Recent advances in embedded three-dimensional (3D) bioprinting have expanded the design space for fabricating geometrically complex tissue scaffolds using hydrogels with mechanical properties comparable to native tissues and organs in the human body. The advantage of approaches such as Freeform Reversible Embedding of Suspended Hydrogels (FRESH) printing is the ability to embed soft biomaterials in a thermoreversible support bath at sizes ranging from a few millimeters to centimeters. In this study, we were able to expand this printable size range by FRESH bioprinting a full-size model of an adult human heart from patient-derived magnetic resonance imaging (MRI) data sets. We used alginate as the printing biomaterial to mimic the elastic modulus of cardiac tissue. In addition to achieving high print fidelity on a low-cost printer platform, FRESH-printed alginate proved to create mechanically tunable and suturable models. This demonstrates that large-scale 3D bioprinting of soft hydrogels is possible using FRESH…

"Irradiated for freshness" written across a juicy mango may raise some eyebrows, but the label has guaranteed Viet Nam exports worth US$20 million a year to the United States.

For the first time in mice, researchers have coated nanoparticles with an ionic liquid that allows the nanoparticles to survive the immune system and deliver drugs to their targeted spot.

For decades, fusion has been the alchemy of our technological age. So, how feasible is the UK’s plan to build a commercially viable fusion power plant by 2040?

It has been a little over three months since the launch of our first operational satellite Capella-2 (formerly named Sequoia) and I can tell you that this has been the most exciting three months of our journey after founding Capella only four years ago. We made history with this launch as the first and only […]

An MIT-designed atomic clock uses entangled atoms to keep time even more precisely than its state-of-the-art counterparts. The design could help scientists detect dark matter and study gravity’s effect on time.
