Breaking down backbones
A new study is challenging the long-held belief that specialization in mammal backbones date back to the earliest land animals.

When mammal ancestors evolved flexible shoulders, their backbones changed too
Dolphins swim, horses gallop, and humans walk on two legs — mammals are able to move in lots of different ways. That's because we have unique backbones. And scientists exploring how mammals' backbones evolved have discovered that the key to our complex spines lies in mammals' flexible shoulders.

Hookworms employ live fast/die young strategy in fur seal pup hosts
Hookworms exploit a live fast/die young strategy in their South American fur seal pup hosts, report Morris Animal Foundation-funded researchers at the University of Georgia. As a result, they often kill their host, rather than finding a happy equilibrium. Scientists are concerned that this type of hookworm infection could eventually pose a risk to critically endangered populations of fur seals.

AI could help drones ride air currents like birds
Birds have long inspired humans to create their own ways to fly.

Using one quantum dot to sense changes in another
Quantum dots are nanometer-sized boxes that have attracted much scientific interest for use in nanotechnology because their properties obey quantum mechanics and are requisites to developing advanced electronic and photonic devices. Quantum dots that self-assemble during their formation are particularly attractive as tunable light emitters in nanoelectronic devices and for studying quantum physics

Chitinase as 'burnt-bridge' Brownian monorail efficiently hydrolyzing recalcitrant biomass
Molecular motors convert energy into unidirectional mechanical motion. Most biomolecular motors in cells use adenosine triphosphate (ATP) as a chemical energy source. Recently, however, Serratia marcescens chitinase A (SmChiA) has been rediscovered as a molecular motor working in extracellular environments without using ATP. Similar to a monorail car (Fig. 1), SmChiA has cleft-like polysaccharide
