Blue Tarantulas Could Improve Screens for TVs, Phones, and Computers

scientists examining the nanoscale topography of the world's largest spiders are part of a more substantial effort to understand and copy the brilliant structural colors in nature.

If you're able to look past the hair, oversized fangs, and profusion of eyes and legs, tarantulas are in reality quite beautiful. You can find Halloween-readyspecimens with deep black bodies and bright rust accents; there are lemon yellows, car-show worthy chromes, and many different electrifying blues.

How To Make A Noiseless Fan Inverter

                                                                                              

This is a DC to AC inverter upgrade project.

I like to use solar energy in my household for lighting, feeding USB chargers and more. I regurarly drive 220V tools with solar energy through an inverter, also using tools around my car powering them from the battery of the car. All this scenarios requires a 12V-230V inverter.

However one drawback of using inverters is the constant noise made by the integrated cooling fan.

ENGINEERS ARE TEACHING ROBOTS TO DISOBEY!

They say its for our own benefit.........we sure hope so


                            

Initially, the headlines that software engineers are teaching robots to disobey their human masters does sound slightly troubling: should we really permit the artificial intelligence systems for the future to say no to us? But once you believe it through, you will see why such a feature might actually end up saving your life.

CAN LOOSING WEIGHT GET US TO MARS?

                Utralight metal show promising future.... 

 

A brand new ultralight metal has one aerospace company pondering applications in the manufacturing of airliners, primarily within the plane, that may help reduce the weight of an aircraft. “The lightest metal ever,” recently acknowledged by Boeing and produced by HRL Laboratories, is manufactured out of a microlattice core that is 99.99% air and has absorption properties that enable it to spring back into shape. Developers say it has got the potential to be used within an airplane for flooring and structural uses within a fuselage. Dr. Tobias Schaedler, HRL senior scientist, says ultralight cores might be employed for sandwich panels, overhead bins or similar pieces. With the potential to greatly reduce the weight of an aircraft, airlines could save an incredible number of dollars in fuel costs. 

Wi-Fi can power the next billion devices!

       The UW team used ambient signals from this Wi-Fi router to power
sensors in a low-resolution camera and other devices.

 

University of Washington engineers have developed a story technology
that works on the Wi-Fi router -- a way to obtain ubiquitous but untapped energy
in indoor environments -- to power devices.

Can graphene hybrid be used to manipulate electromagnetic radiation?

New research led by Exeter University has shown how the unique
properties of graphene can be used to produce artificial structures that
can control and manipulate electromagnetic radiation over different
wavelengths.

why is it so hard to loose weight?

We are designed to seek food – our drive to do so is vital to the survival and we have a complex system to control this. Recent research shows that following fat loss, degrees of circulating hormones which affect our appetite often promote over-eating and weight regain.
