K-State professors discover enzyme responsible for creation of a beetle's hard shell
...pest control, but also help create similar strong, lightweight

materials for aircraft and military armor, Kramer said. "I sometimes speculate that we might help K...
Ancient humans brought bottle gourds to the Americas from Asia
...ners, musical instruments and fishing floats. This lightweight
"container crop" would have been particularly useful to human societies before the advent of pottery and settled village life, and was apparently domesticated thousands of years before any plant was domesticated for food purposes. Radiocarbon dating...
Engineers discover why toucan beaks are models of lightweight strength
...razil 40 years ago, Marc A. Meyers marveled at the lightweight
toughness of toucan beaks that he occasionally fou...ider 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 a...
Frog’s ear canal may provide insights for understanding human hearing loss
... and the bones of the middle ear must be extremely lightweight
in order to transmit ultrasonic vibrations to the inner ear. The presence of an ear canal not only protects A. tormotus' thin and fragile eardrum from the environment, but also lessens the distance between the eardrum and the inner ear, thus allowing...
CU, USDA team to curb two invasive, poisonous vines
.... Like the common milkweed, swallow-worts release lightweight
seeds with featherlike tails that are dispersed by wind and passing deer. Interestingly, between two to eight plants can germinate from each seed. ...
Penguins waddle but they don't fall down, UH researchers say
... birds, such as the rock hopper penguins, were too lightweight
to register data on the mat. King penguins, second in size only to the larger Emperor penguins, are three feet tall on average and can tip the scales at up to 35 pounds. And they were also very eager to perform. "It's almost like playtime for th...
MIT researchers build tiny batteries with viruses
...at cram as much electrical energy into as small or lightweight
a package as possible. The batteries they hope to build could range from the size of a grain of rice up to the size of existing hearing aid batteries. Batteries consist of two opposite electrodes - an anode and cathode - separated by an electrolyte....
Sandia work launched on space shuttle shows live cells influence growth of nanostructures
...dministration laboratory. "Cheap, tiny, and very lightweight
sensors of chemical or biological agents could be made from long-lived cells that require no upkeep, yet sense and then communicate effectively with each other and their external environment," says former UNM graduate student and Sandia consultant He...
Sandia research to focus on early detection of harmful algal blooms
...andia research go as planned, is to develop small, lightweight
devices that could be fielded by oceanographers and marine biologists as part of their regular monitoring systems. In addition to Sandia's Lane and VanderNoot, collaborators include Donald M. Anderson, a senior scientist and director of the Coastal...
Why Popeye only has eyes for spinach

instrument that can measure the levels of lutein and zeaxanthin and provide an indication as to whether low levels of macular pigment may be linked with premature visual impairment. "If the instrument demonstrates that the patient has low levels of...
Study to explore using magnets to correct 'sunken chest'
...ild's breastbone and a second magnet embedded in a lightweight
plastic brace that the child wears under clothing. The attraction between the two magnets holds the brace in place. Because the internal magnet is placed just under the skin during an outpatient visit, the child can go home on the day of the proc...
Dinosaur hearing, listening to muscle noise, quieter cubicles

species with a short basilar membrane can hear higher frequencies than larger species with a longer basilar membrane. Analyzing these and other variables, the researchers suggest that large dinosaurs could mainly hear low frequencies, with a high f...
