Scientists at the Pentagon have completed a round of testing on a device that enables lasers to talk.
This developer plans to build 800 MW of renewables plus storage
The Energy Department said that 41 states had at least one installed wind turbine as of January 1.
Watch: Viruses self-assemble into antibacterial gel
A hydrogel incorporating billions of bacteriophages forms a material that is not only self-healing but also offers antibacterial services for medical and environmental applications.
Students develop alogrithm to prevent hackers from viewing smart home footage
Engineering students from Canada’s Simon Fraser University (SFU) have developed an artificial intelligence (AI)-driven privacy shield that scrambles the images of occupants captured by smart home security systems vulnerable to hacking.
First evidence of atmospheric mercury nanoparticles
A previously unknown form of atmospheric mercury has been documented by researchers from McGill University, Canada, in urban air samples from Montreal.
Designers create anti-facial recognition masks to thwart public surveillance cameras
In an effort to thwart the controversial facial recognition algorithms in public surveillance cameras, designers from Poland-based design studio have devised an anti-facial recognition mask.
Reducing routine maintenance costs of engine generator sets with new portable oil analysis tools
It is important to know the type of contaminant in the oil because it provides symptoms of the engine condition.
Stress research could help first responders stay healthy
Researchers plan to analyze measures of molecular activity to create new ways to monitor and predict the effects of stressors on the body.
Sensors to monitor conditions in deep, unconventional oil reservoirs
The sensors would be carried into the wells along with proppants that are used to keep the wells flowing.
Managing earthquake risk from oil and gas operations
The team's study area was in Oklahoma, where much fracking activity and wastewater injection has been carried out, and where there have been several induced earthquakes producing damage.
Watch: Microrobots designed to travel and treat the GI tract
A microrobotic platform for precise delivery of drugs within the gastrointestinal tract has been engineered by researchers from California Institute of Technology and Washington University in St. Louis.
Researchers on the path toward developing salt-resistant pavement
Researchers from Brunel University London have developed a new concrete formula that will absorb considerably less salt than traditional concrete, thereby reducing corrosion and deterioration of roadways.
Dressing actively contracts to close wounds
An adhesive alginate-based hydrogel is combined with a thermoresponsive polymer that both repels water and shrinks at around 90° F.
How the world’s first large-scale electric excavator works
The 25 tonne Cat 323F Z-line excavator is nearly identical to the diesel-powered Cat 323F excavator, except its diesel engine has been replaced with an electric powertrain.
Watch: A moonlit tribute to an Apollo pioneer
The tribute was created by positioning more than 107,000 mirrors at the Ivanpah Solar Facility in the Mojave Desert to reflect the light of the moon.
Scientists develop contact lens capable of 'zooming in'
Scientists at the University of California, San Diego, have developed a contact lens that can be controlled by eye movements.
Watch: Water desalination with solar steam technology
A solar steam generation system designed to desalinate seawater harvests salt in addition to producing potable water.
Missile defense systems could learn a lot from a dragonfly
Simulated dragonflies successfully caught their prey using computer algorithms designed to mimic the way a dragonfly processes visual information while hunting.
Bearing terms and calculations every design engineer should know
When sized and used properly most bearings will operate for many years without requiring replacement. Knowledge of bearing life and load terminology and calculations will help the design engineer with bearing selection.
Gel-like gap filler improves cooling performance
The thermal interface material delivers a thermal conductivity of 1.3 W/m-K with a thermal resistance as low as .50° C/in2/W.
