In Situ 3D Bioprinting: Impact of Cross‐Linking on the Adhesive Properties of Hydrogels
Advanced Functional Materials, EarlyView.In situ 3D bioprinting enables the direct deposition of cell‐laden, adhesive biomaterials for on‐site tissue regeneration. This review provides a comprehensive overview of how cross‐linking influences the bioadhesive properties of hydrogels used in 3D bioprinting, highlighting cross‐linking triggers, bioadhesion mechanisms, polymer interpenetration ...

Cicada (Tibicen linnei) steers by force vectoring
Theoretical and Applied Mechanics Letters, 2016 To change flight direction, flying animals modulate aerodynamic force either relative to their bodies to generate torque about the center of mass, or relative to the flight path to produce centripetal force that curves the trajectory.

Hoverflies: the garden mimics. [PDF]
, 2008 The article offers information on hoverflies, a kind of fly that has bright colours and darting flight. Many of these brightly coloured hoverflies look like bees or wasps, and they use this to protect themselves.

Matching times of leading and following suggest cooperation through direct reciprocity during V-formation flight in ibis [PDF]
, 2015 One conspicuous feature of several larger bird species is their annual migration in V-shaped or echelon formation. When birds are flying in these formations, energy savings can be achieved by using the aerodynamic up-wash produced by the preceding bird ...

Strategies for Loading and Releasing Peptide Therapeutics in Biodegradable Carriers
Advanced Functional Materials, EarlyView.A biodegradable carrier‐based peptide delivery system is a powerful treatment platform for diverse diseases, owing to its superior therapeutic efficacy and low toxicity. This review examines the conventional peptide‐loaded carrier fabrication process and its current limitations.

Advanced Functional Materials, EarlyView.The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.

The wake dynamics and flight forces of the fruit fly Drosophila melanogaster [PDF]
, 1996 We have used flow visualizations and instantaneous force measurements of tethered fruit flies (Drosophila melanogaster) to study the dynamics of force generation during flight.

The Flight of Birds and Other Animals [PDF]
Aerospace, 2015 Methods of observing birds in flight now include training them to fly under known conditions in wind tunnels, and fitting free-flying birds with data loggers, that are either retrieved or read remotely via satellite links. The performance that comes to light depends on the known limitations of the materials from which they are made, and the conditions ...

Advanced Functional Materials, EarlyView.Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.
