Apr 12, 2023 (Nanowerk News) Last fall, Professor Seokheun “Sean” Choi and his Bioelectronics and Microsystems Laboratory published their research into an ingestible biobattery activated by the Ph factor of the human intestine. Now, he and PhD student Maryam Rezaie have taken what they learned and incorporated it into new...
Multifunctional patch offers early detection of plant diseases, other crop threats
Apr 12, 2023 (Nanowerk News) Researchers from North Carolina State University have developed an electronic patch that can be applied to the leaves of plants to monitor crops for different pathogens – such as viral and fungal infections – and stresses such as drought or salinity. In testing, the researchers...
4 ways that AI can help students
Apr 12, 2023 (Nanowerk News) As artificial intelligence systems play a bigger role in everyday life, they’re changing the world of education, too. OpenAI’s ChatGPT, Microsoft’s Bing and Google’s Bard all come with both risks and opportunities. I am a literacy educator and researcher, and here are four ways I...
Graphene claims yet another superlative
Apr 12, 2023 (Nanowerk News) In a paper published in Nature ("Giant magnetoresistance of Dirac plasma in high-mobility graphene"), researchers from The University of Manchester report record-high magnetoresistance that appears in graphene under ambient conditions. Materials that strongly change their resistivity under magnetic fields are highly sought for various applications...
Hammock for brain organoids
Apr 12, 2023 (Nanowerk News) Nerve cells communicate through chemical signals (neurotransmitters), which are converted into electrical signals that pass information from one nerve cell to the next. This is also the way in which the neurons in the brain organoids communicate with each other. "To find the causes of...
Backscattering protection in integrated photonics is impossible with existing technologies
Apr 14, 2023 (Nanowerk News) The field of integrated photonics has taken off in recent years. These microchips utilise light particles (photons) in their circuitry as opposed to the electronic circuits that, in many ways, form the backbone of our modern age. Offering improved performance, reliability, energy efficiency, and novel...
Researchers find the key to overcome the limits in X-ray microscopy?
Apr 12, 2023 (Nanowerk News) X-ray microscopes have the advantage of penetrating most substances, so internal organs and skeletons can be observed non-invasively through chest X-rays or CT scans. Recently, studies to increase the resolution of X-ray imaging technology are being actively conducted in order to precisely observe the internal...
Simple but revolutionary modular organoids
Apr 11, 2023 (Nanowerk News) A team led by Masaya Hagiwara of RIKEN national science institute in Japan has developed an ingenious device, using layers of hydrogels in a cube-like structure, that allows researchers to construct complex 3D organoids without using elaborate techniques. The group also recently demonstrated the ability...
Precision magnetics could be game-changer for therapy-resistant brain cancers
Apr 11, 2023 (Nanowerk News) Scientists at The Hospital for Sick Children (SickKids) and the University of Toronto (U of T) have combined forces to develop a new approach to potentially treat tumour cells, called mechanical nanosurgery, even for aggressive, chemoresistant cancers. Glioblastoma (GBM) is the most common and aggressive...
Researchers devise new system for turning seawater into hydrogen fuel
Apr 11, 2023 (Nanowerk News) Seawater’s mix of hydrogen, oxygen, sodium and other elements makes it vital to life on Earth. But that same complex chemistry has made it difficult to extract hydrogen gas for clean energy uses. Now, researchers at the Department of Energy's SLAC National Accelerator Laboratory and...
