Israeli Researchers Print 3D Heart Using Patient’s Own Cells
Posted by Klaus Baldauf in categories: biotech/medical, materials
Israeli researchers have printed a 3D heart using a patient’s own cells, something they say could be used to patch diseased hearts — and possibly, full transplants.
The heart the Tel Aviv University team printed in about three hours is too small for humans — about 2.5 centimeters, or the size of a rabbit’s heart. But it’s the first to be printed with all blood vessels, ventricles and chambers, using an ink made from the patient’s own biological materials.
Can water reach minus 263 degrees Celsius without turning into ice? Yes it can, say researchers from ETH Zurich and the University of Zurich, if it is confined in nanometre-scale lipid channels.
Making ice cubes is a simple process: you take a plastic ice-cube tray like you’d find in most households, fill it with water and put it in the freezer. Before long, the water crystallises and turns to ice.
If you were to analyse the structure of ice crystals, you’d see that the water molecules are arranged in regular 3-dimensional lattice structures. In water, by contrast, the molecules are unorganised, which is the reason that water flows.

Physicists Have Found an Entirely New Type of Superconductivity
Posted by Shane Hinshaw in categories: materials, physics
One of the ultimate goals of modern physics is to unlock the power of superconductivity, where electricity flows with zero resistance at room temperature.
Progress has been slow, but in 2018, physicists have made an unexpected breakthrough. They discovered a superconductor that works in a way no one’s ever seen before — and it opens the door to a whole world of possibilities not considered until now.
In other words, they identified a brand new type of superconductivity.

A new graphene foam stays squishy at the coldest temperatures
Posted by Genevieve Klien in categories: materials, space
Researchers have now made a material that is superelastic even at extremely cold temperatures, which could be helpful in space.
O.o.

Novel membrane material removes more impurities without the need for toxic solvents
Posted by Quinn Sena in categories: energy, materials
Natural gas and biogas have become increasingly popular sources of energy throughout the world in recent years, thanks to their cleaner and more efficient combustion process when compared to coal and oil.
However, the presence of contaminants such as carbon dioxide within the gas means it must first be purified before it can be burnt as fuel.
Traditional processes to purify natural gas typically involve the use of toxic solvents and are extremely energy-intensive.

Light-activated wrap designed to fix concrete structures
Posted by Genevieve Klien in categories: humor, materials
Utilizing tape to repair or reinforce concrete structures may seem like some hillbilly fix-it joke, but in fact that’s just what fiber reinforced polymer (FRP) sheets are used for. Now, scientists have developed what they say is a better FRP, that halves the number of people and amount of time required for application.
