4D bioengineering materials bend, curve like natural tissue

Posted by in categories: bioengineering, biotech/medical

Tissue engineering has long-depended on geometrically static scaffolds seeded with cells in the lab to create new tissues and even organs. The scaffolding material—usually a biodegradable polymer structure—is supplied with cells and the cells, if supplied with the right nutrients, then develop into tissue as the underlying scaffold biodegrades. But this model ignores the extraordinarily dynamic morphological processes that underlie the natural development of tissues. Now, researchers at the University of Illinois Chicago have developed new 4D hydrogels—3D materials that have the ability to change shape over time in response to stimuli—that can morph multiple times in a preprogrammed or on-demand manner in response to external trigger signals. In a new Advanced Science study, the UIC researchers, led by Eben Alsberg, show that these new materials may be used to help develop tissues that more closely resemble their natural counterparts, which are subject to forces that drive movement during their formation.

World’s First Supersonic Unmanned Combat Drone Reaches Speeds Of Over 1,500mph

Posted by in categories: drones, robotics/AI, space travel

It can exceed the speed of sound, hitting an astonishing Mach 2.1! 😲🤯


A new combat drone has been created that can hit speeds of more than 1500mph.

The drone is much bigger than the ones you’ll have seen floating around your local parks, however, and looks more like a small spaceship.

Interesting pattern in cross-sections observed in F + HD → HF + D reaction

Posted by in categories: chemistry, quantum physics

A team of researchers from the University of Science and Technology of China, the Chinese Academy of Sciences and the Southern University of Science and Technology, has discovered a thought-provoking pattern in cross-sections observed in an F + HD → HF + D reaction. In their paper published in the journal Science, the group describes their double-pronged approach to learning more about the role of relativistic spin-orbit interactions in chemical reactions. T. Peter Rakitzis, with the University of Crete, and IESL-FORTH, has published a Perspectives piece in the same journal issue outlining the difficulty of studying chemical reactions at the quantum level and the work done by the team in China.

Quantum Building Blocks to Produce Exotic Electronic and Magnetic Properties

Posted by in categories: particle physics, quantum physics

Oak Ridge National Laboratory scientists demonstrated that an electron microscope can be used to selectively remove carbon atoms from graphene ’s atomically thin lattice and stitch transition-metal dopant atoms in their place.

This method could open the door to making quantum building blocks that can interact to produce exotic electronic, magnetic and topological properties.

This is the first precision positioning of transition-metal dopants in graphene. The produced graphene-dopant complexes can exhibit atomic-like behavior, inducing desired properties in the graphene.
