Faster, stronger, lighter: New technique advances carbon-fiber composites
These days, aerospace engineering is all about the light stuff: building airplanes with lighter wings, fuselage and landing gear in an effort to reduce fuel costs.
Moth-inspired nanostructures take the color out of thin films
Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film ...
Researchers create highly conductive and elastic conductors using silver nanowires
Researchers from North Carolina State University have developed highly conductive and elastic conductors made from silver nanoscale wires (nanowires). These elastic conductors could be used to develop stretchable ...
Heart-powered pacemaker could one day eliminate battery-replacement surgery
A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves.
Engineers look to the birds for the future of UAVs (w/ video)
(PhysOrg.com) -- Engineers at UC San Diego are mimicking the movement of bird wings to help improve the maneuverability of unmanned aerial vehicles (UAVs).
Robot walks a 40.5-mile ultramarathon without recharge (w/ video)
(PhysOrg.com) -- Pulling an all-nighter and then some, the Cornell robot Ranger set a new world record May 2 by walking 40.5 miles on a single battery charge without stopping or being touched.
New Material Mimics Bone To Create Better Biomedical Implants
(PhysOrg.com) -- A "metal foam" that has a similar elasticity to bone could mean a new generation of biomedical implants that would avoid bone rejection that often results from more rigid implant materials, ...
Gold shapes up as new-age sensor
(Phys.org) —A wearable pressure sensor that is both highly sensitive and cheap to produce could aid the development of prosthetic skin, touch-on flexible displays and energy harvesting, as well as changing ...
Russia to get first private satellite constellation
A Russian startup said Wednesday it will launch several satellites in the coming weeks, the country's first private satellite constellation, to offer maritime monitoring services.
3-D models help researchers study biomechanics behind amazing ant strength
A recent study into the biomechanics of the necks of ants – a common insect that can amazingly lift objects many times heavier than its own body – might unlock one of nature's little mysteries and, quite ...
Scientists use nanoparticles to control growth of materials
(Phys.org) —Growth is a ubiquitous phenomenon in plants and animals. But it also occurs naturally in chemicals, metals and other inorganic materials. That fact has, for decades, posed a major challenge ...
Common junction in pipes can trap bubbles and particles even if materials are flowing freely
(Phys.org) —In a discovery that could eventually have implications for both health and industrial safety, researchers at Princeton University have found that common T-junction intersections in pipes can ...
Tech giants look to skies to spread Internet
The shortest path to the Internet for some remote corners of the world may be through the skies. That is the message from US tech giants seeking to spread the online gospel to hard-to-reach regions.
Good vibrations: Using light-heated water to deliver drugs
Researchers from the University of California, San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences, in collaboration with materials scientists, engineers and neurobiologists, have discovered a ...
