An amazing international gathering of scientists and
engineers
in the Spring of 2006 at Georgia Tech revealed fascinating
research
projects from the bio-design for aquatic propulsion, to the homeostasis

Home-O-stasis: Dynamic Equilibriums in Solar Homes of the
Southeast
Headed by project managers Chris Jarrett, Ruchi
Choudhary and Franca Trubiano, the latest
advances in building integrated photovoltaics (BIPV)
will be integrated within the design of an innovative low energy house
exhibiting the highest level of excellence in architectural design,
construction and comfort. Building on shared research interests in
ecological principles of design, building design performance, and
materials research, the program managers will coordinate the
interdisciplinary team with the goal of achieving substantial
innovation in the research and development of solar energy housing, its
technology, implementation and testing.

Engineers discover why toucan beaks are models of
lightweight strength Marc A. Meyers, a materials scientist
and professor of mechanical and aerospace engineering at UCSD's Jacobs
School of Engineering, and graduate students Yasuaki Seki and Matthew
S. Schneider reported that the secret to the toucan beak's lightweight
strength is an unusual bio-composite. The interior of the beak is rigid
"foam" made of bony fibers and drum-like membranes sandwiched between
outer layers of keratin, the protein that makes up fingernails, hair,
and horn.
Natural adhesive systems of marine mussels, Mytilus
edulis
This illustration shows the Atlantic Blue Mussell, Mytilus edulis, and
its adhesive structure–the byssus with byssal threads and
byssal plaque–and includes a closer look at the byssal thread
and plaque and the individual adhesive proteins with respect to a
substrate surface.
Chemists are increasingly looking to Nature as a
source of inspiration
The use of naturally sourced molecules in synthetic organic
chemistry can provide significant benefits, either as
shortcuts to complex chemical structures or to catalyse chemical
reactions towards a desired end-result. One such biomolecule, vitamin
B12, has a number of useful functions.
Silk may be able to help repair damaged nerves
"The picture shows two things: reddish coloured processors, which are
the nerve fibres growing along the silk; and blue supporting cells,
called Schwann cells, which are very important in supporting nerve
regeneration." John Priestly, a neuroscientist from Queen Mary's School
of Medicine and Dentistry, London

Biomechanics and Hydrodynamics of jet-propelled
swimming in jellyfish
Professor William Megill is a Lecturer (Asst Prof) in Biomimetics at
the University of Bath, England. His PhD was in Biomechanics at the
University of British Columbia. He has been working with marine mammals
since 1990, interested first in dolphin and killer whale acoustics
before turning to baleen whale ecology and now to physiology. He
studied the ecology of blue, fin and humpback whales in the Gulf of St.
Lawrence for several years, then moved to the west coast to study
biomechanics.
The Lobster All-Sky X-ray Monitor:
The lobster is the inspiration for a new type of European X-ray
telescope. The observatory is designed to have an extremely wide field
of view - just as the crustacean manages with its vision. The animal
achieves this using a huge array of tiny channels that focus light by
reflection, rather than by bending it through lenses found in human
eyes. A UK-led team is now building a similar set-up for a telescope
that will sweep the sky for sudden, violent events, such as black holes
swallowing stars.

Cicada Escape Response and MEMS
Escape orientation in arthropods is a highly stereotyped, quick and
precise behavior based on a proper recognition of stimuli announcing
imminent danger from a predator attack. The escape behavior is
triggered by physical stimuli which need to be detected (air-flow,
pressure, sound, vibrations, mechanical forces,…), locally
amplified and filtered by specialized sense organs, transmitted,
processed and integrated into a perception pattern which will control
response.
The Control of Aerodynamic Maneuvers in Fruit Flies
Dickinson, M., California Institute of Technology, Pasadena
Fruit flies alter flight direction by generating rapid, stereotyped
turns, called saccades. The successful implementation of these quick
turns requires a well-tuned orchestration of neural circuits,
musculo-skeletal mechanics, and aerodynamic forces. The changes in wing
motion required to accomplish a saccade are quite subtle, as dictated
by the inertial dynamics of the fly's body. A fly first generates
torque to begin accelerating in the intended direction, but then must
quickly create counter-torque to decelerate. Several lines of evidence
suggest that the initial turn is initiated by visual expansion, whereas
the subsequent counter-turn is triggered by the gyroscopic halteres.
This integrated analysis indicates how the functional organization of
neural circuits controlling behavior is rigidly constrained by the
physical interaction between an animal and the external world. Also,

Richard Bonser and keratin properties
Feather keratin occurs in a 'b-sheet' configuration which is differs
from the a-helices that occur in mammalian keratins. If mammalian
keratins are stretched in steam, then they develop a b-sheet
configuration, so imagining a very stretched spring gives one some idea
of the form of avian keratin.

'Frog's glue' could mend knees
"We assumed the substance would be toxic, but when we found it wasn't,
it made sense to explore it as a medical adhesive" said environmental
biologist Mike Tyler. When set, it was flexible and had a porous
structure that should make it permeable to gas and nutrients, which
would encourage healing.
Blue Crab Nano-Sensor Detects Dangers
A substance found in crab shells is the key component in a nanoscale
sensor system developed by researchers at the University of Maryland's
A. James Clark School of Engineering. The sensor can detect minute
quantities of explosives, bioagents, chemicals, and other dangerous
materials in air and water, potentially leading to security and safety
innovations for airports, hospitals, and other public locations.
Jumping Robots: inspiration from
kangaroos, locusts, grasshoppers, chameleons (tongue), flying squirrels
Biomimeticists are looking at how to incorporate flying and jumping.
Among them is Keith Paskins of the University of Bath, who is trying to
mimic flying squirrels. The squirrels have floppy skin attached to
their wrists and ankles, which they can stretch out to make a gliding
surface. The animals also appear to be able to control their gliding
through rapid movements while in the air.
