Using a new technique they call ‘in-air microfluidics’, University of Twente scientists succeed in printing 3D structures with living cells. This special technique enable the fast and ‘in-flight’ production of micro building blocks that are viable and can be used for repairing damaged tissue, for example.

Microfluidics is all about manipulating tiny drops of fluid with sizes between a micrometer and a millimeter. Most often, chips with tiny fluidic channels, reactors and other components are used for this: lab-on-a-chip systems...

Andromeda galaxy

CU Boulder researchers have discovered a mechanism that explains the persistence of asymmetrical stellar clusters surrounding supermassive black holes in some galaxies and suggests that during post-galactic merger periods, orbiting stars could be flung into the black hole and destroyed at a rate of one per year.

A supermassive black hole’s gravity creates a nuclear star cluster surrounding it, which gravitational physics would expect to be spherically symmetric. However, several galaxies – including nearby Andromeda – have been observed with an asymmetrical star cluster that takes the form of a disk instead. Eccentric disks are suspected to be formed in the wake of a recent merger between two gas-rich galaxies.

Within the disk, each star follows an elliptical orbit that re...

Credit: Aleo BME A biopolymer liquid bandage for wound care

Biomaterials and medical device company Aleo BME has received notification from the U.S. Federal Drug Administration that it has been approved for the sale and licensing of ElaSkinTM as a liquid bandage for the protection and treatment of a broad set of skin conditions and injuries. ElaSkin’sTM development validates Aleo BME’s approach to biopolymer production and characterization and demonstrates an ability to enter critical regulated markets and produce medical devices that can benefit large patient populations.

The compelling features of ElaSkinTM include: transparency, elasticity, clean and easy removal, water resistance, rapid drying, bacterial impermeability and the sensation of true protection...

Lead author Fabian Schneider, a Hintze Research Fellow in the University of Oxford’s Department of Physics, said: “We were astonished when we realised that 30 Doradus has formed many more massive stars than expected.”

Astronomers have revealed an ‘astonishing’ overabundance of massive stars in a neighboring galaxy. The discovery, made in a gigantic star-forming region of the Large Magellanic Cloud galaxy, has ‘far-reaching’ consequences for our understanding of how stars transformed the pristine Universe into the one we live in today. As part of the VLT-FLAMES Tarantula Survey (VFTS), the team used ESO’s Very Large Telescope to observe nearly 1,000 massive stars in 30 Doradus, a gigantic stellar nursery also known as the Tarantula Nebula...
