Nanobots are machines whose components are at the nano-scale (one millionth of a millimetre), and can be designed in such a way that they have the ability to move autonomously in fluids. Although they are still in the research and development phase, very significant advances are being made to make nanorobots a reality in the field of biomedicine. Their applications are very varied: from the identification of tumour cells, to the release of drugs in specific locations of the body. Nanorobots powered by catalytic enzymes are among the most promising systems because they are fully biocompatible and can make use of fuels already available in the body for their propulsion. However, understanding the collective behaviour of these nanorobots is essential to advance towards their ....

Facial recognition ID with a twist: Smiles, winks and other facial movements for access

Using your face to unlock your phone is a pretty genius security protocol. But like any advanced technology, hackers and thieves are always up to the challenge, whether that s unlocking your phone with your face while you sleep or using a photo from social media to do the same.
Like every other human biometric identification system before it (fingerprints, retina scans) there are still significant security flaws in some of the most advanced identity verification technology. Brigham Young University electrical and computer engineering professor D.J. Lee has decided there is a better and more secure way to use your face for restricted access. ....

Recruiting and selecting the proper sailors for specific tasks in the U.S. Navy has proven tricky, with costs rising yearly as the military seeks to match sailors with appropriate specialties. A University of Houston professor of psychology and a team of collaborators is out to save the military money and streamline the process by developing a new personnel selection process, the Manpower and Personnel Assessment Battery (MPAB). ....

A groundbreaking new study led by University of Minnesota Twin Cities researchers from both the College of Science and Engineering and the Medical School shows for the first time that lab-created heart valves implanted in young lambs for a year were capable of growth within the recipient. The valves also showed reduced calcification and improved blood flow function compared to animal-derived valves currently used when tested in the same growing lamb model. ....

Flat brain organoids grown on 3D-printed scaffolds show intrinsic gyrification

E-Mail
The research, by an international team from the Autonomous University of Madrid and the Technical University of Denmark, used 3D printing to create scaffolds for engineered flat brain organoids. The scaffolds allowed the brain organoid size to be significantly increased and after 20 days, self-generated folding was observed. Their results are published in the IOP Publishing journal
The work aims to address several of the shortcomings of existing brain organoids. One of the lead authors, Theresa Rothenbücher, said: The lack of vascularization leads to diffusion limitations for nutrients and oxygen, resulting in a necrotic tissue core for organoids larger than approximately 500 μm. In an attempt to solve this problem, brain organoids have been vascularized. While including endothelial cells in the culture system increases the complexity of the model, the generated vessel structures show no functionality (blood flow) in vitro. We are able to circumvent this issue ....
