3D-printable gels with improved and highly controlled properties can be created by merging micro- and nano-sized networks of the same materials harnessed from seaweed, according to new research from North Carolina State University. The findings could have applications in biomedical materials - think of biological scaffolds for growing cells - and soft robotics.
Described in the journal
Nature Communications, the findings show that these water-based gels - called homocomposite hydrogels - are both strong and flexible. They are composed of alginates - chemical compounds found in seaweed and algae that are commonly used as thickening agents and in wound dressings. ....

Ecology-inspired mathematical models to understand social networks


 E-Mail
The ease with which anyone can create online content for free, especially on social media, has led to superabundance of information being one of the defining characteristics of today s communication systems. This situation has resulted in increasingly intense competition for attention, which has become a scarce good. The researchers from the Complex Systems group (CoSIN3) at the UOC s Internet Interdisciplinary Institute (IN3) María José Palazzi and Albert Solé professor at the Faculty of Computer Science, Multimedia and Telecommunications? , led by Javier Borge, have participated in the design of an ecology-inspired mathematical model that makes it possible to break down and predict interaction patterns in a system as complex as the Twitter social network. ....

In 1961, the Nobel prize winning theoretical physicist Eugene Wigner proposed what is now known as the Wigner s friend thought experiment as an extension of the notorious Schroedinger s cat experiment. In the latter, a cat is trapped in a box with poison that will be released if a radioactive atom decays. Governed by quantum mechanical laws, the radioactive atom is in a superposition between decaying and not decaying, which also means that the cat is in a superposition between life and death. What does the cat experience when it is in the superposition? Wigner sharpened the question by pushing quantum theory to its conceptual limits. He investigated what happens when an o ....
