New feather findings get scientists in a flap
Scientists have revealed that feather shafts are made of a multi-layered fibrous composite material, much like carbon fiber, which allows the feather to bend and twist to cope with the stresses of flight. Since their appearance over 150 million years ago, feather shafts (rachises) have evolved to be...
Facetless crystals that mimic starfish shells could advance 3-D-printing pills
In a design that mimics a hard-to-duplicate texture of starfish shells, engineers have made rounded crystals that have no facets.
Impact of offshore wind farms on marine species
Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. Scientists have now reviewed the pot...
Bias in transportation system design exposed
America''s streets are designed and evaluated with an inherent bias toward the needs of motor vehicles, ignoring those of bicyclists, pedestrians, and public transit users, according to a new study.
Power of thorium for improved nuclear design explored by scientists
The development of a radical new type of nuclear power station that is safer, more cost-effective, compact, quicker and less disruptive to build than any previously constructed is underway.
Demand high for engineers in Midwest
Engineering students preparing to take their sheepskin and depart into the world of change orders and service requests are finding no shortage of companies wanting to take their resumes.
Long-span construction: Ultra light-weight cloud arch architectural technology for sustainable construction
First-of-its-kind, light-as-cloud architectural technology boasts lower setup cost and time, and is set to revolutionize long-span architecture and construction.
First comprehensive mesh-free numerical simulation of skeletal muscle tissue achieved
Engineers have completed the first comprehensive numerical simulation of skeletal muscle tissue using a method that uses the pixels in an image as data points for the computer simulation -- a method known as mesh-free simulation.
Discovery of a new way to make foams could lead to lightweight, sustainable materials
Researchers have developed a new type of foam - called capillary foam - that solves many of the problems faced by traditional foams. The foam could be used to make lightweight, sustainable materials.
Aircraft safety: New imaging technique could detect acoustically ''invisible'' cracksStories 1 - 10 of 139
The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems.
