Wall Street banks are buzzing about blockchain.
Goldman Sachs says the technology “has the potential to redefine transactions” and can change “everything.”
JPMorgan last month announced it was launching a trial project with the blockchain startup led by its former executive, Blythe Masters. Her company, Digital Asset Holdings, has secured funding from Goldman, Citi, ICAP, and a boatload of other financial firms.

In an unusual move Nano Dimension, an Israeli company called focused on printing electricity-conducting nano-material ink, is expanding into the biotech sector.
Gedalyah Reback 1 day ago.
Nano Dimension, a 3D bioprinting company located in Ness Ziona, Israel, has successfully tested a prototype for a new type of printer that uses stem cells to produce 3D models. The trial was done in conjunction with Haifa-based Accellta.

(Phys.org)—For more than 100 years, scientists have debated the question: when light travels through a medium such as oil or water, does it pull or push on the medium? While most experiments have found that light exerts a pulling pressure, in a new paper physicists have, for the first time, found evidence that light exerts a pushing pressure.
The scientists suggest that this apparent contradiction is not a fundamental one, but can be explained by the interplay between the light and the fluid medium: if the light can put the fluid in motion, it exerts a pushing force; if not, it exerts a pulling force.
The researchers, Li Zhang, Weilong She, and Nan Peng at Sun Yat-Sen University in Guangzhou, China, and Ulf Leonhardt at the Weizmann Institute of Science in Rehovot, Israel, have published a paper on the first evidence for the pushing pressure of light in a recent issue of the New Journal of Physics.
Daniel G. Nocera, the Harvard professor who made headlines five years ago when he unveiled an artificial leaf, recently unveiled his latest work: an engineered bacteria that converts hydrogen and carbon dioxide into alcohols and biomass. One can be used directly as fuel to power vehicles that run on conventional fuels, while the other can be burned for energy.
Researchers used high-purity graphene and observed for the first time that its charged particles behave like fluid with relativistic properties. This discovery holds promise for thermoelectric devices as well as for studying the behavior of black holes and celestial bodies.

Electrons in graphene appear for the first time to behave like a liquid, potentially leading to devices that can efficiently convert heat to electricity and chips that can precisely model the behavior of black holes and high-energy celestial objects.
Since it was discovered 10 years ago, graphene has been hailed as a wonder material: extremely light, strong, hard and among the most conductive items on Earth. The challenge, however, is studying the unique properties of this one-atom-thick material.
