Robots that can minimize damage to tissue with sub-millimeter accuracy and allow surgeons to operate on patients remotely are expected to be a $6.4 billion industry by 2020.

As far back as 2008, studies showed that patients undergoing minimally invasive heart-bypass surgery using a robot had a shorter hospital stay, faster recovery, fewer complications and a better chance that the bypassed vessels would remain open.

Aerogels are among the world’s lightest materials. Graphene aerogel, a record holder in that category, is so light that a large block of it wouldn’t make a dent on a tiny ball of cotton. Water is about one thousand times more dense. The minimal density of aerogels allows for a number of possible applications, researchers have found, ranging from soaking up oil spills to “invisibility” cloaks.


Now, scientists from State University of New York (SUNY) at Buffalo and Kansas State University report in the journal Small that they have found a way to 3D print graphene aerogel, which has only been used in lab prototypes. This technology will make the material much easier to use, and open it, and hopefully other aerogel materials, up to wider applications.


Graphene is just a single layer of carbon atoms. Since it was isolated for the first time in 2004, it has been touted as a wonder material for its strength, pliability and conductivity. Aerogel is essentially a gel where the liquid is replaced by air. Graphene aerogel is known to be highly compressible (so it can bear pressure without breaking apart) and highly conductive (so it can carry electricity efficiently). The very structure of the material that gives it these properties, however, makes it difficult to manufacture using 3D printing technology.


SUNY Buffalo and Kansas State University researchers came up with a solution. They mixed graphene oxide—graphene with extra oxygen atoms—with water and deposited layers on a surface at -25°C. This instantly froze each layer, and allowed the undisrupted construction of the aerogel, with ice as its support.

The Museum of Modern Art launches Seeing Through Photographs, its first massive open online course for a general audience, available on Coursera starting February 10, 2016. Using works from MoMA’s expansive collection as a point of departure, the course encourages participants to look critically at photographs through the diverse ideas, approaches, and technologies that inform their making. Seeing Through Photographs can be found at coursera.org/learn/photography.

Why do digital rights matter?

As we increasingly conduct our lives online – shopping, socializing and sharing information – our digital rights, particularly the rights to privacy and freedom of expression, are becoming more important. We need to understand how our data is being used by companies, governments and internet giants such as Facebook and Google. Is it being handled fairly and scrupulously, or sold or shared without our consent?

Revelations about surveillance programmes and digital hacking have sparked political and diplomatic wrangles. National Security Agency (NSA) whistleblower Edward Snowden has called for new international laws to protect data privacy, arguing that now we know about mass data surveillance it is time to “assert our traditional and digital rights so that we can protect them”.
