A multidisciplinary team of scientists from Spanish universities and research centers has managed to design small synthetic molecules capable of joining to the genetic material of the AIDS virus and blocking its replication.
Biologists have identified a cryptic new species of wild cat living in Brazil. The discovery is a reminder of just how little scientists still know about the natural world, even when it comes to such charismatic creatures. The findings also have important conservation implications for the cats, the researchers say.
When a marine turtle is incidentally by-caught by a longliner, fishermen try to cut the line — without hauling it on board — and release the turtle into the sea. However, research published determines that about 40% of post-released turtles die some months later due to the impact of longline fishing.
