When a shark is spotted in the ocean, humans and marine animals alike usually flee. But not the remora – this fish will instead swim right up to a shark and attach itself to the predator using a suction disk located on the top of its head. While we know why remoras attach to larger marine animals – for transportation, protection and food – the question of how they attach and detach from hosts without appearing to harm them remains unanswered.
Eric Gaucher, associate professor in Georgia Tech's School of Biology, was named as one of 14 young faculty from seven nations to receive an early career grant by DuPont. The DuPont Young Professor program is designed to help promising young and untenured research faculty begin their research careers.The $75,000 award is unrestricted and not tied to a specific research project.
A new study of both computer-created and natural proteins suggests that the number of unique pockets – sites where small molecule pharmaceutical compounds can bind to proteins – is surprisingly small, meaning drug side effects may be impossible to avoid. The study also found that the fundamental biochemical processes needed for life could have been enabled by the simple physics of protein folding.
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living in the southern United States.
