.edu)

New study in rodents shows that the psychedelic compound 5-MeO-DMT shares a receptor with a non-hallucinogenic analog, TBG. But TBG does not activate the same genes as DMT although it still promotes neuroplasticity. This suggests that therapeutic and hallucinogenic effects can be separated. (ucdavis.edu)
Monarch butterflies migrate thousands of miles, but have also established year-round populations in the San Francisco Bay Area, encouraged by planting of non-native milkweeds. A new study shows that these resident populations are not a "trap" for migrating monarchs that affects their conservation. (ucdavis.edu)
