Printing mechanical sensors

Researchers at the university of Washington have teamed up; engineers and chemists have been working together to invent a way to print, using a 3D printer mechanical sensors. The material changes its structure under stress and this result in color change that can be easily observed. The 3D printer used …

She looks happy, said the computer

I posted few weeks ago some thoughts on the progress of computers in recognizing objects in an image, in particular I mentioned the image recognition advances made by Google. Now I read a paper written by University of Rochester researchers reporting on the progress made by computers (applications) in recognising emotions present …

Unexpected (to me) twist on 3D printing

It is really true that for any technology upside there is a dark downside! I run few days ago on this news published by Forbes on the possibility to print a gun in your home, by using a 3D printer. The founder of Defense Distributed, Cody Wilson, received a letter from the US …

Picking up single cells with robotic hand

Nanotech, at least intended in sense of extreme miniaturisation, is making progress as scientists understand better and better the structure of matter and learn how to turn this to their advantage by creating "smart" materials that can react to external stimuli. This is the case of researchers at the Johns …

Virtual Viruses

Just few days ago I mentioned the complexity of studying the folding of molecules (in that post I was referring to RNA). It is so complex that supercomputers are used to calculate the way a protein can fold. And yet, understating the possibile folding is crucial because the folding creates …

Don’t you have the green thumb?

My wife has a green thumb, she can transform our home into a forest for what I can see. Would she leave the plants caring to me, desertification would quickly ensue. I have always attributed this to some sort of extra-sensorial capabilities that you either have or have not. Now …

Gotcha!

ICT at the molecular level is what I see in this news from the University of Leeds informing that a team of researchers (actually three teams that have been worked sequentially since 2012) has cracked the code used by RNA virus (like the rhinovirus,the nasty bug giving cold to over a billion people …

Multiplying solar panel efficiency

Ever noticed those big slats protruding from satellites (in photos and movies, I mean…). They are used to harvest Sun light to convert it into electricity. That is an unlimited source of energy that can be used by space craft. However, harvesting it requires very large panels and the more …

Creating an optical antenna

We are used to the idea of radio antennas, we see them everywhere. On the contrary the concept of an optical antenna sounds unusual. As a matter of fact optics is about waves, similar to radio. It just looks into waves at a higher frequency (and it prefers to talk …

Micro-supercapacitors based on graphene

Batteries are still the weak part in any portable electronic system, despite of the progress made in their chemistry. One of the weakest point is the time it takes to recharge them. Supercapacitors, basically condenser, on the other hand can be recharged in a blink of an eye but the …
